Abstract
A constant speed holding apparatus which, once a vehicle speed is set, maintains the cruise of the vehicle at constant speed by both variable speed control and throttle control. The difference between the set speed and actual speed is detected during vehicle cruise, and if the difference is smaller than a predetermined minute value, the variable speed ratio at the time of the detection is maintained by a correction means so that any possible speed vibration due to mutual interference between variable speed control and throttle control is effectively prevented.
