Motor vehicle sensor e.g. air flow sensor, data processing system for engine-electronic control unit, has weighting factor determination device to obtain factor from correlation table or from ratio of processing interval and time interval

摘要

The system has a data storage device with a weighting factor determination device to determine a weighting factor (K) from a correlation table or from a ratio of a processing interval and time interval. An evaluation unit computes a weighted mean value of a processed data and an original data by utilizing the weighting factor. A smoothing process achieved by simulation of a CR filter responds adaptively based on the variation of the processing interval. An initial value of the original data is utilized as an initial value of the processed data. An independent claim is also included for a data processing program stored on a computer readable medium.
