METHOD AND DEVICE FOR DETECTING AT LEAST ONE SENSOR MALFUNCTION OF AT LEAST ONE FIRST SENSOR OF AT LEAST ONE FIRST VEHICLE
First Claim
1. A method for detecting at least one sensor malfunction of at least one first sensor of at least one first vehicle, comprising:
- ascertaining at least one first signal by the at least one first sensor of the at least one first vehicle;
comparing the at least one first signal according to predefined comparison criteria to at least one comparison variable;
wherein the at least one first comparison variable is ascertained as a function of at least one further second signal from at least one second sensor of at least one further second vehicle and the at least one sensor malfunction in the at least one first vehicle is detected as a function of the comparison.
