Abstract

reconstructing physical values, which cannot be detected directly or only at high costs. Therefore methods from the field of Artificial Intelligence and statistics are combined in a Virtual Artificial Sensor (VAS) to create a basis for important Electrical Control Unit (ECU) algorithms. The influence of databases with an extremely uneven data distribution and data spectrums of high-variance is investigated. Standard measurements from various engines are processed to ensure a high generalizability of the model and the comparability to the results of the ECU. A noticeable increase of robustness against interferences resulting in an improved quality and a reduced parameterization effort is achieved by using the VAS.
