Automobile single door switch matching method and system

Abstract

The invention provides an automobile single-door switch matching method and an automobile single-door switch matching system. The automobile single-door switch matching method comprises the following steps: 1, an MCU (Microprogrammed Control Unit) of each single-door switch respectively acquires communication signals between data lines and different pins of the MCU; and 2, each MCU judges the position of the corresponding single-door switch according to the communication signals. By virtue of the connections between different pins of the MCU of each single-door switch and the corresponding data lines and the input communication signals, judgment on the positions of the single-door switches is finished, i.e., position judgment is finished by virtue of inputting different communication signals, so that the MCUs of three single-gate switches are set as the same structure; as long as the different pins are connected with the data lines, and the input of different communication signals can be finished and judgment on the positions of the single-gate switches is finished. Compared with the prior art, the method and the system have the advantages that MCUs with different structures are arranged for different automobile doors; the MCUs of the single-door switches are set as components with the same structure; position judgment is performed by virtue of different communication signals, so the confusion is avoided, and the assembly accuracy is ensured and the normal operation of automobile doors and windows is ensured.

Description

technical field [0001] The invention relates to the technical field of automobile control methods, in particular to an automobile single-door switch matching method and system. Background technique [0002] With the development of social economy and science and technology, automobiles are more and more favored by people as a new type of means of transportation, and the performance of automobiles is also particularly important. [0003] Specifically, the automobile includes four doors, wherein the door and window switch of the left front door is a centralized control switch, which can control the opening and closing (lifting) of the left front door and window, and can also control the lifting of the other three doors and windows at the same time. Control the lift of the right front, left rear and right rear doors and windows. Of course, the right front, left rear and right rear car doors are also respectively provided with door and window switches corresponding to their resp...

AI Technical Summary

Problems solved by technology

[0005] In view of this, the present invention aims to propose a matching method for single-door switches of automobiles, which solves the problems in the prior art that there is easy confusion between single-door switches, which leads to assembly errors and makes the doors and windows unable to be controlled normally.
