  • Method for switching modes of electromechanical transmission system
    Patent number: 10967730
    Abstract: The present invention discloses a method for switching modes of an electromechanical transmission system which includes a clutch CL0, a motor A, a clutch CL1, a brake B1, a motor B and three planet rows K1, K2 and K3. The electromechanical transmission system according to the present invention achieves two different structural modes of EVT1 and EVT2 by changing states of the clutch CL0 and the brake B1. The 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.
