Embodiment Construction

[0028] figure 1 A plan view of a motor vehicle 1 is schematically shown. A motor vehicle is a passenger vehicle or an autonomous motor vehicle. Motor vehicle 1 travels along road 8 in the direction of travel. The road is bounded by sidewalk 2.

[0029] Furthermore, the road user 3 on the bicycle 7 is also moving on the road in the direction of travel of the motor vehicle 1 . In this case, road users 3 and bicycles 7 are located between motor vehicle 1 and sidewalk 2 . A road user 3 is at risk of being pushed towards the pavement 2 by the vehicle 1 . Therefore, he knocks on the body of the vehicle 1 .

[0030]Motor vehicle 1 is equipped with a sound sensor in the form of a structure-borne sound sensor or knock sensor 4 . The sound sensor 4 is preferably fastened under the tailgate or at various positions above or below the sheet metal of the body. The vehicle also contains a number of parking aid sensors 5 . The parking aid sensor 5 is designed in such a way that in the...

Abstract

A method for operating a motor vehicle (1) having at least one sound sensor (4, 6) for detecting acoustic signals generated outside the vehicle (1) includes the steps of detecting an acoustic signal by means of the sensor (4, 6), 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 (1) in response to the detected warning signal, and carrying out the defined action of the motor vehicle (1) if the speedof the motor vehicle (1) undershoots a defined threshold value and the steering angle of the vehicle (1) exceeds a defined threshold value.

Description

technical field [0001] The invention relates to the detection of an acoustic warning signal, such as a warning call or a knock signal due to a knock on the vehicle body. The warning signal can be triggered by road users outside the vehicle and put at risk by the vehicle. Background technique [0002] Today's passenger vehicles are usually moved by a driver who tries to take into account and coordinate all influences on the road and those from other vehicles through actions and reactions. This process requires the full attention of the driver. This is a huge challenge, as evidenced by the number of accidents. At the same time, autonomous vehicles and driver assistance systems that support safe driving are developed. Examples of these are Lane Keeping Assist (Lane Keeping Assist), Lane Change Assist, Blind Spot Assist (Blind Spot Support), Brake Assist (Active City Braking System) and others. [0003] To date, there are no assistance systems that react to pedestrians or cy...
