Anti-skid controller

Abstract

Abstract PURPOSE: To surely preset a braking target even for the increase of coefficient of friction during braking operation, by presetting a new linear braking target when speed of a wheel reaches a straight line below the linear braking target. CONSTITUTION: A speed signal Vw from an f/V converter 3 is differentiated by a decelerated speed detector 4 and converted into a wheel decelerated speed signal αw. The decelerated signal αw is compared with a prescribed value αb in a comparator 6 and differntiated by a differentiating circuit 6, and a signal e b is output when exceeding the prescribed value. A linear target generator circuit 7, on the basis of said signal e b , outputs a linear target v o , and a converter 8 multiplies constant K to the above target, while a comparator 9 compares said value with the wheel speed Vw to reset RS-SS11 through a differentiator 10. A skid control unit 15 outputs a control signal for brake oil pressure by those from an AND gate 12, operated by outputs of RS-FF11 and the comparator 9, and a signal e a output from a comparator 13 and differentiator 14 which compare the wheel decelerated speed αw with a prescribed value -αa.
