Abstract

The invention discloses a hybrid power system and a control method thereof. The hybrid power system comprises an engine, a planetary gear train, a first motor, a second motor, a main shaft, a first gear train, a second gear train, a synchronizer and a power supply assembly, the planetary gear train is located in a rotor of the first motor, a gear ring is fixedly connected with the rotor of the first motor, a center wheel is coaxially connected with an output shaft of the engine, a planetary rack is coaxially connected with an input gear of the second gear train, the rotor of the first motor isconnected with the first gear train in a transmission mode, the main shaft is connected with an output shaft of the second motor in a transmission mode, the main shaft is connected with wheels in a transmission mode, and the synchronizer can be switched among a first state, a second state, and a third state. According to the hybrid power system and the control method thereof, a variety of workingmodes can be achieved, the action of the engine, the first motor and the second motor is fully played, and the working efficiency of the hybrid power system is improved.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a hybrid power system and a control method. Background technique [0002] As a fast-paced and efficient means of transportation in life, the number of cars has increased year by year in recent years. However, most traditional cars use fossil fuels (such as gasoline, diesel, etc.) Cause pollution, do not meet the requirements of energy saving and environmental protection. Therefore, it is urgent to use non-polluting new energy sources (such as electric energy) to replace fossil fuels to provide power for automobiles. [0003] The prior art provides a hybrid power system suitable for automobiles, including: an engine, a first motor, a second motor and a first planetary gear train. Wherein, the output shaft of the engine is connected coaxially with the planetary gear carrier of the first planetary gear train, the output shaft of the first motor is connected coaxially with the sun gear o...
