The invention provides an automobile endurance mileage prediction method and device. The method comprises the following steps: firstly, obtaining driving historical data of a target vehicle and a pre-constructed gray prediction model; constructing a probability density distribution model of the unit energy consumption mileage according to the driving historical data; in the practical application, the current vehicle data of a target vehicle is acquired; then performing prediction according to a probability density distribution model and current vehicle data to obtain a first endurance prediction value; performing prediction according to the gray prediction model and the current vehicle data to obtain a second endurance prediction value; and finally, calculating a final endurance mileage prediction result according to a pre-calculated weight coefficient, the first endurance prediction value and the second endurance prediction value. Therefore, the method can accurately predict the residual endurance mileage, gives consideration to the stability and sensitivity of prediction, and provides accurate and reliable residual endurance mileage information for a user.

    本申请提供一种汽车续航里程预测方法及装置,该方法包括:先获取目标车辆的行驶历史数据和预先构建的灰色预测模型;再根据行驶历史数据构建单位能耗行驶里程的概率密度分布模型;在实际应用中,先获取目标车辆的当前车辆数据;然后根据概率密度分布模型和当前车辆数据进行预测,得到第一续航预测值;再根据灰色预测模型和当前车辆数据进行预测,得到第二续航预测值;最后,根据预先计算的权重系数、第一续航预测值和第二续航预测值计算最终续航里程预测结果。可见,该方法能够准确地预测剩余续航里程,兼顾了预测的稳定性和灵敏性,为用户提供了精确可靠的剩余续航里程信息。
