Problems solved by technology

It can be seen from the above-mentioned traditional code-reading card opening method that it still needs repeated modification and verification, which is not only time-consuming, labor-intensive, and inefficient, but also has the disadvantage of not being able to fully test all states of the OBD code-reading card.

Abstract

The invention provides a method for analog simulation development of an automobile OBD (On-Board Diagnostics) code reading card, which comprises the following steps of: 1. confirming the function layout of an OBD code reading card according to a test function demand needing to be realized and further confirming the hardware composition of the OBD code reading card; 2. providing a computer and analog parts corresponding to the all hardware of the OBD code reading card in the computer according to the function layout of the OBD code reading card; 3. combining all the analog parts corresponding to all hardware of the OBD code reading card in the computer to form a code reading card analog simulation platform capable of analog running; 4. carrying out analog development on the code reading card analog simulation platform and compiling a code according to the test function demand needing to be realized for realizing the test function; and 5. replacing the compiled code in the analog parts into a drive code run on practical code reading card equipment and compiling and downloading to the OBD code reading card for carrying out communication actual measurement with an automobile ECU (Electronic Control Unit). The invention comprehensively simulates the code reading card analog simulation platform, can ensure that a code developer carry out code reading card development under the condition of separating practical code reading card equipment and prevent repeated code downloading and actual measurement verification, and improves the development efficiency.

Description

technical field [0001] The invention relates to a development method of a code-reading card for an on-board automatic diagnosis system (OBD: On-Board Diagnostics), in particular to a method for realizing the development of an OBD code-reading card using software simulation and simulation. Background technique [0002] In 1994, the American Society of Automotive Engineers (SAE) proposed the standard specification of the second generation on-board self-diagnosis system (OBD-II). Read out the data in and present the information represented by these data to the user. OBD-II has made unified regulations in many aspects such as software protocol, hardware interface, physical size, fault code, and data flow definition of automobile self-diagnosis. But at the same time, OBD-II protocol communication types also have different physical connections, and different car manufacturers can also have some customized applications in application. With the continuous development and improveme...
