The invention provides a motor torque control method for a hybrid vehicle. The method comprises the steps that first state information of the hybrid vehicle is obtained; the working states of the hybrid vehicle are determined according to the first state information, wherein the working states comprise the first working state, the second working state and the third working state; the motor torque is adjusted according to the working state, if the working state is the first working state, the motor torque is adjusted to be the first torque, if the working state is the second working state, the motor torque is adjusted to be the second torque, and if the working state is the third working state, the motor torque is adjusted to be the third torque. The problem that impact of a motor gear and a chain is generated or rough noise is generated due to the fact that the motor torque cannot be correspondingly and accurately adjusted when a hybrid vehicle is in different working states in the prior art is solved, and accurate meshing of the gear for outputting the torque of the motor and the chain for transmitting the torque in the different working states is improved. And the driving quality of the hybrid vehicle is also improved.

    本发明提供一种混动车辆的电机扭矩控制方法,该方法包括:获取混动车辆的第一状态信息;根据第一状态信息确定混动车辆的工作状态,工作状态包括第一工作状态、第二工作状态和第三工作状态;根据工作状态调整电机扭矩,其中,若工作状态为第一工作状态,则调整电机扭矩为第一扭矩,若工作状态为第二工作状态,则调整电机扭矩为第二扭矩,若工作状态为第三工作状态,则调整电机扭矩为第三扭矩。解决了现有技术中混动车辆在不同工作状态下由于电机扭矩不能对应的准确调整,产生电机齿轮和链条的冲击或者发出粗糙噪音等问题,提高了电机输出扭矩的齿轮与用于传递扭矩的链条在不同工作状态下的准确啮合,也提高了混动车辆的驾驶品质。
