Abstract
When the vehicle decelerates on the ascending slope, a required brake axle torque is calculated in accordance with vehicle deceleration, so that the swinging back is suppressed. At start timing after that, initial and final values of the required brake axle torque and a correction duration are determined. During the correction duration from the start timing, the required brake axle torque is decreased from the initial value to the final value. Then, based on change in a detected vehicular speed at or before a time which is a last moment of a period in which the detected vehicular speed detected based on detection signals of the wheel speed sensors are equal to or larger than a minimum detectable vehicular speed, a stop time at which an actual vehicle speed becomes zero is estimated, a period from the start time to the stop time is identified as the correction duration.
