Car scuttle control device

Abstract

The invention provides a skylight controlling unit of a vehicle belonging to the technology and electronics field. The invention resolves the problems of the current vehicle skylight such as single function, poor controlling precision, etc. while controlling a skylight. The skylight controlling unit of vehicle includes a microcontroller. The microcontroller is connected with a power supply for supplying the whole unit, bottons for operation and a start switch for sending opening and closing signals; besides, a drive circuit is connected with the microcontroller, the output end of the drive circuit is connected with a motor, and the motor is also connected with a sensor for testing the motor running state, the output end of the sensor is connected to the microcontroller. The skylight controlling unit of the vehicle uses double control way of Hawl pulse counting and the current test of the motor to control, hereby is characterized by complete functions, high controlling precision and reliable characteristics, long service life of the motor.

Description

technical field [0001] The invention belongs to the field of electronic technology, and relates to a control device, in particular to an automobile sunroof control device. Background technique [0002] With the continuous development of the automobile industry, all kinds of cars are equipped with automatic sunroofs. The traditional sunroof control system generally uses a mechanical device as the switch limit of the sunroof. The generated overcurrent is used to judge whether the sunroof is in place, that is, the mechanical mechanism that hits the sunroof. The disadvantages of using this control method are: 1. The function is single, the control accuracy is poor, and the failure rate is high; 2. The motor will be blocked every time the window is closed or opened to generate overcurrent, which shortens the service life of the motor. At the same time, the mechanical structure Also be damaged, have reduced the reliability and the service life of skylight; 3, short circuit or ope...

AI Technical Summary

Problems solved by technology

The disadvantages of using this control method are: 1. The function is single, the control accuracy is poor, and the failure rate is high; 2. The motor will be blocked every time the window is closed or opened to generate overcurrent, which shortens the service life of the motor. At the same time, the mechanical structure It is also damaged, which reduces the reliability and service life of the skylight; 3. Short circuit or open circuit is very easy to occur; when a short circuit occurs, it will cause accidents such as burning the motor or damaging mechanical parts
