Abstract
In a constant-speed cruising control system for a vehicle in which the throttle opening is feedback-controlled according to the difference between the actual vehicle speed and a desired vehicle speed so that the actual vehicle speed matches the desired vehicle speed, the vehicle speed is constantly detected when it increases in response to a driver's command, and the throttle valve is controlled so that the throttle opening converges on a target throttle opening which is predetermined according to the vehicle speed. The target throttle opening is corrected according to the running condition of the vehicle so that the vehicle speed is increased at a constant acceleration irrespective of the running condition of the vehicle.
