Claim Text:
1. A control device for a hybrid vehicle, the hybrid vehicle comprising: an engine and a motor as a vehicle drive source; a first clutch arranged between the engine and the motor in a drive torque transmission mechanism from the vehicle drive source to drive wheels to vary a transmission torque capacity between the engine and the motor; and a second clutch arranged between the motor and the drive wheels to vary a transmission torque capacity between the motor and the drive wheels, the control device comprising: an engine start control part that performs engine start control to start the engine from an EV mode, in which the hybrid vehicle is driven by drive force of the motor with engagement of the second clutch, by increasing a rotation speed of the motor, while allowing slippage of the second clutch, and bringing the first clutch into slip engagement; and a drive torque upper limit setting part that sets a drive torque upper limit value based on an added motor rotation speed, which is given by adding an additional rotation speed to the rotation speed of the motor, as an upper limit of a drive torque transmitted to the drive wheels in the EV mode and as an upper limit of the transmission torque capacity of the second clutch.
