The invention discloses a hybrid electric vehicle power system and a power transmission method and relates to the technical field of hybrid electric vehicles. The system comprises an engine, a motor,a differential mechanism, a gearbox, a clutch and a multimode hybrid power switching mechanism, the clutch is connected with an output shaft of the engine and an input shaft of the gearbox, and the multimode hybrid power switching mechanism is arranged on an output shaft of the engine. The output shaft of the gearbox is connected with the multi-mode hybrid power switching mechanism and then connected with the differential mechanism, and the motor is connected to an output shaft of the engine by being connected with the multi-mode hybrid power switching mechanism; a clutch is matched with the multimode hybrid power switching mechanism to control the combination or separation of the engine, the motor, the differential mechanism and the gearbox. By applying the system, idling charging, enginequick starting, gear shifting torque compensation, driving assistance, driving power generation, braking energy recovery or a pure electric working mode can be achieved.
