Pressure compensation method and device for clutch hydraulic system

The present invention provides a clutch hydraulic system pressure compensation method and device. This method monitors the actual pressure of the clutch hydraulic system in real time and compares it with the pressures corresponding to the clutch half-engagement point KP and the clutch nonlinear point VKP. If the actual pressure is greater than the pressure corresponding to KP but less than the pressure corresponding to VKP, a base compensation amount is determined based on the pressure corresponding to VKP and the actual pressure. A correction coefficient is determined based on the current valve body oil temperature and the target pressure change rate. The clutch hydraulic system is pressure compensated using the base compensation amount and the correction coefficient. In this solution, by monitoring the actual pressure in real time and comparing it with the pressures corresponding to the clutch half-engagement point KP and the clutch nonlinear point VKP, pressure compensation is performed on the clutch hydraulic system when the actual pressure is between the pressures corresponding to KP and VKP, thereby reducing response delays and errors in the clutch hydraulic system.

Method and device for determining hydraulic clutch engagement point, vehicle, equipment and medium

This application proposes a method, device, vehicle, equipment, and medium for determining the engagement point of a hydraulic clutch, relating to the field of clutch control technology. The method analyzes whether the pressure value change trend during the oil filling process conforms to a preset trend. This preset trend characterizes the pressure value change trend during the oil filling process as the pressure value transitions from a relatively stable rate of increase to a state of continuously increasing rate of increase. Based on this, the inflection point where the pressure value changes from a stable increase to rapid pressure increase is determined throughout the entire oil filling and pressure building process. This inflection point can be considered as the point where the pressure in the hydraulic circuit exhibits a rapid upward trend due to the resistance of the hydraulic clutch's driving end during engagement. The pressure value corresponding to this point can be used as the pressure value of the clutch engagement point. This method eliminates the need to start high-pressure equipment such as motors / engines, allowing operation under low-pressure conditions, reducing influencing factors, and ensuring the stability and accuracy of self-learning.
