Abstract
The invention relates to a by-wire brake system. There is a need for a trailer brake control circuit for a by-wire brake system. A brake control circuit for trailer brakes in a by-wire brake system includes a hydraulic pump or a supply of pressurized air, a hydraulic reservoir or an air vent, a pair of solenoid operated proportional valves for controlling communication between the pump, the reservoir and the trailer brakes, and a pair of solenoid operated shutoff valves, each controlling communication between the trailer brakes and a corresponding one of the proportional valves.
