Antiskid controller

Abstract

Abstract PURPOSE: To perform an optimum antiskid control according to the road condition by detecting the wheel deceleration, and setting a desired value for skid control of the wheels based on the wheel speed in each skid cycle at which the detected deceleration agrees with a value set previously. CONSTITUTION: When the brake is applied at a time t 0 , a skid controller 60 is actuated, and a wheel speed VW detected by means of a wheel speed sensor 70 shows a skid cycle in Fig. A. The wheel speed VW is differentiated in a set deceleration detector 80, which detects the deceleration shown if Fig. B and outputs signals e b at times t 1 , t 2 , t 3 ... at which the deceleration reaches values set previously. Then a desired wheel-speed generator 90 extracts wheel speeds V w1 , V w2 ... at times when the signals e b are obtained, and generates a desired wheel-speed V w0 made by linking the wheel speeds V w1 , V w2 ... into a straight line shown in Fig. C. The desired wheel-speed thus generated is inputted to a skid controller 100 for rear wheels, and a skid control of the rear wheels is performed so that the wheel speed agrees with the desired value.
