System for automatically controlling vehicle speed

摘要

In a system and method for automatically controlling a vehicle's speed, the rate of change of the inter-vehicle distance per predetermined unit of time is calculated from the detected inter-vehicle distance between the controlled vehicle and a preceding vehicle, a basic safe inter-vehicle distance is corrected according to the calculated rate of change of the inter-vehicle distance per predetermined time, and the vehicle speed is controlled according to the difference between the corrected safe inter-vehicle distance and the detected inter-vehicle distance.
