Embodiment Construction

[0038] In this patent, the CAPL code is automatically generated, and only CANoe or CANalyzer is used to perform related tests on the CAN bus of the electronic control unit. The specific implementation will be further described below in conjunction with the accompanying drawings and examples.

[0039] Such as figure 1 As shown, the embodiment of the present invention provides CAPL code automatic generation method, and described method comprises:

[0040] Step S11, acquiring the DBC file of the communication matrix.

[0041] Specifically, step S11 includes:

[0042] Run MATLAB software, edit M script;

[0043] Read the DBC file of the communication matrix in text format.

[0044] Step S12, extract the key information of each CAN bus in the DBC file, the key information includes CAN message size, address, sending cycle, sending type, CAN message name, description, start bit, signal length, maximum value, At least one of minimum value, initial value, precision, offset, signal ...

Abstract

The invention provides a CAPL code automatic generation method and system and an automobile. The method comprises the steps that a DBC file of a communication matrix is acquired; key information of each CAN bus in the DBC file is extracted; based on the key information of each CAN bus, an independent CAPL language code file is automatically generated, and the CAPL language code file comprises a message signal analysis function, a message verification function, a message counting function, a simulation message stop function, a simulation frame loss function, a simulation message verification error function and a simulation message counting error function; the method also includes operating CANoe software or CANalyzer software, connecting any hardware equipment in the CANoe software or the CANalyzer software, and importing a DBC file to a CAN channel of any hardware equipment in a Database Management environment; inserting a programming node in a Measurement Setup environment, importing a CAPL language code file, and compiling the CAPL language code file; and connecting the CAN bus channel of the electronic control unit with the CAN channel of any device. According to the invention, the problems that the manual configuration of the existing CAN tool is tedious and the Dspace rack is inconvenient to carry are solved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a CAPL code automatic generation method, system and automobile. Background technique [0002] Existing CAN tools or test equipment need to be cumbersomely configured after being imported into DBC, which is very inefficient and prone to configuration errors, which will affect the correctness of the test results of the electronic control unit and affect the efficiency of software development; even if a bench like Dspace can Perform a variety of custom configurations, but it is not portable and cannot support out-of-home testing and debugging. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a CAPL code automatic generation method, system and automobile, which are used to solve the problems of cumbersome manual configuration of existing CAN tools and inconvenient portability of the Dspace stand. [0004] A kind of CA...
