摘要： An electric motor is controlled based on a target energization amount calculated based on an operation amount of a braking operation member. Based on the operation amount, 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 compensating for the influence of the inertia of the brake actuator is calculated using a time-series pattern set in advance based on the maximum response of the brake actuator. Using the inertia compensation energization amount, the target energization amount is calculated. The vehicle brake control device causes an electric motor to generate a braking torque and appropriately compensates for the influence of the inertia of the entire device including the inertia of the electric motor.

摘要： A vehicle includes a regenerative generator on a front wheel. A braking control device includes an actuator that applies a front wheel torque and a rear wheel torque, and a controller that individually adjusts the front wheel torque and the rear wheel torque. The controller is configured to determine the front wheel torque and the rear wheel torque to zero when a regenerative braking force Fg generated by the regenerative generator has not reached a maximum regenerative force Fx which is a generatable maximum value. On the other hand, the controller is configured to increase the rear wheel torque from zero before increasing the front wheel torque from zero when the regenerative braking force Fg reaches the maximum regenerative force Fx.

摘要： A brake control device adjusts a front wheel braking hydraulic pressure of front wheel cylinders provided on front wheels of a vehicle and a rear wheel braking hydraulic pressure of rear wheel cylinders provided on rear wheels of the vehicle. The brake control device includes a hydraulic pressure generating unit configured to adjust a hydraulic pressure generated by an electric motor to an adjusted hydraulic pressure and apply the adjusted hydraulic pressure as the rear wheel braking hydraulic pressure and a hydraulic pressure correcting unit configured to adjust to decrease the adjusted hydraulic pressure to be a corrected hydraulic pressure, and apply the corrected hydraulic pressure as the front wheel braking hydraulic pressure.

摘要： 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.

摘要： 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.
