Abstract
The present invention relates to a method and a device for monitoring sensors that sense in each case individual reference variables or measured variables (A, B, C) relating to a process ( ), which are especially suited for an electronic stability program (ESP) for vehicles. A particularly high degree of reliability is achieved by monitoring the course of the output signals of the individual sensors in a cyclical and sequential fashion in that analytical redundancies are produced from process reference variables and process measured variables (A, B) which are currently not being monitored by means of a multi-process model ( ) for a normal operational mode, and a residuum ( ) is formed of the redundancies along with the output signal being currently monitored. After evaluation of the residuum ( ) and comparison with a threshold value ( ), a fault signal (F) is generated when the residuum reaches the threshold value.
