The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments.

In the current SOA architecture development, the SOME/IP protocol is mostly tested (such as TC 83.0), and the SOA service carried on the SOME/IP protocol is rarely designed in detail. For the SOME/IP protocol and the reverse test, only the correctness of the SOMEIP protocol can be verified, the functional scenes of the internal logic design and the interface of the SOA service cannot be covered, and the lower-layer logic problem can not be found earlier before the functional point inspection test. Referring to fig. 1 for solving the above problem, an embodiment of the present application provides a flow diagram of a vehicle detection method based on SOA service, which specifically includes:

s110, under the condition that socket connection is established with a core server A of a target vehicle, sending a test request message to the core server A so that a target interface feeds back a test response message;

illustratively, the vehicle testing device may be implemented by a PC upper computer or a dedicated testing tool, and when the vehicle testing device establishes a socket connection with the core a server, the vehicle testing device sends a test request message to the core a server, and calls a target interface corresponding to the request message through a vehicle network system, so that the vehicle ECU or the testing device to be tested generates an instruction based on the request message, and generates a test response message based on the instruction. The sent test request message can simultaneously call a plurality of interfaces so as to simultaneously complete the test work of a plurality of services, and a test scheme with richer internal logic can be set based on different scenes of the vehicle.

It should be noted that, in SOME vehicles, original data is encapsulated by the M core, and the a core performs packet encapsulation and issuance by using its SOME/IP protocol stack, so that the influence of insufficient computation power of the M core can be eliminated, and the advantages of small product of the M core, simplicity and easy operation can be exerted. Meanwhile, the core A has strong calculation power, so that services are added in the subsequent process of the product, the product is not influenced by the calculation resources of the core M, and the iteration and the expansion can be flexibly realized.

S120, receiving the test response message;

illustratively, the test device receives the response message and stores the response message in a memory of the test device, where the test response message includes the target port information and the response data collected by each target port.

And S130, acquiring the detection result of the target vehicle based on the test response message and the test request message.

For example, the obtaining of the detection result may be generating the detection result based on the complete test response message and the complete test request message after the whole test process is finished, or displaying the deviation between the measurement result and the expected result in real time in the detection process, so that the engineer can find the test problem in time.

In summary, the vehicle detection method based on the SOA service provided by the embodiment of the present application establishes a socket connection with the a-core processor through the test device, directly sends a scene-like test request message to the a-core processor, and obtains a detection result of the target vehicle based on the test response message obtained by the target port.

In some examples, the method further comprises:

Illustratively, before a socket connection is opened, two steps of socket and Bind are required to be completed. Socket is to create a new Socket and Bind specifies the IP and port of the Socket (the client will be assigned a port by the system when invoking Connect, so Bind can be omitted). And the server side starts monitoring through Listen and waits for the access of the client side. The client is connected with the server through the Connect, and the server receives the client connection through the Accept. During the connect-accept process, the operating system will perform a three-way handshake. The client and the server send and receive data through write and read, and the operating system completes the steps of confirming, retransmitting and the like of the TCP data. When the test equipment is connected with the vehicle end, information such as configuration information, an IP address, a transmission protocol, a port number and the like of the A-core server needs to be determined so as to ensure correct connection and avoid errors before testing.

In summary, according to the vehicle detection method based on the SOA service provided in the embodiment of the present application, the configuration information, the IP address, the transport protocol, and the port number of the core a server are set correctly in the request connection message, so that the socket connection can be established with the core a server quickly, and the vehicle detection based on the core a server is realized.

In some examples, the method further comprises:

Illustratively, the connection between the PC and the in-vehicle system is realized by connecting the PC and a DUT (Device Under Test) through an ethernet converter, where the DUT, i.e., the Device Under Test, may be an in-vehicle ECU

In some examples, the test request message includes a target interface name, test parameters, and a service ID.

Illustratively, to call a correct interface and ID, a corresponding target interface name and service ID need to be determined for a function implemented by the request message, so as to call the correct target interface and target service, meanwhile, a specific test parameter is set based on a test item, a device under test or an ECU generates a response parameter based on the test parameter, generates a response message, and can determine a state of a corresponding device under test based on the test parameter in the request message and the response parameter in the response message.

In some examples, the method further comprises:

Illustratively, the interface document information is a corresponding relation between a target interface name and a service ID determined in the vehicle development process, and the function can be called smoothly only by the interface name and the service ID with determined accuracy.

In summary, the vehicle detection method based on the SOA service provided by the embodiment of the present application can accurately invoke a target interface and a service based on interface document information, ensure the correctness of invocation, and avoid a test process failure caused by an interface invocation and a service error.

In some examples, the method further comprises:

For example, SOME network layer tests cannot be performed by sending test packets with an a-core processor, for example, a SOME IP/SD message parameter test, a sending mode test, a routing test, and the like, and at this time, the contents of the SOME IP protocol of the network layer need to be directly accessed to complete the network layer tests. SD (Service Discovery) belongs to a very core content in the SOME/IP protocol, and mainly provides functions of detecting and providing available services. The advantages of SD are as follows: when the vehicle is electrified and started, the starting voltage and the starting time of each ECU in the vehicle are different, and the ECU can flexibly declare the available state of the Service through the SD; when the vehicle is deformed (different configurations of the same type of vehicle or vehicle type follow-up), the change of functions/configurations can be flexibly adapted, and the configuration work in the early stage is reduced; and error processing, when the provided Service has a problem, the SD can immediately know the unavailable state of the Service, the receiver can correspondingly process the energy efficiency, and the receiver can provide/subscribe the Service when necessary, so that the capacity consumption is reduced. SD communication mainly involves type 3 messages: a Find Service, an Offer Service and a Subscribe message.

In summary, the vehicle detection method based on the SOA service provided in the embodiment of the present application completes the network layer test by directly accessing the content of the SOME IP protocol in the network layer for the content that cannot be tested by the a-core processor in the network layer, thereby ensuring the comprehensiveness of the vehicle test.

In SOME examples, the SOME IP protocol contents of the direct access network layer include:

Illustratively, a CANoe is a comprehensive software tool that can be used for the development, testing, and analysis of the entire ECU and the entire vehicle network. From vehicle planning to system level testing, assistance is provided for network designers, development engineers, and test engineers of automotive manufacturers and suppliers throughout the development process. The method can be used for automatic testing in the development and testing stages of network layer processing, can simulate and test the ECU diagnostic function in the vehicle, finds and modifies the error state in the early stage of the development process, and can evaluate the result based on graphs/texts. CANoe can analyze the multi-bus communication of the ECU and the entire system in a desktop development environment as in a vehicle. The diagnostic functionality accompanying CANoe supports diagnostic communication analysis based on the KWP2000 and UDS standards. CANoe can be used both as a diagnostic tester and for simulation of ECU diagnostic functions and parameterized using ODX or candelas description files. The simulation of the entire network and the remaining bus simulation are performed using CANoe, which may also be generated manually or automatically from a communications database. Simulating the communication operation of the entire network or individual ECUs as the remaining bus is the basis for the subsequent analysis phase and test phase.

In summary, the vehicle detection method based on the SOA service provided by the embodiment of the present application directly accesses the SOME IP protocol content of the network layer through the CANoe tool, and can implement the network layer test automation visualization operation.

In some examples, as shown in FIG. 2, vehicle testing may be accomplished by:

s210, connecting the PC and the DUT through the Ethernet converter to realize the connection of the PC and the vehicle machine system, wherein the DUT is the tested equipment and can be a vehicle machine ECU;

and S220, establishing socket connection on the PC end upper computer, and connecting the socket connection with the core A server. When the socket connection is established at the PC end, configuration information, an IP address and a transport protocol core port number of the A core server need to be contained, and the successful connection is ensured.

When the connection of the S230, the PC and the A core server socket is normal, the API interfaces of the public SOMEIP server and the client can be called, and the derived interfaces of each service can also be called. When the interface is called for interface test, the interface name and the service ID must strictly correspond to the interface document, and the service ID must strictly correspond to the server ID in the configuration file someip _ config.

Referring to fig. 3, an embodiment of the vehicle detection control apparatus based on the SOA service in the embodiment of the present application may include:

a sending unit 21, configured to send a test request message to an a-core server of a target vehicle to enable a target interface to feed back a test response message when a socket connection is established with the a-core server;

a receiving unit 22, configured to receive the test response message;

and the detection unit 23 is configured to obtain a detection result of the target vehicle based on the test response message and the test request message.

In summary, the vehicle detection method based on the SOA service provided in the embodiment of the present application establishes socket connection with the a-core processor through the test device, directly sends a scenic test request message to the a-core processor, and obtains a detection result of a target vehicle based on a test response message obtained by a target port.
