Anti-skid controller

Abstract

Abstract PURPOSE:To shorten braking distance by providing a control interruption means which interrupts the anti-skid control when it is determined that road state is rough according to a detecting signal of a road face sensor at the braking time. CONSTITUTION:When braking is applied at the running time on a rough road such as gravel road or the like, the output of a road sensor 8 using piezo element is increased because a resonant component arranged below a spring becomes great, so that the output voltage of a signal processing circuit 9 is increased over a reference voltage Vref. Since the output of a comparator 10 reaches an H-level, the rough road is identified so that independent anti-skid control for front wheels may be released. That is, braking liquid pressure from a master cylinder 5 is directly supplied into right and left front wheel cylinders 7a and 7b so that the braking state is returned into the normal braking state. The braking lock for the front wheels can be performed, hence shortening braking distance.
