ABSTRACT:
An anti-skid control system, according to the present invention, samples the input timing of the first pulse of each group of a given number of sensor signal pulses, which given number is so adjusted that the difference between the durations of successive pulse groups is great enough to accurately perform the anti-skid control operation based thereupon. Each of the sampling input timing values is provided a label identifying the required processing operations for performing the anti-skid control. The anti-skid control system performs the sampling operation as an interrupt routine intermittently interrupting a main job which derives a control signal for increasing, decreasing or holding constant the fluid pressure applied to the wheel cylinder. The main job contains a plurality of different routines for processing the sampled input data, one of which is to be identified and performed in accordance with the identification in the label. A count of the occurrences of interruption is incremented whenever an interrupt occurs and is decremented upon completion of each cycle of the main job. The sampling routine is performed in response to the first of each group of the given number of sensor signal pulses. When the difference between the durations of successive pulse groups is less than a predetermined value, then the number of sensor signals to be ignored before sampling the input timing of the first pulse of the next group is increased until the difference becomes greater than the predetermined value.
