Abstract

The invention relates to a method for supporting a driver of a motor vehicle (2) while driving the vehicle (2), wherein a sound signal indicating an information generated by a driver assistance system (3) of the vehicle (2) is output by a sound output device (7, 8) of the driver assistance system (3). The method comprises receiving acoustic sound by a microphone of a portable communication device (9) and checking by the portable communication device (9) whether or not the received acoustic sound comprises the sound signal of the driver assistance system (3) as well as, upon detecting the sound signal of the driver assistance system (3), generating a display (15) on a display means (14) of the portable communication device (9) in dependence on the information extracted from the sound signal.

Claims

1. A method for supporting a driver of a motor vehicle while driving the vehicle, wherein a sound signal indicating an information generated by a driver assistance system of the vehicle is output by a sound output device of the driver assistance system, the method comprising:

receiving acoustic sound by a microphone of a portable communication device and checking by the portable communication device whether or not the received acoustic sound comprises the sound signal of the driver assistance system; and

upon detecting the sound signal of the driver assistance system, generating a display on a display means of the portable communication device in dependence on the information extracted from the sound signal.

2. The method according to claim 1, wherein, for supporting the driver while maneuvering the vehicle, a distance between the vehicle and an obstacle external to the vehicle is measured by means of a sensing device of the driver assistance system, wherein the output sound signal indicates the measured distance as the information and the display on the display means of the portable communication device is generated in dependence on the measured distance.

3. The method according to claim 2, wherein the generated display indicates the measured distance.

4. The method according to claim 2, wherein the generated display comprises a vehicle image and a distance indicating image which indicates the measured distance.

5. The method according to claim 4, wherein the distance indicating image comprises bars, the number of which is set in dependence on the distance.

6. The method according to claim 2, wherein the sensing device is an ultrasonic sensor device.

7. The method according to claim 2, wherein the driver assistance system is a park assistant system.

8. The method according to claim 2, wherein to determine the distance based on the sound signal, beeps of the sound signal are detected and a repetition rate of the beeps is determined by the portable communication device.

9. The method according to claim 1, wherein by the portable communication device, it is continuously checked whether or not the sound signal is present in the received acoustic sound, wherein the display is generated upon detecting the sound signal.

10. The method according to claim 1, wherein after generating the display, it is continuously checked by the portable communication device whether or not the sound signal is still present, wherein the display is deactivated, if no sound signal is detected for a predefined period of time.

11. The method according to claim 1, wherein for detecting the sound signal in the received acoustic sound, a comparison signal is provided in the portable communication device and the received acoustic sound is compared with the comparison signal.

12. The method according to claim 11, wherein the comparison signal is downloaded from a data base through the internet for a given vehicle model and/or a vehicle'"'"'s year of manufacture.

13. The method according to claim 1, wherein for detecting the sound signal, a frequency and/or an amplitude of the received acoustic sound is analyzed by the portable communication device to determine whether the amplitude of the received sound at a predefined frequency value is greater than a predefined threshold value.

14. A computer program product which is formed for performing a method according claim 1, when it is executed on a portable communication device.

15. A portable communication device comprising:

a microphone for receiving acoustic sound;

a controller for processing the received sound; and

a display means, wherein the controller is adapted to detect in the received acoustic sound a predefined sound signal of a driver assistance system of a vehicle, to extract information from the sound signal generated by the driver assistance system and to generate a display on the display means in dependence on the information.

16. A system for a motor vehicle, comprising a driver assistance system and a portable communication device according to claim 15.
