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.

Abstract: A braking control device drives an electric motor based on a command pressing force corresponding to the required wheel braking force, and presses a friction member against a rotation member fixed to the wheel to generate a wheel braking force. The braking control device includes: a sensor for detecting wheel speed; a sensor for detecting the actual pressing force applied by the friction member; and a controller for calculating the target pressing force based on the command pressing force, and controlling the motor so that the target and actual pressing forces match. The controller calculates wheel slip state quantity based on the wheel speed, and executes, based on the slip state quantity, slip suppression control for reducing the degree of wheel slippage. Based on the actual pressing force at the start of the slip suppression control, the controller reduces the command pressing force and calculates the target pressing force.

Abstract: This electric braking device for a vehicle imparts to the wheels of the vehicle a braking torque in accordance with the output of an electric motor. A vehicle body-side electronic control unit calculates a command value for the output of the electric motor on the basis of the amount of operation performed on a braking operation member. A wheel-side electronic control unit adjusts the output of the electric motor on the basis of the command value. The vehicle body-side electronic control unit calculates the vehicle body speed on the basis of the wheel speed. The wheel-side electronic control unit adjusts the output of the electric motor so as to prevent an increase in slippage of the wheels on the basis of the vehicle body speed and the wheel speed.

Abstract: In a vehicle brake control device for generating rear wheel braking torque by an electric motor, “slip suppression control of the rear wheel” for reducing rear wheel braking torque by controlling the electric motor is executed based on a slip state quantity of the rear wheel. Further, “sudden-stop control” for rapidly stopping electric motor rotation motion is executed based on a slip state quantity of a front wheel. The sudden-stop control is executed when rear wheel slip suppression control is not being executed. As the sudden-stop control, “control for changing an energization amount of the electric motor stepwise to an energization limit value set in advance corresponding to a deceleration direction of the electric motor” may be executed. Accordingly, it is possible to suppress excessive rear wheel slip due to inertia influences or the like of the electric motor when execution of the rear wheel slip suppression control is started.
