  • Patent number: 10023167
    Abstract: This electric braking device uses drive torque of an electric motor to push a friction member against a rotating member secured to a vehicle wheel and produce braking torque in the vehicle wheel. This device comprises a body power source for electric motor power supply secured to a body of the vehicle, and a vehicle wheel power source for electric motor power supply secured to the vehicle wheel. The body power source supplies power to the vehicle wheel power source via a first electric path, and the vehicle wheel power source supplies power to the electric motor via a second electric path. When braking torque is produced in the vehicle wheel, the electric motor is normally driven using the vehicle wheel power source. An electric braking device is thereby provided in which a power line electrically connecting the body side and the vehicle wheel side bends readily.

  • Patent number: 9975531
    Abstract: A vehicle brake control device includes an electric motor controlled based on a target energization amount calculated based on an operation amount (Bpa) of a braking operation member. Based on the operation amount (Bpa), it is determined whether or not an inertia compensation control for compensating for the influence of the inertia of a brake actuator is necessary. When the inertia compensation control is determined to be necessary, an inertia compensation energization amount for compensating for the influence of the inertia of the brake actuator is calculated based on a time-series pattern set in advance based on the maximum response of the brake actuator. Based on the inertia compensation energization amount, the target energization amount is calculated. The vehicle brake control device is thus able to generate a braking torque that appropriately compensates for the influence of the inertia of the entire device including the inertia of the electric motor.
