| 摘 要： | 汽车前碰撞预警系统(Forward Collision Warning System,FCWS)可以显著降低追尾事故发生风险,为了加强测试法规的认知,本文对比分析了JT/T 883-2014、GB/T 33577-2017以及韩国KC TEST关于FCWS的测试标准及理论依据,解析了测试法规涉及的测试参数确定的原因。分析结果表明:各法规的测试方法类似,但指标有所差异;JT/T 883-2014关于碰撞时间(Time-to-Collision)的设置更为保守;GB/T 33577-2017以及韩国KC TEST关于TTC的设置类似,但KC TEST的标准从使用体验上更为严格合理;此外,当两车存在相对加速度时,考虑相对加速度变化的TTC计算是非常有必要的。

| Abstract: | It is widely known that forward collision warning system(FCWS)can be applied in the vehicle to reduce rear-end collision risk.In order to strengthen knowledge of testing regulations of FCWS,regulations including JT/T 883-2014,GB/T 33577-2017 and Korean KC test are analyzed.In detail,parameters involved in the testing regulations are explained.It is illustrated that testing measure of different regulations are similar with some discrepancies of FCWS testing criteria;TTC(Time-to-Collision)setting of JT/T 883-2014 is more conservative than GB/T 33577 and KC TEST;TTC setting of GB/T 33577 and KC TEST are similar,but there is an upper limit for KC TEST,which is more reasonable than GB/T 33577 for the user experience.In addition,it is important to consider relative acceleration for TTC calculation. |
