摘要
对乘用车弯道防侧滑超速报警系统的方案进行了设计,基于多传感器信息融合技术及单回旋线道路模型对车辆前方道路曲率进行估计,结合道路曲率、驾驶员特性及车辆动力学性能等参数计算弯道最大安全车速,引入风险状态预估函数对车辆进入弯道时的安全状态进行判断,进而提前对驾驶员进行报警提示,使得驾驶员能够按照自身的驾驶习惯提前对车辆进行操作,保证车辆通过弯道时的安全性与舒适性。利用试验数据进行离线校验,验证了该系统的有效性。
A scheme of Curve Anti-sideslip Speed Warning System for passenger car was designed.First,based on multiple sensor fusion technique and single-clothoid road model,the road curvature was estimated.And then the maximum safe speed was calculated utilizing the parameters of road curvature,driver behavior and vehicle dynamics.Furthermore,a risk prediction function was introduced to determine the vehicle safety state when vehicle enters into the curve,according to which different levels of warning information was provided to the driver.The warning enables the driver's advanced operation which matches his/her driving behavior to result in safety and comfort when passing through the curve road.Offline tests with field test data verified the validity of the system.
