The invention provides a driver lane changing intention recognition method and system based on a hybrid strategy game. The method comprises the steps that M1, a highway same-direction three-lane scenemodel is established; M2, a vehicle-mounted sensor obtains and analyzes the running states of the vehicle on the current lane and the vehicles on the left and right expected lanes; M3, according to the running state of the vehicle, lane changing conditions are judged, a lane changing scheme based on a game theory mixed strategy is established and executed, then the implicit lane changing intention of the driver is recognized, and meanwhile, the expected benefit of the mixed strategy of the optimal lane changing scheme integrating all conditions is calculated. According to the method, the problem that accidents are likely to happen in the mixed strategy lane changing game process is avoided, the potential safety hazards in the vehicle lane changing process are effectively solved, the driving safety of drivers and vehicles is ensured, and the driving efficiency of driving the vehicles is improved.

    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M1:建立高速路同向三车道场景模型;步骤M2:车载传感器获取并分析当前车道上车辆和左右两条期望车道上车辆运行状态;步骤M3:根据车辆运行状态,判断换道条件,建立并执行基于博弈论混合策略的换道方案,进而识别隐含的驾驶人换道意图,同时计算综合全部情况的最佳换道方案的混合策略期望收益;本发明避免了进行混合策略换道博弈过程中可能产生事故的问题,有效地解决了车辆换道过程中的安全隐患,确保了驾驶人及车辆的驾驶安全,并提高了驾驶车辆的行驶效率。
