Clutch torque and pressure self-adaptive method and system

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...

Problems solved by technology

[0003] If the direct relationship between torque and pressure is not corrected, the following situations may occur: 1. The pressure between the clutch discs is too small, resulting in ablation of the clutch

2. The pressure between the clutch discs is too high, causing the gearbox to back-drag the engine, forming a rigid connection of the transmission system. If the road surface is slightly uneven, it will be transmitted to the entire vehicle, causing an impact
