摘要:
In a drive system, a first differential mechanism transmits engine rotation, a second differential mechanism connects the first differential mechanism with drive wheels, and a switching device changes a speed ratio of the first differential mechanism. The second differential mechanism has first, second, and third rotational elements, which connect respectively to the first differential mechanism, a first rotating machine, and a second rotating machine. In a first running condition, the vehicle runs using the second rotating machine as a power source, while differentially operating the first differential mechanism. In a second running condition, the vehicle runs using the second rotating machine as a power source, without differentially operating the first differential mechanism. A region in which the vehicle runs in the second running condition in the case where the engine cannot start by itself is larger than that in the case where the engine can start by itself.

A power transmission device includes: an engine; a rotary machine; and an oil pump connected to each of a rotary shaft of the engine and a rotary shaft of the rotary machine through a one-way clutch. The power transmission device is configured to allow the rotary machine to rotate at a rotational speed higher than the rotational speed corresponding to a speed of the engine and lower than the rotational speed corresponding to an idling speed of the engine at the time of startup of the engine.

A hybrid vehicle includes electrical storage devices, a charging device, a motor generator, a diode, an outlet and a relay. The first electrical storage device stores driving electric power. The charging device charges the first electrical storage device with the user of a power supply outside the vehicle. The motor generator has a power generation function. The second electrical storage device stores electric power that is generated by the motor generator. When electric power is output to a device outside the vehicle from the outlet, the relay limits electric power, which is output from the first electrical storage device, such that electric power stored in the second electrical storage device is output.

Provided is a control device of a vehicle, the vehicle having an electric motor and an engine. The control device includes an operating device and a controller. The operating device is configured to be selected a running capability of the vehicle. The controller configured to increase a running capability to be achieved using the electric motor alone, in a case where the vehicle travels using the electric motor alone according to the selected running capability, as compared with a case where the vehicle travels using the electric motor alone and the running capability is not selected.

A hybrid drive apparatus includes: a drive power source that includes an internal combustion engine, a first electric motor, and a second electric motor; a power transmission mechanism that includes a carrier, a sun gear, and a ring gear, and that is configured to rotate the output shaft of the internal combustion engine by the first electric motor; and plural bearings that each includes an outer ring member and an inner ring member fitted to the outer ring member through a rolling element, and that are provided apart from each other in an axial direction of the output shaft with the carrier being positioned between the bearings. An inner periphery of the outer ring member is positioned more inward in a radial direction of the ring gear relative to a meshing portion between inner teeth of the ring gear and outer teeth of one of the pinion gears.

In a lubrication structure of a differential gear unit, a case has a guide rib that extends over a certain area with respect to a rotation path of a head of a bolt when a ring gear rotates, and that protrudes out from the case toward the head of the bolt. Also, a through-hole that extends in a vertical direction is formed in an upper portion of a hollow supporting portion, and the guide rib has an oil reservoir that curves toward an upper end opening of the through-hole.
