The invention relates to the endurance mileage estimation technology of a new energy vehicle, in particular to an endurance mileage estimation method and device and a computer readable storage medium.The endurance mileage estimation method provided by the invention comprises the following steps: looking up a table according to the model and the state of charge of a power battery and the working condition of a vehicle to obtain empirical estimated value; calculating an average estimated value according to the state of charge and the long-distance average energy consumption of the vehicle; calculating an instantaneous estimated value according to the state of charge and the short-distance instantaneous energy consumption of the vehicle; and performing weighted summation on the empirical estimated value, the average estimated value and the instantaneous estimated value according to the accuracy requirement and the stability requirement for the endurance mileage to obtain the estimated endurance mileage. According to the method and the device, the endurance mileage reading is kept stable while the endurance mileage estimation accuracy is considered, so that the subjective feeling of auser is improved, and the mileage anxiety of the user is reduced.

    本发明涉及新能源汽车的续航里程估算技术,尤其涉及一种续航里程的估算方法及装置,以及一种计算机可读存储介质。本发明提供的上述续航里程的估算方法,包括步骤:根据动力电池的型号及荷电状态以及车辆的工况查表获取经验估算值;根据所述荷电状态及车辆的长距离平均能耗计算平均估算值;根据所述荷电状态及车辆的短距离瞬时能耗计算瞬时估算值;以及根据对续航里程的准确性需求和稳定性需求,对所述经验估算值、所述平均估算值及所述瞬时估算值加权求和以获取估算的续航里程。本发明能够在兼顾续航里程预估准确性的同时,保持续航里程读数的稳定,从而提升用户的主观感受,并降低用户的里程焦虑。
