<p>A fail-safe system for an automotive anti-skid control system ensures that manual control of vehicle brakes is enabled if any system components should fail. The anti-skid control system employs actuators to control the brakes automatically, the actuators being powered by a vehicle battery. The power supply to the actuators is interrupted by the fail-safe system if malfunction of any system components is detected. Specifically, the fail-safe system checks for open or short circuits in the actuators themselves, inaccuracy or failure of any of a plurality of wheel speed sensors, excessive or insufficient battery voltage, and malfunction of major system components such as a hydraulic pump used to expedite automatic control, signal processing units, etc. The particular type of malfunction may be recorded for reference during maintenance and repair.</p> |
