Abstract

The invention provides an AMT gearbox gear shifting control system and a control method. The system comprises an electromagnetic brake, and an engine, a clutch assembly, an engine output shaft, an auxiliary gearbox and an AMT gearbox which are connected in sequence; the auxiliary gearbox comprises a one-way clutch and a gearbox input shaft; and the engine output shaft is connected with a gearbox input shaft in a co-rotating mode or connected with the gearbox input shaft through the one-way clutch. When an AMT gearbox needs to be upshifted or forcibly downshifted, the engine output shaft is connected with the gearbox input shaft through the one-way clutch, then gear shifting operation is conducted, in the gear shifting operation process, a clutch of the clutch assembly is kept in a closed state, and in the upshifting gear shifting process, the rotating speed of an engine crankshaft is adjusted in an auxiliary mode through the electromagnetic brake. According to the AMT gearbox gear shifting control system provided by the invention, the frustration caused by power interruption during gear shifting of a traditional AMT gearbox is eliminated, the gear shifting power interruption time of the AMT gearbox is greatly shortened, the gear shifting speed is increased, and the driving comfort is improved.

Description

technical field [0001] The invention relates to the technical field of automobile power, in particular to an AMT gearbox shift control system and control method. Background technique [0002] When the car is in the process of upshifting or downshifting, the clutch needs to be separated or disconnected first, and then the gear is removed and shifted. After the shift is completed, the clutch is closed so that the power can be transmitted to the wheels through the clutch. Due to the disengagement of the clutch, there will be a power interruption process in the above process, and the longer the power interruption process, the more it will affect the drivability and driving comfort of the car. Contents of the invention [0003] In view of the above-mentioned problems existing in the prior art, the purpose of the present invention is to provide a shift control system and control method for an AMT gearbox, which eliminates the frustration caused by power interruption when shiftin...
