Disclosed herein are embodiments of a control apparatus for a hybrid vehicle that is capable of suppressing overheating of the second clutch. Control is switched between engine-used slip drive control and motor drive control on a basis of a temperature of the second clutch. Control methods for a hybrid vehicle are also disclosed.

Control apparatus of a hybrid vehicle and method for controlling the same

A control apparatus for a hybrid vehicle that is capable of suppressing overheating of the second clutch is taught herein. Control is switched between engine-used slip drive control and motor drive control on a basis of a vehicle load such as weight or a road incline gradient. Control methods for hybrid vehicles are also disclosed.

A starting device has a friction element arranged between an engine and wheels for transmitting torque between them. The engagement and disengagement of the element is shifted by press force outputted from a press force applier, which is controlled by a control unit. The control unit includes a creep demand degree judging means judging a driver's creep demand degree for starting a motor vehicle after substantial stop of the vehicle with applying brake force to the wheels and outputs a creep demand degree signal, a creep time setting means setting creep time based on the creep demand degree signal and outputs a creep time signal, and a creep torque producing means producing creep torque by controlling the press force to obtain a slipping state of the element for a period determined based on the creep time signal.
