Abstract (en)
[origin: US2009287389A1] The resolution of output signals from at least one measuring sensor on an internal combustion engine can be increased by: the working level range of the sensor is divided into at least two range sections, each section is provided with the same given output level range limited with relation to the working level range, for the output signal from the sensor and the switching from one to the other section is carried out independently by the sensor, when a range boundary between two adjacent sections is reached, exceeded or fallen below, the operating point of the internal combustion engine is determined by an engine management based on at least one parameter, the time curve for the raw sensor signal is predicted from at least one set of performance characteristics for the current operating point and the engine management determines which section is current from the predicted raw sensor signal time curve.
