摘要：An automatic method for preventing wheel skidding during braking andacceleration is disclosed, in which an instantaneous rotational wheel speed is sensed andan instantaneous absolute speed variation is calculated therefrom. During braking, thebrake is released automatically when rotational speed either reduces so that speedvariation is greater than a predetermined maximum permissible value, or when rotationalspeed approaches zero with the vehicle still moving. The brake is applied during brakingwhen rotational speed increases to a predetermined time- varying value after brakerelease. During acceleration, the brake is applied when rotational speed increases so thatspeed variation is greater than the aforementioned maximum permissible value, and isreleased when rotational speed falls to a predetermined time-varying value after thebrake application. The brake remains unaffected when speed variation is less than themaximum permissible value. The brake is also applied on braking (or released onacceleration) once a predetermined period elapses after the brake is released (applied),which period is a percentage time increment added to the period between a previousrelease and application (applicationa and release) of the brake.
