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.

Control device for hybrid vehicle

A management system is provided for managing a hybrid vehicle having an engine and a motor/generator as power sources. The management system includes an acquisition unit and an area identifying unit. The acquisition unit acquires engine operating information from a plurality of vehicles, during the operation of the motor/generator. The engine operating information includes a moving distance or an engine operating time from the start of to the stop of the engine, and an engine operating position indicating the point at which the engine is operating. The area identifying unit identifies on map data an engine start-up suppressing area in which the start of the engine is suppressed based on the engine operating information.
