  • Publication number: 20230271507
    Abstract: A vehicle includes: a plurality of wheels; a plurality of rotary electric machines, each configured to generate a driving force or a braking force for one of the plurality of wheels independently from other rotary electric machines; a power storage device configured to exchange electric power with the plurality of rotating electric machines; a processor configured to calculate a required torque of each of the plurality of wheels; a rotational speed detecting sensor configured to detect a rotational speed of each of the plurality of wheels; and a controller configured to calculate a power distribution ratio that is a distribution ratio of electrical power from the power storage device to the plurality of rotating electric machines based on the required torque of each of the plurality of wheels and the rotational speed of each of the plurality of wheels.

  • Patent number: 9752676
    Abstract: A hybrid vehicle includes an internal combustion engine, a first motor, a second motor, a first planetary gear mechanism, a second planetary gear mechanism, a battery, and an electronic control unit. The first planetary gear mechanism includes a first rotating element, a second rotating element, and a third rotating element. The internal combustion engine is coupled to the second rotating element. The second planetary gear mechanism includes a fourth rotating element, a fifth rotating element, and a sixth rotating element. A brake is connected to the fifth rotating element. The electronic control unit is configured to turn on the brake at a time of high-vehicle-speed ignition-off of the hybrid vehicle such that the fifth rotating element is in a rotation stop state. The high-vehicle-speed ignition-off is that an ignition is off while the hybrid vehicle is traveling at a predetermined vehicle speed or higher while operating the internal combustion engine.
