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, the large 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

The invention discloses an integrated control system and method of a low-speed vehicle. The integrated control system of the low-speed vehicle is characterized in that the integrated control system comprises a driving intention recognition module, a vehicle speed information acquisition module, a low-speed vehicle integrated controller, a torque and rotating speed control module, a gear-shifting control module and a motor; the input end of the low-speed vehicle integrated controller is connected with the output end of the driving intention recognition module and the output end of the vehicle speed information acquisition module; the output end of the low-speed vehicle integrated controller is connected with the input end of the torque and rotating speed control module and the input end ofthe gear-shifting control module; and the input end of the motor is connected with the output end of the torque and rotating speed control module and the output end of the gear-shifting control module. By adoption of the integrated control system and method of the low-speed vehicle, automatic gear shifting of the vehicle is achieved, and the service life of a gearbox is prolonged.
Description
technical field [0001] The invention relates to the technical field of vehicle shift control, in particular to an integrated low-speed vehicle control system and method. 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, the large 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...
