    • According to the invention, the resolution of output signals (SS) from at least one measuring sensor (DS) on an internal combustion engine (CE) can be increased by carrying out the following steps: the working level range (PZ) of the measuring sensor (DS), within which the level values of the raw sensor signal (ZS) lie, is divided into at least two measuring range sections (A, B), each measuring range section (A, B) is provided with the same given output level range (ASB) limited with relation to the working level range (PZ), for the output signal (SS) from the measuring sensor (DS) and the switching from one to the other measuring range section (A, B) is carried out independently by the measuring sensor (DS), when a measuring range boundary (G1) between two adjacent measuring range sections (A, B) is reached, exceeded or fallen below, the operating point (BP) of the internal combustion engine (CE) is determined by means of an engine management (ECU) based on at least one operating parameter (N, TPS) for the combustion process thereof, the time curve (EPD) for the raw sensor signal from the measuring sensor (DS) is predicted from at least one set of performance characteristics (KI) for the currently determined operating point (BP) and the engine management (ECU) determines which measuring range section (A, B) of the measuring sensor (DS) is current from said predicted raw sensor signal time curve (EPD). ® KIPO & WIPO 2009
    • 根据本发明,可以通过执行以下步骤来增加来自内燃机(CE)上的至少一个测量传感器(DS)的输出信号(SS)的分辨率:测量的工作电平范围(PZ) 传感器(DS),其中原始传感器信号(ZS)的电平值位于其中,被分成至少两个测量范围部分(A,B),每个测量范围部分(A,B)都具有相同的给定 对于来自测量传感器(DS)的输出信号(SS)和从一个切换到另一个测量范围部分(A,B)的工作电平范围(PZ),输出电平范围(ASB) 在两个相邻的测量范围部分(A,B)之间的测量范围边界(G1)达到或超过或低于该值时,内燃机(CE)的工作点(BP) )通过基于至少一个操作参数的发动机管理(ECU)来确定 用于其燃烧过程的调节器(N,TPS),来自测量传感器(DS)的原始传感器信号的时间曲线(EPD)从当前确定的工作点的至少一组性能特征(KI) BP),并且发动机管理(ECU)根据所述预测的原始传感器信号时间曲线(EPD)确定测量传感器(DS)的哪个测量范围部分(A,B)是当前的。 ®KIPO&WIPO 2009
