Summary

A prerequisite for the management of new engine concepts is sufficient information about the cylinder filling, the combustion and the emissions of the combustion engines. Algorithms for the compensation of errors due to a miscalculation of the exhaust gas recirculation rate, the calculation of the engine torque from the crankshaft engine-speed signal and new methods for a fast temperature sensing in the intake pipe as well as the exhaust system are all examples of how the information can be improved. This wider scope of information and its improved quality is the basis for the control functions of the engine. Here especially the control of transient states and other dynamic processes is of growing importance. Thus an adjustment of the governing algorithm to the task is necessary. Due to therefore increasing requirements on the engine management and due to the integration into a vehicle system that is getting more and more complex, the scope of algorithms and the related calibration work will continuously increase. This is why on the one hand broader attention should be paid to “calibratibility” already during the algorithm development phase and on the other hand tools like Rapid Calibration® are necessary in order to benefit from the full calibration potential.
