Abstract:
A vehicle control system includes: an engine; a power transmission device that transmits power from the engine to drive wheel; a mechanical pump that supplies oil for operating the power transmission device to the power transmission device by driving of the engine; and an electric pump that supplies the oil to the power transmission device by driving of a motor. The vehicle control system is capable of executing stopped economy running control for stopping the engine when a vehicle is stopped, and travel economy running control for stopping the engine while the vehicle is traveling. During the execution of the stopped economy running control, learning control is executed whereby a control value for controlling the oil pressure is updated such that the actual oil pressure generated by the electric pump is converged to a target value. During the execution of the travel economy running control the learning control is prohibited.
