Detailed Implementation

[0019] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of the present invention, including various details to aid understanding. These details should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0020] It should be noted that, unless otherwise specified, the embodiments of the present invention and the technical features thereof can be combined with each other.

[0021] Furthermore, the terms "first," "second," and "third," etc., included in the terminology of this invention are used to distinguish similar objects and are not necessarily used to describe a specific number or order. It should be understood that such terms can be used interchangeably where appropriate; this is merely a distinguishing method used in the embodiments of this invention when describing objects with the same attributes.

[0022] Furthermore, the vehicles involved in the embodiments of the present invention may be internal combustion engine vehicles that use an engine as a power source, hybrid vehicles that use an engine and an electric motor as power sources, electric vehicles that use an electric motor as a power source, etc.

[0023] Figure 1 This is a schematic diagram illustrating the main steps of a computer terminal in a database development scenario based on service communication, according to some embodiments of the present invention. Figure 1 As shown, this service communication-based database development method mainly includes the following steps: Step S101: In response to the creation event of the vehicle database, obtain the preset template and output it.

[0024] In this embodiment, the computer terminal of the present invention can automatically trigger the creation event of the vehicle database, or it can receive the vehicle database creation request sent by the vehicle controller and thus trigger the creation event of the vehicle database. Here, the present invention does not limit the triggering of the creation event.

[0025] Furthermore, in the embodiments, the templates preset by the present invention can be various types of files, such as EXCEL files, FIDL files, etc. The templates can be output for users to fill in service information.

[0026] In a further embodiment of the present invention, the template for step S101 may have options for selecting the operating system type and the version of the service communication protocol for vehicle networking / Ethernet (SOME / IP). In addition, the service information described in the embodiments of the present invention may include at least operating system information and vehicle networking / Ethernet protocol version information.

[0027] Step S102: Receive the returned data for the template, extract the service information from the returned data, generate database source code based on the service information, and save it.

[0028] In some embodiments, the present invention generates database source code based on user-selected or input operating system information, vehicle networking / Ethernet protocol version information, and other relevant service information, and saves it locally. Here, the database source code refers to the program source code of the database system.

[0029] In a further embodiment of the present invention, step S102 can check the acquired service information, and if errors are found, output relevant error messages. The specific implementation process includes: after extracting the service information from the returned data, it includes: calling a preset auditing model to verify the service information; then, in response to the successful verification of the service information, generating database source code based on the service information; or in response to the failed verification of the service information, locating the failed service information, generating and outputting a prompt message. The auditing model can be, but is not limited to, a trained convolutional neural network, recurrent neural network model, or long short-term memory network model, etc. For example: Figure 2 As shown, computer terminal A is configured with a unified template B and outputs it. The received service information is verified and database source code is generated by a tool C (such as DataGrip, DBeaver, etc.). Finally, the database source code is stored and integrated locally on D.

[0030] Step S103: Send the database source code to the vehicle controller that has the same service information.

[0031] In this embodiment, step S103 can send the generated database source code to the vehicle controller that triggered the creation event. Alternatively, the generated database source code can be sent to a vehicle controller with the same service information. It can be seen that as long as the database source code corresponding to the service information is generated, even if the vehicle controller does not send a creation request, the corresponding database source code can be obtained from the computer terminal. As long as the service information used to generate the database source code is consistent, the time and cost of database development are greatly reduced.

[0032] In a further embodiment of the present invention, the present invention can not only simulate and perform performance analysis on the service-based communication database of the vehicle controller, but also simulate and perform performance analysis on service-based communication databases of different operating systems using a computer terminal. For example, when the service-based communication database of the vehicle controller is not fully integrated or the connection fails, simulation can be performed using a computer terminal. The specific implementation process includes: responding to a communication request with the vehicle database, locating the corresponding database source code according to the communication request, and integrating the corresponding database locally using the database source code (e.g., ...). Figure 2 As shown, the database source code is stored in local D of computer terminal A. After local integration, the corresponding database is obtained. Then, a preset simulation program is called (example: such as...). Figure 2As shown, computer terminal A is configured with a simulation program F to perform communication with the database. Therefore, this invention enables computer terminals to perform simulation operations based on service communication databases for different operating systems, and ensures that simulation operations can still be performed even in the event of an malfunction in the vehicle controller, thus ensuring the consistency and effectiveness of the simulation operations. The simulation program is a program that uses computer technology to simulate and reproduce the behavior of the actual system.

[0033] In a further embodiment of the present invention, after performing communication with the database, the present invention can analyze the performance of service-based communication messages, including frame drop rate, latency, jitter, throughput, etc. The specific implementation process includes: acquiring communication messages with the database, and processing the communication messages using a preset performance analysis program (e.g., ...). Figure 2 As shown, computer terminal A is equipped with a performance analysis program (E) to obtain performance analysis data. The performance analysis program refers to a program that evaluates the operating efficiency of a computer program or system by monitoring indicators such as processor utilization, network services, and storage I / O.

[0034] The database development method based on service communication provided in the embodiments of the present invention, such as Figure 3 The diagram illustrates the main steps of a computer terminal in a database development scenario based on service communication, as provided in the second embodiment of the present invention. The embodiments of the present invention include the following steps: Step S301: In response to the creation event of the vehicle database, obtain the preset template and output it.

[0035] Step S302: Receive the returned data for the template and extract the service information from the returned data.

[0036] Step S303: Invoke the preset audit model to verify the service information.

[0037] Step S304: In response to the successful verification of the service information, generate and save the database source code based on the service information.

[0038] Step S305: Send the database source code to the vehicle controller that has the same service information.

[0039] As can be seen, this invention not only enables the unified development of service communication-based databases for different operating systems, but also verifies service information, ensuring the validity of the database source code.

[0040] like Figure 4 The diagram illustrates the main steps of a computer terminal in a database development scenario based on service communication, as provided in the third embodiment of the present invention. The embodiments of the present invention include the following steps: Step S401: In response to the creation event of the vehicle database, obtain the preset template and output it.

[0041] Step S402: Receive the returned data for the template and extract the service information from the returned data.

[0042] Step S403: Invoke the preset audit model to verify the service information.

[0044] Step S405: Receive the modified service information; in response to the successful verification of the modified service information, generate and save the database source code based on the modified service information.

[0045] Step S406: Send the database source code to the vehicle controller that has the same service information.

[0046] As can be seen, this invention can not only develop a unified database based on service communication for different operating systems, but also verify service information and modify service information that fails verification, thus ensuring the generation of database source code.

[0047] like Figure 5 The diagram illustrates the main steps of a computer terminal in a database development scenario based on service communication, as provided in the fourth embodiment of the present invention. The embodiments of the present invention include the following steps: Step S501: In response to the creation event of the vehicle database, obtain the preset template and output it.

[0048] Step S502: Receive the returned data for the template and extract the service information from the returned data.

[0049] Step S503: Generate and save the database source code based on the service information.

[0050] Step S504: Send the database source code to the vehicle controller that has the same service information.

[0051] Step S505: In response to a communication request with the vehicle database, locate the corresponding database source code according to the communication request, and integrate the corresponding database locally using the database source code.

[0052] Step S506: Invoke the preset simulation program to perform communication with the database.

[0053] As can be seen, this invention can not only develop a unified database based on service communication for different operating systems, but also realize communication simulation between different operating systems.

[0054] like Figure 6 The diagram illustrates the main steps of a computer terminal in a database development scenario based on service communication, as provided in the fifth embodiment of the present invention. The embodiments of the present invention include the following steps: Step S601: In response to the creation event of the vehicle database, obtain the preset template and output it.

[0055] Step S602: Receive the returned data for the template and extract the service information from the returned data.

[0056] Step S603: Generate and save the database source code based on the service information.

[0057] Step S604: Send the database source code to the vehicle controller that has the same service information.

[0058] Step S605: In response to a communication request with the vehicle database, locate the corresponding database source code according to the communication request, and integrate the corresponding database locally using the database source code.

[0059] Step S606: Invoke the preset simulation program to perform communication with the database.

[0060] Step S607: Obtain the communication messages with the database, process the communication messages using a preset performance analysis program, and obtain performance analysis data.

[0061] As can be seen, this invention not only enables the unified development of service communication-based databases for different operating systems, but also enables the use of unified tools for service simulation and performance analysis.

[0062] like Figure 7 The diagram illustrates the main steps of an in-vehicle controller in a database development scenario based on service communication, as provided in some embodiments of the present invention. These embodiments include the following steps: Step S701: Receive the database source code sent by the computer terminal, obtain the operating system type in the database source code, and obtain the vehicle operating system type.

[0063] In an embodiment, such as Figure 8As shown, the vehicle controller G can receive database source code sent by a computer terminal via an Ethernet protocol stack K or a vehicle networking protocol stack J, and obtain the operating system type and the operating system type of the vehicle controller from the database source code. Ethernet is a computer local area network (LAN) technology, the vehicle-mounted devices in the connected vehicle communicate via wireless communication technology, and the protocol stack is a specific software implementation of a computer network protocol suite.

[0064] Step S702: In response to the fact that the operating system type is consistent with the vehicle operating system type, construct the corresponding vehicle database based on the database source code.

[0065] In this embodiment, if the operating system type in the database source code matches the operating system type of the vehicle controller, a corresponding vehicle database I can be constructed based on the database source code. Figure 8 (As shown). Of course, if the operating system type in the database source code is inconsistent with the operating system type of the vehicle controller, a database source code mismatch message can be generated and returned to the computer terminal.

[0066] In a further embodiment of the present invention, step S702 can receive a communication request with the vehicle database, establish a communication connection, thereby obtaining communication messages with the vehicle database, calling the performance stub code integrated in the vehicle operating system to process the communication messages and obtain performance analysis data. For example: Figure 8 As shown, performance analysis of communication messages is performed through performance stub code in the application program H within the vehicle controller G. The performance stub code is a code instrument used for performance analysis.

[0067] In a further embodiment of the present invention, if the vehicle controller G of the present invention fails to establish a communication connection, it can forward the communication request to the computer terminal, thereby enabling the computer terminal to perform simulation and performance analysis.

[0068] like Figure 9 The diagram illustrates the main steps of an in-vehicle controller in a database development scenario based on service communication, as provided in the second embodiment of the present invention. The embodiments of the present invention include the following steps: Step S901: Receive the database source code sent by the computer terminal.

[0069] Step S902: Obtain the operating system type from the database source code, and obtain the vehicle operating system type.

[0070] Step S903: In response to the inconsistency between the operating system type and the vehicle operating system type.

[0071] Step S904: Generate a message indicating a database source code mismatch and return it to the computer terminal.

[0072] As can be seen, this invention can not only develop databases based on service communication for different operating systems in a unified manner, but also generate prompts for database source code mismatch, thus ensuring the validity of the database source code.

[0073] like Figure 10 The diagram illustrates the main steps of an in-vehicle controller in a database development scenario based on service communication, as provided in the third embodiment of the present invention. The embodiments of the present invention include the following steps: Step S1001: Receive the database source code sent by the computer terminal.

[0074] Step S1002: Construct the corresponding vehicle database based on the aforementioned database source code.

[0075] Step S1003: Receive a communication request to the vehicle database and establish a communication connection.

[0076] Step S1004: Obtain the communication message with the vehicle database.

[0077] Step S1005: Call the performance stub code integrated in the vehicle operating system to process the communication message and obtain performance analysis data.

[0078] As can be seen, this invention can not only develop databases based on service communication for different operating systems in a unified manner, but also perform performance analysis on databases based on service communication.

[0079] like Figure 11 The diagram illustrates the main steps of an in-vehicle controller in a database development scenario based on service communication, as provided in the fourth embodiment of the present invention. The embodiments of the present invention include the following steps: Step S1101: Receive the database source code sent by the computer terminal.

[0080] Step S1102: Construct the corresponding vehicle database based on the aforementioned database source code.

[0081] Step S1103: Receive a communication request with the vehicle database.

[0082] Step S1104: In response to the failure of the communication connection, forward the communication request to the computer terminal.

[0083] As can be seen, this invention can not only develop databases based on service communication for different operating systems, but also perform service simulation and performance analysis in the event of communication connection failure.

[0084] like Figure 12 This diagram illustrates a service communication-based database development system according to an embodiment of the present invention. The system includes an in-vehicle controller G with different operating systems, such as Classic AUTOSAR operating system M, Adaptive AUTOSAR operating system N, Android operating system P, QNX operating system Q, and Linux operating system R. Each operating system includes an Ethernet protocol stack K, a vehicle networking protocol stack J, a service communication-based database I, and an application program H. The in-vehicle controller G can interact with a computer terminal A via an Ethernet switch L. The computer terminal A is configured with a unified template B and outputs it. A tool C is used to verify the received service information and generate database source code. Finally, the database source code is stored and integrated locally on the computer terminal D. Simultaneously, the computer terminal A is configured with a simulation program F and a performance analysis program E for simulation operations and performance analysis.

[0085] The above steps are provided only to help understand the method, structure, and core ideas of this invention. Those skilled in the art can make various improvements and modifications to this invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims.

[0086] Figure 13 This is a schematic diagram of the main computer terminal unit of a database development apparatus based on service communication according to an embodiment of the present invention. Figure 13 As shown, an embodiment of the present invention provides a database development device 1300 based on service communication, comprising: an acquisition unit 1301, a generation unit 1302, and a sending unit 1303. The acquisition unit 1301 is configured to acquire and output a preset template in response to a vehicle database creation event. The generation unit 1302 is configured to receive return data for the template, extract service information from the return data, generate database source code based on the service information, and save it.

Figure 14 As shown, an embodiment of the present invention provides a database development device 1400 based on service communication, comprising: an acquisition unit 1401 and a processing unit 1402, wherein the acquisition unit 1401 is configured to receive database source code sent by a computer terminal, acquire the operating system type in the database source code, and acquire the vehicle operating system type; the processing unit 1402 is configured to, in response to the operating system type being consistent with the vehicle operating system type, construct a corresponding vehicle database based on the database source code.

[0092] In this embodiment of the invention, the processing unit 1402 is further configured to receive a communication request with the vehicle database and establish a communication connection; obtain a communication message with the vehicle database; call the performance stub code integrated in the vehicle operating system; process the communication message; and obtain performance analysis data.

[0093] In this embodiment of the invention, the processing unit 1402 is further configured to forward the communication request to the computer terminal in response to the failure of the communication connection.

[0094] like Figure 15 As shown, an embodiment of the present invention provides a vehicle 1500, which may include the service-based communication database development device 1400 for vehicles provided in the above embodiments.

[0095] Figure 16 An exemplary vehicle system architecture 1600 is shown, to which the service communication-based database development method or service communication-based database development apparatus of the present invention can be applied.

[0096] like Figure 16As shown, the vehicle system architecture 1600 may include various systems, such as an intelligent driving system 1601, a powertrain system 1602, a sensor system 1603, a control system 1604, one or more peripheral devices 1605, a power supply 1606, a computer system 1607, and a user interface 1608. Optionally, the vehicle system architecture 1600 may include more or fewer systems, and each system may include multiple components. Furthermore, each system and component of the vehicle system architecture 1600 may be interconnected via wired or wireless means.

[0097] The vehicle system architecture 1600 includes an intelligent driving system 1601, which can be in a fully or partially automated driving mode. For example, the intelligent driving system 1601 can automatically control the vehicle's movement without human interaction; the intelligent driving system 1601 can also control the vehicle's automated driving while in automated driving mode, and can also adjust its automated driving behavior through human interaction. Specifically, the intelligent driving system 1601 can also receive database source code sent by a computer terminal, obtain the operating system type in the database source code, and obtain the vehicle operating system type; in response to the operating system type matching the vehicle operating system type, it constructs a corresponding vehicle database based on the database source code.

[0098] The powertrain 1602 may include components that provide power to the vehicle. For example, the powertrain 1602 may include an engine, an energy source, a transmission, wheels, tires, etc. The engine may be an internal combustion engine, an electric motor, an air-compressed engine, or other combinations of engines, such as a hybrid engine consisting of a gasoline engine and an electric motor, or a hybrid engine consisting of an internal combustion engine and an air-compressed engine. The engine converts the energy source into mechanical energy to supply the transmission. Examples of energy sources may include gasoline, diesel, other petroleum-based fuels, propane, other compressed gas-based fuels, ethanol, solar panels, batteries, and other electrical sources. The energy source may also provide energy to other systems in the vehicle. Furthermore, the transmission may include a gearbox, a differential, a drive shaft, and a clutch, etc.

[0099] Sensor system 1603 may include sensors for sensing the vehicle's surrounding environment. Examples include a positioning system (which may be a Global Positioning System (GPS), BeiDou Navigation Satellite System, or other positioning systems), radar, a laser rangefinder, an inertial measurement unit (IMU), and a camera. The positioning system can be used to determine the vehicle's geographical location. The IMU is used to sense changes in the vehicle's position and orientation based on inertial acceleration. In one embodiment, the IMU may be a combination of an accelerometer and a gyroscope. Radar can use radio signals to sense objects in the vehicle's surrounding environment. In some embodiments, in addition to sensing objects, radar can also be used to sense the speed and / or direction of travel of objects.

[0100] To monitor environmental information and objects located in front of, behind, or to the sides of the vehicle, radar, cameras, and other devices can be configured at appropriate locations on the exterior of the vehicle. For example, to acquire an image of the front of the vehicle, a camera can be configured inside the vehicle and close to the windshield. Alternatively, the camera can be configured around the front bumper or radiator grille. Similarly, to acquire an image of the rear of the vehicle, a camera can be configured inside the vehicle and close to the rear window. Alternatively, the camera can be configured around the rear bumper, trunk, or tailgate. To acquire images of the sides of the vehicle, a camera can be configured inside the vehicle and close to at least one of the side windows. Alternatively, the camera can be configured around the side mirrors, fenders, or doors.

[0101] Laser rangefinders use lasers to sense objects in the environment in which a vehicle is located.

[0102] A camera can be used to capture multiple images of the vehicle's surroundings. The camera can be a still camera or a video camera.

[0103] The control system 1604 may include software systems for implementing autonomous driving, such as a route planning system, an obstacle avoidance system, and a vision system for image analysis. The control system 1604 may also include hardware systems such as an accelerator and steering wheel system. Furthermore, the control system 1604 may add or replace components other than those shown and described. Alternatively, some of the components shown above may be reduced.

[0104] The control system 1604 interacts with external sensors, other autonomous driving devices, other computer systems, or users via peripheral devices 1605. Peripheral devices 1605 may include wireless communication systems, on-board computers, microphones, and / or speakers.

[0105] In some embodiments, peripheral device 1605 provides a means for user interaction with the control system 1604 via a user interface. For example, an onboard computer may provide information to a user of the vehicle. The user interface may also operate the onboard computer to receive user input. The onboard computer may be operated via a touchscreen. In other cases, peripheral device may provide a means for communicating with other devices located within the vehicle. For example, a microphone may receive audio (e.g., voice commands or other audio input) from a user of the control system 1604. Similarly, a speaker may output audio to a user of the control system 1604.

[0106] Wireless communication systems can communicate wirelessly with one or more devices, either directly or via a communication network.

The communication section 1709 performs communication processing via a network such as the Internet. A drive 1710 is also connected to I / O interface 1705 as needed. Removable media 1711, such as disks, optical disks, magneto-optical disks, semiconductor memories, etc., are installed on drive 1710 as needed so that computer programs read from them can be installed into storage section 1708 as needed.

[0115] In particular, according to the embodiments disclosed in this invention, the processes described above with reference to the flowcharts can be implemented as computer software programs. For example, embodiments of this invention include a computer program product comprising a computer program carried on a computer-readable medium, the computer program containing program code for performing the methods shown in the flowcharts.

When the computer program is executed by central processing unit (CPU) 1701, it performs the functions defined in the system of this invention.

[0116] It should be noted that the computer-readable medium shown in this invention can be a computer-readable signal medium or a computer-readable storage medium, or any combination thereof. A computer-readable storage medium can be, for example,—but not limited to—an electrical, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device, or any combination thereof. More specific examples of a computer-readable storage medium may include, but are not limited to: an electrical connection having one or more wires, a portable computer disk, a hard disk, random access memory (RAM), read-only memory (ROM), erasable programmable read-only memory (EPROM or flash memory), optical fiber, portable compact disk read-only memory (CD-ROM), optical storage device, magnetic storage device, or any suitable combination thereof. In this invention, a computer-readable storage medium can be any tangible medium containing or storing a program that can be used by or in conjunction with an instruction execution system, apparatus, or device. In this invention, a readable signal medium can include a data signal propagated in baseband or as part of a carrier wave, carrying computer-readable program code. Such propagated data signals can take various forms, including but not limited to electromagnetic signals, optical signals, or any suitable combination thereof. Computer-readable signal media can also be any computer-readable medium other than computer-readable storage media, which can send, propagate, or transmit a program for use by or in connection with an instruction execution system, apparatus, or device.

[0117] The flowcharts and block diagrams in the accompanying drawings illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to various embodiments of the present invention. In this regard, each block in a flowchart or block diagram may represent a module, segment, or portion of code containing one or more executable instructions for implementing a specified logical function. It should also be noted that in some alternative implementations, the functions indicated in the blocks may occur in a different order than those indicated in the drawings. For example, two consecutively indicated blocks may actually be executed substantially in parallel, and they may sometimes be executed in reverse order, depending on the functions involved. It should also be noted that each block in a block diagram or flowchart, and combinations of blocks in a block diagram or flowchart, may be implemented using a dedicated hardware-based system that performs the specified function or operation, or using a combination of dedicated hardware and computer instructions.

[0118] The modules described in the embodiments of the present invention can be implemented in software or hardware. The described modules can also be housed in a processor; for example, a processor can be described as including an acquisition unit and a processing unit. The names of these units do not necessarily limit the module itself; for example, the processing unit can also be described as "a unit for constructing a corresponding vehicle database."

[0119] In another aspect, the present invention also provides a computer-readable medium, which may be included in the device described in the above embodiments; or it may exist independently and not assembled into the device. The computer-readable medium carries one or more programs that, when executed by the device, cause the device to: in response to a creation event of an in-vehicle database, acquire and output a preset template; receive return data for the template, extract service information from the return data, generate and save database source code based on the service information; and send the database source code to an in-vehicle controller having the same service information.

[0120] Alternatively, the aforementioned computer-readable medium may carry one or more programs, which, when executed by a device, cause the device to include: receiving database source code sent by a computer terminal, obtaining the operating system type in the database source code, and obtaining the vehicle operating system type; and, in response to the operating system type being consistent with the vehicle operating system type, constructing a corresponding vehicle database based on the database source code.

[0121] According to the technical solution of the embodiments of the present invention, the present invention can solve the technical problems of high cost, low efficiency, and inability to perform simulation and performance analysis of existing cross-operating system-based service communication databases; thereby realizing the ability to develop service communication-based databases uniformly for different operating systems, significantly reducing development costs and avoiding development risks, while using unified tools for service simulation and performance analysis, eliminating the need to develop and deploy simulation code and performance analysis code separately for different operating systems.
