Embodiment Construction

[0066] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0067] Such as figure 1 Shown, the present invention comprises CAN-LIN gateway, CAN control module and LIN control module three parts, namely:

[0068] -CAN-LIN gateway, connects two physically independent CAN networks or LIN networks, and realizes data exchange between high-speed and low-speed network systems, runs CAN bus protocol and LIN bus protocol, and completes it through CAN control module or LIN control module Distributed control of automotive electronic components, transmit LIN messages to CAN network, where LIN devices work as slave devices, received LIN messages will be transmitted to CAN network, LIN identifiers are converted into CAN identifiers, LIN The data is transmitted through the CAN object; when the CAN-LIN gateway requests transmission, the CAN identifier is converted into a LIN identifier, the data of the CAN object is stored in the bu...

Abstract

The invention consists of CAN-LIN gateway, CAN control module and LIN control module. The CAN-LIN gateway uses CAN bus and LIN bus protocol, and connects to CAN control module through CAM bus interface, and connects to peripherals through peripherals interface to implement signals collection and electronic component control in vehicle. The LIN control module connects to CAN-LIN gateway through LIN bus interface, and connects to peripherals through peripherals interface to implement signals collection and electronic component control in vehicle. The LIN bus protocol is saved in CAN-IN gateway and LIN control module, and the CAN bus protocol is saved in CAN-LIN gateway and CAN control module.

Description

technical field [0001] The invention relates to the field of automobile electronics, in particular to a field bus control system used in the automobile body control system. Background technique [0002] With the improvement of people's requirements for car safety and comfort, the importance of electronic control of the body, including instrument assemblies, lamps, sensors, various switches, doors, rearview mirrors, sunroofs, air conditioners, etc., has become increasingly prominent. More and more cars are being equipped with high-performance automotive body systems. Traditional body electronic control systems often adopt a centralized control scheme, in which a single body electronic control unit is connected to different control targets through a large number of wiring harnesses. However, with the increase in the number and complexity of control targets, the huge wiring harness will take up a lot of space in the car, and will also increase the system cost and reduce the re...
