Abstract

The invention provides an electromagnetic anti-interference performance test system and method for an intelligent networked automobile. The system comprises a networked system part, an intelligent system part and / or an electromagnetic disturbance part. The networked system part activates a automobile-mounted V2X module and a navigation module respectively through a communication comprehensive tester and a satellite signal generator, a data collector collects the automobile networked system data, and the intelligent system part simulates a road scene through a radar target simulator and a videoplaying device and activates an automobile-mounted millimeter wave radar and an ADAS camera separately. A test device for activating the intelligent networked system needs to simulate the same road scene and synchronize in real time. According to the invention, the electromagnetic anti-interference performance of the whole automobile is tested in an anechoic chamber in a single automobile intelligence and Internet of automobiles technology fusion scheme, and the electromagnetic compatibility problem existing in the system is discovered at the research and development stage of the intelligentnetworked automobile, so that the functional safety of the automobile is improved, and the automatic driving performance of the automobile is improved.

Description

technical field [0001] The invention relates to the field of automobile electromagnetic compatibility testing, in particular to a system and method for testing the electromagnetic immunity performance of intelligent networked automobiles. Background technique [0002] Intelligent networked vehicles are the carrier of unmanned driving technology. To achieve unmanned driving, the integration of bicycle intelligence and Internet of Vehicles technology is the development trend of unmanned driving technology. However, there is currently no mass-produced model of intelligent networked integration. [0003] Due to the development of intelligent network connection of automobiles, intelligent network connection vehicles will be equipped with dozens of communication transmission modules, dozens or hundreds of sensors, hundreds of control units, and several kilometers of cables. The electromagnetic compatibility risks brought by it are obvious. . In addition, intelligent networked veh...
