Abstract

The invention discloses a hybrid electric system adopting a double-rotor motor. The hybrid electric system comprises the double-rotor motor, a double-motor controller and an engine, wherein the double-rotor motor comprises an inner rotor motor and an outer rotor motor; the inner rotor motor is engaged with a power output shaft or a four-speed gear bank through an inner rotor motor reduction gear bank; the outer rotor motor is connected with the power output shaft through an outer rotor motor reduction gear bank; the double-motor controller is used for independently controlling the inner rotor motor and the outer rotor motor, and is connected with a power battery; an output shaft of the engine is engaged with one of a one-speed gear bank, a two-speed gear bank, a three-speed gear bank and the four-speed gear bank through a clutch, or not engaged with the one-speed gear bank, the two-speed gear bank, the three-speed gear bank and the four-speed gear bank; the one-speed gear bank, the two-speed gear bank and the three-speed gear bank are connected with the power output shaft; the four-speed gear bank is engaged with the power output shaft or the inner rotor motor reduction gear bank. The hybrid electric system adopting the double-rotor motor and an implementation method of the hybrid electric system adopting the double-rotor motor have the characteristics of compact structure, high integration of the system, high efficiency of the vehicle, good fuel economy, smoothness in low-temperature coldstart of the engine and good grade ability at a low speed.

Description

technical field [0001] The present application relates to a power system of a hybrid electric vehicle. Background technique [0002] A hybrid vehicle is a vehicle that uses more than two sources of energy. The most common hybrid electric vehicle (HEV for short) has an engine and an electric motor, the engine consumes fuel, and the electric motor consumes electric energy of the power battery. [0003] HEV mainly has three types of hybrid systems: Series Hybrid, Parallel Hybrid and Combined Hybrid or Series-Parallel Hybrid or Parallel-Series Hybrid. [0004] The series hybrid system only uses the electric motor as the driving device, and the engine is only used as a generator to charge the power battery and supply power to the electric motor. Since the engine does not directly participate in the driving of the vehicle and is limited by the power of the electric motor, the dynamic performance of the vehicle is generally poor. [0005] A parallel hybrid system uses the engine...
