A control device for a hybrid vehicle is described which enables preventing a decrease in the efficiency of regeneration even when the revolution rate of an internal combustion engine is decreased during deceleration of the vehicle. The control device for a hybrid vehicle comprises an internal combustion engine and a motor connected in series with respect to each other, a torque converter which is connected to the rotational axis of the motor and which is provided with a lockup clutch, a transmission, a mechanical oil pump producing oil pressure for controllably operating the torque converter and the transmission, a motor-driven oil pump producing oil pressure for controllably operating the lockup clutch, and an ECU. The ECU operates the motor-driven oil pump depending on the deceleration state of the vehicle, and sets the lockup clutch in an engaged state. A method for operating the concerned control device is also described.
A control device for a hybrid vehicle comprising:
A method of controlling operation of a lockup clutch for a torque converter in a transmitting section of a hybrid vehicle in which wheels are driven via said torque converter by at least one of an internal combustion engine and a motor, comprising the steps of:
