Device for Detecting the Impact of an Object on a Vehicle

A device for detecting the impact of an object on a vehicle, comprising:

• a hose filled with a filling medium, wherein the hose has a first end and a second end situated opposite the first end;
• a first pressure sensor connected with the first end of the hose, and a second pressure sensor connected with the second end of the hose, wherein the first and the second pressure sensors each provide a signal representing an internal pressure of the filling medium in the hose;
• an electronic control unit connected by way of connection lines with the first and the second pressure sensor for the exchange of data, wherein the electronic control unit is configured to process the signals received from the first and the second pressure sensor, wherein the hose is sealed off with respect to the environment and the first and the second pressure sensors such that the internal pressure of the filling medium in the hose is independent of an ambient pressure and thereby fluctuates depending on temperature, and wherein the electronic control unit is configured to process temperature-caused changes to the internal pressure during vehicle operation as a criterion for a diagnosis of operability of the device.
