Method and device for localization of the position of a wheel of a vehicle
First Claim
1. A method for localization of a position of a wheel (2) of a vehicle (1), the vehicle being equipped with a central unit (15), a transmitting frontal antenna (13, 14) connected to said central unit, and a transmitting lateral antenna (11, 12) connected to said central unit, said lateral antenna and said frontal antenna placed so as to have coverage zones comprising a common zone in which the wheel (2) to be localized is located, the wheel (2) equipped with an electronic box (6) configured for, upon receiving an identification request signal with a power greater than a predetermined detection threshold, transmitting to the central unit signals representing operational parameters of the wheel and an identification code for the wheel, said method comprising the steps of:
- the central unit simultaneously ordering the transmission by the frontal antenna and the lateral antenna of two identical, in-phase, identification request signals, a power of a combination of the two said identification request signals, within the common zone in which the wheel (2) to be localized is located, being greater than the predetermined detection threshold of the wheel (2); and
the electronic box, of the wheel receiving the combination of the two said identification request signals, responsively transmitting to the central unit the signals representing the operational parameters of the wheel and the identification code for the wheel.

Abstract
The invention relates to a method and a device for localization of the position of a wheel (2) of a vehicle (1). According to the method of the invention, the vehicle (1) is equipped with two transmitting antennas—a lateral antenna (11) and a frontal antenna (13) —placed so as to have coverage zones comprising a common zone in which is located the wheel (2) to be localized, and the transmission by the two transmitting antennas (11 and 13) of two identical, in phase identification request signals of powers suited to obtain in the area of wheel (2) to be localized a resulting signal of power greater than the detection threshold of an electronic box (6) with which said wheel is equipped is ordered simultaneously.
