摘要： Based on a difference (”Fb) 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 ”Fb, if the ”Fb 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 ”Fb 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.
