Problems solved by technology

At present, this field is only designed for the model of the dry clutch structure, and there are few models for real-time monitoring of the temperature of the wet dual clutch, but the structure of the wet dual clutch is obviously different from that of the dry clutch. The cooling environment and cooling method are completely different from the dry clutch, so it is necessary to design a model suitable for the wet dual clutch mechanism

Embodiment Construction

[0078] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0079] The present invention provides a method for determining the temperature of a wet dual-clutch transmission, which includes the following steps:

[0080] ①: Start, to judge whether it is the first run;

[0081] ②: According to the result of the first step, choose to initialize the temperature state quantity of the clutch or read the stored temperature state quantity of the previous cycle;

[0082] ③: Determine the cooling oil flow rate entering the cooling oi...

Abstract

The invention provides a method and device for determining the temperature of a wet dual -clutch transmission. The method comprises the steps that the initial temperature and the cooling oil initial output temperature of a first clutch body and a second clutch body, the cooling oil flow of a dual clutch, the cooling oil input temperature of the dual clutch, the heat input of the first clutch body and the heat input of the second clutch body are determined; the initial temperature and the cooling oil initial output temperature of the first clutch body and the second clutch body, the cooling oil flow and the cooling oil input temperature of the dual clutch, the heat input of the first clutch body and the heat input of the second clutch body are applied to a heat model; the current temperature of the first clutch body and the second clutch body and the cooling oil current output temperature of the dual clutch are calculated through the heat model; and control action is executed through the determined current temperature of the first clutch body and the second clutch body and the determined cooling oil current output temperature of the dual clutch. Thus, the method and device can be used for monitoring the inner temperature of the wet dual clutch in real time.

Description

technical field [0001] The invention relates to the field of temperature measurement of a clutch transmission of a vehicle, in particular to a modeling for determining the temperature of a wet dual-clutch transmission. Background technique [0002] The real-time temperature of the clutch will affect the protection, service life and reliability of the clutch. Therefore, real-time monitoring of the temperature of the clutch provides a basis for controlling the abnormal failure of the clutch. At present, this field is only designed for the model of the dry clutch structure, and there are few models for real-time monitoring of the temperature of the wet dual clutch, but the structure of the wet dual clutch is obviously different from that of the dry clutch. The cooling environment and cooling method are completely different from the dry clutch, so it is necessary to design a model suitable for the wet dual clutch mechanism. Contents of the invention [0003] In order to solv...
