Problems solved by technology

At present, the automotive CAN / LIN bus application layer specification and effective testing methods and testing instruments for the automotive CAN / LIN bus network are still lacking. The degree of disclosure of the automotive bus CAN technology at home and abroad is very low. It is an agent of foreign products, such as the CANoe tool of the German Vector company, which has a simulation system and a test system for vehicle control, but the cost of such test instruments is very high; the software and hardware system is huge; the usability operation for a specific car body is too complicated; the function can be expanded Poor performance and compatibility; the development cycle of automotive bus nodes is long

Embodiment Construction

[0024] As shown in Figure 1, the overall structure of the monitor is an industrial computer structure, which mainly includes three parts: the monitoring part of the industrial computer, the network transceiver, and the electrical interface of the vehicle. The CAN / LIN network transceiver is responsible for collecting network message information, and sends the information to the industrial computer through a serial bus interface or a USB (Universal Serial Bus, Universal Serial Bus) bus. The monitoring and analysis software architecture of the industrial computer adopts a modular structure, which mainly includes the following modules as shown in Figure 2:

[0025] Main control module: control and call other functional components, read the network data stream from the network transceiver, send data messages, manage data, display message analysis results and analysis results, and complete the storage of corresponding data and the processing of analysis documents;

[0026] Network m...

Abstract

A CAN / LIN network detector of vehicle control system is prepared as using industrial control computer to form detector, connecting CAN / LIN network transceiver to vehicle electric interface for collecting network message information and sending it to industrial control computer through serial bus interface or USB interface; applying modularization structure on industrial control computer to analyze node working efficiency, network node state, network load state and so on in real time accurately.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to a network control system for an automotive electronic vehicle body. Background technique [0002] It is the development trend of automobile electronic technology to control the automobile through the automobile bus. The automotive bus network is applied to the control system, information system, driving system and sensor execution system of the vehicle to complete the communication and action of various sensors, controllers and actuators of the vehicle, and realize the distributed control of the vehicle electronic control system . At present, the automotive CAN / LIN bus application layer specification and effective testing methods and testing instruments for the automotive CAN / LIN bus network are still lacking. The degree of disclosure of the automotive bus CAN technology at home and abroad is very low. It is an agent of foreign products, such as the CANoe tool of the Germa...
