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), characterized in that: the communication device comprises a low-frequency communication interface (BF) and a wireless communication interface (11) using the Bluetooth 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,

said communication system being configured to ensure an exchange of data between the communication device and the at least one mobile device,

the communication device comprising a low-frequency communication interface and a wireless communication interface according to Bluetooth Low Energy (BLE) protocol in an advertising state,

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, and

wherein after a triggering event, the wireless communication interface according to the BLE protocol switches from the advertising state to a scanning state.

2. The communication system as claimed in claim 1, wherein said at least one mobile device is a smartphone 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 a mobile communication and information device (CID) comprising:

a low-frequency communication interface; and

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

4. The system as claimed in claim 1, wherein the triggering event occurs in the motor vehicle.

6. The system as claimed in claim 1, wherein the triggering event is an activation of a handle of a door of the vehicle.

7. The system as claimed in claim 1, wherein the triggering event is an activation of a button for starting, and of the vehicle.

12. The system of claim 1, wherein the mobile device is a smart watch.

5. A method comprising:

an exchange of data between a communication device and at least one mobile device, the communication device comprising a low-frequency communication interface and a wireless communication interface according to Bluetooth Low Energy (BLE) protocol in an advertising state;

after a triggering event in the vehicle, the wireless communication interface according to the BLE protocol switches from the advertising state to a scanning state;

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

after receipt of the signal by a low-frequency communication interface of a mobile communication and information device (CID), a BLE interface of the (CID) switches from a standby state to the advertising state.

8. The method as claimed in claim 5, wherein the triggering event consists of a predetermined time that has elapsed.

9. The method as claimed in claim 5, further comprising after an action on the mobile device, the BLE interface of the mobile device switches into an initiating state.

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

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