Abstract
An electronic braking system (EBS) for a towing vehicle which provides for trailer service brake pressure supply via an additional EBS sub-system, and wherein, in order to speed up the application of trailer braking, the electrical signal representing the driver's braking demand is processed to generate an additional pressure pre-pulse of predetermined amplitude to pressurise the trailer braking circuit in advance of the proportional pressure setting determined by the driver. The pre-pulse is made up of two parts, a preset fixed duration pulse followed without break by a variable duration continuation pulse. The variable duration of the variable duration pulse is determined primarily by the rate of increase of the driver's demand signal.
