  • Publication number: 20200198602
    Abstract: A control device for a vehicle including a first brake device that applies a braking force to vehicle wheels in response to a driver's operation of a brake, a second brake device that applies a braking force to the vehicle wheels through an electric actuator when a shifting operation position is switched to a parking position, and a parking lock mechanism that stops rotation of the vehicle wheels by stopping rotation of a parking gear interlocking with the vehicle wheels when the shifting operation position is switched to the parking position. The control device includes an electronic control unit configured to maintain an operating state of the first brake device until the braking force is applied to the vehicle wheels by the second brake device when the shifting operation position is switched to the parking position after the first brake device has been operated by the driver.

  • Patent number: 10670138
    Abstract: A vehicle drive device that includes a case forming a first accommodating space that accommodates a speed change device and a second accommodating space that accommodates a rotary electric machine; an storage that is disposed under the first accommodating space and stores oil; a hydraulic pump including a suction that suctions the oil from the oil storage; a first oil passage that supplies the oil discharged by the hydraulic pump to the speed change device as hydraulic oil; a second oil passage that supplies the oil discharged by the hydraulic pump to the rotary electric machine as cooling oil; and a third oil passage that returns the oil supplied to the rotary electric machine, from the second accommodating space to the oil storage, by allowing the oil to flow in a direction from the second accommodating space toward the first accommodating space.

  • Patent number: 10193414
    Abstract: 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.
