Abstract

The invention relates to a power window control method and system based on a LIN bus. The method includes the steps that a main power window and auxiliary power windows are initialized; the addresses of the auxiliary power windows are distributed automatically according to the on-off condition of a power source; and on-off control over the auxiliary power windows is achieved through the LIN bus by combining the addresses of the auxiliary power windows according to the button state below the main power window. The power window control system comprises a vehicle body controller, a main power window control module, auxiliary power window control modules, the LIN bus and power connecting lines. The main power window control module is connected with the vehicle body controller through the LIN bus. The vehicle body controller is connected with the auxiliary power window control modules through the LIN bus and the power connecting lines. Compared with the prior art, the power window control method and system based on the LIN bus have the advantages that intelligent control is realized, the number of wire harnesses is decreased and cost is reduced.

Description

technical field [0001] The invention relates to the field of automobile control, in particular to an electric window control method and system based on a LIN bus. Background technique [0002] With the development of automobile technology, the application of electric windows is becoming more and more popular. Regardless of whether it has anti-pinch function or one-button lifting function, electric windows can be said to be necessary in modern cars. In order to achieve the convenience of control As well as reducing the amount of connected wiring harnesses, the demand for intelligent control is urgent, and the LIN bus is a low-speed communication system widely used in vehicles, and each sub-node in the system has its fixed address. [0003] Patent CN201210185131 proposes an intelligent car window control method based on the LIN bus. By defining the ID addresses of the four windows and transmitting control commands through the LIN bus, the lifting control of each window can be ...
