Abstract
A control system for a hybrid vehicle configured to limit a thermal damage to a starting clutch without generating a shock. The control system is applied to a vehicle in which a prime mover includes an engine, a first motor, and a second motor. In the vehicle, the first motor is connected to the engine, and a first clutch and a second clutch are disposed between the engine and drive wheels. A controller executes a transient slip control to cause the second clutch to slip while bringing the slipping first clutch into complete engagement if a temperature of the first clutch is high. If an engine speed is changed during execution of the transient slip control, the first motor generates a collection torque to suppress the change in the engine speed.
