The invention discloses a double-motor driving assembly and an operation method thereof. The double-motor driving assembly comprises a shell; a shaft rotatably mounted with respect to the housing; a first transmission mechanism connected to the shaft and rotating with the shaft; first and second motors each having an output driving a respective output transmission engaged with the first transmission; means for distributing a torque demand to each motor; means for measuring or estimating first and second temperatures respectively associated with each motor; means for assigning to each motor a maximum torque limit equal to the sum of the maximum torque limits of the first and second motors, respectively, based on the first and second temperatures, in a first mode in which the torque demand assigned to each motor causes the motor to provide an opposite torque to the shaft, and in a second mode in which the torque demand assigned to each motor causes the motor to provide an opposite torque to the shaft. The torque demand assigned to each motor causes the motor to provide torque to the shaft in the same direction, the torque demand assignment changing from the first mode to the second mode at a threshold total torque value, the threshold total torque value being adjusted based on a maximum total torque.
一种双马达驱动组件及其操作方法,包括:壳体;相对于壳体可旋转地安装的轴;连接到轴并与轴一起旋转的第一传动机构;第一、第二马达,各自具有驱动与第一传动机构接合的相应输出传动机构的输出;用于将转矩需求分配给各马达的装置;用于测量或估计分别与各马达相关的第一、第二温度的装置;用于分别基于第一、第二温度向各马达分配等于第一、二马达的最大转矩限制的总和的最大转矩限制的装置,在第一模式下,分配给每个马达的转矩需求使得马达向轴提供相反的转矩,在第二模式下,分配给每个马达的转矩需求使得马达向轴提供沿相同方向的转矩,转矩需求分配在阈值总转矩值处从第一模式改变到第二模式,阈值总转矩值基于最大总转矩进行调整。
