ABSTRACT:
A vehicle brake control device determines a first duty factor required to achieve a stable rotational speed of motors and a second duty factor required to achieve a change rate of a target wheel cylinder pressure. The vehicle brake control device selects the larger one of the determined duty factors as a for-use motor duty factor to be used in outputting currents to the motors. Therefore, with the stable rotational speed and the change rate of the target wheel cylinder pressure, it is possible to achieve quick response to a request for braking made by a driver while suppressing the electric energy consumption of the motors.
