First Claim
1. A controller for a tire pressure monitoring system comprising:
- a plurality of wheel speed ports for receiving wheel speed sensor signals, each of the plurality of wheel speed ports correlated with a specific wheel location;
a communication port for receiving a plurality of tire characteristic messages, the tire characteristic messages including at least one of a unique sensor identification and tire characteristic information; and
a processing unit comprising control logic, wherein the processing unit is in communication with the plurality of wheel speed ports and the communication port and the control logic is capable of;
receiving a signal indicative of a wheel speed at a first wheel speed port correlated with a first wheel location;
receiving a tire characteristic message at the communication port within a predetermined time period of receiving the signal indicative of the wheel speed correlated with a first wheel location;
determining the wheel location of the tire characteristic message as being the first wheel location based on the association of the wheel speed signal and the tire characteristic message; and
assigning the unique sensor identification to the first wheel location.

Abstract
Various embodiments of an apparatus and method for configuring a tire pressure monitoring system are disclosed. One method comprises rotating a first tire of a plurality of tires on a vehicle and receiving a signal indicative of the speed of rotation of the first tire from a wheel speed sensor associated with the first tire. A controller associates the first tire with a wheel location in response to receiving the signal from the wheel speed sensor. A tire pressure sensor in the first tire generates a tire characteristic signal in response to the rotation of the first tire. The controller receives the tire characteristic signal and associates the tire characteristic signal with the wheel location in response to receiving the tire characteristic signal within a predetermined time period from receiving the signal indicative of the speed of rotation of the first wheel.
