  "textContent": "The present invention discloses a method for switching modes of an electromechanical transmission system which includes a clutch CL a motor A, a clutch CL a brake B a motor B and three planet rows K K and K The electromechanical transmission system according to the present invention achieves two different structural modes of EVT1 and EVT2 by changing states of the clutch CL and the brake B 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.",
