のフエールセーフ装置。 In a vehicle anti-lock system, when a sudden drop in wheel acceleration is detected based on the wheel speed, an anti-lock control signal is output to a hydraulic pressure regulating device that cuts off the transmission of brake fluid to the brake device or reduces the pressure. A normally closed switch means for turning on and off the transmission of an anti-lock control signal to the adjustment device, a parking brake operation detection means for detecting the operation of the parking brake, and a parking brake operation detection signal from the parking brake operation detection means and the wheels. 1. A fail-safe device for a vehicle anti-lock system, comprising switch control means for turning off the switch means when a speed signal is input.
