The company
Continental develops pioneering technologies and services for sustainable and connected mobility of people and their goods. Founded in 1871, the technology company offers safe, efficient, intelligent, and affordable solutions for vehicles, machines, traffic and transportation.
The challenge
Continental was nominated by a German OEM for the development and integration of an ADAS ECU designed for SAE Level 2/2+ driving functions.
The hardware-in-the-loop (HiL) systems were required to (re)simulate the data communication of the surrounding ECUs by replaying test drive data to Continental’s ADAS ECU. The HiL-enabled tests covered:
- Functional integration tests (FIT)
- Performance KPI tests under realistic (and extreme) load
- Endurance and stability tests
Constraints:
- Developing and delivering a fully operational solution in a short time in parallel to the dynamic ECU development.
- Replay of service-based and non-service-based Ethernet communication including secure data communication protocols such as E2E, SecOc, TLS/DTLS encryption.
- Manipulation of input data to support complex test scenarios.
- Monitoring of ECU output signals to automatically assess test results and support signal visualization for testers.
The solution
Holistic replay HiL solution:
- Time-synchronized, highly precise re-injection of 8x Automotive Ethernet (1Gbit, 100Mbit) and 1x CAN streams.
- ADTF-based solution which can be tailored to the test cases by adapting the configuration or even extending the functionality by the customer’s own ADTF filters.
- Self-assessment of high-quality data replay using Elektrobit’s “Precision & Correctness report”.
- Highly skilled, dedicated project team closely interacting with the customer to support the ECU development with flexible feature implementation and valuable feedback on ECU software implementation.
Benefits:
- Easy adaptation of the data HiL configuration to support both variants of the developed ECU (3x or 8x Automotive ETH injection) and beyond.
- Remote control of HiL systems for scheduling of data replay or software deployment jobs, also within CI/CD/CT.
- Future extendibility for technologies such as, for instance, camera interfaces (GMSL, FPD-Link).
Elektrobit’s added value
High-performant and reliable data replay systems that leverage our decades of experience within automotive software and hardware including agile support of the needs of the parallel ECU development.
Statement by Uwe Kuckelkorn
I would like to share a big “Thank you” with the whole team of Elektrobit. Thank you for the trustful collaboration and the smooth project execution. As always, the Elektrobit team showed its very good and profound skills, knowledge and reliability!
