2022 to Present

In 2022, Vector-Drive clearly defined its strategic shift from foundational technology development to full-vehicle R&D. In collaboration with Professor Zhao Hai of Northeastern University and Professor Zhang Hua of Chongqing University, the company introduced the Loong-style modular steer-by-wire intelligent chassis design. Built on E-Corner Module technology, the platform enables steerable high-torque in-wheel motor drive, equivalent continuously variable transmission, millisecond-level control response, and advanced ESP functionality.

2023–2024

Vector-Drive achieved a key technical breakthrough by developing a semi-rigid torsional connection mechanism to replace traditional free articulation. This design keeps the relative angle between tractor and trailer within a safe range. The company also introduced tractor-trailer coordinated vector control, known as Vector Drive, which gives the trailer independent driving force, active steering, and braking capability. As a result, the articulated vehicle can operate with a motion model close to that of an integrated single-body truck.

Academic Recognition

In October 2024, a related paper, Optimization for Fuel Consumption and TCO of a Heavy-Duty Truck with Electricity-Propelled Trailer, was published in Elsevier's Energy Research & Social Science journal. The paper provides academic validation for the energy-saving and total cost of ownership potential of an electricity-propelled trailer configuration.

2025–2026

Vector-Drive further defined its quasi-integrated vehicle architecture: a new category that is legally classified as a tractor-semitrailer, but controlled dynamically as an integrated heavy-duty truck. By retaining the GB1589 fifth-wheel coupling to meet regulatory length requirements, while using semi-rigid connection and vector control to eliminate key dynamic weaknesses, the system achieves a cargo volume of no less than 95 cubic meters, representing a 20% improvement over conventional vehicles.

The company is also advancing a three-party implementation model. Together with GAC Lingcheng, which provides the hydrogen-powered T9 platform and vehicle certification, and Guangzhou Xinyuan, which provides intelligent cargo body integration and logistics scenario access, Vector-Drive has launched the Guangzhou–Zhanjiang Hydrogen Highway Quasi-Integrated Autonomous Driving Demonstration Project. The project has received support from the Guangdong Provincial Development and Reform Commission and the local industry and information technology authorities. Applications are being pursued for autonomous driving test plates and hydrogen-refueling privileges.

International Expansion

On the international front, Vector-Drive plans to explore cooperation with Aurora Innovation by providing a physical foundation for its L4 autonomous driving system. Vector-Drive's steer-by-wire chassis can address Aurora's "trailer black box" challenge in articulated vehicle dynamics, potentially unlocking the retrofit market for approximately 3 million existing heavy-duty trucks in the United States. The proposed cooperation is expected to help Aurora achieve positive cash flow within 18 months.
