ABSTRACT:
A trailer braking control system which is adapted to modify trailer braking from a towing vehicle by regulating the coupling head service braking pressure signal generated on the towing vehicle in response to driver's demand pressure and measured values of longitudinal force exerted on the trailer coupling just before and during braking. At least two adaptive variables are developed on the towing vehicle, and on selected qualifying stops of the towing vehicle/trailer combination, one of these adaptive variables is chosen to be corrected at the end of that stop using average trailer thrust error signals for use in regulating trailer braking on subsequent stops.
