<p>PURPOSE:To enable braking control behaviour and wheel speed upon an accident or the like to be reproduced, by actuating a wheel speed memory in response to a brake actuating signal or a skid-control signal. CONSTITUTION:A skid evaluating circuit 2 issues control signals 12, 13 for controlling solenoid valves 10, 11. The control signals 12, 13 together with a brake operating signal 21 are delivered to an OR circuit 27 which issues output signals into a shift register 16 and an AND circuit 27. Due to the output signals received by the shift register 16 and the AND circuit 27, clock pulses 29 are delivered to a counter 30, and a wheel speed signal is stored in a memory 17 through an A-D converter 14 and a latch circuit 15. Thereby, the behaviour of braking operation may be stored, and the wheel speed may be stored and reproduced by the control signals 12, 13 in accordance with the quick reduction of wheel speed upon an accident or the like.</p> |
