Description

Hybrid power driving system and vehicle
Technical Field
The invention belongs to the technical field of power, and particularly relates to a hybrid power driving system and a vehicle.
Background
Hybrid drive systems may improve vehicle economy in a number of ways. For example, the engine may be turned off during idle, deceleration, or braking, and travel in an electric-only drive mode to eliminate efficiency losses due to engine drag. Additionally, energy stored in the power battery, generated by regenerative braking or generated by the electric machine during engine operation, may be utilized in an electric-only drive mode, or to supplement the torque or power of the engine in a hybrid drive mode.
Hybrid vehicles are capable of being driven with at least two different powers, and most of the hybrid vehicles today employ a hybrid electric drive system that includes an engine powered from fuel and an electric motor driven by electric power. In order to improve the combustion efficiency of the engine to the maximum extent, hybrid power driving systems developed by many automobile manufacturers all adopt a dual-motor structure, namely, a generator is added besides a driving motor. Because the engine, the generator and the driving motor exist at the same time, the connection and control among the engine, the generator and the driving motor directly influence the performance of the hybrid vehicle.
The prior hybrid power driving system comprises an engine, a power motor and an auxiliary motor, the engine outputs power to wheels of the hybrid electric vehicle through the double clutches, the second input shaft is coaxially sleeved on the first input shaft, the engine is arranged to be selectively connected with one of the first input shaft and the second input shaft through the double clutches, a gear driving gear is arranged on each of the first input shaft and the second input shaft, the first output shaft and the second output shaft are arranged in parallel with the first input shaft, a gear driven gear is arranged on each of the first output shaft and the second output shaft, the gear driven gears are correspondingly meshed with the gear driving gears, the power motor is arranged to be linked with the first input shaft or the second input shaft, and the auxiliary motor is connected with the engine and generates power under the driving of the engine to charge the power battery; although two motors are arranged, the two motors are functionally distinguished, the power motor is only used for driving, the auxiliary motor is only used for generating power, the charging efficiency is low, and the hybrid power driving system cannot be effectively kept to work in a high-efficiency range due to the fact that the engine only has two power output gears.
In addition, the existing hybrid power driving system is difficult to solve the efficiency problem of low-speed and medium-low-speed engines, the electric balance problem and the high-speed dynamic problem of the engines at the same time. The engine is difficult to work in a fuel economy area, and the vehicle economy is poor.

In another aspect, an embodiment of the present invention further provides a vehicle, which includes the hybrid drive system.
The hybrid power driving system and the vehicle of the embodiment of the invention can selectively transmit power to the output shaft through one gear set of the first gear set, the second gear set and the third gear set by controlling the connection or disconnection of the first clutch, the second clutch and the third clutch, so that the engine can output three speed ratios, the three-gear speed change of the engine is realized, the motor can be used for generating power or driving, a pure electric driving mode, a parallel driving mode and a direct engine driving mode are realized, and a plurality of driving modes have a plurality of gears, different driving force requirements can be met, the engine can work in a region with higher fuel economy as far as possible, the motor can work in a region with higher economy, the problems of engine efficiency and electric balance at low speed and medium speed and the problem of power startability at high speed are solved, the system has high working efficiency, so that the vehicle economy is improved; the hybrid power driving system is simple and compact in structure, the number of used parts is small, the structural complexity of the hybrid power driving system is reduced, energy transmission loss is small, and system efficiency is improved.
