The software for self-driving cars, or even for full collision-avoidance systems, may be years away, but the sensors are already here. Today automobiles are studded with sensors. Analysts predict that collision avoidance will be the feature that propels electronic-sensor systems into new automobiles. Currently, Mercedes-Benz S-class vehicles are equipped with 24-GHz radar that can provide emergency braking when accidents become inevitable. In addition, radar-based adaptive cruise control is found in the BMW 3 series, the Volkswagen Passat, several Mitsubishi models, and Mercedes-Benz and Toyota cars. The next applications of sensors and video cameras, according to Frost & Sullivan, will be object-classification services that warn of vehicles in the driver's blind spot and accidental lane departures, and that provide heads-up night vision.
