Antilock braking system with device for delaying yaw - evaluates difference between braking pressures at wheels on one axle and imposes pulsatile braking where needed

摘要

The brake valve (1) operated from the brake pedal (2) supplies fluid pressure from a source (3) to left- and right-hand side braking pressure control valves (4a,4b) for respective wheels (5a,5b). Signals from wheel speed sensors and comparators (8a,8b) of actual and desired pressures (9a,9b) are forwarded to a processor (6). A yaw build-up delay device therein prevents excessive braking where the adhesion is poorer, and also provides for synchronised pulsation of the braking pressure at both wheels. ADVANTAGE - Controllability and ride comfort of vehicle enhanced even in conditions of unequal adhesion coeffts. at different wheels.
