The embodiment of the invention provides a virtual lane generation method, and the method comprises the steps: obtaining the feature data of two lanes, and enabling the two lanes to have a connection relation; a thermodynamic diagram prediction model is obtained, the thermodynamic diagram prediction model is a trained first machine learning model, and the thermodynamic diagram prediction model is obtained by training the first machine learning model based on historical driving data; on the basis of the feature data, estimated thermodynamic diagrams corresponding to the two lanes are obtained through a thermodynamic diagram prediction model, and the estimated thermodynamic diagrams represent estimated vehicle track distribution passing between the two lanes; and determining a virtual lane between the two lanes based on the estimated thermodynamic diagram, the virtual lane for guiding the vehicle from one of the two lanes to the other.

    本说明书实施例提供一种虚拟车道生成的方法,该方法包括:获取两个车道的特征数据,两个车道之间具有连接关系;获取热力图预测模型,其中,热力图预测模型为训练后的第一机器学习模型,热力图预测模型基于历史驾驶数据训练第一机器学习模型获得;基于特征数据,通过热力图预测模型获取两个车道对应的估计热力图,估计热力图表示两个车道之间通行的估计车辆轨迹分布;以及基于估计热力图,确定两个车道之间的虚拟车道,虚拟车道用于引导车辆从两个车道中的一个车道到达另一个车道。
