Abstract:
A device for monitoring a least one of a plurality of sensors in a motor vehicle, the sensors generating signals, each of the signals representing a different physical variable, comprising:a first arrangement determining identically defined comparison variables for at least two of the sensors as a function of the signals generated by the at least two of the sensors;a second arrangement determining a reference variable as a function of at least two of the identically defined comparison variables, the reference variable being determined as a function of a variable describing a difference between each one of the at least two of the identically defined comparison variables and the others of the at least two of the identically defined comparison variables, the one of the at least two of the identically defined comparison variables being weighted by the variable describing the difference; anda third arrangement monitoring the at least one of the sensors as function of the reference variable.
