Abstract
A novel constant-speed drive system for automotive vehicles is disclosed, in which in response to an instruction for constant-speed drive while the vehicle is under acceleration, it is decided whether the vehicle acceleration at that particular time is higher than a predetermined value, and in accordance with the result of this decision, the change rate of the opening of the throttle valve is determined by use of an equation in which the value of a factor is set accordingly. In the case where the acceleration is comparatively high, the value of the factor may be changed to improve the responsiveness of the change rate of the opening of the throttle valve with the change in vehicle speed, thus making it possible to fully prevent the overshoot of the running vehicle speed.
