Abstract
A device to monitor sensors in a motor vehicle, with the sensors generating signals that each represent different physical variables is provided. The device has a first arrangement with which identically defined comparison variables for the sensors are determined for at least two sensors on the basis of at least the signals generated by them. Furthermore, the device has a second arrangement with which monitoring is performed for at least one sensor, with the monitoring being performed at least as a function of a sensor reference variable determined for the sensor, the signal generated with the sensor and a respective threshold value. In addition, this device has a second arrangement with which a variable is determined at least as a function of at least two of the identically defined comparison variables and is taken into account in forming the threshold value.
