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.”

    Driving Display Startup Navdy Raises $20M to Start Commercial Production

    Seeking to end the dangerous juggle many smartphone-wielding drivers do when navigating, reading email, texting and calling contacts, Navdy Inc. created a gadget that projects information from smartphones onto car windshields.

    The startup, which quickly gained traction last year from investors and early adopters preordering its $299 gadget, has now closed a $20 million funding round. The infusion will be used to hire more engineers and move beyond the first production run and begin commercial manufacturing of the 5 inch-by-4 inch projectors later this year.

    “If you look down for four seconds while going 60 miles per hour, you’ve just driven a football field blind. I’ve had those same moments during stop-and-go traffic as well,” said Navdy Founder and CEO Doug Simpson of the impetus for founding the startup in 2012.

    Mr. Simpson said he wasn’t looking to raise a round just yet. He had closed a $6.5 million seed round in August last year along with $6 million in preorders for some 17,000 of the devices.

    Navdy is the latest in growing class of hardware startup to pique investor interest.

    Navdy’s service allows users to control apps with voice commands, similar to the way GoogleNow and Siri operate. Navdy also has a camera that recognizes gesture controls, so users can do things like swipe left to answer a call or swipe right to dismiss a notification.

    Electric cars won’t spread even with rapid chargers: Toyota engineer

    YOKOHAMA, Japan (Reuters) – Battery-powered electric vehicles don’t have a practical future as a long-range alternative to conventional cars even if technological breakthroughs allow them to be charged quickly, a top engineer at Toyota Motor Corp said on Thursday.

    Electric vehicle (EV) supporters have touted developing high-speed charging technology as the way forward for cars like Nissan Motor Co’s Leaf. But Yoshikazu Tanaka, chief engineer of Toyota’s hydrogen fuel-cell car Mirai, said that would guzzle so much energy at once as to defeat the purpose of the EV as an ecologically sound form of transportation.

    “If you were to charge a car in 12 minutes for a range of 500 km (310 miles), for example, you’re probably using up electricity required to power 1,000 houses,”

    “That totally goes against the need to stabilize electricity use on the grid.”

    “Toyota isn’t denying the benefits of EVs,” Tanaka said. “But we think the best way to use them is to charge them at night (to avoid peak power consumption hours), and use them for short distances during the day.”

    Instead, Toyota says hydrogen fuel-cell vehicles (FCVs) offer the most promising zero-emission alternative to conventional cars since they have a similar driving range and refueling time.

    How Tesla Disrupts Infotainment Supply Chain

    Automaker Tesla moves away from Tier-One designers on infotainment and does its own design work.

    Instead of relying on traditional tier-1 suppliers to design and make the Model S’ infotainment system, Tesla did much of the design work itself while outsourcing the production to contract manufacturing firms.

    A $69,900 plus price tag is a lot to pay for a car, but Tesla tries to give a lot in return.

    Automotive Chip Reliability: A Matter of Design Methods

    Up to 90% of all innovations today are generated through novel applications of semiconductors and electronic circuits. In the project Resilient Integrated Systems (RESIST), ten partners jointly strengthen the role of nanoelectronic components as the key to future developments. The research focuses on design processes for microchips and next-gen systems that will meet even higher requirements in terms of quality and reliability.

    The goal of the RESIST activities is designing particularly reliable high-performance components that at the same time contribute to one of the automotive industry’s overarching aims: Reducing fuel consumption and CO2 emission.

    To meet customer expectations and legislative specifications, future vehicle generations and their electronic components will have to exhibit extremely high resilience and reliability; at the same time their physical dimensions need to be reduced to enable design engineers to implement more functions and new applications. This expectations translates into the requirement of higher performance at lower power consumption.

    For these reasons, the RESIST partners will research how such high-performance microelectronic and nanoelectronics components can be designed to achieve maximum robustness and reliability.

    Mini’s Working on Augmented Reality Driving Goggles

    Steampunk enthusiasts and Morgan owners aside, driving goggles are a thing of the past, rendered obsolete by the advent of the windshield. Yet Mini sees a bright future in which we all wear goggles … as head-up displays.

    The once-British brand, now owned by BMW, says its customers value style and performance above all, which makes us wonder if it really thinks people will embrace augmented reality goggles. Nevertheless, Mini believes such eyewear is the best way of populating the driver’s field of vision with helpful information.

    And here’s the thing: It actually works pretty well.

    The latest Mini hardtop comes with camera-based active safety features like pedestrian detection and collision avoidance (automatically applying the brakes if necessary). It’s also got a head-up display that projects information like speed and navigation directions onto the windshield. HUDs are a common and popular feature on luxury cars these days, one Mini wants to take off the windshield and put right in front of its customers’ eyeballs.

    Keeping Your Car Safe From Electronic Thieves

    Let me explain: In recent months, there has been a slew of mysterious car break-ins in my Los Feliz neighborhood in Los Angeles. What’s odd is that there have been no signs of forced entry. There are no pools of broken glass on the pavement and no scratches on the doors from jimmied locks.

    But these break-ins seem to happen only to cars that use remote keyless systems, which replace traditional keys with wireless fobs.

    I watched as the girl, who was dressed in a baggy T-shirt and jeans, hopped off her bike and pulled out a small black device from her backpack. She then reached down, opened the door and climbed into my car.

    When the police arrived, they didn’t have much of an answer.

    I called Toyota, but they didn’t know, either (or at least the public relations employee didn’t know).

    The Toronto Police Service issued a news release last Thursday warning that thieves “may have access to electronic devices which can compromise” a vehicle’s security system. But the police did not specify what that “device” actually was.

    Thieves have been breaking into and stealing cars with the help of electronic gadgets for several years now. Jalopnik, the car blog, has written about a “secret device”used to unlock cars. And dozens of other websites have told stories about burglars hacking into cars.

    A more likely answer came from the National Insurance Crime Bureau, a trade group for auto insurers and lenders, which issued a warning last month about a “mystery device” that can emulate a key. In one YouTube video, the group compiled surveillance footage that showed thieves using the gadget to open doors with ease.

    When I told him my story, he knew immediately what had happened. The teenagers, he said, likely got into the car using a relatively simple and inexpensive device called a “power amplifier.”

    What’s The Secret Device Thieves In California Are Using To Break Into Cars?

    Back before the sophisticated car security systems, the “devices” often used to steal cars had the incredible hidden abilities to also hang clothes safely off the floor or drive nails into innocent sheets of plywood. Modern car thieves have been spotted new generation of devices that seem to be able to unlock many cars instantly by simply being held against the vehicle.

    Based on what’s happening, I think we can do some speculating. I think it’s safe to say the device is an RF transmitter operating in the 300-400 Mhz range, and using a brute-force method to send the remote-entry codes to the car. I’m guessing the reason for the direct contact with the car is because the device has a very low-power transmitter

    Got a BMW? Thicko thieves can EASILY NICK IT with $30 box
    Your flash motor – gone in 180 seconds

    BMWs and other high-end cars are being stolen by unskilled criminals using a $30 tool developed by hackers to pwn the onboard security systems. The new tool is capable of reprogramming a blank key, and allows non-techie car thieves to steal a vehicle within two or three minutes or less.

    On-board diagnostics (OBD) bypass tools are being shipped from China and Eastern Europe in kit form with instructions and blank keys

    Would-be car thieves need to grab the transmission between a valid key fob and a car before reprogramming a blank key, which can then be used to either open the car or start it, via the OBD system.

    “Crooks only need to monitor a person using the key or interrogate the key fob to get enough information to decipher the key,”

    Weak cryptography combined with a security-through-obscurity approach in the OBD specification allows the tactic to succeed.

    The German car giant added that the issue was not limited to BMW, and promised to help mitigate the attack, in a statement published last Wednesday.

    BMW prides itself on its vehicle security systems and all BMWs meet all UK and global security standards. Our engineers and technicians review all aspects of our vehicles constantly, including security systems.

    Fraud Files: The Mystery Device

    It’s a growing trend lately and it has many law enforcement agencies scratching their heads. Thieves are using high-tech electronic devices to break through the keyless-entry systems that lock up modern cars.

    This story is excerpted and adapted from Elon Musk: Tesla, SpaceX, and the Quest for a Fantastic Future, due out May 19 from Ecco, an imprint of HarperCollins.

    On May 8, 2013, Tesla Motors shocked just about everyone by posting its first-ever quarterly profit, reporting higher-than-expected demand for its Model S electric sedan. That moment marked the beginning of a turnaround for Elon Musk’s tumultuous automaker. The next year would see the Model S win most of the automotive industry’s major awards and Tesla’s share price rise roughly fivefold, to more than $200. The 2013 profit announcement was fortuitous. Just weeks before, Tesla had been on the verge of bankruptcy.

    Mini Augmented Vision is a cool concept trying to solve Google Glass failings
    Hands-on: BMW and Qualcomm make a convincing case cars are the best place to start AR.

    The first iteration of Google Glass was a valuable experiment. It started out as a neat concept that enjoyed a lot of hype, but it exposed a lot of problems that practical augmented reality still faces—battery life, processing power, not to mention the huge social implications of carrying a camera on your face in public. But BMW Group and Qualcomm think they have an answer to those problems, and the answer involves making the use case for augmented reality a little more narrow.

    Enter Mini Augmented Vision. The system is a pair of glasses that integrate with BMW Group’s Mini cars to project helpful information in a low-impact way over the wearer’s immediate field of vision. Rather than try to be everything a smartphone is—but for your face—Augmented Vision is simply “the next iteration of the head-up display,” a representative from Mini told Ars. The Research and Technology branch of BMW Group has been working for years on ways to improve heads-up displays, which were born from airplane technology, giving fighter pilots critical information without them having to look down at their instruments (and away from the sky).

    Automakers To Gearheads: Stop Repairing Cars

    Automakers are supporting provisions in copyright law that could prohibit home mechanics and car enthusiasts from repairing and modifying their own vehicles.

The dispute arises from a section of the Digital Millennium Copyright Act

    Automakers to gearheads: Stop repairing cars
    Car Companies Say Home Repairs Are ‘Legally Problematic,’ Seek Copyright Restrictions

    Automakers are supporting provisions in copyright law that could prohibit home mechanics and car enthusiasts from repairing and modifying their own vehicles.

    In comments filed with a federal agency that will determine whether tinkering with a car constitutes a copyright violation, OEMs and their main lobbying organization say cars have become too complex and dangerous for consumers and third parties to handle.

    Allowing them to continue to fix their cars has become “legally problematic,” according to a written statement from the Auto Alliance, the main lobbying arm of automakers.

    Every three years, the office holds hearings on whether certain activities should be exempt from the DMCA’s section 1201, which governs technological measures that protect copyrighted work. The Electronic Frontier Foundation, a nonprofit organization that advocates for individual rights in the digital world, has asked the office to ensure that enthusiasts can continue working on cars by providing exemptions that would give them the right to access necessary car components.

    Complex Software, Increased Risk

    Industry concerns are mounting that modifying these ECUs and the software coding that runs them could lead to vulnerabilities in vehicle safety and cyber security. Imagine an amateur makes a coding mistake that causes brakes to fail and a car crash ensues. Furthermore, automakers say these modifications could render cars non-compliant with environmental laws that regulate emissions.

    But exemptions from the DMCA don’t give third parties the right to infringe upon existing copyrights. Nor does an exemption mean consumers don’t have to abide by other laws and rules that govern vehicles passed by the National Highway Traffic Administration, Environmental Protection Agency or U.S. Patent and Trade Office.

    “It’s not a new thing to be able to repair and modify cars,” said Kit Walsh, a staff attorney with the Electronic Frontier Foundation. “It’s actually a new thing to keep people from doing it. There are these specialized agencies that govern what vehicles can lawfully be used for on the road, and they have not seen fit to stop them from repairing cars.”

    Aftermarket suppliers and home enthusiasts have been modifying ECUs for years without dire consequences. By tweaking the ECU codes, a process sometimes known as “chipping,” they’ve boosted horsepower, improved fuel efficiency, established performance limits for teen drivers and enhanced countless other features. These innovations have contributed to a “decades-old tradition of mechanical curiosity and self-reliance,” according to the EFF.

    GM: Telematics Industry Threatened

    For their part, manufacturers say they’re more concerned about potential losses than new revenue streams. Tinkering with the ECUs can void a car owner’s warranty, but automakers remain concerned with their liability if third parties make changes that could result in physical or financial harm. They noted unsavory mechanics could easily manipulate odometers, and make cars appear to have fewer miles on them than they actually do, a problem for unsuspecting used-car buyers.

    Automakers: We Know Our Cars Better

    Manufacturers and their lobbyists have submitted comments on six of the 27 proposals. The specific topics cover: unlocking mobile connectivity devices, unlocking consumer machines, jailbreaking all-purpose mobile computing devices, vehicle software diagnosis repair and modification, and software security and safety research.

    Tesla Isn’t an Automaker. It’s a Battery Company

    Tesla is admired for building the cars of the future. But it’s not really a car company. It’s a battery company that happens to make electric cars.

    At least, that’s the trajectory suggested by the news that Tesla will soon sell mega-batteries for homes and electric utility companies. CEO Elon Musk mentioned the possibility during an earnings call last February, and the plan was reportedly confirmed in an investor letter revealed yesterday. The official announcement is set to come next week.

    Selling batteries for homes, businesses, and utilities may seem like a departure for a car company. But for Tesla, it makes perfect sense. An electric car is only as green as the electrical grid that powers it. And if Tesla’s batteries become widespread, they could help utilities take better advantage of inconsistent renewable energy sources like wind and solar. As demand for renewables rises, whether through regulatory mandate or consumer desire, so would utilities’ demand for batteries that could help maintain a consistent flow—a demand Tesla is well-positioned to meet.

    Renewable power can come in fits and stops, depending on whether the wind is blowing and if the sun is shining, but the supply doesn’t always come at the exact same time as demand.

    Tesla’s move into the electrical utility market isn’t exactly novel says Sam Jaffe

    There are already dozens of companies offering battery packs for utility companies. But he says Tesla’s move is a validation of the market, and its scale will make it a major player.

    “In 10 years the grid will be cleaner, less expensive to maintain, and more reliable,” Jaffe says. “And that will be thanks to energy storage technology.”

    Tesla’s first expected foray beyond cars also highlights that the company’s battery manufacturing capacity may soon be its strongest asset.

    Google almost bought Tesla, according to new book

    Did you hear the one about a giant Silicon Valley company possibly buying Tesla?

    No, we’re not talking about Apple. We’re talking Google. Elon Musk and Larry Page shook on a deal that would have sold Tesla Motors to Google in 2013, says an upcoming book titled “Elon Musk: Tesla, SpaceX, and the Quest for a Fantastic Future” by Ashlee Vance.

    A couple of years ago, according to an excerpt from the book, the electric-car maker was on the verge of bankruptcy as it struggled to turn Model S pre-orders into sales.

    Tesla was looking for a lifeline, and CEO Musk turned to his friend, Google CEO Page, in March 2013. The deal that both parties discussed would have been worth $11 billion: $6 billion for the sale of the company, and $5 billion in capital for factory expansions.

    But something happened while negotiations were under way.

    in May 2013 the company reported a quarterly profit for the first time. Shares spiked. Tesla was in the money. So we know the way that story ended: Google did not gobble up Tesla.

    DLP chipset widens head-up display field of view

    Combining the imaging qualities of DLP (digital light processing) technology with automotive-grade reliability, the DLP3000-Q1 chipset from Texas Instruments enables head-up displays with a field of view of up to 12 degrees—one of the widest in the industry. It also provides high brightness, color, and contrast levels, bringing the flexibility and color accuracy of TI’s DLP Cinema DMD (digital micromirror device) to automotive windshields.

    The chipset comprises a DLP 0.3-in. WVGA digital micromirror device and a DLPC120 controller. A head-up display with such a wide field of view, as enabled by the DLP3000-Q1 chipset, allows augmented-reality elements, such as navigational indicators and real-time landmark details, to be displayed in the driver’s line of sight with a depth perception of 2 to 20 meters ahead.

    Ruggedized Tire Pressure Sensor Raises Bar
    Freescale Ups Ante in MEMS

    Tire pressure monitoring is now mandated by the governments of many countries around the world, making passenger cars and light trucks the biggest market for microelectromechanical systems (MEMS) that go inside the tire to monitor pressure and transmit it wirelessly to the dashboard of the driver.

    The government mandates are for the safety of consumers, but big commercial trucks and heavy machinery are exempted from these requirements, assumedly because professional drivers know better than to drive on deflated tires. However, many truckers — studies have found — adjust their tire pressure depending on the load they are carrying and sometimes intensionally deflate them slightly even though that degrades vehicle fuel efficiency. As a result, recent studies have shown that truck and heavy equipment fleet managers could reap significant savings by using MEMS tire pressure monitors.

    Freescale says it already has the world’s smallest MEMS tire pressure monitor for consumer vehicles, but now its upping the ante by offering the world’s highest pressure sensor for heavy trucks, buses and construction vehicles.

    Its system-in-package (SiP) also contains a two-axis accelerometer, an S08 8-bit processor with 512 bytes of RAM, 16-kbytes of flash (8k for Freescale library, 8k for applications), dedicated state machines for reduced power consumption, six general-purpose input/output (GPIO) ports — including two analog-to-digital (A/D) inputs — a low-frequency (125-kHz) receiver for programming user-defined functions and making periodic resets, and a high-frequency (315-to-434 MHz) RF transmitter supporting rolling encryption to issue warnings to the fleet manager and to read out a “prognosis” of each tire’s condition.

    The built-in accelerometer turns off the device when the vehicle is sitting still, but can also record the acceleration while in motion and also includes a temperature sensor to include in the correlations.

    New demands on DC-link power capacitors

    Following the trends in power electronics both automotive and industry applications need compact, reliable and cost effective components to reach the major targets increased power density and miniaturisation. Key technologies like fast switching semiconductors are already successful used in the market today.

    Since electronic components and its characteristics become more and more complex, design solutions have to be found on system level and in addition, the interaction of active and passive devices needs to be understood in detail. Especially during semiconductor switching, the DC-link capacitor as part of the commutation loop has a lasting effect on the behaviour and efficiency of the application. Different power electronic designs use low inductive assemblies of semiconductors and DC-link capacitors to lower the voltage overshoot during turn-off [4]. In most cases, system designers have to deal with capacitors of big volume and large commutation loops. The new capacitor technology “CeraLink™” which is described in this paper and was introduced earlier in [1] and [2], shows high capacitance density as well as a very low self-inductance to keep the commutation loop inductance as low as possible.

    DC-link capacitors are used in most power converters to stabilize the DC-link voltage by balancing the interim difference between the input source and the output load. The voltage ripple needs to be minimised to avoid electrical stress to the source and semiconductors as well as to comply with EMI requirements.

    To a large extent, the package of a motor inverter is driven by the DC-link capacitor size [3]. Therefore high capacitance density is a major key parameter to decrease the inverter volume and to increase the power density. Together with a high current handling capability, a low self-inductance and an optimized connection technique, a compact DC-Link should be achieved.

    What if electric cars suck dry the electrical network?

    Environmentally rapid spread of electric cars would be a great thing. But what happens to the grid if it is after the working day is connected to the same area tens or hundreds of cars to charge. The new software helps electrical operators.

    The German Fraunhofer Institute and its ADT unit (Advanced System Technology) researchers have developed software that shows you how many electric cars network can be connected to each area. App shows graphically the kind of low-voltage network load at any given moment lasts.

    Charging electric car draws in the network of up to 22 kilowatts of power. Household electricity networks is not intended for such a load. Modern networks do not actually need very many cars to achieving its limits.

    Germany substation typically supplies power to approximately 150 households.

    The researchers developed a program that allows up to millions of charging models by simulating network space 1000-10000 possible scenario. This simulation allows the network to quickly and sufficiently precise picture of how many rechargeable cars can still connect to it.

    Electric cars suck up to 140kW case, Tesla Supercharger. Normal fast chargers are capable of a max. 50kW power scores.

    [Jay] turns over a new Leaf, scores batteries

    [Jay] got a pretty good deal on a low milage Nissan Leaf battery. Unfortunately, it came wrapped in a wrecked Nissan Leaf. There are more and more electric cars on the road each year, and that means there are more cars coming off the road as well due to accidents. Electric cars are specifically designed to protect their batteries, so as we’ve seen before with Tesla vehicles, a salvage car often will still contain a serviceable battery pack. [Jay] used this knowledge to his advantage, and walks us through his experience buying, testing, and dismantling Hoja, his very own salvage Leaf.

    Now that the battery was known to be good, [Jay] set about liberating it from its crushed Leaf cocoon.

    Topic Teardown: Connected Cars’ Pros & Cons

    When it comes to potential threats posed by connectivity, security experts and industry analysts are no longer mincing their words. Unauthorized access or remote hijacking of a vehicle might be only a theoretical risk for today’s cars. But in the connected car of the future, it’s a distinct, real-world threat.

    “But those of us who have been around the block know” the industry’s drive for higher integration will eventually take over. Vendors want to cut cost, Williams said. “We’ve seen [the trend for integration] happen in airplanes, medical devices and other connected system designs.” As a result, he cautioned, “Many of the features and controls will be hosted by one computer, and those functions — traditionally separated by physical knobs and air gaps — are being replaced by software.”

    Once that happens, a hacker who gets into a trivial system like the car radio could seize control of the brakes, or any other system, he explained. At that point, the risk of connected cars no longer hypothetical.
