Abstract

A hybrid drive device in which an input shaft is connected to an engine, an output shaft is connected to wheels, and a wheel drive motor is connected between the input shaft and the output shaft. In the hybrid device, a friction engagement element that is provided between the input shaft and the output shaft and of which transfer torque is controllable. A control device controls the friction engagement element. The control device reduces the transfer torque of the friction engagement element during engine starting in a predetermined low temperature environment or during travel on a bad road, compared to the transfer torque of the friction engagement element in an engaged state.
