Heavy-duty Autonomous Vehicle——HAV
Overview
As unmanned driving accelerates its implementation in enclosed sites and trunk road scenarios, ports—pioneers in unmanned operations—present unique and complex challenges that demand advanced technological solutions for unmanned operations. To address the practical hurdles encountered during the substantive deployment of port unmanned systems, Jingwei Hirain, leveraging its profound expertise and extensive experience in autonomous driving, has developed the 3rd-Generation Heavy-duty Autonomous Vehicle (HAV).
The 3rd-Generation HAV delivers comprehensive enhancements in chassis performance, reliability, and cost-efficiency. It is engineered to provide robust support for full-scenario unmanned horizontal transportation in ports while achieving dual improvements in operational economy and efficiency.
