The main characteristics of the driving safety business in the edge cloud Internet of Vehicles business are low latency and high reliability. In terms of latency requirements, assisted driving requires 20-100ms, while autonomous driving requires a latency as low as 3ms. Edge cloud is one of the enabling technologies for low-latency services in existing mobile networks. Mobile multi-access edge computing (Multi-access Edge Computing, MEC) is an open platform that integrates network, computing, storage, and application core capabilities at the edge of the network close to the source of people, things, or data, and provides edge intelligent services nearby to meet The key requirements of industry digitalization in terms of agile connection, real-time business, data optimization, application intelligence, security and privacy protection, etc. Generally speaking, for the IoV scenario, there are two construction methods for the MEC system. One is to use an edge cloud system built by several general-purpose servers on the base station side to complete local offloading of traffic and implant IOV-related applications. The other is to provide a certain computing capability inside the base station. The edge cloud provides localized cloud services and can connect to public clouds or private clouds within other networks to implement hybrid cloud services. Edge cloud computing can provide low-latency services for mobile terminals by sinking the local cloud platform to the base station side. Through the local calculation of the LTE cellular network and the MEC Internet of Vehicles platform, in an emergency, service driving information such as warnings is sent to the vehicle OBU. Compared with the existing network delay, the vehicle-to-vehicle delay can be reduced to less than 20ms, which is greatly reduced. Owner reaction time. In addition, the MEC Internet of Vehicles platform can also realize route optimization analysis, driving and parking guidance, safety auxiliary information push and regional traffic service guidance, etc.
