Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] A method for generating a CAN general message database, comprising:

[0025] Step 1, obtain CAN message attributes;

[0026] The method for obtaining CAN message attributes includes: obtaining a CAN communication network matrix form, obtaining a stored message attribute format and a corresponding message database template according to a standard protocol.

[0027] The standard protocol includes the standard protocol acquisition and storage message attribute format, and the corresponding message database template.

[0028] Step 2, input the CAN message attributes into the attribute table, and extract the data information of the message in the table; it also includes the step of analyzing the message attribute data information, and divides the message attribute data information analysis into three categories: the first category is CAN Network nod...

Abstract

The invention discloses a CAN general message database generation method. The method comprises the following steps: acquiring a CAN message attribute; inputting the CAN message attribute into an attribute table, and extracting the data information of the message in the table; storing the message attribute data information, and performing attribute error checking; and packaging the message attribute data information, and generating a message database according to a standard protocol. According to the method, the definition of the CAN message communication matrix table document is standard, most attribute values are included, high flexibility is also provided in editing, and meanwhile, the randomness of attribute input is also limited. The tool is easy to operate, errors are easy to check, the dbc file is directly generated, and high efficiency and accuracy are achieved.

Description

technical field [0001] The invention belongs to the technical field of vehicle controller development software, and in particular relates to a CAN general message generation tool and method. Background technique [0002] In the development of the vehicle CAN network, different CAN messages and nodes need to be defined according to different network topology diagrams. Since different nodes have different requirements for sending and receiving messages, a variety of message configurations are required during the development of the message software, and usually the vehicle CAN network has a large number of messages, so the work of creating a new message database in DBC Editor It is cumbersome, time-consuming and has a high error rate. Invention content: [0003] In order to overcome the defects of the above-mentioned background technology, the present invention provides a method for generating a CAN general-purpose message database. The tool in the embodiment of the present ...
