System for measuring parameters associated with motor vehicle wheels

A motor vehicle comprising:

• a plurality of wheels;
• a power system configured to power the motor vehicle;
• and
• a system for measuring parameters associated with the plurality of wheels of the motor vehicle, the system comprising:
• a plurality of electronic measuring devices each mounted in a wheel of the plurality of wheels of the vehicle in order to measure parameters associated with said wheel and an electronic control unit of said plurality of electronic measuring devices, each electronic measuring device of the plurality of electronic measuring devices being configured to determine a set of proximity scores with respect to each of the other electronic measuring devices of the plurality of electronic measuring devices and to send said set of proximity scores that have been determined to the electronic control unit, said electronic control unit being configured to receive from each respective electronic measuring device of the plurality of electronic measuring devices the set of proximity scores and to determine the location of each respective electronic measuring device of the plurality of electronic measuring devices from said respective received set of proximity scores,
• wherein each electronic measuring device of the electronic measuring devices is configured to function in an initialization mode that is a sender mode in which the sending electronic measuring device sends an initialization message coded in radio-frequency signals sent at increasing power levels to other receiving electronic measuring devices of the electronic measuring devices, said initialization message including an identifier of the sending electronic measuring device, each receiving electronic measuring device of the receiving electronic measuring devices being configured to receive at least one said initialization message sent by the sending electronic measuring device and to send at least one response message including at least the identifier of said receiving electronic measuring device, the sending electronic measuring device being configured to receive a response message from each of the receiving electronic measuring devices in order to determine the set of proximity scores with respect to the receiving electronic measuring devices.
