Problems solved by technology

However, the existing clutch control device cannot consider the influence of the number of engagements on wear, and at the same time, it cannot also consider the change of the friction coefficient during each engagement process. The control accuracy is poor, resulting in poor clutch performance.

An inlet of the oil pump communicates with the oil tank through a pipeline, an outlet of the oil pump is connected with an inlet of the electromagnetic proportion valve, an outlet of the electromagnetic proportion valve is connected with the wet multi-plate clutch, and the electromagnetic proportion valve is connected with the PID controller. According to the control device and control method, the influence of the number of times of engagement on wear is fully considered, the friction coefficient change in each engagement process is considered, the loss of the friction coefficient of friction plates of the clutch can be accurately detected, and the engagement pressure compensation amount can be accurately applied; and accurate control over the clutch is achieved, and the work performance of the clutch is improved.

Description

technical field [0001] The invention belongs to the technical field of clutch control equipment, and in particular relates to a control device and a control method for compensating the friction coefficient loss of a wet multi-plate clutch. Background technique [0002] During the use of the clutch, as the number of engagements of the clutch increases, the friction plates of the clutch will gradually wear out, and the friction coefficient of the clutch will decrease. At the same time, considering that the friction coefficient of the clutch is greatly affected by temperature, clutch speed difference, etc. during the engagement process, it is necessary to perform real-time compensation control for each engagement in order to realize efficient clutch automatic control. However, the existing clutch control device cannot consider the influence of the number of engagements on wear, and at the same time, cannot also consider the change of the friction coefficient during each engagem...
