Robotaxi and Autonomous Vehicle Safety
A full-stack, comprehensive safety system for robotaxis and AVs.
Overview
Safety, From the Cloud to the Car
NVIDIA Halos is a full-stack, comprehensive safety system that unifies safety elements across vehicle architecture, AI models, chips, software, tools, and services to ensure the safe development and deployment of robotaxis and autonomous vehicles (AVs), from cloud to car.
The system covers the full development lifecycle with design-time, deployment-time, and validation-time guardrails that collectively build safety and explainability into AI-based AV stacks. These guardrails are implemented using three powerful computers—NVIDIA DGX™ for model training, NVIDIA Omniverse™ and Cosmos™ for simulation, and NVIDIA DRIVE AGX™ for deployment. At the heart of the vehicle, NVIDIA Halos OS provides the unified software foundation necessary to bridge these AI capabilities with production-ready safety.
NVIDIA Halos complements existing industry-standard safety practices, while introducing unique elements for autonomous vehicles. This ensures regulatory compliance and advances safe and reliable AV stacks, together with NVIDIA’s Halos AI Systems Inspection Lab.
Halos is also extending its comprehensive safety framework beyond AVs to robotics, further enhancing the reliability and safety of intelligent systems.
Highlights
Autonomous Vehicle Safety Leadership
NVIDIA Halos is the result of continuous investment in autonomous vehicle safety—from research to engineering to active engagement with international safety standards—validated by independent third-party assessments.
Technology
Engineered for Safety, Designed for Trust
As AV companies transition to AI-based, end-to-end architectures, NVIDIA Halos provides the critical safety foundation to ensure system-level reliability and iterative improvement for automated driving systems. This includes integration of third party-assessed hardware, software, and processes with a diverse algorithmic architecture and validation pipelines.
Benefits
A Comprehensive System for Autonomous Vehicle Safety
NVIDIA Halos helps to ensure AI-driven AV systems are safe and secure. Partners can tap into NVIDIA’s investments in AI safety to accelerate development and enhance AV reliability. NVIDIA Halos is also open to developers, enabling adoption or customization of safety elements to drive the shared mission to create safe and reliable autonomous vehicle technology.
Design-time, deployment-time, and validation-time guardrails collectively build safety and explainability into several layers of technologies spanning platform safety, AI algorithmic safety, and ecosystem safety.
At the top of the NVIDIA Halos elements sits the NVIDIA Halos AI Systems Inspection Lab, which allows customers and ecosystem partners to verify the safe integration of their products with NVIDIA Halos elements. The lab is the first worldwide program to be accredited by ANAB for AI functional safety.

Platform Safety
The robust foundation for autonomous driving systems includes:
- A System-on-a-Chip (SoC) that’s designed for safety, with hundreds of built-in safety mechanisms.
- NVIDIA Halos OS extends deployment-time safety into the vehicle software stack with certified core software, safe interfaces, and deterministic AI guardrails. See the Halos OS tab for full details.
- A safety-assessed base platform that delivers the foundational safe computer needed to enable safe systems for all types of applications.
- NVIDIA DRIVE Hyperion™,a diverse hardware platform that connects the SoC, OS, and sensors in a vehicle architecture. This enables a vehicle to safely execute contingency plans if needed.
Halos OS
NVIDIA Halos OS is a unified, production-ready software foundation for AI-driven vehicles, built on three in-vehicle software layers and a cloud-side infrastructure layer:
- Halos Core, built on ISO 26262 ASIL D certified DriveOS™, with a hypervisor that isolates safety-critical functions from AI workloads and safety-certified support for CUDA™ and TensorRT™.
- Halos SDK, a middleware layer with sensor and vehicle abstraction, deterministic scheduling, and zero-copy inter-process communication.
- Halos Applications, rule-based safety guardrails for AI, including the NVIDIA DRIVE™ active safety stack (automatic emergency braking, lane departure warning, blind spot monitoring, collision warning), world model perception, and support for NVIDIA Alpamayo end-to-end models.
- Halos Workflow is the cloud-side development infrastructure connecting NVIDIA DGX, NVIDIA Omniverse on OVX™, and NVIDIA AGX™ into a unified development lifecycle. It underpins the Halos Safety Evaluation Framework (SEF) — providing the tools and guidelines needed to build credible safety cases from L2 ADAS to L4 robotaxis.
