Abstract
An anti-skid system in which a low-pressure sensor generates a signal when the primary brake fluid pressure falls below a minimum level. In that case, the low-pressure signal is applied to the anti-skid brake action controller to diminish the frequency of actuation of the brakes so as to conserve brake fluid. In a variant of the invention, the low-pressure signal is used to temporarily cancel the action of the anti-skid system to conserve brake fluid.
Claims9
An anti-skid braking system for a wheeled vehicle, including a brake fluid pump and a brake fluid pressure reservoir, sensors for generating wheel signals related to wheel motion, and a brake pressure controller for receiving said wheel signals and for controlling anti-skid braking pressure applied to said wheels during a skid;
- wherein the improvement comprises a brake fluid pressure sensor for sensing the pressure of said brake fluid in said pressure reservoir and for controlling an electrical signal due to low brake fluid pressure in said reservoir which is applied to said brake pressure controller;
- circuit means for effecting at least partial cancelling of said anti-skid braking action when said pressure sensor delivers an electrical signal after a predetermined period of time;
- said circuit means including a timing member which generates an electrical signal after a predetermined time to block actuation of a portion of said anti-skid braking pressure whereby, when said fluid pressure in said reservoir decreases, the anti-skid action by said pressure controller is at least partially cancelled.
