Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application for protection, but merely represents the selected embodiment of the present application.

[0022] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0023] See also Figure 1 , Figure 1 A flow chart of a data acquisition method proposed according to an embodiment of the present application is shown, which is used for a vehicle, and the method includes:

[0024] S110. In response to a data acquisition request from a data acquisition unit, target service information corresponding to a target service requested by the data acquisition request is acquired from a target service configuration file.

[0025] Among them, the target service configuration file includes the service information of each of the multiple services; the target service configuration file is generated based on the server message sent by the data acquisition protocol stack in the data acquisition unit; the server message is sent to the data acquisition protocol stack by the service unit providing multiple services, and the server message is generated by the service unit providing multiple services according to the service information for the multiple services.

[0026] The service can be a SOA (Service-Oriented Architecture) service in the vehicle. The service can include services in the cabin domain, services in the intelligent driving domain, and services in the entertainment domain. The services in the cabin domain include air conditioning services, lighting services, seat services, etc. in the cabin. The services in the intelligent driving domain include automatic lane change services, automatic steering services, and automatic parking services, etc. The services in the entertainment domain include music services, video services, etc.

[0027] The service information of a service is used to describe the service attributes of the service. For example, the service information of a service may include the service instance, version, life cycle, stage of the service, service availability status and deployment information of the service; wherein, the service instance of a service refers to an instance of the service, that is, a concrete example of the service, the version of the service is the version number of the current service, the life cycle of the service refers to the entire process of creating, starting, running and ending the service, the stage of the service refers to a process in which the service is in the entire life cycle, the service availability status refers to whether the service is available, and the deployment information of the service may include the IP address and port number of the service, etc.

[0028] The unit in the vehicle used to provide the aforementioned services is referred to as a service unit, and the unit in the vehicle used to obtain data for each service is referred to as a data acquisition unit. The data acquisition unit can integrate a data acquisition application to implement the data acquisition method of the present application through the data acquisition application, that is, the data acquisition unit can serve as an execution entity to implement the data acquisition method of the present application.

[0029] In another embodiment, the vehicle can also serve as an execution subject. The vehicle integrates a data acquisition application that implements the data acquisition method of the present application, and interacts with the data acquisition unit through the data acquisition application to implement the data acquisition method of the present application.

[0030] The vehicle may be an electric vehicle or a fuel vehicle, or a sedan, SUV, bus, truck, etc. The data acquisition unit may be a central computing component in the vehicle, which is used to process and make decisions on the data collected by the vehicle.

[0031] In this embodiment, a service unit can provide at least one service, and the multiple services involved can be provided by at least one service unit. The service unit refers to a control unit in the vehicle for providing services; for example, Tbox can be a service unit, and for example, an entertainment center can be used as a service unit, and for example, an autonomous driving module can also be used as a service unit (a sub-module in the autonomous driving module can also be used as a service unit, for example, the automatic lane change sub-module is a service unit).

[0032] In this embodiment, the data acquisition unit and the service unit communicate through the data acquisition protocol stack to realize data interaction between the data acquisition unit and the service unit. The data acquisition protocol stack can be a SOME / IP protocol stack, that is, the data acquisition unit and the service unit communicate through the SOME / IP protocol. In addition, different service units can also communicate through the SOME / IP protocol, that is, different service units all have a SOME / IP protocol stack, and the service units communicate with each other through their respective SOME / IP protocol stacks.

[0033] For each service unit, the service unit can generate an information message (such as a SOMEIP SD Offer message) as a server message based on the service information of the service provided by the service unit; the server message here includes the server messages generated by all service units used to provide the aforementioned multiple services. Among them, all service units used to provide the aforementioned multiple services can periodically send the server messages to the data acquisition protocol stack in the data acquisition unit. For example, every 1 second or every 2 seconds, all service units used to provide the aforementioned multiple services generate a server message based on the service information for multiple services, and send the server message to the data acquisition protocol stack in the data acquisition unit.

[0034] After the data acquisition protocol stack obtains the server message, it can send the server message. At this time, the vehicle (or the data acquisition unit in the vehicle) receives the server message sent by the data acquisition protocol stack; extracts multiple services and their respective service information from the server message; encapsulates the multiple services and their respective service information to obtain the target service configuration file.

[0035] That is to say, the service unit for providing multiple services sends a server message for multiple services (the server message includes the server message generated by each service unit), and extracts the service information corresponding to the service from the server message, one service corresponds to one service information. After extracting each service and the service information corresponding to each service, the multiple services and the service information corresponding to the multiple services can be summarized, and the summarized results can be encapsulated to obtain the target service configuration file.

[0036] In some embodiments, the data acquisition method can be implemented through a data acquisition application, which can be deployed in a vehicle or a data acquisition unit of a vehicle. The data acquisition application can be provided with three modules: a dynamic service discovery module, a service information cache module, and a service information management module, so as to implement the data acquisition method of the present application through three modules.

[0037] Exemplarily, the dynamic service discovery module periodically (e.g., every 1s or every 2s) communicates with the SOME / IP protocol stack in the data acquisition unit (i.e., the aforementioned data acquisition protocol stack) to obtain the server message (the server message includes multiple services and service information of each of the multiple services). The SOME / IP protocol stack in the data acquisition unit can receive the server message sent by the service unit periodically (e.g., every 1s or every 2s) for multiple services, so that the dynamic service discovery module can obtain the server message from the SOME / IP protocol stack.

[0038] Afterwards, the service information caching module summarizes the service information of multiple services and multiple services in the server message into a service information list, and caches it as a service information list. Afterwards, the service information management module obtains the service information from the service information list, and encapsulates the service information obtained from the service information list as an API interface (Application Programming Interface), and obtains a service configuration file in the vsomeip.json format as the target service configuration file. The target service configuration file can provide the service information to other unit applications in the vehicle in the form of SOME / IP service.

[0039] In some embodiments, before receiving the server message sent by the data acquisition protocol stack, the method may include: in response to a target event trigger, sending a service information acquisition request to a service unit providing multiple services through the data acquisition protocol stack, so that the service unit providing multiple services returns the server message based on the service information acquisition request. The target event may include the first startup of the data acquisition application, the power-on of the vehicle, or the power-on of the data acquisition unit.

[0040] That is, when a target event occurs, the vehicle (or the vehicle's data acquisition unit) actively sends a service information acquisition request to the service unit providing multiple services through the data acquisition protocol stack. The service information acquisition request is used to request the service unit providing multiple services to return a server message.

[0041] In this embodiment, the data acquisition request can be generated based on the user's data acquisition operation for the target service, or it can be generated by the vehicle in response to a target event. The target event may refer to an event that requires obtaining data for the target service. For example, if the target service is air conditioning service, the target event may be powering on the vehicle, etc.

[0042] In some implementations, after obtaining the target service configuration file, a query interface corresponding to the target service may be obtained; and target service information corresponding to the target service may be obtained from the target service configuration file through the query interface corresponding to the target service.

[0043] In this embodiment, two types of query interfaces can be set: one SOME / IP R / R method interface for querying service information of a single service (for the sake of ease of description, this interface is referred to as the first query interface here) and one SOME / IP R / R method interface for querying service information of all services (for the sake of ease of description, this interface is referred to as the second query interface here).

[0044] When the target service is one or several services, the first query interface of each target service is called to obtain the target service information of the target service from the target service configuration file; when the target service is all services, the second query interface is called to obtain the service information of all services from the target service configuration file as the target service information.

[0045] S120. Obtain a payload return value corresponding to the target service from the target service unit corresponding to the target service according to the target service information as target data requested by the data acquisition request, and return the target data to the data acquisition unit.

[0046] The service unit providing the target service is used as the target service unit, and the vehicle or the data acquisition unit in the vehicle obtains the payload return value corresponding to the target service from the target service unit corresponding to the target service according to the target service information as the target data. If the execution subject of the data acquisition method of the present application is a vehicle, the vehicle returns the target data to the data acquisition unit. If the execution subject of the data acquisition method of the present application is the data acquisition unit, after the data acquisition unit obtains the payload return value corresponding to the target service, it can directly use the payload return value corresponding to the target service as the target data to be acquired.

[0047] In the present application, after obtaining the target service information of the target service from the target service configuration file, the target service for which SOME / IP data needs to be collected can be determined according to the target service information by calling or subscribing, and then the target service's payload return value (the format of SOME / IP data) is obtained from the target service unit corresponding to the target service as the target data requested by the data acquisition request.

[0048] After obtaining the target data, data management operations can be performed on the target data: splitting, reorganizing, storing or uploading (uploading to the cloud connected to the vehicle communication) and other operations.

[0049] Exemplarily, the data acquisition process is as follows: Figure 2 As shown, the data acquisition unit on the vehicle serves as the execution entity, and the data acquisition unit is also configured with a dynamic service discovery module, a service information storage module, a service information management module and a SOME / IP protocol stack, so as to obtain the target service configuration file through the dynamic service discovery module, the service information storage module and the service information management module, and implement the aforementioned S110-S120 data acquisition process through the generated target service configuration file.

[0050] First, service information sent by service unit 1, service unit 2, ..., service unit n for multiple services is received through the SOME / IP protocol stack; then, the dynamic service discovery module obtains the service information of the multiple services from the SOME / IP protocol stack, and the service information cache module summarizes the service information of the multiple services into a service information list and caches it as a service information list; then, the service information management module obtains the service information from the service information list and encapsulates the service information obtained from the service information list into a target service configuration file.

[0051] Afterwards, the data acquisition unit determines target service information of the target service using the target service configuration file, and then acquires target data according to the target service information.

[0052] In this embodiment, the target service configuration file includes service information of each of the multiple services, and directly responds to the data acquisition request, obtains the target service information corresponding to the target service requested by the data acquisition request from the target service configuration file, and then obtains the payload return value corresponding to the target service according to the target service information, as the target data requested by the data acquisition request. It is not necessary to obtain the target service information of the target service from the provider of the target service after receiving the data acquisition request, which saves the interaction time with the service provider of the target service, improves the efficiency of obtaining the target service information, and further improves the efficiency of obtaining the target data according to the target service information.

[0053] At the same time, the target service configuration file is generated based on the server message sent by the data acquisition protocol stack in the data acquisition unit; the server message is sent to the data acquisition protocol stack by the service unit providing multiple services, and the server message is generated by the service unit providing multiple services according to the service information for multiple services. The whole process does not require user participation, thereby realizing the process of automatic generation of the target service configuration file by the vehicle, and there is no need to manually configure the target service configuration file, which reduces the time consumption of manually configuring the target service configuration file and improves the generation efficiency of the target service configuration file.

[0054] In one embodiment, if Figure 3 As shown, step S110 may include:

[0055] S210: In response to the data acquisition request, determine whether there is target service information corresponding to the target service in an existing service configuration file.

[0056] Among them, the existing service configuration file is generated based on the existing server message sent by the data acquisition protocol stack; the existing server message is generated by a service unit providing multiple existing services and sent to the data acquisition protocol stack, and the existing server message is generated by the service unit providing multiple existing services according to service information for multiple existing services.

[0057] That is to say, before receiving the data acquisition request, there is already a service configuration file, which is used as an existing service configuration file, and a service in the existing service configuration file is used as an existing service. At this time, the existing service configuration file includes multiple existing services and service information corresponding to each of the multiple existing services.

[0058] In this embodiment, the service unit providing the existing service generates an information message as an existing server message based on the service information for the existing service, and then sends the existing service message to the data acquisition protocol stack of the data acquisition unit. Thereafter, the vehicle (or data acquisition unit) can receive the existing server message sent by the data acquisition protocol stack, and encapsulate it into a service configuration file according to the aforementioned process based on the existing server message as the existing service configuration file, and then, when receiving a data acquisition request, determine whether the target service information corresponding to the target service exists in the existing service configuration file.

[0059] S220: If the target service information corresponding to the target service exists in the existing service configuration file, obtain the existing service configuration file as the target service configuration file; and obtain the target service information corresponding to the target service from the target service configuration file.

[0060] If the target service information corresponding to the target service exists in the existing service configuration file, it means that the target service information corresponding to the target service can be obtained from the existing service configuration file. Therefore, the existing service configuration file is directly used as the target service configuration file, and then the target service information corresponding to the target service is obtained from the target service configuration file. At this time, an existing service in the existing service configuration file is a service in the target service configuration file.

[0061] S230. If the target service information corresponding to the target service does not exist in the existing service configuration file, obtain an update service message from the service unit providing the update service through the data acquisition protocol stack; update the existing service configuration file according to the update service and the service information corresponding to the update service in the update service message to obtain the target service configuration file; obtain the target service information corresponding to the target service from the target service configuration file.

[0062] The update service end message is generated by a service unit providing update service according to service information for update service.

[0063] If the target service information corresponding to the target service does not exist in the existing service configuration file, it means that the target service information corresponding to the target service cannot be obtained from the existing service configuration file. At this time, an update service message can be obtained from the service unit used to provide the update service (the update service message is an information message generated by the service unit providing the update service according to the service information for the update service). After obtaining the update service message, the update service and the service information corresponding to the update service can be extracted from the update service message, and then the update service and the service information corresponding to the update service can be added to the existing service configuration file to update the existing service configuration file and obtain the target service configuration file.

[0064] Generally speaking, all services involved in a vehicle are fixed, and the existing services in an existing service configuration file are all or part of all services involved in the vehicle. However, there is no target service information corresponding to the target service in the existing service configuration file, which means that the existing service in the existing service configuration file is only a part of all services involved in the vehicle, and the existing service configuration file at least lacks the service information of the target service. At this time, the target service can be obtained as an update service, or other services among all services involved in the vehicle except the existing services included in the existing service configuration file can be obtained as update services, and then an update service-side message can be obtained from the service unit providing the update service.

[0065] In some embodiments, if the target service information corresponding to the target service does not exist in the existing service configuration file, all services involved in the vehicle can be directly obtained as update services, and an update service message can be obtained from the service unit providing the update service, and then based on the update service message, a service configuration file is generated according to the aforementioned process, and the service configuration file is used as the target service configuration file. At this time, after obtaining the target service configuration file, the existing service configuration file can also be deleted to avoid the storage of redundant and repeated data and free up storage space.

[0066] In this embodiment, if the target service information corresponding to the target service exists in an existing service configuration file, the target service information corresponding to the target service is directly obtained from the existing service configuration file; if the target service information corresponding to the target service does not exist in the existing service configuration file, the existing service configuration file is updated to obtain the target service configuration file, and then the target service information corresponding to the target service is obtained from the target service configuration file, thereby realizing real-time update of the service information of multiple services, so as to accurately and quickly obtain the target service information of the target service.
