The invention provides a driver lane changing intention recognition method and system based on a hybrid strategy game. The method comprises the steps of 1, establishing an urban road one-way three-lane scene; 2, acquiring the running states of vehicles on the current lane, a first expected lane and a second expected lane, and judging whether the running states are special conditions or not; 3, establishing a lane changing vehicle pure strategy set according to judgment; 4, selecting lagging vehicles lagging behind a lane changing vehicle in the target lane, and establishing a lagging vehicle pure strategy set; and 5, according to the lane changing vehicle pure strategy set, the lag vehicle pure strategy set and the hybrid game strategy, judging the lane changing benefit and the driving style of the driver, and further judging the lane changing intention of the driver. On the basis of an urban road scene, possible road conditions in the urban road scene are analyzed and discussed, the problem of vehicle lane changing in a special scene is solved, the driving safety and legality are guaranteed, and the invention is close to life.
本发明提供了一种基于混合策略博弈的驾驶人换道意图识别方法及系统,包括:步骤1:建立城市道路单向三车道场景;步骤2:获取当前车道和第一、第二期望车道上的车辆的运行状态,并判断是否为特殊情况;步骤3:根据判断建立换道车辆纯策略集合;步骤4:选定目标车道中的滞后于换道车辆的滞后车辆,建立滞后车辆纯策略集合;步骤5:根据换道车辆纯策略集合、滞后车辆纯策略集合和混合博弈策略,判断换道的收益以及驾驶人的驾驶风格,进而判断驾驶人的换道意图。本发明以城市道路场景为基础,对城市道路场景下可能出现的路况进行了分析讨论,解决了特殊场景下的车辆换道问题,保证了行驶的安全性和合法性,且贴近生活。
