Developments Targeting Hybrid Test Systems for HIL Testing

摘要

In the last years, the aerospace industry has recognized the growing need to improve integration test systems with regard to modularity, scalability, and flexibility, since new aircraft programs are becoming increasingly complex. At the same time, sharing test resources between different programs and introducing new test equipment from different sources and suppliers requires a strong effort. A generic and modular architecture for an open test environment can overcome these issues. A new architecture needs to support hybrid testing, this means testing of real and virtual systems under test and a mixture and exchange of both. Therefore, this type of architecture is used in ongoing projects aiming for new test technologies, not only in the aerospace industry but also in the automotive sector. This paper compares the requirements for a generic and modular test architecture as well as trends and solutions to achieve architectures for hybrid test systems used in the aerospace industry with the requirements for the automotive industry. This is done by investigating typical use cases of both industries. This paper also presents preliminary results aiming for a unified approach that is based on ongoing activities in both industries.
