Abstract

A method is provided for monitoring at least one sensor of a vehicle, which has means for wireless communication, wherein measured values of the at least one sensor are compared to measured values of at least one comparison vehicle with the aid of the means for wireless communication.

First claim

What is claimed is:

1. A method for monitoring at least one sensor of a vehicle, the vehicle including an arrangement for wireless communication, the method comprising:
transmitting, with the aid of the arrangement for wireless communication, a measured value of the at least one sensor of the vehicle to an arithmetic unit;
comparing, by the arithmetic unit, the measured value of the at least one sensor to measured values of sensors of a plurality of comparison vehicles; and
ascertaining, by the arithmetic unit, whether the at least one sensor is operating in a faulty manner, wherein the arithmetic unit ascertains that the at least one sensor of the vehicle is operating in a faulty manner when the measured values of the at least one sensor of the vehicle deviates by a specifiable value from an average value of the measured values of sensors of the plurality of comparison vehicles.

2. The method as recited in claim 1 , wherein:
the arithmetic unit is a server outside the vehicle.

3. The method as recited in claim 1 , wherein the sensor is one of a humidity sensor, a pressure sensor, a temperature sensor, a brightness sensor, and a rain sensor.

4. A device for monitoring at least one sensor of a vehicle, comprising:
an arithmetic unit; and
an arrangement for wireless communication, wherein a measured value of the at least one sensor of the vehicle is transmitted to the arithmetic unit;
wherein the arithmetic unit is configured to:
compare the measured value of the at least one sensor of the vehicle to measured values of sensors of a plurality of comparison vehicles; and
ascertain whether the at least one sensor is operating in a faulty manner, wherein the arithmetic unit ascertains that the at least one sensor of the vehicle is operating in a faulty manner when the measured values of the at least one sensor of the vehicle deviates by a specifiable value from an average value of the measured values of sensors of the plurality of comparison vehicles.

5. A non-transitory, computer-readable data storage medium storing a computer program having program codes which, when executed on a computer, perform a method for monitoring at least one sensor of a vehicle, the vehicle including an arrangement for wireless communication, the method comprising:
transmitting, with the aid of the arrangement for wireless communication, a measured value of the at least one sensor of the vehicle to an arithmetic unit;
comparing, by the arithmetic unit, the measured value of the at least one sensor to measured values of sensors of a plurality of comparison vehicles; and
ascertaining, by the arithmetic unit, whether the at least one sensor of the vehicle is operating in a faulty manner, wherein the arithmetic unit ascertains that the at least one sensor of the vehicle is operating in a faulty manner when the measured values of the at least one sensor of the vehicle deviates by a specifiable value from an average value of the measured values of sensors of the plurality of comparison vehicles.
