Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 shows a flowchart of a first embodiment of the on-vehicle self-diagnosis method of the invention, which includes:
s101, the vehicle-mounted intelligent system sends a diagnosis instruction to the TBOX to control the fault information of the TBOX reading node.
It should be noted that the onboard intelligence system may actively or passively send diagnostic instructions to TBOX. For example, the active mode is: when the main vehicle-mounted intelligent system detects that the battery power is too low, a diagnosis instruction can be actively sent to the TBOX; as another example, the passive mode is: when the user finds that the part is abnormal, the user can send a request instruction for checking the fault to the intelligent system in a voice mode or a key mode, then the intelligent system converts a voice signal into a digital signal or converts a key signal into the digital signal through the voice recognition system, and then a diagnosis instruction is generated according to the digital signal.
In the invention, the information transmission between the vehicle-mounted intelligent system and each node (namely each part of the whole vehicle) is realized through TBOX. After the vehicle-mounted intelligent system generates a diagnosis command, the vehicle-mounted intelligent system sends the diagnosis command to the TBOX through a communication protocol between the vehicle-mounted intelligent system and the TBOX, and therefore the TBOX is controlled to read fault information. The fault information comprises a fault vehicle type, a fault node and a fault code.
For example, TBOX may read and send currently existing fault information to the onboard intelligence system via diagnostic instructions (e.g., 0x19 service).
And S102, receiving the fault information fed back by the TBOX by the vehicle-mounted intelligent system.
S103, the vehicle-mounted intelligent system inquires a diagnosis strategy according to the fault information.
And S104, when the vehicle-mounted intelligent system inquires the diagnosis strategy, the vehicle-mounted intelligent system repairs the fault according to the diagnosis strategy.
And S105, when the diagnosis strategy is not inquired by the vehicle-mounted intelligent system, the vehicle-mounted intelligent system sends the fault information to the cloud server to control the cloud server to inquire the diagnosis strategy, and the fault is repaired according to the diagnosis strategy fed back by the cloud server.
It should be noted that the diagnosis strategy is used for recording a fault detection method, a fault confirmation method and a fault repair method; when the vehicle-mounted intelligent system repairs the fault according to the diagnosis strategy, the fault is detected according to the fault detection method, then the fault is confirmed according to the fault confirmation method and the detection result, and finally the fault is attempted to be repaired according to the fault repair method and the confirmation result.
For example, when a certain fault code is generated and cannot be repaired through some diagnostic instructions or reset operations, software needs to be updated, in this case, the vehicle-mounted intelligent system downloads the latest version of software of the node from the cloud server, and then updates the software after permission of a user, so that the problem of some fault codes is solved.
For another example, for a trial repair by a diagnostic policy but not a successful repair, the on-board intelligent system may need to further analyze whether the failure is caused by a hardware failure of a node. For example, when a fault code that the entire vehicle loses communication with a certain node occurs, the situation may be a software fault of some nodes or a hardware fault of the node. For such conditions, after software problems are eliminated, the hardware needs to be checked again.
Therefore, the diagnosis strategy can be quickly retrieved and the fault can be tentatively repaired through the large data information accumulated by the vehicle-mounted intelligent system and the cloud server.
It should be noted that the cloud server is established and maintained by each large host factory, and for different vehicle models and different nodes, corresponding fault codes are established and diagnosis strategies are designed according to the fault codes.
For example, the cloud server database stores fault codes and corresponding diagnosis strategies of all nodes (e.g., the meter ICM, the reverse sensor RPA, the blind spot detection system BSD, etc.) of the vehicle type a26 and the vehicle type A3K. When a vehicle-mounted intelligent system acquires fault information of a whole vehicle through TBOX, the vehicle-mounted intelligent system firstly queries a self-stored diagnosis strategy, if a diagnosis strategy matched with the fault information is queried, the fault is repaired according to the diagnosis strategy, and if a diagnosis strategy matched with the fault information is not queried, the fault information is sent to a cloud server; after receiving the fault information, the cloud server can inquire the unique corresponding diagnosis strategy according to the fault vehicle type, the fault node and the fault code recorded in the fault information, send the diagnosis strategy to the corresponding vehicle-mounted intelligent system, and then repair the fault according to the diagnosis strategy by the vehicle-mounted intelligent system.
In addition, in the diagnosis process, the vehicle-mounted intelligent system may simultaneously acquire a plurality of diagnosis strategies sent by the cloud server, and the vehicle-mounted intelligent system needs to execute the diagnosis strategies after receiving the diagnosis strategies. The diagnosis strategy can be designed by technicians or generated by a vehicle-mounted intelligent system in a self-learning mode, and different diagnosis strategies can be adopted for different fault information.
For example, the a diagnostic strategy is: the method comprises the steps of sending a detection message to a fault node and analyzing whether the fault node feeds back the message or not, if the fault node does not send the feedback message, on one hand, judging whether the fault node is abnormal in communication due to too low voltage or caused by wire harness connection and the like by reading related states of the voltage of the fault node and the like, once the problem is confirmed, automatically trying to repair according to a corresponding repair strategy by the vehicle-mounted intelligent system, if the fault needs to be solved through updating software, downloading the latest software of the fault node to the local and transmitting the latest software to a TBOX (tunnel boring oxide oxygen sensor), then sending a diagnosis instruction to enter a Bootloader of the fault node through the TBOX, and updating the fault node so as to solve the problem.
For another example, if the reverse sensor does not work, the failure may be caused by software, and the failure can be repaired by updating the software.
If the rearview camera is shielded during backing, the fault is caused by the fact that the camera is blocked by certain things (sludge and the like), the vehicle-mounted intelligent system can inform a user of a solution through a host screen, the user can process the solution by himself and feed back a processing result; and prompting the user to a 4S shop to perform professional maintenance on the problem which cannot be solved.
Therefore, when the vehicle-mounted intelligent system receives the diagnosis strategy, it needs to analyze which messages are to be sent to detect and confirm the fault according to the diagnosis strategy, and determine the cause of the fault according to whether the response condition of each component to the diagnosis messages can be determined, or further confirm which messages are to be sent to try to repair according to the response message data.
Further, when the cloud server does not inquire the diagnosis strategy, the cloud server feeds back the fault information to the user; meanwhile, when the fault cannot be repaired, the vehicle-mounted intelligent system feeds back the repair result to the user.
Therefore, the vehicle-mounted intelligent system, the TBOX and the cloud server are combined, the self-diagnosis mode of the automobile parts is realized, the faults can be effectively checked, analyzed and confirmed, a suggested solution is given through artificial intelligent big data, the faults are automatically tried to be repaired, the manpower and fund investment of the whole automobile factory after sale is reduced, and the failure rate of the whole automobile is reduced.
Referring to fig. 2, fig. 2 shows a flowchart of a second embodiment of the on-vehicle self-diagnosis method of the invention, including:
s201, the vehicle-mounted intelligent system sends a diagnosis instruction to the TBOX to control the fault information of the TBOX reading node.
S202, the vehicle-mounted intelligent system receives fault information fed back by the TBOX.
S203, the vehicle-mounted intelligent system queries a diagnosis strategy according to the fault information.
S204, when the vehicle-mounted intelligent system inquires a diagnosis strategy, the vehicle-mounted intelligent system repairs the fault according to the diagnosis strategy.
S205, when the diagnosis strategy is not inquired by the vehicle-mounted intelligent system, the vehicle-mounted intelligent system sends the fault information to a cloud server to control the cloud server to inquire the diagnosis strategy, and the fault is repaired according to the diagnosis strategy fed back by the cloud server.
S206, the vehicle-mounted intelligent system and the cloud server respectively record relevant information in the fault repairing process
It should be noted that, for a fault that has been repaired once, the vehicle-mounted intelligent system and the cloud server may respectively record relevant information in the fault repair process, thereby implementing the filing of the fault.
And S207, receiving the real-time state information of the nodes by the vehicle-mounted intelligent system.
The real-time status information includes, but is not limited to, current information, voltage information, temperature information, and the like.
And S208, when the real-time state information is matched with any relevant information in the fault repairing process recorded by the vehicle-mounted intelligent system or the cloud server, the vehicle-mounted intelligent system analyzes whether the node has a fault according to the real-time state information and the relevant information.
S209, when the vehicle-mounted intelligent system analyzes that the node has a fault, returning to the step S201.
When the vehicle-mounted intelligent system finds that the real-time state information of some nodes is the same as the real-time state information when the node fails last time, the node may fail the same as the node last time. Therefore, the vehicle-mounted intelligent system needs to perform predictive analysis on the fault according to the abnormal real-time state information, so as to perform pre-judgment on the fault possibly occurring in the node.
Therefore, the invention can obtain the relevant parameters of each part in real time through the diagnosis technology, and realize the prejudgment and the processing of the fault.
Further, the vehicle-mounted self-diagnosis method of the invention further comprises: the vehicle-mounted intelligent system receives real-time parameter information of a vehicle; and when the real-time parameter information reaches a preset value, the vehicle-mounted intelligent system predicts the nodes which reach the service life according to the real-time parameter information and sends prompt information to a user. The real-time parameter information includes node use duration information or vehicle mileage information, but is not limited thereto.
For example, when the vehicle-mounted intelligent system finds that the vehicle mileage information reaches a preset value, the vehicle-mounted intelligent system can prompt a user to perform operations such as tire replacement or engine oil replacement. Therefore, the prediction of the life can be effectively realized by the invention.
The invention is further illustrated by the following specific examples:
the vehicle-mounted intelligent system control TBOX reads that the fault code of the meter ICM (the physical address ID of the meter ICM is 0x72B) in the a26 vehicle model is "0 xC12987 (the fault code is a communication fault code lost with the BCS node)" by the diagnostic instruction "0 x 190209". At the moment, the vehicle-mounted intelligent system acquires fault information 'A26 (fault vehicle type), 72B (fault node) and C12987 (fault code)' through TBOX, when the vehicle-mounted intelligent system does not inquire a diagnosis strategy locally, the fault information is sent to the cloud server through a 4G/5G communication technology, after the cloud server receives the fault information, the fault information is retrieved according to the fault vehicle type, the fault node and the fault code, and a corresponding diagnosis strategy '0 x72B.001:0x 280003' is returned; 0x7ab.100.001: 680003 [101.500 ═ 0x264.0[ … ] ].101[ … ] ", and finally, the vehicle-mounted intelligent system processes the fault according to the diagnosis strategy.
Diagnostic strategy "0 x72B.001:0x 280003; 0x7ab.100.001: 680003 [101.500 ═ 0x264.0[ … ] ].101[ … ] "is command data for controlling the vehicle-mounted intelligent system to execute relevant actions according to instructions, wherein" 0x72B "is an address; "001" is a send instruction code; "002" receives an instruction code; ".' is a command separator; "100" is a control condition, similar to if; "101" is the control condition turn, similar to else; "500" is a special instruction, referring to an address; "[ ]" is a control condition execution section.
The diagnosis strategy is analyzed by the vehicle-mounted intelligent system as follows: 0x 280003 is sent at 0x728 (the physical address of the meter ICM) and if 0x 680003 is sent at 0x7AB (the response address of the meter) (i.e. a positive response to a 0x28 service request), the instruction in "[ ]" is executed, i.e. if the ID 0x264 message is not on-line (where the data code 0x264.0 indicates that the message is not present and 0x264.1 indicates that the message is present), the instruction in the subsequent "[ ]" is executed until the cause of the fault is determined.
Therefore, the vehicle-mounted intelligent system and the cloud server can realize the functions of analyzing fault codes, detecting faults, predicting faults, confirming faults and repairing the faults through the diagnosis strategy. Accordingly, the function implementation is based on a huge database, and the database establishment is accumulated in practice at all, which is the foundation of the artificial vehicle-mounted intelligent system, namely based on big data, and related behaviors are realized through deep learning of a neural network.
