The invention provides a multi-motor driving system and a control method thereof. The system comprises a first motor, a second motor, a third motor and a first intermediate shaft, wherein a first input shaft is connected with the first intermediate shaft through a first input gear pair; the second input shaft is connected with the second intermediate shaft through a second input gear pair; the third input shaft is connected with the third intermediate shaft through a third input gear pair; the first intermediate shaft, the second intermediate shaft and the third intermediate shaft are respectively connected with the output shaft through corresponding transmission gear pairs; the gear shifting devices are fixedly arranged on the first intermediate shaft, the second intermediate shaft and the third intermediate shaft and selectively connect the corresponding intermediate shafts with the gears of the transmission gear pairs on the two sides; an alternate gear shifting scheme is adopted, it is guaranteed that power is not interrupted under all working conditions, and the safety coefficient and comfort of the whole vehicle are improved; in the alternative gear shifting process, two motors replace three motors for power output, and compared with a single motor for replacing double motors for power output, reliability and economical efficiency are higher.
本发明提供一种多电机驱动系统及其控制方法,系统包括:第一、第二、第三电机,第一中间轴,第一输入轴通过第一输入齿轮副连接第一中间轴;第二中间轴,第二输入轴通过第二输入齿轮副连接第二中间轴;第三中间轴,第三输入轴通过第三输入齿轮副连接第三中间轴;输出轴,第一中间轴、第二中间轴及第三中间轴分别通过对应的传动齿轮副连接输出轴;换挡装置,换挡装置固定设置于第一、第二及第三中间轴上且可选择性地将对应中间轴与两侧传动齿轮副的齿轮连接;采用交替换挡方案,保证在各工况下动力不中断,提升整车安全系数及舒适性;并且在交替换挡过程中,通过两电机替代三电机动力输出,相比单电机替代双电机动力输出,更具可靠性和经济性。
