Calibrating AUTOSAR-based ECUs using Siemens’ Capital VSTAR products and XCP
The calibration process of an electronic control unit (ECU) is designed to find optimal values for ECU parameters. This process is an essential element in the development process and has become a critical aspect of overall vehicle performance and behaviors. The main challenges in calibrating complex ECUs are calibration parameters, work-split between entities and model variants for different vehicles. Accordingly, companies require solutions that combine human expertise and easy data handling to manage complex calibration tasks. In this white paper we introduce an efficient toolchain for performing calibration and measurement processes that facilitate adapting vehicle systems to a variety of vehicle models or system variants. Additionally, we explain the required data model in different
parts of the toolchain.
