Problems solved by technology

[0012] An obvious solution would consist in using two antennas mounted at the rear of the vehicle in order to obtain the exact position of the sign B by using a triangulation method, but this solution would significantly increase the complexity and cost of the system , which presents the disadvantage of

Embodiment Construction

[0048] The system according to the invention allows the activation of functions of the vehicle from the activation device. In the embodiments described hereinafter, the system allows opening of the trunk of the vehicle. Of course, activating other functions of the vehicle is conceivable, for example starting the vehicle, locking the entrance, etc.

[0049] For this, as figure 2 As schematically illustrated in , the system 1 comprises a vehicle 10 , such as a motor vehicle, and an activation device 20 associated with said vehicle 10 .

[0050] The vehicle 10 comprises a module 12 for activating the opening of the trunk of the vehicle 10 and an omnidirectional antenna 14 mounted in the rear of the vehicle 10 and coupled to said activation module 12 and first activated It is configured to emit (preferably periodically) electromagnetic waves causing an electromagnetic field in an emission space around the vehicle 10 and secondly to receive electromagnetic waves from the activat...

Abstract

The present invention is directed to a process for the detection of a fixed position a predetermined distance from a vehicle (10), an activation function (20) of the vehicle (10). the process makes it possible to compare the values of amplitude according to at least one component of an electromagnetic field induced by an antenna (14) of the vehicle (10) and measured by means of activation (20) during a time interval of detection in order to determine whether the activation means (20) is kept in a position fixed for the duration of the time interval of detection.

Description

technical field [0001] The invention relates generally to the activation of functions of a vehicle, in particular a motor vehicle, and more particularly to the detection of a fixed position of an activation device at a predetermined distance from the vehicle in order to allow the activation of functions of said vehicle. [0002] In particular, the invention may be used in the automotive industry, and more particularly, in "hands-free" systems for locking or unlocking open panels (e.g., doors, trunk, etc.) of a vehicle middle. Background technique [0003] An example of a system for detecting the fixed position of an activation device at a predetermined distance from a vehicle is in figure 1 is illustrated in. Such a system comprises a vehicle V and activation means, in this example in the form of a badge B, for "hands-free" access to the vehicle V. [0004] The vehicle comprises an activation module C (electronic unit) and three omnidirectional antennas coupled to said ac...
