Measuring and calibrating of AUTOSAR applications with XCP and CANape: The AUTOSAR Standard describes methods that enable standardized development of reusable and replaceable software components within vehicles. This approach minimizes the development effort for electronic control unit (ECU) software. The software is then optimized using CANape. Since the software developer cannot yet optimize the parameters for a control algorithm of the ECU at the time of implementation, these parameters are defined in the software as calibration parameters. The calibration parameters are ultimately variables in the source code that reside in RAM memory and remain unchanged by the algorithm itself. They can then be calibrated using CANape.
