Embodiment Construction

[0036] exist figure 1 The locating device according to the invention shown as an example in , is used for locating the wheel position of a vehicle.

[0037] More specifically, the locating device is intended to be mounted to a vehicle provided with a tire pressure monitoring system such as figure 1 vehicle shown), the tire pressure monitoring system is intended to equip a vehicle V having four wheels, usually fitted with tires: two front wheels 1, 2 and two rear wheels 3, 4.

[0038] Such a monitoring system usually comprises, first of all, an electronic module 5-8 associated with each wheel 1-4, for example fixed on the rim of said wheel so as to be positioned inside the tire casing.

[0039] Each of these electronic modules 5-8 contains, for example, sensors dedicated to measuring parameters such as tire pressure and / or temperature, a microprocessor computing unit with an identification code for said electronic module, and a radio frequency connected to a high-frequency an...

Abstract

The invention relates to a method and a device for locating the n wheels (1-4) of a vehicle (V) each provided with an electronic housing (5-8) capable of transmitting, to a central unit (9) electromagnetic signals representative of functional parameters of each wheel and an identification code of the latter. The method of the invention comprises providing, in a fixed position on the vehicle (V) in the vicinity of at least (n-1) wheel (1-4), a radio label (10-13) having stored therein a location code that can be identified by the central unit (9) and enables the latter to locate the position of said radio label on the vehicle (V). The method further comprises, in order to locate the wheels, controlling an activation of each radio label (10-13) in order to supply to the central unit (9) a signal including the location code of said radio label (10-13) associated with the identification code of the wheel (1-4) in the vicinity of the latter. The electromagnetic signals further include an end portion including a pure wave, and the activation of the radio label (10-13) is carried out so as to insert the location codes into the electromagnetic signals by modulating the absorption / reflection of said pure waves.

Description

technical field [0001] The present invention relates to methods and apparatus for aligning wheels. More specifically, the invention is applied in an electronic module dedicated to a wheel to measure at least one operating parameter of said wheel. Background technique [0002] For safety purposes, more and more motor vehicles have monitoring systems that include sensors mounted on each wheel dedicated to measuring parameters of the tires mounted on those wheels, such as pressure or temperature, and using To inform the driver of any abnormal changes in the measured parameters. [0003] These monitoring systems usually have, on the one hand, electronic modules installed on each wheel, which, in addition to the above-mentioned sensors, also contain microprocessors and radio frequency transmitters; A central unit comprising a computer including a radio frequency receiver connected to an antenna. [0004] One of the problems that such a monitoring system needs to solve is that ...
