[0002] With the development of automobile technology, the requirements for driving comfort and safety are constantly increasing. Traditional manual transmissions require the driver to manually operate the clutch, which may increase driving difficulty and risk in complex road conditions or severe weather conditions. In order to improve driving convenience and safety, the demand for automated clutch control systems is growing.

[0003] Existing automobile clutch control systems usually require the driver to manually operate the clutch pedal to control the engagement and disengagement of the clutch, and control the automatic engagement and disengagement of the clutch through electronic signals to reduce the driver's operating burden, including speed sensors, vehicle speed sensors, etc., which are used to monitor the vehicle status and provide data support. Although the existing clutch control systems have reduced the driver's operating burden to a certain extent, they are inaccurate in identifying driving intentions and may not be able to accurately identify the driver's intentions, resulting in inaccurate shifting timing, and the inability to intelligently adjust the shifting strategy according to actual road conditions, effectively protecting the engine and battery under special road conditions such as uphill or downhill. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a method and device for controlling the use of a vehicle clutch through a computer, which solves the problem that the existing clutch control systems reduce the driver's operating burden to a certain extent, but they do not accurately recognize the driving intention and may not be able to accurately recognize the driver's intention, resulting in inaccurate gear shifting timing, and cannot intelligently adjust the gear shifting strategy according to actual road conditions to effectively protect the engine and battery under special road conditions such as uphill or downhill.
