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.

I have to agree with Alex about the trend of loading up modern vehicles with too much electronics, especially for the average consumer. I have a pretty new car loaded with GPS, rear-view camera, built-in bluetooth, etc. For the life of me, I can't figure out how to use all of this stuff and forget about trusting the camera for backing up--no can do.
I can't even imagine relying on all the sensors and other electronics involved in automatic parallel parking or waking up the driver in the event they fall asleep at the wheel. While there's definitely a role for modern technology, at what point is it overkill, over complicated, and more of a detriment in terms of driver distraction?
I used to think of a car as a mechanical system with some electronics. In the past six months, it's clicked into my head that the modern automobile is actually an electronics platform, with (usually) an internal combustion engine as a component (sitting in the front like a refrigerator sits in the kitchen), though not necessarily an ICE; it could be a battery pack. Or a fuel cell (well, not really, that's not happening, though that's actually what I believe to be the most promising alternative technology). I guess my point, even though I'm an EE, is I think maybe we've hit a point where there's TOO much electronics in the modern car.
The Industrial Internet of Things may be going off the deep end in connecting everything on the plant floor. Some machines, bearings, or conveyors simply donít need to be monitored -- even if they can be.
Wind turbines already are imposing structures that stretch high into the sky, but an engineering graduate student at the University of Notre Dame wants to make them even taller to reduce energy costs and improve efficiency.
