Embodiment Construction
[0046] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.
[0047] An AMT shift process control method based on shift slider wear prediction includes: shift slider wear depth prediction and AMT shift multi-objective cooperative control.
[0048] Establish a prediction model for the wear depth of the shift slider under different working conditions, calculate the allowable wear amount based on the failure wear depth and design life of the shift slider, calculate the allowable shift force through the prediction model, and obtain the corresponding allowable shift force. The gear voltage is used as the control limit condition to avoid the failure of the shift slider due to excessive wear within the design life.

The invention discloses an AMT shift process control method based on the wear prediction of the shift slider, which includes: accurately predicting the wear depth of the shift slider, and determining the shift control condition in combination with the design life of the shift slider. The voltage controls the movement of the shift slider to realize the shift operation. Using the finite element simulation test and response surface analysis method, the wear depth prediction model of the shift slider is obtained, which improves the accuracy of the wear depth prediction; the allowable value of the single wear depth is calculated by the failure wear depth of the slider and the design shift times, Substituting it into the predictive model to derive the allowable shift force, taking the corresponding allowable shift voltage as a constraint condition; inputting the wear depth deviation and synchronization time into the fuzzy control strategy to obtain the shift voltage, ensuring that the wear depth of each shift is less than a single The allowable value of the secondary wear depth improves the reliability of the shift slider; at the same time, the model can be set for different shift slider materials and gearbox working conditions, which has high applicability.
Description
technical field [0001] The invention relates to the technical field of AMT shift process control, in particular to an AMT shift process control method based on shift slider wear prediction. Background technique [0002] At present, the control strategy for the AMT shift process is mainly to control the movement of the shift slider through the speed and shift time. By measuring the rotational speed of the engaging sleeve and the engaging ring gear, the rotational speed difference between the engaging sleeve and the engaging ring gear is calculated. Through the shift time and the measured speed or speed difference, the stage of the shift process is judged, so as to control the output voltage of the shift motor, and realize the displacement or speed control of the shift slider. However, the wear of the shift slider is not taken into account in the control process. The shift slider rubs against the adapter sleeve during the shifting process, and the resulting wear will increas...
