摘要： An electric motor is controlled based on a target energization amount that is calculated based on an operation amount of a braking operation member. A state quantity is acquired as an actual value (Sva), which indicates an actual actuation state of a movable member located in a power transmission path from the electric motor to a friction member. Based on the operation amount, it is determined whether or not inertia compensation control is necessary, which compensates for the influence of inertia of a brake actuator during deceleration of the electric motor. "A target value (Svt) corresponding to the actual value" is determined as a reference value (ref), which is calculated based on the operation amount at a time point when it is determined that the inertia compensation control is necessary. Based on the actual value and the reference value, "an inertia compensation energization amount (Ikt) for decreasing the target energization amount to compensate for the influence of inertia" is calculated, and the target energization amount is adjusted based on the inertia compensation energization amount (Ikt). Accordingly, there can be provided a vehicle brake control device, which generates a braking torque by the electric motor and which can properly compensate for the influence of inertia of the entire device during deceleration of the electric motor.

摘要： Based on a difference (ΔFb) between a target value (Fbt) of a force of a friction member for pressing a brake disc and an actual value (Fba) thereof, a feedback energization amount (Ipt) is calculated by using a proportional gain that is smaller than an ultimate sensitivity gain. Based on the ΔFb, if the ΔFb falls within a fluctuation range of a torque ripple, a first compensation energization amount (Ibt) is calculated by using a proportional gain that is larger than the ultimate sensitivity gain, and if the ΔFb falls outside of the fluctuation range, the first compensation energization amount (Ibt) is calculated so as to be constant. A second compensation energization amount (Ift) is calculated based on a calculation characteristic that is preset based on a torque fluctuation over a predetermined range of a position of an electric motor and based on an actual position of the electric motor. An indication energization amount (Ist) calculated in accordance with the Fbt is adjusted by the Ipt, the Ibt, and the Ift so that a target energization amount (Imt) is calculated. With this, it is possible to provide a vehicle brake control device which is configured to generate a braking torque by the electric motor and is capable of compensating for effects of a torque ripple of the electric motor to improve control accuracy for the braking torque.

摘要： In this device, an electric motor is 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 (FLj←1 or FLk←1), an inertia compensation energization amount (Ijt, Ikt) for compensating for the influence of the inertia of the brake actuator is calculated based on a time-series pattern (CHj, CHk) set in advance based on the maximum response of the brake actuator. Based on the inertia compensation energization amount (Ijt, Ikt), the target energization amount is calculated. Consequently, it is possible to provide a vehicle brake control device which causes an electric motor to generate a braking torque and which is capable of appropriately compensating for the influence of the inertia of the entire device including the inertia of the electric motor.

摘要： Based on a difference between a target value and an actual value of a force of a friction member to press a brake disc, feedback control over the pressing force is executed. As the actual value, a detection value (Fba) of the pressing force itself is not used, but a "limit pressing force (Fbs) obtained by placing a limitation on a temporal change amount of the Fba based on of a limit value (Lmt)" is used. The limit value (Lmt) is set based on an electric motor speed (dMkt, dMka), a wheel speed (Vwa), and a temporal change amount (”Tmp) of a temperature of the friction member. The Lmt is set so as to increase as the dMkt (dMka) increases and the temporal change amount (”Tmp) of the temperature increases, and so as to also increase as the wheel speed (Vwa) decreases. Thus, in a vehicle brake control device configured to generate a braking torque by an electric motor, even when a rotating member (brake disc) is deformed, braking torque control can be appropriately executed without accelerating a fluctuation of a braking torque on the wheel.
