Abstract

The invention provides a controller local area network network control system and a detection and debugging method thereof. The controller local area network network control system includes: a controller local area network bus for transmitting messages; a plurality of electronic control devices respectively having running programs; a detector with all running programs of each of the multiple electric control devices; a controller local area network bus an interface unit for physically coupling the controller area network bus with the detector. Due to the controller LAN network control system and its detection and debugging method, by using the controller LAN bus to confirm whether each electric control device is working normally, and at the same time, it is possible to correct the operating program of the wrongly running electric control device, thereby significantly improving Reduce the time and expense required to debug incorrectly functioning electronic controls.

Description

technical field [0001] The invention relates to a controller area network network control system, in particular to a controller area network network control system for comprehensive management of electronic devices in vehicles adopting a controller area network (CAN: controller area network) protocol and a detection and debugging method thereof. Background technique [0002] The controller area network was originally proposed as a serial network communication method for the application in the automotive industry. At present, it is widely used in all industrial fields besides the automotive field. The basic controller area network network system structure used in the automotive field is as follows: figure 1 shown. Such as figure 1 As shown, the controller area network network system has a plurality of nodes (node), and is provided with a controller area network bus 1 for transmitting various messages, a plurality of electronic control devices (ECU-Electronic Control Unit) 2...
