The invention discloses an endurance mileage estimation method which comprises the following steps: determining a low-temperature influence factor influencing the endurance mileage of a vehicle according to the power consumption difference of the vehicle running under a low-temperature condition and a normal-temperature condition, utilizing the low-temperature influence factors to correct an endurance mileage normal-temperature calculation model of the vehicle to obtain an endurance mileage low-temperature calculation model of the vehicle; the method comprises the following steps: driving and braking a vehicle according to a speed-time curve required by a standard driving working condition single cycle period under a normal temperature condition, sampling mechanical data of the vehicle in real time, and inputting the mechanical data into an endurance mileage low-temperature calculation model of the vehicle for calculation, and the endurance mileage of the vehicle under the standard driving working condition and the low-temperature condition is determined by combining the power consumption of the air conditioner under the low-temperature condition. According to the scheme, the endurance mileage of the vehicle at the low temperature can be quickly and accurately estimated.

    本文公开一种续航里程估算方法,包括:根据车辆在低温条件和常温条件下行驶的耗电差异确定影响所述车辆的续航里程的低温影响因素,利用所述低温影响因素修正所述车辆的续航里程常温计算模型得到所述车辆的续航里程低温计算模型;在常温条件下按照标准行驶工况单循环周期要求的速度时间曲线对车辆进行驱动和制动,实时采样车辆的力学数据,将所述力学数据输入所述车辆的续航里程低温计算模型进行计算,结合空调在低温条件下的耗电量确定所述车辆在标准行驶工况低温条件下的续航里程。本文的方案能够快速、准确地估算车辆在低温下的续航里程。
