Method for supporting a driver using a portable device in a vehicle
First Claim
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,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, andwherein 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.

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.
