Abstract
A speed control system for a motor vehicle automatically controls a throttle valve so as to allow the vehicle to run at a desired velocity at all times. The system includes a laser radar for detecting a preceding vehicle and measuring the distance therefrom, and a control computer in which a proper distance responsive to a vehicle velocity is set. The control computer discriminates proximity to the preceding vehicle through change in the distance at a certain interval. When the distance exceeds the proper distance, the control computer reduces the desired velocity in case proximity to the preceding vehicle is discriminated at a plurality of times continuously and increases the desired velocity in case no such proximity is discriminated, and when the distance is below the proper distance, the computer decelerates the vehicle by directly controlling the throttle valve in the closing direction, allowing tracing running with the proper distance from the preceding vehicle.
