[0059] The embodiment of the present application provides a vehicle fault troubleshooting method, device, vehicle and storage medium. The technical solution of the present application 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 of a vehicle fault category; in response to a troubleshooting request for troubleshooting a target fault, filtering out a target storage partition of a target fault from the preset storage partition; reading the current status code from the target storage partition, and using the read current status code as the target status code of the target fault; determining a target troubleshooting strategy for the target fault according to the preset mapping rule and the target status code; troubleshooting the target fault according to the target troubleshooting strategy.

[0060] The embodiment of the present application provides a vehicle fault troubleshooting method, which relates to the field of fault handling technology. The vehicle fault troubleshooting method provided in the embodiment of the present application can be applied to a vehicle, or it can be software running in a vehicle. The vehicle can be a private car, such as a sedan, SUV, MPV or pickup truck. The vehicle can also be an operating vehicle, such as a van, bus, small truck or large trailer. The vehicle can be a fuel 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 troubleshooting method, etc., but is not limited to the above forms.

[0061] Reference Figure 1 The embodiment of the present application provides a vehicle fault troubleshooting method, which may include but is not limited to steps S101 to S107, as follows:

[0062] Step S101: Obtain vehicle fault category.

[0063] For example, the vehicle may have multiple types of faults, such as air conditioning system fault (such as failure of the natural ventilation function of the air conditioning), navigation system fault, sensor system fault, etc. In the case of a vehicle fault, the vehicle fault category is obtained.

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

[0065] The current status code is generated instantly according to the preset mapping rules and vehicle fault categories. Thus, the real-time status data of the fault category occurrence time can be captured and managed in a timely manner, providing an effective and reliable analysis basis for troubleshooting.

[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 is obtained, wherein the status indication information is a prompt signal for indicating the current status of the vehicle fault category; the fault time and the status indication information are encoded according to preset mapping rules to obtain the current status code.

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

[0068] The state indication information refers to a prompt signal for indicating the current state of the time when the vehicle fault category occurs. It can be understood that the state indication information of the vehicle fault category at least includes a prompt signal indicating that the current state is abnormal.

[0069] For example, taking the failure of the natural ventilation function of the air conditioner as an example, the status indication information corresponding to the failure of the natural ventilation function of the air conditioner may include a prompt signal of the natural ventilation input command state, a prompt signal of the power mode state, a prompt signal of the circulation damper motor state, and a prompt signal of the blower state. Then, assuming that the natural ventilation function of the air conditioner fails in the vehicle, at least one of the prompt signal of the natural ventilation input command state, the prompt signal of the power mode state, the prompt signal of the circulation damper motor state, and the prompt signal of the blower state is a prompt signal of abnormal state.

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

[0071] The current status code refers to a digital code used to characterize the fault time and real-time status of the vehicle fault category. The size of the current status code can be flexibly set according to demand and is not limited to this.

[0072] The preset mapping rule refers to a preset rule that can convert the fault time and status indication information of the vehicle fault category into the current status code of the vehicle fault category. It should be noted that the preset mapping rule can reversely restore the current status code to the fault time and status indication information of the vehicle fault category.

[0073] Exemplarily, for example, the preset mapping rule may be to convert the fault time and status indication information of the vehicle fault category into a 16-digit digital code. In order to ensure the identifiability of the current status code, each digit from the 1st to the 5th digit may be defined to represent one of the real-time states corresponding to the fault (such as defining the 5th digit to represent the blower state, the 4th digit to represent the circulating damper motor state, the 3rd digit to represent the power mode state, the 2nd digit to represent the natural ventilation input command state and the 1st digit to represent the remaining real-time states corresponding to the fault, wherein the digit 0 is used to represent the normal state and the digit 1 is used to represent the abnormal state); it is understandable that in order to reduce the storage space occupied by the storage of the current status code, the occurrence time may be simplified to a fixed value, such as representing the fault time "23:59" in binary to obtain "101111111011", thus defining the 6th to the 16th digits to represent the fault time.

[0074] Taking the example of a vehicle with an air conditioning natural ventilation function failure at "23:59", the status indication information corresponding to the air conditioning natural ventilation function failure includes a prompt signal that the natural ventilation input command status is normal, a prompt signal that the power mode status is normal, a prompt signal that the circulating damper motor status is normal, and a prompt signal that the blower status is abnormal. Then the current status code corresponding to the air conditioning natural ventilation function failure is such as "0000110111111011".

[0075] In this way, by encoding the fault time and status indication information of the vehicle fault category into the current status code, the complex current status indication information can be converted into a short current status code, which is not only convenient for storage and management, but also can provide timely, effective, comprehensive and reliable analysis basis for identifying and locating faults, thus laying the foundation for effectively responding to fault troubleshooting.

[0076] Step S103: storing 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 of the vehicle fault category, the current status code of the vehicle fault category is stored in a preset storage partition corresponding to the vehicle fault category to implement partition management of the current status code of the vehicle fault category and ensure the readability and convenience of the current status code.

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

[0079] Specifically, a specific storage area of ​​a certain size may be preset in the local memory of the vehicle for storing the current status code. In order to achieve reasonable use of the specific storage area and improve the utilization rate of the specific storage area, the specific storage area may be divided into multiple storage partitions (defined as preset storage partitions).

[0080] In order to distinguish which vehicle fault category each preset storage partition is used to store the current status code of, each preset storage partition can be identified, such as using the letter "E" to identify the preset storage partition used to store the current status code of the air-conditioning natural ventilation function failure, and using the letter "G" to identify the preset storage partition used to store the current status code of the navigation system failure.

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

[0082] Exemplarily, in order to avoid occupying too much of the vehicle's local memory, for example, a 1k storage space can be preset in the vehicle's local memory. The 1k storage space contains 1024 bytes. Multiple bytes can be used as a preset storage partition to store the current status code of a vehicle fault category respectively. For example, 2 bytes are used as a preset storage partition, and the 1st to 5th bits of the 16 bits of the 2 bytes represent one of the real-time states of the vehicle fault category, and the last 11 bits represent the occurrence time of the vehicle fault category.

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

[0084] As a result, timely capture and reasonable management of real-time status data at the time of fault occurrence are achieved.

[0085] It is understandable that each preset storage partition has good scalability and can increase space, and there is no limit on the space size of the preset storage partition.

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

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

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

[0089] Step S202: Detect the usable status of the preset storage partition according to the available capacity.

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

[0091] Exemplarily, for example, a capacity threshold (defined as a preset threshold) can be set in advance to determine whether the available capacity of the preset storage partition reaches the preset threshold. When the available capacity reaches the preset threshold, the usable state is determined to be that the preset storage partition is unusable.

[0092] Step S203: If the available status indicates that the preset storage partition is unavailable, the storage order of the current status codes of the preset storage partition is obtained.

[0093] When the available state indicates that the preset storage partition is unavailable, the storage order of the current state codes stored in the preset storage partition is obtained.

[0094] Step S204: According to the storage order, select candidate status codes from the current status codes of the preset storage partition, wherein the candidate status codes are status codes that need to be deleted.

[0095] According to the storage order, the candidate status codes to be deleted are filtered out from the current status codes of the preset storage partition.

[0096] Step S205: Delete the candidate status code.

[0097] Finally, the candidate status code is deleted.

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

[0099] In this way, the rolling update storage of the current status code is realized, which saves the space of the preset storage partition and ensures that the preset storage partition always retains the latest stored real-time status code, thereby providing the latest analysis basis for rapid identification for troubleshooting.

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

[0101] A user such as a troubleshooter may trigger a troubleshooting request for troubleshooting a target fault, so that, in response to the troubleshooting request, the target storage partition of the target fault is first 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 of the target fault.

[0103] The current status code stored in the target storage partition is read, and the read current status code is used as the target status code of the target fault.

[0104] Step S106: Determine a target troubleshooting strategy for the target fault according to the preset mapping rule and the target status code.

[0105] Afterwards, a target troubleshooting strategy for the target fault is determined based on the preset mapping rules and the target status code.

[0106] Reference Figure 3 In order to locate the target troubleshooting strategy more quickly and accurately 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 a preset mapping rule, the target status code is decoded to obtain target fault time and target status indication information of the target fault.

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

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

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

[0111] Exemplarily, for example, a set of troubleshooting strategies for air-conditioning natural ventilation function failures can be pre-built on a personal computer (PC), such as the troubleshooting strategy for abnormal natural ventilation input command status = {check whether the wiring harness between the air-conditioning controller and the central control screen controller and the operation of the central control screen are normal}; the troubleshooting strategy for abnormal power mode status = {check whether the vehicle power supply and communication-related wiring harnesses are normal}; the troubleshooting strategy for abnormal circulating damper motor status = {check whether the wiring harness between the air-conditioning controller and the motor and the circulating damper motor are normal}; the troubleshooting strategy for abnormal blower status = {check whether the blower wiring harness, blower power supply, and blower single unit are normal}, etc.

[0112] In this way, when responding to the troubleshooting request, the terminal or server may be requested to provide a set of troubleshooting strategies for the target fault, thereby receiving the set of troubleshooting strategies for the target fault sent by the terminal or server.

[0113] Step S1063: According to the target state indication information, a target troubleshooting strategy for the target fault is matched from the troubleshooting strategy set.

[0114] Therefore, the target troubleshooting strategy for the target fault can be matched from the target fault troubleshooting strategy set according to the target state indication information.

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

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

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

[0118] Finally, the target fault is troubleshooted 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 may be obtained according to the target troubleshooting strategy; and the troubleshooting of the target fault may be completed according to the fault impact information and the target fault time.

[0120] The fault impact information of the target fault is determined according to the target troubleshooting strategy, so as to integrate the fault impact information with the target fault time, obtain the troubleshooting result, and complete the troubleshooting of the target fault.

[0121] For example, in order to improve the standardization of the troubleshooting results, the fault impact information, target fault time and target fault type can be filled in the corresponding filling items in the preset troubleshooting result blank template to obtain the troubleshooting results. For example, at around 23:59, the vehicle's air conditioning natural ventilation function failed due to an abnormality in the blower wiring harness, which is convenient for troubleshooters to check.

[0122] To better understand the above embodiment, the following application scenarios are given as examples:

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

[0124] The troubleshooting personnel can trigger a troubleshooting request for the natural ventilation function failure of the air conditioner. In this way, in response to the troubleshooting request for the natural ventilation function failure of the air conditioner, the target storage partition corresponding to the natural ventilation function failure of the air conditioner is first located, and then the target status code "0000110111111011" stored in the target storage partition is read, and the target status code "0000110111111011" is decoded according to the preset mapping rule to obtain the target fault time 23:59 and target status indication information corresponding to the natural ventilation function failure of the air conditioner (including normal natural ventilation input instruction status, normal power mode status, normal circulation damper motor status and abnormal blower status), and then locate the target troubleshooting strategy for the abnormal blower status: {check whether the blower wiring harness, blower power supply and single blower are normal}, and then obtain the fault impact information (such as abnormal blower wiring harness) based on the target troubleshooting strategy for the abnormal blower status, and finally obtain the troubleshooting result that the natural ventilation function failure of the vehicle caused by the abnormal blower wiring harness at around 23:59.

[0125] The vehicle fault troubleshooting method provided in the above embodiment obtains the vehicle fault category; generates a current status code according to a preset mapping rule and the vehicle fault category; stores the current status code in a preset storage partition, wherein each preset storage partition is used to store the current status code of a vehicle fault category; in response to a troubleshooting request for troubleshooting a target fault, filters out a target storage partition for the target fault from the preset storage partition; reads the current status code from the target storage partition, and uses the read current status code as the target status code for the target fault; determines a target troubleshooting strategy for the target fault according to the preset mapping rule and the target status code; and troubleshoots the target fault according to the target troubleshooting strategy. On the one hand, the current status code of the vehicle fault category is instantly generated through preset mapping rules and stored in the preset storage partition, which realizes the timely capture and partition management of the current status data at the time of fault occurrence, which can not only provide a comprehensive and reliable analysis basis for fault troubleshooting, but also ensure the identifiability, readability 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 analysis basis of the target fault, it is helpful to quickly and accurately locate the target troubleshooting strategy applicable to the target fault, and realize reliable troubleshooting of the target fault quickly and appropriately based on the target troubleshooting strategy, which can effectively ensure the accuracy of the troubleshooting results.
