Abstract
Various arithmetic processings for skid control are performed by using the memory in which the data representing the relationship between the brake releasing period and the slip rate to be controlled and by using a microcomputer having at least one free-running counter. In the arithmetic processing of the wheel speed, the contents of the free-running counter are successively stored in the memory in response to interrupt processing signals synchronized with the wheel speed pulses and the wheel speed is calculated from the difference between the contents of the counters written in the memory. Similarly, the measurement of the brake releasing period is also performed by calculating the difference between the written count values. The suitable slip rate is taken out of the memory on the basis of the measured brake releasing period.
