The invention provides a control method and device for a dual-motor hybrid power system of a hybrid electric vehicle. The method comprises the steps that when the dual-motor hybrid power system is in a parallel mode, an input shaft request torque requesting for output of an input shaft of a transmission and a first motor request torque requesting for output of a first motor are obtained; if the input shaft request torque is larger than the torque capacity of the clutch, and the difference between the input shaft request torque and the torque capacity of the clutch is smaller than the speed regulation intervention torque capacity of the input shaft, the first motor is controlled to output the sum of the first motor request torque and the intervention negative torque, and the engine is controlled to output the engine torque; the absolute value of the intervention negative torque is less than or equal to the difference between the input shaft request torque and the torque capability of the clutch; the engine torque is positive torque and is equal to the difference between the torque capacity of the clutch and the intervention negative torque; the torque capacity of the clutch is the maximum torque capable of being transmitted by the clutch. The rotating speed can be rapidly increased.

    本申请提供一种混合动力汽车的双电机混动系统的控制方法、装置。方法包括:当双电机混动系统处于并联模式时,获取请求变速器的输入轴输出的输入轴请求扭矩和请求第一电机输出的第一电机请求扭矩;若输入轴请求扭矩大于离合器的扭矩能力,且输入轴请求扭矩和离合器的扭矩能力的差小于输入轴的调速干预扭矩能力,控制第一电机输出第一电机请求扭矩和干预负扭矩之和,控制发动机输出发动机扭矩;干预负扭矩的绝对值小于等于输入轴请求扭矩和离合器的扭矩能力的差;发动机扭矩为正扭矩,等于离合器的扭矩能力和干预负扭矩的差;离合器的扭矩能力为离合器能够传递的最大扭矩。本申请可以较快提升转速。
