    Abstract: A motor-driven compressor includes an inverter device. The inverter device includes a common mode choke coil. The common mode choke coil includes an annular core, two windings wound around the core, and an annular conductor that covers the two windings. The conductor is divided into a first metal plate and a second metal plate, which are combined to form an annular shape such that induced current flows in a circumferential direction of the conductor so as to hinder changes in leakage magnetic flux from the core. The second metal plate is thermally connected to the housing. The first metal plate is thermally connected to the second metal plate. At least one of an electrical resistance value or a thermal resistance value in a current path of the induced current is lower in the second metal plate than in the first metal plate.

  • Patent number: 11945431
    Abstract: A vehicle control apparatus includes a braking controller individually controlling braking forces of braking devices for left and right front and rear wheels, a side collision detector detecting a side collision against a vehicle, and a yaw behavior detector detecting yaw behavior of a vehicle body. If the yaw behavior detected after the side collision is such that a rear of the vehicle body shifts away from a collision side relative to a front thereof, the braking controller executes yaw amplification control to cause the braking device for the collision-side front wheel to generate a braking force larger than the remaining wheels. If the detected yaw behavior is such that the front shifts away from the collision side relative to the rear, the braking controller executes the yaw amplification control to cause the braking device for the collision-side rear wheel to generate a braking force larger than the remaining wheels.
