Abstract

The invention relates to a PWM signal transmission method and system for an automobile seat ventilation system, and the method comprises the steps: carrying out the signal filtering of a pre-communication bit and a communication calibration bit of a PWM signal, and defining gears of different rotating speeds through function definition data; the beneficial effects are that the problem of unstablerotating speed caused by PWM signal interference deformity is solved; after the fan receives the standard signal, a preset target rotating speed is executed; and when an interfered malformation signalis received, the malformation signal is not responded, the original rotating speed gear is kept, and the purpose of filtering the signal is achieved.

Description

technical field [0001] The present application relates to the technical field of driving assistance, in particular to a PWM signal transmission method and a system for an automobile seat ventilation system. Background technique [0002] With the rapid development of economy and society, automobiles have entered the homes of ordinary people. Nowadays, automobiles are not just a means of transportation for ordinary people. People pay more and more attention to the comfort and functionality of automobiles when riding in automobiles. In modern cities, traffic congestion is a common problem, which causes people to travel for a long time, causing the temperature between the body and the seat to be high. According to actual experience, when the temperature is above 25°C, driving for 40 minutes continuously will cause obvious discomfort in the seat and back of the body, which will lead to road rage such as irritability and anxiety. Therefore, a system is urgently needed to reduce th...
