1. A hybrid vehicle drive control system for a hybrid vehicle which comprises a drive system including an engine, a motor, a first clutch disposed between the engine and the motor, a second clutch disposed between the engine and a drive wheel, and operative, upon receipt of an engine start request, to engage the first clutch to thereby start the engine using a torque of the motor, the control hybrid vehicle drive system comprising:
a second clutch control unit programmed to conduct a second clutch control of the second clutch to disconnect a torque transmission path between the motor and the drive wheel upon the engine start request; a motor rotational speed control unit programmed to reduce a motor rotational speed through a motor rotational speed reduction control of the motor while the torque transmission path between the motor and the drive wheel is disconnected; an engine start control unit programmed to engage the first clutch to start the engine using the torque of the motor while the motor rotational speed is reduced, and to fully engage the second clutch after complete combustion of the engine; and a shift control unit programmed to conclude a downshift of a transmission, during a time from starting the engine to a time of full engagement of the second clutch in the torque transmission path between the motor and the drive wheel being disconnected. |
