Abstract

Trailer Brake System A method of controlling brake pressures in a trailer vehicle braking system, which comprises a trailer brake module for controlling a braking force on a wheel or wheels on the trailer. The trailer brake module receives data inputs from sensors on the trailer and a control pressure from a towing vehicle in a control line. The braking system comprises a second ECU configured to receive sensor inputs from sensors on the trailer to communicate with the trailer brake module and with the towing vehicle. If the second ECU determines that the control pressure should be increased or decreased, the second ECU sends a request to the towing vehicle to increase or decrease the control pressure, respectively.
