Abstract: A parking brake actuator generates and applies a braking force to a vehicle wheel in such a manner that the parking brake actuator converts a rotational motion of a screw member, which is rotated by an electric parking brake driving device, into a translatory motion and transmitting the converted translatory motion to a piston to push a brake pad toward a disc by the piston. The electric parking brake driving device includes an electric motor and a reduction gear mechanism which transmits driving force of the electric motor to the parking brake actuator. The reduction gear mechanism includes a gear body and a planetary gear mechanism, which is provided within the gear body and into which the driving force of the electric motor is inputted. A cushion rubber, which is compressible in the circumferential direction, is interposed between a ring gear of the planetary gear mechanism and the gear body.

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.
