Embodiment Construction

[0048] In order to enable those skilled in the art to further understand the features and technical content of the present invention, the following describes the embodiments of the present invention in detail with reference to the accompanying drawings and embodiments.

[0049] Such as figure 1 Shown is a flow chart of a clutch torque pressure adaptive method according to an embodiment of the present invention, which includes the following steps:

[0050] Step 100: Start.

[0051] Step 101: Detect whether the torque pressure adaptive condition is met; if yes, go to step 102; otherwise, go back to step 101.

[0052] It should be noted that the clutch torque pressure adaptive method provided by the present invention can be implemented by a gearbox control unit.

[0053] Specifically, the torque pressure adaptive conditions include:

[0054] 1) The current clutch is in a slightly slippery state.

[0055] It should be noted that the state of the clutch in a slightly slippery wear state refers...

Abstract

The invention relates to the technical field of transmission control, in particular to a clutch torque and pressure self-adaptive method and system The method comprises the following steps: detecting whether to meet the torque and pressure self-adaptive conditions or not; if YES, performing self-adaptive calculation, wherein the self-adaptive calculation comprises the steps of obtaining engine torque, obtaining current clutch grinding rate, obtaining clutch torque through the engine torque, the current clutch grinding rate and a torque and pressure gauge, dividing different torque intervals according to the engine torque, calculating a clutch torque difference proportional relationship value according to the engine torque and the clutch torque, and setting the frequency of calculation on the clutch torque difference proportional relationship value in the various torque intervals; updating the torque and pressure gauge according to self-adaptive calculation results. Through the clutch torque and pressure self-adaptive method and system provided by the invention, the accuracy and the precision of clutch torque transmission are ensured.

Description

Technical field [0001] The invention relates to the technical field of transmission control, in particular to a clutch torque pressure adaptive method and system. Background technique [0002] The clutch is the hardware that transmits torque. The clutch transmits the corresponding torque by adjusting the pressure between the clutch plates. That is, there is a corresponding relationship between the pressure and the torque in the clutch. As the vehicle mileage increases, the clutch will experience different degrees of wear and aging, and the corresponding direct relationship between pressure and torque will change. Therefore, the corresponding relationship between clutch torque and pressure needs to be corrected to achieve clutch transmission. Accurate torque control. [0003] If the direct correspondence between torque and pressure is not corrected, the following situations may occur: 1. The pressure between the clutch plates is too small, causing the clutch to be ablated. 2. Exce...
