Abstract
A cruise control system for vehicles uses a video camera to follow a vehicle driving ahead at a constant distance and speed on a highway. The system detects the distance to a vehicle and a relative speed to set the upper and lower limitations for the distance and the speed. The system controls a speed of the vehicle in accordance with the comparisons of the detected distance and speed with the limitations.
