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: 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.

Abstract: Electric motor control is based on a target energization amount calculated using a braking operation member operation amount. A state quantity is acquired as an actual value, indicating an actual actuation state of a movable member located in a power transmission path from the electric motor to a friction member. Using the operation amount, it is determined whether or not inertia compensation control is necessary, which compensates for the inertia influence of a brake actuator during electric motor deceleration. “A target value corresponding to the actual value” is determined as a reference value, which is calculated based on the operation amount at a time when inertia compensation control is necessary. Based on the actual and reference values, “an inertia compensation energization amount for decreasing the target energization amount to compensate for the influence of inertia” is calculated, and the target energization amount is adjusted using the inertia compensation energization amount.
