Automotive Software Architectures: Degradation and Fault Diagnosis
Our demonstrator illustrates how a software architecture responds reliably and securely to the failure of individual modules.
In the demonstration, camera or microphone sensors can be deactivated on demand.
Das System passt daraufhin gezielt seine Funktionen an: Es wechselt auf einen robusteren Planungsalgorithmus, reduziert die Fahrgeschwindigkeit und stellt entsprechende Fehlercodes bereit. This principle can be universally applied to numerous data-processing software components.
Service-Oriented Architectures: Examplaric Integration and Safety Assurance
Using a structured integration methodology, we integrate various functions into a service-oriented architecture. Standardized interfaces ensure efficient and reliable communication between services. An evaluation methodology for AI-supported audio processing is also presented. Functions such as distress call and siren detection increase comfort and safety in autonomous shuttles, thereby boosting user acceptance.
Automotive Software with ASOA: Declarative Orchestration
Our ASOA middleware enables software architectures to be dynamically created and adapted at runtime. Our demonstrator shows how chains of effects can be flexibly constructed and changed as needed – for example, after a cold start, in the event of failures, or when environmental requirements change.
Universal Automotive Bus: Real-time Plug & Play for E/E
Ein interaktiver Hardware-in-the-Loop-Aufbau verbindet reale Steuergeräte und Sensoren mit einer virtuellen Fahrzeugumgebung. Unser Demonstrator zeigt anschaulich, wie sich Komponenten über den Universal Automotive Bus (UAB) integrieren und testen lassen – realistisch, flexibel und effizient.
Deterministic Communication: Recuperation Balancing
Our demonstrator illustrates the development of deterministic software for safety-critical systems using the example of “recuperation balancing.” With the SL-LET methodology and AUTOSAR standards (Adaptive and Classic), we combine agile development, service-oriented architectures, and signal-based systems.
Secure Vehicle Architecture: Open Modular and Certifiable
Our demonstrator shows how secure communication is implemented in an open, service-oriented software architecture. A modular security solution prevents unauthorized access – demonstrated by a simulated driving maneuver by a potential attacker. Communication is based on our own certifiable DDS implementation. All security functions are flexibly configurable and can be controlled via touchscreen.
Simulation-Based vECU and V2X Testing: Efficient and Scalable
With the IPG CarMaker simulation environment, we enable virtual electronic control unit (vECU) evaluation and standard-compliant vehicle-to-everything (V2X) communication. In combination with the digital traffic twin, hereby driving functions can be tested efficiently and scalably.
Info Bee: Mobile Sensor
Our “Info Bee” is a mobile sensor carrier that transmits live images to the control room. In the event of accidents, large-scale events, or demonstrations, the drone assists in assessing the situation, enabling faster and more informed decisions.
