Abstract

The invention provides a hybrid power system and a vehicle. A gear ring of a first planetary gear train of the hybrid power system is coaxially arranged with a gear ring of a second planetary gear train, and is connected with the same as a whole; an engine is connected with a planet carrier of the first planetary gear train; an output shaft of a first motor is connected with a sun gear of the first planetary gear train; an output shaft of a second motor is connected with a sun gear of the second planetary gear train; an output transmission gear set is connected with a planet carrier of the second planetary gear train; a first torque transfer mechanism is arranged among the gear ring of the first planetary gear train, the gear ring of the second planetary gear train and a stationary component of the vehicle; and a second torque transfer mechanism is arranged between an output shaft of the engine and the output shaft of the first motor. The engine, the first motor and the second motor are connected by using the first planetary gear train and the second planetary gear train; and the joint and the separation of the first torque transfer structure and the second torque transfer structure are controlled to realize the switchover of different driving or working modes.

Description

technical field [0001] The invention relates to a power system of an automobile, in particular to a hybrid power system of a hybrid electric vehicle and an automobile using the hybrid power system. Background technique [0002] A hybrid vehicle can be effectively driven by at least two different power sources. At present, most hybrid vehicles are gasoline-electric hybrids, which include an engine powered by fuel and an electric motor driven by electricity. In order to improve the combustion efficiency of the engine to the greatest extent, the hybrid power system developed by many domestic and foreign automobile manufacturers adopts a dual-motor structure, that is, in addition to the drive motor, an additional generator is added. Since there are engine, generator and drive motor at the same time, the connection and control between the three will directly affect the performance of the hybrid vehicle. The coupling of the dual-motor hybrid system in the prior art is mainly based...
