In this embodiment, the method for testing the automobile diagnostic apparatus includes the following steps:
Step S10: and when a diagnostic instrument test instruction of the automobile is received, acquiring an open type diagnostic data file.
It should be noted that, the execution body of the embodiment is the automobile diagnostic apparatus testing device, where the automobile diagnostic apparatus testing device may be an electronic device such as a personal computer or a server, or may be other devices that may implement the same or similar functions, and the embodiment is not limited thereto. In this embodiment, the automotive diagnostic apparatus test device has an open diagnostic data (Open diagnostic data exchange, ODX) parsing function, that is, the automotive diagnostic apparatus test device may receive an open diagnostic data file (ODX file) imported by a diagnostic engineer.
Specifically, ODX files are mainly written in extensible markup language (Extensible Markup Language, XML). XML is widely used in the field of data exchange because of its high flexibility and expandability to ensure the uniformity of data. The open diagnostic data file of the open diagnostic data of the road vehicle is a vehicle data diagnostic file based on XML format, and the open diagnostic data file may be used to describe data related to an electronic control unit (Electronic Control Unit, ECU) of the automobile. The open diagnostic data file may include ECU-related information such as control primitives, data communication primitives, communication parameters, vehicle information, and configuration specifications between the vehicle and the ECU. The automobile diagnostic instrument test equipment comprises an automobile diagnostic instrument test system, wherein the automobile diagnostic instrument test system is an automobile diagnostic system based on an ODX database architecture, and all information related to each ECU can be obtained by reading and analyzing the ODX file of the ECU, so that the requirements of diagnostic data of each stage are met.

The test parameters of the forward diagnostic apparatus may further include other parameters, which are not limited in this embodiment.
Specifically, in this embodiment, the forward tests of two protocols, i.e., ISO14229 and ISO15031, are used to support the functions of fault code reading, freeze frame data reading, extended frame data reading, data parameter reading, dynamic definition parameter reading, periodic data reading, data parameter writing, controller reset, communication control, DTC control setting, IO control test, etc. in the ISO14229 protocol; routine control, PID reading, fault code reading, freeze frame reading, test execution, vehicle information reading, and the like can be supported in the ISO15031 protocol.

It should be understood that the reverse test item refers to performing a reverse test on the diagnostic apparatus, and may send an error response to the diagnostic apparatus according to a configuration of a user, where the reverse test may support: negative response, error response, transmission layer message time sequence error, timing parameter overtime test and other functions. When the diagnostic instrument test item is a reverse test item, a diagnostic test case of the reverse test item can be generated according to the fault code, the frozen frame data, the data parameters, the write data parameters, the controller reset, the communication control parameters, the diagnostic fault code and the input/output test parameters.

When the diagnostic apparatus test item is a reverse test item, the embodiment uses a reverse test for reading a fault code as an example to explain: acquiring a fault code according to the diagnosis test case, and determining a corresponding negative response parameter according to the fault code; when a reverse diagnosis request instruction sent by a diagnostic instrument is received, sending the fault code to the diagnostic instrument according to the negative response parameter; when the diagnostic instrument receives the fault code, acquiring display data of the diagnostic instrument, and judging whether the display data are negative response display data or not to obtain a judging result; and determining a test result according to the judgment result.
Specifically, the reverse test is performed on the services of the diagnostic apparatus, such as fault reading, freezing frame reading, data reading parameter, data writing parameter, controller resetting, communication control, DTC control, IO control, and the like, so that negative response parameters are set in a simulation manner in an automobile diagnostic apparatus test system of automobile diagnostic apparatus test equipment, and whether the diagnostic apparatus can correctly respond to the controller to reply negative response can be judged by judging whether the diagnostic apparatus can correctly display the set negative response parameters. After the reverse test is started, the diagnostic instrument is operated to send a diagnostic instruction to the test software, and the test software replies negative response parameters to the diagnostic instrument according to the set negative response. If the diagnostic instrument correctly displays the set negative response parameters, the reverse test is qualified.

And after the functional tests such as the forward test and the reverse test are carried out, test results are obtained, and a diagnostic instrument test report is generated and displayed.
Specifically, after the forward test is started, the operation diagnostic instrument sends a fault code requesting instruction to the automobile diagnostic instrument test system, and at the moment, the test software replies a fault code to the diagnostic instrument according to the set positive response. If the diagnostic instrument correctly displays the set fault code, the test result is that the fault reading function is qualified, and a diagnostic instrument test report that the fault reading function is qualified is generated and displayed.
Specifically, after the reverse test is started, the diagnostic instrument is operated to send a diagnostic instruction to the test software, and the test software replies negative response parameters to the diagnostic instrument according to the set negative response. If the diagnostic instrument correctly displays the set negative response parameters, the test result is that the reverse test is qualified, and a diagnostic instrument test report that the reverse test is qualified is generated and displayed.
