Description

[0002] Vehicles are increasingly equipped with electronic control units (ECUs), which control the functions of certain vehicle components and monitor and record their operating status. Users can access data from these ECUs to diagnose the vehicle's operating status, identify and correct faults, and ensure safe operation.

[0003] Currently, a diagnostic service is provided in the electronic control unit, which can be used as a server device for vehicle diagnosis.

[0045] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features therein can be combined with each other in the absence of conflict.

[0050] In order to better understand the inventive concept of the embodiments of the present disclosure, the technical solutions of the embodiments of the present disclosure are described below in conjunction with exemplary embodiments.

[0051] Figure 1 This is a flow chart of a vehicle diagnostic method provided by an embodiment of the present disclosure. This method can be executed by a server device set in a vehicle. The device can be understood as any device with processing and computing capabilities. The server device can be any electronic control unit in the vehicle. Figure 1 As shown, the vehicle diagnostic method provided in this embodiment includes the following steps:

[0052] Step 110: In response to receiving at least one diagnostic instruction from the client device, obtain a diagnostic service identifier requested by each diagnostic instruction from the diagnostic instruction.

[0053] In the embodiments of the present disclosure, the client device may be understood as a device for diagnosing a vehicle, such as a vehicle diagnostic instrument.

[0054] In the disclosed embodiments, a client device may establish a communication connection with a server device within a vehicle, for example, via the Diagnostic Over Internet Protocol (DOIP). DOIP is an Ethernet-based onboard diagnostic protocol that is part of the ISO 13400 standard.

[0055] When a user needs to diagnose a vehicle, they can perform a diagnostic operation on the client device, for example, by clicking on at least one target diagnostic service on the client device interface. In response to the user's diagnostic operation, the client device can generate at least one diagnostic instruction, each of which can include the diagnostic service identifier of the requested target diagnostic service, and then send the at least one diagnostic instruction to the server device. A diagnostic service identifier can be understood as information that uniquely identifies a diagnostic service. There is a one-to-one correspondence between a diagnostic service identifier and a diagnostic service.

[0056] The server device may include an edge node (diag-edge) and at least one pre-defined diagnostic service (server). The diagnostic service can be understood as an application based on the standard protocol of Unified Diagnostic Services (UDS) that provides unified diagnostic services and can perform functions such as diagnostic flashing and data injection. The edge node is an application, and each diagnostic service corresponds to a diagnostic business. In other words, one diagnostic service can implement a diagnostic business.

[0057] In response to receiving at least one diagnostic instruction from the client device, the edge node in the server device may obtain the diagnostic service identifier requested by the diagnostic instruction from each diagnostic instruction.

[0058] Step 120: Search for a target diagnostic service corresponding to each diagnostic service identifier from at least one preset diagnostic service. Each diagnostic service corresponds to a diagnostic service, and each diagnostic service processes the corresponding diagnostic service independently.

[0059] In the disclosed embodiment, after obtaining the diagnostic service identifier of at least one diagnostic instruction request, the edge node in the server device can search for the target diagnostic service corresponding to each diagnostic service identifier from at least one preset diagnostic service based on the mapping relationship between the diagnostic service identifier and the diagnostic service. Each diagnostic service corresponds to a diagnostic service, and each diagnostic service independently processes the corresponding diagnostic service. That is, each diagnostic service can process diagnostic services in parallel without affecting each other.

[0060] In some embodiments, searching for a target diagnostic service corresponding to each diagnostic service identifier from at least one preset diagnostic service may include steps 1201-1202:

[0061] Step 1201: Determine a target logical storage address corresponding to the diagnostic service identifier based on a mapping relationship between the diagnostic service identifier and the logical storage address.

[0062] In the embodiment of the present disclosure, after obtaining the diagnostic service identifier requested by the diagnostic instruction, the edge node in the server device can use the mapping relationship between the diagnostic service identifier and the logical storage address to determine the target logical storage address corresponding to the diagnostic service identifier.

[0063] Step 1202: Determine the diagnostic service corresponding to the target logical storage address as the target diagnostic service corresponding to the diagnostic service identifier.

[0064] In the disclosed embodiment, each logical storage address corresponds to a diagnostic service. The logical storage address can be understood as the logical address of the storage space of the server device storing the diagnostic service. The edge node in the server device can determine the diagnostic service corresponding to the target logical storage address as the target diagnostic service corresponding to the diagnostic service identifier.

[0065] Step 130: For each diagnostic instruction, execute the diagnostic instruction based on the target diagnostic service corresponding to the diagnostic service identifier in the diagnostic instruction and generate a diagnostic result.

[0066] In the disclosed embodiments, the edge node in the server device and the diagnostic service can communicate, for example, via the Diagnostic Internet Protocol (DOIP). For each diagnostic instruction, the edge node in the server device can forward the instruction to the corresponding target diagnostic service. The target diagnostic service can then execute the instruction and generate a diagnostic result.

[0067] Step 140: Forward the diagnostic results generated by each target diagnostic service to the client device.

[0068] In the embodiment of the present disclosure, each target diagnostic service in the server device may send the generated diagnostic result to the edge node in the server device, and the edge node may forward the diagnostic result generated by each target diagnostic service to the client device.

[0069] In an embodiment of the present disclosure, a server device in a vehicle responds to receiving at least one diagnostic instruction from a client device, obtains a diagnostic service identifier requested by the diagnostic instruction from each diagnostic instruction; searches for a target diagnostic service corresponding to each diagnostic service identifier from at least one preset diagnostic service, each diagnostic service corresponds to a diagnostic business, and each diagnostic service processes the corresponding diagnostic business independently of each other; for each diagnostic instruction, the diagnostic instruction is executed and a diagnostic result is generated based on the target diagnostic service corresponding to the diagnostic service identifier in the diagnostic instruction; the diagnostic result generated by each target diagnostic service is forwarded to the client device. Multiple independent diagnostic services can be set in the server device, each diagnostic service can run independently, and multiple diagnostic services can execute multiple diagnostic instructions in parallel, thereby improving diagnostic efficiency. In addition, when the diagnostic service needs to be modified or its functions need to be adjusted and added, it is only necessary to modify or adjust it in the corresponding diagnostic service. When the function of the diagnostic service needs to be expanded, it is only necessary to add a diagnostic service with the corresponding function without modifying the existing diagnostic service program, thereby improving the scalability of the diagnostic service and reducing the development difficulty and cost of the diagnostic service.

[0070] In some embodiments of the present disclosure, when searching for the target diagnostic service corresponding to the diagnostic service identifier from at least one preset diagnostic service, if the edge node in the server device does not find the target diagnostic service corresponding to the diagnostic service identifier from at least one preset diagnostic service, it can be determined that the search for the target diagnostic service corresponding to the diagnostic service identifier has failed. In response to the failure to search for the target diagnostic service corresponding to the diagnostic service identifier, the edge node in the server device can send a first alarm message to the client device, and the first alarm message may include the inability to find the target diagnostic service corresponding to the diagnostic service identifier.

[0071] Figure 2 This is a flow chart of a vehicle diagnostic method provided by an embodiment of the present disclosure. The method can be executed by a server device disposed in a vehicle, such as Figure 2 As shown, the vehicle diagnostic method provided in this embodiment includes the following steps:

[0072] Step 210: In response to receiving at least one diagnostic instruction from the client device, obtain a diagnostic service identifier requested by the diagnostic instruction from each diagnostic instruction.

[0073] Step 220: Search for a target diagnostic service corresponding to each diagnostic service identifier from at least one preset diagnostic service. Each diagnostic service corresponds to a diagnostic service, and each diagnostic service processes the corresponding diagnostic service independently.

[0074] Step 230: For each target diagnostic service, construct a session service corresponding to the target diagnostic service.

[0075] In the embodiment of the present disclosure, after finding the target diagnostic service corresponding to each diagnostic service identifier, the edge node in the server device can build a session service corresponding to each target diagnostic service.

[0076] Step 240: Receive at least one diagnostic message corresponding to the diagnostic instruction processed by the target diagnostic service based on the session service.

[0077] In the embodiment of the present disclosure, the edge node in the server device may receive at least one diagnostic message corresponding to the diagnostic instruction processed by the target diagnostic service based on the session service corresponding to the target diagnostic service.

[0078] Step 250: Sort at least one diagnostic message according to the order in which the diagnostic messages are received to obtain a message queue.

[0079] In the embodiment of the present disclosure, the edge node in the server device may sort at least one diagnostic message according to the order in which the diagnostic messages are received to obtain a message queue, which includes at least one diagnostic message.

[0080] Step 260 : Execute the diagnostic messages in the message queue in sequence based on the target diagnostic service according to the message sequence of the message queue to obtain the diagnostic results corresponding to the diagnostic instructions.

[0081] In the embodiment of the present disclosure, the edge node in the server device can execute the diagnostic messages in the message queue in sequence based on the target diagnostic service according to the message order of the message queue, and then obtain the diagnostic result corresponding to the diagnostic instruction.

[0082] Step 270: Forward the diagnostic results generated by each target diagnostic service to the client device.

[0083] For example, Figure 3 FIG. 1 is a schematic diagram of a session manager in an edge node according to an embodiment of the present disclosure. Figure 3 As shown, after receiving the diagnostic instruction 311 sent by the client device and determining the target diagnostic service 331 corresponding to the diagnostic service identifier in the diagnostic instruction 311, the session manager of the edge node in the server device can construct a session service 321 corresponding to the target diagnostic service 331. The session service 321 can receive at least one diagnostic message corresponding to the diagnostic instruction 311, and then sort the at least one diagnostic message according to the order in which the diagnostic messages are received to obtain a message queue 1. Then, according to the message order of the message queue 1, the diagnostic messages in the message queue 1 are executed in sequence based on the target diagnostic service 331 to obtain a diagnostic result corresponding to the diagnostic instruction 311.

[0084] After receiving the diagnostic instruction 312 sent by the client device and determining the target diagnostic service 332 corresponding to the diagnostic service identifier in the diagnostic instruction 312, the session manager of the edge node in the server device can construct a session service 322 corresponding to the target diagnostic service 332. The session service 322 can receive at least one diagnostic message corresponding to the diagnostic instruction 312, and then sort the at least one diagnostic message according to the order in which the diagnostic messages are received to obtain a message queue 2. Then, according to the message order of the message queue 2, the diagnostic messages in the message queue 2 are executed in sequence based on the target diagnostic service 332 to obtain a diagnostic result corresponding to the diagnostic instruction 312.

[0085] After receiving the diagnostic instruction 313 sent by the client device and determining that the diagnostic service identifier in the diagnostic instruction 313 corresponds to the requested target diagnostic service 333, the session manager of the edge node in the server device can construct a session service 323 corresponding to the target diagnostic service 333. The session service 323 can receive at least one diagnostic message corresponding to the diagnostic instruction 313, and then sort the at least one diagnostic message in the order in which the diagnostic messages are received to obtain a message queue 3. Then, according to the message order of the message queue 3, the diagnostic messages in the message queue 3 are executed in sequence based on the target diagnostic service 333 to obtain the diagnostic result corresponding to the diagnostic instruction 313.

[0086] Therefore, multiple independent diagnostic services can be set up in the server device, each diagnostic service can run independently, and multiple diagnostic services can perform diagnostic operations in parallel. Diagnostic operations are performed on the target diagnostic service corresponding to the diagnostic instruction to obtain diagnostic results, thereby realizing the modularization of the diagnostic service. The server device can execute multiple diagnostic instructions at the same time, thereby improving diagnostic efficiency, improving the scalability of the diagnostic service, and reducing the development difficulty and cost of the diagnostic service.

[0087] Figure 4 This is a flow chart of a vehicle diagnostic method provided by an embodiment of the present disclosure. The method can be executed by a server device disposed in a vehicle, such as Figure 4 As shown, the vehicle diagnostic method provided in this embodiment includes the following steps:

[0088] Step 410: In response to receiving at least one diagnostic instruction from the client device, obtain a diagnostic service identifier requested by each diagnostic instruction from the diagnostic instruction.

[0089] Step 420: Search for a target diagnostic service corresponding to each diagnostic service identifier from at least one preset diagnostic service. Each diagnostic service corresponds to a diagnostic service, and each diagnostic service processes the corresponding diagnostic service independently.

[0090] Step 430: For each target diagnostic service, obtain the working status of the target diagnostic service.

[0091] In the embodiment of the present disclosure, for each target diagnostic service, the edge node in the server device may obtain the working status of the target diagnostic service, and the working status may be a normal state or an abnormal state.

[0092] In some embodiments, the edge node in the server device may obtain heartbeat information generated by each target diagnostic service based on a heartbeat mechanism at preset intervals; and determine the working status of each target diagnostic service based on the heartbeat information.

[0093] The heartbeat mechanism can be understood as a command word for the device to automatically report its own status, and a mechanism for sending heartbeat information according to a certain waiting time.

[0094] The heartbeat information includes the working status of the diagnostic service.

[0095] Step 440: When the working state is normal, execute the corresponding diagnostic instruction based on the target diagnostic service and generate a diagnostic result.

[0096] Step 450: Forward the diagnostic results generated by each target diagnostic service to the client device.

[0097] Step 460: When the working state is an abnormal state, stop executing the corresponding diagnostic instruction based on the target diagnostic service, and send a second alarm message to the client device, where the second alarm message includes the abnormality of the target diagnostic service.

[0098] Therefore, multiple independent diagnostic services can be set up in the server-side device, each diagnostic service can run independently, and multiple diagnostic services can perform diagnostic operations in parallel. When the working status of the target diagnostic service corresponding to the diagnostic instruction is normal, the diagnostic operation is performed based on the target diagnostic service corresponding to the diagnostic instruction to obtain the diagnostic result, thereby realizing the modularization of the diagnostic service, allowing the server-side device to execute multiple diagnostic instructions at the same time, improving the diagnostic efficiency, and improving the scalability of the diagnostic service, reducing the development difficulty and development cost of the diagnostic service.

[0099] In some embodiments of the present disclosure, before searching for the target diagnostic service corresponding to each diagnostic service identifier from at least one preset diagnostic service, the server device can obtain a service registration request for the diagnostic service in response to the start of any diagnostic service among the at least one diagnostic service, where the service registration request includes at least the diagnostic service identifier and logical storage address of the diagnostic service; in response to the service registration request of the diagnostic service, the diagnostic service identifier and logical storage address of the diagnostic service can be stored in the service list, and the registration status of the diagnostic service can be adjusted to a successful registration status.

[0100] In this way, the diagnostic service can be registered to achieve functional expansion of the diagnostic service.

[0101] Figure 5 is a flow chart of a vehicle diagnostic method provided by an embodiment of the present disclosure, which can be executed by a client device, such as Figure 5 As shown, the vehicle diagnostic method provided in this embodiment includes the following steps:

[0102] Step 510: In response to a user's diagnostic operation on the vehicle, at least one diagnostic instruction corresponding to the diagnostic operation is generated, and each diagnostic instruction includes a diagnostic service identifier requested by the diagnostic instruction.

[0103] In an embodiment of the present disclosure, when a user needs to diagnose a vehicle, a diagnostic operation can be performed on a client device, such as a click operation on at least one target diagnostic service on the client device interface. The client device can generate at least one diagnostic instruction in response to the user's diagnostic operation, and each diagnostic instruction can include a diagnostic service identifier of the requested target diagnostic service.

[0104] Step 520: Send at least one diagnostic instruction to the server device so that the server device searches for a target diagnostic service corresponding to each diagnostic service identifier from at least one preset diagnostic service. For each diagnostic instruction, the server device executes the diagnostic instruction and generates a diagnostic result based on the target diagnostic service corresponding to the diagnostic service identifier in the diagnostic instruction. The server device is located in the vehicle, and each diagnostic service corresponds to a diagnostic business. Each diagnostic service processes the corresponding diagnostic business independently of each other.

[0105] In an embodiment of the present disclosure, after generating at least one diagnostic instruction, the client device can send at least one diagnostic instruction to the server device, so that the server device searches for the target diagnostic service corresponding to each diagnostic service identifier from at least one preset diagnostic service, and for each diagnostic instruction, executes the diagnostic instruction based on the target diagnostic service corresponding to the diagnostic service identifier in the diagnostic instruction and generates a diagnostic result.

[0106] The server device is located in the vehicle, each diagnostic service corresponds to a diagnostic business, and each diagnostic service processes the corresponding diagnostic business independently.

[0107] Step 530: Receive the diagnostic results generated by each target diagnostic service sent by the server device.

[0108] Therefore, multiple independent diagnostic services can be set up in the server-side device. Each diagnostic service can run independently, and multiple diagnostic services can perform diagnostic operations in parallel. Diagnostic operations are performed based on the target diagnostic service corresponding to the diagnostic instruction to obtain diagnostic results, thereby realizing the modularization of the diagnostic service. Multiple diagnostic instructions can be executed at the same time, thereby improving diagnostic efficiency. Moreover, when it is necessary to modify the diagnostic service or adjust and increase the function, it is only necessary to modify or adjust the corresponding diagnostic service. When it is necessary to expand the function of the diagnostic service, it is only necessary to add a diagnostic service with the corresponding function without modifying the existing diagnostic service program. This improves the scalability of the diagnostic service and reduces the development difficulty and development cost of the diagnostic service.

[0109] An embodiment of the present disclosure provides a vehicle diagnostic system, which may include a client device and a server device. The server device may include an edge node and at least one diagnostic service. Each diagnostic service corresponds to a diagnostic business, and each diagnostic service processes the corresponding diagnostic business independently.

[0110] Among them, the edge node can be used to respond to receiving at least one diagnostic instruction from a client device, obtain the diagnostic service identifier requested by the diagnostic instruction from each diagnostic instruction; search for the target diagnostic service corresponding to each diagnostic service identifier from at least one preset diagnostic service; for each diagnostic instruction, forward the diagnostic instruction to the corresponding target diagnostic service so that the target diagnostic service executes the diagnostic instruction and generates a diagnostic result; receive the diagnostic result sent by each target diagnostic service; and forward the diagnostic result generated by each target diagnostic service to the client device.

[0111] The client device can be used to generate at least one diagnostic instruction corresponding to the diagnostic operation in response to the user's diagnostic operation on the vehicle, each diagnostic instruction including a diagnostic service identifier requested by the diagnostic instruction; send at least one diagnostic instruction to the server device so that the server device searches for the target diagnostic service corresponding to each diagnostic service identifier from at least one preset diagnostic service, executes the corresponding diagnostic instruction based on the target diagnostic service and generates a diagnostic result; and receives the diagnostic result generated by each target diagnostic service sent by the server device.

[0112] For example, Figure 6 A structural diagram of a vehicle diagnostic system is provided.
