Patent ID: 7894977

Claim:
A method for increasing the resolution of output signals from at least one measuring sensor for an internal combustion engine, comprising the steps of: dividing the working level range of the measuring sensor, within which the level values of its raw sensor signal lie, into at least two measuring range segments, assigning the same predefined output level range of the output signal of the measuring sensor, which is limited compared with the working level range, to each measuring range segment, wherein the measuring sensor switches from one measuring range segment to the other when a measuring range boundary between two adjacent measuring range segments is reached, exceeded, or fallen below, determining the operating point of the internal combustion engine by means of an engine controller based on one or more operating parameters of the internal combustion engine for its combustion process, predicting the temporal profile of the raw sensor signal of the measuring sensor from at least one performance characteristic information item for the currently determined operating point, and determining by the engine controller which measuring range segment of the measuring sensor is currently activated based on this predicted temporal raw sensor signal profile.
