Abstract
When it is detected that a wheel speed vFL of at least one specific wheel WFL is nearly equal to zero but wheel speeds vFR, vRL, vRR of the other wheels WFR, WRL, WRR are not nearly equal to zero, the apparatus judges that the wheel speed vFL of the specific wheel WFL is abnormal, but cancels the abnormality judgment in a stuck state even if the wheel speed vFL of the specific wheel WFL was judged as being abnormal.
