摘要：

为实现ADAS系统的仿真测试，解决传统实车验证存在的测试成本高、周期长、场景不可复用、无法定量分析等问题，设计实现面向SAE 2级的智能网联汽车系统级测试平台。提出利用PreScan软件进行交通场景仿真及虚拟传感器建模、CarSim软件进行车辆动力学建模，建立涵盖真实底盘执行系统的测试平台方案。基于ISO 15622中定义的典型工况进行仿真分析，搭建ACC功能涉及的Cut-off虚拟交通场景；基于试验数据，对车辆动力学及虚拟传感器进行参数化建模；测量HWT时间，实现法规要求参数的定量分析。构建的测试平台能够为ADAS系统提供完整的“人-车-路”仿真测试环境，为国内进行ADAS系统测试评价提供一个良好的研究平台。

Abstract: In order to realize the simulation test of ADAS system and solve the problems such as high test cost, long cycle, non-reusable scenario, and non-quantitative analysis in traditional real vehicle verification, an intelligent connected vehicle system-level test platform for SAE Level 2 is designed. PreScan software is used for traffic scene simulation and virtual sensor modeling, CarSim software is used for vehicle dynamics modeling, and a test platform scheme covering the real chassis execution system is established. The simulation analysis is carried out based on the typical working conditions defined in ISO 15622, build a Cut-off virtual traffic scenario involving ACC functions. Based on the experimental data, the parametric modeling of vehicle dynamics and virtual sensors is set up. Measure HWT time, and the quantitative analysis of parameters required by regulations is realized. The built test platform can provide a complete "human-vehicle-road" simulation testing environment for ADAS systems, and provide a good research platform for domestic ADAS system testing and evaluation.
