Abstract: An automatic method for preventing wheel skidding during braking and acceleration is disclosed, in which an instantaneous rotational wheel speed is sensed and an instantaneous absolute speed variation is calculated therefrom. During braking, the brake is released automatically when rotational speed either reduces so that speed variation is greater than a predetermined maximum permissible value, or when rotational speed approaches zero with the vehicle still moving. The brake is applied during braking when rotational speed increases to a predetermined time-varying value after brake release. During acceleration, the brake is applied when rotational speed increases so that speed variation is greater than the aforementioned maximum permissible value, and is released when rotational speed falls to a predetermined time-varying value after the brake application. The brake remains unaffected when speed variation is less than the maximum permissible value.
