Vehicle dormer window movement control system and method

Abstract

The invention provides a system for controlling the motion of an automobile skylight. The system can flexibly execute a bodywork control program and has a simple structure; the system comprises a control module, a current sampling module, a sensing signal acquisition module, a switch signal acquisition module, a motor drive module and a clock pulse generation module, wherein the current sampling module acquires the current information of a motor of the automobile skylight and inputs the information to the control module; the sensing signal acquisition module acquires a sensing signal of the operating state of the motor of the automobile skylight and inputs the signal to the control module; the switch signal acquisition module acquires each control switch signal and inputs the signal to the control module; the motor drive module receives a control module instruction and drives the motor of the automobile skylight to operate; and the clock pulse generation module generates a clock pulse signal and inputs the signal to the control module. In the method, the control module sequentially schedules each module or sub-unit and executes corresponding operation in each system cycle.

Description

technical field [0001] The invention relates to the technical field of automobile body control, in particular to an automobile skylight motion control system and a control method. Background technique [0002] The car sunroof control system is a key component in the car sunroof control assembly, and its performance directly affects the performance of the entire sunroof control assembly, such as a car sunroof disclosed in the Chinese invention patent application publication with the publication number CN101214786A The control device is connected to the driving circuit on the microcontroller, the output end of the driving circuit is connected to the motor, the motor is also connected to a sensor for detecting the running state of the electrode, and the output end of the sensor is connected to the microcontroller; and For example, the electric sunroof controller with parameter correction disclosed in the Chinese Invention Patent Application Publication No. CN101256395A can regu...

AI Technical Summary

Problems solved by technology

However, because the single-chip microcomputer program can only be executed sequentially and lacks flexibility, interrupt functions can only be used to process some shorter tasks in real time. In the automotive sunroof motion control system, it is necessary to collect various status data of the sunroof motor. And control such as anti-clamping, the traditional single-chip microcomputer has a large amount of program code, complex structure, high hardware requirements, and difficult development

[0004] In addition, these existing sunroof control systems are all independent control systems and cannot communicate with other control systems of the body, such as the existing BCM (Body Control Module), RKE (Remote Keyless Entry), etc. , which is not conducive to the integration of automatic control of the whole vehicle. At the same time, because the existing sunroof control system does not have a bus communication module, it also brings difficulties to the fault diagnosis of the sunroof control system
