The invention provides an automobile motor torque output control method, device and equipment and a storage medium. The method comprises the following steps: acquiring first time discharge power and second time discharge power; obtaining a first motor torque corresponding to the first time discharge power and a second motor torque corresponding to the second time discharge power; when the first time discharge power is not smaller than the preset power value, motor torque output is controlled according to the first motor torque and the second motor torque; and when the first-time discharge power is smaller than the preset power value, motor torque output is controlled according to the first-time discharge power. According to the magnitude relation between the first-time discharge power and the preset power value, different control strategies are adopted, the torque maximum value of the low-rotating-speed section is limited in advance, and the torque in the starting stage is made to change smoothly when the rotating speed is decreased.

    本发明提供一种汽车电机扭矩输出控制方法、装置、设备及存储介质,该方法中获取第一时间放电功率和第二时间放电功率;再获取第一时间放电功率对应第一电机扭矩,第二时间放电功率对应的第二电机扭矩;当第一时间放电功率不小于预设功率值时,根据第一电机扭矩和第二电机扭矩控制电机扭矩输出;当第一时间放电功率小于预设功率值时,根据第一时间放电功率控制电机扭矩输出。本发明根据第一时间放电功率与预设功率值之间的大小关系,采用不同的控制策略,提前限制低转速段的扭矩最大值,使起步阶段的扭矩随转速下降时变化平顺。
