Example one
For the convenience of understanding the technical solutions of the present application, the vehicle detection system provided in the present application will be described below with reference to the accompanying drawings.
Referring to fig. 2, which is a block diagram of a vehicle fault detection system provided in an embodiment of the present application, as shown in fig. 2, the system may include: the vehicle-mounted communication device 101, the terminal 20, and the server 30.
In this embodiment, the vehicle-mounted communication device 101 is configured to receive the operation parameter sent by the vehicle-mounted controller 102, and send the operation parameter to the terminal. The vehicle-mounted controller 102 is configured to monitor an operating parameter of the vehicle 10 during operation, and send the operating parameter to the vehicle-mounted communication device 101.
In this embodiment, the vehicle-mounted controller ECU102 may monitor the running state of the vehicle in real time, acquire operating parameters of the vehicle during running, where the operating parameters may include the running speed of the vehicle, the rotation speed of the engine, the working duration of the brake pad, and the like, and send the acquired vehicle operating parameters to the vehicle-mounted communication device 101.
And the terminal 20 is used for analyzing whether the vehicle has a fault according to the operation parameters and sending the operation parameters to the server 30 when the vehicle has the fault.
In this embodiment, the terminal 20 may analyze the current operation state of the vehicle according to the received operation parameters, and determine whether the vehicle has a fault. In a specific implementation, the terminal 20 may be installed with a client for analyzing the operation parameters, where the client stores the operation parameters of the vehicle during normal operation in advance, and when the terminal 20 receives the operation parameters, the client performs analysis and comparison according to the current operation parameters of the vehicle and the pre-stored parameters in advance to determine whether the vehicle has a fault. When it is determined that the vehicle is out of order, the terminal 20 transmits the operation parameters to the server 30.
In addition, in a possible implementation manner, when the terminal 20 receives the operation parameters of the vehicle, the operation parameters may be graphically displayed, so that a user may visually check the operation data of the vehicle, and a user experience is provided.
And the server 30 is used for determining the fault information of the vehicle according to the operation parameters and sending the fault information to the terminal.
In this embodiment, the terminal 20 sends the operating parameters of the vehicle with the fault to the server 30, that is, sends the fault parameters to the server 30, the server 30 determines the fault information of the vehicle according to the fault data, the fault information includes the fault type of the vehicle, and sends the fault information to the terminal 20, and then the terminal 20 prompts the user according to the fault information, so that the user can know that the vehicle has the fault in time, and the occurrence of safety accidents is avoided.
In practical applications, the server 30 may determine the type of the vehicle failure according to the operation parameters, and the failure type may be a failure type previously set in the server 30 by a maintenance person. Such as overheating and leakage. For example, in a normal situation, when an automobile runs, a certain working temperature is maintained, when the acquired temperature of the engine is higher than a preset threshold value, it is determined that the vehicle has an overheating phenomenon, which indicates that a problem occurs in a cooling system or an ignition system, the server 30 sends information for determining that the vehicle has the overheating phenomenon to the terminal 20, so that the terminal 20 timely notifies a user to perform troubleshooting, and risks such as pre-ignition, knocking and the like are avoided.
In a possible implementation manner, the fault information may further include a fault category of the vehicle and operation guidance information for the fault level, so that a user may perform related operations according to the operation guidance information to avoid occurrence of a safety accident.
In this embodiment, the server 30 may determine the level of the vehicle failure according to the operating parameters, where the failure level may be determined according to the consequences caused by the vehicle failure, for example, if only the influence on the vehicle entertainment system is not able to work normally, the failure type is determined to be a low-level failure; when the normal running of the vehicle is influenced, determining that the fault type is a medium-level fault; when an unintended acceleration of the vehicle may be caused, the fault type is determined to be a high-level fault. Of course, the failure level may be set according to other conditions, and the setting of the failure level is not limited in this embodiment.
In practical application, the server 30 may also determine operation guidance information corresponding to the level of the vehicle failure according to the level of the vehicle failure, and send the operation guidance information to the terminal 20, so that the terminal 20 guides a user to perform an operation according to the operation guidance information, so as to eliminate potential safety hazards caused by the vehicle failure in time. For example, the operation guidance information may be "in-time maintenance" when the failure level is a low-level failure; when the fault level is a medium-level fault, the operation guidance information may be "please repair immediately"; when the failure level is a high-level failure, the operation guidance information may be "please stop immediately and repair immediately". Of course, the specific content of the operation guidance information may be set according to the actual situation, and the embodiment is not limited to the specific embodiment of the operation guidance information.
In this embodiment, the vehicle-mounted communication device 101 may communicate with the vehicle-mounted controller 102 and the terminal 20, so as to obtain the operating parameter of the vehicle from the vehicle-mounted controller 102 and send the operating parameter to the terminal 20, and in a specific implementation, as shown in fig. 3, the vehicle-mounted communication device 101 may include a controller area network module 1011 and a wireless communication module 1012.
In this embodiment, the controller area Network module 1011 is configured to obtain the operation parameters of the vehicle 10 from the vehicle-mounted controller 102 through a Controller Area Network (CAN) bus.
In practical application, the controller area network module 1011 is connected to the onboard controller 102 through a CAN bus, and the onboard communication device 101 CAN obtain the operating parameters of the vehicle from the onboard controller 102 through the CAN bus. The embodiment of the present application provides two specific implementation manners, and the two implementation manners will be described below, where the vehicle-mounted communication device 101 obtains the operating parameters of the vehicle through the CAN bus.
A mode for obtaining the operation parameter is that the vehicle-mounted controller 102 adds the obtained vehicle operation parameter to a CAN bus message and sends the CAN bus message to a CAN bus, the vehicle-mounted communication equipment monitors the CAN bus message on the CAN bus in real time through a controller local area network module, and when the CAN bus message is monitored to exist on the CAN bus, the vehicle-mounted communication equipment receives the CAN bus message and extracts the vehicle operation parameter from the CAN bus message.
Another way to acquire the operating parameters is that the vehicle-mounted communication device initiates a Universal Diagnostic Service (UDS) Diagnostic session to the vehicle-mounted controller through the controller local area network module, and when the vehicle-mounted controller establishes the UDS Diagnostic session with the vehicle-mounted communication device, the vehicle-mounted communication device acquires the operating parameters of the vehicle from the vehicle-mounted controller through the UDS Diagnostic session.
During specific implementation, the vehicle-mounted communication equipment can acquire the running parameters of the vehicle in the two modes and sends the running parameters to the terminal.
A wireless communication module 1012 for communicating with the terminal 20.
In this example, when the vehicle-mounted communication device 101 acquires the operation parameters of the vehicle, the operation parameters are sent to the terminal 20 through the wireless communication module 1012. In a specific implementation, the wireless communication module may be a bluetooth wireless communication module.
In practical application, the information of the vehicle fault can be recorded so as to provide data reference for subsequent maintenance, and based on this, in a possible implementation manner of the embodiment of the present application, after the server acquires the fault data of the vehicle, the server may store the fault data, specifically, the server 30 includes a fault information database 301; a fault information database 301 for storing operating parameters; and the server 30 is also used for carrying out data analysis according to the operating parameters in the fault information database so as to provide data reference for the maintenance vehicle.
In this embodiment, when the terminal 20 determines that the vehicle has a fault, the operation parameters of the vehicle may be sent to the server 30, and when the server 30 determines information of the fault type, the fault level, and the like of the vehicle according to the operation parameters, the operation parameters of the vehicle may be stored in the fault information database 301, and the operation parameters of the fault database 301 may be periodically analyzed to obtain a fault condition of the vehicle, and meanwhile, the analysis result may be sent to an equipment manufacturer to provide reference data for subsequent maintenance and product quality improvement, so as to improve the quality of the vehicle, and further improve driving safety. See fig. 4 for a schematic diagram of the server architecture.
It can be understood that, with the continuous development of the technology, the vehicles are also continuously updated, and the parts of the vehicles need to be upgraded, so as to improve the driving safety and the user experience. Especially for upgrading of vehicle-mounted controllers, the method is very necessary.
Based on this, in one possible implementation manner of the embodiment of the present application, the server 30 may further include a firmware database 302, where the firmware database 302 is used to store the latest firmware of the onboard controller; the server 30 may send the latest firmware of the vehicle-mounted controller in the firmware database 302 to the terminal 20, then the terminal 20 sends the latest firmware of the vehicle-mounted controller to the vehicle-mounted communication device 101, and finally the vehicle-mounted communication device 101 refreshes the firmware of the vehicle-mounted controller by using the latest firmware of the vehicle-mounted controller according to the unified diagnostic service protocol UDS.
In specific implementation, the vehicle-mounted controller 102 may send a firmware refresh request to the terminal 20 through the vehicle-mounted communication device 101, where the firmware refresh request may include an ID of the vehicle-mounted controller 102 and a firmware version number owned by the vehicle-mounted controller 102, and then the terminal 20 sends the firmware refresh request to the server 30, and the server 30 searches for a latest firmware corresponding to the vehicle-mounted controller from a firmware database according to the ID and the firmware version number in the firmware refresh request, and then sends the latest firmware to the terminal 20, and then the terminal 20 sends the latest firmware to the vehicle-mounted communication device 101, and the vehicle-mounted communication device 101 performs firmware refresh on the vehicle-mounted controller 102 through a UDS protocol, thereby completing function upgrade or fault repair of the vehicle-mounted controller.
It can be understood that when the vehicle-mounted communication equipment communicates with the terminal and the terminal communicates with the server, communication connection needs to be established in advance, so that normal communication among the vehicle-mounted communication equipment, the terminal and the server is guaranteed.
In a possible implementation manner of the present application, when the vehicle-mounted communication device communicates with the terminal for the first time, the vehicle-mounted communication device 101 sends the ID of the vehicle-mounted communication device and the ID of the vehicle to the terminal 20; the terminal 20 is further configured to bind the ID of the vehicle-mounted communication device, the ID of the vehicle, and information registered by the user at the terminal, and send the bound ID of the vehicle-mounted communication device, the ID of the vehicle, and the registration information to the server 30; and the server 30 is also used for carrying out verification according to the ID of the bound vehicle-mounted communication equipment, the ID of the vehicle and the registration information so as to communicate with the terminal 20 when the verification is passed.
In practical application, when a vehicle leaves a factory, IDs may be allocated to the vehicle and vehicle-mounted communication devices configured on the vehicle in advance, and a user registers in a client corresponding to the terminal 20 to obtain a user name and a password during registration, where the client may be configured to analyze an operation parameter and determine whether the vehicle has a fault, and when the vehicle-mounted communication device 101 needs to communicate with the terminal 20, the vehicle-mounted communication device 101 sends the ID of the vehicle and the ID of itself to the terminal 20, so that the terminal 20 binds the vehicle ID and the vehicle-mounted communication device ID with registration information, and in subsequent communication, can verify whether the vehicle-mounted communication device is a legal device according to the binding information. Then, the terminal 20 sends the bound vehicle ID, the vehicle-mounted communication ID and the registration information to the server 30, the server 30 verifies whether the user corresponding to the client has the communication right according to the received information, and the server 30 communicates with the terminal 20 only when the verification is passed.
