摘要： An engagement force for engaging a first friction engagement element is set to be lower than an engagement force for establishing a predetermined shift stage with a second friction engagement element being engaged when a vehicle is stopped with an acceleration pedal not being operated and a brake pedal being operated under a forward driving range in an automatic transmission. The engagement force for the first friction engagement element is increased when a vehicle starts with the brake pedal released from the operated condition, and the engagement force for engaging the second friction engagement element is decreased when a relative rotational speed between a turbine wheel and a forward movement member becomes equal to or smaller than a predetermined rotational speed.

The controller means controls a locking-up hydraulic pressure in accordance with said hydraulic pressure control time schedule to be provided to a lock-up clutch that mechanically connects and disconnects a pump impeller of a torque converter of said automatic transmission connected to an engine and a turbine runner connected to transmission gears. The second memory stores a time schedule of engine revolution during a shift operation. The time schedule management means resets said hydraulic pressure control time schedule higher pressures than the former pressures in case if engine revolution exceeds said time schedule of engine revolution during the shift operation by a certain given limit.
