Abstract (en)
[origin: EP2011984A2] The method involves extracting characteristic features from a transformed signal, and calculating a rail pressure value based on the features and additional predefined influencing variables. An average rail pressure value is ascertained simultaneously from an output signal of the rail pressure sensor. The average rail pressure value is compared with the calculated rail pressure value, when the calculated rail pressure value deviates from the average rail pressure value by a predefined limiting value by outputting an error signal and storing the error signal in error memory. An independent claim is also included for a computer-readable medium containing a set of instructions for detecting output signal of rail pressure sensor.
