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.
