The invention provides a motor drive control method of a hybrid electric vehicle. A total torque of a first motor directly connected to the engine and a second motor directly connected to an input of the transmission is determined based on the required torque and the torque distributed to the engine. One of a first combined efficiency map and a second combined efficiency map, in which conversion references of a motor driving mode are set differently, is selectively applied to an efficiency map of a second motor based on information on the motor driving mode applied to the second motor. A total torque is distributed to each of the first motor and the second motor based on an efficiency map of the first motor and an efficiency map of the second motor.

    本公开提出一种混合动力电动车辆的马达驱动控制方法。基于所需扭矩和分配给发动机的扭矩,确定直接连接到发动机的第一马达和直接连接到变速器的输入端的第二马达的总扭矩。基于关于应用于第二马达的马达驱动模式的信息,将不同地设置马达驱动模式的转换基准的第一合成效率图和第二合成效率图中的一个选择性地应用于第二马达的效率图。基于第一马达的效率图和第二马达的效率图,将总扭矩分配给第一马达和第二马达中的每一个。
