悪路制御手段とからなるコントローラを具備して
いることを特徴とするアンチスキツド制御装置。 a wheel speed sensor that detects the speed of each wheel of the vehicle and sends a speed signal corresponding to the wheel speed; a brake switch that detects whether the brake is on or off;
A modulator that controls the brake fluid pressure of each brake pipe, each drive circuit that sends out a drive signal to operate each modulator, and one that detects whether or not the wheels tend to lock based on the speed signal. If a wheel has a tendency to lock, the drive circuit that drives the modulator on the side of the wheel that has a tendency to lock releases the brake fluid pressure, and then steps the brake fluid pressure with a hold time in between. In the anti-skid control device, the anti-skid control device includes an anti-skid control means for transmitting an anti-skid signal that increases the speed of the vehicle, and a calculation means for calculating a fluctuation frequency of the speed signal when the brake is off, and an output from the calculation means is compared with a predetermined value. However, if the output is greater than the predetermined value,
Comparison means that sends out a bad road signal indicating that the road is bad; and if a brake-on signal is received after receiving the bad road signal and an anti-skid signal indicating that the rear wheels are in a tendency to lock is received; An anti-skid control device comprising a controller comprising rough road control means for holding an anti-skid signal without sending it to the drive circuit.
