Abstract

The invention provides an AMT single-motor hybrid transmission which comprises an engine, a driving motor, an engine input shaft connected with the output end of the engine through a clutch, a motor input shaft connected with the output end of the driving motor through a gear and an output shaft connected with a vehicle transmission shaft, and the output shaft is coaxially connected with the motor input shaft through a first synchronizer, the engine input shaft is in transmission connection with the motor input shaft or output shaft through a gear. In the engine gear shifting process, the engine torque can be compensated through the driving motor, power transmission in the gear shifting process is guaranteed, the problem of power interruption of AMT gear shifting is solved, and the whole vehicle driving feeling is improved. When the electric quantity of the battery is enough and the required power of the whole vehicle is large, the transmission participates in driving, engine transient working conditions are reduced and thus oil consumption is reduced. The problem that reversing cannot be achieved due to the fact that the electric quantity of the non-plug-in hybrid vehicle is not enough after reversing for a long time is solved, and practicability is high. The invention further provides a driving control method of the AMT single-motor hybrid transmission.

Description

technical field [0001] The invention relates to an AMT single-motor hybrid transmission and a drive control method thereof, and the technical field of hybrid drives. Background technique [0002] With the vigorous implementation of the national energy conservation and emission reduction strategy and the introduction of the goals of carbon peaking in 2030 and carbon neutrality in 2060, the automobile industry, as one of the major carbon emitters, is facing a strong emission reduction task. The automobile industry is currently undergoing electrification and hybrid transformation. Limited by the current maturity of the battery industry and related infrastructure and cost constraints, hybrid power will still be a very promising technology in the short to medium term. At present, there are a lot of hybrid solutions applied to passenger cars, including THS, IMMD, DHT, Px, etc., and have achieved mass production applications. However, in the field of commercial vehicles, especially...
