Background
Due to the gradual deterioration of the environment, new energy vehicles, hybrid vehicles and other technologies are increasingly emphasized, and the hybrid vehicles in the related technologies have some defects, so that the hybrid vehicles are difficult to popularize. In the related technology, a single planet row structure is mostly adopted, and only single-mode hybrid power shunting can be realized; the engine torque can only be balanced by the first motor, and the increase of the engine can cause overlarge motor balance torque, so that the application range of the system is limited; when the vehicle runs at a high speed, the first motor reversely rotates to provide power, and the second motor generates electricity, so that electric power circulation is caused, and the efficiency is low; the second motor is directly connected with the output end, and the requirement on the motor is high. For example, first and second generation hybrid systems in Toyota suffer from these problems. In the fourth generation products of the Toyota, the system still has the problem that the single-mode hybrid power split can only be realized because the system is a single planet row; when the vehicle runs at a high speed, the first motor reversely rotates to provide power, and the second motor generates electricity, so that the technical problems of electric power circulation, low efficiency and the like need to be overcome.
