Skid control method

摘要

A skid control device employs a wheel speed sensor and the control circuit which includes a microcomputer. The microcomputer computes wheel speed on the basis of a pulse signal derived from the wheel speed sensor and delivers a break releasing signal when the wheels slip. A brake control apparatus for controlling the pressure of oil for applying the brakes to the wheels responds to the outputs of the microcomputer. The microcomputer contains a free-running counter which counts clock pulses and a memory containing a sequence of storage locations. This sequence of storage locations stores count values of the free-running counter. A pulse signal from the wheel speed sensor is employed to produce an interrupt request for the microcomputer. The contents of successively adjacent locations in memory are employed by the microcomputer for carrying out the necessary calculations and computing wheel speed.
