Today, it's hard to imagine an automobile without electronic control. Microcontrollers for engines, transmissions, airbags, brakes, and stability control systems are taken for granted. We expect them to be down there, communicating across databases with such names as CAN, LIN, and FlexRay.
But automotive electronic controls haven't remained stagnant. Today's intelligent navigation systems can watch traffic. Vehicles can parallel-park themselves. Manufacturers are incorporating adaptive cruise control, lane-keeping, and camera-based collision avoidance.
Engineers are keeping an eye on the distant future, too. In the agricultural world, tractors can now drive themselves. Experimental street vehicles have done the same in DARPA's Grand Challenge.
In this slideshow, we've corralled developments in automotive electronics, from the advances in collision avoidance to the far-reaching technologies of autonomous vehicles.

Using a vehicle-to-grid strategy in the future, electric car batteries will be able to dump energy back onto the grid when utilities need help. A grid interface on a prototype Ford Escape plug-in hybrid allows users to control the time of re-charging and check the costs of electricity on the grid at any given moment.

To keep up with our Chevy Volt coverage, go to Drive for Innovation and follow the cross-country journey of EE Life editorial director, Brian Fuller. On his trip, sponsored by Avnet Express, Fuller is driving a Volt across America to interview engineers.
Cars do indeed have to many processors and controllers. Multicore will certainly not improve things or reduce the number of them, it will only serve to increase both complexity and price, particularly price to repair them. Likewise, reliability will dive as more functions get mired in poorly written code.
Remember a few years back, when the car was going to have one giant control module and everything was going to be multiplexed, and the car would only have 3 wires? Now, primarily in the search for "product differentiation", every chunk of hardware that does anything spots it's own microcontroller. Worse, each of these little gimmics is vying for a bit of driver attention. The next goal is full internet connectivity and content, with location prompted advertising. Full time distraction coming to a vehicle, even dispite driving being a full time task.
The problem with all of the automation is that it is not able to deal with the exception correctly, every time, always. Drivers often can respond correctly, if they are not distracted, and if they are allowed to respond correctly. BUt the programmed systems can never be right all the time, because they can't ever be programmed that way.
The solution is not better programming, it is getting rid of much of the automation and allowing the driver to be in control. The system can record just what the driver did, so as to either clear him or to nail him. Of course this reduces privacy, but on the roads we could use some accountability, not privacy.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
Biomedical engineering is one of the fastest growing engineering fields; from medical devices and pharmaceuticals to more cutting-edge areas like tissue, genetic, and neural engineering, US biomedical engineers (BMEs) boast salaries nearly double the annual mean wage and have faster than average job growth.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
