The invention discloses a cruising ability estimation method based on a navigation system. The cruising ability estimation method comprises the following steps: estimating a theoretical road mileage S0 according to navigation information; estimating extra energy consumption according to the driving path, and calculating the consumed mileage; estimating an energy recovery increasing mileage S6; calculating a theoretical remaining mileage S according to the remaining electric quantity; calculating the endurance mileage Sz required by the vehicle running to the destination according to the formula: Sz = S0 + consumed mileage-S6; and displaying an estimation result. According to the method, various information in the travel path is sensed through navigation, air conditioner and other system data, the vehicle controller pre-estimates the endurance extra consumption value in the travel path, the travel and the remaining endurance are compared and judged, and meanwhile, charging planning suggestions and endurance estimation prompts with higher credibility are given to a user.

    本发明揭示了一种基于导航系统的续航能力估算方法:根据导航信息估算理论道路里程S0;根据行驶路径估算额外的能量消耗,并计算为消耗里程;估算能量回收增加里程S6;根据剩余电量计算理论剩余里程S;计算车辆行驶到目的地所需的续航里程Sz=S0+消耗里程‑S6;显示估算结果。本发明通过导航和空调等系统数据感知行程路径中的多种信息,由车辆控制器预估行程路径中续航额外消耗值,再加上路程与剩余续航对比判断,同时给出用户充电规划建议,以及可信度更高的续航能力估算提示。
