Abstract

The invention provides a method and system for calculating gear wear rate of an automatic transmission. The method comprises the following steps that gear position boundary coordinate values of all gears for gear shifting are determined; a gear fixed point value of each gear is determined on the basis of the gear position boundary coordinate values, and the gear fixed point values comprise gear selecting position fixed point values and gear engaging position fixed point values; the gear fixed point values are compared with a preset threshold value; if the difference between the gear fixed point values and the preset threshold value is within a preset range, the wear rate of each gear is calculated on the basis of the gear position boundary coordinate values. According to the scheme, the wear rate of each gear is calculated by determining the gear position boundary coordinate values of all gears for gear shifting, the phenomena that a transmission is opened manually, and the wear rate of each gear is evaluated manually are avoided, the gear wear rate can be evaluated in time, the driving safety of an automobile is improved, the labor cost is reduced, and the detection time is shortened.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a calculation method and system for the gear wear rate of an automatic transmission. Background technique [0002] With the development of science and technology, automobiles have become one of the main means of transportation in daily life. In the overall structure of the car, the car's gearbox is one of the important configurations of the car. The evaluation of the gear wear rate in the gearbox has become the top priority of car maintenance. Timely acquisition of the gear wear rate in the gearbox can be Effectively avoid traffic accidents. [0003] The current method for evaluating the gear wear rate in the gearbox is to manually open the gearbox to evaluate the wear rate of each gear in the gearbox. However, by manually opening the gearbox to measure the gear wear rate, on the one hand, the disassembly work is heavy, the labor cost is high, and the inspection time is...
