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 out a speed signal corresponding to the wheel speed, and sends out a high μ road signal when the vehicle has high acceleration/deceleration, and a low μ road signal when the vehicle has low acceleration/deceleration. It has a G sensor that detects whether the brake is on or off, a brake switch that detects whether the brake is on or off, and a modulator that controls the brake fluid pressure of the brake piping. When a high μ road signal is received, a high μ road signal is received.
When the low μ road signal is received during brake fluid pressure control for high μ roads by the road anti skid control means, anti skids are prevented by controlling the brake fluid pressure for low μ roads by the low μ road anti skid control means. In an anti-skid control device having a control means, a calculation means for calculating a fluctuation frequency of the speed signal when the brake is off, and an output from the calculation means and a predetermined value are compared, and if the output is equal to or greater than the predetermined value. The system includes a comparison means for sending out a bad road signal when the road is considered to be bad, a high μ road signal generating means for generating and sending out a high μ road signal, and a brake on signal received after receiving the bad road signal. in case of,
The high μ signal is used instead of the road surface μ signal from the G sensor.
1. An anti-skid control device comprising a controller comprising switching means for sending a high μ road signal from a road signal generating means to the anti-skid control means.
