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.

Description

technical field [0001] The present invention relates to a method of identifying a trailer being towed by a vehicle, and more particularly to a method of identifying a trailer which utilizes a tire pressure monitoring system and applies or stores trailer configurations to track trailer usage. Background technique [0002] Various pressure sensing systems have been proposed for monitoring the air pressure in the tires of a motor vehicle or trailer. These systems use electromagnetic signals to generate a pressure signal and transmit that signal to a receiver. This pressure signal corresponds to the air pressure inside the tire. When the pressure drops below a preset pressure, the operator of the vehicle is notified of the low pressure with an indicator. [0003] Sports utility vehicles and other large vehicles are often used to tow trailers, and it's also not uncommon for a single owner to have more than one trailer. Even if there is only one trailer, it would be desirable t...
