Abstract
A system for identifying the position of a tire on a vehicle based on wireless messages received from the tire includes a receiver circuit, a signal strength circuit, a memory, and a processing circuit. The receiver circuit is configured to receive the wireless messages. The signal strength circuit is configured to determine the signal strengths of the wireless messages. The memory is configured to store a predetermined frequency distribution. The processing circuit is configured to provide a frequency distribution of the wireless messages based on the signal strengths and to compare the frequency distribution to the predetermined frequency distribution to determine the position of the tire on the vehicle.
