Abstract
A vehicle control system of a vehicle includes a trailer brake control electronic control unit (ECU), which in turn includes a trailer brake output circuit. The trailer brake control ECU is configured to receive an electronic parking brake (EPB) state flag and a vehicle acceleration message. The dynamic EPB state flag indicates one of an ON state and an OFF state of a dynamic EPB, and the vehicle acceleration message indicates an acceleration of the vehicle. The trailer brake control ECU outputs, via the trailer brake output circuit, a trailer brake signal based on the acceleration of the vehicle indicated by the received vehicle acceleration message in response to determining that the received dynamic EPB state flag indicates the ON state.
