Abstract

PURPOSE:To eliminate the erroneous function due to the noise by holding the speed low peak level for predetermined time to use as the reference of the comparision. CONSTITUTION:The wheel speed signal Vw is provided to a simulation speed generating circuit 3 and a low peak level holding circuit 8. The outputs from said circuits are compared with the wheel speed signal Vw at the comparators 4, 9 to produce the set/reset signal of F/F circuit 5 thus to produce the operating signal of a solenoid 7. Said solenoid operating signal is also led to a timer 11 to control the holding operating of the low peak holding circuit 8 through OR circuit 10. Consequently the low peak is held for predetermined time from the stopping of the braking force dropping signal and during this interval the wheel speed is compared with the low peak. Since the low peak is employed as the speed reference at the rising of the wheel speed, the erroneous function due to the noise can be eliminated.
