The embodiment of the invention provides a prediction model training method and device. The method comprises the following steps: acquiring a first speed curve and a first relative distance curve corresponding to the driving process of a vehicle; according to the first speed curve, at least one parking event in the driving process is determined, and a first parking position corresponding to the parking event is obtained. And for any parking event, marking the real parking type of the parking event according to the first speed curve and the parking duration threshold. And processing the first speed curve, the first relative distance curve and the first parking position according to a prediction model to obtain a predicted parking type output by the prediction model. And according to the real parking type and the predicted parking type, updating model parameters of the prediction model. By training the prediction model capable of outputting the accurate predicted parking type, the internal combustion engine is shut down based on the start-stop system only when the predicted parking type is effective, and the problem of power consumption caused by unnecessary shut-down of the internal combustion engine is avoided.

    本申请实施例提供一种预测模型训练方法及装置,该方法包括:获取车辆的行驶过程所对应的第一速度曲线以及第一相对距离曲线。根据第一速度曲线,确定行驶过程中的至少一次停车事件,并获取停车事件所对应的第一停车位置。针对任一个停车事件,根据第一速度曲线以及停车时长阈值,标注停车事件的真实停车类型。根据预测模型对第一速度曲线、第一相对距离曲线以及第一停车位置进行处理,得到预测模型输出的预测停车类型。根据真实停车类型和预测停车类型,对预测模型的模型参数进行更新。通过训练能够输出准确的预测停车类型的预测模型,以在预测停车类型为有效的时候,才基于启停系统关闭内燃机,避免内燃机不必要的关闭所导致的功耗问题。
