Thesis Work:30 hp - Build a Fast Closed-Loop Simulator on GPU for Autonomous Driving

Introduction:
Thesis work is an excellent way to get closer to Scania and build relationships for the future. Many of today's employees began their Scania career with their degree project.

Background:
Recent research has shown that GPU-accelerated simulators enable much faster training of driving agents compared to traditional CPU-based methods. Open-source simulators exist, but they may not be mature enough or easy to adapt to our data. We therefore propose building a lightweight but extensible in-house tool, focused on object-level closed-loop simulation, as a foundation for future work.

Objective:
The thesis project will design and implement a fast closed-loop simulator running on GPU, capable of:

• Efficiently simulating simple object interactions (vehicles, obstacles, etc.).
• Integrating with our data format.
• Providing a clean interface for agent training.

The focus is on creating a minimal, well-engineered prototype that can later be extended.

Potential research questions:

• What level of abstraction is sufficient to achieve both speed and training utility?
• How can GPU execution be structured for scalability and extensibility?
• What trade-offs exist between simulator fidelity and throughput?

Work description

The project will include:

• Surveying existing GPU-based simulators.
• Defining a minimal input/output structure for scenarios.
• Implementing a GPU-first simulator core.
• Evaluating performance and comparing against a CPU baseline.
• Documenting the design and providing guidelines for extensions.
