摘要： A power transmission apparatus includes a first electric motor, a power split mechanism, a second electric motor, a case, a support wall, and a breather mechanism. The case accommodates the first electric motor, the power split mechanism, and the second electric motor. The support wall is provided between the power split mechanism and the second electric motor. The breather mechanism is located in a rotational angle range that is at least equal to 90 degrees and is smaller than 180 degrees. The breather mechanism has a through hole and a breather chamber. The breather chamber is provided at a case inner side end of the through hole and is opened in a direction that does not oppose a virtual surface that passes through the rotational axis at a rotational angle of 90 degrees of the second electric motor.

摘要： In a non-forward range, the same gear position as a forward first gear position is established in a stepped transmission. A hydraulic controller includes a second linear solenoid valve and third linear solenoid valve that respectively supply hydraulic pressure to a second clutch and first brake, and a selector valve that is provided in an oil passage upstream of the second and third linear solenoid valves and that switches between a state where hydraulic pressure is supplied to the oil passage and a state where supply of hydraulic pressure is cut off. When the non-forward range is set or when a vehicle is moving backward, the selector valve cuts off supply of hydraulic pressure to the oil passage. Thus, when there is a failure in the second or third linear solenoid valve, it is possible to suitably establish a gear position wherein the vehicle is not allowed to move backward.

摘要： A driving force transmitting device includes a case, an electric motor, and a gearbox. The electric motor includes an output shaft. The gearbox includes a spur gear that rotates coaxially with the output shaft. The case includes a partition wall, a first accommodating chamber accommodating the electric motor, and a second accommodating chamber that accommodates a second driven gear. The partition separates the first accommodating chamber and the second accommodating chamber from each other. The partition wall includes a connecting hole that connects the first accommodating chamber and the second accommodating chamber to each other. The connecting hole is located on one direction side in relation to the central axis of the output shaft. At least part of the connecting hole overlaps with the spur gear when viewed in a direction along the central axis.

摘要： A control device performs a control process such that when there is a request in a series/parallel mode to switch the current mode to a parallel mode, and the current speed ratio also has a value faster than a Lo rotation synchronization speed ratio, the control device performs the step of switching the running mode to the parallel mode via a series mode with asynchronous switching, whereas when the current speed ratio has a value slower than the Lo rotation synchronization speed ratio, the control device performs the step of switching the running mode to the parallel mode via the series mode with synchronous switching.

摘要： A tolerance ring is arranged between an output-side rotary shaft and a rotor shaft. For this reason, even when looseness in a spline fitting portion of the output-side rotary shaft and rotor shaft is not filled, both the output-side rotary shaft and the rotor shaft are held by the tolerance ring so as not to rattle. Therefore, it is possible to reduce tooth hammer noise that occurs in the spline fitting portion.

摘要： A control system is for a vehicle that includes an internal combustion engine. The control system includes an electronic control unit. The electronic control unit is configured to limit an output of the internal combustion engine when the electronic control unit determines that the vehicle runs in an unmanned state, such that the output of the internal combustion engine is lower the vehicle runs in the unmanned state than when the vehicle runs in a manned state.

摘要： A manual unlocking device for a parking lock mechanism includes an operation lever that rotates when the parking lock mechanism is switched from a locked state to an unlocked state. The operation lever is arranged outside an occupant space of a vehicle cabin and is configured that a tool can be coupled to a rotation center thereof from the occupant space. The manual unlocking device for the parking lock mechanism is configured to switch the parking lock mechanism from the locked state to the unlocked state by integral rotation of the operation lever with the tool when the tool, which is coupled to the operation lever, rotates in a state where the tool is arranged on the rotation center of the operation lever.

Therefore, it is possible to reduce tooth hammer noise that occurs in the spline fitting portion. An output-side rotary shaft has oil passages for supplying lubricating oil to a tolerance ring. Lubricating oil is forcibly supplied through these oil passages to an annular space in which a tolerance ring is accommodated.
