Abstract
A system and method that, upon connection of a trailer to a tow vehicle, recognizes the trailer and applies a stored trailer configuration in a controller. In one embodiment, tire pressure sensors transmit RF signals that are received by the tire pressure monitoring system. Transmissions from the sensors are decoded in a controller and processed to identify, or create a particular trailer configuration as well as implement tire pressure monitoring automatically calibrated to the particular trailer configuration based on the sensor identifications for the tire pressure sensors. In another embodiment, the trailer configuration includes a pulse width modulated gain control for the trailer brakes.
