Abstract

The invention discloses a car lamp control system based on a CAN-LIN network. The system comprises a key module, a host module and multiple slave machine modules, wherein the key module is connected to a CAN bus and used to input switch signals; the key module is connected to the CAN bus and an LIN bus, and the host module receives a CAN data frame composed of the switch signals by the CAN bus, analyzes and processes the CAN data frame, composes an LIN data frame and sends the LIN data frame by the LIN bus; and each slave machine module comprises LIN slave machine nodes which conduct communications with the host module as well as a drive control module which controls a car lamp, and the slave machine module receives the LIN data frame from the LIN bas so as to control the car lamp. According to the invention, communications in the CAN-LIN network have the advantages of simple hardware circuits, clear control levels and the low cost, etc.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a CAN-LIN network-based vehicle light control system. Background technique [0002] Automotive electronics is the general term for car body electronic control devices and vehicle electronic control devices. Automobile electrification is considered to be a revolution in the development of automobile technology and the most important technical measure to improve automobile performance. In recent years, with the rapid development of information technology and the continuous improvement of the automobile manufacturing industry, the proportion of electronic equipment in the total cost of automobiles has also increased. According to statistics, from 1970 to 2014, the global automotive electronic equipment The cost ratio has risen from 2% to over 50%. In the past 10 years, 70% of the innovations in the automotive industry have come from the development and application o...
