Example Embodiment

[0051] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals indicate the same or similar parameters or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary, and are only used to explain the present invention, and cannot be construed as limiting the present invention.

[0052] The present invention provides an oil-filled adaptive control method and system for wet clutches, which can make the actual pressure of the clutch reach the kisspoint pressure of the clutch from 0kpa within a specified time. In addition, an oil-filled adaptive control system is added, which can Solve the problem that the kisspoint point changes due to the change of the clutch state or oil temperature, which makes the actual pressure of the clutch inappropriate, resulting in insufficient power ...

Abstract

The invention discloses an oil charging self-adaptive control method and a system for a wet clutch. The method comprises the following steps: a present clutch oil charging state is obtained under a peristalsis working condition; when the present clutch oil charging state is an oil charging control state, a present clutch target pressure is obtained; in a preset adjusting time length, the present clutch target pressure is adjusted to a semi-joint point of the clutch; after the adjustment is finished, in a preset integral control time length, a correction parameter of an oil charging compensation value is obtained according to the relation between a difference value of the semi-joint point and actual pressure of the clutch and the correction parameter of the oil charging compensation value; the oil charging compensation value is corrected according to the correction parameter of the oil charging compensation value to obtain a corrected oil charging compensation value; and target pressure of the clutch is adjusted according to the corrected oil charging compensation value. The method can adjust the target pressure value of the clutch to the semi-joint point in the stated time, and can prevent such problems as vehicle impact or even suppressed flameout of an engine.

Description

Technical field [0001] The present invention relates to the field of clutch control, in particular to an oil-filled adaptive control method and system for wet clutches. Background technique [0002] Wet clutches are widely used in automatic transmissions, and their working principles are as follows: During the clutch coupling process, pressure oil enters one side of the clutch cylinder through the oil passage, pushing the piston to the other side to compress the friction plate, so that the clutch is active / The slave side realizes synchronous movement. During the clutch oil filling process, the pressure relief hole is sealed by the barrier, so there is no pressure oil leakage; while in the oil drain stage, the barrier no longer blocks the pressure relief hole under the action of centrifugal force, and opens the pressure relief hole to make the clutch active / The driven side is separated. [0003] Creeping conditions refer to the conditions in which the vehicle can move forward or...
