The invention provides an intelligent automobile personification lane changing method and system based on data driving. The method comprises the steps that information of a left lane, a right lane and vehicles in front of the lane is collected; acquiring information of a lane changing starting moment of the vehicle; the collected information serves as an input variable, the rotation angle of a steering wheel serves as an output variable, and a training set of a vehicle lane changing model is constructed; a vehicle steering wheel angle curve model is established based on data driving; sending a vehicle lane changing decision instruction; lane changing is carried out based on a vehicle steering wheel angle curve model established through data driving; and the lane changing action of the vehicle is completed. A lane changing process in real driving of a driver is taken as a training set of a model, the model is constructed by a small amount of data, the change of a steering wheel rotation angle in the lane changing process of the driver is reproduced, and a personification lane changing process is realized.

    本公开提供了一种基于数据驱动的智能汽车拟人化换道方法及系统,包括采集左右车道与本车道前车的信息;获取本车换道起始时刻的信息;将采集的信息作为输入变量,方向盘的转动角度作为输出变量,构建车辆换道模型的训练集;基于数据驱动建立本车方向盘转角曲线模型;发出车辆换道决策指令;基于数据驱动建立的本车方向盘转角曲线模型进行变道;完成本车换道动作。基于驾驶员的真实驾驶中的换道过程作为模型的训练集,以少量数据实现模型的构建,复现驾驶员在换道过程中方向盘转动角度的变换,实现拟人化换道过程。
