Teaching Design of HIL Simulation Testing System Based on 5G Parallel Driving System

With the rapid development of 5G communication technology, parallel driving systems are gradually being widely applied in the field of intelligent transportation. However, how to efficiently test and validate 5G parallel driving systems, especially in the teaching process, still faces enormous challenges. This article proposes a teaching design based on Hardware in the Loop (HIL) simulation testing to address this issue, in order to support the efficient testing and teaching needs of 5G parallel driving systems. Firstly, the article establishes an HIL simulation testing platform that integrates 5G communication modules to simulate the actual operating environment of vehicles; next, the article adopts a combination of virtual and real methods to interact the simulation environment with physical hardware, enabling students to intuitively understand the working mechanism of parallel driving through experiments; then, through modular design, the article makes the teaching system have good scalability and operability, making it easy to adapt to different teaching scenarios. The experimental results show that after three repeated trainings, the average time for students to complete the task dropped from 25.3 s to 18.7 s (a decrease of 26.1%), the operation error rate dropped from 12.3% to 4.5%, and the communication delay in the system performance and reliability test was stable within 25–60 ms, and the packet loss rate remained below 1%, showing high stability and reliability. The research results prove the effectiveness of the simulation platform in teaching and highlight the advantages of HIL simulation testing.
