Hybrid drive system with AMT transmission

Abstract

The invention provides a hybrid drive system with an AMT transmission. The system comprises a first driving portion, a second driving portion and a control portion; the first driving portion and the second driving portion are connected, the first driving portion and the second driving portion are both connected with power batteries, a power source of the first driving portion is electric power andfuel power hybrid power, and the power source of the second driving portion is pure electric power; the control portion controls the second driving portion to operate separately or the first drivingportion and the second driving portion to cooperate with each other to simultaneously operate, monitors electricity quantity of the power battery and controls the charging, blackout and discharging. The first driving portion and the second driving portion can be operated separately or simultaneously in cooperation with each other. In the shifting state, the second driving portion can provide driving force to ensure that shifting is conducted when the power is not interrupted, thereby ensuring driving comfort and safety; the overall layout of the system is simple, which is conducive to large-scale improvement on the basis of existing AMT transmissions.

Description

technical field [0001] The present invention relates to hybrid drive systems, and more particularly to hybrid systems with electromechanical automatic transmissions (AMT). Background technique [0002] In modern society, people use cars on a large scale. While a large number of automobiles provide convenience for life, they also cause huge energy consumption and heavy ecological pressure. With the further aggravation of energy shortage and global warming, energy saving and emission reduction have become the focus of attention all over the world. Reducing dependence on energy and realizing energy conservation and emission reduction has become an urgent problem to be solved for the sustainable development of the world economy. Therefore, hybrid electric vehicles and pure electric vehicles have become the development trend of today's automobile industry. [0003] At present, the hybrid transmissions on the market, in terms of structure, include: CVT hybrid transmissions, DCT...

AI Technical Summary

Problems solved by technology

[0004] However, the traditional AMT gearbox is driven by the engine independently and (the drive motor position is behind the clutch, before the gearbox) in the hybrid drive mode, the power interruption phenomenon occurs during the shifting process - such as: AMT gearbox 2nd gear is switched to 3rd gear During the process, the clutch needs to be disconnected first, and then the 2nd gear synchronizer is placed in neutral (disconnecting the combination with the 2nd gear driven gear). During this process, the power of the engine or the motor cannot drive the wheels to rotate, resulting in power interruption , which in turn affects the comfort of the vehicle, and may affect the driving safety of the vehicle in the climbing section
