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.

Hybrid drive device

A hybrid driving apparatus includes an engine configured to output a rotation driving force to an output shaft; an input shaft configured to rotate in association with rotation of driving wheels of a vehicle; a clutch that is provided between the output shaft and the input shaft to disengageably connect the output shaft and the input shaft; a clutch actuator configured to operate the clutch; a motor generator configured to rotate in association with rotation of the input shaft; a rust formation determining unit configured to determine whether there is a possibility of a rust formation on the clutch; and a rust formation suppressing unit configured to operate the clutch actuator in a case where the rust formation determining unit determines that there is the possibility of the rust formation on the clutch.
