Mode switching control strategy of dual motors coupled driving on electric vehicles

Based on analyzing the structure and working principle on electric vehicles(EVs)with dual motors coupled by planetary gears,the control strategy of mode switching was proposed.The power interruption problem on EVs with automatic mechanical transmission(AMT)shifting was resolved.Based on the speed-torque characteristics of the planetary gears and the principle of the auxiliary motor's zero speed braking,control features of mode switching were introduced.The mode shifting between the main motor mode and dual ...
