1. Technical Field
The present invention relates to a control device for a hybrid vehicle which has an engine and an electric motor as a driving source with a first engagement element interposed between the engine and the motor engine while second engagement element interposed between the motor and a driving wheel.
2. Related Art
In such a hybrid vehicle having a first engagement element between the engine and the motor and having a second engagement element between the motor and the driving wheel, the second engagement element is protected by suppressing excessive heat generation when the load in a driving force transmission system is large. A system is known (see Patent Document 1, for example), in which, when the load in the driving force transmission system is equal to a predetermined value or more, the first engagement element CL1 is released with the engine operating while the second engagement element CL2 is slip-engaged so that the motor is held at a rotation speed lower than the engine rotation speed.
