The invention belongs to the technical field of automobiles, and discloses an automobile power system control method, a device and equipment and a storage medium. The method comprises the following steps: acquiring available power of a battery system corresponding to a current automobile; acquiring a current road condition, a current motor speed and a speed change gradient; determining motor torque according to the current road condition, the current motor speed and the speed change gradient; determining a target motor torque according to the available power of the battery system and the motortorque; and controlling a motor in the automobile power system to output the target motor torque. Through the mode, the available power of the battery system and the motor torque are obtained, the torque of the motor is dynamically controlled according to the available power of the battery system and the motor torque, the output capacity of a dual-power system is reasonably controlled, and the problems that the current power system capacity cannot be fully utilized, and the whole vehicle dynamic property and drivability are influenced, and the user experience is poor are solved.

    本发明属于汽车技术领域,公开了一种汽车动力系统控制方法、装置、设备及存储介质。该方法包括:获取当前汽车对应的电池系统可用功率;获取当前道路工况、当前电机转速以及转速变化梯度;根据当前道路工况、当前电机转速以及转速变化梯度确定电机扭矩;根据电池系统可用功率和电机扭矩确定目标电机扭矩;控制汽车动力系统中的电机输出目标电机扭矩。通过上述方式,获取电池系统可用功率及电机扭矩,根据电池系统可用功率及电机扭矩动态控制电机的扭矩大小,合理控制双动力系统输出能力,解决了当前动力系统能力无法充分利用,影响整车动力性以及驾驶性,造成用户体验较差的技术问题。
