A clutch aging detection method and system

Abstract

The present invention relates to the technical field of detection of automobile clutches, in particular to a clutch aging detection method, in which a position sensor is installed on the clutch in advance to collect the displacement of the power components in the clutch and form a displacement signal; it also includes the following steps: processing The controller reads the flywheel torque, engine speed and displacement signal output by the engine; the processor calculates the current transmission torque of the clutch according to the flywheel torque and engine speed; the processor calculates the reduction of the transmission torque of the clutch at the same position based on the displacement signal , and then calculate the wear and aging value of the clutch according to the decrease. Beneficial effects of the technical solution of the present invention: provide a system and method for automatically detecting the aging degree of the clutch, so as to judge the aging and wear degree of the clutch more accurately without disassembling the clutch, so that the car maintenance personnel can replace the severely aging clutch in time. The clutch improves the safety performance of the car.

Description

technical field [0001] The invention relates to the technical field of detection of automobile clutches, in particular to a method and system for detecting the aging of clutches. Background technique [0002] In a car with a clutch, whether it is a manual transmission, an integrated manual transmission or a dual clutch transmission, the clutch is required to realize the transmission and disconnection of power between the transmission system and the engine. With the increase of the service life of the car, the clutch tends to continue to wear and age during its life cycle. After the clutch wears and ages, the characteristics of its transmission torque will also have a huge change, which will affect the handling, power and even the safety of the vehicle. adverse effects.

Problems solved by technology

With the increase of the service life of the car, the clutch tends to continue to wear and age during its life cycle. After the clutch wears and ages, its transmission torque characteristics will also undergo a huge change, which will have a great impact on the handling, power and even safety of the vehicle. bad influence

However, the aging degree of the clutch is closely related to the driver's driving habits. Since the driving conditions and habits of each driver are different, the wear and aging degrees of different vehicles of the same model are also very different.

The wear and aging degree of the clutch can only be estimated by the driver's own experience, and the operation mode cannot be effectively optimized according to the wear and aging condition
