Abstract
A method, a device and a computer program product, by means of which sensor values of redundant sensors in vehicles can be compared with each other to carry out a plausibility check, the measured values of said sensors not being synchronized with each other, are described. On the basis of a first measured value in time, and using the physical properties of the vehicle, a plausibility window, in which a second, subsequent measured value of a different sensor must be to count as plausible, is formed. The determined plausibility of the measured values is indicated by means of a plausibility signal.
