Successful cooperation project on virtual validation between ETAS and VIRTUAL VEHICLE

The latest cooperation project between ETAS and VIRTUAL VEHICLE focusing on virtual validation and verification has been successfully completed. The results of this specification project have now been summarized in the final project report and the specifications elaborated will serve as a solid base for a joint development project together with partners from the automotive industry and academia.

VIRTUAL VEHICLE is an international research and development center based in Graz, Austria, that deals with application-oriented vehicle development and future vehicle concepts.

Within the framework of a specification project on “Embedded Systems Design and Functional Safety”, ETAS and VIRTUAL VEHICLE analyzed the requirements for software validation of virtual ECUs as well as for so-called XiL-capable component models.

The background of this project is the continuously increasing complexity within the development of automotive ECUs, subsequently leading to growing efforts for testing, validation, and verification. Hardware-in-the-Loop (HiL) systems offer a well-established alternative to cost-intensive tests in the testbed or in real cars. In addition, software or model-based validation activities (SiL /MiL) can be carried out even before the ECU hardware is available – thus helping to increase the efficient use of narrow timeframes on the HiL system.

However, missing standardized interfaces between virtual ECUs and plant models often hamper fully exploiting the potential of virtual validation and virtualization technologies. Consequently, the successful integration of functional safety measures in the development process also gets more difficult.

Within this specification project, ETAS and VIRTUAL VEHICLE thoroughly analyzed the properties of ECU software, which can be validated and verified virtually without the specific hardware being available. Based on this analysis, both project partners developed requirements for tools enabling virtual validation as well as interfaces to ECU software and plant models.

This cooperation is another example of the continuous commitment of ETAS in the context of virtualization of embedded systems and the development of embedded software. With 20 years experience in the area of model-based development as well as a broad product and service portfolio for all phases of the development process (e.g., ASCET, INTECRIO, ISOLAR-EVE, LABCAR, customized engineering services, and expert consulting), ETAS has proven itself as a reliable and innovative partner in the area of virtual validation and verification.
