Abstract
An auto-cruise controller to control the throttle angle of an engine so that the actual vehicle speed is equal to the target vehicle speed. In the controller, the pressure control of a lock-up clutch of an automatic transmission is conducted based on an amount of control of the lock-up pressure calculated corresponding to the traveling conditions of the vehicle when the throttle is fully closed, and when the vehicle is descending a slope during the auto-cruise control.
