Abstract

PURPOSE:To eliminate an effect of temperature and improve the difference in wheel revolution detection accuracy in a low revolution by changing the respective right and left wheel speed pulses into the respective up and down counting pulses and detecting the difference in wheel revolution from that in both counts. CONSTITUTION:The signals generated in wheel speed sensors 10 and 20 are converted into square waves by waveform shaping circuits 30 and 40 and input to a change-over switch 60. The said switch 60 is switched by the output of the aquare wave generation circuit 50. For example, when an up and down counter 70 is set in up count mode, it inputs the signals of the sensor 10 and when in down count mode, it inputs those of the sensor 20. After down counting is completed, the output of the counter 70 is compared with that of setting circuits 100 and 110 by compare circuits 80 and 90. As a result, actuators 140 and 150 are driven through amplifiers 120 and 130. The compare timing is controlled by a logical circuit 160.
