# TIER IV 與 Yamato Transport 和 Mitsubishi Fuso 合作，測試 Level 2+ 半掛卡車以實現長途自動化物流

, /PRNewswire/ -- TIER IV, the pioneering force behind open-source software for autonomous driving, has completed proof of concept tests for long-haul autonomous trucking with Yamato Transport Co., Ltd. (Yamato Transport) and Mitsubishi Fuso Truck and Bus Corporation (MFTBC), as part of a Japanese government initiative. The tests evaluated vehicle performance, safety protocols and operational workflows, with customer freight transported on a semi-trailer truck equipped with Level 2+ technology. The data and operational insights gathered will be used to refine autonomous driving technology, with the ultimate goal of integrating Level 4 trucks into Yamato Group's long-haul transportation routes.

**Overview**

-   Period: February 16-20, 2026
-   Route: Haneda Chronogate Base (Tokyo) – Kansai Gateway Base (Osaka). Two round trips (four legs) of the about 500-km route were completed. The truck operated at Level 2+ for 100 km on the Shin-Tomei Expressway between two service areas in Shizuoka Prefecture.

**Evaluation scope**

-   Vehicle performance and safety
    -   Collection of trailer motion data, including sway and articulation trajectories.
    -   Performance verification, tracking hands-off duration and lane-keeping accuracy.
    -   Analysis of surrounding conditions, driver decision-making criteria and other factors linked to manual interventions.
-   Travel time
    -   Confirmation that schedules were maintained during Level 2+ driving as reliably as during manual operations, without delays.
-   Operational workflows
    -   Trials of systems that automate parts of the pre-trip inspection, such as tire pressure checks.
    -   Remote monitoring of vehicle status and surroundings to prepare for future Level 4 operations.

**Driver testimonial**

"There was a bit of a learning curve at first, but once I understood how the system behaves, I felt at ease. Looking ahead, I hope autonomous trucks become a reliable partner for us, helping to maintain our hauling capacity."
