Use Case: Variant-Based Automation and Configuration

The Task

ECU software is often built to support multiple variants, e.g., different vehicle platforms, engine or gearbox variants. The number of different vehicle versions has been steadily increasing for many years, and with it the number of vehicle and ECU combinations to be tested. Systematic support for variant handling in HIL testing and an established procedure for the development and test of electronic control units (ECUs) is therefore indispensable.

The Challenge

• Handling the rising number of variants
• Automating complex and repetitive HIL and software build preparation workflows
• Managing the flow of data from different development and test tools, and introducing a standardized process

The Solution

The SYNECT API and the software’s versatility allow for the integration of all engineering tools involved in the HIL process, e.g., tools for ECU calibration, ECU flashing, or downloading and parameterizing the real-time application.

The integrated SYNECT variant management provides a systematic approach for defining and handling variants and makes it easy to obtain the correct data, e.g., parameters or tests, for a specific software variant. Fully automated workflows in SYNECT perform all the preparation and configuration steps for the specific variant. SYNECT Workflow management is well established at major OEMs and a range of companies performing ECU tests.
