Abstract

A method for managing transmissions, by a motor vehicle, of signals for detecting a device of a user over a wireless communication link. The method includes the steps of requesting activation, by the user of the vehicle, of a so-called “silent” mode in which the transmission of detection signals by the vehicle over the wireless communication link is suspended, it being possible for communication signals generated by a physical entity other than the vehicle to be received by the vehicle, following the activation request, detecting the device of a user outside a predetermined area around the vehicle, activating the silent mode by the vehicle when the device of a user is detected outside the predetermined area, sending to the vehicle, by the user, a signal to deactivate the silent mode from the device so as to reauthorize the transmission of detection signals by the vehicle over the wireless communication link.

Claims (24)

1. A method for managing transmissions, by a motor vehicle, of signals for detecting a device of a user over a wireless communication link, said method comprising:

requesting activation, by the user of the vehicle, of a so-called “silent” mode in which the transmission of detection signals by the vehicle over the wireless communication link is suspended, it being possible for communication signals generated by a physical entity other than the vehicle to be received by said vehicle,

following the activation request, detecting the device of a user outside a predetermined area around the vehicle,

activating said silent mode by the vehicle when the device of a user has been detected outside the predetermined area, and

sending to the vehicle, by the user, a signal to deactivate the silent mode from the user device so as to reauthorize the transmission of detection signals by the vehicle over the wireless communication link,

wherein the activation request is produced by the user from inside the vehicle.

2. The method as claimed in claim 1 , wherein the activation request is produced by the user from inside the vehicle by pressing a button or via a touch screen.

3. The method as claimed in claim 1 , wherein the activation request is produced by the user from inside the vehicle via the device of a user.

4. The method as claimed in claim 1 , wherein the activation request is produced by the user from outside the vehicle via the device of a user.

5. A method for managing transmissions, by a motor vehicle, of signals for detecting a device of a user over a wireless communication link, said method comprising:

requesting activation, by the user of the vehicle, of a so-called “silent” mode in which the transmission of detection signals by the vehicle over the wireless communication link is suspended, it being possible for communication signals generated by a physical entity other than the vehicle to be received by said vehicle,

following the activation request, detecting the device of a user outside a predetermined area around the vehicle,

activating said silent mode by the vehicle when the device of a user has been detected outside the predetermined area, and

sending to the vehicle, by the user, a signal to deactivate the silent mode from the user device so as to reauthorize the transmission of detection signals by the vehicle over the wireless communication link,

wherein the activation of the silent mode by the vehicle is carried out when the device of a user has been detected outside the predetermined area and at the end of a predetermined duration.

6. The method as claimed in claim 1 , wherein the device of a user is an electronic key, a badge or a smartphone.

7. The method as claimed in claim 1 , wherein the signal for deactivating the silent mode is sent over a second wireless communication link or else is generated following the activation of a button of the vehicle.

8. An electronic control module for a motor vehicle, said electronic control module being configured for:

receiving an activation request, produced by the user of the vehicle from inside the vehicle, of a so-called “silent” mode in which the transmission of detection signals by the vehicle over the wireless communication link is suspended, it being possible for communication signals generated by a physical entity other than the vehicle to be received by said vehicle,

following the activation request, detecting the device of a user outside a predetermined area around the vehicle,

activating said silent mode by the vehicle when the device of a user has been detected outside the predetermined area,

receiving a signal for deactivating the silent mode, sent by the user from the device of a user, and

reauthorizing the transmission of detection signals by the vehicle over the wireless communication link when the deactivation signal has been received.

9. A motor vehicle comprising an electronic control module as claimed in claim 8 .
