Abstract

The invention relates to a communication system that comprises a vehicle electronic key, a vehicle telecommunication device and a portable telecommunication terminal, the electronic key including a first transmitter and the vehicle including a first receiver, the first transmitter and the first receiver being provided for carrying out the transmission of at least one information request from the electronic key to the vehicle, the vehicle telecommunication device including at least a second transmitter, the portable telecommunication terminal including at least a second receiver, the second transmitter and the second receiver being provided for carrying out the transmission of information from the vehicle to the portable telecommunication terminal, the portable telecommunication terminal being provided for displaying at least a portion of the information on a display member of the portable telecommunication terminal. The invention also relates to an electronic key and to a method for communicating information from a vehicle to a portable telecommunication terminal.

Claims

1. A communication system comprising an electronic key of a vehicle, a telecommunication device of the vehicle, wherein that the communication system comprises a portable telecommunication terminal, the electronic key including a first transmitter and the vehicle including a first receiver, the first transmitter and the first receiver being provided to perform a wireless transmission of at least one information request from the electronic key to the vehicle, characterized in that the telecommunication device of the vehicle including at least one second transmitter, the portable telecommunication terminal including at least one second receiver, the second transmitter and the second receiver being provided to perform a wireless transmission of information from the vehicle to the portable telecommunication terminal, the portable telecommunication terminal being provided for displaying at least a portion of the information on a display element of the portable telecommunication terminal.

2. The communication system as claimed in claim 1, wherein the first transmitter and the first receiver are provided for a short-range wireless communication, notably for a range-less than 500 meters.

3. The communication system as claimed in claim 1, wherein the second transmitter and the second receiver are provided for a short-range wireless communication, notably for a range-less than 500 meters, notably a communication according to a WLAN (Wireless Local Area Network) and/or WIGWAM (Wireless Gigabit With Advanced Multimedia support) and/or Bluetooth standard.

4. The communication system as claimed in claim 1, wherein the second transmitter and the second receiver are provided for a communication in a cellular radio communication network, notably of the GSM (Global System for Mobile communications) type and/or of the UMTS (Universal Mobile Telecommunications System) type.

5. The communication system as claimed in claim 1, wherein the information is provided as security information, notably concerning the interior and/or the exterior of the vehicle, and/or as technical information and/or as comfort information.

6. The communication system as claimed in claim 1, wherein the electronic key includes an actuating element for the transmission of the information request from the electronic key to the vehicle.

7. The communication system as claimed in claim 1, characterized in that the telecommunication device of the vehicle and/or the portable telecommunication terminal includes a selection means for determining the information received and displayed by the portable telecommunication terminal and/or for determining the order of display of the information by the portable telecommunication terminal.

8. An electronic key for use in a communication system as claimed in claim 1.

9. The electronic key as claimed in claim 8, wherein the electronic key includes an actuating element for the transmission of the information request from the electronic key to the vehicle.

10. A method for communicating information from a vehicle to a portable telecommunication terminal, by using a communication system as claimed in claim 1, wherein

in a first step, the information request is transmitted from the electronic key to the telecommunication device of the vehicle, via the first transmitter and the first receiver,

in a second step, the information is transmitted from the telecommunication device of the vehicle to the portable telecommunication terminal via the second transmitter and the second receiver,

in a third step, the information is displayed by the display element of the portable telecommunication terminal.

11. The method for communicating information as claimed in claim 10, wherein in a fourth step which is situated in time before the first step, a selection for determining the information to be transmitted to the portable telecommunication terminal is made on the telecommunication device of the vehicle and/or a determination of the order of display of the information by the portable telecommunication terminal is made on the telecommunication device of the vehicle and/or on the portable telecommunication terminal.

12. The communication system as claimed in claim 2, wherein the first transmitter and the first receiver are provided for a short-range wireless communication, notably for a range-less than 150 meters.

13. The communication system as claimed in claim 12, wherein the first transmitter and the first receiver are provided for a short-range wireless communication, notably for a range-less than 50 meters.

14. The communication system as claimed in claim 1, wherein the second transmitter and the second receiver are provided for a short-range wireless communication, notably for a range-less than 150 meters.

15. The communication system as claimed in claim 14, wherein the second transmitter and the second receiver are provided for a short-range wireless communication, notably for a range-less than 50 meters.
