Abstract:
1. A method for diagnosis of at least two sensor signals, comprising the steps of: receiving a first signal and at least an equivalent value second signal, and at least when the second signal exhibits a time delay compared to the first signal, taking into account a previous curve of the first signal and/or a previous curve of the second signal, wherein the process of taking account of the previous timing curve of the first signal includes determining a rate of change of the first signal, and the process of taking account of the previous timing curve of the second signal includes determining a rate of change of the second signal, wherein the amount of the difference between a value of the first signal and a value of the second signal is compared with a first adaptive threshold value, wherein the adaptation of the first threshold value is undertaken depending on the rate of change of the first signal and/or depending on the rate of change of the second signal.
