The invention provides a position prediction method and system and a vehicle, and the method comprises the steps: predicting an estimated position of a target object at a first moment through a position prediction model according to the driving environment data at the current moment; calculating the actual position of the target object at the first moment according to the driving environment data at the first moment; when the position deviation between the pre-estimated position and the actual position of the target object at the first moment is greater than a preset position deviation, according to the driving environment data at the first moment, the pre-estimated position and the actual position, carrying out online updating on a model parameter value of a position prediction model; and predicting the estimated position of the target object at the second moment through the online updated position prediction model. The invention aims to improve the generalization performance of trajectory prediction in various driving environments.
本发明提供了一种位置预测方法、系统及车辆,所述方法包括:根据当前时刻的驾驶环境数据,通过位置预测模型预测目标对象在第一时刻的预估位置;根据第一时刻的驾驶环境数据,计算目标对象在第一时刻的实际位置;在目标对象在第一时刻的预估位置和实际位置之间的位置偏差大于预设位置偏差时,根据第一时刻的驾驶环境数据、预估位置和实际位置,对位置预测模型的模型参数值进行在线更新;通过在线更新后的位置预测模型,预测所述目标对象在第二时刻的预估位置。旨在提高轨迹预测在多种驾驶环境下的泛化性能。
