Embodiment 1

[0033] Such as figure 1 As shown, a vehicle hybrid coupling system according to Embodiment 1 of the present invention includes: a first planetary gear 16, an engine 1, a generator 6, a first brake 7 and a driving motor 11, wherein the first planetary gear 16 includes three three rotating elements, the three rotating elements are respectively the first sun gear 3, the first planet carrier 4 and the first ring gear 5, the generator 6 is connected with the engine 1 through the first planetary gear 16, and the power of the engine 1 can be passed through The first planetary gear 16 is transmitted to the generator 6, so as to generate electricity and charge the battery. This planetary gear transmission method is not only simple in structure, but also can be arranged in a variety of ways, which helps to efficiently use space and increase the power of the motor to drive the motor. 11 is connected with the differential gear 14 through the transmission device, so as to provide power for...

Embodiment 2

[0056] Such as Figure 5 As shown, the difference between the vehicle hybrid coupling system provided by the second embodiment of the present invention and the first embodiment is that the coupling system further includes a second brake 71, which is connected to the first ring gear 5 for Control the rotation of the first ring gear 5, thereby adding another power working mode, that is, the dual-motor pure electric mode, specifically, as Figure 6 As shown, when the second brake 71 is engaged with the first ring gear 5 so that the first ring gear 5 does not rotate, so that the power of the engine 1 cannot be transmitted and output, the first brake 7 is disconnected from the first planet carrier 4, and the generator 6 works and transmits the power to the differential 14 through the first planetary carrier 4, the first gear pair 41, and the transmission in sequence, and the driving motor 11 works continuously, thus forming a dual-motor pure electric mode. This makes the coupling ...

Abstract

The invention relates to the field of automobiles and discloses an automobile hybrid power coupling system and a control method thereof. According to the coupling system, power on an engine is transferred to a generator by adopting a mode of a first planetary gear, and a first brake is arranged on the first planetary gear, so that the structure of the coupling system is compact and the space is saved; power modes can be switched by virtue of connection or disconnection of the first brake and the first planetary gear; and when the first brake and the first planetary gear are disconnected, speed ratio adjustment of each rotating element in the planetary gear can be realized, the speed ratio between the engine and a motor is adjustable, and the speed ratio adjustment range is relatively large, so that the requirements of power performance and economical performance are met simultaneously. According to the control method, switching of different power modes is controlled by judging the residual electric quantity value of a battery and the automobile speed, so that running requirements under different working conditions are met, and excellent power performance and economical performance can be obtained simultaneously.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an automobile hybrid coupling system and a control method thereof. Background technique [0002] Since entering the 21st century, China's automobile production and sales have continued to grow, and China has become a major automobile country in the world. In this context, the internal growth momentum, consumption structure, production mode and competition pattern of the automobile industry are undergoing profound changes, while the constraints of external factors such as energy, environment and transportation are becoming increasingly severe. As an important direction for the future development of the automobile industry, energy-saving and new energy vehicles will have a profound impact on China's energy, environment, technology, and economy. The development of energy-saving and new energy vehicles (such as gasoline-electric hybrid vehicles) follows China's strategic policy of advocat...
