SystemDesk generates virtual ECUs for functional tests

November 25, 2014 //By Christoph Hammerschmidt
Version 4.3 of the Systemdesk Autosar tool from dSpace enables function developers and software integrators in the automotive domain to automatically generate virtual Electronic Control Units (V-ECUs) in a development process complying with Autosar R4. Within the dSpace tool chain for virtual safeguarding, V-ECUs facilitate testing of new ECU functions without the need for hardware prototypes.

After integrating the new functions into the ECU application software, developers can use them to generate a V-ECU with just a few clicks. SystemDesk automatically generates and configures the necessary components such as the Autosar runtime environment and basis software components. If necessary, users can adapt the basis software configuration according to their needs. Thus, developers can create specific V-ECUs to test their functions; no specific previous knowledge as to the basis software is necessary.

The benefits: For function tests, virtual ECUs are available earlier than the ECU hardware prototype, because the developer can generate it at its workplace PC. The functional behaviour of V-ECUs is comparable with the behaviour of physical ECUs. In addition, modifications or alterations can be implemented quickly and without much effort. Thus, first functional and integration tests can be carried out already in a very early phase of the development.

V-ECUs generated by SystemDesk are integral parts of the dSpace virtual safeguarding tool chain. They enable comprehensive tests of the functional behaviour on a PC as well as on the dSpace VEOS simulation platform, the dSpace MicroAutoBox II and the RTI Autosar Blockset within the vehicle as well as with the Scalexio HiL simulator. In combination with real-time simulation models the functionality can be tested within realistic scenarios. Existing test scenarios, simulation models, configurations and instruments can be reused, contributing to cost reduction.
