摘要
文中以用户体验为中心,介绍了用户的操作行为及驾驶习性、交互方式。以智能驾驶辅助系统中的自主换道为例,对换道预警策略模型进行了分析验证,并输出个性化的轨迹曲线。仿真分析表明:激进型驾驶员换道时,个性化匹配的相对横向速度最高且变化幅度最大;适度型驾驶员换道时,个性化匹配的相对速度居中;谨慎型驾驶员换道时,个性化匹配的相对速度稍缓,速度变化幅度相对较低;相对纵向速度变化趋势相近,在转向换道过程中影响不大。通过对用户的个性化分析,使得智能驾驶辅助系统符合用户自身的驾驶习惯,提高驾驶人的操作舒适性。
Focusing on user experience,the user’s operation behavior,driving habits,interaction methods were introduced.Taking the autonomous lane change in intelligent driving assistance system as an example,the lane change early warning strategy model was analyzed and verified,and the personalized trajectory curve was output.The simulation analysis shows that when radical drivers change lanes,the relative lateral speed of personalized matching is the highest and the variation range is the largest.When moderate drivers change lanes,the relative speed of personalized matching is in the middle.When cautious drivers change lanes,the relative speed of personalized matching is slightly slower and the range of speed change is relatively low.The change trend of relative longitudinal speed is similar,and it has little effect in the process of turning and lane changing.Through the personalized analysis of users,the intelligent driving assistance system is in line with users’own driving habits and improves the operation comfort of drivers.
