Abstract
The present invention discloses a method for switching modes of an electromechanical transmission system which includes a clutch CLa motor A, a clutch CLa brake Ba motor B and three planet rows KKand KThe electromechanical transmission system according to the present invention achieves two different structural modes of EVT1 and EVT2 by changing states of the clutch CLand the brake BThe EVT1 mode is mainly a system running state at a low vehicle speed under a high driving torque demand, and the EVT2 mode is mainly a system driving state at a high vehicle speed under a low driving torque demand. Mode switching without speed difference and power interruption can be achieved by switching vehicle speed selection and reasonable adjustment of engine and motor torque.
