ELECTRONIC CONTROL FOR TRAILER BRAKES

摘要

A control circuit (12) for trailer brakes (14) is provided which includes a force sensor (54) on the trailer hitch (38) to monitor and control braking force, and which results in improved control of the towing vehicle (42) and reduced wear on the trailer brakes (14). Closed loop feedback control logic in the control circuit monitors the force exerted by the trailer (40) on the hitch. The feedback control logic governs the application of the trailer brakes (14) to maintain a braking force such that a consistent, predictable force is exerted by the trailer on the towing vehicle through the hitch during braking.
