Embodiment Construction
[0048] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0049] Please refer to figure 1 , figure 1 It is a schematic diagram of the hardware structure of the synchronizer control device provided in each embodiment of the present invention. The synchronizer control device includes components such as a communication module 01 , a memory 02 and a processor 03 . Those skilled in the art can understand that, figure 1 The synchronizer control shown in may also include more or fewer components than shown, or combine certain components, or have different component arrangements. Wherein, the processor 03 is respectively connected to the memory 02 and the communication module 01 , the memory 02 stores a computer program, and the computer program is executed by the processor 03 at the same time.
[0050] The communication module 01 can be connected with external devices through t...

The invention discloses a synchronizer control method, a synchronizer control device, and a storage medium. The synchronizer control method includes the steps that a shift instruction with shift gearsis received, and gear engaging pressure of a shift fork is controlled according to a first preset strategy to reduce a real-time speed difference of a synchronous sleeve of the synchronizer corresponding to the shift gears and a combining tooth to a first preset threshold value. When the real-time speed difference is reduced to the first preset threshold value, the gear engaging pressure of the shift fork is controlled according to a second preset strategy, and a clutch corresponding to the shift gears is subjected to oil charge according to preset oil charge pressure so as to make the synchronous sleeve mesh with the combing tooth to finish shift. According to the synchronizer control method, the synchronizer control device and the storage medium, the problem that the shift time of an existing double-clutch automatic transmission is long is solved.
Description
technical field [0001] The present invention relates to the field of vehicles, in particular to a synchronizer control method, a synchronizer control device and a computer-readable storage medium. Background technique [0002] Dual-clutch automatic transmission includes two coaxial nested or parallel arranged clutches, coaxial, inner and outer inner and outer nested input shafts and outer input shafts, output shafts, multiple synchronizer devices arranged on the output shafts, multiple It consists of a shift fork and a differential. The driving gears of the odd and even gears of the transmission are arranged on the inner and outer input shafts respectively, through the switching of two clutches and the actions of different synchronizers, torque conversion and output are realized. The main process of gear shifting in the prior art is to apply gear shifting pressure to the shift fork to push the synchronizer to move and continue to push the synchronizer to mesh with the gear ...
