<p>Provided is a vehicle capable of improving the precision of a stop decision of wheels. Either a stop-deciding time period that is the product of the pulse width of the wheel speed pulses just before the no-output time period, for which no wheel speed pulse is outputted from a wheel speed sensor (3), and (21/2 + 1), or a correction time period, which is corrected on the basis of the stop-deciding time period, is used as a threshold value for deciding the stop of the wheels. The wheel speed pulses, which are outputted just before the no-output time period, are outputted when the wheels are substantially stopped. Thus, the time period corresponding to that pulse width is multiplied by the constant (21/2 + 1) that is the constant considering the deceleration and the mileage of the vehicle, to produce the optimum threshold value for deciding the wheel stop. By deciding the wheel stop on the basis of the stop-deciding time period or the correction time period, therefore, the wheel stop can be promptly and precisely decided. Thus, it is possible to improve the precision of the stop decision of the wheels.</p> |
