Tire pressure monitoring system having a test function for the sensor module

A device for detecting and wirelessly transmitting at least one measurement signal characterizing a state of a vehicle tire of a vehicle, including at least one of a tire pressure and a tire air temperature, comprising:

• at least one sensor module, which is arranged in or on the vehicle tire, having at least one sensor for detecting the measurement signal, and having an apparatus for checking a functional capability of the sensor module;
• an energy store, which supplies the sensor module with electrical energy;
• and
• a test routine arrangement having at least one test routine and an activating arrangement for activating the test routine, the activating arrangement being configured to perform at least one of the following:
• activating a start of the test routine as a function of a field strength of a magnetic field acting in an area of the sensor module,
• activating the start of the test routine as a function of a current flowing through an electric circuit, and
• activating the start of the test routine as a function of an acceleration acting on the sensor module, the acceleration being measured by an acceleration sensor.
