Abstract
An automatic constant-speed cruising control apparatus for a vehicle comprises a vehicle speed sensor for sensing a present vehicle speed; a command switch group; a controller including a memory for storing an desired cruising speed, a calculator for generating an actuator drive signal in response to the difference between the desired cruising speed and the present vehicle speed, a cancel controller, a resume controller, a transition controller, integration means for integrating duration time of the actuator drive signal during constant acceleration control by the resume controller, and decision means for detecting the present vehicle speed to approach the desired cruising speed; and an actuator for driving a throttle valve according to the actuator drive signal. The transition controller drives drastically in the closing direction of the throttle valve for the time calculated depending on the integral time obtained by the integration means when the present vehicle speed approaches the desired cruising speed.
