Embodiment Construction

[0010] Although aspects of the invention have been described with reference to the specific embodiments, the invention is not limited to these embodiments, and additional modifications, applications, and implementations can be made without departing from the invention. In the drawings, the same reference numerals will be used to denote the same components. Those skilled in the art will recognize that the various components set forth herein can be altered without altering the scope of the invention. The present invention is described in connection with a trailer and towing vehicle equipped with integrated trailer brake control as described in U.S. Patent 6,966,613 and a tire pressure monitoring system as described in U.S. Patent 7,026,922, the entire contents of which are incorporated by reference here. It should be noted, however, that the present invention may also be implemented with a non-integrated trailer brake control, such as with an aftermarket trailer brake controlle...

Abstract

A system and method that, upon connection of a trailer to a tow vehicle, a trailer brake controller informs a tire pressure monitoring system to begin monitoring information at the TPMS and at the same time, activates the initiators, i.e., the electromagnets. Sensors respond to the electromagnetic field that is generated by electric brake magnets. As a result, the sensors transmit RF signals that are received by the tire pressure monitoring system. Transmissions from the sensors are decoded in a controller and processed as necessary for tire pressure monitoring automatically calibrated to the tire pressure monitoring system and the system can request the pressure data from the sensors by way of the low frequency field generated by the electric brakes.

Description

technical field [0001] The invention relates to the monitoring of tire air pressure, in particular to the monitoring of trailer tire air pressure. Background technique [0002] Various pressure sensing systems have been proposed for monitoring the air pressure in tires of motor vehicles. 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. There is a need to monitor the tire condition of the trailer tires and the primary vehicle tire condition. A disadvantage of the known method is that the intervention of the driver is required in order to set the system correctly. The driver must calibrate the RF receiver with the associated se...
