DETAILED DESCRIPTION

In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

According to an embodiment of the present invention, a method embodiment for automatically generating a diagnostic application data packet is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

In this embodiment, a method for automatically generating a diagnostic application data packet is provided, which can be used in a controller. FIG. 1 is a flow chart of the method for automatically generating a diagnostic application data packet according to an embodiment of the present invention. As shown in FIG. 1 , the process includes the following steps:

Step S101, obtaining diagnostic requirement data.

Specifically, the diagnostic demand data includes the customer demand data involved in the unified diagnostic service UDS. The diagnostic demand data can be the internal data of the automotive electronic control unit (Electronic Control Unit, referred to as ECU) requested by the diagnostic device, specifically including: current data: data that the ECU is running, such as vehicle speed, throttle opening, engine speed, etc.; stored data: data stored in the memory by the ECU at a certain moment, such as DTC (Diagnostic Trouble Code); static data: constant ECU internal data, such as VIN code (Vehicle Identification Number). When the customer has the need to diagnose the automotive system, the diagnostic demand data provided by the customer is obtained.

For example, the diagnostic requirement data may be a diagnostic and communication control function group, including a diagnostic service ID and a service name of a diagnostic service, where the service name is the specific content of the service. The diagnostic service ID refers to a diagnostic service identifier.

Step S102, filling the diagnosis requirement data into a preset diagnosis file template.

Specifically, the preset diagnostic file template can be set as an Excel table, and a unified corresponding header format is set for each diagnostic requirement data. When a difference data packet needs to be generated, the diagnostic service ID in the diagnostic requirement data and the specific content of the diagnostic service corresponding to the diagnostic service ID need to be filled in the preset diagnostic file template. The specific content of the diagnostic service can be electronic control unit reset diagnosis, diagnostic session control, security access diagnosis, communication control diagnosis, etc.

Step S103, generating a differential data packet with a uniform format according to the diagnostic requirement data in the diagnostic file template. Specifically, the differential data packet is a data packet generated for the specific content in the customer's diagnostic requirement data. When the diagnostic requirement data is filled in the diagnostic file template, a diagnostic tool can be used to generate a differential data packet with a uniform format for the specific content in the diagnostic requirement data.

For example, the electronic control unit reset diagnosis, diagnostic session control, security access diagnosis, and communication control diagnosis in the specific content of the diagnostic service may be generated into a differential data packet with a unified format.

Step S104, combining the difference data packet and the preset common data packet to form a diagnostic application data packet. Specifically, the preset common data packet can be a data packet with a unified diagnostic function generated according to the diagnostic standard. The diagnostic application data packet is composed of the difference data packet and the preset common data packet. After the difference data packet is generated, it can be directly superimposed with the common data packet to form a diagnostic application data packet.

The method for automatically generating a diagnostic application data packet provided by the present invention fills the diagnostic requirement data into a preset diagnostic file template, generates a differential data packet in a uniform format according to the diagnostic requirement data in the diagnostic file template, thereby realizing one-time generation of differential data packets for a large amount of customer diagnostic requirement data, and combining the differential data packet with the preset general data packet to form a diagnostic application data packet. The generated diagnostic application data packet has high efficiency and high accuracy, and solves the problem of low efficiency in generating diagnostic data packets when the customer provides a large amount of diagnostic data and the requirement is urgent.

In this embodiment, a method for automatically generating a diagnostic application data packet is provided, which can be used in the above-mentioned controller. FIG. 2 is a flow chart of the method for automatically generating a diagnostic application data packet according to an embodiment of the present invention. As shown in FIG. 2 , the process includes the following steps:

Step S201, obtaining diagnostic demand data. Specifically, the diagnostic demand data includes: any one or more of diagnostic and communication control function group data, data transmission function group data, input and output control data, and routine control data. The diagnostic and communication control function group data, data transmission function group data, input and output control data, and routine control data all include: a diagnostic service ID and a service name corresponding to the diagnostic service ID, where the service name is the specific content of the service.

The diagnostic and communication control function group data includes six sub-functions, namely diagnostic service ID10 and the corresponding diagnostic session control diagnosis, diagnostic service ID11 and the corresponding electronic control unit reset diagnosis, diagnostic service ID27 and the corresponding security access diagnosis, diagnostic service ID28 and the corresponding communication control diagnosis, diagnostic service ID14 and the corresponding clearing of diagnostic information, and diagnostic service ID19 and the corresponding reading of fault code information.

Step S2022, fill in the preset diagnostic file template with the diagnostic service ID, the service name corresponding to the diagnostic service ID, the sub-function ID' corresponding to the diagnostic service ID, the sub-function service name corresponding to the sub-function ID', the prohibition/affirmative response bit, physical addressing, functional addressing, supported negative response codes and explanatory notes in the diagnostic requirement data.

For example, when the diagnostic requirement data belongs to the diagnostic and communication control function group diagnostic category, the diagnostic requirement data is filled into the preset diagnostic file template as shown in Table 2 below:

Table 2

In Table 2, Y indicates that the ECU supports it, N indicates that the ECU does not support it, and N/A indicates that the service does not contain sub-functions.

Step S203: Generate a difference data packet with a unified format according to the diagnosis requirement data in the diagnosis file template. Please refer to step S103 of the embodiment shown in FIG1 for details, which will not be repeated here.

Step S204: Combining the difference data packet and the preset common data packet to form a diagnostic application data packet. For details, please refer to step S104 of the embodiment shown in FIG1 , which will not be described in detail here.

Step S303, generating a difference data packet with a unified format according to the diagnosis requirement data in the diagnosis file template. The unified format includes unified data format, unified character space occupied by data and unified data arrangement.

Specifically, the above step S303 includes:

Step S3031, using a diagnostic tool to parse the diagnostic requirement data in the diagnostic file template to generate parsed data. Specifically, the diagnostic tool can be implemented in Python language, using Python language to parse the diagnostic requirement data in the diagnostic file template, obtain the specific data of each diagnostic service of the diagnostic and communication control function group data, data transmission function group data, input and output control data and routine control data, and generate a diagnostic code as parsed data.

Step S3032, generating a difference data packet with a unified data format, unified data occupied character space, and unified data arrangement based on the parsed data.

Specifically, a diagnostic tool is used to generate differential data packets with unified data format, unified data occupied character space and unified data arrangement for the diagnostic codes of specific data of each diagnostic service, including diagnostic and communication control function group data, data transmission function group data, input and output control data and routine control data.

Step S304, combining the difference data packet and the preset common data packet to form a diagnostic application data packet. Specifically, the preset common data packet is a common data packet generated according to the diagnostic standard and having the same format as the difference data packet. The diagnostic standard is the UDS automotive diagnostic standard protocol ISO 14229-1. According to the UDS automotive diagnostic standard protocol ISO 14229-1, a diagnostic service with unified functions is generated into a common data packet in the same format as the difference data packet. After the difference data packet is generated, the difference data packet and the preset common data packet are superimposed to form a complete diagnostic application data packet.

The method for automatically generating a diagnostic application data packet provided by the present invention uses a diagnostic tool to parse the diagnostic requirement data in the diagnostic file template to generate parsed data; based on the parsed data, a difference data packet with a unified data format, uniform data occupied character space, and uniform data arrangement is generated, so that the data of the difference data packet is neat, high in accuracy, and easy to calibrate; the diagnostic tool is used to generate parsed data, and finally a difference data packet is generated, and code writing is not performed by manually comparing the diagnostic data, thereby avoiding the problem of easy errors in the process of generating a data packet for each diagnostic requirement data in sequence, and improving the efficiency and accuracy of generating the difference data packet. The diagnostic data packet is separated by universality and difference, so that the diagnostic framework is concise and clear, easy to maintain, and the data format and function of the constructed diagnostic application data packet are complete, and the data accuracy is high.

As one or more specific application embodiments of the embodiments of the present invention, as shown in FIG4 , the method for automatically generating a diagnostic application data packet can be implemented using the following process:

Step S401, obtaining diagnostic requirement data provided by the customer.

Specifically, the diagnostic demand data includes the customer demand data involved in the unified diagnostic service UDS. The diagnostic demand data can be the internal data of the automotive electronic control unit (Electronic Control Unit, referred to as ECU) requested by the diagnostic device, specifically including: current data: data that the ECU is running, such as vehicle speed, throttle opening, engine speed, etc.; stored data: data stored in the memory by the ECU at a certain moment, such as DTC (Diagnostic Trouble Code); static data: constant ECU internal data, such as VIN code (Vehicle Identification Number). When the customer has the need to diagnose the automotive system, the diagnostic demand data provided by the customer is obtained.

For example, the diagnostic requirement data may be a diagnostic and communication control function group, including a diagnostic service ID and a service name of a diagnostic service, where the service name is the specific content of the service. The diagnostic service ID refers to a diagnostic service identifier.

The diagnostic and communication control function group data includes six sub-functions, namely diagnostic service ID10 and the corresponding diagnostic session control diagnosis, diagnostic service ID11 and the corresponding electronic control unit reset diagnosis, diagnostic service ID27 and the corresponding security access diagnosis, diagnostic service ID28 and the corresponding communication control diagnosis, diagnostic service ID14 and the corresponding clearing of diagnostic information, and diagnostic service ID19 and the corresponding reading of fault code information.

Step S406, combining the difference data packet and the preset common data packet to form a diagnostic application data packet.
