Description

Technical Field

[0001] This disclosure relates to the field of vehicle technology, and in particular to a method, apparatus, device, and storage medium for handling latent failures. Background Technology

[0002] With economic development, cars have become increasingly common in households. To ensure vehicle safety, a safety self-check is performed during each driving cycle. If a latent failure is detected, the affected vehicle part is often immediately disabled to ensure driving safety. However, a latent failure does not directly cause equipment malfunction or harmful behavior. Only after other related failures occur will equipment malfunction. Disabling the vehicle part, on the other hand, renders the vehicle unable to operate normally, severely impacting the user's travel. Therefore, how to handle latent failures to minimize their impact on user travel while ensuring driving safety is a technical problem that needs to be solved. Summary of the Invention

[0003] To address the aforementioned technical problems, this disclosure provides a method, apparatus, device, and storage medium for handling latent failures.

[0004] A first aspect of this disclosure provides a method for handling latent failures, the method comprising:

[0005] Receive at least one latent failure message sent by at least one vehicle within a certain period of time. The latent failure message includes a vehicle identifier and a failure type. The failure type is used to characterize the information of the component that failed the self-test. The vehicle identifier is used to characterize the vehicle's identity information.

[0006] For each vehicle identifier, count the first number of latent failure messages of each failure type sent for each vehicle identifier;

[0007] The first quantity is compared with the first preset quantity. The failure type corresponding to the first quantity being greater than or equal to the first preset quantity is determined as the first failure type. The vehicle corresponding to the vehicle identifier in which the number of latent failure information of the first failure type is greater than or equal to the first preset quantity is determined as the target vehicle.

[0008] Based on the first failure type, a prompt message is generated, which is used to indicate whether the part corresponding to the first failure type in the target vehicle needs to be replaced.

[0009] A second aspect of this disclosure provides an apparatus for handling latent failures, the apparatus comprising:

[0010] The first receiving module is used to receive at least one latent failure information sent by at least one vehicle within a certain period of time. The latent failure information includes a vehicle identifier and a failure type. The failure type is used to characterize the information of a component that has failed a self-test. The vehicle identifier is used to characterize the vehicle's identity information.

[0011] The first statistics module is used to count the first number of latent failure messages of each failure type sent by each vehicle identifier for the vehicle identifier.

[0012] The first determining module is used to compare the first quantity with the first preset quantity, determine the failure type corresponding to the first quantity being greater than or equal to the first preset quantity as the first failure type, and determine the vehicle corresponding to the vehicle identifier in which the number of latent failure information of the first failure type sent is greater than or equal to the first preset quantity as the target vehicle.

[0013] The first generation module is used to generate a prompt message based on the first failure type. The prompt message is used to indicate whether the part corresponding to the first failure type in the target vehicle needs to be replaced.

[0014] A third aspect of this disclosure provides a computer device including a memory and a processor, and a computer program, wherein the memory stores the computer program, and when the computer program is executed by the processor, it implements the latent failure handling method of the first aspect described above.

[0015] A fourth aspect of this disclosure provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the latent failure handling method described in the first aspect above.

[0016] The technical solution provided in this disclosure has the following advantages compared with the prior art:

[0017] In the latent failure processing method, apparatus, device, and storage medium provided in this disclosure embodiment, at least one latent failure message sent by at least one vehicle within a certain period of time is received. The latent failure message includes a vehicle identifier and a failure type. The failure type is used to characterize information about a component that has failed a self-test, and the vehicle identifier is used to characterize the vehicle's identity information. For each vehicle identifier, a first number of latent failure messages of each failure type sent by each vehicle identifier is counted. This first number is compared with a first preset number. Failure types corresponding to a first number greater than or equal to the first preset number are determined as the first failure type. Vehicles corresponding to vehicle identifiers whose number of latent failure messages of the first failure type sent is greater than or equal to the first preset number are determined as target vehicles. The first failure type generates a prompt message, which is used to indicate whether the part corresponding to the first failure type in the target vehicle needs to be replaced. It can uniformly receive latent failure information sent by each vehicle after safety self-check, and determine that the target vehicle has sent latent failure information multiple times for the first failure type based on the vehicle identification and failure type. Thus, it is determined that the part corresponding to the first failure type on the target vehicle has a latent failure. Therefore, a first reminder message is generated to remind relevant personnel whether the part on the target vehicle needs to be replaced. Since the latent failure itself does not directly affect driving safety, as long as the part with the latent failure is replaced in time, there will be no abnormal equipment function or harmful behavior. Therefore, users can use the vehicle normally after the latent failure occurs, meeting the user's travel needs. Attached Figure Description

[0032] Figure 1 This is a flowchart of a method for handling latent failures provided in an embodiment of this disclosure. This method can be executed by a latent failure handling device. Figure 1 As shown, the latent failure handling method provided in this embodiment includes the following steps:

[0033] S101. Receive at least one latent failure message sent by at least one vehicle within a certain period of time. The latent failure message includes a vehicle identifier and a failure type. The failure type is used to characterize the information of a component that has failed a self-test. The vehicle identifier is used to characterize the vehicle's identity information.

[0034] The latent failure information in this embodiment can be understood as information generated when a vehicle detects a latent failure during a safety self-check. The latent failure information includes a vehicle identifier that identifies the vehicle and uniquely identifies the target vehicle, as well as the failure type of the component that failed the self-check. The specific circumstances of the latent failure can be determined through the failure type. For example, the vehicle identifier can be the Vehicle Identification Number (VIN), and the failure type can be the specific component type that experienced the latent failure, such as sensor latent failure, controller latent failure, actuator latent failure, etc., which are not limited here.

[0035] In this embodiment of the disclosure, the latent failure processing device can receive at least one latent failure message, including vehicle identification and failure type, sent by at least one vehicle within a certain period of time.

[0036] In one exemplary embodiment of this disclosure, the latent failure processing device can receive latent failure information sent by at least one vehicle through a data connection, such as a network connection, and summarize and organize the latent failure information received over a period of time in chronological order.

[0037] S102. For the vehicle identifier, count the first number of latent failure information messages of each failure type sent for each vehicle identifier.

[0038] In this embodiment of the disclosure, the latent failure processing device can, after receiving at least one latent failure message sent by at least one vehicle within a certain period of time, count the first number of latent failure messages of each failure type sent by the vehicle corresponding to each vehicle identifier according to the vehicle identifier contained in the latent failure message.

[0039] In one exemplary embodiment of this disclosure, the latent failure processing device can summarize and organize the received latent failure information, classify the latent failure information sent by the vehicle corresponding to each vehicle identifier according to the vehicle identifier contained in the latent failure information, further classify the latent failure information according to the failure type contained in the latent failure information, and count the first quantity of each failure type.

[0040] S103. Compare the first quantity with the first preset quantity, determine the failure type corresponding to the first quantity being greater than or equal to the first preset quantity as the first failure type, and determine the vehicle corresponding to the vehicle identifier in which the number of latent failure information of the first failure type sent is greater than or equal to the first preset quantity as the target vehicle.

[0041] The first failure type in this embodiment can be any type of latent failure. The first preset quantity can be a pre-set threshold for determining whether a latent failure is detected in multiple self-tests in the same vehicle. Its specific value can be set as needed or determined based on the duration of a period of time. For example, when the period of time is three days, the first preset quantity can be three times. This is not limited here.

[0042] The target vehicle in this embodiment can be understood as a vehicle that performs multiple safety self-checks over a period of time, obtains multiple detection results of latent failures including the first failure type, and sends latent failure information for the first failure type to the latent failure processing device multiple times. The number of latent failure information sent by the target vehicle for the first failure type is greater than or equal to the first preset number.

[0043] In this embodiment of the disclosure, the latent failure processing device can, after determining the first number of latent failure information of each failure type sent by each vehicle identifier, compare each first number with a first preset number, and determine the failure type corresponding to the first number being greater than or equal to the first preset number as the first failure type, and determine the vehicle corresponding to the vehicle identifier in which the number of latent failure information of the first failure type sent is greater than or equal to the first preset number as the target vehicle.

[0044] S104. Generate a prompt message based on the first failure type. The prompt message is used to indicate whether the part corresponding to the first failure type in the target vehicle needs to be replaced.

[0045] In this embodiment of the disclosure, the latent failure processing device can, after determining the first failure type and the target vehicle, generate a prompt message based on the first failure type indicating whether the vehicle parts corresponding to the first failure type in the target vehicle need to be replaced.

[0046] In one exemplary embodiment of the present disclosure, the latent failure processing device can, after determining the first failure type and the target vehicle, generate a prompt message based on the identification information of the target vehicle and the first failure type, and output the prompt message in text and voice form through in-vehicle output devices, such as a display screen and a speaker, or display the prompt message on the after-sales platform.

[0047] This embodiment of the disclosure receives at least one latent failure message sent by at least one vehicle within a certain period of time. The latent failure message includes a vehicle identifier and a failure type. The failure type characterizes information about a component that has failed a self-test, and the vehicle identifier characterizes the vehicle's identity information. For each vehicle identifier, a first number of latent failure messages of each failure type are counted. This first number is compared with a first preset number. Failure types corresponding to a first number greater than or equal to the first preset number are determined as the first failure type. Vehicles corresponding to vehicle identifiers that have sent latent failure messages of the first failure type in a number greater than or equal to the first preset number are determined as target vehicles. A notification message is generated based on the first failure type. The notification message is used to indicate whether the part corresponding to the first failure type in the target vehicle needs to be replaced. It can uniformly receive latent failure information sent by each vehicle after safety self-check, and determine that the target vehicle has sent latent failure information multiple times for the first failure type based on the vehicle identification and failure type. This indicates that the part corresponding to the first failure type on the target vehicle has a latent failure, and therefore generates a first reminder message to remind relevant personnel whether the part on the target vehicle needs to be replaced. Since latent failure itself does not directly affect driving safety, as long as the part with latent failure is replaced in time, there will be no abnormal equipment function or harmful behavior. Therefore, users can use the vehicle normally after the latent failure occurs, meeting the user's travel needs.

[0048] Figure 2 This is a flowchart of a method for generating notification information provided in an embodiment of this disclosure, such as... Figure 2 As shown, based on the above embodiments, notification information can be generated using the following method.

[0049] S201. In the at least one latent failure information, for each failure type, count the second number of vehicle identifiers corresponding to the failure type.

[0050] In this embodiment of the disclosure, the latent failure processing device can, after receiving at least one latent failure message within a certain period of time, count the number of vehicle identifiers corresponding to each failure type in the at least one latent failure message, and determine it as a second number.

[0051] In one exemplary embodiment of the present disclosure, the latent failure processing device can summarize and organize the latent failure information received within a period of time, determine all failure types contained in all latent failure information, and for each failure type, count the number of vehicle identifiers corresponding to that failure type and determine it as a second number, until the second number of vehicle identifiers corresponding to all failure types has been counted.

[0052] S202. Compare the second quantity with the second preset quantity, and determine the failure type where the second quantity is greater than or equal to the second preset quantity as the second failure type.

[0053] The second failure type in this embodiment can be understood as any type of latent failure. The second failure type can be the same as or different from the first failure type, and no limitation is made here.

[0054] The second preset quantity in this embodiment can be understood as a pre-set threshold for determining whether a latent failure is prevalent in a large number of vehicles, and its specific value can be set as needed.

[0055] In this embodiment of the disclosure, the latent failure processing device can, after statistically obtaining the second number of vehicle identifiers corresponding to each failure type, compare the second number with a second preset number, determine whether the second number is greater than or equal to the second preset number, and determine the failure type whose second number is greater than or equal to the second preset number as the second failure type.

[0056] S203. Generate notification information based on the second failure type, the notification information being used to notify the analysis of the second failure type.

[0057] In this embodiment of the disclosure, the latent failure processing device can determine that the second number of vehicle identifiers corresponding to a certain failure type is greater than or equal to a second preset number. After determining that the failure type is the second failure type, it can determine that the latent failure of the second failure type has been widely occurring in a large number of vehicles. At this time, it is necessary to generate notification information to notify the analysis of the second failure type.

[0058] This embodiment of the disclosure, in the at least one latent failure information, for each failure type, counts a second number of vehicle identifiers corresponding to the failure type, compares the second number with a second preset number, determines the failure type whose second number is greater than or equal to the second preset number as the second failure type, generates notification information based on the second failure type, the notification information is used to notify the analysis of the second failure type, can determine that a systemic failure may have occurred when a certain latent failure type commonly occurs in a large number of vehicles, and needs to notify the analysis of the failure type, eliminate the failure, and avoid causing more serious problems.

[0059] Figure 3 This is a flowchart of another method for generating notification information provided in this disclosure embodiment, such as... Figure 3 As shown, based on the above embodiments, notification information can be generated by the following method, wherein the notification information includes first notification information and second notification information.

[0060] S301. Among the at least one latent failure information, count the third number of latent failure information containing the second failure type.

[0061] In this embodiment of the disclosure, the latent failure processing device can summarize and organize the received latent failure information containing the second failure type, count the number of latent failure information containing the second failure type, and determine it as the third quantity.

[0062] S302. If the third quantity is greater than or equal to the third preset quantity, then generate a first notification message based on the second failure type.

[0063] The third preset quantity in this embodiment can be understood as a pre-set threshold for determining whether a latent failure occurs multiple times in multiple vehicles, and its specific value can be set as needed.

[0064] In this embodiment of the disclosure, the latent failure processing device can, after obtaining a third quantity, compare it with a third preset quantity. If the third quantity is greater than or equal to the third preset quantity, a first notification message is generated based on the second failure type, thereby notifying the analysis of the second failure type.

[0065] S303. If the third quantity is less than the third preset quantity, then a second notification message is generated based on the second failure type, and the processing priority of the first notification message is higher than the processing priority of the second notification message.

[0066] In this embodiment of the disclosure, the latent failure processing device can compare the third quantity with a third preset quantity after obtaining the third quantity. If the third quantity is less than the third preset quantity, a second notification message is generated based on the second failure type, thereby notifying the analysis of the second failure type. The processing priority of the first notification message is higher than that of the second notification message. Specifically, when there is a first notification message for the second failure type A and a second notification message for the second failure type B at the same time, the second failure type A will be analyzed and processed first, and the second failure type B will be analyzed and processed after the analysis and processing of the second failure type A is completed.

[0067] This embodiment of the disclosure counts a third number of latent failure information containing the second failure type from the at least one latent failure information. If the third number is greater than or equal to a third preset number, a first notification is generated based on the second failure type. If the third number is less than the third preset number, a second notification is generated based on the second failure type. The processing priority of the first notification is higher than that of the second notification. This allows for the determination of the priority of processing and analyzing latent failures of a certain type based on the frequency of occurrence of that type of latent failure after determining that a certain type of latent failure commonly occurs in multiple vehicles. Priority is given to processing failure types with a larger number of reported failures, thereby further reducing the impact of latent failures on vehicle owners.

[0068] Figure 4 This is a flowchart of a method for evaluating vehicle parts provided in an embodiment of this disclosure, such as... Figure 4 As shown, based on the above embodiments, vehicle parts can be evaluated using the following methods.

[0069] S401. In the at least one latent failure information, for each failure type, count the fourth number of latent failure information corresponding to the failure type.

[0070] In this embodiment of the disclosure, the latent failure processing device can, after receiving at least one latent failure message, count the number of latent messages corresponding to each failure type contained in each latent failure message and determine it as the fourth quantity.

[0071] S402. The ratio of the fourth quantity to the preset total number of vehicles is determined as the failure probability of the failure type.

[0072] The total number of vehicles in this embodiment can be understood as the total number of vehicles that have a communication connection with the latent failure processing device and that send latent failure information to the latent failure processing device when a latent failure occurs. This number can be preset by the staff according to the actual situation, or it can be obtained by periodically conducting communication tests and statistics, and is not limited here.

[0073] In this embodiment of the disclosure, the latent failure processing device can, after obtaining the fourth quantity, calculate the ratio of the fourth quantity corresponding to each failure type to the preset total number of vehicles for each failure type, and determine the ratio as the failure probability corresponding to each failure type. For example, if 30 out of 100 latent failure messages received within a certain period of time contain failure type A, then the fourth quantity corresponding to failure type A is 30. If the preset total number of vehicles is 1000, then the failure probability corresponding to failure type A is 30 / 1000 = 3%.

[0074] S403. Use the failure probability to perform a quality assessment on the vehicle parts corresponding to the failure type.

[0075] In this embodiment of the disclosure, the latent failure processing device can calculate the failure probability of each failure type, determine the failure probability of the vehicle part corresponding to each failure type based on the correspondence between each failure type and the vehicle part, and then use the failure probability to perform quality assessment on the vehicle part. For example, for the same vehicle part, the lower the failure probability, the better the quality assessment result.

[0076] In an exemplary embodiment of this disclosure, the latent failure processing device can, after determining the failure probability of vehicle parts corresponding to each failure type, calculate the product of the evaluation coefficient and the failure probability according to the evaluation coefficient corresponding to each vehicle part, and determine the product as the quality evaluation score result. For example, failure type A corresponds to vehicle part 1, and the evaluation coefficient corresponding to vehicle part 1 is 10. If the failure probability corresponding to failure type A is 3%, then the quality evaluation of vehicle part 1 corresponding to failure type A is 0.3.

[0077] In another exemplary embodiment of this disclosure, if a vehicle part corresponds to multiple failure types, the latent failure processing device can accumulate the failure probabilities of the multiple failure types corresponding to the vehicle part and use the accumulated result to evaluate the quality of the vehicle part. Alternatively, it can perform a weighted average calculation on the failure probabilities of the multiple failure types corresponding to the vehicle part and use the weighted average calculation result to evaluate the quality of the vehicle part. For example, failure type A and failure type B both correspond to vehicle part 1, and the weights of failure type A and failure type B are 0.6 and 0.4, respectively. If the failure probability corresponding to failure type A is 3% and the failure probability corresponding to failure type B is 8%, then the quality evaluation result corresponding to vehicle part 1 is 3%*0.6+8%*0.4=5%.

[0078] This embodiment of the disclosure, in the at least one latent failure information, for each failure type, counts a fourth number of latent failure information corresponding to the failure type, determines the failure probability of the failure type by the ratio of the fourth number to the preset total number of vehicles, and uses the failure probability to perform quality assessment on the vehicle parts corresponding to the failure type. It can perform quality assessment on vehicle parts based on latent failure information, thereby deciding whether to replace or optimize the vehicle parts.

[0079] Figure 5 This is a flowchart of a method for alerting to latent failures provided in an embodiment of this disclosure, such as... Figure 5 As shown, based on the above embodiments, latent failures can be alerted by the following method, wherein the alert information includes a first alert information and a second alert information.

[0080] S501. Send a control command to the target vehicle, the control command being used to control the target vehicle to perform a secondary safety self-check.

[0081] In this embodiment of the disclosure, the latent failure handling device can send a control command to the target vehicle based on a pre-established communication connection after determining the existence of the target vehicle, so that the target vehicle can perform a secondary safety self-check after receiving the control command.

[0082] S502, Receive the detection result returned by the target vehicle.

[0083] In this embodiment of the disclosure, the latent failure handling device can receive the detection results of the secondary safety self-test returned by the target vehicle after the target vehicle completes the secondary safety self-test based on the control command.

[0084] S503. If the detection result includes the first failure type, then generate a first prompt message based on the first failure type. The first prompt message is used to prompt the replacement of the part corresponding to the first failure type in the target vehicle.

[0085] In this embodiment of the present disclosure, the latent failure processing device can analyze the detection results returned by the target vehicle after receiving the detection results, determine whether the detection results contain latent failure information of the first failure type, and if so, generate a first prompt message based on the first failure type to prompt the replacement of the part corresponding to the first failure type in the target vehicle.

[0086] S504. If the detection result does not include the first failure type, then a second prompt message is generated based on the first failure type. The second prompt message is used to prompt the inspection of the accessories corresponding to the first failure type in the target vehicle.

[0087] In this embodiment of the disclosure, the latent failure processing device can, after receiving the detection result returned by the target vehicle, generate a second prompt message based on the first failure type to prompt the inspection of the accessories corresponding to the first failure type in the target vehicle if the detection result does not contain latent failure information of the first failure type.

[0088] This embodiment of the disclosure sends a control command to the target vehicle, which controls the target vehicle to perform a secondary safety self-check and receives the detection results returned by the target vehicle. If the detection results contain the first failure type, a first prompt message is generated based on the first failure type. The first prompt message prompts the replacement of the part corresponding to the first failure type in the target vehicle. If the detection results do not contain the first failure type, a second prompt message is generated based on the first failure type. The second prompt message prompts the inspection of the part corresponding to the first failure type in the target vehicle. This allows the target vehicle to perform a secondary safety self-check after determining that the number of latent failure messages sent by the target vehicle for the first failure type is greater than or equal to a first preset number. This secondary judgment allows the user to understand the subsequent processing procedure based on the first or second prompt message and take appropriate action, further improving driving safety.

[0089] In some embodiments of this disclosure, the latent failure processing device can determine whether the target vehicle is in a non-driving state before sending a control command to the target vehicle. If the target vehicle is in a non-driving state, a control command is sent to enable the target vehicle to complete a secondary safety self-check. If the target vehicle is not in a non-driving state, the time for sending the control command is delayed to avoid affecting the user's driving trip due to the secondary safety self-check, thereby further improving the user experience.

[0090] In some other embodiments of this disclosure, the latent failure information further includes self-test time and self-test log file. The latent failure processing device can record the latent failure information of the first failure type in the database after generating prompt information based on the first failure type.

[0091] Specifically, after receiving at least one latent failure message, the latent failure processing device can not only obtain the vehicle identification and identity information contained in the latent failure message, but also obtain the self-test time when the latent failure was detected, as well as the self-test log file recorded when the latent failure was detected. The self-test log file can record the vehicle's real-time status information, such as vehicle speed, acceleration, remaining battery power, and remaining fuel. After generating a prompt message, the latent failure processing device can record the latent failure information, including the self-test time and the self-test log file, in the database so that subsequent correlation analysis of the first failure type can be performed based on the data accumulated in the database to determine the cause of the first failure type.

[0092] Figure 6 This is a schematic diagram of the structure of a latent failure handling device provided in an embodiment of this disclosure, as shown below. Figure 6 As shown, the latent failure processing device 600 includes: a first receiving module 610, a first statistics module 620, a first determination module 630, and a first generation module 640. The first receiving module 610 is used to receive at least one latent failure message sent by at least one vehicle within a certain period. The latent failure message includes a vehicle identifier and a failure type. The failure type is used to characterize information about a component that has failed a self-test, and the vehicle identifier is used to characterize the vehicle's identity information. The first statistics module 620 is used to count, for each vehicle identifier, the number of latent failure messages of each failure type sent by each vehicle identifier. The first determination module 630 is used to compare the first number with a first preset number, determine the failure type corresponding to a first number greater than or equal to the first preset number as the first failure type, and determine the vehicle corresponding to the vehicle identifier whose number of latent failure messages of the first failure type sent is greater than or equal to the first preset number as the target vehicle. The first generation module 640 is used to generate a prompt message based on the first failure type, the prompt message indicating whether the component corresponding to the first failure type in the target vehicle needs to be replaced.

[0093] Optionally, the latent failure processing device 600 further includes: a second statistics module, used to count a second number of vehicle identifiers corresponding to each failure type in the at least one latent failure information; a second determination module, used to compare the second number with a second preset number, and determine the failure type whose second number is greater than or equal to the second preset number as the second failure type; and a second generation module, used to generate notification information based on the second failure type, the notification information being used to notify the analysis of the second failure type.
