ABSTRACT

With the development of the electric vehicle consumer market, the Internet of vehicles technology, as an important branch of the Internet of things, is developing rapidly. Due to technological and economic progress, and the development of electrification, networking, and intelligence in the automotive industry, vehicle operation and maintenance methods are being gradually upgraded from traditional “fault maintenance” and “regular maintenance” to “conditional maintenance” and “regular maintenance”. Preventive maintenance”. Digital twin technology integrates real-time sensing data, mechanism models, historical information and other data for high-precision analysis and calculation, which can realize high-precision, high-efficiency, high-reliability mapping, and evolution of physical entities. This article is based on the equipment layer, the transmission layer, the application layer as the starting point, the design and development of the electric vehicle chassis system combined with the in-wheel motor technology, ZIGBEE wireless transmission, vehicle failure and health management and other technologies, integrating the intelligent operation and maintenance system based on Web3D, WebGL, Threejs and other technologies, design a vehicle chassis control system based on the Internet of Things technology with digital twin intelligent operation and maintenance functions. The system can visualize the data in the 3D model of the vehicle and perform health management based on the data uploaded by the Internet of vehicles in real time. Users can also interact with the vehicles are operated as an excellent solution for Internet of Vehicles security.
