Chassis vehicle industry applications and challenges

In the multimodal transport system, chassis vehicles are used for short-haul transport between ports and railway freight yards and highway freight hubs. By 2023, major ports around the world are facing a shortage of chassis vehicles, caused by factors such as the interruption of chip supply leading to a decrease in new vehicle production capacity and high temporary storage occupancy rates. North American shipping companies are promoting a "chassis vehicle as a service" model, where users can use mobile devices to query nearby available equipment in real time.
In 2023, China's Qingdao Port will test a new type of autonomous driving chassis vehicle, using Beidou high-precision positioning and 5G remote control technology, which will increase daily turnover efficiency by 2.3 times [2]. However, special container transportation still relies on manual operation, such as the on-site inspection of the power supply status of the refrigeration unit of refrigerated containers.
