Description

Technical Field

[0001] The present invention relates to the technical field of vehicle information security, and particularly relates to a vehicle remote diagnosis method, device and computer-readable storage medium for after-sales scenarios. Background Art

[0002] In the scenario of remote diagnosis, since there is no direct physical connection with the target vehicle, but after querying the vehicle through the VIN code and initiating a connection, there is a risk of mistakenly entering the vehicle identification number (VIN) of other vehicles, resulting in misconnection to vehicles and disturbing users. At the same time, since the current state of the target vehicle is not directly observed, there is a risk that the user may mistakenly send a script containing intervention-type diagnostic services under inappropriate vehicle conditions (such as during driving), thus affecting vehicle safety.

[0003] Currently, some manufacturers, due to their inability to solve the problem of misusing data intervention-type instructions or diagnostic processes, adopt a solution of remotely disabling data intervention-type instructions or diagnostic processes. However, completely disabling the triggering ability of data intervention-type instructions or diagnostic processes for remote diagnosis will limit the manufacturer's ability to remotely solve problems. There are also some manufacturers who use an electronic fence solution to determine whether the vehicle terminal is within an authorized auto sales service store. If it is within the store, the personnel in the auto sales service store can put the vehicle into maintenance mode and use the APP on the vehicle console for diagnosis, but the remote diagnosis cloud platform is not open for the personnel in the auto sales service store to use, which will limit the ability of in-store operators to solve vehicle terminal software problems. Summary of the Invention

[0004] The technical problem to be solved by the embodiments of the present invention is to provide a vehicle remote diagnosis method, device and computer-readable storage medium for after-sales scenarios, so as to avoid the misconnection risk caused by the operator manually entering the VIN code and improve vehicle safety.

[0005] To solve the above technical problem, the present invention provides a vehicle remote diagnosis method for after-sales scenarios, which is characterized by including the following steps:

[0006] Receiving a remote diagnosis request sent by the vehicle terminal in the scenario where the vehicle has not arrived at the store;

[0007] Creating a remote diagnosis task for the target vehicle according to the remote diagnosis request;

[0021] The remote diagnosis after-sales application module verifies whether the current GPS positioning information of the target vehicle is within the electronic fence range of the reserved auto sales service shop; the electronic fence of the reserved auto sales service shop is generated by the remote diagnosis after-sales application module through the longitude and latitude information of the auto sales service shop;

[0022] If the target vehicle is within the electronic fence range, the remote diagnosis after-sales application module executes data intervention type diagnostic instructions on the target vehicle;

[0026] The remote diagnosis after-sales application module queries the vehicle manufacturer to which the vehicle model belongs through the "vehicle model - brand" correspondence table;

[0034] A remote diagnosis after-sales application module is used to create a remote diagnosis task for the target vehicle according to the remote diagnosis request; and determine whether the diagnostic instruction of the remote diagnosis task is a data intervention type diagnostic instruction or a non-data intervention type diagnostic instruction.

[0049] The following descriptions of each embodiment refer to the accompanying drawings to exemplify specific embodiments in which the present invention can be implemented.

[0050] Please refer to Figure 1 As shown, Embodiment 1 of the present invention provides a vehicle remote diagnosis method in a post - sales scenario, including the following steps:

[0051] Receive a remote diagnosis request sent by the vehicle end in a vehicle - not - arriving - at - store scenario;

[0052] Create a remote diagnosis task for the target vehicle according to the remote diagnosis request;

[0053] Judge whether the diagnosis instruction of the remote diagnosis task is a data - intervention - type diagnosis instruction or a non - data - intervention - type diagnosis instruction. If the diagnosis instruction is a data - intervention - type diagnosis instruction, then execute the diagnosis instruction anti - misusage verification mechanism.

[0054] As can be seen from the above steps, when creating and implementing a remote diagnosis task according to a remote diagnosis request initiated by the vehicle end in the embodiment of the present invention, the judgment of the nature of the diagnosis instruction is added. For diagnosis instructions of the data intervention type, it is necessary to execute the anti-misuse verification mechanism for diagnosis instructions, so as to reduce the risks generated by remotely using diagnosis instructions or diagnosis processes of the data intervention type without the customer's knowledge.

[0055] It can be understood that the remote diagnosis after-sales application module uses remote communication technology to send vehicle fault codes, operation guides or other relevant information to the vehicle owner or dealer-end device to achieve remote diagnosis and maintenance, and integrates functions such as vehicle management, fault diagnosis, and data analysis, supporting after-sales service personnel (including operators at the automotive sales service dealer end and technicians of vehicle manufacturers) to perform remote and real-time diagnosis and maintenance operations on the vehicle.

[0056] Specifically, in this embodiment, the vehicle end sending a remote diagnosis request includes the in-vehicle computer sending a remote diagnosis request or a mobile terminal (such as the vehicle owner's mobile phone) bound to the vehicle sending a remote diagnosis request. Due to the increasing development of the mobile Internet, it is relatively more common to send a remote diagnosis request through a mobile terminal. The following takes the example of sending a remote diagnosis request through the vehicle owner's mobile terminal for illustration.

[0057] The embodiment of the present invention divides the remote diagnosis scenario into the vehicle being in the store and not being in the store. In the scenario where the vehicle is in the store, the remote diagnosis after-sales application module obtains the vehicle VIN code through the work order created by the work order system to generate a remote diagnosis task for the vehicle, avoiding incorrect vehicle connection caused by manual input of the wrong VIN code by the staff; in the scenario where the vehicle is not in the store, the remote diagnosis after-sales application module automatically creates a remote diagnosis task according to the remote diagnosis request sent by the vehicle end, also avoiding incorrect vehicle connection.

[0058] As Figure 2 shown, in the scenario where the vehicle is in the store, after the vehicle owner sends a remote diagnosis request (such as usually a reservation for vehicle maintenance and repair application) through the owner application installed on the mobile terminal, the vehicle owner drives the vehicle to the store. After the vehicle arrives at the store, the staff at the automotive sales service dealer end generates a repair work order through the work order system; the remote diagnosis after-sales application module obtains the VIN code of the vehicle through the work order created by the work order system and generates a remote diagnosis task for the vehicle. In this way, the operator at the dealer end can only perform remote diagnosis on the vehicle through this remote diagnosis task, thus avoiding incorrect vehicle connection caused by manual input of the wrong VIN code.

[0059] It is understandable that the remote diagnostic after-sales application module interfaces with the work order system of the vehicle manufacturer for the automotive sales service store to obtain the vehicle VIN code and other relevant vehicle information, and creates a remote diagnostic task based on this. Specifically, the VIN code of the target vehicle that needs to perform remote diagnosis is transmitted through the work order system. The remote diagnostic after-sales application module analyzes the vehicle model of the target vehicle through the obtained vehicle VIN code to obtain the vehicle model information of the target vehicle, and then queries the vehicle manufacturer to which the model belongs through the "model - brand" correspondence table; the remote diagnostic after-sales application module then sets the available account range for the remote diagnostic task of the vehicle according to the vehicle manufacturer to which the target vehicle belongs obtained by querying; finally, the remote diagnostic after-sales application module generates a to-be-processed remote diagnostic task according to the obtained VIN code of the target vehicle in accordance with the corresponding available account range and adds it to the remote diagnostic task pool.

[0060] For another example Figure 3 As shown, in the scenario where the vehicle has not arrived at the store, the vehicle owner sends a remote diagnostic request (such as usually a remote maintenance application) through the vehicle owner application installed on the mobile terminal. The back-end customer service staff of the remote diagnostic after-sales application module uses methods such as phone calls to confirm information with the vehicle owner according to the vehicle and vehicle owner contact information included in the remote maintenance application. If the confirmation is correct, a remote diagnostic task is automatically created according to the information of the remote maintenance application; then the remote diagnostic task is pushed to the task pool of the remote diagnostic after-sales application module of the corresponding automotive sales service store operator or the vehicle manufacturer's technical staff, thus avoiding the scenario of misconnection. If it is confirmed that the remote maintenance application is incorrect (such as being accidentally triggered by the vehicle owner), the remote maintenance application will be directly closed. Similarly, it is understandable that the vehicle owner mobile terminal application server interfaces with the remote diagnostic after-sales application module, enabling the vehicle owner to initiate a remote maintenance application through the vehicle owner mobile terminal, transmit relevant vehicle information to the remote diagnostic after-sales application module, and generate a remote diagnostic task. The corresponding application dispatching process is set in the remote diagnostic after-sales application module to enable the vehicle manufacturer's customer service staff to push the remote diagnostic application to the remote diagnostic after-sales application module account of the corresponding vehicle manufacturer's technical staff or automotive sales service store operator after confirming the vehicle owner's vehicle information, generating a remote diagnostic task and adding it to the task pool.

[0061] Through the above process, the problem of vehicle misconnection during remote diagnosis is solved, providing a correct basis for the next step of implementing specific diagnostic operations and preventing misuse.

[0062] As described above, there is currently a problem of misusing data intervention instructions or diagnostic processes, posing a severe challenge to vehicle safety. When a remote diagnostic task is created and the remote diagnostic operator performs remote diagnosis, if the operation of the remote diagnostic operator involves triggering a data intervention diagnostic instruction, the embodiment of the present invention will trigger a corresponding anti-misuse verification mechanism according to the actual situation. It can be understood that, based on whether the service instruction will affect the operation of some functions of the entire vehicle and whether it will intervene in vehicle data, the remote diagnostic instructions are classified into data intervention diagnostic instructions and non-data intervention diagnostic instructions.

[0063] The distinction between data intervention diagnostic instructions and non-data intervention diagnostic instructions can be achieved by adding identification parameters in the remote diagnostic after-sales application module. The identification parameters are usually one or more specific identifiers or flag bits, used to clearly indicate whether a diagnostic service involves intervention or modification at the data level. Specific examples of identification parameters are as follows:

[0064] Intervention flag bit: This is a binary parameter used to identify whether a diagnostic service involves data intervention. For example, when the value is "1", it indicates data intervention, and when it is "0", it indicates no data intervention.

[0065] Service type parameter: This is an enumerated type parameter, and its different values correspond to different diagnostic service types. For example, the values may be "intervention" and "non-intervention", or more detailed classifications.

[0066] Data field identifier: In some cases, a specific data field in the diagnostic instruction can indicate whether data intervention has been performed. For example, a specific field or field combination in the instruction identifies the data modification operation.

[0067] When the remote diagnostic after-sales application module receives a diagnostic service request, it will check these identification parameters to determine the type of diagnostic service requested. Based on the values of these parameters, the remote diagnostic after-sales application module can decide whether to perform further data intervention operations or execute a non-intervention diagnostic process.

[0068] For the vehicle-side anti-misuse of data intervention diagnostic instructions:

[0069] First, it is necessary to determine whether there is permission to execute data intervention diagnostic instructions on the vehicle side.

[0070] Please refer to Figure 4 As shown, in the scenario where the vehicle has not arrived at the store as described above, the embodiment of the present invention uses owner authorization to achieve:

[0071] ①In the scenario where the vehicle has not arrived at the store, when a remote diagnosis operator needs to execute a data intervention type diagnosis instruction or diagnosis process on the vehicle, the remote diagnosis after-sales application module will initiate a data intervention authorization application through the owner's mobile terminal application of the target vehicle;

[0072] ②If the vehicle owner agrees to the data intervention authorization application, the remote diagnosis after-sales application module will continue to execute the data intervention type diagnosis instruction or diagnosis process on the vehicle; otherwise, it will terminate the execution of this type of instruction or process and prompt the operator.

[0073] Through the above authorization mechanism, the risks generated by using such diagnosis instructions or processes when the vehicle owner is using the vehicle can be reduced, as well as the risk of legal disputes caused by modifying vehicle data without the vehicle owner's knowledge, etc.

[0074] Please refer to again Figure 5 As shown, in the aforementioned scenario where the vehicle arrives at the store, the embodiment of the present invention uses electronic fence protection to achieve:

[0075] ①The remote diagnosis after-sales application module generates an electronic fence through the longitude and latitude information of the automobile sales service store;

[0076] ②In the scenario where the vehicle arrives at the store, when a remote diagnosis operator needs to execute a data intervention type instruction or diagnosis process on the vehicle, the remote diagnosis after-sales application module will check whether the current GPS positioning information of the vehicle is within the electronic fence range of the reserved automobile sales service store;

[0077] ③If the target vehicle is within the electronic fence range, the remote diagnosis after-sales application module will continue to execute the data intervention type instruction or diagnosis process on the vehicle; when the target vehicle is not within the electronic fence range, the remote diagnosis after-sales application module will call the interface provided by the vehicle owner's mobile terminal application server to send an authorization application. When the remote diagnosis after-sales application module obtains the response parameter indicating that the authorization application is passed, it will allow the invocation of the remote service with intervention; otherwise, it will terminate the execution of this type of instruction or process and prompt the operator.

[0078] Through the electronic fence, it can be effectively determined whether the vehicle is within the area suitable for carrying out remote diagnosis, reducing the secondary risks generated by performing remote diagnosis in an inappropriate area.

[0079] Secondly, it is necessary to determine whether the current vehicle meets the conditions for executing the data intervention type diagnosis instruction.

[0080] Please refer to Figure 6As shown, when a data intervention instruction is sent to the vehicle side for execution, the cloud will synchronously send the pre-execution conditions required for this service to the vehicle-side node of remote diagnosis (i.e., the vehicle-side diagnostic engine, such as the central control unit CCU). The pre-execution conditions for judging the vehicle condition, such as vehicle speed, vehicle mode, battery power, etc., will vary according to different vehicles and diagnostic instructions. The following are some specific examples listed exemplarily to illustrate the pre-execution conditions:

[0081] (1) Vehicle speed condition:

[0082] Stationary state: Some diagnostic instructions may require the vehicle to be in a stationary state to ensure the safety and accuracy of operations. For example, when an intervention instruction involving the vehicle's power system or transmission system needs to be executed, the vehicle speed is required to be 0 km / h.

[0083] Low-speed driving: Some instructions may be safely executed when driving at low speed. For example, when the vehicle speed is below 5 km / h, diagnostic instructions for wheel alignment adjustment or suspension system calibration can be executed.

[0084] (2) Vehicle mode condition:

[0085] Parking mode: Some diagnostic instructions may require the vehicle to be in the parking mode to ensure vehicle stability and reduce interference. For example, when diagnosing the vehicle's electronic stability program, the vehicle should be in the parking mode.

[0086] Electric mode: For electric vehicles, the vehicle may need to be in the electric mode (rather than the hybrid mode or fuel mode) to execute diagnostic instructions related to the motor, battery, etc.

[0087] (3) Battery power condition:

[0088] Minimum battery power threshold: Executing some data intervention diagnostic instructions may require the vehicle's battery power to be higher than a certain threshold to ensure that the instruction execution will not be interrupted due to insufficient power. For example, the power should be higher than 20% to execute diagnostic instructions related to the air conditioning system.

[0089] Sufficient battery power: Some complex diagnostic instructions may require longer execution time and higher battery power. For example, performing a comprehensive battery health diagnosis may require the battery power to be above 80%.

[0090] The above conditions are only examples and are not generally applicable to all vehicles and diagnostic instructions. The actual conditions may vary depending on the vehicle model, manufacturer requirements, and characteristics of the diagnostic instructions.

[0091] ① After the data intervention diagnostic instruction is sent to the vehicle side, the vehicle-side node of remote diagnosis will obtain the current various states of the target vehicle;

[0092] ②The vehicle - end node for remote diagnosis compares the pre - execution conditions of the data intervention - type instructions with the corresponding status of the target vehicle to determine whether the target vehicle meets the pre - execution conditions of the data intervention - type instructions;

[0093] ③If it meets the conditions, the vehicle - end node for remote diagnosis will execute the data intervention - type diagnostic instruction; if it does not meet the conditions, it will feedback the reason for inability to execute to the remote diagnosis after - sales application module, thus avoiding using the data intervention - type diagnostic instruction at the wrong time and causing unpredictable risks.

[0094] In addition, as Figure 7 shown, considering that if an operator with less experience performs remote diagnosis operations, the embodiment of the present invention also sets up an intelligent diagnosis constraint usage instruction protection mechanism to prevent misuse:

[0095] ①When the operator performs remote diagnosis, the intelligent diagnosis analysis platform is retrieved through the remote diagnosis after - sales application module to analyze the faults of the current vehicle and generate a fault troubleshooting guide;

[0096] ②The operator can directly trigger the corresponding diagnostic instruction or diagnostic process through the relevant troubleshooting steps in the fault troubleshooting guide. At the same time, the operator can only perform remote diagnosis operations according to the fault troubleshooting guide, thus avoiding performing remote diagnosis operations that do not need to be executed and reducing the probability of risks caused by performing incorrect remote diagnosis operations due to lack of experience.

[0097] The above - mentioned intelligent diagnosis constraint usage instruction protection mechanism is more friendly to remote diagnosis operators with less experience, making the troubleshooting of problems more directional. While improving the troubleshooting efficiency, it reduces the additional risks brought by using unnecessary diagnostic instructions or processes.

If the diagnostic instruction is a data intervention - type diagnostic instruction, then execute the diagnostic instruction anti - misuse verification mechanism.

[0106] Preferably, the computer program can be divided into one or more modules / units (such as computer program 1, computer program 2,...), and the one or more modules / units are stored in the memory and executed by the processor to complete the present invention. The one or more modules / units can be a series of computer program instruction segments capable of performing specific functions, and these instruction segments are used to describe the execution process of the computer program in the device.

The processor is the control center of the device, and connects various parts of the device through various interfaces and lines.

[0108] The memory mainly includes a program storage area and a data storage area. Among them, the program storage area can store the operating system, application programs required for at least one function, etc., and the data storage area can store relevant data, etc. In addition, the memory can be a high-speed random access memory, or a non-volatile memory, such as a plug-in hard disk, a SmartMedia Card (SMC), a Secure Digital (SD) card, a Flash Card, etc., or the memory can also be other volatile solid-state storage devices.

[0109] It should be noted that the above device may include but is not limited to a processor and a memory, which can be understood by those skilled in the art.

For diagnosis instructions of the data intervention type, a diagnosis instruction anti-misuse verification mechanism needs to be executed, reducing the risk generated by remotely using diagnosis instructions or diagnosis processes of the data intervention type without the customer's knowledge; by judging the pre-execution conditions of the diagnosis instruction or diagnosis process under the current vehicle condition by the vehicle terminal node of the remote diagnosis, the probability of the risk generated by executing inappropriate diagnosis instructions or diagnosis processes under the wrong vehicle condition is greatly reduced; during the entire process from initiating an application to generating a task for remote diagnosis, there is no need to manually input the VIN code, reducing the risk of vehicle connection failure or connection error caused by entering the VIN code incorrectly; through the electronic fence, it can effectively determine whether the vehicle is within the area suitable for remote diagnosis, reducing the secondary risk generated by performing remote diagnosis in an inappropriate area.
