Abstract

The invention discloses an automatic driving system for non-public road based on digital twin technology, and the system comprises an automatic driving cloud server and an automatic driving vehicle, wherein the automatic driving cloud server and the automatic driving vehicle carry out data interaction through a high-speed wireless communication link to transmit vehicle location / attitude information and vehicle control information; the automatic driving cloud server is internally provided with digital twin vehicles, a map module and a vehicle automatic driving algorithm; the automatic driving vehicle comprises a vehicle positioning unit, a vehicle movement controller and an obstacle detection module. The invention can realize a reliable, all-weather working and fully autonomous automatic driving system for a low-speed non-public road vehicle at a low cost. At the same time, a simple and flexible vehicle management and control and remote takeover method is further provided.

Description

technical field [0001] The invention relates to the technical field of automatic driving, in particular to an automatic driving system for private roads based on digital twin technology. Background technique [0002] Low-speed vehicles (less than 30 km / h) running on non-public roads are one of the main scenarios for the current autonomous driving technology. These low-speed vehicles include but are not limited to shuttle buses and logistics vehicles used in parks or transportation hubs , Inspection vehicles used in substations or power plants, AGVs used in intelligent factories, etc. [0003] The autonomous driving systems currently used by autonomous vehicles on non-public roads can all be classified as one of the following two technologies: [0004] 1) Tracking [0005] Signs, such as magnetic nails, magnetic stripes, and route markings, are arranged on the driving road in advance for automatic driving vehicles to identify. Self-driving vehicles recognize these signs th...
