The invention discloses an equivalent factor acquisition method, which is characterized in that in order to acquire an equivalent factor of a current period, the endurance time corresponding to a vehicle at the current moment is acquired, and the endurance time refers to the possible driving duration under the condition that the vehicle only uses a motor to provide power. Meanwhile, the vehicle speed of the vehicle and the electric quantity difference value between the remaining electric quantity of the battery at the current moment and the target remaining electric quantity are obtained; and updating the equivalent factor of the previous updating period according to the vehicle speed, the endurance time and the electric quantity difference value to obtain the equivalent factor of the current updating period. Namely, when the equivalent factors are updated, the vehicle driving state information such as the endurance time, the vehicle speed and the remaining electric quantity is considered, so that the updated equivalent factors can better fit the current working condition of the vehicle, and a more accurate equivalent coefficient is provided for subsequent energy management.
本申请公开了一种等效因子获取方法,为获取当前周期的等效因子,将获取当前时刻车辆对应的续航时间,该续航时间是指车辆在只利用电机提供动力的情况下,可能行驶的时长。同时,获取车辆的车速以及当前时刻电池的剩余电量与目标剩余电量之间的电量差值。进而根据车速、续航时间以及电量差值对上一更新周期的等效因子进行更新,获得当前更新周期的等效因子。即,本申请在对等效因子进行更新时,考虑续航时间、车速以及剩余电量等车辆行驶状态信息,从而使得更新后的等效因子能够更加贴合车辆的当前工况,为后续的能量管理提供更加精准的等效系数。
