【摘要】：驾驶倾向性是汽车行驶中驾驶员情感偏好等特征的动态测度,易随环境的改变而变化,并影响驾驶员意识和汽车操控行为;另一方面,其类型和转移概率又同时受到后者的作用与影响.准确揭示动态环境下驾驶倾向性转移概率,对实现汽车自动驾驶和辅助驾驶系统具有重要意义.本文以三车道为例,从环境变化,特别是从刻画交通态势复杂性的车辆编组关系演化角度出发,设计三车道条件下的驾驶实验,采集不同行驶环境下驾驶员倾向性并进行统计分析,揭示环境嬗变情况下,汽车驾驶倾向性转移概率.验证结果表明,利用倾向性转移概率对汽车驾驶员倾向性进行预测的结果与实时辨识结果相吻合,平均准确率达80%以上.
[Abstract]:Driving tendency is a dynamic measure of drivers' emotional preference and other characteristics in vehicle driving. It is easy to change with the change of environment, and affects driver's consciousness and vehicle control behavior; on the other hand, Its type and transition probability are also affected by the latter. It is of great significance to accurately reveal the probability of driving tendency transfer in dynamic environment for the realization of automatic driving and auxiliary driving system. Taking the three-lane as an example, this paper designs the driving experiment under the three-lane condition from the angle of environment change, especially from the angle of the evolution of the vehicle marshalling relationship, which depicts the complexity of traffic situation. The tendency of drivers in different driving environments was collected and analyzed statistically to reveal the probability of vehicle driving tendency transfer under the circumstance of environmental change. The results of verification show that the prediction results of the tendency of vehicle drivers by using the propensity transfer probability are in agreement with the real-time identification results, and the average accuracy is over 80%.
