The invention discloses a planetary shunt coupling power system of a hybrid electric vehicle. An engine and a motor respectively drive a planetary mechanism. The planetary mechanism drives a intermediate input gear; the intermediate input gear drives another motor; an intermediate output gear drives a differential mechanism to output power; the engine and the motor are in mutual shunt coupling transmission with the planetary mechanism; on the basis of ensuring that strong torque is output in a medium-low speed state, the medium-high speed section gives play to the power advantage of the motorsto achieve good power complementation; the two motors are used for switching a driving mode and a power generation mode back and forth in different usage scenarios; and a controller adjusts the working states of the engine and the motors according to the actual driving condition of the automobile, the accelerator pedal position signal, the electric quantity state of the vehicle-mounted power supply, the motor efficiency interval and the engine fuel efficiency interval so as to achieve the best power effect and the energy-saving effect. The whole power system is simple in transmission, simplein structure, high in transmission efficiency, high in reliability and high in energy-saving rate.
