| 摘要 |
The invention relates to a method and a device for monitoring signal processing units for sensors which detect the individual process control quantities or process measured values of a process. In order to improve the reliability of the sensor data of a vehicle, an at least redundant processing of the sensor data is carried out in two identical signal processing units ( 43, 31, 46; 44, 32, 45 ), which each have, independently and separately from the other, at least two processing devices ( 43, 44 ) in two evaluation devices ( 31, 32 ), whereby the sensor data are transmitted between the one processing device ( 43, 44 ) and the corresponding evaluation device ( 31, 32 ) through separate signal lines ( 60, 61 ).
