US 2026/0208752 A1 · METHOD FOR CHECKING THE PLAUSIBILITY OF A PARAMETER

Abstract

The invention relates to a method for checking the plausibility of a parameter involved in operation of a vehicle system, where the plausibility of the parameter sensed by a first sensor is checked by means of a second sensor, which likewise senses the parameter, by the examination of a first sensor signal (n(S1)) from the first sensor with a second sensor signal (n(S2)) from the second sensor. To make checking of the plausibility as reliable as possible, a differential signal (Δn) between the first sensor signal (n(S1)) and the second sensor signal (n(S2)) is formed and is compared with at least one threshold value (thd1, thd2). A measure is taken if the differential signal (Δn) exceeds the at least one threshold value (thd1, thd2) continuously for longer than a particular amount of time (tft1, tft2) associated with the at least one threshold value (thd1, thd2).

A method for checking the plausibility of a parameter involved in operation of a vehicle system of a motor vehicle, comprising:

checking the plausibility of the parameter sensed by a first sensor by means of a second sensor, wherein the second sensor likewise senses the parameter, by the examination of a first sensor signal (n(S1)) from the first sensor with a second sensor signal (n(S2)) from the second sensor wherein checking the plausibility comprises:
forming a differential signal (Δn) between the first sensor signal (n(S1)) and the second sensor signal (n(S2));
comparing the differential signal with at least one threshold value (thd1, thd2);
and
determining that the differential signal (Δn) exceeds the at least one threshold value (thd1, thd2) continuously for longer than a particular amount of time (tft1, tft2) associated with the at least one threshold value (thd1, thd2);
and
taking a measure.
