Application of Lightweight Simulation Network in Vehicle System Network Test

Intelligent connected vehicles are highly dependent on cellular networks, but the high incidence of network problems also restricts the development of automotive networking. In order to restore the actual network environment, discover and solve the network problems in advance, this paper introduces the network test scheme of the lightweight simulation network vehicle system, and compares the wireless communications test set scheme and the lightweight simulation network scheme in the laboratory environment. The lightweight simulation network scheme is used to verify the vehicle system function from different network environments, verify the network performance of the vehicle system under different vehicle application scenarios, and comparative test of multiple terminals. Through comprehensive and in-depth test, problems are found, and then the vehicle network system is optimized.
