Wheel anti-skid brake control system for a road vehicle
First Claim
1. A wheel anti-skid brake control system for a road vehicle having at least two axles with wheels at opposite sides thereof, each wheel being provided with a fluid pressure operative brake cylinder device to which a source of fluid pressure is connected via an operator'"'"'s control valve device, said system comprising:
- (a) sensor means for providing output signals in accordance with different dynamic wheel behavior conditions of one wheel of each of said at least two axles of said vehicle, said one wheel of one axle being diagonally opposed to said one wheel of the other axle;
(b) modulating valve means associated with each said brake cylinder device for influencing the fluid pressure connected thereto via said operator'"'"'s control valve device;
(c) evaluation means for each axle subject to said output signals representing the behavior conditions of said one wheel of a respective one of said axles for effecting operation of each said modulating valve means associated with said respective one of said axles; and
(d) means for connecting the fluid pressure at one of said brake cylinder devices of a respective one of said axles with the other brake cylinder device thereof.

Abstract
A wheel anti-skid brake control system for an automotive type vehicle in which diagonally opposed wheels on different axles of the vehicle are provided with a sensor device whose output signals represent different dynamic wheel behavior conditions. An electro-pneumatic modulator valve is operative in a common line via which fluid pressure is delivered to each brake cylinder device of an axle or in a separate line connected directly to each individual brake cylinder device of the axle to influence the brake pressure delivered to each brake cylinder via an operator'"'"'s control valve device in accordance with the output signals of the sensor device of one wheel of the axle, as monitored by an evaluation circuit to which the modulator valve or valves of the axle are operatively connected.
