Abstract
The vehicle brake system includes electronic control logic and an electrically controllable pressure modulator for the brake actuating device of each wheel responsive to the output of the control logic. A brake-signal transmitter transmits to the control logic the value of the desired vehicle deceleration and a deceleration responsive device mounted on the vehicle transmits to the control logic the value of the actual vehicle deceleration. The control logic adjusts the brake pressure supplied by each pressure modulator by a signal dependent upon the difference between the desired value and actual value of the vehicle deceleration. The brake system disclosed is an all digital system and is not temperature sensitive. The brake system also includes antiskid capabilities.
Claims36
A vehicle brake system comprising:
- an electronic control unit to provide a control signal;
- a plurality of electrically controllable pressure modulators each coupled to said control unit and to a different brake actuating device responsive to said control signal for controlling said brake actuating device associated therewith;
- a brake pedal actuated brake-signal transmitter coupled to said control unit providing a first signal to said control unit representative of a desired value of vehicle deceleration;
- and
- a decelerometer fastened to said vehicle and coupled to said control unit providing a second signal to said control unit representative of the actual value of vehicle deceleration, said control unit providing said control signal dependent on the difference between said first and second signals.
