Abstract
A vehicle travel control device includes a plurality of wheel speed detection devices and a control unit. A plurality of wheel speed detection devices detects the wheel speed of each of the plurality of wheels. The control unit performs vehicle travel control (anti-skid control) based on the wheel speed detected by the wheel speed detection device. The control unit determines whether the wheel speed of the first wheel is abnormal based on the relationship between the wheel speed of the first wheel with the highest wheel speed and the wheel speed of the second wheel with the second highest wheel speed. Abnormality determination is performed to determine whether there is. When the vehicle is braking, the control unit does not make an abnormality determination when the wheel speed increase rate of the first wheel is less than the increase rate reference value.
