The invention provides a method for estimating the endurance mileage of an automobile. The method comprises the following steps: dividing a to-be-estimated road section in front of the automobile; acquiring an instantaneous value Pi of motor output driving power and an instantaneous value Qi of battery thermal management system power corresponding to the starting point position of the vehicle in each road section unit, and calculating the corresponding motor output driving power Pi and battery thermal management system power Qi in the road section unit; summing up the motor output driving power Pi and the battery thermal management system power Qi to obtain unit total power Ptotal i corresponding to the road unit; and determining battery consumption energy of the to-be-estimated road section according to the total power Ptotal i. According to the method, the to-be-estimated road section in front of the vehicle is divided, the calculated motor output driving power Pi and the battery heat management system power Qi are added to obtain the unit total power Ptotal i corresponding to the road section unit, the battery consumed energy of the to-be-estimated road section is determined, and therefore the remaining mileage of the vehicle is calculated.
本发明提供了一种汽车续航里程的预估方法,包括以下步骤:对自车前方待预估路段进行路段划分;获取车辆在每个所述路段单元起始点位置对应的电机输出驱动功率的瞬时值Pi和电池热管理系统功率的瞬时值Qi,计算出该所述路段单元内对应的电机输出驱动功率Pi和电池热管理系统功率Qi;将所述电机输出驱动功率Pi和电池热管理系统功率Qi加和得到该路段单元对应的单元总功率P总i;根据总功率P总i确定所述待预估路段的电池消耗能量。本发明通过对自车前方待预估路段进行路段划分,并对计算电机输出驱动功率Pi和电池热管理系统功率Qi加和得到该路段单元对应的单元总功率P总i,进而确定出待估路段的电池消耗能量,从而计算出车辆的剩余里程。
