[0002] The on-board diagnostics (OBD) system is a vehicle-based diagnostic information exchange platform that monitors in real time whether a vehicle has experienced any faults during use. Its purpose is to provide platform-based technical means for fault acquisition, function configuration, routine execution, and software refresh for automotive companies' engineering development, production line testing, and after-sales service. Traditional vehicle diagnostic technology uses an operator-diagnostic tool-vehicle interaction model. When a vehicle needs to be diagnosed after sales, the operator needs to connect the after-sales tool to the vehicle's OBD port one by one to read the fault information and vehicle data before performing a diagnosis. If there are many vehicles, users need to queue for diagnosis, which consumes a lot of manpower and resources, and has low diagnostic efficiency and user experience. During off-line diagnosis in a manufacturing plant, the off-line testing operator is also required to connect the diagnostic equipment to the vehicle's OBD port to read the diagnostic data and perform the diagnosis. This also consumes a lot of manpower and resources, and has low diagnostic efficiency. Summary of the Invention

For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0049] Traditional vehicle diagnostic technology uses an interactive model involving operator, diagnostic tool, and vehicle. When a vehicle requires after-sales diagnosis, an operator must connect the after-sales tool to the vehicle's OBD port one by one to read the vehicle's data and perform a diagnosis. This, combined with the large number of vehicles, requires users to queue for diagnosis, consuming significant manpower and resources, and resulting in low diagnostic efficiency and user experience. During end-of-line diagnosis at the manufacturing plant, an operator must also connect the diagnostic equipment to the vehicle's OBD port to read and diagnose the fault. This, too, consumes significant manpower and resources, and results in low diagnostic efficiency.

[0050] The main application scenarios of diagnosis are after-sales and production lines. In the era of intelligent networking, the technological development of cloud diagnosis has realized the expansion of diagnostic interaction methods from local to cloud. However, the application of after-sales production line diagnosis still has the following problems to be solved, such as high operating costs, low maintenance efficiency, and after-sales tools relying on staff operation. The embodiment of the present invention supplements the current diagnostic interaction method. On the basis of the basic functions of the existing diagnostic system such as protocols, services, and data, it utilizes the computing and storage capabilities of the vehicle domain controller, integrates Ethernet diagnostic technology, wireless local area networking technology, Internet artificial intelligence / big data technology, data sharing technology, etc. to realize the vehicle-to-vehicle networking of diagnostic technology.

[0051] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0052] Please refer to Figure 1(a), which is a flow chart of a self-service on-board diagnostic interaction method based on a mobile ad hoc network disclosed in an embodiment of the present invention. In this case, the ad hoc network adopts an ad-hoc mode. The self-service on-board diagnostic interaction method includes:

[0053] Step S10: The first target vehicle enters the target area covered by the Ad-hoc network and joins the Ad-hoc network after identity authentication.

[0054] Specifically, in some embodiments of the present invention, the networking technology uses a point-to-point wireless mobile network Ad-hoc, with each vehicle's diagnostic edge node serving as a network access point to support application layer modules such as Dynamic Host Configuration Protocol (DHCP), Ethernet diagnostic technology DoIP, and wireless local area network (WLAN) management. The transport layer supports transport layer protocols (Transmission Control Protocol (TCP) and User Datagram Protocol (UDP)) in wireless environments for process communication, and the network layer supports wireless dynamic routing protocols. Each vehicle joining the Ad-hoc network has equal status, eliminating the need for a central control node. After entering an area covered by the Ad-hoc network, vehicles can quickly join and freely leave the Ad-hoc network. Vehicles joining the Ad-hoc network have the functions required by mobile terminals and also have message forwarding capabilities, enabling forwarding routing and expanding the coverage of the Ad-hoc network. The diagnostic edge node is a gateway node for vehicle-to-external communication, enabling vehicle-to-external communication and effectively isolating the internal and external networks of the vehicle. It serves as the entry point for external wired or wireless devices to access the vehicle. When implementing forwarding routing, the Ad-hoc node acts as a relay node, receives information from node A as a diagnostic edge node, and forwards it to node B as a diagnostic edge node through multi-hop routing. The diagnostic edge nodes where each Ad-hoc node is located all support the routing algorithm.

[0055] Furthermore, in some embodiments of the present invention, the first target vehicle refers to a vehicle that first enters a target area covered by the Ad-hoc network at a certain moment, and the authentication of the first target vehicle may be wireless authentication of the first target vehicle. The wireless authentication of the first target vehicle is performed based on a PKI certificate (including signature verification and other processes).

[0056] Furthermore, in some embodiments of the present invention, for each vehicle that enters the Ad-hoc network and requires diagnostic services, the diagnostic edge node of each vehicle can implement online Ethernet diagnosis and passive receiving processing through the diagnostic matrix.

[0057] To achieve the above objectives, on the one hand, each vehicle should support an Ethernet diagnostic client (OEM custom function), support the function of an Ethernet online diagnostic tool, and support data scripts, data loading, and the sending and receiving of diagnostic service requests, so as to control various bus nodes in the vehicle (such as CAN bus nodes, CANFD bus nodes, Ethernet bus nodes) to perform diagnostic tasks. Among them, the online diagnostic tool (as opposed to the offline tool that is locally connected to the OBD port) is integrated into the edge node, and the diagnostic protocol uses the Ethernet diagnostic protocol. On the other hand, it should also support the Ethernet diagnostic server to assist in vehicle communication connection, vehicle identification, route activation, and receiving and processing task instructions from other vehicle diagnostic edge nodes, and sending and receiving shared data. Among them, vehicle communication connection, vehicle identification and route activation are implemented based on the Ethernet diagnostic DoIP protocol.

[0058] Step S11: the first target vehicle broadcasts a first diagnostic request, which carries the configuration data of the first target vehicle and the first service code of the application service package.

[0059] Specifically, in some embodiments of the present invention, after the first target vehicle enters the Ad-hoc network, the user can choose whether to perform a diagnosis on the human-computer interaction interface in the vehicle. If the user chooses to perform a diagnosis in the vehicle, the first target vehicle broadcasts a first diagnostic request through the Ad-hoc network. The first diagnostic request is issued by the on-board diagnostic system, which is generated by the vehicle Ethernet diagnostic client of the first target vehicle through the comparison of the vehicle version information, vehicle model and configuration list (configuration data) to generate a first service code. Applying for a service package refers to the user applying for service data corresponding to the first service code from the diagnostic data platform or other vehicles that have joined the Ad-hoc network. The configuration list refers to the engine type, transmission type, and whether automatic parking is available.

[0060] Specifically, in some embodiments of the present invention, the first target vehicle may adopt UDP broadcasting when broadcasting the first diagnostic request.

[0061] Step S12: The diagnostic data platform center provides target data matching the first business code for the first target vehicle.

[0062] Specifically, in some embodiments of the present invention, the physical network of the diagnostic edge node of the first target vehicle is connected to each diagnostic node in the vehicle of the first target vehicle. The diagnostic edge node has the function of centralized management of diagnostic tasks. When the first target vehicle receives the target data sent by the diagnostic data platform and the diagnostic task corresponding to the first diagnostic request, it controls each controller connected to the diagnostic edge node through task parallel scheduling and data broadcasting to implement the software centralized control upgrade function technical configuration, etc., wherein the software centralized control upgrade function technical configuration refers to the unified process management of the in-vehicle controllers through the edge node, i.e., the gateway, to achieve concurrent diagnostic execution. In this way, the first target vehicle does not need to interact with the outside world for diagnosis. The diagnostic edge node, as the only access point connected to the outside world, uses WLAN technology to achieve isolation between the diagnostic intranet and the external network. Centralized control of concurrent execution can also improve the execution efficiency of diagnostic tasks.

[0063] Specifically, in some embodiments of the present invention, the first target vehicle communicates with the diagnostic data platform center via the TCP protocol.

[0064] Step S13: The diagnostic application platform provides diagnostic services to the first target vehicle based on the target data and feeds back the diagnostic results to the first target vehicle.

[0065] Specifically, in some embodiments of the present invention, the diagnostic application platform is used to perform diagnostic tasks, the collection, judgment and decision-making of diagnostic data (target data), including target data sharing domain management, data mining, diagnostic task interaction functions, centralized control, diagnostic decision-making and fault prediction functions. After the diagnostic application platform completes the diagnostic task, the diagnostic application platform will automatically exit the current Ad-hoc network, and will not affect the communication of other nodes in the network due to changes in the network topology, nor will it affect the communication performance of the Ad-hoc network. Specifically, the diagnostic application platform can receive and initiate the execution of diagnostic tasks and collect diagnostic responses. The diagnostic application platform integrates modular diagnostic tools, and the address information of the target diagnostic object (the first target vehicle) can be known by loading and parsing tasks. Diagnostic tasks include but are not limited to refresh tasks, configuration tasks, calibration tasks and fault detection tasks. When the diagnostic application platform performs diagnostic tasks, it can perform diagnostic tasks through a variety of technologies such as diagnostic communication protocols, diagnostic service protocols, machine learning, data models, data storage management, etc.

[0066] The embodiment of the present invention discloses a self-service on-board diagnostic interaction method based on a mobile self-organizing network. When a first target vehicle needs to undergo vehicle diagnosis, as long as the first target vehicle joins the Ad-hoc network, the first target vehicle can issue a first diagnostic request. The diagnostic data platform center can provide matching target data for the service code of the first diagnostic request. The diagnostic application platform can complete the diagnostic service for the first target vehicle based on the target data and feed back the diagnostic results to the first target vehicle. This eliminates the need for vehicle drivers to wait in line for long periods of time, improving the user experience. At the same time, as long as the vehicles join the Ad-hoc network, the diagnostic data platform and the diagnostic application platform can provide diagnostic services to multiple vehicles simultaneously, improving the efficiency of vehicle diagnosis and avoiding the waste of manpower and material resources.

[0067] That is, when a vehicle requires after-sales software upgrades, configurations, matching, and fault diagnosis, as shown in Figure 1(b), each vehicle can autonomously join an Ad-hoc network (which can provide a software upgrade network, a terminal learning network, and a fault repair network) to meet its diagnostic needs. Users no longer need to wait in line for after-sales operators to use diagnostic tools (where the data platform can provide data support for each network) for diagnosis. Instead, users can autonomously operate the human-computer interaction interface to apply for a service package and initiate diagnostic interaction. After the diagnostic task is completed, they can confirm the diagnostic results through a self-test program, pay a self-service fee, and then leave the self-organizing network environment. The self-test program refers to the process of sending diagnostic instructions through the diagnostic application platform to trigger the automatic execution of programs in various systems within the vehicle, simulate functional operation, or read related parameters to understand the diagnostic results. In addition, when a vehicle is undergoing dynamic offline testing on a production line, the offline testing vehicles can be added to the Ad-hoc network to establish a dynamic production line. Each vehicle, based on its own model and configuration list, requests test data from the offline testing data platform in the dynamic production line network, achieving offline testing and improving diagnostic efficiency.

[0068] Please refer to Figures 2(a) and 2(b). Figure 2(a) is a flow chart of another self-service on-board diagnostic interaction method based on a mobile self-organizing network disclosed in an embodiment of the present invention, and Figure 2(b) is a specific implementation flow chart of an on-board diagnostic interaction based on a mobile self-organizing network disclosed in an embodiment of the present invention. Among them, the self-organizing network adopts the Ad-hoc mode. After the first target vehicle joins the Ad-hoc network, when the second target vehicle continues to join the Ad-hoc network, the second target vehicle can request target data from the diagnostic data platform center in the same way as the first target vehicle. The second target vehicle can also send a sharing request to the first target vehicle, and the first target vehicle will share the data. As shown in Figures 2(a) and 2(b), the self-service on-board diagnostic interaction method includes:

[0069] Step S10: The first target vehicle (such as the replacement vehicle 3 shown in FIG2(b)) enters the target area covered by the Ad-hoc network (such as the self-service area shown in FIG2(b)) and joins the Ad-hoc network after identity authentication.

[0070] Step S11: the first target vehicle broadcasts a first diagnostic request, which carries the configuration data of the first target vehicle and the first service code of the application service package.

[0071] Step S12: The diagnostic data platform center provides target data matching the first business code for the first target vehicle.

[0072] Step S13: The diagnostic application platform provides diagnostic services to the first target vehicle based on the target data and feeds back the diagnostic results to the first target vehicle.

[0073] Step S14: the second target vehicle added to the Ad-hoc network broadcasts a second diagnostic request, where the second diagnostic request carries the configuration data of the second target vehicle and the second service code of the application service package.

[0074] Step S15: The first target vehicle responds to the second diagnosis request and shares target data with the second target vehicle (the same-code service package shown in FIG2( b )).

[0075] Specifically, in some embodiments of the present invention, in order to share data with other vehicles, the diagnostic edge node of each vehicle can be specially set up with a data sharing area of ​​the target area size for receiving and sending shared target data. The external storage of the data sharing area should be isolated for internal use to prevent disguised data storage and damage to other vehicle data.

[0076] Furthermore, in some embodiments of the present invention, when the first target vehicle and the second target vehicle share target data, the edge diagnostic nodes of the first target vehicle and the second target vehicle have built-in security chips, and the target data is encrypted for transmission and signature authentication based on the Public Key Infrastructure (PKI) / CA mechanism, and two-way security authentication is performed before diagnostic interaction with other vehicles in the self-organizing network.

[0077] Furthermore, in some embodiments of the present invention, a DANET network may be used to perform security authentication and wireless communication between the first target vehicle and the second target vehicle, including self-organizing networking, vehicle scanning, data exchange, information security, and necessary configuration, error handling, and human-computer interaction. The data exchange function refers to the data sharing function, information security (such as identity authentication and data message encryption), and error handling refers to the fault-tolerant strategy in abnormal scenarios (such as requesting retransmission after data reception is interrupted, resuming transmission at a breakpoint, and restarting software after a software error occurs).

[0078] Furthermore, the network kernel part of the first target vehicle and the second target vehicle can be used to provide a communication protocol stack, including transport layer / network layer protocols, on-demand distance vector routing protocols, data link layer / physical layer protocols, and wireless network card hardware drivers, etc.

[0079] Step S16: The diagnostic application platform provides diagnostic services to the second target vehicle according to the target number and feeds back the diagnostic results to the second target vehicle.

[0080] The first service code and the second service code are the same.

[0081] Step S17: The first target vehicle and the second target vehicle store the target data according to the target data storage structure and the storage overflow mechanism.

[0082] Specifically, in some embodiments of the present invention, the diagnostic edge nodes of the first target vehicle and the second target vehicle can store target data (derived from the shared data of the diagnostic data platform center or other vehicles). For the diagnostic edge nodes, after obtaining the target data (fault parameters, operating data), the target data can be mined and machine-learned to optimize its own fault detection and prediction model. Among them, fault parameters include but are not limited to fault codes, fault auxiliary information, etc., and operating data include but are not limited to circuit open / short circuit status, network status, etc. For the fault detection and prediction model, it refers to classifying the data according to the data mining algorithm (such as the neural network algorithm) to obtain the parameter model when the fault occurs.

[0083] S18: After the first target vehicle and the second target vehicle complete the diagnosis, the first target vehicle and the second target vehicle exit the Ad-hoc network.

[0084] The embodiment of the present invention discloses a self-service on-board diagnostic interaction method based on a mobile self-organizing network. When a first target vehicle needs to undergo vehicle diagnosis, as long as the first target vehicle joins the Ad-hoc network, the first target vehicle can issue a first diagnostic request. The diagnostic data platform center can provide matching target data for the service code of the first diagnostic request. The diagnostic application platform can complete the diagnostic service for the first target vehicle based on the target data and feed back the diagnostic results to the first target vehicle. This eliminates the need for vehicle drivers to wait in line for long periods of time, improving the user experience. At the same time, as long as the vehicles join the Ad-hoc network, the diagnostic data platform and the diagnostic application platform can provide diagnostic services to multiple vehicles simultaneously, improving the efficiency of vehicle diagnosis and avoiding the waste of manpower and material resources.

[0085] In addition, by enabling vehicle users to share data between vehicles in any environment, in a safe driving mode, and within the distance allowed by the self-organizing network, diagnostic interaction functions can be achieved, and target data of similar businesses can be shared or failure-related operating parameters can be compared and calibrated, as well as difference reminders can be provided, to achieve experience-based fault prediction.

[0086] See below Figure 3 , Figure 3 This is a schematic diagram of the structure of a self-service on-board diagnostic interactive system based on a mobile ad hoc network disclosed in an embodiment of the present invention, including:

[0087] Target vehicles 40, the target vehicles 40 are objects to be diagnosed, and the target vehicles 40 are interconnected via an Ad-hoc network;

[0088] The diagnostic data platform center 41 provides the target vehicle 40 with target data that matches the target vehicle's business code;

[0089] The diagnostic application platform 42 is used to provide diagnostic services to the target vehicle 40 based on the target data and feed back the diagnostic results to the target vehicle 40 .

[0090] In addition, an embodiment of the present invention further discloses a car, including the above-mentioned self-service on-board diagnostic interactive system based on a mobile ad hoc network.

[0091] The embodiment of the present invention discloses a self-service on-board diagnostic interactive system based on a mobile self-organizing network. When a first target vehicle needs to undergo vehicle diagnosis, as long as the first target vehicle joins the Ad-hoc network, the first target vehicle can issue a first diagnostic request. The diagnostic data platform center can provide matching target data for the service code of the first diagnostic request. The diagnostic application platform can then complete the diagnostic service for the first target vehicle based on the target data and feed back the diagnostic results to the first target vehicle. This eliminates the need for vehicle drivers to wait in line for long periods of time, improving the user experience. At the same time, as long as the vehicles join the Ad-hoc network, the diagnostic data platform and the diagnostic application platform can provide diagnostic services to multiple vehicles simultaneously, improving the efficiency of vehicle diagnosis and avoiding waste of manpower and material resources.
