The system includes an obstacle detector (1), mounted on a car bumper, and connected to an analysis module (2). The module calculates the distance from the obstacle to the car by analysing the signals generated by the detector. An audio system (3) including loudspeakers is mounted inside the car and connected to the analysis module. A display shows the stations received. The sound generated by the analysis module has a frequency which varies function of the car proximity to the obstacle. |
