Problems solved by technology

However, there is no practical application in automotive lighting element control systems
[0003] If the indicator light is damaged while the car is driving, there will be unsafe hazards such as car collision
For example, when a car is turning, whether the front or rear turn signals are damaged, it is difficult to indicate the steering requirements to the adjacent drivers; when driving at night, if the width indicator lights are damaged, it is difficult to indicate to the adjacent drivers; In the process of driving, if the brake light of the car is damaged, it is easy to cause traffic accidents such as rear-end collision
The existing automotive lighting component control system has no corresponding emergency treatment measures, and can only be used again after the car is repaired

Abstract

The invention discloses a system and method for controlling automotive lighting elements based on CAN (controller area network) data transmission. The system comprises a main control system, a CAN bus and a node lighting control system, wherein the node lighting control system is connected with the main control system by the CAN bus; the main control system sends a command to the node lighting control system, and receives feedback information of the node lighting control system; and the node lighting control system receives the command of the main control system, and sends the feedback information to the main control system so as to automatically replace the damaged lighting elements. The system and method disclosed by the invention can be used for detecting the states of the automotive lighting elements, prompting on damaged lighting elements and replacing the damaged lighting elements, thereby reducing the potential safety hazards of automobiles in the process of driving, and improving the safety of automotive lighting.

Description

technical field [0001] The invention relates to a control system and a control method of an automobile lighting element based on CAN data transmission. Background technique [0002] CAN (ControllerAreaNetwork) data bus is an automotive local area network suitable for automotive environments. It belongs to one of the multiplex transmission systems, a serial communication developed by the German Bosch company in the early 1980s to solve the data exchange between numerous control units and test instruments in modern automobiles protocol. Because it has the characteristics of fully distributed multi-machine system, multiple communications, high transmission reliability, strong security, no network failure, easy expansion and easy implementation, it is widely used in automobiles. However, it has no practical application in automotive lighting element control systems. [0003] If the indicator light is damaged during the driving of the car, there will be unsafe hidden dangers s...
