The invention relates to a method for producing an ultrasound sensor () for a motor vehicle, in which method, for the ultrasound sensor (), a diaphragm () for emitting ultrasound signals in an emitting direction () and a sensor housing () are provided, in and/or on which sensor housing the diaphragm () is fastened, wherein the sensor housing () has a front side (), which points in the emitting direction () of the diaphragm (), and a rear side (), which points in a rearward direction () which is opposite to the emitting direction (), and wherein the sensor housing () is, on the rear side (), formed with a rear-side installation opening () for components of the ultrasound sensor (), wherein the diaphragm () is inserted into the sensor housing () through the rear-side installation opening () in the emitting direction (), and said diaphragm is placed, through an interior space () of the sensor housing (), into an installed position at the front side () of the sensor housing (), and is fastened in the installed position.

Method for producing an ultrasonic sensor for a motor vehicle

A method for producing an ultrasound sensor for a vehicle is disclosed. A diaphragm for emitting ultrasound signals in an emitting direction and a sensor housing are provided for the sensor, where the diaphragm is fastened on the sensor housing, where the housing has a front side, which points in the emitting direction, and a rear side, which points opposite the emitting direction, and where, on the front side, the housing is formed with a front-side opening for the diaphragm, where the front side of the housing is connected to a cap which is composed of a foil and by way of which the front-side opening of the housing is covered in the emitting direction, where the diaphragm is inserted at least regionally into a receptacle of the cap and, a front side of the diaphragm, which points in the emitting direction, is connected to a base of the receptacle.

The invention relates to a sensor arrangement () for detecting a state of a road (), with a sensor device () which is designed to detect an impact of water () on a wheel arch lining () of a motor vehicle () while the motor vehicle () is travelling on the road (), and with a control device () for detecting the state of the road () on the basis of the impact of the water () detected by means of the sensor device (), wherein the sensor device () has a first and a second ultrasound sensor () which are designed in each case to receive an ultrasound signal and which are furthermore designed in each case to detect the impact of the water () on the wheel arch lining (), wherein the first and the second ultrasound sensor () are arranged apart from one another on or in the wheel arch lining ().
