Motor shifting and torque distribution control of a multi-motor driving system in electric construction vehicles

With the rapid development of world economic construction and shortage energy, it has become a hot research issue to realize electrification vehicle driving system improve energy efficiency. Most electric machinery power systems are characterized by low speed high load. The coordinated multiple motors can increase output torque transmission efficiency machine on basis compact layout. A novel configuration vehicles based multi-motor single-speed its distribution control method is presented in this paper. detailed mathematical model established simulation analysis carried out it. results show that proposed with strategy overall condition ensuring force when parameter matching choosing reasonably.
