Abstract
An electronically controlled fluid pressure braking system for a heavy duty vehicle includes an operator controlled mechanism which generates independent brake pressure command signals, each of which are transmitted to separate auxiliary controllers. Each of the controllers transmits its command signal to the other auxiliary controllers and also to a master control unit. The master control unit sorts between the command signals and generates a preliminary brake pressure request signal which is transmitted back to each of the auxiliary controllers. Each of the auxiliary controllers then examines the brake pressure request signal received from the master controller and actuates the corresponding vehicle brakes if the pressure request signal is within normal limits. If the signal is not within normal limits, each of the auxiliary controllers is capable of generating a brake pressure request signal independently of the master control unit.
