Abstract

Aspects of tire sensor auto-location are described. A sensor position detection device receives tire sensor values from a tire sensor device. The tire sensor values are measured or calculated for tire footprint length, longitudinal acceleration, and lateral acceleration. The sensor position detection device generates a longitudinal acceleration coefficient and a lateral acceleration coefficient using these values, and assigns the tire sensor device to a particular tire position of a vehicle based on a sign of the longitudinal acceleration coefficient and a sign of the lateral acceleration coefficient.
