Sensor for motor vehicle has reference sensor for recording and monitoring of variable disturbance of sensor and by recording variable disturbance of measuring signal of sensor, system is put in secure and given state

摘要

The sensor device has reference sensor (2) for recording and monitoring of the variable disturbance of the sensor (1). By recording the variable disturbance of the measuring signal of the sensor, the system is set in a secure and a given state, before the variable disturbance controls the measuring signal of the sensor. An independent claim is also included for the method for the application of the sensor device.
