Abstract:
X-in-the-loop (XiL) framework is a validation concept for vehicle product development, which integrates different virtual and physical components to improve the development efficiency. In order to develop and validate an extended validation method based on XiL, Tongji University in Shanghai, China and the Karlsruhe Institute of Technology (KIT) in Karlsruhe, Germany co- performed a feasibility study about an X-in-the-distance-loop demonstration platform. The X-in-the-distance-loop demonstration platform includes a MATLAB/Simulink software platform and geographically distributed equipment (driver simulator, driving electric motor and dynamometer test stand), which are used to conduct bidirectional experiments to test communication of powertrain data between China and Germany. This paper demonstrates the research process of XiL validation with two concrete application examples and documents the influence factors that led to improved data transmission through an analysis of the experiments, which included time delay that occurred in Sino-German communication. This framework and analysis provide a guiding method for geographically distributed research, development and testing, which can be used for powertrain and key components.
