Abstract:
A vehicular power-transmission control system comprising:an engine, which is under a fuel-supply termination control; a power-transmission mechanism, which transmits a rotational driving force from said engine to wheels; and a frictionally engaging element, which controls a transmission of the rotational driving force in said power-transmission mechanism; wherein: said control system, when a throttle of said engine is closed and when the vehicle has started decelerating, executes a vehicle-in-deceleration control to terminate a fuel supply at an elapse of a predetermined time from the starting of the deceleration; and in said vehicle-in-deceleration control, when said throttle is detected to have closed, an engaging force of said frictionally engaging element is set to reduce a torque transmitted through said frictionally engaging element, and after the termination of the fuel supply to said engine, said engaging force is gradually increased to bring said frictionally engaging element gradually into engagement.
