ABSTRACT:
When the ABS control is executed by the ABS control portion, the vehicle brake control device calculates the first rotational speeds of the first and second motors necessary to achieve the corresponding pressure increase rates and calculates the second rotational speeds of the first and second motors as the upper limits caused by the unlocking pressure limits. Then the vehicle brake control device controls current values of the currents to be supplied to the first and second motors so that they are rotated in the rotational speeds obtained within a range from the first rotational speeds to the second rotational speeds.
