Abstract (en)
[origin: WO2014166690A1] The invention proposes a method for operating a common rail system (100) of a motor vehicle, which common rail system has a rail pressure sensor arrangement (140) with at least two signal paths (141a, 141b) and which common rail system can be operated with a maximum admissible rail pressure (Pmax) and with a minimum admissible rail pressure (Pmin). In each case on the basis of a pressure measurement in a rail (150) of the common rail system (100), sensor signals (144a, 144b) are read out via the at least two signal paths (141a, 141b), and a signal deviation value (A) is determined which characterizes a deviation between pressure values (a, b) each determined on the basis of the sensor signals (144a, 144b). The method comprises the steps of reducing the maximum admissible rail pressure (Pmax) by a corrective value to a maximum admissible emergency rail pressure (Pmax,E), and/or increasing the minimum admissible rail pressure (Pmax) by a corrective value to a minimum admissible emergency rail pressure (Pmax,E), if the signal deviation value (A) exceeds a predefined value.
