System for managing a sensor for detecting an intention to open and/or unlock an opening panel of a motor vehicle

A system (100) for managing an intention sensor, the system comprising:

• a long-range detection and authentication module (130) that is intended to be integrated into the motor vehicle (10) and is configured to exchange data with a portable user authentication device (200) so as to detect the arrival of an authenticated user within a perimeter, called wide perimeter (P2);
• a medium-range detection module (110) that is intended to be integrated into the motor vehicle and is able to measure a current distance relative to a portable user authentication device (200) via a two-way communication therewith;
• and
• an intention sensor (120) that is intended to be integrated into the motor vehicle and is able to detect an intention, expressed by a user, to open and/or unlock an opening panel of the motor vehicle;
• characterized in that:
• the medium-range detection module (110) has a standby state and an active state and it is able to receive control data as input for controlling its standby or active state, and, in response, to switch from its standby state to its active state, with said control data depending on the long-range detection and authentication module (130) detecting the arrival of an authenticated user within the wide perimeter (P2);
• in its active state only, the medium-range detection module (110) is configured to carry out successive measurements of current distance relative to the portable user authentication device (200), in order to detect the arrival of the user within a predetermined perimeter (P2), called restricted perimeter;
• the intention sensor (120) has a standby state and an active state and it is configured to detect said intention to open and/or unlock an opening panel when it is in the active state only;
• and
• the intention sensor (120) is able to receive control data as input for controlling its standby or active state, and, in response, to switch from its standby state to its active state, with said control data depending on the medium-range detection module (110) detecting the arrival of the user within the restricted perimeter (P2).
