The invention relates to the technical field of automobile power transmission, in particular to a double-motor gear shifting method and a control system. The double-motor gear shifting method comprises the following steps that based on a target gear, one of two motors serves as a gear shifting motor, and the other motor serves as a power maintaining motor; a gear shifting step is executed on the gear shifting motor, and the gear shifting step comprises the steps that the torque of the gear shifting motor is reset, and the torque of a power maintaining motor is adjusted to a first target torque; a gear shifting mechanism of the gear shifting motor is shifted to a neutral gear, and then the gear shifting motor is adjusted to the target rotating speed; a gear shifting mechanism of a gear shifting motor is shifted to the target gear; the power maintaining motor serves as a gear shifting motor, and the gear shifting step is executed; and the gear shifting motor is adjusted to the second target torque, and the power maintaining motor is adjusted to the third target torque. The embodiment of the invention provides a dual-motor gear shifting method and a control system to solve the problem that in the dual-motor gear shifting process in the prior art, two motors drive at the same time, and the process is tedious and complex.

    本申请涉及汽车动力传输技术领域,特别涉及一种双电机换挡方法及控制系统。双电机换挡方法包括以下步骤:基于目标档位,将两个电机中的一个作为换挡电机,另一个作为动力维持电机;对所述换挡电机执行换挡步骤,所述换挡步骤包括:将换挡电机的扭矩清零,并将动力维持电机的扭矩调整至第一目标扭矩;将换挡电机的换挡机构摘挡至空挡,再将换挡电机调整至目标转速;将换挡电机的换挡机构挂至所述目标档位;再将动力维持电机作为换挡电机,执行换挡步骤;调整换挡电机至第二目标扭矩,调整动力维持电机至第三目标扭矩。本申请实施例提供一种双电机换挡方法及控制系统,以解决相关技术中双电机换挡过程中,两个电机同时驱动,过程繁琐复杂的问题。
