Simulation and Validation for Robotaxis and Autonomous Vehicles
Simulate Real-World Driving at Scale
Accelerate AV development with high-fidelity simulation.
Overview
The Open Simulation Foundation for Autonomous Driving
NVIDIA brings together reasoning models, 3D neural reconstruction, world foundation models (WFMs), high-fidelity sensor simulation, and closed-loop evaluation to expand scenario coverage, strengthen safety validation, and advance robotaxi and autonomous vehicle development.
Benefits
Why Simulation Matters
Physical test drives cannot cover every edge case or rare weather condition. Simulation lets AV teams generate millions of scenario variations—including conditions that have never occurred in the real world—to test safety before a single mile is driven.
Safety Validation for Robotaxi and Autonomous Vehicle Development
Assess vehicle behavior across rare events, adverse weather, complex traffic, and other safety-critical conditions in controlled simulation environments.
Simulation-Driven Cost Efficiency
Reduce reliance on costly data-collection fleets by generating diverse data for development and testing.
Scalability and Flexibility in AV Simulation Workflows
Optimize sensors, configurations, and autonomy stacks before physical prototyping.
Accelerated AV Development and Validation
Advance from data generation to repeatable testing and validation with greater speed and consistency.
