Abstract:
1. A control device for a hybrid vehicle drive apparatus, wherein the hybrid vehicle drive apparatus comprises an electrically controlled differential portion including a differential mechanism, connected to an engine in a drive-force transmissive state, whose differential state is controlled with controlling an operating state of a first electric motor, a second electric motor connected to a power transmitting path extending from the differential mechanism to drive wheels, and a power interrupting section forming part of the power transmitting path and operative to interrupt the same; the differential mechanism includes a differential-action limiting device enabling the differential action of the differential mechanism to be limited; and the control device is operative to cause the differential-action limiting device to limit the differential action of the differential mechanism, when the power transmitting path is interrupted by the power interrupting section during a vehicle running, and a rotation speed of a rotary element, present on the power transmitting path rotatably, exceeds a given rotary-element rotation speed determining value; and when the power transmitting path is interrupted by the power interrupting section during the vehicle running, and the rotation speed of the rotary element exceeds the given rotary-element rotation speed determining value, the control device is operative to execute at least one of a drive control for driving the first electric motor so as to lower the rotation speed, a fuel supply stop control for stopping or limiting a fuel supply to the engine, and a fuel regulating-valve opening control for limiting an opening of a regulating valve for regulating intake air quantity being supplied to the engine.
