Abstract
A controller includes a foot brake valve electrical input port, which is capable of receiving an electrical signal indicative of a foot brake delivery pressure, and a trailer brake valve electrical input port, which is capable of receiving an electrical signal indicative of a trailer brake delivery pressure. The controller also includes control logic that is capable of receiving the electrical signal indicative of the foot brake delivery pressure, receiving the electrical signal indicative of the trailer brake delivery pressure, based on an electrical level of the electrical signal indicative of the foot brake delivery pressure, determining if the foot brake delivery pressure is above a predetermined threshold pressure, and based on a presence of the electrical signal indicative of the trailer brake delivery pressure, determining if the trailer brake delivery pressure is above the predetermined threshold pressure. The controller also includes control logic that is capable of transmitting a signal from an electrical stop light control port for controlling a vehicle stop light based on the electrical signal indicative of the foot brake delivery pressure and the electrical signal indicative of the trailer brake delivery pressure.
