The invention provides a method for determining a driving style coefficient based on particle optimization, and the method comprises the steps: carrying out the particle optimization of a first driving style coefficient corresponding to each current moment in a current time period, and obtaining a second driving style coefficient in the current time period; correcting the second driving style coefficient based on a satisfaction evaluation strategy; in this way, the driving style coefficient table is determined after principal component analysis is performed on historical driving parameter samples under different driving styles under various typical working conditions in advance, so that the first driving style coefficient can be determined according to the driving style coefficient table and the driving parameters at the current moment; the driving style belongs to the driving behavior essential characteristics of the driver and reflects the long-term typical driving behavior of the driver, so that a second driving style coefficient in a certain time period is found through a particle optimization algorithm; and the satisfaction evaluation of the driver is incorporated, the second driving style coefficient is corrected, and the accuracy of the driving style coefficient representing the driving behavior of the driver is improved.
本发明提供一种基于粒子寻优确定驾驶风格系数的方法,包括:确当前时段内的各当前时刻对应的第一驾驶风格系数进行粒子寻优,得到当前时段内的第二驾驶风格系数;基于满意度评价策略对第二驾驶风格系数进行修正;如此,由于驾驶风格系数表是预先根据各典型工况下的不同驾驶风格下的历史驾驶参数样本进行主成分分析后确定的,因此可根据驾驶风格系数表和当前时刻的驾驶参数确定出第一驾驶风格系数;而驾驶风格属于驾驶员的驾驶行为本质特征,反映的是驾驶员长期的典型驾驶行为,因此本发明还过粒子寻优算法,找到某一时间段内的第二驾驶风格系数;再纳入驾驶员的满意度评价,修正第二驾驶风格系数,提高驾驶风格系数表征驾驶员的驾驶行为的准确性。
