PURPOSE:To prevent the occurrence of a speed change shock caused by improper feedback control by stopping the feedback control of a transient oil pressure in the initial stage of an inertia phase. CONSTITUTION:In a zone in which the rotating speed of a rotary member started to change for speed change (the initial stage of an inertia phase) according to a turbine rotation signal 99 and a vehicle speed signal 82, an ECU 84 stops the feedback control of transient oil pressure by an oil pressure control circuit 86, while starting the feedback control after the rate of change of rotating speed of an input shaft 22A is stabilized. As a result, it can be prevented that the transient oil pressure is suddenly increased due to feedback correction in the initial stage of the inertia phase, resulting in increase in the torque capacity of a clutch to suddenly change the torque of an output shaft 70. |
