TIER IV has initiated several projects aimed at advancing open-source technology for autonomous and software-defined vehicles. The company joined the Japan Science and Technology Agency (JST) ‘Next-Generation Edge AI Semiconductor Research and Development Project’ to develop a software-defined System-on-Chip (SoC) for Level 4 autonomous driving. Working with the University of Tokyo, the project focuses on creating an AI chip optimized for end-to-end inference, with the goal of open-sourcing design assets and toolchains to support the Autoware platform.

Expanding its involvement in open-source ecosystems, TIER IV also joined OIN 2.0, a patent non-aggression framework managed by the Open Invention Network, to support the development of software-defined vehicles. Additionally, the company is collaborating with Renesas Electronics Corporation to develop an AI-native computing platform.
