Abstract
A method for automatically locating a motor vehicle wheel comprises the following steps: transmission by the wheel unit (to) of high-frequency signals representing, at least, the wheel pressure whereon the wheel unit is mounted, and a code identifying the wheel; reception by the central unit () of the high-frequency signals transmitted by the wheel unit. The method further comprises the following steps: transmission of low-frequency signals by at least a transmission device (') mounted on the vehicle proximate to the wheels along a predetermined position, so as to activate the units arranged proximate; reception of the low-frequency signals by the wheel units and in response, transmission of high-frequency signals by the activated wheels, the signal comprising at least the code identifying the activated wheels, and reception of the high-frequency signal by the central unit () associated with the code identifying the activated wheels, at the position of the transmission device(s)′).
