Abstract
An electronic braking system for a multi-axle road vehicle, having a foot-operable braking transducer which generates electrical braking demand signals representative of a driver's braking demand, load transducers which generate electrical load signals representative of the respective load on different axles of the vehicle, and in electronic controller which receives the braking demand signals and load signals and generates electrical output signals for controlling the operation of braking devices for the wheels carried by axles, the controller including adaptive load compensation device which acts to modify the output signals of the controller to the various braking devices so as to take account of prevailing loads on the respective axles. The system can be brought into a test mode wherein in place of the electrical braking demand signals representative of a drivers braking demand, a preset standard braking input demand is applied to the controller whereby the system generates for testing purposes compensated braking pressures which take into account the operating values of the axle loads.
