Intelligent control of the automated calibration of engine management systems by using a new calibration process scheduler

The development of engine management systems of the last two decades was characterized by an exponential increase of functionality driven by the increasing emission laws from the legal authorities. This increasing complexity included mainly new control functions and diagnostic functions. Model based functions for closed- and open loop systems have been developed in order to increase the quality of the control quality. In order to adapt those functions easily at different vehicles, engines, transmission and other electronic control systems in the vehicle, the concept of “calibration” of those functions has been established. Based on maps, curves and scalar parameter, the adaptation can be calibrated with those parameters to the characteristic behaviour of the respective actuators and sensors of the system.
