Abstract (en)
[origin: WO2004061285A1] The invention relates to a method, a computer program and a regulator for regulating a pressure-control valve (200) in a fuel-injection system (700) of an internal combustion engine. Said method comprises the following steps: determination of a provisional current target value with the aid of a nominal pressure-current characteristic curve of pressure-control valves for regulating the pressure-control valve; determination of a deviation by comparing a predefined pressure target value for a fuel accumulator (710) with the actual pressure in the fuel accumulator; determination of a current correction value in accordance with the determined deviation and determination of a corrected current target value by correcting the provisional current target value using the current correction value. The aim of the invention is to permit this type of adaptation of the current target value or this type of adaptation of the pressure-current characteristic curve even in a non-stationary mode of the internal combustion engine. To achieve this, the method is only carried out when the internal combustion engine is operated in an overrun mode.
