Localization with synchronized emissions for coupled wheels

摘要

A disclosed system for monitoring and locating a position of a tire pressure monitoring device within a tire includes a controller configured to detect a first transmission from a first sensor installed within a first wheel and a second transmission from a second sensor installed within a second wheel coupled to the first wheel. The controller and system utilizes a relative angular position corresponding to receipt of the transmissions to identify a lead and trailing tire pressure monitoring device. The controller is then enabled to correlate the signals with a known sequence of sensors to determine within which of the coupled tire assembly includes which tire pressure monitoring device.

1. A method of configuring a controller to detect a location of a tire pressure monitoring sensor comprising:
configuring a controller to detect a first transmission from a first sensor installed within a first wheel; configuring the controller to detect a second transmission from a second sensor installed within a second wheel coupled to the first wheel; configuring the controller to recognize that the first wheel and the second wheel are comprised in a wheel assembly, the recognizing comprising detecting that the first wheel and the second wheel rotate at a common speed; configuring the controller to correlate a first angular wheel assembly position with one of the first and second transmissions and a second angular wheel assembly position with the other of the first and second transmissions, wherein the correlating comprises correlating a tire pressure monitoring sensor identification tag with a respective one of first and second angular wheel positions at a time of receipt of a respective one of the first and second transmissions; and configuring the controller to determine the location of each of the first and second sensors relative to the wheel assembly based on a comparison between the first angular wheel assembly position, the second angular wheel assembly position, and a predetermined relative angular relationship between the first sensor and the second sensor, wherein the determining of the location of each of the first and second sensors relative to the wheel assembly comprises determining which of the first and second sensors is a lead sensor and upon determining the lead sensor determining the location of at least one sensor other than the lead sensor relative to a vehicle and the wheel assembly based at least in part on the sequence of receipt of a transmission from at least one sensor other than the lead sensor with respect to receipt of a transmissions from the lead sensor, a relative angular position of the at least one sensor other than the lead sensor with respect to the lead sensor, and direction of rotation of the wheel assembly.
