<p>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</p> |
