Trailer vehicle and trailer control system
Trailer vehicle and trailer control system
A method of controlling brake pressures in a trailer vehicle braking system, which comprises a trailer brake module (TBM) for controlling a braking force on a wheel or wheels on the trailer (1-4, fig. 1). 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. The second EDU may be provided with a power supply independent of the TBM power supply and a communication channel to the towing vehicle independent of the TBM communication channels to the towing vehicle. The present system may ensure braking performance is maintained in the event of a power supply failure.
