    摘要： A vehicle drive system configured with a dynamo within a case. The case is disposed on at least one axial side of the dynamo, and includes a wall portion overlapping the dynamo, which has a section that overlaps with the dynamo as viewed from the axial direction. The wall portion overlapping the dynamo includes a supply flow passage through which lubricating-cooling fluid flows, and which is formed with a first supply portion that supplies lubricating-cooling fluid to a rotor support bearing for the dynamo electric. The first supply portion includes a throttle portion whose flow passage cross-sectional area is small when compared to an upstream-side flow passage cross-sectional area in the flow direction of lubricating-cooling fluid. The supply flow passage includes a second supply portion that is a portion supplying lubricating-cooling fluid to the dynamo and higher than the first supply portion.

    摘要： A vehicle drive including an input coupled to an engine, an output coupled to wheels, an intermediate member between the input and output and coupled to a rotary electric machine, a friction engagement device between the input and intermediate member, and a control device. The control device, when starting the engine with the friction engagement device disengaged, engages the friction engagement device when a rotational speed difference between the input and intermediate member is equal to or less than a predetermined value; raises a rotational speed of the input using the rotary electric machine with the friction engagement device engaged to start the engine; and, when a rotational speed of the engine is equal to or more than a predetermined value, reduces an engagement pressure of the friction engagement device and the friction engagement device is returned to the engaged state when the rotational speed difference reaches a threshold.
