Technical field
The present invention relates to the calculations of automobile technical field more particularly to a kind of automobile clutch torque increase position and open position
Method.
Background technique
The clutch system of automobile adjusts clutch open position according to different situations, and the acquisition and processing of clutch signal are to row
Vehicle stability is most important, can Quick Acquisition to clutch signal, clutch failure and in time clutch signal is handled, to vehicle
The safety of traveling plays very big effect.
But traditional clutch system is difficult to feed back clutch engagement signal and handled, it is difficult to clutch open position into
Row is adjusted, and reduces the stability for improving driver drives vehicle, comfort, safety, it is difficult to meet vehicle to start clutch
Every service performance requirement.
Summary of the invention
It the purpose of the present invention is to solve existing in the prior art is difficult to that clutch open position is adjusted, drop
The low stability for improving driver drives vehicle, comfort, safety, it is difficult to meet vehicle to every usability of start clutch
The algorithm that can be required.
To achieve the goals above, present invention employs following technical solutions:
