Robotaxi Safety Must Be Built In From the Design Stage, Not Patched On Afterward

As the robotaxi industry moves beyond the prototype stage into commercialization, proving the reliability of the entire system—beyond simple perception and decision-making capabilities—has emerged as a key challenge.

To address this problem, NVIDIA has introduced NVIDIA Halos, an integrated safety system built on the NVIDIA DRIVE Hyperion platform. Halos aims to simultaneously solve the four core challenges facing robotaxis: a safety-certified OS, standardized interfaces, AI equipped with verifiable guardrails, and large-scale validation.

Halos Core is the next-generation NVIDIA DriveOS, providing a safe OS foundation certified to ISO 26262 ASIL D. Through a hypervisor, it isolates safety-critical functions from general functions to prevent faults from spreading to vehicle control units, and it supports the TensorRT Edge-LLM framework.

The Halos SDK processes data from various sensors—such as cameras, lidar, and radar—in a standardized way through a sensor abstraction layer. This helps enable rapid integration and scaling without the need to rewrite application code every time the hardware changes.
