ACOUSTIC WARNING SIGNAL DETECTION FOR MOTOR VEHICLES
First Claim
1. A method comprising:
- operating a sound sensor mounted to an exterior panel of a motor vehicle to detect an impact on the exterior panel; and
operating a driver assistance system to determine a speed and a steering angle of the vehicle, determine whether the speed undershoots a first threshold value and the steering angle exceeds a second threshold value, and carry out an automatic braking and/or steering intervention in response to the impact.

Abstract
A method for operating a motor vehicle having at least one sound sensor for detecting acoustic signals generated outside the vehicle includes the steps of detecting an acoustic signal by means of the sensor, classifying the detected acoustic signal as a warning signal if the detected signal has defined features, determining the speed of the vehicle, determining the steering angle of the vehicle, defining an action to be carried out by the motor vehicle in response to the detected warning signal, and carrying out the defined action if the speed of the motor vehicle undershoots a defined threshold value and the steering angle of the vehicle exceeds a defined threshold value. The defined action may be a steering and/or braking maneuver by the vehicle, and/or may be alerting a driver of the vehicle.

6. A method comprising:
-
operating a sensor of a motor vehicle to detect a sound outside of the vehicle; determining the sound was made by an impact on a vehicle exterior; determining a speed and a steering angle of the vehicle; and carrying out an action by the motor vehicle in response to the sound if the speed undershoots a first threshold value and the steering angle exceeds a second threshold value. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. A motor vehicle comprising:
-
a sound sensor mounted to a body of the vehicle and operative to detect a sound made by an impact on an exterior panel of the body; a signal analysis module determining an amplitude and/or frequency of the sound; and a driver assistance system operative to monitor a speed and a steering angle of the vehicle and to carrying out an action by the motor vehicle in response to the sound if the speed undershoots a first threshold value and the steering angle exceeds a second threshold value. - View Dependent Claims (14, 15, 16)
