Problems solved by technology
New energy vehicles on the market now use single-speed ratio gearboxes, which cannot effectively adjust the speed according to road conditions and vehicle speeds, reducing the service life of the gearbox
[0003] When a new energy vehicle starts at a low speed, its motor torque will cause rapid wear and ablation of the clutch, so the clutchless transmission control system can be well applied, but the synchronization and process control of the motor during the shifting process are more complicated and important , it is easy to cause the problem of long shifting time and insufficient power

Description
technical field [0001] The invention relates to the technical field of automobile shift control, in particular to an automobile shift control system and method based on a two-speed transmission. Background technique [0002] With the development of the times and the enhancement of environmental awareness, new energy vehicles are getting more and more attention from people, and their service life and noise reduction need to be improved. The new energy vehicles on the market now use single-speed ratio gearboxes, which cannot effectively adjust the speed according to road conditions and vehicle speeds, which reduces the service life of the gearbox. [0003] When a new energy vehicle starts at a low speed, its motor torque will cause rapid wear and ablation of the clutch, so the clutchless transmission control system can be well applied, but the synchronization and process control of the motor during the shifting process are more complicated and important , It is easy to cause ...
