Abstract
A vehicle friction brake control system applicable in both brake and power modes for controlling slip and slide of the vehicle wheels utilizes a speed signal for each vehicle axle whose amplitude is dependent upon axle angular speed. There is a front axle speed comparison circuit and a rear axle speed comparison circuit. Each of the speed comparison circuits utilize speed signals from their respective axles, as well as electrically isolated speed signals from the other axles. The speed comparison circuits each compare the highest or lowest axle speed from their respective axles with the highest or lowest of all four axle speeds to provide a slip/brake system signal.
