The invention discloses a remaining mileage estimation method and device, relates to the technical field of electric vehicles, and mainly aims to ensure the accuracy of endurance mileage estimation so as to improve the driving experience. According to the main technical scheme, multiple pieces of real-time mileage power consumption of a vehicle under multiple time scales are obtained, the multiple time scales are determined according to the same time node, and one piece of real-time mileage power consumption corresponds to one time scale; the multiple real-time mileage power consumptions are input into a trained preset time sequence model, predicted mileage power consumption is obtained, and the preset time sequence model is used for predicting mileage power consumption corresponding to a set remaining mileage; and calculating the actual remaining mileage of the vehicle based on the predicted mileage power consumption and the current remaining electric quantity. The method is used for estimating the remaining endurance mileage of the vehicle.
本申请公开了一种剩余里程估算方法及装置,涉及电动汽车技术领域,主要目的是保证续航里程估算的准确性,以提升驾驶体验。本申请主要的技术方案为:获取车辆在多个时间尺度下的多个实时里程电耗,其中,多个时间尺度是按照同一时间结点确定的,且一个所述实时里程电耗对应一个所述时间尺度;将多个所述实时里程电耗输入训练好的预置时序模型中,得到预测里程电耗,其中,所述预置时序模型为用于预测既定剩余里程所对应的里程电耗;基于所述预测里程电耗和当前剩余电量计算所述车辆的实际剩余里程。本申请用于车辆剩余续航里程的估算。
