解放J6商用车前撞告警系统开发

针对商用车质量大且制动系统响应时间长,因此易发生碰撞造成严重死伤的问题,开发了基于商用车特点的前撞告警(FCW)系统。分别对该商用车FCW系统进行了客观验证和主观评价。结果表明,在设定场景下,除20km/h以下工况,该FCW系统告警时机满足设计值和相关法规要求;设定场景FCW系统准确告警率>80%,误报率<5%,满足正常使用要求;实际道路行驶过程中,系统运行良好,无失效情况;主观评价结果为总体满意。

Development of Commercial Vehicle's FCW for JieFang J6

In response to the high mass and long response time of commercial vehicles,which will easily lead to collision and servere casualties,forward collision warning(FCW) system is developed based on the commercial vehicle’s characteristics.Objective validation and subjective evaluation have been performed to the FCW System of commercial vehicles.Results show that under given conditions except for below 20km/h,FCW System warning time could meet the design value and related regulation requirements.FCW System warning accuracy rate is more than 80% and the error rate is less than 5%,which could meet the normal operation requirements.FCWS operates well on the real road test,and no failure occurs.The subjective evaluation results are satisfactory as a whole.
