Method for detecting a change in location of the wheels of a motor vehicle

A method for detecting a change in location of the wheels of a motor vehicle, said vehicle having at least:

• one processor,
• two wheel units which each comprise an electronic assembly of sensors and which are each mounted on one of said wheels of the motor vehicle, and
• one bidirectional radiofrequency communications assembly designed to ensure communication between the wheel units and the processor,
• wherein the method includes at least:
• a monitoring step, during which each wheel unit emits series of messages to the processor via the communications assembly depending on a determined emission rate, when the motor vehicle is at a standstill, and the processor establishes and records, for each wheel unit, a first pattern representative of the location of the wheel unit in the motor vehicle, by measuring a power of said received messages, wherein the power of the received messages is a Received Signal Strength Indication (RSSI) of the received messages, an evaluation step, during which the processor measures a possible first variation in each first pattern and the processor compares said first variation with a first predetermined threshold value, the location of the wheel in question is estimated to have changed if said first measured variation is greater than the first predetermined threshold value, and
• a locating step, which aims to determine the location of the wheels on the motor vehicle and which is implemented if the location of at least two wheels is estimated to have changed during the preceding evaluation step.
