Abstract
A system for automatically controlling vehicle speed calculates the relative speed between the subject vehicle and another preceding vehicle on the basis of the intervehicle distance detected by an intervehicle distance detector. One of a number of relative speed values derived with reference to different sampling periods is selected according to the magnitude of one of the relative speed values so that a highly accurate and fast responsive system for controlling the vehicle speed can be achieved on the basis of the vehicle speed, intervehicle distance, and selected relative speed.
