Automobile CAN bus debugging system based on wireless communication

Abstract

The invention discloses an automobile CAN bus debugging system based on wireless communication. The automobile CAN bus debugging system comprises more than three debugging terminals, a CAN-to-WIFI communication module, and an automobile bus diagnosis interface. The more than three debugging terminals share one wireless communication module, all the debugging terminals are connected to an automobile bus diagnosis interface through the wireless communication module, and all the debugging terminals can work in a mutual coordination manner, receive and send data and monitor and debug an automobilein real time. The system has the following advantages that remote data real-time monitoring can be realized aiming at debugging work in an automobile design and research and development stage, debugging personnel do not need to be limited on a vehicle, the maneuverability of the personnel is improved, a tedious wiring mode is avoided, and the problem of working space limitation is solved. The system can be connected to a plurality of local and remote debugging terminals at the same time, and the efficiency and coordination of on-site debugging work are improved.

Description

technical field [0001] The invention relates to the field of vehicle-mounted systems, in particular to a remote data real-time debugging and monitoring system based on a wireless communication CAN bus for the debugging work in the design and development stage of automobiles. Background technique [0002] CAN is the abbreviation of Controller Area Network (CAN). It was developed by German BOSCH company, which is famous for R&D and production of automotive electronic products, and eventually became an international standard (ISO 11898). It is the most widely used in the world. One of the fieldbus. CAN bus connects each single control unit to form a complete system. In this system, each control unit performs data transmission, exchange and sharing with the same rules. In automotive engineering, with more and more automotive electrical equipment, from power system control to body system control, from driving, braking, steering system control to safety assurance system and inst...

AI Technical Summary

Problems solved by technology

[0003] In the on-site debugging of automobile CAN bus, it is generally used to connect to the bus in a wired way, and connect to a laptop computer for data reception and transmission. In the on-site debugging, each control unit needs to coordinate and work, and usually needs to be connected to more than three monitoring terminals. Wired connection The access method has problems such as cumbersome wiring and limited work space, which makes it difficult to coordinate the work of each control unit on site during debugging and affects work efficiency; and the wired access method limits the data exchange between the on-site vehicle and the remote debugging terminal
