Abstract
A vehicle that improves the accuracy of wheel stopping determination including a stopping determination unit that calculates stopping determination time by multiplying the pulse width of a wheel speed pulse immediately before a non-output time, for which no wheel speed pulse is output from a wheel speed sensor, by 2+1, or a corrected time which is corrected on the basis of the stopping determination time is set as a threshold value for determining stopping of wheels. Thus, the time corresponding to the pulse width of the wheel speed pulse takes into consideration the deceleration and traveling distance of the vehicle, thereby obtaining an optimum threshold value for determining the stopping of the wheels.
