ABSTRACT:
An electric oil pump control system for a hybrid vehicle which has an engine and a first electric motor as driving sources; a hydraulic automatic transmission connected between the engine and drive wheels of the vehicle; an electric oil pump for generating an oil pressure necessary for performing gear change of the transmission. The hybrid vehicle can run by at least one of the engine and the first electric motor in accordance with a driving state of the vehicle. The control system has a control device for driving the electric oil pump so as to generate an oil pressure supplied to the hydraulic automatic transmission, wherein the control device drives the electric oil pump when the hybrid vehicle runs with the engine and the electric oil pump which are stopped, in accordance with a predetermined condition by which it is determined that the electric oil pump should be driven.
