キッド制御装置。A skid control system for a vehicle having at least one wheel and a brake for the wheel, comprising a wheel deceleration detection device for sending a current representative of deceleration of the at least one wheel and responsive to an output signal to increase the magnitude of the reference current. and a reference current generating device that generates a reference current of a constant magnitude, including a device that reduces the magnitude of the reference current with a constant delay after the output signal, and a current representing the wheel deceleration and the reference current. When the relationship between them reaches a constant relationship, the output signal is sent, and when the relationship between the current representing the wheel deceleration and the reference current having the increased magnitude reaches a constant relationship, the brake is activated. send a release signal,
Further, the current representing the wheel deceleration and the reference current having the reduced magnitude are compared, and the brake re-activation is performed because the relationship between the current representing the wheel deceleration and the reference current having the reduced magnitude is constant. A skid control device comprising: a comparator circuit device for transmitting a signal; and a brake modulator device for releasing the brake in response to the brake release signal and reapplying the brake in response to the brake reapply signal.
