Test house electrics/electronics

in-tech is fully responsible test house operator for the electronic validation of several vehicle models

Testing becomes more and more demanding. From early tests to the last customer-oriented tests on the road, a large number of test steps are necessary. This requires extensive system knowledge and methodological expertise in system integration.

More and more vehicle manufacturers are deciding to outsource the validation of electronic components to a single service provider. With the "test house", the customer supplies the latest software versions during the development phase and is given back the finished test and analysis results.

in-tech took over the complete electrical/electronic validation for several vehicle series for a large German automobile manufacturer as test house operator. In our fully equipped and prototype-safe laboratory and workshop areas, we took care of static and dynamic test platforms such as flash test benches, subsystem and system HiLs as well as vehicle prototypes.

As the responsible test house operator, in-tech was responsible for the complete scope of validation: from test planning to test and project management, measurement technology, platform support, logistics and analysis. The project scope was over 400 man-years, more than 70 platforms were supported and tested at the same time.

Project scope

Platform support: This included upgrading and retrofitting test vehicles and test benches to the respective hardware and software versions to be tested.

Tooling: Supporting and setting up suitable measurement technology & analysis tools

Planning: To provide the test platforms with the latest ECU versions, the team was responsible for hardware planning and logistics. Test planning, implementation planning, and defect management were also within the scope of the project.

Testing: From flash tests on the test bench to validating system functions on a HiL to customer-oriented tests in the vehicle: More than 70 platforms were supported and tested at the same time. An analysis team analyzed the recorded malfunctions.

Project management: Several test managers controlled the entire validation process and error management. An overall project manager controlled the entire project.
