ABSTRACT:
A system and method for automatically controlling a vehicle speed to a desired cruising speed applicable to vehicles in which a basic manipulated variable corresponding, for instance, to an operation time of either of acceleration or deceleration valve in an actuator for actuating an engine throttle valve of a vehicle in which the system is mounted toward the acceleration or deceleration direction which is derived on the basis of the vehicle speed and target cruising speed so that the vehicle speed coincides with the desired target cruising speed is corrected according to a transfer function of a response to the opening angle of the throttle valve to the manipulated variable. The response of the throttle valve to a change in the manipulated variable is measured and the transfer function is computed on the basis of the measured response to compensate for vehicle variations and aging effects.
