ANECDOTE

Sony Sensors in Tier IV Platforms

Tier IV partners with Sony to produce automotive-grade cameras using advanced Japanese sensor technology.
These cameras enable wider sensor access beyond traditional OEM Tier 1 supply chains.

ANECDOTE

Nippon Steel's Factory Autonomy

Nippon Steel uses Tier IV autonomy on large flatbeds to move steel beams inside factories.
This industrial use case automates low-value tasks amid labor shortages, enhancing logistics efficiency.

INSIGHT

Scaling Autonomous Buses in Japan

Japan's aging population drives autonomous bus deployments to offset driver shortages.
Tier IV holds roughly 50% municipal contract share under Japan's national Mobility DX plan.

Christian John, President, TIER IV North America joined Grayson Brulte on The Road to Autonomy podcast to discuss how TIER IV is scaling open-source autonomous driving platform software globally.

Tier IV is using the foundational elements of Autoware, an open-source autonomous driving software stack to build scalable, modular reference platforms for everything from robotaxis to autonomous buses and industrial logistics. This open platform approach allows multiple companies to collaborate, innovate, and distribute development costs across the ecosystem, similar to Meta’s open-source LLama model for AI.

In Japan, TIER IV is experiencing particular success with autonomous buses in Japan, where they’ve secured approximately 50% of municipal contracts as part of Japan’s Mobility DX initiative addressing the country’s aging population and driver shortage.

As autonomy scales globally, open-source autonomous driving software could play a vital role. It’s a role that TIER IV wants to play in the global autonomy market.
