Car Electronics 2012

The Year of The EV article tells that We can dub 2011 the year of the EV (electric vehicles) and gives a timeline what happened 2011. The end result is that today there are enough Volts on the road (along with competitors like Nissan’s Leaf, various hybrids, and an electric Ford Focus) that it might be safe to suggest that the electric car is here to stay.

There has been many different car charging connectors in use on electronic vehicles. Electric Car Charging Standards Split article tells that many car manufacturers have agreed on a single EV charging port connector standard that has been in development by the Society of Automotive Engineers (SAE) for several years. European car companies have been divided on standards for both AC and DC charging. The new single connector will support fast DC charging as well as be backward compatible with the J1772 AC charger that is standard on many plug-in electric vehicles today. I think that use of that standard will rise in 2012, and common charging standard will speed up the EV deployment.

Automotive electronics: What’s hot in 2012 article tells that in automotive electronics, 2012 looks to be a year of consolidation as technologies introduced previously become more widespread across model lines. In particular, voice recognition, with different features and interfaces, is seen as a way of distinguishing one brand from another, while electrified power trains in the form of hybrids and pure electric drives will be available in more models. In keep costs down driven auto industry the more mature the technology that goes into a car, the less risk of failure and costly warranty claims.

Cars and smartphones start to communicate using MirrorLink technology to allow new features. MirrorLink™ has been developed with the objective to provide a technology, offering seamless (extremely simple from the consumer perspective) connectivity between a smart phone and the in-vehicle infotainment system. It uses IP technologies in order to be independent of the physical transport mechanism and supports many car connectivity solutions (Bluetooth, WLAN, USB etc.). Whereas MirrorLink™ does allow any legacy application on the mobile device to show-up on the car display, it specifically enables easy development of mobile device based automotive applications.

Ethernet for Vehicles is gaining momentum in in the car. Ethernet for Vehicles Advances article tells that Ethernet technology in the car (a concept that was once unthinkable for the automotive industry) has been gaining momentum lately. Special interest group, known as the OPEN (One-Pair-Ether-Net) SIG, is aimed at driving broad-scale adoption of Ethernet in vehicles, largely to serve the expected boom of camera-based applications in cars. Many vehicles now have backup cameras, and many others are going to add cameras for such applications as lanekeeping, adaptive cruise control, and collision avoidance.

There is going to be an increasing number of Driver Information applications that involve displaying complex images and graphics. Xilinx Paves the Way for a New Generation of Automotive Driver Assistance and Infotainment Systems at CES 2012. World’s first Field Programmable Gate Array (FPGA) based Ethernet Audio/Video Bridging (EAVB) network implementation optimized for carrying high-speed data traffic within the automobile was shown at CES 2012. The IEEE 802.1 EAVB standard is already gaining the attention of a number of leading automotive manufacturers even though the specifications are still being finalized. OMG! Amazing home displays and automotive Ethernet AVB stuff from Xilinx article gives some more details what is expected in near future.

New electronics features are making challenges for developers. Automotive Electronics: Do We Really Need All This Stuff? article tells that everyone in the auto industry knows that the number of electronic control units (ECUs) in vehicles is nearing the point of unmanageability. Low-end vehicles now incorporate between 35 and 40 ECUs, while luxury cars may have 80 or more. “We’re right up against the limit right now. We need to find unique ways to integrate features and functions, and give our customers what they want without overloading our controllers.” The number of automotive features and functions keeps rising.

Would Cellphone Ban Secure Car Safety? article tells that the proliferation of in-car entertainment technologies (internet routers, smartphone links, MP3 connections, capacitive touch screens, etc.) are great for selling cars. Auto executives understand what consumers want: Many people don’t want a car with no extra features. Those new extra features have also sparked a serious debate about driver distraction dangers. “According to NHTSA [the National Highway Traffic Safety Administration], more than 3,000 people lost their lives last year in distraction-related accidents.” “You’re dealing with human nature here. People want what they want. And sometimes they want more than they should have.”

    Tesla’s self-driving cars coming to US within 3 months, with autopilot enabled only on major roads; regulatory questions remain

    Elon Musk Says Self-Driving Tesla Cars Will Be in the U.S. by Summer
    http://www.nytimes.com/2015/03/20/business/elon-musk-says-self-driving-tesla-cars-will-be-in-the-us-by-summer.html

    on Thursday, Elon Musk, chief executive of Tesla, took a big step in that direction when he announced that the maker of high-end electric cars would introduce autonomous technology by this summer. The technology would allow drivers to have their cars take control on what he called “major roads” like highways.

    Mr. Musk said that a software update — not a repair performed by a mechanic — would give Tesla’s Model S sedans the ability to start driving themselves, at least part of the time, in a hands-free mode that the company refers to as autopilot.

    But some industry experts said serious questions remain about whether such autonomous driving is actually legal and are skeptical that Model S owners who try to use autopilot would not run afoul of current regulations.

    “There’s a reason other automakers haven’t gone there,” said Karl Brauer, an analyst with Kelley Blue Book. “Best case scenario, it’s unclear. If you’re an individual that starts doing it, you’d better hope nothing goes wrong.”

    Crowd sourcing speeds image classification development
    http://www.vision-systems.com/articles/print/volume-20/issue-3/features/crowd-sourcing-speeds-image-classification-development.html?cmpid=EnlVSDMarch232015

    One of the major challenges in building automated supervised image classification systems is the amount of training data that needs to be correctly identified. In such systems, hundreds or thousands of correctly labeled images need to be presented to the system since more labeled data will result in a system more effective than one where just a few data is presented to the classifier

    “In the development of an obstacle avoidance system for an automotive manufacturer,” says Dr. Daniel Kondermann, President of Pallas Ludens (Mannheim, Germany; http://www.pallas-ludens.com), “hundreds of thousands of images such as automobiles, pedestrians, trees, and other obstacles need to be properly identified at multiple scales.” Similarly, to build such a system to identify brain tumors in MRI images, a physician must isolate the relevant pixel regions in multiple images. Although global segmentation algorithms may be used to perform this task,” says Kondermann, the results of these algorithms may be ambiguous and not as accurate as those performed by an expensive human operator.”

    Realizing this, Pallas Ludens has developed an elegant way to solve the task of rapid image classification development. Instead of requiring a single trained professional to identify multiple images or objects within images, the company has leveraged the power of crowd sourcing to complete the task

    “Companies in the medical, automotive and entertainment industries require classification systems that must be as accurate as possible,”

    Opel headlights gaze following

    GPS fix has already been developed on the basis of the headlights, which are able to anticipate the bends. German Opel goes far beyond this. Its new head light technology following on the driver’s eye movements. The technique has worked for several years.

    Originally, it was a simple webcam, which was followed by the nose and the eye position and concluded that they were based on the gaze direction. This was a promising technology, but Opel failed to develop a system that would process the process data fast enough.

    The development team began instead to improve your eye movements, the following algorithms. Now the camera is able to check the position of the eye in dark and low-light 50 times per second.

    The data processing is now almost in real time.

    Opel, the technology is still one problem: human eye uncontrolled movement, which in practice it “bounces” back and forth all the time.

    Will technology help us escape urban commuting hell?

    Fed up of endless traffic jams and overcrowded trains? Then how about commuting to work in your own jetpack?

    New Zealand firm Martin Aircraft Company is building a one-person jetpack scheduled to go on sale in 2016. And it actually seems to work.

    Although currently slated for use by emergency services, it is only a small leap to imagine it in the hands of commuters.

    Meanwhile cities’ populations are expanding rapidly, and congestion, pollution and travel stress look likely to rise in tandem, unless we seriously reform our creaking urban transport systems.

    Some cities are investing in big infrastructure projects, such as London’s Crossrail, while others see the future lying with greener transport alternatives, like electric buses or bike-sharing schemes.

    Copenhagen’s e-bikes have tablet computers installed between the handlebars with onboard GPS navigation. Users can book and pay for the bikes via their smartphones.

    In other cities around the world, authorities are rolling out fleets of electric buses and trialling wireless charging, where buses drive onto special platforms to be charged when in the depot.

    In the UK, the Carbon Trust believes that by 2050 up to half of the country’s light duty vehicles could be powered by hydrogen fuel cells, with water as the only waste product.

    How can I switch off GPS in my rented car?
    The controversial Hertz NeverLost syste mcannot be switched off, disconnected or removed, says Rick Maybury
    http://www.telegraph.co.uk/technology/advice/11441270/How-can-I-switch-off-GPS-in-my-rented-car.html

    I have just returned from a family holiday to the US and we rented a mid-size car for the duration. Although I declined the GPS option, I prefer to use my own, a unit was fitted in the car. The rental car assistant was adamant that all cars had them now, and I only had to pay for it if I used it. It turned out be an absolute pest and even though I switched it off, it came back on every time I started the engine with an annoying jungle.

    This would be the controversial Hertz NeverLost system, an increasingly common sight in US rental cars, and not just from Hertz. Some recent NeverLost terminals do indeed have built-in cameras, pointing at the vehicle cabin and apparently it will only be used for video chats with rental company reps, should you seek assistance. They can also be used to track the user’s whereabouts, locate stolen vehicles, monitor speed and driving technique as well as doing quite useful things like navigating and route planning. You cannot switch it off, disconnect or remove the unit though, but it seems unlikely that the camera (and microphone) are constantly monitored or recorded and this would be potentially illegal in some States. If you are concerned about privacy the device’s eyes and ears are easily neutralised with some strategically placed sticky tape or chewing gum.

    Ford: Our latest car gizmo will starve you of fuel if you’re speeding
    Fighting automatic regulation with automatic adherence
    http://www.theregister.co.uk/2015/03/25/ford_auto_speed_limit_obedience_fuel_starvation/

    Ford has announced a new intelligent speed limiter system which reads traffic signs and reduces fuel flow to keep your vehicle within the speed limit.

    As much as the petrolhead lobby decries the direct correlation the road safety brigade makes between speed and safety, current legislation means that if you’re driving too fast, regardless of how safely, you’ll usually get fined.

    While a traffic officer can make a judgment call, ticket-bots won’t be quite so lenient. Now the Ford tech is fighting automatic regulation with automatic adherence.

    The Intelligent Speed Limiter combines current Ford technologies: the Adjustable Speed Limiter and Traffic Sign Recognition, which are both already available on models including the Focus, Mondeo, and Kuga SUV.

    At speeds of between 20mph and 120mph the system smoothly decelerates by restricting the fuel supplied to the engine, rather than applying the brakes. Should travelling downhill cause the vehicle to exceed the legislated speed an alarm is sounded.

    Drivers can temporarily override the system by firmly depressing the accelerator pedal.

    Ford’s New Car Tech Prevents You From Accidentally Speeding
    http://tech.slashdot.org/story/15/03/24/2152209/fords-new-car-tech-prevents-you-from-accidentally-speeding

    An anonymous reader sends word of Ford’s new “Intelligent Speed Limiter” technology, which they say will prevent drivers from unintentionally exceeding the speed limit. When the system is activated (voluntarily) by the driver, it asks for a current maximum speed. From then on, a camera mounted on the windshield will scan the road ahead for speed signs, and automatically adjust the maximum speed to match them.

    Could this spell the end for speeding tickets?
    http://social.ford.co.uk/could-this-spell-the-end-for-speeding-tickets/

    Breaking the speed limit is not something we always do on purpose. All the same, it can be costly in terms of fines, and driving bans, as well as playing a significant role in many road accidents.

    In the U.K. alone, in 2013, more than 15,000 drivers received fines of £100 or more for speeding.

    We are now launching Intelligent Speed Limiter, a technology that could help prevent drivers from unintentionally exceeding speed limits.

    The system monitors road signs with a camera mounted on the windscreen, and slows the vehicle as required. As the speed limit rises, the system allows the driver to accelerate up to the set speed – providing it does not exceed the new limit.

    “Drivers are not always conscious of speeding and sometimes only becoming aware they were going too fast when they receive a fine in the mail or are pulled over by law enforcement,” said Stefan Kappes, active safety supervisor, Ford of Europe. “Intelligent Speed Limiter can remove one of the stresses of driving, helping ensure customers remain within the legal speed limit.”

    A $60 Gadget That Makes Car Hacking Far Easier
    http://www.wired.com/2015/03/60-gadget-thatll-make-car-hacking-easier-ever/

    The average automobile today isn’t necessarily secured against hackers, so much as obscured from them: Digitally controlling a car’s electronics remains an arcane, specialized skill among security researchers. But that’s changing fast. And soon, it could take as little as $60 and a laptop to begin messing around with a car’s digital innards.

    Tomorrow at the Black Hat Asia security conference in Singapore, 24-year-old Eric Evenchick plans to present a new device he calls the CANtact. The open source board, which he hopes to sell for between $60 and $100, connects on one end to a computer’s USB port, and on the other to a car or truck’s OBD2 port, a network port under its dashboard. That makes the CANtact a cheap interface between any PC and a vehicle’s controller area network or CAN bus, the collection of connected computers inside of every modern automobile that control everything from its windows to its brakes.

    With just that go-between gadget and the open source software that Evenchick is releasing for free, he hopes to make car hacking a far cheaper and more automated process for amateurs.

    it’s meant to foster hobbyist car hacking and security research that can expose and help fix a car’s vulnerabilities.

    The average coder isn’t familiar with the protocol most cars’ computers rely on to communicate. But Evenchick has written open source software for CANtact that automates much of the manual work of CAN bus hacking.

    The CANtact, of course, can only test security exploits that require physical access, not remote attacks on a car’s network.

    France Is Letting 14-Year-Olds Drive This Tiny Electric Car
    http://www.wired.com/2015/03/france-letting-14-year-olds-drive-tiny-electric-car/

    Being 14 sucks.

    Unless, that is, you live in France. Then you just need to beg your parents to buy you a Renault Twizy, a $7,600 “car” that 14-year-olds can now legally drive.

    The Twizy is a quadricycle, a 1,000-pound, two-seat electric car meant for zipping around cramped European cities. It’s designed to be a safer alternative to bicycles and scooters for the urban set, sporting a 13-horsepower electric motor and enough batteries to take you 60 miles at a maximum speed of 50 mph. It won’t hold much cargo

    The Twizy has airbags, seat belts, two seats, headlights, turn signals—all those things that actual cars have. And, thanks to new legislation in France, youths as young as 14 can now drive the things legally.

    Previously, 14-year olds in France with a road safety certificate (sort of a lightweight-version of a driver’s license) could only ride mopeds. Now, in order to comply with EU regulations, that same certificate now allows holders to drive “quadricycles”.

    As regulated, quadricycles are four-wheeled cars that can’t exceed 28 mph, can’t have a battery pack bigger than 4 kWh (for electric engines, traditional gas and diesel versions can’t have an engine bigger than 50cc), and can’t exceed 770 pounds curb weight.

    Renault says it’s sold some 15,000 Twizys in Europe since launching the thing half a decade ago, and we would love to see the automaker jump the pond and let American teens, or adults, climb in.

    Hands on with Hyundai’s BlueLink car companion app for Android Wear: requires paid subscription and cumbersome PIN, voice commands offer limited functionality

    Can A Smartwatch Make Your Car Smarter? A Week With Hyundai’s BlueLink For Android Wear
    http://www.androidpolice.com/2015/03/24/can-a-smartwatch-make-your-car-smarter-a-week-with-hyundais-bluelink-for-android-wear/

    If you own a reasonably modern car (say, within two or three years old), there’s a significant chance that car has some kind of cellular connectivity embedded in it, and this allows the car to do stuff remotely. Like, start. Or unlock the doors. Or lock them. Or honk the horn. These things have names… like mbrace (Mercedes), AcuraLink, Enform (Lexus), OnStar (GM), MyLincoln, and so on.

    Hyundai’s version, BlueLink, isn’t the most fully-featured of the bunch, to be honest. But, as one of the first and arguably most enthusiastic Android Auto partners, Hyundai’s shown an interest in Android that few automakers have, as evidenced by the fact that BlueLink now has an app for Android Wear. The Wear app does what you’d expect – lock, unlock, remote start, stop, flash lights, honk horn, call roadside assistance, or dial BlueLink. Hyundai is the first auto manufacturer to officially embrace Android Wear, and it’s not difficult to see why – a smartwatch makes a pretty ideal replacement for a lot of key fob functions, in theory. But can it actually replace one yet?

    For now, the answer is no (not that Hyundai claims otherwise). Partly because you obviously still need the key fob to drive the car, and partly because the experience using Wear right now is just not there yet (also battery life duh). But it’s exciting to see where Hyundai (and likely other automakers) will take this concept as it refines and hones the experience and adds features.

    My first day experimenting with BlueLink, I decided I would get the car cooled off before I actually got inside.

    So, how easy is it to send this command? Well, I think it’s fair to say that it’s not as easy as most of us would want it to be in an ideal world.

    First, you have to activate BlueLink on Wear.
    There is no way to voice-ignite your car in a single step.
    Part of the problem here is Wear. Wear doesn’t support custom voice commands yet, and Hyundai would, according to them, add such a thing if Wear allowed it (ie, “OK, Google – start my car”).

    I realize it terrifies insurers, but storing an authenticator token on the watch that lets you skip the PIN would be worth any small risk that might present. After all, while I can understand losing your smartphone and thus wanting PIN entry on that end, you’re unlikely to have both your watch and phone stolen, but not the car keys, and have a thief savvy enough to understand the watch can unlock the car without a code. A watch is usually pretty safe on your wrist, and the watch also doesn’t even work without the phone, so it has secondary authentication already.

    As for use cases, purposes for remote locking and unlocking are there, but obviously they’re mostly backup measures.

    I personally had no problems getting BlueLink to work – just know that when you activate remote ignition, all other remote features are disabled until you then un-start the car

    Spending a bit of time with the service, though, I wasn’t convinced I’d personally want to pay for it. And yes, Hyundai charges a subscription fee for BlueLink, with cost varying on the subscription type (almost all OEMs that have these systems do charge for service on them, by the way), but the cheapest way to do it would be $450 for a 3-year plan (which comes out around $12.50 a month). Sure, you can tack this kind of stuff onto your car payment, but it’s still your money, and you still have to ask if it’s worth it.

    Magnetic Sensors with Integrated Diagnostics for ASIL Compliance
    http://www.eeweb.com/company-blog/allegro_microsystems/magnetic-sensors-with-integrated-diagnostics-for-asil-compliance

    This technical article presents the magnetic sensor integrated circuits (ICs) that provides diagnostics for automotive safety integrity level (ASIL) compliance. The current revolution in intelligent vehicle control systems relies substantially on the rapidly developing physical detection technology called magnetic sensor integrated circuits (ICs). The complexity, reliability, flexibility, and functionality of these non-contacting, magnetic sensor ICs have all but dispelled the need for electromechanical switches in just about every application in latest generation automobiles. Yet, accompanying this increase in usage of complex electronic devices, is a heightened concern over difficult-to-detect, system-level risks. This, in turn, has led the automotive industry to focus on automotive functional safety. The ISO 26262 functional safety standard outlines a development process, including predictive analysis to minimize risk. This process, in turn, requires advanced diagnostics capabilities integrated directly into magnetic sensor IC systems. An examination is made of a new type of magnetic sensor IC that implements integrated diagnostics, using an innovative embedded solid state coil for end to end system test.

    Open the door of any recent-model automobile and you are immediately surrounded by an invisible network of electronic sensors. They detect seat belt buckling, window or sunroof pinching, gear shifter position, engine transmission rotational speed and direction, and camshaft position, to name only a few applications. The penetration of real time sensing into these applications has been made practical by developments in various types of non-contacting magnetic detectors (i.e. Hall effect, Giant Magnetoresistive (GMR), Anisotropic resistive (AMR)). In addition to having very small form factors, these state-of-the-art, solid-state, semiconductor ICs are cost effective, power efficient, non-contacting, and gather a pervasive data stream in the harshest environment of vehicle engines with the subtlety to respond to the slightest of changes in vehicle conditions.

    ICs can provide suboptimal outputs, so automotive use requires additional safety measures to avoid unreasonable residual risk according to Automotive Safety Integrity Levels (ASIL), ISO 26262.

    Helping Tokyo Olympics Tech Drive Succeed
    http://www.eetimes.com/author.asp?section_id=36&doc_id=1326126&

    Japan is faced with challenges that ADAS intends to solve — safer driving.

    What do Advanced Driver Assistance Systems (ADAS) and the 2020 Tokyo Olympic and Paralympics Games have in common? They can both help further the deployment of ADAS technologies.

    When a city hosts the Olympic Games it is immediately faced with the challenge of dealing with a significant increase in visitors that need to move from one place to another in a very safe and secure manner. This is no different for Tokyo, one of the largest and most densely populated areas in the world.

    For example, a recent study in Japan showed that the number of accidents involving aged people is stable, while that involving younger people has decreased. The Japanese government has strongly highlighted the push towards safer driving technologies as part of the 2020 Tokyo Olympics timeline.

    From a business perspective, the upcoming Olympics will provide a perfect venue to showcase ADAS technologies from Japanese car makers.

    One facet of safer driving in the future is autonomous driving.

    But the path to autonomous driving is still a long one from a technical, legal and business perspective.

    We will skip the legal aspects for now and focus on the technical aspects. From a technology standpoint, the development of ADAS will require sensors and software to interpret all sensor data, software and hardware to control the direction and speed of the car, and algorithms and software to implement a skilled driver.

    These technology challenges, although complex, are solvable with the use of the right tools and methodologies that will enable companies to design the right architecture and start system software development, integration and test earlier.

    From a business perspective, automotive companies must deliver these functions at costs that will be acceptable to the consumer and scalability from entry level to high-end vehicles. Development costs, scalability of expected functionality, performance requirements, power management and efficient testing for ISO 26262 will be some of the key development concerns.

    Voltage Translation for Automotive Systems
    http://www.eeweb.com/company-blog/texas_instruments/voltage-translation-for-automotive-systems

    In today’s automotive electronics systems, microcontrollers and peripherals operate off different voltage supplies. This is driven by an effort to reduce power consumption. However, as microcontroller voltages drop, many peripherals continue to need higher voltages. This creates a situation of voltage incompatibility.

    For two devices to interface reliably, the output driver voltages must be compatible with receiver input thresholds. For this condition to be met in mixed voltage systems, a voltage translator is often required. Typically, voltage translation has been done using logic ICs and sometimes several discrete components. This increases board size, component count, and assembly cost.

    TI automotive products include a comprehensive voltage translation portfolio including buffered push-pull and open-drain outputs. These solutions can eliminate the need for multiple ICs, which reduces board real estate and cost. Texas Instruments voltage translation products are compatible with 1.2V CMOS, 1.5V CMOS, 1.8V CMOS, 2.5V CMOS, 3.3V TTL, 3.3V CMOS, 5V CMOS, and 5V TTL.

    “How much warning does a driver need to take back control of a vehicle after they were e-mailing? Is five seconds enough, or do they need 20? These are just some of the issues that need to be resolved,” explained Daimler spokesperson Katharina Becker.

    Car software developers are also struggling to deal with the ethical challenges often raised on the road. For example when faced with the decision to crash into a pedestrian or another vehicle carrying a family, it would be a challenge for a self-driving car to follow the same moral reasoning a human would in the situation.

    “Technologically we can do fully automated self-driving, but the ethical framework is missing,” said Winterkorn.

    Linux Seeks Security, Unity
    http://www.eetimes.com/document.asp?doc_id=1326150&

    Linux is expanding its reach, promising to play a significant role in the Internet of Things. But the open source software needs more attention to interoperability, security and its kernel, according to experts at the Embedded Linux Conference here.

    Jaguar Land Rover came to the event saying it will make open source its connected car software, challenging competitors to do the same.

    Intel is working on subsets of Tizen for IoT.

    The company chose Tizen, in part, because it supports CAN bus, the IVI spec of the Genivi Alliance and HTML5. Land Rover’s open source group with four people and now numbers 40 with plans to double staff this year.

    Use of open source code is helping the car maker reduce the time to market for new technologies to as little as 16 months from 39 previously. “I hope other car companies figure this out because then I get to benefit from their code,”

    Vehicle Reliability Is Up, Especially in Powertrain
    http://www.eetimes.com/document.asp?doc_id=1326152&

    Some cars are more reliable than others, but even the vehicles at the bottom of this year’s Consumer Reports reliability survey are vastly better than those of 20 years ago in the key areas of powertrain and hardware, experts said this week.

    ”A brand new car in 1995 was quite a bit worse than it is today,” Jake Fisher, director of auto testing for Consumers Union, told Design News. “But the overall problem rates haven’t changed much. Engines, transmission, and hardware have gotten better, and electronics have gotten much worse.”

    At the Track With Formula E, the First e-Racing Series
    http://tech.slashdot.org/story/15/03/30/0256247/at-the-track-with-formula-e-the-first-e-racing-series

    Ars is running a story about the new all-electric racing car series first visit to the U.S.. “The pit lane we’re standing in is unusual, and not only because it’s a temporary setup placed in the shadow of American Airlines Arena (home of the NBA’s Miami Heat).”

    Racing goes electric: At the track with Formula E, the first e-racing series
    Ars checks out the new all-electric racing car series on its first visit to the US.
    http://arstechnica.com/cars/2015/03/racing-goes-electric-at-the-track-with-formula-e-the-first-e-racing-series/

    Welcome to Formula E, the world’s first fully electric racing series. Miami is playing host to the first of two US rounds—the next being held in Long Beach, CA, on April 4—and it’s the fifth race in this ePrix’s inaugural season. Given we’ve got a bit of a thing about racing at Cars Technica, as well as an obvious interest in electric vehicles, we had to be on the ground in Miami to experience this for ourselves.

    The series kicked off in Beijing in September 2014, and this inaugural 11-round season ends in London this June. Each race takes place in a city center on a temporary street circuit, and the events are condensed into a single day. This both maximizes the spectacle for the fans in attendance and minimizes the disruption to everyone else in the city (with the road closures and so on). It’s one of many things we discovered Formula E does in contrast to the more traditional two- or three-day race meeting.

    The Miami track has been built on the streets surrounding the city’s NBA arena (and the small park that lies next to it).

    Largely, that skepticism is aimed at the cars Formula E is racing. For this first season, each of the ten teams is using identical Spark-Renault SRT_01Es, open wheel race cars that look somewhat similar to a Formula 1 or IndyCar.

    Behind the driver where you’d normally expect to find a fuel tank and internal combustion engine, there’s a 28 kWh lithium-ion battery supplied by the Williams F1 team. This sends up to 200 kW to the powertrain, an electric motor, and five-speed gearbox (supplied by McLaren, another F1 team).

    Both companies are rather proud of their contributions to the SRT_01E. Williams was constrained by a rulebook that insisted the battery couldn’t weigh more than 441 lbs (200 kg), and the design of the chassis also dictated its dimensions. Despite this, the company built a battery that actually exceeds the allowed energy storage and meets all the crash safety requirements.

    At 28 kWh, the SRT_01E’s batteries don’t store enough electricity to last a full race, and recharging takes almost an hour—far too long to be practical in a pit stop. What’s more, a decision was made to use the battery’s safety cell as part of the car’s structure, so they can’t just be swapped during a race (even though Williams had just such a system in development).

    The solution? Each Formula E driver needs two cars for the race, jumping from one to the other during a pit stop.

    The sound of an SRT_01E in motion really is quite unlike anything we’ve experienced at a racetrack in the past.
    the best approximation we can think of might be the Millennium Falcon

    As entertainment, the series has met its goal in the first season. The racing is exciting, and the single-day event format in city centers is a good recipe for a fun day out.

    Here’s hoping for great things from Formula E in the years to come.

    Finnish company hard goal: every third car dashboard

    In the growth-builder is selected Rightware, which reaches out into higher and higher. The company’s goal is that a couple of years to get to 30 per cent of new cars is its user interface technology.

    Finnish Venture Capital Association organized the competition the winner was chosen this year Rightware. It reported profits in connection with an agreement to already 14 premium car brand with.

    Rightware aim is that in 2017, 30 per cent of new cars used car screens, such as the instrument panel and center console, its interface technology. And the visions just limited to cars, because the business can also be extended, for example, smart home solutions, home appliances and consumer electronics.

    Toughening Up LPDDR4 and Parallel NOR Flash For Automotive
    Auto beats consumer market in memory growth
    http://www.eetimes.com/document.asp?doc_id=1326160&

    Micron Technologies Inc. has introduced two new families of high-speed low power, double data rate (LPDDR4) DRAM and parallel NOR flash memory products that push performance. Rather than rolling out new memory in desktop, laptops, and mobile devices, the company will debut its chips in the automotive market.

    The company’s G18 family of high performance flash NOR devices are capable of 266 Mbites/second transfer rates, which will make possible faster boot and code execution for higher density applications.

    “With consumers expecting smart phone connectivity in their car infotainment systems along with advanced new automotive features like driver assist systems, memory requirements in the connected car are increasing,” said Giorgio Scuro, general manager of Micron’s Automotive Division.

    So Micron is initially targeting the G18 parallel NOR Flash family at automotive applications that require fast, reliable code storage and execution in the millisecond range, such as the rear–view cameras in advanced driver-assist systems, which need fast boot speed for instant readiness.

    Asked about Nvidia’s plans for its GPU in embedded vision SoCs for Advanced Driver Assitance System (ADAS), Danny Shapiro, senior director of automotive, said Nvidia isn’t pushing GPU as a chip company. “We are offering car OEMs a complete system – both ‘cloud’ and a vehicle computer that can take advantage of neural networks.”

    A case in point is Nvidia’s DRIVE PX platform — based on the Tegra X1 processor — unveiled at the International Consumer Electronics Show earlier this year. The company describes Drive PX as a vehicle computer capable of using machine learning, saying that it will help cars not just sense but “interpret” the world around them.

    Conventional ADAS technology today can detect some objects, do basic classification, alert the driver, and in some cases, stop the vehicle. Drive PX goes to the “next level,” Nvidia likes to say. Shapiro noted that Drive PX now has the ability to differentiate “an ambulance from a delivery truck.”

    By leveraging deep learning, a car equipped with Drive PX, for example, can “get smarter and smarter, every hour and every mile it drives,” claimed Shapiro. Learning that takes place on the road feeds back into the data center and the car adds knowledge via periodic software updates, Shapiro said.

    Audi is the first company to announce plans to use the Drive PX in developing its future automotive self-piloting capabilities. Shapiro said Nvidia will be shipping Drive PX to its customers in May, this year.

    Big Blue to give car insurers IoT peeking powers
    New US$3bn business unit promises connected cloudy capers
    http://www.theregister.co.uk/2015/03/31/big_blue_to_give_car_insurers_iot_peeking_powers/

    IBM has announced it will spend US$ billion over four years on a new internet of things business unit.

    The company reckons the internet of things label now applies to all the the smart city stuff it did for water and traffic management applications in recent years. The idea seems to be to take that work, sprinkle on a little cloud and/or Watson analytics and deliver what IBM’s calling “an open platform to provide manufacturers with the ability to design and produce a new generation of connected devices that are better optimized for the IoT, and to help business leaders across industries create systems that better fuse enterprise and IoT data to inform decision-making.”

    Which sounds benign. The company’s plan to “introduce a cloud-based service that helps insurance companies extract insight from connected vehicles” may appear less so. IBM reckons this service “… will enable new, more dynamic pricing models and the delivery of services that can be highly customized to individual drivers,” but it’s not hard to imagine something going wrong with that.

    IBM’s announcement has the whiff of bandwagon-clambering while at the same time representing a new spin on the company’s current cloud analytics mantra. There’s mention of 2,000 people being dedicated to the IoT effort

    Elon Musk created nearly $1B in value today with a single tweet
    http://pando.com/2015/03/30/elon-musk-created-nearly-1b-in-value-today-with-a-single-tweet/

    So much for haters who like to dismiss the impact and growth of Twitter.

    Today the world – and particularly Wall Street – got a master class in the power of a few well placed words, when a single tweet by Tesla (and SpaceX) CEO Elon Musk cause the electric car maker’s stock to jump nearly 4 percent in just 10 minutes – adding a staggering $900 million to the company’s market cap in just 115 characters.

    What new information did Musk share to have such impact? The tweet was light on details, but heavy on hype and anticipation – just the kind of commentary that the SEC tends to frown upon.

    The tweet may have initially gone out to Musk’s 1.86 million followers, but the impact was far greater. By the end of the day, Musk’s message had been retweeted more than 4,700 times and favorited another 3,700, while eliciting thousands more responses.

    There may not be too many other execs that could drive the kind of instant stock rally as Musk by doing little more than circle a date on the calendar.

    DSI (Distributed Systems Interface)
    http://www.eetimes.com/author.asp?section_id=36&doc_id=1326167&page_number=3

    In response to an automotive requirement for a robust, fault-tolerant communication system for airbag crash sensor applications, a consortium of TRW, DENSO, and Freescale Semiconductor developed the DSI serial bus specification that includes power and signal over a single wire.

    DSI specification allows for enough local energy storage so that the system can withstand intermittent loss of main power.

    DSI version 2.5 includes error detection via a CRC (cyclic redundance check) of up to 8 bits, and frequency spreading for improved EMI performance. It’s a full-duplex master-slave system; the master communicates via a differential bus voltage signal while a slave responds by varying the current draw to indicate a logic high or low.

    Freescale offers both master and slave DSI devices that can communicate at up to 200 Kbps. The MC33781 Quad Bus Master communicates with a host microcontroller via SPI and controls up to 15 individually-addressable slave devices, connected in a daisy-chain configuration, on each of its four channels.

    DSI Consortium Home Page
    http://dsiconsortium.org/index.php

    The Distributed Systems Interface (DSI) is a flexible and powerful bus protocol designed to interconnect multiple remote sensor and actuator devices to a central control module. The principal target application for the network is automotive airbag systems.
