Abstract
A vehicle braking system of the type having an electronic control computer for determining the extent of application of the vehicle brakes in accordance with given driver braking demands, includes a plurality of analogue transducers which provide analogue input signals to the electronic control computer representative of a corresponding plurality of variable operating parameters, such as driver braking demand, axle load, applied braking pressure, and vehicle decelerations. In order to enable recalibration of said transducers new zero/tare figures from each transducer are entered into the control computer and provided they pass a process of checking, are arranged to override the existing zero/tare data, whereupon they are used by the system until the next zero/tare recalibration service operation is selected.
