Abstract
A driver braking demand indicator apparatus comprises a brake valve including (i) a brake valve member movable in response to a driver moving a brake applicator member, and (ii) a delivery pressure line to operate a vehicle service brake circuit. The apparatus also comprises a travel sensor arranged to (i) sense movement of the brake valve member, and (ii) provide a first signal indicative of the extent of travel of the brake valve member when movement of the brake valve member is sensed. The apparatus further comprises a delivery pressure line sensor arranged to (i) sense pressure in the delivery pressure line of the brake valve, and (ii) provide a second signal indicative of the pressure in the delivery pressure line. The apparatus also comprises a controller arranged to process the first and second signals to provide a driver braking demand signal for at least one external device.
