Abstract

The present invention is directed to a method and system for detecting a wireless telephone communication in a vehicle, and once detected, when the vehicle exceeds a predefined speed limit, for generating and sending Dual-Tone Multi Frequency (DTMF) encoded information over the voice channel. The encoded information comprises the values of various physical parameters related to the moving vehicle. For instance, these parameters can include the current time at which the telephone communication started, and optionally, the position of the vehicle. In a particular embodiment, the values of the various parameters are sent at regular time intervals until the communication terminates.

Claims

1. A method for transmitting over a wireless communication, information relative to a moving vehicle, the method comprising the steps of:

detecting a wireless communication with a mobile communication system in the vehicle;

comparing a measured vehicle speed with a threshold; and

when a wireless communication with the mobile communication system in the vehicle is detected and when the measured vehicle speed exceeds the threshold;

encoding information related to the vehicle;

translating the encoded information into Dual Tone Multi Frequency (DTMF) characters; and

transmitting the DTMF characters over the wireless communication.

2. The method according to claim 1, wherein the steps of encoding information related to the vehicle, translating the encoded information into DTMF characters, and transmitting the DTMF characters over the wireless communication are repeated as long as a wireless communication with the mobile communication system in the vehicle is detected and the measured vehicle speed exceeds the threshold.

3. The method according to claim 1, wherein the step of encoding information related to the vehicle, comprises the step of:

encoding a current time, and the vehicle speed measured at the current time.

4. The method according to claim 1, wherein the step of encoding information related to the vehicle, comprises the step of:

encoding an identification of the vehicle.

5. The method according to claim 1, wherein the step of encoding information related to the vehicle, comprises the steps of:

determining a current position of the vehicle; and

encoding the current position.

6. The method according to claim 1, wherein the DTMF characters are transmitted over the wireless communication to a telecommunication service provider, where the DTMF characters are filtered, and information transmitted in the DTMF characters is decoded and recorded.

7. The method according to claim 1, wherein the step of detecting a wireless communication with a mobile communication system in the vehicle comprises the further step of:

detecting a variation of energy emitted by the mobile communication system.

8. The method according to claim 1, wherein the mobile communication system comprises a free hand system and a mobile phone, and wherein the step of detecting a wireless communication with a mobile communication system in the vehicle comprises the further step of:

detecting a variation of energy in an output of the free hand system.

9. The method according to claim 1, wherein the step of transmitting the DTMF characters over the wireless communication, comprises the further steps of:

generating DTMF tones from the DTMF characters; and

playing the DTMF tones using a loudspeaker.

10. A system for transmitting over a wireless communication, information relative to a moving vehicle, comprising:

a system for detecting a wireless communication with a mobile communication system in the vehicle;

a system for comparing a measured vehicle speed with a threshold;

a system for encoding information related to the vehicle, when a wireless communication with the mobile communication system in the vehicle is detected and when the measured vehicle speed exceeds the threshold;

a system for translating the encoded information into Dual Tone Multi Frequency (DTMF) characters; and

a system for transmitting the DTMF characters over the wireless communication.

11. The system according to claim 10, wherein the information related to the vehicle is encoded by the encoding system, the encoded information is translated into DTMF characters by the translating system, and the DTMF characters are transmitted over the wireless communication by the transmitting system, as long as a wireless communication with the mobile communication system in the vehicle is detected and the measured vehicle speed exceeds the threshold.

12. The system according to claim 10, wherein the system for encoding information related to the vehicle encodes a current time and the vehicle speed measured at the current time.

13. The system according to claim 10, wherein the system for encoding information related to the vehicle encodes an identification of the vehicle.

14. The system according to claim 10, wherein the system for encoding information related to the vehicle, comprises:

a system for determining a current position of the vehicle; and

a system for encoding the current position.

15. The system according to claim 10, wherein the transmitting system transmits the DTMF characters over the wireless communication to a telecommunication service provider, the telecommunication server provider further including a system for filtering the DTMF characters, a system for decoding information transmitted in the DTMF characters, and a system for recording the decoded information.

16. The system according to claim 10, wherein the system for detecting a wireless communication with a mobile communication system in the vehicle further comprises:
