Abstract

The present invention essentially relates to a communication system comprising a communication device mounted in a motor vehicle and at least one mobile device (SP, CID, smart watch), said communication system being intended for providing a data exchange between the communication device and the at least one mobile device (SP, CID, smart watch), characterised in that: the communication device comprises a low-frequency communication interface (BF) and a wireless communication interface (11) using the Blue-tooth Low Energy (BLE) protocol in “advertising” state; and in that the communication device is capable of communicating with said at least one mobile device either in low-frequency mode using the BLE protocol or using only the BLE protocol.

Claims

1. A communication system comprising:

a communication device which is fitted in a motor vehicle; and

at least one mobile device (SP, CID),

said communication system being designed to ensure an exchange of data between the communication device and the at least one mobile device (SP, CID, smart watch),

wherein the communication device comprises a low-frequency communication interface (BF) and a wireless communication interface (I1) according to the Bluetooth Low Energy (BLE) protocol in the advertising state, and wherein the communication device communicates with said at least one mobile device, firstly in low-frequency mode and according to the BLE protocol, and secondly according to the BLE protocol alone.

2. The communication system as claimed in claim 1, wherein said at least one mobile device is a smartphone (SP) comprising a wireless communication interface according to the BLE protocol in the advertising state.

3. The system as claimed in claim 1, wherein said at least one mobile device is an identifier (CID) comprising:

a low-frequency communication interface; and

a wireless communication interface according to the BLE protocol in the standby state.

4. A method for implementation of the system as claimed in claim 1, the method comprising:

a step during which, after a triggering event in the vehicle, the vehicle interface according to the BLE protocol goes from the advertising state to the scanning state.

5. The method as claimed in claim 4, further comprising:

a step in which, after the triggering event, the low-frequency communication interface of the vehicle sends a signal; and

a step in which, after receipt of the signal by the low-frequency communication interface of the identifier (CID), the BLE interface of the identifier (CID) goes from the standby state to the advertising state.

6. The method as claimed in claim 4, wherein the triggering event is the activation of a handle of a door of the vehicle.

7. The method as claimed in claim 4, wherein the triggering event is the activation of a button for starting, and of the vehicle.

8. The method as claimed in claim 5, further comprising a step in which, after a predetermined time has elapsed, the BLE interface of the mobile device goes into the scanning state.

9. The method as claimed in claim 5, further comprising a step in which, after an action on the mobile device (SP, CID, smart watch), the BLE interface of the mobile device (SP, CID, smart watch) goes into the initiating state.

10. The method as claimed in claim 9, wherein mobile device is provided with a tactile interface, and in that the action on the mobile device (SP, smart watch) is activation via the tactile interface.

11. The method as claimed in claim 9, wherein mobile device (CID) is provided with a remote control button, and in that the action on the mobile device (CID) is activation of the remote control button.
