ANTISKID BRAKE SYSTEM FOR VEHICLES

摘要

A vehicle antiskid brake system in which the brake pressure is reduced at one or more wheel deceleration thresholds and the brake pressure is increased when the maximum wheel acceleration is reached. Thus the brakes are reapplied before the wheel has reached the vehicle speed and at a time when the brake force coefficient is greatest. An electronic circuit closes an inlet valve and opens an outlet valve in the brake line to the wheel when the deceleration threshold is reached. Although the outlet valve is closed when the wheel deceleration is reduced to a point above the threshold, a timing circuit keeps the inlet valve closed until a differentiating circuit generates a signal indicating that the acceleration of the wheel has reached a maximum value, whereupon the inlet valve is opened to complete the cycle.
