Problems solved by technology

[0003] Under the existing technology, due to the consistency of the product and the wear and tear, the clutch on the whole vehicle will show that the coupling time is too long or the shifting quality is poor and there is impact, which causes passengers to complain
[0004] The solution to the above situation is to optimize the calibratable data in the automatic transmission control unit, but currently there is no adaptive control system or method for wet clutches for continuously variable transmissions

Embodiment 1

[0023] Embodiment 1: as attached figure 1 As shown, an adaptive control system for a wet clutch for a continuously variable transmission, the adaptive control system includes an actual filling time monitoring module 101, a standard filling time setting module 102 and an application layer software function module 103, wherein, The actual filling time monitoring module 101 is used to collect information on the actual coupling time of the clutch; the standard filling time setting module 102 is used to set the target coupling time of the clutch; the application layer software function module 103 is used to compare the actual filling time The actual engagement time of the clutch collected by the monitoring module 101 is compared with the target engagement time of the clutch set in the standard oil filling time setting module 102 , and the comparison result is sent to the application layer software function module 103 .

[0024] The adaptive control system also includes the bottom l...

Embodiment 2

[0027] as attached figure 2 As shown, an adaptive control method of a wet clutch for a continuously variable transmission of the present invention includes the following procedures:

[0028] 201. Read the data stored in the EEPROM in the adaptive control system from the oil-filled oil pressure data table of the wet clutch of the continuously variable transmission.

[0029] 202. The adaptive control system collects information on the actual engagement time of the clutch and information on the current working condition of the vehicle.

[0030] 203. The adaptive control system compares the collected actual coupling time of the clutch with the preset target coupling time, and judges whether the working condition information meets the adaptive conditions of the adaptive control system. If the comparison result exceeds the target coupling time range and the working condition information satisfies the adaptive conditions of the adaptive control system, then execute step 204. Here, ...

Abstract

The invention relates to a self-adaptive control method and control system of a wet clutch for a continuously variable transmission, belonging to the control field of wet clutches for automobile continuously variable transmissions. In the clutch control process, the actual combination time of the clutch is controlled in real time, in the meantime, if other conditions, such as speed, accelerator pedal and the like, meet a self-adaptive condition, a self-adaptive function is activated, and an oil charging pressure value needed to be regulated is stored in an electrically erasable, programmable read-only memory which plays a role of correcting rating data in application software and controls the actual combination time of the clutch to meet the requirement of target combination time. Through the technical scheme provided by the invention, when an automatic transmission control unit works normally, the control system can carry out online intelligent parameter adjusting and automatically optimize the combination time of the clutch and the gear shifting quality, thereby having a strong self-adaptive capability and ensuring that the result can completely meet a control requirement. The realization of a self-adaptive algorithm in the control system can remain the combination quality of the clutch of the automatic transmission to have optimum performance within the life cycle and ensure the stability of shifting time and quality.

Description

technical field [0001] The invention relates to the field of wet clutch control for a continuously variable transmission for automobiles, and specifically provides an adaptive control method and a control system for a wet clutch for a continuously variable transmission. Background technique [0002] In the field of continuously variable automatic transmission control, the control object of the wet clutch is the oil pressure, and the control target is the clutch engagement time and shift quality, that is, to meet the comfort and smoothness of the shift start of the vehicle during use. [0003] Under the prior art, due to the consistency of the product and wear and tear, the clutch on the whole vehicle may show that the coupling time is too long or the shifting quality is poor, and there is an impact, which causes passengers to complain. [0004] The solution to the above situation is to optimize the calibratable data in the automatic transmission control unit, but currently t...
