On the contrary, the embodiments of the present application can be applied to any applicable scenario.

[0048] The present application also proposes a method and device for detecting vehicle faults, an electronic device and a medium.

[0049] Figure 1 A flowchart of a method for detecting vehicle faults according to an embodiment of the present application is schematically shown. As Figure 1 shown, the method is applied to a vehicle terminal and includes the following steps.

[0050] S101, receiving an access request sent by a vehicle terminal to be detected, the access request carrying an access transmission protocol corresponding to the vehicle terminal to be detected.

[0051] S102, if it is determined that the security verification of the vehicle terminal to be detected is passed, selecting a fault detection model matched with the access transmission protocol.

[0052] S103, receiving vehicle data uploaded by the vehicle terminal to be detected through the access transmission protocol, and transmitting the vehicle data to the fault detection model to obtain an identification result of the vehicle terminal to be detected.

[0053] With the rapid development of the domestic economy, the automobile industry is also becoming more and more developed. Among them, improving the automatic processing flow of the safety monitoring of the automobile is the goal pursued by the safety monitoring server.

[0054] In the related art, the safety monitoring service of the vehicle is generally deployed in a corresponding alarm processing mode for the vehicles in a certain area (for example, a certain city). This kind of mode can only access the vehicle parameters of the safety protocol standard required by the area. However, when deploying the alarm processing mode corresponding to the areas of multiple different safety standards, a large amount of development resources will be consumed, and the cost of the operation platform is increased.

[0055] Further, in order to solve the above-mentioned problems, the present application provides a method for detecting vehicle faults, which is used to solve the problem of consuming operation cost caused by deploying safety monitoring servers for areas of multiple different safety standards in the related art.

[0056] Specifically, after receiving access requests from various vehicle terminals under test, the security operations platform can parse the access transmission protocol corresponding to the vehicle terminal under test carried in the access request, and then select a fault detection model that matches the access transmission protocol from a preset model library.

[0057] Understandably, the model library can store fault detection models corresponding to each data transmission protocol. That is, each fault detection model is used to detect vehicle data under a specific access transmission protocol, thereby identifying whether there are any fault events in the vehicle under that access transmission protocol.

[0058] In one embodiment, the access transmission protocol can be the 808 protocol. Additionally, after receiving the access request sent by the vehicle terminal under test, this application can also perform multiple access condition checks on the vehicle terminal under test, such as device connectivity detection, model detection, encoding detection, signal detection, and protocol detection, etc.

[0059] Understandably, only after the safety operation platform determines that one or more access conditions of the vehicle terminal have passed the detection can the subsequent steps of selecting a fault detection model that matches the access transmission protocol be implemented.

[0060] Furthermore, after matching the fault detection model according to the terminal's access transmission protocol, the fault detection model can be decomposed according to the data source type of the vehicle data, so that each decomposed detection model detects its own factors and then the multiple sub-identification results are aggregated to obtain the aggregated total identification result.

[0061] Among them, such as Figure 2 As shown, each decomposition detection model is used to identify vehicle data of a specific data source type. For example, data source types may include manual alarms, area alerts, restricted driving time alerts, route deviation alerts, speeding alerts, fatigue driving alerts, low battery alerts, power outage alerts, antenna disconnection alerts, overtime parking alerts, terminal malfunction alerts, abnormal tire pressure alerts, collision alerts, rollover alerts, unsafe driving behavior alerts, right turn blind spot alerts, and so on.

[0062] In the present application, the access request sent by the vehicle terminal to be detected can be received, and the access transmission protocol corresponding to the vehicle terminal to be detected is carried in the access request. If it is determined that the security verification of the vehicle terminal to be detected is passed, a fault detection model matched with the access transmission protocol is selected. The vehicle data uploaded by the vehicle terminal to be detected is received through the access transmission protocol, and the vehicle data is transmitted to the fault detection model to obtain the identification result of the vehicle terminal to be detected. By applying the technical solution of the present application, after the access request uploaded by the vehicle terminal is obtained, and after it is determined that the security verification is passed, the fault detection model matched with the protocol can be automatically selected according to the subsequent uploaded vehicle data to identify whether the vehicle has a fault event, so as to realize the automatic processing of the automobile safety fault monitoring. Therefore, the problem of high operating cost caused by deploying safety monitoring servers for multiple different safety standards in the related art is solved.

[0063] Optionally, in another embodiment based on the above method of the present application, after receiving the access request sent by the vehicle terminal to be detected, the method further comprises:

[0064] The access condition detection of the vehicle terminal to be detected includes at least one of device connection detection, model detection, code detection, signal detection and protocol detection;

[0065] If it is determined that the access condition detection is passed, it is determined that the security verification of the vehicle terminal to be detected is passed.

[0066] Optionally, in another embodiment based on the above method of the present application, after receiving the access request sent by the vehicle terminal to be detected, the method further comprises:

[0067] A vehicle owner verification request is generated, and the vehicle owner verification request is used to obtain the biological feature information of the vehicle owner user using the vehicle terminal to be detected. The biological feature information at least includes one of face feature information, iris feature information and fingerprint feature information;

[0068] When it is determined that the vehicle owner verification request is passed according to the biological feature information of the vehicle owner user, it is determined that the security verification of the vehicle terminal to be detected is passed.

[0069] In the present application, after receiving the access request sent by the vehicle terminal to be detected, in order to ensure that the vehicle terminal is not cracked by a malicious user and thus the vehicle terminal to be detected is used without authorization, thereby affecting the user experience of the vehicle owner, the present application can first perform a vehicle owner verification request on the user using the vehicle terminal to be detected.

[0070] It can be understood that the vehicle owner verification request is used to determine whether the identity of the user using the vehicle terminal to be detected is a legal vehicle owner. In one way, the verification can be performed by collecting the user's biological feature information. Among them, it can be a request for one of the face feature information, iris feature information, and fingerprint feature information of the vehicle owner user. So that the operation platform determines whether the user using the vehicle terminal to be detected is a legal user according to the pre-stored legal vehicle owner user database in the database after receiving the information.

[0071] In one way, the platform sends the request to the vehicle terminal after generating the verification request. When the user using the vehicle terminal agrees to the request, the vehicle terminal to be detected can use the camera, fingerprint sensor, and other collection devices to collect the biological feature information (i.e., at least one of the face feature information, iris feature information, and fingerprint feature information) of the user, and after collecting the corresponding information, the biological feature information is sent to the pre-set biological information database. So that the database determines whether the calling user is a safe user according to the biological feature information, and if so, determines that the user using the vehicle terminal to be detected is a legal user.

[0072] Optionally, in another embodiment based on the above-mentioned method of the present application, the vehicle data is transmitted to the fault detection model to obtain the identification result of the vehicle terminal to be detected, comprising:

[0073] The vehicle data is divided into at least one sub-vehicle data using the fault detection model, wherein each sub-vehicle data corresponds to one data source type;

[0074] Each sub-vehicle data is input into the corresponding decomposition detection model to obtain the corresponding sub-identification result of each sub-vehicle data, wherein each decomposition detection model is used to identify vehicle data of one data source type;

[0075] At least one sub-identification result is summarized to obtain the identification result of the vehicle terminal to be detected.

[0076] Optionally, in another embodiment based on the above-mentioned method of the present application, before receiving the access request sent by the vehicle terminal to be detected, it further comprises:

[0077] Obtain a sample test data set, which includes vehicle data of multiple data source types and corresponding fault identification results;

[0078] The initial random forest model is trained using the sample test data set until the fault detection model that meets the pre-set training condition is obtained.

[0079] In one way, the application can find more than 300 groups of sample test data sets containing vehicle data of multiple data source types and corresponding fault identification results from historical sample test data sets.

[0080] In addition, the application can randomly select 80% as training samples and the remaining 20% as validation samples, use vehicle data of multiple data source types and corresponding fault identification results as characteristic factors, values as yes or no, use initial random forest model to model, and use detection pass or fail as prediction value.

[0081] Further, the initial random forest model accuracy can be verified using the validation sample. The training sample and the validation sample are randomly replaced several times, and the model with the highest accuracy is selected as the final fault detection model.

[0082] Optionally, in another embodiment based on the above method of the application, after the vehicle data is transmitted to the fault detection model to obtain the identification result of the to-be-detected vehicle terminal, the method further comprises:

[0083] If it is determined based on the identification result that the to-be-detected vehicle has a fault event, a fault report is generated and uploaded to a business server.

[0084] By applying the technical solution of the application, after obtaining the access request uploaded by the vehicle terminal, the fault detection model matched with the protocol of the vehicle terminal can be automatically selected to identify whether the vehicle has a fault event based on the subsequent uploaded vehicle data after the security verification is passed, thereby realizing the automatic processing of the automobile safety fault monitoring. Thus, the problem of high operating cost caused by deploying safety monitoring servers for multiple different safety standards in the related art is solved.

[0089] In the present application, an access request sent by a to-be-detected vehicle terminal can be received, and the access request carries an access transmission protocol corresponding to the to-be-detected vehicle terminal; if it is determined that the security verification of the to-be-detected vehicle terminal is passed, a fault detection model matched with the access transmission protocol is selected; vehicle data uploaded by the to-be-detected vehicle terminal is received through the access transmission protocol, and the vehicle data is transmitted to the fault detection model to obtain an identification result of the to-be-detected vehicle terminal.
