The invention discloses an EV type endurance mileage calculation method and system and an automobile, and belongs to the technical field of EV energy management, and the method comprises the steps: obtaining vehicle navigation information and local energy consumption information, and combining the vehicle navigation information to fit driving condition vehicle speed change to obtain fitting driving condition vehicle speed information; the vehicle speed change is predicted based on the actual driving route and the road condition, so that the actual driving working condition is more accurately simulated, the vehicle driving energy consumption from the departure place to the destination can be more accurately calculated according to the more accurate fitting driving working condition vehicle speed information in combination with a power system model and temperature compensation correction, and then more accurate endurance mileage prediction is obtained. Meanwhile, due to the fact that the method is based on navigation information obtained in real time, prediction of the endurance mileage can be dynamically adjusted so as to adapt to various changes possibly occurring in the driving process, and real-time updating of local energy consumption information further enhances the real-time performance and the dynamic performance of endurance mileage calculation; and the accuracy and scientificity of the prediction method are further improved.

    一种EV车型续航里程计算方法、系统及汽车,属于EV汽车能量管理技术领域,通过获取车辆导航信息和本地能耗信息,结合车辆导航信息拟合行驶工况车速变化得到拟合行驶工况车速信息;基于实际行驶路线和路况来预测车速变化,从而更准确地模拟实际行驶工况,根据更准确的拟合行驶工况车速信息,结合动力系统模型和温度补偿修正,可以更精确地计算出发地到目的地的车辆行驶能耗,进而得到更准确的续航里程预测;同时由于该方法基于实时获取的导航信息,因此能够动态地调整续航里程的预测,以适应行驶过程中可能出现的各种变化,本地能耗信息的实时更新也进一步增强了续航里程计算的实时性和动态性;进一步地提高了本预测方法的准确性和科学性。
