Abstract
A method and device for locating n wheels of a vehicle each equipped with an electronic module designed to emit, to a central unit, electromagnetic signals representative of operating parameters of each wheel and an identification code of the latter. There is, in a fixed position on the vehicle, in the vicinity of at least (n-1) wheels, a radio-tag in which is stored a location code, able to be identified by the central unit and enable the latter to locate the position of the radio-tag on the vehicle. In order to locate the wheels, an activation of each radio-tag is controlled so as to deliver to the central unit a signal incorporating the location code of this radio-tag associated with the identification code of the wheel located in the vicinity of the latter. The electromagnetic signals incorporate a final portion consisting of a pure wave, and the activation of the radio-tags is done so as to insert the location codes into the electromagnetic signals by modulating the absorption/reflection of the pure waves.
