[CN 201810812852.9] Pressure State Prediction Method for Target Section of Hydro-mechanical Stepless Transmission
[CN 201810812852.9] Hydromechanical Stepless Transmission Target Section Pressure State Prediction Method Title: Hydromechanical Stepless Transmission Target Section Pressure State Prediction Method Application Number: CN 201810812852.9 Applicant: Yanshan University Application Date: 2018-7-23 Patent Type: Invention Application The present invention provides a hydromechanical stepless transmission target section pressure state prediction method, which includes the following steps: Step 1): Obtain the real-time observation value of the current section state; step 2): Judge the timing of segment change; Step 3): According to the real-time observation value of the current segment state and the power flow characteristics of the target segment, the target segment power loss prediction value is obtained through the target segment power loss prediction model; Combined with the real-time observation value of the current segment state and the power loss prediction value of the target segment, the target segment pressure state prediction result is obtained by using the hydraulic mechanical stepless transmission target segment pressure state prediction model. Using the method of the present invention, the hydraulic mechanical stepless transmission work in the current segment can predict the target segment pressure state, to guide the hydraulic mechanical stepless transmission to achieve full-power power change segment, according to this prediction method, the output speed before and after the change segment no change, the power transition is smooth, the quality of the change segment is significantly improved.
