The invention provides a new energy automobile energy control method and system and a readable storage medium, and the method comprises the steps: obtaining the rotating speed of a motor, the automobile speed and the opening degree of an accelerator pedal, and obtaining the current rotating speed acceleration of the motor according to the rotating speed of the motor; acquiring a motor rotating speed of a next period according to the current motor rotating speed acceleration, acquiring predicted driving power according to the motor rotating speed of the next period, and acquiring actual driving power according to the motor rotating speed of the target vehicle in the current period; obtaining the current whole vehicle acceleration of the target vehicle, and obtaining a predicted energy control credible factor based on a first preset rule; selecting matched power as first driving power according to the predicted energy control credible factor; and the maximum allowable driving power of the target vehicle is obtained, and energy management is conducted according to the first driving power and the maximum allowable driving power. According to the invention, the problem that the driving safety and the driving smoothness are poor due to the fact that the battery is easily overcharged and overdischarged in the energy management of the automobile can be solved.

    本发明提出一种新能源汽车能量控制方法、系统及可读存储介质,该方法包括:获取电机转速、车速以及油门踏板开度,并根据电机转速获取当前电机转速加速度;根据当前电机转速加速度获取下一周期的电机转速,根据下一周期的电机转速获取预测驱动功率,并根据目标车辆在当前周期的电机转速获取实际驱动功率;获取目标车辆的当前整车加速度,并基于第一预设规则获取预测能量控制可信因子;根据预测能量控制可信因子选择匹配的功率作为第一驱动功率;获取目标车辆的最大允许驱动功率,根据第一驱动功率和最大允许驱动功率进行能量管理。本发明能够解决汽车的能源管理因容易出现电池过充过放的情况而导致驾驶安全性和行驶平顺性较差的问题。
