System for monitoring the pressure of tires of a motor vehicle

摘要

According to one exemplary embodiment, a system for monitoring the pressure of tires of a motor vehicle with location of the wheels comprises a monitoring element and a pressure sensor. Each pressure sensor is associated with a transmitter with which it transmits to the monitoring element a radio signal comprising sensor identification data. The system comprises a means for determining the phase shift between two radio signals transmitted at two distinct times for each wheel. The system further comprises a means for determining the rotation angle, modulo 2pi, traveled by each of the wheels between the two times. The system further comprises a means for comparison between the phase shifts and the rotation angles.
