Abstract

A method includes a reading-in step in which at least one sensor signal is read in via an interface to a sensor disposed in the vehicle, the sensor signal representing at least one current parameter of the electronic device and/or of the driver in the vehicle. The method furthermore includes a comparing step in which the sensor signal is compared with at least one stored utilization signal that represents a utilization of the electronic device by the driver while driving the vehicle. The method further includes an outputting step in which a detection signal is outputted if a predetermined correlation exists between the sensor signal and the utilization signal, in order to indicate the detected utilization of the electronic device.

Claims

1. A method for detecting a utilization of an electronic device by a driver of a vehicle, the method comprising:

obtaining, by processing circuitry and from a sensor disposed in the vehicle, at least one sensor signal representing at least one current parameter of at least one of the electronic device and the driver in the vehicle;

comparing, by the processing circuitry, the sensor signal with at least one stored utilization signal that represents the utilization of the electronic device by the driver while driving the vehicle; and

outputting, by the processing circuitry, a detection signal that indicates the utilization of the electronic device in response to a determination, based on the comparing, that a predetermined correlation exists between the sensor signal and the utilization signal.

2. The method of claim 1, wherein the correlation is determined to exit when the sensor signal conforms to the utilization signal within a tolerance range.

3. The method of claim 1, wherein the obtaining includes reading in the sensor signal as at least one of a camera signal furnished by a vehicle camera, an ultrasonic signal furnished by an ultrasonic sensor, a laser signal, and a radar signal furnished by a radar sensor.

6. The method of claim 1, wherein, in the comparing, the stored utilization signal is compared as a three-dimensional laser image signal.

7. The method of claim 1, wherein the obtained signal represents at least one of a position of the driver in the vehicle, a gaze direction of the driver in the vehicle, and a hand movement of the driver in the vehicle.

8. The method of claim 1, wherein the obtained sensor signal is read in as a seat signal furnished by a seat sensor.

9. The method of claim 1, wherein the obtained sensor signal includes a parameter that represents a posture of the driver on a seat.

10. The method of claim 1, wherein, in the comparing, the stored utilization signal is compared as a posture image signal.
