The invention provides a self-adaptive control method for electric power balance of an electromechanical composite transmission system, which comprises the following steps of: performing power estimation on auxiliary equipment by adopting an extended Kalman filtering method, and obtaining an optimal estimation value of the total power of each auxiliary equipment; determining dynamic power boundaries of driving motors on two sides of the vehicle when the tandem electromechanical composite transmission system stably runs; and after the steering torque and the acceleration torque generated when the driving motors on the two sides of the vehicle steer and run are decoupled, the acceleration torque of the driving motors on the two sides of the vehicle is dynamically restrained, and the target torque of the driving motors on the two sides of the vehicle is updated. The self-adaptive control method for the electric power balance of the electromechanical composite transmission system has the characteristics of high electric power balance stability, high control precision and the like, and can be widely applied to the field of vehicle control.
