The invention relates to a torque output control method and device of a motor controller. The method comprises the steps of: acquiring the required output torque of a vehicle and the current output torque of a motor; determining a torque output limit value according to the current output torque; and determining a smaller value between the required output torque and the torque output limit value asan execution output torque. The scheme of the invention is based on the structural characteristics of single-tube parallel IGBT, a strategy suitable for a single-tube parallel IGBT motor controller is formulated, so that the problem of high temperature rise of IGBT under a peak torque can be solved, also the peak current output time of the motor controller can be prolonged, then the actual outputtime of the motor peak torque is prolonged, and the use performance requirement of the whole vehicle is met.

    本申请涉及一种电机控制器的扭矩输出控制方法和装置,所述方法包括:获取车辆的需求输出扭矩和电机的当前输出扭矩;根据当前输出扭矩确定扭矩输出限值;将需求输出扭矩和扭矩输出限值之间的较小值确定为执行输出扭矩。本申请的方案基于单管并联IGBT结构特性,通过制定一种适用于单管并联IGBT电机控制器的策略,不仅可以解决峰值扭矩下IGBT温升高的问题,还能延长电机控制器峰值峰值电流输出时间,进而延长电机峰值扭矩输出实际时间,保证满足整车使用性能要求。
