Embodiment Construction

[0018] The present invention "an automobile lamp control system based on LIN network" consists of CAN bus, LIN bus, 1 master node (CAN-LIN gateway), 4 slave nodes (respectively left front, left rear, right front, right rear 4 A car light node at the corresponding position), CAN transceiver line and 5 LIN transceivers, among which 4 slave nodes are connected to the LIN bus through 4 LIN transceivers; the master node is connected to the LIN bus through another LIN transceiver, It is connected to the CAN bus through the CAN transceiver line. The steps of the system to control the lights are as follows:

[0019] (1) The master node sends the interval field, synchronization field, and identifier field in turn, calls the LINSendMsg() function to send the header, performs identifier matching, and sends the light switch information to each slave node in a package;

[0020] (2) The slave node that receives the header sends a response frame, receives the switch information sent by the m...

Abstract

The invention designs an automobile lamp control system based on an LIN (Local Interconnect Network) bus. The automobile lamp control system consists of a CAN (Controller Area Network) bus, an LIN bus, a main node (CAN-LIN gateway), four slave nodes (front-left, back-left, front-right and back-right automobile lamp nodes), a CAN receiving-transmitting wire and five LIN transceivers, so that real-time accurate control on an automobile lamp can be realized, the wiring complexity degree inside an automobile is lowered, and the reliability and intelligence of the automobile lamp control system are improved.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, especially the field of automobile lamp manufacturing. Background technique [0002] In recent years, my country's automobile industry has developed rapidly. The development direction of modern automobiles tends to be more electronic, intelligent, and networked. In this case, electronic control units and sensors are more widely used in automobiles, which has brought a substantial increase in automobile wiring harnesses. More and more electronic control units and sensors make the traditional wiring methods no longer meet the needs. [0003] The LIN (Local Interconnect Network) bus protocol is a serial communication protocol based on a general-purpose SCI / UART hardware interface, which can connect smart sensors and actuators distributed in different positions of the vehicle to the vehicle network to form a single bus , Locally interconnected communication network. As an auxiliary network...
