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 Announces Dual Motors, ‘Autopilot’ For the Model S
    http://tech.slashdot.org/story/14/10/10/129224/tesla-announces-dual-motors-autopilot-for-the-model-s

    Nine days after Elon Musk hinted about a new project, Tesla Motors has unveiled the P85D Sedan. This is Tesla’s latest car design, capable of feats not yet seen in electric vehicles. The four door luxury car is able to go from zero to 60 miles per hour in a mere 3.2 seconds, an acceleration similar to the McLaren F1 super car.

    The D models will also have a slightly greater range of 275 miles on a single charge, 10 miles more than the 85 and P85 cars.

    The Model D Is Tesla’s Most Powerful Car Ever, Plus Autopilot
    http://www.wired.com/2014/10/tesla-reveals-details-big-model-d-announcement/

    Tesla’s next car, the P85D, will have two motors and all-wheel drive. It will match the 3.2 second 0 to 60 mph time of the McLaren F1, one of the fastest cars ever made. And it will be even more efficient than the current, already terrific, Model S.

    “This car is nuts. It’s like taking off from a carrier deck. It’s just bananas,” said CEO Elon Musk, who unveiled the D at a crowded event, next door to the headquarters of the other company he helms, Space X.

    What’s especially impressive is that Tesla managed to improve the car’s efficiency and range, despite the added mass of the second motor.

    Autopilot

    In a move that most of the luxury auto market has already made, the car will offer active safety features like adaptive cruise control and the ability to read speed limit signs, stop itself if a crash is imminent, stay in its lane, and even park itself in a street spot or in your garage.

    These features are provided thanks to new hardware that will go into future Model S cars (and is already in every car produced in the past two weeks). Tesla is adding a radar that can see through fog and snow; a camera with image recognition capability to spot traffic signs and lights, as well as pedestrians; 360-degree ultrasonic sonar; and a system that combines all the data those produce with navigation, GPS, and real-time traffic systems.

    The net result will be a car that can be put on “autopilot,” if not fully autonomous mode. Tesla isn’t ready to make the jump quite yet, Musk said, since the safety system can’t be fully relied on, and regulations to handle self-driving cars have to be figured out. But, Musk said, if you fall asleep while driving, the car should be able to get you home safely. If you try to steer into danger, the wheel will resist.

    Owners will also be able to summon the car to pick them up autonomously, as long as they’re on private property, where DOT and other regulations don’t apply. “The car can do almost anything,” he said.

    Tesla Model S Auto Pilot Does Lane Changes For You
    http://jalopnik.com/tesla-model-s-auto-pilot-does-lane-changes-for-you-1644644652

    The “something else” at tonight’s Tesla event is Auto Pilot, a new system that combines a forward facing camera and 12 sensors that see 16 feet in every direction and provide a 360-degree view the surroundings. The camera does everything from seeing other cars to reading speed limit signs. Normal fare for luxury cars. Except it will also do a lane change for you just by pressing the turn signal stalk.

    Despite ‘D’ Disappointment, Tesla Still Matters
    http://www.eetimes.com/document.asp?doc_id=1324253&

    The long, speculation-drenched week that followed Elon Musk’s “unveil the D” tweet is finally over. Tesla Motors Thursday night (Oct. 9) announced an all-wheel-drive (awd) Model S with semi-autopilot features.

    The “D” stands for dual motor, while those who guessed it was “D” for “driverless” were just a little off the mark. With the D series, Tesla is offering, in essence, its own version of ADAS (advanced driving assistance system). Indeed, some featured in the D line are more like ADAS on steroids.

    After the announcement, some in the investment community were quick to judge, calling D a disappointment.

    Further, the continuing slippage in Model X deliveries is a big concern. Model X, unveiled in 2012, won’t get to reserved buyers until summer 2015. Model X, about which Musk bragged to Tesla shareholders in July, calling it “amazing car that will just blow people away,” is an all-electric vehicle, supposedly more stylish than a minivan, offering more performance than an SUV.

    Volvo Trucks to develop a technology that monitors the drivers of heavy vehicles on behalf of the blind spot, and more pedestrians and cyclists.

    Poor visibility is one of the most common causes of accidents involving heavy vehicles and other road users, Volvo Trucks’ statement says.

    Volvo in Gothenburg and Chalmers University of Technology in conjunction with the technology developed is called the Non-Hit Car and Truck. It sees the vehicle around the 360-degree area. Environmental describe the cameras will send the data to the sensors and warn too close to the pedestrians and cyclists.

    Also, Volvo’s competitor, the Japanese Honda has announced plans to create “crash free society”.

    United States Air Force, or the most advanced fighter F45 is equipped with six million lines of code. It is nothing compared to the most advanced in the car. S-Series Mercedes-Benz by lines of code is as high as 65 million.

    Mentor Graphics CEO Greg Hinckley told reporters yesterday in Oulu Mentor Forum in how the S-Merc describes the development of automotive electronics, anyway. – 40 per cent of such premium is the price of the car electronics.

    S Mercedes figures are also otherwise massive. Cabling is the base model 2.5 kilometers, featured mallis as much as 4.3 kilometers. CAN-systems is 73, LIN-bus, take advantage of the system 61.

    Tesla’s autopilot isn’t special (but it’s still cool)
    An important non-revolution for self-driving cars
    http://www.theverge.com/2014/10/17/6982289/tesla-autopilot-is-a-non-revolution-for-self-driving-cars

    “We’ve been able to accelerate autopilot and bring it to market faster than originally anticipated,” Elon Musk said to a gathered throng at Hawthorne Airport last week, the ex-Northrop facility in Southern California that both Tesla and sister company SpaceX call home. “It’s actually in production. In fact, every car coming off the line at Tesla at the factory has the autopilot hardware.”

    Musk has an outsized personality with a reputation for flair and hyperbole, and for the most part, he earns it: both Tesla and SpaceX have undertaken and delivered on profoundly large challenges that entire industries (and governments) have failed to overcome. And his preferred term of “autopilot” for the bundle of hardware and software installed on new Teslas isn’t inaccurate — the car can take control on highways, park itself in your garage at home, and intervene when it thinks you might be on a collision course.

    But for as many things as Tesla’s autopilot mode does, the one thing it doesn’t do is change the game. The stereotypical vision of a car of the future tooling around your neighborhood with a driver comfortably asleep at the wheel (or missing altogether) isn’t any closer to reality than it was before.

    Reflections on autonomy and anonymity (of cars and people)
    Blaine Bateman -October 15, 2014
    http://www.edn.com/electronics-blogs/the-connected-car/4436022/Reflections-on-autonomy-and-anonymity–of-cars-and-people-

    The State of California has a reputation for being early and often when it comes to legislating, well, pretty much everything. So it comes as no surprise that the state has laws on the books impacting autonomous vehicles. In 2012, State Senator Alex Padilla of California introduced SB-1298 which was passed into California Law on September 25, 2012. The law took effect on September 16 of this year; on the same day Audi USA issued a press release announcing they had received the first permit under the new law to operate autonomous vehicles on public roads.

    Not to be outdone, Mercedes USA announced two days later (Sept. 18) they had also received permission. On the same day, but over in Stuttgart, Daimler AG (Mercedes’ parent company) hosted a Symposium entitled “Connected driving and Data Protection” that, among other things, intended to further public debate on how autonomous vehicles fit into society.

    In related news, Bloomberg reported on October 1 that a German regulator had ordered Google to limit combining data in ways that reveal personal information, such as relationships or patterns of visiting certain locations. It isn’t much of a leap to see that connecting your car to the cloud could generate big data about your daily routine.

    we’ll see a transition from driver assistance to connected cars. Even using “connected” as the descriptive word is a large umbrella. The possibilities range from in-car hotspots (see the response, from OnStar to Ford’s SYNC), to vehicle to vehicle (V2V) communications, to drive-by-wire, to fully autonomous cars.

    For V2V applications, the hole in the roof is likely to be the location of the intra-vehicle connectivity solution. Why? While cars have radar, lidar, cameras, and other sensors in places like bumpers or mirrors, to form a large mesh network of cars on the road, the wireless solution needs to be in a location to provide high-reliability links. The roof gets the system line-of-sight to nearby vehicles in most situations, while other locations would be compromised in one or more directions.

    Consider a typical (proposed) V2V scenario: a mile ahead of you, traffic is slowing to a crawl on the highway.

    That brings us back to privacy, big data, and the law. If your car always knows where it is, is always connected to the Internet, and is carrying on conversations with other cars, what does that mean to you? Convenience, or the spectre of Big Brother?

    he National Highway Traffic Safety Administration put out a recall notice Monday for defective airbags and urged people whose cars are equipped with them to take action immediately.

    More than 4.7 million vehicles are involved in the recall. At least four people have died when inflator mechanisms ruptured on the air bags, spraying the passengers with metal fragments.

    The airbags are made by Takata and are in place in some Toyota, Honda, Mazda, BMW, Nissan and General Motors models.

    Audio bus technology takes on MOST, Ethernet AVB
    http://www.edn.com/electronics-products/other/4436299/Audio-bus-technology-takes-on-MOST–Ethernet-AVB?elq=06cdd3b281754377b105ebc401218960&elqCampaignId=19802

    Analog Devices (ADI) has developed an audio signal distribution system for automotive use that could emerge in some environments as a strong competitor to established infotainment bus systems like MOST and Ethernet AVB.

    It reads like the dream of an infotainment system designer: ADI’s Automotive Audio Bus (A2B) promises to reduce the weight of the cable loom by up to 75%, minimize connector size and replace bulky wiring systems through a simple unshielded twisted pair cable. Nevertheless, A2B transports high-quality audio signals over 32 discrete channels to any place in the car interior (well, at least as it is less than 10 meters away from the center stack).

    While already filed as a trademark in April 2013, ADI now has introduced the first real product for its Automotive Audio Bus. The AD2410 transceiver is a cost-effective audio transceiver, offering a bandwidth of 50 Mbps. It supports all popular audio sampling rates and enables daisy-chaining of multiple slave nodes. In contrast to most existing digital bus architectures, the system delay is deterministic. For these reasons, the AD2410 is suited for time-critical applications such as active noise cancellation, in-car communications and electronic microphone beam forming.

    Will the Google Car Turn Out To Be the Apple Newton of Automobiles?
    http://tech.slashdot.org/story/14/10/22/2130219/will-the-google-car-turn-out-to-be-the-apple-newton-of-automobiles

    The better question may be whether it will ever be ready for the road at all? The car has fewer capabilities than most people seem to be aware of.

    Driving in Circles
    The autonomous Google car may never actually happen.
    http://www.slate.com/articles/technology/technology/2014/10/google_self_driving_car_it_may_never_actually_happen.single.html

    A good technology demonstration so wows you with what the product can do that you might forget to ask about what it can’t. Case in point: Google’s self-driving car. There is a surprisingly long list of the things the car can’t do, like avoid potholes or operate in heavy rain or snow. Yet a consensus has emerged among many technologists, policymakers, and journalists that Google has essentially solved—or is on the verge of solving—all of the major issues involved with robotic driving. The Economist believes that “the technology seems likely to be ready before all the questions of regulation and liability have been sorted out.” The New York Times declared that “autonomous vehicles like the one Google is building will be able to pack roads more efficiently”—up to eight times so. Google co-founder Sergey Brin forecast in 2012 that self-driving cars would be ready in five years, and in May, said he still hoped that his original prediction would come true.

    But what Google is working on may instead result in the automotive equivalent of the Apple Newton, what one Web commenter called a “timid, skittish robot car whose inferior level of intelligence becomes a daily annoyance.” To be able to handle the everyday stresses and strains of the real driving world, the Google car will require a computer with a level of intelligence that machines won’t have for many years, if ever.

    It’s easy to understand the excitement about the Google car. The first two prototypes were heavily modified Prius and Lexus models; the most recent, a dome-shaped two-seater with a top speed of 25 mph, is entirely computer-controlled, lacking even a steering wheel.

    By most accounts, a demo ride in any of the Google cars is an astonishing thrill. It’s even more impressive when you recall that in a much-publicized test only a decade ago, robotic vehicles couldn’t finish even eight miles of a 150-mile course.

    The DARPA Grand Challenge: Ten Years Later
    http://www.darpa.mil/NewsEvents/Releases/2014/03/13.aspx

    At the break of dawn on March 13, 2004, 15 vehicles left a starting gate in the desert outside of Barstow, Calif., to make history in the DARPA Grand Challenge, a first-of-its-kind race to foster the development of self-driving ground vehicles. The immediate goal: autonomously navigate a 142-mile course that ran across the desert to Primm, Nev. The longer-term aim was to accelerate development of the technological foundations for autonomous vehicles that could ultimately substitute for men and women in hazardous military operations, such as supply convoys.

    The Grand Challenge was designed to reach beyond the traditional defense performer base and tap into the ingenuity of the wider research community. It was DARPA’s first major attempt to use a prize-based competition to attract novel performers and ideas and encourage collaboration across diverse fields.

    “That first competition created a community of innovators, engineers, students, programmers, off-road racers, backyard mechanics, inventors and dreamers who came together to make history by trying to solve a tough technical problem,”

    Although it isn’t easy to quantify the effects of these DARPA challenges on the development and deployment of autonomous vehicle technology, ten years later defense and commercial applications are proliferating. The rapid evolution of the technology and rules for how to deploy it are being driven by the information technology and automotive industries, academic and research institutions, the Defense Department and its contractors, and federal and state transportation agencies.

    DARPA expects that, like the original Grand Challenge before them, these challenges will encourage new waves of research and development that will spur continued innovation, encourage commercial investment, and lower the cost of advanced technologies.

    This is not the first such public demo – the CityMobil2 demonstration in Sardinia ran in August on a stretch of beachfront road blocked to cars but open to bicycles, service vehicles and pedestrians. Where the Sardinia project offered only a linear route, the Singapore project press release includes maps showing that the route is non-linear. Both projects have very low maximum driving speeds of 10km/hour.

    The Singapore project will also mix with pedestrians, but the area is closed to cars and bicycles.
