Abstract

The invention relates to a V2X site in-loop test method and device based on edge computing, and the method comprises the steps: a collection and communication device of a tested vehicle receives a trigger signal transmitted by an MEC test simulator, collects the data of the tested vehicle according to the trigger signal, the MEC test simulator generates background data and sends the background data to the collection and communication device of the tested vehicle, the collection and communication device of the tested vehicle determines the early warning time of the tested vehicle and the relative distance between the tested vehicle and a preset background body during early warning according to the data of the tested vehicle and the background data, and the predicted collision time is determined. The MEC test simulator is introduced on the premise that an existing site test process is not changed, the background data and the trigger signal can be simulated, and the data simulated by the MEC test simulator has the advantage of being controllable in real time, so that the test preparation time is shortened, the test efficiency is improved, and the purpose of reproducing the test process is achieved.

Description

technical field [0001] The invention relates to the technical fields of intelligent networked vehicles and intelligent transportation, in particular to a V2X site-in-the-loop testing method and device based on edge computing. Background technique [0002] V2X (Vehicle to Everything) refers to the installation of a special communication terminal on the vehicle, which can realize data interaction services between the vehicle and other vehicles, roads, pedestrians and the cloud, specifically including V2V (Vehicle ToVehicle, vehicle-to-vehicle connection), V2I (Vehicle To Infrastructure, vehicle and infrastructure connection), V2P (Vehicle To Pedestrian, vehicle and pedestrian connection), V2N (Vehicle To Network, vehicle and network connection). V2X communication supports the exchange of information between the vehicle and the outside world, so that the vehicle can perceive the surrounding environment through the use of on-board sensors and camera systems. When the vehicle per...
