Advanced Driver Assistance Systems: A Matter of Image

Posted June 22, 2014 12:00 AM by Engineering360 eNewsletter

Automobile electronics - and advanced driver assistance systems (ADAS) in particular - promise steady growth for image sensors. According to this survey article, ADAS sensors include visible-light and infrared (IR) image sensors, radio detection and ranging (radar), and light detection and ranging (lidar). The most advanced systems combine data from multiple sensor types (sensor fusion) for more accurate decision-making. Among the two broadest ADAS classifications are lane-departure warning systems, which alert the driver if the vehicle strays from the lane, and lane-keeping systems, which react automatically to bring the vehicle back into the lane.

I think lane departure warning systems are a good idea. It should set an alarm if the car changes lanes without the turn signal on. (Around here, a flashing light on the rear of the car usually indicates a loose bulb.) Lane keeping systems I would steer away from (pun intended). Thank you very much, I want to steer the car myself.

It's funny that the best sensors have always been the drivers, but since the advent of "smart" phones, they need help 'cause they are NOT PAYING ATTENTION!

Cool bling, but when it fails it is another story.

If you are lucky, such systems will fail hard, but what I have been finding is failures that are intermittent, failures even the dealer can't understand, and failures that are not even real (because the fault system is faulty).

This is with a 10 year old car technology. The last thing I want is another nanny system that will fail at some time in the vehicle's life and adds nothing of substantial value toward driving.

I have to agree with you. The smarter the cars get, the stupider the drivers get. The more crutches people have, the harder they fall when the crutches fail.
