Abstract
A system and method assists the driver of a motor vehicle in preventing accidents or minimizing the effects of same. In one form, a television camera or other ranging device is mounted on a vehicle and scans the roadway ahead of the vehicle as the vehicle travels. Continuously generated video picture signals output by the camera are electronically processed and analyzed by a fuzzy-logic-based image analyzing computer mounted in the controlled vehicle, which generates control signals and applies them to control the operation of the accelerator, brake, and steering system of the vehicle in a coordinated way to attempt to avoid or lessen the effects of a collision. In a particular form, the decision computer may select the evasive action taken from a number of choices, depending on whether and where the detection device senses other vehicles and obstacles. Warning signals may also be generated.
