The invention discloses a method and system for determining the remaining capacity of a vehicle in transit battery, and the method comprises the steps: obtaining the information of a road where a vehicle is located and the information of a current position under the condition that the vehicle is determined to be running; matching the road information in a preset path database to obtain first path information; acquiring a driving habit set corresponding to the first path information, wherein the driving habit set comprises an accelerator gear set, a brake force set and a lighting duration set; performing feature selection on the driving habit set by using a feature selection algorithm to obtain a first correlation coefficient corresponding to the accelerator gear set, a second correlation coefficient corresponding to the brake force set and a third correlation coefficient corresponding to the lighting duration set; establishing an electric quantity estimation model according to the first correlation coefficient, the second correlation coefficient and the third correlation coefficient; and inputting the current position information into the electric quantity pre-estimation model to obtain the current pre-estimated residual electric quantity. And the accuracy of determining the remaining capacity of the battery when the vehicle is in transit is improved.

    一种车辆在途电池剩余电量确定的方法及系统,在该方法中,在确定车辆正在行驶的情况下,获取车辆所在的道路信息及当前位置信息;在预设路径数据库中匹配道路信息,得到第一路径信息;获取第一路径信息对应的驾驶习惯集,驾驶习惯集包括油门档位集、刹车力度集及灯光照明时长集;使用特征选择算法对驾驶习惯集进行特征选择,得到油门档位集对应的第一相关系数、刹车力度集对应的第二相关系数及灯光照明时长集对应的第三相关系数;以第一相关系数、第二相关系数及第三相关系数建立电量预估模型;将当前位置信息输入电量预估模型,得到当前预估剩余电量。提高了对车辆在途时电池的剩余电量确定的准确度。
