用于确定轨道压力额定值的方法
Abstract:
本发明涉及一种用于为内燃机的高压轨道确定轨道压力额定值(P_Rail_Soll)的方法，其中为了改变轨道压力额定值(P_Rail_Soll)而利用最大梯度(Rail_P_SetPointInc)最大程度地改变轨道压力额定值并且最大梯度(Rail_P_SetPointInc)依赖于内燃机的运行参数而取自特性曲线族(Rail_dpSetPointIncOfs_Map)。运行参数包括换档变速装置的挂入档位(Gearbx_stGear)。
Abstract(English):

Method for the determination of a rail pressure nominal value (P_Rail_Nominal) for a high-pressure rail of an internal combustion engine, wherein the rail pressure nominal value is changed at a maximum using a maximum gradient (Rail_P_SetPointInc) for the modification of the rail pressure nominal value (P_Rail_Nominal), and the maximum gradient (Rail_P_SetPointInc) is taken from an operating point (Rail_dpSetPointIncOfs_Map) as a function of the operating parameters of the internal combustion engine. The operating parameters comprise a shifted gear (Gearbx_stGear) of a gear changing mechanism.
