Abstract

The invention discloses a vehicle-road collaborative vehicle-mounted terminal application system based on LTE-V. In the system, the vehicle maintains wireless short-wave communication with other vehicles and roadside equipment in real time by utilizing the characteristics of low delay and high coverage range of LTE-V communication, and interacts information with a vehicle-road collaborative background server through a 4G network. The method comprises the following steps: receiving real-time state information of other vehicles; The method comprises the following steps of: sensing surrounding traffic conditions by traffic participant real-time information sent by roadside equipment, and judging and analyzing a map road relationship, a road distance and collision time between a vehicle and other traffic participants, traffic signs or events according to the vehicle state information and local lane track point map information; According to different traffic scenes judged by the system, a driver is reminded of different traffic events and early warning information through visualization, so that the driving safety is enhanced, and meanwhile, the traffic efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of Internet of Vehicles, in particular to an LTE-V-based vehicle-road coordination vehicle terminal application system. Background technique [0002] With the rise of vehicle-road collaboration technology and the vigorous development of the Internet of Things / Internet of Vehicles, it is required that the vehicle-mounted positioning service terminal can interact and share information between vehicles and infrastructure, and between vehicles and vehicles. Intelligent collaboration and cooperation, to achieve the goal of optimizing the use of system resources, improving road traffic safety, and alleviating traffic congestion. [0003] With the continuous increase of traffic accidents and traffic congestion, a large number of traffic control and traffic guidance facilities have been applied to the actual road traffic system. The data basis for its normal operation is various types of traffic sensors, but the tra...
