Abstract
A controller is provided so as to control, when an electric vehicle (EV) mode is selected, a belt clamping pressure on the basis of discharged oil from a main oil pump which is driven by a motor generator. The controller is provided for a hybrid vehicle and is configured to perform control such that when the vehicle is stopped in the EV mode and a creep cut condition which does not require creep torque from the motor generator is met, a first motor idling rotation speed is set as a motor rotation speed. When the vehicle is stopped in the EV mode and a standby learning control completes learning of a zero-point oil pressure command value, the controller reduces a rotation speed of the motor generator to a second motor idling rotation speed which is lower than the first motor idling rotation speed.
