摘　　要：对于自动驾驶汽车来说,在城市交叉路口安全行驶是一项相当具有挑战性的任务,复杂的道路几何形状和迎面而来车辆的高度机动性可能会导致潜在的碰撞高风险。车用无线通信技术(Vehcile to Everything,V2X)通信可以克服车载传感器的局限性。在交叉路口碰撞预警V2X量产软件的开发过程中,功能测试是非常重要的环节。本文介绍了如何使用RoadRunner场景工具创建一个由带交通灯的十字路口组成的复杂城市场景,将高清(HD)地图转换为符合V2X标准的地图消息,并创建了Simulink模型,与RoadRunner场景进行协同仿真,以验证ICW算法的性能。该模型可用于SIL和HIL系统,以验证量产域控制器中的V2X软件功能。For autonomous vehicles,driving safely at urban intersections is a very challenging task,the complex road geometry and the high mobility of oncoming vehicles may lead to a potential high risk of collision.Vehile-to-Everything(V2X)communication can overcome the limitations of vehicle sensors.In the development process of V2X mass production software,intersection collision warning,function test is a very important link.This article describes how to use the Roadrunner scene tool to create a complex urban scene composed of intersections with traffic lights.Then,we convert high definition(HD)maps into map messages that conform to the V2X standard.We created a Simulink model to co simulate with the Roadrunner scenario to verify the performance of the ICW algorithm.The model can be used in SIL and HIL systems to verify the V2X software function in the mass production controller domain.
