Problems solved by technology

[0006] At present, for most models on the market and private protocol frameworks such as ISO-14229 (also known as UDS (Unified Diagnostic Services, Unified Diagnostic Services), the CAN bus network data is directly monitored. The amount of data is too large, and the vehicle-mounted equipment and the vehicle-mounted ECU broadcast data in the same CAN network, so it is difficult to distinguish which data is sent by the vehicle-mounted ECU and which is sent by the vehicle-mounted device
In addition, in monitoring the CAN bus network, the data sent by the vehicle ECU will continue to change based on vehicle status and environmental factors, and it is difficult to analyze some difficult data through binocular and long-term data records
[0007] Therefore, the processing method of CAN data in the CAN bus of the prior art is unfavorable for data analysis, and the efficiency is also low

Abstract

The invention discloses a dual CAN channel data processing method and system, and a gateway device. The dual CAN channel data processing method comprises the steps of acquiring data of different CAN networks through different CAN channels, wherein a vehicle-mounted ECU and a vehicle-mounted CAN bus product are located in the different CAN networks; and under the condition that a preset forwardingcondition is met, setting an identifier for the data of one CAN network and then forwarding the data to another CAN network. According to the scheme, data analysis can be carried out on a vehicle CANbus more conveniently, and the processing efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of Internet of Vehicles, in particular to a dual CAN channel data processing method, gateway device and system. Background technique [0002] With the continuous development of modern automobile technology, the CAN (Controller Area Network, Controller Area Network) bus has gradually become an indispensable technology in modern automobiles, and has greatly promoted the rapid development of automobile technology. [0003] The CAN bus was first developed by the German Bosch (Bosch) company to solve the data exchange between numerous ECUs (Electronic Control Unit, electronic control unit, also known as "driving computer", "vehicle computer", etc.) in modern automobiles. communication protocol. The CAN bus connects each single control unit in some form (mostly in a star shape) to form a complete system. In this system, each control unit performs data transmission exchange and sharing with the same rules, which ...
