Detailed Description

To make the objects, technical solutions and advantages of the present application clearer, the present application will be described in further detail with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It should be noted that references in the specification of the present application to the terms "comprises" and "comprising," and variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Some of the words that appear in the text are explained below:

(1) AUTOSAR (automatic Open System Architecture, Open systems Architecture for automobiles): the automotive open system is a cooperative development framework of an automobile electronic system, which is commonly participated by automobile manufacturers, part suppliers and various research and service organizations all over the world, and establishes an open automobile controller (ECU) standard software architecture. Typically, each OEM (Original Equipment Manufacturer) will produce more than one vehicle model, each OEM will select more than one supplier for different subsystems and components, and each supplier will supply more than one OEM. The most effective way to reduce the development cost is to make the product reusable as much as possible, and to share the development cost by quantity. OEMs desire to have the same set of systems and components available on different vehicle models; systems and components from different suppliers on the same vehicle may be compatible with each other; and the components and algorithms that the supplier wishes to develop may be supplied to different OEMs with simple software adjustments. On the other hand, the development schedules of the various suppliers are often not synchronized. It is desirable to test whether the component is properly mated with other systems on the vehicle during the development process by the supplier. There is therefore a need for a unified, standardized system description method. This is the primary goal of automotive systems, namely to improve management of complex automotive electronics and electrical architectures by improving the reusability and interchangeability of software modules between OEMs and vendors. Thus, AUTOSAR is mainly to implement: standardizing interfaces between the application software and the bottom layer software and between the application software; giving a controller software reference architecture; exchange formats in the distributed development process are specified.

(2) ARXML (Architecture eXtensible Markup Language) file: the ARXML file is used as a general configuration file or a database file under the AUTOSAR framework, and plays a key role in data transmission and storage. XML (eXtensible Markup Language) is a Markup Language similar to HTML, which is designed to transmit data rather than display data, and has self-descriptive property, and its tags are not predefined and need to be self-defined. On the basis of an XML file, the AUTOSAR specification defines the file format of the transmission information as ARXML based on the application scene of automobile electronics.

(3) A data dictionary: the data dictionary is used for defining and describing data items, data structures and the like of data, and aims to make detailed description on each element in the data flow chart, and the data dictionary is used as a simple modeling item. In short, a data dictionary is a collection of information describing data, a collection of definitions for all data elements used in a system.

In the field of automatic driving, the mainstream way of the Automotive Open System Architecture (AUTOSAR) software development process is to automatically generate an ARXML file required by Architecture software through the existing Simulink control model. The automotive industry is mature and many tested models can be reused on different platforms without any manual modification of the model, such as automotive architecture.

In the development of AUTOSAR automatic driving software in the related technology, a data dictionary of AUTOSAR standard cannot be generated independently, an automatic driving algorithm model, a model data dictionary, an algorithm dependency library and the like need to be loaded into Matlab software, model conversion is carried out through an AUTOSAR standard tool, then automatic code generation is carried out, and a generated ARXML file contains all description information of the automatic driving software, so that the process is complex, the consumed time is long, and the efficiency is low when the data dictionary of the AUTOSAR standard is generated.

In order to solve the above problem, an embodiment of the present application provides a data dictionary processing method, which includes obtaining a target dictionary entry included in a to-be-processed data dictionary based on an identifier of the to-be-processed data dictionary that does not meet an AUTOSAR standard, then packaging the target dictionary entry based on a DDS specification, generating a message structure corresponding to the target dictionary entry, and storing the message structure in a preset target communication carrier, where the message structure includes data structure information of the target dictionary entry, and then obtaining data structure information in the message structure from the target communication carrier in response to receiving a format conversion instruction, and performing code conversion on the obtained data structure information to obtain a target data dictionary that meets the AUTOSAR standard. According to the method, the data dictionary which meets the AUTOSAR standard is generated only through the data dictionary which does not meet the AUTOSAR standard, and an automatic driving model and an algorithm dependency library do not need to be loaded, so that the data dictionary which meets the AUTOSAR standard can be generated more conveniently, the labor cost for generating the data dictionary which meets the AUTOSAR standard can be saved, and the generation efficiency of the data dictionary which meets the AUTOSAR standard can be improved.

The technical solutions provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Fig. 1 shows a flowchart of data dictionary processing provided in an embodiment of the present application. As shown in fig. 1, the method may include the steps of:

step S101, based on the identification of the data dictionary to be processed, obtaining the target dictionary entry included in the data dictionary to be processed.

Wherein, the data dictionary to be processed does not conform to AUTOSAR standard.

The file conforming to the AUTOSAR standard needs to be an ARXML file. In the embodiment of the application, the to-be-processed data dictionary is a data dictionary in a Sldd format created by MATLAB, and does not conform to the AUTOSAR standard.

The target dictionary entry may be a partial or complete dictionary entry in the pending data dictionary.

Illustratively, the identifier of the to-be-processed data dictionary Deal _1 is DOC _ ModelINOUT, and the file format is Sldd format. The pending data dictionary Deal _1 is shown in table 1.

TABLE 1

Data item	Data type	…
			Gaspedal	single	…
Mastercylind	single	…
			DrvSBR	boolean	…
PassSBR	boolean	…

As can be seen from table 1, it is assumed that the pending data dictionary Deal _1 includes 4 target dictionary entries, and the data items of the 4 target dictionary entries are Gaspedal, Mastercylind, drvbsbr and PassSBR, respectively. The file format of the data dictionary Deal _1 to be processed is in a Sldd format, and does not accord with AUTOSAR standard. And acquiring target dictionary entries of Gaspedal, Mastercylind, DrvSBR and PassSBR which are data items included in the to-be-processed data dictionary Deal _1 based on the identification DOC _ ModelINOUT of the to-be-processed data dictionary Deal _ 1.

In some embodiments of the present application, the identifier based on the to-be-processed data dictionary is implemented by an AUTOSAR standard template in Matlab software, and the target dictionary entry included in the to-be-processed data dictionary is obtained.

Fig. 2 is a schematic flowchart of a method for processing a data dictionary to obtain a target dictionary entry according to an embodiment of the present application. As shown in fig. 2, obtaining the target dictionary entry included in the to-be-processed data dictionary based on the identifier of the to-be-processed data dictionary may be implemented by the following steps:

step S201, responding to the dictionary link instruction, searching a data dictionary library based on the identifier of the data dictionary to be processed in the dictionary link instruction, and acquiring the data dictionary to be processed.

In the embodiment of the application, a database dictionary may be provided. After constructing the to-be-processed data dictionary Deal _1, the user stores the to-be-processed data dictionary Deal _1 into the data dictionary library. In order to obtain a data dictionary corresponding to the to-be-processed data dictionary Deal _1 and conforming to the AUTOSAR standard, a user inputs an identifier DOC _ ModelINOUT of the to-be-processed data dictionary Deal _1 and then triggers a dictionary linkage instruction Command1 through a click operation.

After the dictionary link instruction Command1 is received, searching the data dictionary base based on the identification DOC _ ModelINOUT in the dictionary link instruction Command1, finding the data dictionary identified as DOC _ ModelINOUT, reading information and storing the information into a cache, and thus obtaining the to-be-processed data dictionary Deal _ 1.

In step S202, in response to the dictionary entry setting instruction, dictionary entry configuration information of the to-be-processed data dictionary is acquired from the dictionary entry setting instruction.

Illustratively, the user may trigger the dictionary entry setting Command2 by a click operation after inputting the data items Gaspedal, Mastercylind, drvbsbr, PassSBR of the target dictionary entry.

The dictionary entry configuration information includes, but is not limited to, some or all of the following items: the method comprises the steps of input interface identification, dictionary entry reading sequence of each input interface, and data items of dictionary entries needing to be read by each input interface.

Upon receiving the dictionary entry setting instruction Command2, dictionary entry configuration information Instr2 of the to-be-processed data dictionary Deal _1 is acquired from the dictionary entry setting instruction Command 2. For example, the dictionary entry configuration information Instr2 may be a target dictionary entry indicating "sequentially reading data items Gaspedal, Mastercylind, drvbsbr, and PassSBR, respectively, through the input interface inport 1".

Step S203, according to the acquired dictionary entry configuration information, reading target dictionary entries included in the data dictionary to be processed through the input interface.

In some embodiments of the present application, the input interface is an input port (in port) module in Matlab software. It will be appreciated that the input interface may also be a self-developed designed information reading module. The specific form of the input interface is not limited in this application.

Illustratively, according to the information "the data items sequentially read as target dictionary entries of Gaspedal, Mastercylind, drvbsbr and PassSBR through the input interface inport 1" included in the acquired dictionary entry configuration information Instr2, the data items read as target dictionary entries of Gaspedal, Mastercylind, drvbrb and PassSBR through the input interface inport1 included in the to-be-processed data dictionary Deal _1 are target dictionary entries of Gaspedal, Mastercylind, drvbsbr and PassSBR, respectively.

And S102, packaging the target dictionary entries based on the DDS specification, generating a message structure body corresponding to the target dictionary entries, and storing the message structure body in a preset target communication carrier.

The target communication carrier is used for assisting data transmission of the message structure; the message structure body includes data structure information of the target dictionary entry.

In an embodiment of the present application, the target communication bearer is a virtual bus.

The virtual bus refers to a bus in which a plurality of signals are combined into one bus and then the bus as a whole is accessed, or a specific signal is selected from the bus. In this embodiment, the target communication carrier is a virtual bus, and the preset virtual bus is used to assist data transmission to the message structure.

In specific implementation, after the target dictionary entries are packaged based on the DDS specification to generate a message structure corresponding to the target dictionary entries, the generated message structure is stored in a preset virtual bus according to the DDS specification. When a user inputs a format conversion instruction, the data structure information in the message structure body can be acquired from the virtual bus in response to the received format conversion instruction, so that the data transmission of the message structure body is assisted through the virtual bus.

Illustratively, based on the DDS specification, the data structure information is read from the target dictionary entries of the data items Gaspedal, Mastercylind, drvbsbr, and PassSBR, and encapsulated in the message of the DDS specification, so as to obtain message structure bodies Info _1, Info _2, Info _3, and Info _4 corresponding to the target dictionary entries of the data items Gaspedal, Mastercylind, drvbrb, and PassSBR, respectively, and store the message structure bodies Info _1, Info _2, Info _3, and Info _4 in the preset target communication carrier DOM _ 1. The message structure bodies Info _1, Info _2, Info _3 and Info _4 respectively comprise data structure information of target dictionary entries of which the data items are Gaspedal, Mastercylind, DrvSBR and PassSBR, wherein each message structure body comprises the data structure information of one target dictionary entry.

In some embodiments of the present application, a target dictionary entry is encapsulated based on a DDS specification, and a message structure corresponding to the target dictionary entry is generated, specifically, the method includes: and based on the DDS specification, packaging the target dictionary entries read through the input interface through a message packaging interface corresponding to the input interface to generate a message structure body corresponding to the target dictionary entries read through the input interface.

In specific implementation, the input interface and the message encapsulation interface can be preset to correspond to each other. The target dictionary entry can be read and packaged through an input interface and a message packaging interface corresponding to the input interface; the target dictionary entry may also be read and packaged through a plurality of input interfaces and a plurality of message packaging interfaces respectively corresponding to the input interfaces one to one.

In some embodiments of the present application, the message encapsulation interface is an AUTOSAR event message module in Matlab software.

The following description is made of reading and packaging of a target dictionary entry through one input interface and one message packaging interface corresponding to the one input interface.

Illustratively, assume that the input interface import 1 is set in advance to correspond to the message encapsulation interface event 1. After the input interface inport1 reads the target dictionary entries, the read target dictionary entries are sent to the corresponding message encapsulation interface event 1. Based on the DDS specification, target dictionary entries of Gaspedal, Mastercylind, DrvSBR and PassSBR data items are sequentially read by a message encapsulation interface event1, and are respectively encapsulated in the DDS specification message to obtain message structure bodies Info _1, Info _2, Info _3 and Info _4 corresponding to the target dictionary entries of Gaspedal, Mastercylind, DrvSBR and PassSBR data items.

The manner of reading and packaging the target dictionary entry is performed through the plurality of input interfaces and the plurality of message packaging interfaces respectively corresponding to the input interfaces one to one, which is similar to the aforementioned process.

Based on the DSS specification, when placing a message structure onto a virtual bus, it is usually necessary to provide a corresponding reading module for reading the message structure from the virtual bus. In some embodiments of the present application, a reading module is not provided, and at this time, in order to perform program compilation normally, a mode of connecting a virtual bus to a terminal (Terminator) module in Matlab software is adopted, so as to prevent a compilation error.

Step S103, responding to the received format conversion instruction, acquiring data structure information in the message structure body from the target communication carrier, and performing code conversion on the acquired data structure information to obtain a target data dictionary which accords with AUTOSAR standard.

In specific implementation, the obtained data structure information is subjected to code conversion to obtain a target data dictionary meeting the AUTOSAR standard, specifically, the obtained data structure information is subjected to code conversion to generate an ARXML file corresponding to the data structure information, and the target data dictionary meeting the AUTOSAR standard is obtained.

Illustratively, in response to a received format conversion instruction input by a user, data structure information in the message structures Info _1, Info _2, Info _3 and Info _4 is acquired from the destination communication carrier DOM _1, and the acquired data structure information is transcoded to generate an ARXML file corresponding to the data structure information in the message structures Info _1, Info _2, Info _3 and Info _4, so as to obtain a destination data dictionary Deal _1_ data type, where the destination data dictionary Deal _1_ data type conforms to the AUTOSAR standard.

In some embodiments of the present application, the data structure information in the message structure is obtained from the target communication bearer through an AUTOSAR standard template in Matlab software, and the obtained data structure information is transcoded to obtain a target data dictionary meeting the AUTOSAR standard.

The data dictionary processing method provided by the embodiment of the application includes the steps of firstly obtaining target dictionary entries included by a to-be-processed data dictionary based on identifiers of the to-be-processed data dictionary which does not conform to the AUTOSAR standard, then packaging the target dictionary entries based on DDS (direct digital synthesis) standards, generating message structure bodies corresponding to the target dictionary entries, and storing the message structure bodies into a preset target communication carrier, wherein the message structure bodies include data structure information of the target dictionary entries, responding to a received format conversion instruction, obtaining data structure information in the message structure bodies from the target communication carrier, and performing code conversion on the obtained data structure information to obtain the target data dictionary which conforms to the TOSAR standard. According to the method, the data dictionary which meets the AUTOSAR standard is generated only through the data dictionary which does not meet the AUTOSAR standard, and an automatic driving model and an algorithm dependency library do not need to be loaded, so that the data dictionary which meets the AUTOSAR standard can be generated more conveniently, the time consumption for generating the data dictionary which meets the AUTOSAR standard is saved, and the generation efficiency of the data dictionary which meets the AUTOSAR standard is improved.

Although the embodiments of the present application provide the operational steps of the methods as shown in the above embodiments or figures, more or less operational steps may be included in the above methods based on conventional or non-inventive efforts. In steps where no necessary causal relationship exists logically, the order of execution of the steps is not limited to that provided by the embodiments of the present application. The above methods may be performed in the order of the embodiments or in parallel in the method shown in the drawings when the method is executed in an actual process or apparatus.

In some embodiments of the present application, the method further comprises the step of generating topic identification information. The theme identification information is used for associating the generated message structure body with the theme identification information after the message structure body is generated, and then storing the message structure body into a preset target communication carrier, so that the theme identification information associated with the message structure body in the target communication carrier is determined after the format conversion instruction is received. Before transcoding is carried out on the message structure, compliance judgment of DDS specification is carried out on the basis of the theme identification information, so that the generated target data dictionary can be ensured to meet the AUTOSAR standard, and the generation efficiency of the data dictionary of the AUTOSAR standard is further improved.

Fig. 3 is a schematic flow chart of another data dictionary processing method according to an embodiment of the present application. As shown in fig. 3, the following steps may be included:

step S301, based on the identifier of the data dictionary to be processed, obtaining the target dictionary entry included in the data dictionary to be processed.

The data dictionary to be processed does not accord with AUTOSAR standard;

in step S302, topic identification information corresponding to the target dictionary entry is generated.

In the embodiment of the application, the topic identification information corresponding to the target dictionary entry is generated, and the specific implementation process may be as follows: taking fields extracted from part or all of the target dictionary entries as basic field information; and combining the basic field information with preset additional field information to obtain the subject identification information corresponding to the target dictionary entry.

In specific implementation, the basic field information is combined with the preset additional field information, including but not limited to the following ways: and the preset additional field information is used as a suffix of the basic field information, and the preset additional field information is used as a prefix of the basic field information.

Extracting fields from some or all of the target dictionary entries, including but not limited to: extracting a data item of a first target dictionary entry, extracting a data item of a last target dictionary entry, and extracting the initial of the data item of each target dictionary entry.

Exemplarily, it is assumed that additional field information "_ TOPIC" is preset. The to-be-processed data dictionary Deal _1 comprises 4 target dictionary entries, and the data items of the 4 target dictionary entries are Gaspedal, Mastercylind, DrvSBR and PassSBR respectively. The initial letter of each data item extracted from the target dictionary entry is used as basic field information, for example, the extracted field may be "GMDP"; the basic field information "GMDP" is combined with the preset additional field information "_ TOPIC" by using the preset additional field information as a suffix of the basic field information, to obtain the subject identification information "GMDP _ TOPIC" corresponding to the target dictionary entry.

Step S303, packaging the target dictionary entries based on the DDS specification, and generating a message structure body corresponding to the target dictionary entries.

Wherein the message structure includes data structure information of the target dictionary entry.

And step S304, associating the generated message structure body with the subject identification information.

Illustratively, the message structures Info _1, Info _2, Info _3, Info _4 are associated with the TOPIC identification information "GMDP _ TOPIC", respectively.

Step S305, storing the message structure into a preset target communication carrier.

Wherein the target communication carrier is used for assisting data transmission of the message structure body.

Step S306, after receiving the format conversion instruction, determining that the message structure body in the target communication carrier has the associated theme identification information.

Illustratively, after a format conversion instruction is received, it is first determined that the message structures Info _1, Info _2, Info _3, and Info _4 in the target communication carrier have associated topic identification information. If the message structure bodies Info _1, Info _2, Info _3 and Info _4 in the target communication carrier are determined not to have the associated theme identification information, the transmission of the message structure bodies in the target communication carrier is judged not to conform to the DDS protocol, and in order to ensure that the generated target data dictionaries all conform to the AUTOSAR standard, a user is prompted that the DDS specification is not in compliance and the subsequent steps are stopped.

Specifically, the user is prompted that the DDS specification is not compliant, and a method of triggering an alarm bell, jumping out of prompt information, or the like may be adopted.
