Abstract:
Provided is a vehicle skid control device that avoids a skid erroneous judgment in a high revolution range of a motor. The vehicle skid control device detects the number of revolutions of the motor. When the number of revolutions of the motor is equal to or larger than a predetermined threshold value Nm, the vehicle skid control device prohibits a skid judgment. When the number of revolutions of the motor is smaller than the predetermined threshold value Nm, the vehicle skid control device permits the skid judgment. When the number of revolutions of the motor is equal to or larger than the threshold value Nm, the skid judgment is prohibited. Accordingly, it is possible to avoid the skid erroneous judgment in the high revolution range with the number of revolutions equal to or larger than Nm.
