Abstract
Providing a control apparatus for a vehicular drive system, which permits economical and easy reduction of generation of an abnormal sound upon starting of an engine in a running state of a vehicle. The control apparatus includes on-engine-starting differential limiting means for commanding a differential limiting clutch to limit differential rotary motion between front and rear drive wheels, in advance of automatic starting of an engine under the control of automatic engine starting control means. Accordingly, the limitation of the differential rotary motion between the front and the rear drive wheels by the differential limiting clutch ensures the starting of the engine without backlash which exists in the power transmitting path between the engine and the front and rear drive wheels, thereby permitting economical and easy reduction of generation of the abnormal sound upon starting of the engine in a running state of the vehicle.
