Abstract:
Provided is a control device for a hybrid vehicle, capable of suppressing a drive torque variation during engine start control. The hybrid vehicle has an engine (Eng) and a motor/generator (MG). The control device has: an engine start control part that performs engine start control to start the engine (Eng) from an EV mode by increasing a motor rotation speed of the motor/generator (MG), while allowing slippage of a second clutch (CL2), and bringing a first clutch (CL1) into slip engagement; and a drive torque upper limit setting part (600) that sets a drive torque upper limit value (Tdrlim) in the EV mode based on an added motor rotation speed (Nad), which is given by adding an additional rotation speed (N+) to the motor rotation speed (Nmot), as an upper limit of a drive torque transmitted to drive wheels through the second clutch CL2.
