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 2,
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.
