    摘要: A vehicle drive device includes a first rotating electrical machine, an input member, and an output member drivingly coupled to different rotating elements of a differential gear unit. A second rotating electrical machine is coupled to a different rotating element of the differential gear unit than the first rotating electrical machine. A control device detects an output rotation abrupt change where an absolute value of rotational acceleration of the output member is equal to or larger than a predetermined value, and, if the output rotation abrupt change state is detected where a rotational speed of the input rotating element is lower than a threshold value, the control device executes restriction avoidance where a rotational speed of the first rotating electrical machine is controlled so that the rotational speed of a input rotating element becomes equal to or higher than the threshold value.
