An oil pump driving control device of a vehicle having a main oil pump () that is driven by a motor/generator () and produces a pump discharge oil to a first clutch (), a second clutch () and a belt-type continuously variable transmission () provided on a driving force transmission line. A hybrid control module () is provided in this FF hybrid vehicle. The hybrid control module () is configured to perform a control so that during vehicle stop, the lower an ATF oil temperature is, the more the pump driving energy to drive the main oil pump () is decreased. With this control, consumption energy during the vehicle stop can be reduced.

Vehicle oil pump driving control device

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.
