Automated Vehicle System-Level Simulation and Testing Environment

Designing an Automated Vehicle System-Level Simulation and Testing Environment is a comprehensive endeavor that involves various specialized software, hardware, and integration methodologies.

---

Objective: Design an integrated, system-level simulated environment for a vehicle, emphasizing areas such as battery management, functional safety, vehicle mechatronics, and network management. The system will use automation tools for test scenario execution to ensure robustness, performance, and safety.

Components:

1. Vehicle Dynamics and Environment Simulator:

   • Using Python, create a simulation of vehicle behaviors including driving conditions, terrain, battery consumption, etc.
   • Integrate weather conditions, road conditions, and real-time challenges.

2. Battery Management System (BMS) Simulator:

   • Create a virtual Lithium-Ion and Lead-Acid BMS.
   • Simulate battery behaviors such as charge-discharge cycles, overcharge scenarios, temperature effects, etc.

3. Body Control Simulator:

   • Design virtual actuators to represent vehicle mechatronics like falcon wings, power front doors, etc.
   • Apply scenarios where these mechatronics might malfunction or get stressed.

4. Low Voltage Network Management:

   • Design a simulated low voltage network in a vehicle.
   • Incorporate scenarios where there are network congestions, failures, or security breaches.

5. Low Voltage Network Management:

   • Design a simulated low voltage network in a vehicle.
   • Incorporate scenarios where there are network congestions, failures, or security breaches.

6. Test Automation Infrastructure:

   • Incorporate Jenkins for Continuous Integration (CI) and testing automation.
   • Utilize Docker to containerize the simulation environment ensuring consistent and reproducible test scenarios.

7. Embedded Systems Integration:

   • Design a minimal firmware using C/C++ that would interact with your simulated environment.
   • This firmware can mock the behaviors of an actual vehicle's firmware, responding to different scenarios.

8. Dashboard and Analysis Tool:

   • A user-friendly interface that displays real-time data from the simulation.
   • Incorporate analysis tools that can root-cause issues, analyze battery performance, and check the performance of the vehicle mechatronics.

9. Scenario Execution:

   • Define test scenarios where multiple vehicle components are stressed simultaneously, such as challenging terrains, malfunctioning falcon wings, and a nearly depleted battery.
   • Use the automation infrastructure to run these scenarios and gather results.

Expected Outcomes:

• Ability to simulate complex, real-world scenarios for a vehicle in a controlled environment.
• Data on how different vehicle components behave under various conditions.
• Insights into potential weak points or vulnerabilities in the vehicle's systems.
• Demonstrable expertise in Python, system-level troubleshooting, automation tools, and firmware development.

Additional Considerations:

Scalability: Future-proof the system architecture to accommodate additional components or functionalities.

Real-time Simulation: Ensure simulations are real-time for effective testing and validation.

Validation: Validate models consistently with real-world data sets to ensure reliability and accuracy.
