The invention discloses a method and a device for predicting the endurance mileage of a vehicle. The method comprises the following steps: acquiring own vehicle data and environment data of the vehicle on a current road section; obtaining a first remaining endurance mileage of the vehicle on the current road section based on the vehicle driving historical data and the current position; inputting the environment temperature into a preset battery discharge model to obtain an optimization coefficient reflecting the influence of the environment temperature on the battery discharge capability; calculating the actual output power of the battery according to the optimization coefficient and the battery data; acquiring a second remaining endurance mileage of the vehicle on the current road section; and predicting the endurance mileage of the vehicle according to the weight influence of the first residual endurance mileage and the second residual endurance mileage. According to the method and the device for predicting the endurance mileage of the vehicle provided by the embodiment of the invention, the influence of the historical data and the environment temperature on the endurance capability of the vehicle is comprehensively considered by performing double analysis on the historical data and the discharge capability of the battery, so that the accuracy of the endurance mileage of the vehicle is improved, and the intelligent process of the vehicle is promoted.

    本发明公开了一种车辆续航里程的预测方法和装置,包括获取车辆在当前路段上的自车数据和环境数据;基于车辆行驶历史数据和当前位置获取车辆在当前路段上的第一剩余续航里程;将环境温度输入预置的电池放电模型中得到反映环境温度对电池放电能力影响的优化系数;根据优化系数和电池数据计算电池的实际输出功率;获取车辆在当前路段上的第二剩余续航里程;根据第一剩余续航里程和第二剩余续航里程的权重影响进行车辆的续航里程预测。本发明实施例提供的车辆续航里程的预测方法和装置,通过对历史数据和电池放电能力进行双重分析,综合考虑了历史数据和环境温度对车辆续航能力的影响,从而提高了车辆续航里程的准确度,推进了车辆的智能化进程。
