The advanced driver assistance system (ADAS) in longitudinal vehicle dynamics which included full speed adaptive cruise control (FS ACC), automatic emergency braking (AEB) and forward collision warning (FCW), was developed to carry on the effective exploration and for the technical accumulation for the system mass production on the developing platform of the integrated active safety system Dongfeng Fengshen AX7. By using the extended electrical power steering, lane centering assist (LC), lane keeping assist (LKA) and lane departure warning (LDW) were applied on the developing platform; more than the integrated chassis control, integrated active driving adjustment, active braking and active steering were firstly proposed and employed. FS ACC with steering intervention has been realized on highway. All of the related components, subsystems and systems on the platform were realized to be produced in mass. And the on-line test was also carried out on high way. The results shows that a low-cost technical approach for semi-automated driving vehicle on the highway is preliminarly proposed.The system is proved to be practicable.%为了对东风风神AX7集成主动安全系统的量产进行有效的探索和技术积累,在此系统开发平台的基础上,开发了在纵向动力学控制上的高级驾驶辅助系统(ADAS),包括全速自适应巡航系统(FS ACC)、自动紧急制动辅助系统(AEB)和前向碰撞预警系统(FCW);通过扩展电动助力转向系统实现主动转向功能,开发了车道中线保持系统(LC)、车道保持辅助系统(LKA)和车道偏离预警系统(LDW).实现带有转向干预的全速域高速公路半自动驾驶系统.对车辆行驶采取了综合控制,初步实现集成主动动力调节、主动制动和主动转向的集成底盘控制;所有的零部件、总成和系统都已经实现量产,基于城市高架及高速公路也进行了实车测试.结果表明:该系统方案能解决低成本车辆实现高速公路半自动驾驶的技术难题,且具有良好的可行性.
