摘要:

针对纯电动汽车传统自适应巡航系统存在的驾驶风格适配性不足问题,提出了一种基于驾驶行为特征的人性化起停控制策略。首先,对真实驾驶员的起停数据进行分析与特征提取,并利用主成分分析与K-means++算法构建驾驶风格分类模型;其次,设计双层控制架构,实现类人的驱动、制动切换控制逻辑;再次,基于贝叶斯线性回归与最大熵逆优化方法设计人性化因子;最后,通过仿真测试分析,验证了所提方法与真实驾驶员操控行为的一致性。

Abstract:

Addressing the issue of insufficient adaptation to driving styles in the traditional adaptive cruise system of pure electric vehicles, a humanized stop-and-go control strategy based on driving behavior characteristics was proposed. Firstly, real driver stop-and-go data were analyzed and features extracted, and construction of a driving style classification model using principal component analysis and the K-Means++ algorithm. Secondly, a two-layer control architecture was designed to implement the human-like control logic for switching between driving and braking. Thirdly, a humanization factor was designed based on Bayesian linear regression and maximum entropy inverse optimization methods. Finally, the consistency between the proposed method and real drivers' control behaviors was validated through simulation tests aralysis.

Key words: automotive engineering, pure electric vehicles, adaptive cruise control, stop-and-go control, humanized decision-making control
