[0059] This application provides a vehicle fault diagnosis method, apparatus, vehicle, and storage medium. The technical solution includes: obtaining a vehicle fault category; generating a current status code based on a preset mapping rule and the vehicle fault category; storing the current status code in a preset storage partition, wherein each preset storage partition is used to store the current status code for one vehicle fault category; responding to a diagnosis request for a target fault, selecting a target storage partition for the target fault from the preset storage partitions; reading the current status code from the target storage partition and using the read current status code as the target status code for the target fault; determining a target diagnosis strategy for the target fault based on the preset mapping rule and the target status code; and performing fault diagnosis on the target fault according to the target diagnosis strategy. On the one hand, by instantly generating the current status code of the vehicle fault category through preset mapping rules and storing it in a preset storage partition, timely capture and partition management of the current status data at the time of fault occurrence is realized. This not only provides a comprehensive and reliable basis for fault diagnosis but also ensures the identifiability, readableness, and ease of reading of the current status code. On the other hand, by determining the target storage partition of the target fault from the preset storage partition and reading the current status code stored in the target storage partition as the basis for analysis of the target fault, it helps to quickly and accurately locate the target fault and the applicable target diagnosis strategy. This enables reliable fault diagnosis of the target fault based on the target diagnosis strategy, effectively ensuring the accuracy of the fault diagnosis results.

[0060] This application provides a vehicle fault diagnosis method, relating to the field of fault handling technology. The vehicle fault diagnosis method provided in this application can be applied to a vehicle or can be software running within a vehicle. The vehicle can be a private car, such as a sedan, SUV, MPV, or pickup truck. The vehicle can also be a commercial vehicle, such as a van, bus, small truck, or large trailer. The vehicle can be a gasoline-powered vehicle or a new energy vehicle. When the vehicle is a new energy vehicle, it can be a hybrid vehicle or a pure electric vehicle; the software can be an application that implements the vehicle fault diagnosis method, but is not limited to the above forms.

[0061] Reference Figure 1 This application provides a vehicle fault diagnosis method, which may include, but is not limited to, steps S101 to S107, as follows:

[0062] Step S101: Obtain the vehicle fault category.

[0063] For example, a vehicle may experience various types of malfunctions, such as air conditioning system malfunctions (e.g., failure of the air conditioning natural ventilation function), navigation system malfunctions, and sensor system malfunctions. In the event of a vehicle malfunction, the vehicle malfunction category is determined.

[0064] Step S102: Generate the current status code according to the preset mapping rules and vehicle fault category.

[0065] The current status code is generated instantly based on preset mapping rules and vehicle fault categories. This enables timely capture and management of real-time status data at the time of fault occurrence, providing effective and reliable analytical basis for fault diagnosis.

[0066] In step S102 of some embodiments, the occurrence time of the vehicle fault category can be obtained to obtain the fault time; the status indication information of the vehicle fault category can be obtained, wherein the status indication information is a prompt signal used to indicate the current status of the vehicle fault category; the fault time and status indication information are encoded according to a preset mapping rule to obtain the current status code.

[0067] Obtain the occurrence time of the vehicle fault category, get the fault time (such as a timestamp), and obtain the status indication information of the vehicle fault category.

[0068] The status indication information refers to the prompt signal used to indicate the current state of the vehicle fault category at the time of its occurrence. It can be understood that the status indication information for a vehicle fault category includes at least one prompt signal indicating an abnormal current state.

[0069] For example, taking a malfunction in the air conditioning natural ventilation function as an example, the status indication information corresponding to the malfunction may include a prompt signal for the natural ventilation input command status, a prompt signal for the power mode status, a prompt signal for the recirculation damper motor status, and a prompt signal for the blower status. Therefore, assuming the vehicle experiences a malfunction in the air conditioning natural ventilation function, at least one of these prompt signals will be an abnormal status signal.

[0070] Then, according to the preset mapping rules, the fault time and status indication information are encoded to obtain the current status code.

[0071] The current status code refers to a numerical code that characterizes the type of vehicle malfunction, its time of failure, and its real-time status. The size of the current status code can be flexibly set according to requirements and is not limited thereto.

[0072] Preset mapping rules refer to pre-defined rules that convert the fault time and status indication information of a vehicle fault category into the current status code of the vehicle fault category. It should be noted that preset mapping rules can also reversely convert the current status code back into the fault time and status indication information of the vehicle fault category.

[0073] For example, a preset mapping rule could be to convert the fault time and status indication information of the vehicle fault category into a 16-bit numerical code. To ensure the recognizability of the current status code, each of the first five digits can be defined to represent one of the real-time states corresponding to the fault (e.g., the fifth digit represents the blower status, the fourth digit represents the circulating damper motor status, the third digit represents the power mode status, the second digit represents the natural ventilation input command status, and the first digit represents the remaining real-time states corresponding to the fault, where 0 indicates normal status and 1 indicates abnormal status). It is understood that to reduce the storage space occupied by the current status code, the occurrence time can be simplified to a fixed value, such as representing the fault time "23:59" in binary as "10111111011", thus defining the sixth to sixteenth digits as representing the fault time.

[0074] Taking a vehicle experiencing a natural ventilation malfunction at 11:59 PM as an example, the status indication information corresponding to this natural ventilation malfunction includes a normal natural ventilation input command status, a normal power mode status, a normal circulation damper motor status, and an abnormal blower status. The current status code corresponding to the natural ventilation malfunction would be something like "0000110111111011".

[0075] In this way, by encoding the fault time and status indication information of vehicle fault categories into current status codes, the complex current status indication information can be converted into concise current status codes. This not only facilitates storage and management, but also provides timely, effective, comprehensive and reliable analytical basis for fault identification and location, thus laying the foundation for effective fault response and troubleshooting.

[0076] Step S103: Store the current status code into a preset storage partition, wherein each preset storage partition is used to store the current status code of a vehicle fault category.

[0077] After generating the current status code for the vehicle fault category, the current status code for the vehicle fault category is stored in the preset storage partition corresponding to the vehicle fault category, thereby realizing partition management of the current status code for the vehicle fault category and ensuring the readability and ease of reading of the current status code.

[0078] In step S103 of some embodiments, a preset storage partition of the vehicle fault category can be matched; the current status code is assigned to the preset storage partition for storage.

[0079] Specifically, a specific storage area of ​​a certain size can be pre-allocated in the vehicle's local memory to store the current status code. To achieve reasonable utilization of the specific storage area and improve its utilization rate, the specific storage area can be divided into multiple storage partitions (defined as preset storage partitions).

[0080] To distinguish which vehicle fault category's current status code each preset storage partition is used to store, each preset storage partition can be identified. For example, the letter "E" can be used to identify the preset storage partition used to store the current status code for air conditioning natural ventilation function faults, and the letter "G" can be used to identify the preset storage partition used to store the current status code for navigation system faults.

[0081] In this way, the preset storage partition of the vehicle fault category can be matched, and the current status code of the vehicle fault category can be assigned to the matching preset storage partition for storage.

[0082] For example, to avoid excessive use of the vehicle's local memory, a 1KB storage space can be pre-allocated in the vehicle's local memory. This 1KB storage space contains 1024 bytes. Multiple bytes can be used as a pre-allocated storage partition to store the current status code of a vehicle fault category. For example, two bytes can be used as a pre-allocated storage partition. The first to fifth bits of the 16 bits in the two bytes represent one of the real-time states of the vehicle fault category, and the last 11 bits represent the time when the vehicle fault category occurred.

[0083] If the letter "E" is used to identify the first and second bytes, and these two bytes are divided into the preset storage partition to which the air conditioner natural ventilation function failure belongs, the current status code "0000110111111011" of the air conditioner natural ventilation function failure can be allocated to these two bytes for storage. The first to fourth bits of these two bytes represent other normal states, the fifth bit represents the abnormal state of the blower, and the last 11 bits represent the failure time "23:59".

[0084] This enables timely capture and reasonable management of real-time status data at the time of fault occurrence.

[0085] Understandably, each preset storage partition has good scalability, allowing for increased space, and there is no limit to the size of the preset storage partition.

[0086] Reference Figure 2 In some embodiments, in order to save space in the preset storage partition, steps S201 to S205 may be included after step S103.

[0087] Step S201: Obtain the available capacity of the preset storage partition.

[0088] Specifically, for a preset storage partition, its available capacity is obtained.

[0089] Step S202: Detect the usability status of the preset storage partition based on the available capacity.

[0090] Then, based on the available capacity, the usability status of the preset storage partition is detected.

[0091] For example, a capacity threshold (defined as a preset threshold) can be preset to determine whether the available capacity of the preset storage partition has reached the preset threshold. If the available capacity has reached the preset threshold, the usable state is determined to be that the preset storage partition is unusable.

[0092] Step S203: If the status indicates that the preset storage partition is unusable, obtain the current status code of the preset storage partition and the order of its storage.

[0093] If the preset storage partition is unusable when the available status indicates that the preset storage partition is not available, obtain the current status code of the preset storage partition and the order of its storage.

[0094] Step S204: Based on the order of storage, filter out candidate status codes from the current status codes of the preset storage partition, where the candidate status codes are the status codes that need to be deleted.

[0095] Based on the storage order, candidate status codes that need to be deleted are selected from the current status codes of the preset storage partition.

[0096] Step S205: Delete candidate status codes.

[0097] Finally, the candidate status codes are deleted.

[0098] For example, according to the order of storage from first to last, several current status codes stored in the preset storage partition are filtered out as candidate status codes for deletion.

[0099] This allows for rolling updates of the current status code, saving space in the preset storage partition while ensuring that the preset storage partition always retains the latest real-time status code, thus providing the latest analytical basis for troubleshooting that can be quickly identified.

[0100] Step S104: In response to the troubleshooting request for the target fault, the target storage partition for the target fault is selected from the preset storage partitions.

[0101] Troubleshooting personnel and other users can trigger a troubleshooting request to investigate the target fault. In response to this troubleshooting request, the target storage partition of the target fault is quickly located from the preset storage partitions.

[0102] Step S105: Read the current status code from the target storage partition and use the read current status code as the target status code for the target fault.

[0103] Read the current status code stored in the target storage partition and use the read current status code as the target status code for the target fault.

[0104] Step S106: Determine the target troubleshooting strategy for the target fault based on the preset mapping rules and target status codes.

[0105] Then, the target troubleshooting strategy is determined based on the preset mapping rules and target status codes.

[0106] Reference Figure 3 In order to locate the target troubleshooting strategy more quickly and accurately, and to effectively ensure the accuracy of the troubleshooting results, step S106 in some embodiments may include sub-steps S1061 to S1063.

[0107] Step S1061: According to the preset mapping rules, decode the target status code to obtain the target fault time and target status indication information of the target fault.

[0108] Specifically, according to the preset mapping rules, the target status code is decoded to convert the target status code into the target fault time and target status indication information corresponding to the target fault.

[0109] Step S1062: Obtain the set of troubleshooting strategies for the target fault.

[0110] In order to improve the convenience and efficiency of troubleshooting, and to avoid occupying the vehicle's local storage space, a set of troubleshooting strategies for vehicle fault categories can be pre-built on the terminal or server and stored on the terminal or server.

[0111] For example, a set of troubleshooting strategies for air conditioning natural ventilation function failures can be pre-built on a personal computer (PC). For instance, a troubleshooting strategy for abnormal natural ventilation input command status could be: {Check the wiring harness between the air conditioning controller and the central control screen controller, and whether the central control screen operation is normal}; a troubleshooting strategy for abnormal power mode status could be: {Check whether the vehicle power supply and communication-related wiring harnesses are normal}; a troubleshooting strategy for abnormal recirculation damper motor status could be: {Check whether the wiring harness between the air conditioning controller and the motor, and the recirculation damper motor itself are normal}; and a troubleshooting strategy for abnormal blower status could be: {Check whether the blower wiring harness, blower power supply, and blower itself are normal}, etc.

[0112] In this way, when responding to a troubleshooting request, the system can request a set of troubleshooting strategies for the target fault from the terminal or server, and thus receive the set of troubleshooting strategies for the target fault sent by the terminal or server.

[0113] Step S1063: Based on the target status indication information, match the target troubleshooting strategy for the target fault from the troubleshooting strategy set.

[0114] Therefore, based on the target status indication information, the target fault troubleshooting strategy can be matched from the set of target fault troubleshooting strategies.

[0115] In step S1063 of some embodiments, in order to more accurately locate the target investigation strategy, the target status indication information can be compared with the investigation strategy set to determine the investigation strategy of the target status indication information based on the pre-built mapping relationship between the status indication information and the investigation strategy in the investigation strategy set; and the determined investigation strategy is used as the target investigation strategy.

[0116] The target status indication information is compared with the set of troubleshooting strategies corresponding to the target fault. Based on the pre-built mapping relationship between status indication information and troubleshooting strategies in the set of troubleshooting strategies corresponding to the target fault, the troubleshooting strategy corresponding to the target status indication information is found in the set of troubleshooting strategies corresponding to the target fault, and the found troubleshooting strategy is used as the target troubleshooting strategy.

[0117] Step S107: Perform troubleshooting on the target fault according to the target troubleshooting strategy.

[0118] Finally, the target faults were investigated according to the target troubleshooting strategy, thereby ensuring the accuracy of the troubleshooting results.

[0119] In step S107 of some embodiments, fault impact information of the target fault can be obtained according to the target troubleshooting strategy; and the fault troubleshooting of the target fault can be completed according to the fault impact information and the target fault time.

[0120] Based on the target troubleshooting strategy, the fault impact information of the target fault is determined, and then the fault impact information is integrated with the target fault time to obtain the troubleshooting results and complete the troubleshooting of the target fault.

[0121] For example, to improve the standardization of troubleshooting results, the fault impact information, target fault time, and target fault type can be filled into the corresponding fields in the preset troubleshooting result blank template to obtain the troubleshooting results, such as the air conditioning natural ventilation function failure caused by an abnormal blower wiring harness at around 23:59, which is convenient for troubleshooting personnel to view.

[0122] To better understand the above embodiments, the following are some application scenarios:

[0123] For example, in the event of a malfunction in the vehicle's air conditioning natural ventilation function, the fault time of 23:59 and the status indication information (including the prompt signal indicating that the natural ventilation input command status is normal, the prompt signal indicating that the power mode status is normal, the prompt signal indicating that the circulating damper motor status is normal, and the prompt signal indicating that the blower status is abnormal) are encoded according to the preset mapping rules to obtain the current status code "0000110111111011" corresponding to the air conditioning natural ventilation function malfunction; then the current status code "0000110111111011" is written into the preset storage partition corresponding to the air conditioning natural ventilation function malfunction.

[0124] Troubleshooters can trigger a troubleshooting request for a faulty air conditioning natural ventilation function. In response, the system first locates the target storage partition corresponding to the fault, then reads the target status code "0000110111111011" stored in that partition. According to a preset mapping rule, the system decodes the target status code "0000110111111011" to obtain the target fault time of 23:59 and the target status indication information (including normal natural ventilation input command status, normal power mode status, normal circulation damper motor status, and abnormal blower status). Next, the system identifies the target troubleshooting strategy for the abnormal blower status: {checking the blower wiring harness, blower power supply, and whether individual blower components are functioning correctly}. Then, based on this strategy, the system obtains fault impact information (such as abnormal blower wiring harness), ultimately determining that the air conditioning natural ventilation function fault occurred around 23:59 due to an abnormal blower wiring harness.

[0125] The vehicle fault diagnosis method provided in the above embodiments includes: obtaining the vehicle fault category; generating a current status code according to a preset mapping rule and the vehicle fault category; storing the current status code in a preset storage partition, wherein each preset storage partition is used to store the current status code for one vehicle fault category; responding to a diagnosis request for diagnosing a target fault, selecting a target storage partition for the target fault from the preset storage partitions; reading the current status code from the target storage partition and using the read current status code as the target status code for the target fault; determining a target diagnosis strategy for the target fault according to the preset mapping rule and the target status code; and diagnosing the target fault according to the target diagnosis strategy. On the one hand, by instantly generating the current status code of the vehicle fault category through preset mapping rules and storing it in a preset storage partition, timely capture and partition management of the current status data at the time of fault occurrence is realized. This not only provides a comprehensive and reliable basis for fault diagnosis but also ensures the identifiability, readableness, and ease of reading of the current status code. On the other hand, by determining the target storage partition of the target fault from the preset storage partition and reading the current status code stored in the target storage partition as the basis for analysis of the target fault, it helps to quickly and accurately locate the target fault and the applicable target diagnosis strategy. This enables reliable fault diagnosis of the target fault based on the target diagnosis strategy, effectively ensuring the accuracy of the fault diagnosis results.
