车辆前向防碰撞主动预警系统设计
|
摘要
交通运输部《JT/T 1094-2016》标准规定:自2018年4月1日起,新生产的9米以上营运客车需安装前向防碰撞预警系统(forward collision warning system,FCWS)。研究设计了一种车辆前向防碰撞主动预警系统,系统通过毫米波雷达传感器进行车辆之间相对距离及相对速度监测,通过卡尔曼滤波算法对前向有效目标车辆进行优先监测,通过两级预警策略算法进行预警,在车辆存在潜在的碰撞危险时,通过视觉、听觉、触觉三种方式发出报警信息。
According to the JT/T 1094-2016 standard formulated by the Ministry of Transport,it is required to install a forward collision warning system( FCWS) for newly-produced cars which are over 9 meters since April 1,2018. A FCWS based on millimeter-wave radars was developed. The system detects the distance and relative speed information between the self-vehicle and the forward objects by millimeter-wave radars,and Kalman filter algorithm is used to select the forward vehicle,and two-stage warning strategy algorithm is used to warn the driver.If there is a potential collision risk between the self-vehicle and the forward objects,the FCWS will send out alarm information by three means of vision,hearing,and touching.
