Abstract
Description
Technical Field
[0001] This application relates to the field of new energy vehicle technology, and in particular to a data processing method, apparatus and readable storage medium for a vehicle. Background Technology
[0002] The electric drive system is one of the core systems of new energy vehicles. Due to the complexity of its operating environment, electric drive failures occur frequently. Serious failures in the electric drive system can range from limiting the vehicle's speed and power to complete power loss and breakdown. Such serious failures pose a significant threat to driver safety and severely damage the manufacturer's reputation. Furthermore, because the electric drive system is a high-voltage system, serious failures are often accompanied by severe hardware problems such as burst pipes and damaged drive boards. Analyzing the fault symptoms remains a major challenge and pain point. Although electric drives possess diagnostic and freeze-frame functions, current fault diagnosis methods can only retrieve fault information, and freeze frames can store limited information with long processing times. Therefore, existing vehicle data processing methods suffer from technical problems such as low fault data integrity. Summary of the Invention

It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.
[0013] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. The term "two or more" includes two or more cases.
[0014] In some embodiments, such as Figure 1 As shown, an embodiment of this application provides a vehicle data processing method, including: Step S101: In the case of the motor controller failing for the first time, determine the fault level of the motor controller; Step S102: Under the condition that the fault level is greater than the preset level, based on the time of the fault occurrence of the motor controller, the first operating data of the motor controller during the sampling period is obtained. Step S103: Perform partitioning on the fault memory to determine the first partition in the fault memory; Step S104: Store the first running data in the first partition.
[0015] In this embodiment, a vehicle data processing method is proposed, wherein the vehicle includes a motor controller and a fault memory, the motor controller being a control device for the vehicle drive motor, and the fault memory being a storage device for storing vehicle fault information.
[0016] For example, the drive motor is the core power source of a vehicle, responsible for converting electrical energy into mechanical energy to drive the vehicle, while also recovering braking energy. During vehicle operation, the motor controller is used to control the drive motor in real time.
[0017] For example, during the use of motor controllers, serious malfunctions can occur due to equipment aging, unsuitable temperatures, or unreasonable hardware design. The most serious malfunction can damage the power module of the motor controller, resulting in anything from limited power or limpness in the entire vehicle to complete breakdown. There are many reasons for power module damage, such as overvoltage avalanche failure, overcurrent breakdown, and severe overheating. Moreover, when problems occur, it is often not a single fault, but a chain reaction that causes other faults to follow.
[0018] For example, the fault memory can be specifically a semiconductor memory, which has advantages such as high speed, large capacity and low cost.
[0019] When a motor controller fails for the first time, it is necessary to determine the fault level of the motor controller, which indicates the severity of the fault.
[0020] For example, the fault level can be specifically classified as a Level 1 fault, a Level 2 fault, or a Level 3 fault.
[0021] Level 3 faults are specifically defined as safety-related errors that may have a significant impact on the vehicle, requiring the vehicle to be stopped immediately.
[0022] Level 2 faults are specifically those errors that require immediate attention at a vehicle repair shop.
[0023] Level 1 faults are those that do not require immediate repair at a vehicle repair shop and can be addressed during vehicle maintenance.
[0024] For example, in the event of a Level 3 severe fault, the motor controller will activate its automatic waveform recording function to record key data before and after the first severe fault occurs, including but not limited to: system status, input and output signals, control commands, sensor data, etc. The motor controller will only be powered down after the data has been stored. This key data can be used to determine the cause of the motor controller failure.
[0025] Obtain the preset level, where the preset level is the threshold for determining the degree of fault in the motor controller.
[0026] For example, the preset level can be specifically a level two fault.
[0027] For example, if the fault level is greater than a preset level, it can be determined that the motor controller has a fault that endangers vehicle safety and requires immediate repair.
[0028] For example, if the fault level is less than or equal to a preset level, the fault in the motor controller can be determined to be a fault that does not require immediate repair.
[0029] When the fault level is greater than the preset level, the sampling period corresponding to the motor controller is determined based on the fault occurrence time of the motor controller, where the fault occurrence time is part of the sampling period.
[0030] For example, the sampling period includes the time when the fault occurs, covering both the time before and after the fault. Since data before a serious fault is more important for problem analysis, the sampling period covers the time before the fault occurs, ensuring the integrity of the sampling period's duration.
[0031] Acquire the first operating data of the motor controller during the sampling period, wherein the first operating data is the operating data of the motor controller during the sampling period.
[0032] For example, since the sampling period can cover the time before and after the fault, the first running data can also cover the running data before and after the fault, ensuring the integrity of the first running data and providing complete data support for subsequent fault diagnosis.
[0033] The fault memory is partitioned to determine the first partition in the fault memory and the first running data is stored in the first partition, wherein the first partition is the designated partition for storing the data corresponding to the first fault.
[0034] For example, the line selection method can be used to divide the first partition in the faulty memory. The line selection method directly uses the high-order address lines as chip select signals. It has the characteristics of simple wiring but possible address overlap, and is suitable for small-scale storage.
[0035] For example, a full decoding method can be used to divide the fault memory into a first partition. The full decoding method uses all the high-order address bits as the chip select signal, which has the characteristics of continuous address without overlap, but the decoding circuit is complex.
[0036] For example, a partial decoding method can be used to divide the fault memory into a first partition. The partial decoding method uses the high-order address part as the chip select signal. It has the advantages of possible address overlap, but the circuit is simpler than full decoding.
[0037] It should be noted that, under the condition that the fault level is greater than the preset level, this embodiment determines the sampling period that includes the time when the fault occurs, and obtains the first operating data of the motor controller within the sampling period. This ensures that the first operating data can cover the operating data before and after the fault occurs, thereby ensuring the integrity of the first operating data and providing complete data support for subsequent fault diagnosis.
[0038] In this embodiment, the vehicle data processing method determines the fault level of the motor controller when the motor controller fails for the first time. If the fault level is greater than a preset level, the method acquires the first operating data of the motor controller within the sampling period. Since the sampling period includes the time when the fault occurs, the data integrity of the first operating data is guaranteed.
[0039] In some embodiments, this application provides a vehicle data processing method that, based on the time of a motor controller failure, acquires first operating data of the motor controller during a sampling period, including: Based on the time of the fault occurrence, the sampling start time and sampling end time are determined, with the time of the fault occurrence falling between the sampling start time and the sampling end time. Based on the start time of sampling and the time of fault occurrence, determine the period before the fault, and based on the time of fault occurrence and the end time of sampling, determine the period after the fault. Acquire the pre-fault data of the motor controller during the period before the fault, and acquire the post-fault data of the motor controller during the period after the fault.
[0040] In this embodiment, the sampling period includes a pre-fault period and a post-fault period, and the first operating data includes pre-fault data and post-fault data. The pre-fault period is the period before the fault occurs, the post-fault period is the period after the fault occurs, the pre-fault data is the operating data before the fault occurs, and the post-fault data is the operating data after the fault occurs.
[0041] For example, the pre-fault period and the post-fault period are consecutive periods, and the connection point between the pre-fault period and the post-fault period is the time when the fault occurs.
[0042] For example, the pre-fault period can be specifically 150 sampling periods, the post-fault period can be specifically 50 sampling periods, and the sampling period can be specifically 10ms.
[0043] Based on the time of the fault occurrence, the sampling start time and sampling end time are determined, where the sampling start time is the beginning of the sampling and the sampling end time is the end of the sampling. The time of the fault occurrence is between the sampling start time and the sampling end time.
[0044] For example, the motor controller continuously outputs operating data during operation. The sampling start time is the time when the motor controller starts capturing the output operating data, and the sampling end time is the time when the motor controller stops capturing the output operating data.
[0045] Based on the start time of sampling and the time of the fault occurrence, the pre-fault period is determined, and based on the time of the fault occurrence and the end time of sampling, the post-fault period is determined.
[0046] Acquire the pre-fault data of the motor controller during the period before the fault, and acquire the post-fault data of the motor controller during the period after the fault.
[0047] For example, if the period before the fault is 150 sampling periods, the data before the fault is obtained for the 150 sampling periods before the fault.
[0048] For example, if the post-fault period is 50 sampling periods, the post-fault data for 50 sampling periods after the fault is obtained.
[0049] In some embodiments, this application provides a vehicle data processing method, which stores first operating data in a first partition, including: Obtain the first storage address and standard data structure of the first partition; The data structure of the first running data is converted into a standard data structure so that the first running data is updated to standardized data. Based on the first storage address, standardized data is stored in the first partition.
[0050] In this embodiment, the first storage address and standard data structure of the first partition are obtained, wherein the first storage address is the storage address in the first partition, and the standard data structure is a set data structure.
[0051] For example, the standard data structure is a table data structure, which uses an aligned structure to improve data access efficiency.
[0052] The data structure of the first running data is converted into a standard data structure so that the first running data is updated to standardized data, where standardized data is data with a unified structure.
[0053] For example, standardized data has a uniform data structure and is easy to write and read.
[0054] Based on the first storage address, standardized data is stored in the first partition.
[0055] In some embodiments of this application, a vehicle data processing method is provided, which, after storing first operating data in a first partition, further includes: In the event that the motor controller fails again, acquire the second operating data of the motor controller during the sampling period; Given that the fault memory includes a first partition, determine the second partition in the fault memory; Store the second running data in the second partition.
[0056] In this embodiment, if the motor controller fails again, the second operating data of the motor controller during the sampling period is obtained, wherein the second operating data is the operating data when the motor controller fails again.
[0057] For example, since the sampling period can cover the time before and after the fault, the second operating data can also cover the operating data before and after the fault, ensuring the integrity of the second operating data and providing complete data support for subsequent fault diagnosis.
[0058] Given that the fault memory includes a first partition, a second partition in the fault memory is determined, and the second operating data is stored in the second partition, wherein the second partition is used to store the operating data when the motor controller experiences the latest fault.
[0059] For example, the storage space of the faulty memory can be divided equally to obtain a first partition and a second partition.
[0060] In some embodiments, this application provides a vehicle data processing method that stores second operating data in a second partition, including: Obtain the second storage address and standard data structure of the second partition; The data structure of the second running data is converted into a standard data structure so that the second running data is updated to standardized data. Based on the second storage address, standardized data is stored in the second partition.
[0061] In this embodiment, the second storage address and standard data structure of the second partition are obtained, wherein the second storage address is the storage address in the second partition, and the standard data structure is a set data structure.
[0062] For example, the standard data structure is a table data structure, which uses an aligned structure to improve data access efficiency.
[0063] The data structure of the second running data is converted into a standard data structure so that the second running data is updated to standardized data.
[0064] For example, standardized data has a uniform data structure and is easy to write and read.
[0065] Based on the second storage address, standardized data is stored in the second partition.
[0066] In some embodiments of this application, a vehicle data processing method is provided, which, after storing the second operating data in a second partition, further includes: In the event that the motor controller fails again, acquire the third operating data of the motor controller during the sampling period; After clearing the data inside the second partition, the third runtime data is stored in the second partition.
[0067] In this embodiment, if the motor controller fails again, the third operating data of the motor controller during the sampling period is obtained, wherein the third operating data is the operating data when the motor controller failed most recently.
[0068] For example, since the sampling period can cover the time before and after the fault, the third operating data can also cover the operating data before and after the fault, ensuring the integrity of the third operating data and providing complete data support for subsequent fault diagnosis.
[0069] After clearing the data inside the second partition, the third runtime data is stored in the second partition.
[0070] For example, the second partition is used to store the operational data of the latest failure.
[0071] For example, a fault memory can write faults to non-volatile memory. The fault memory needs to ensure that it can store two sets of data, namely a first partition and a second partition.
[0072] The first partition needs to be stored according to the principle of first-to-first-triggered. When multiple serious failures occur at the same time, the critical data of the first level 3 failure will be stored. That is, once the failure matures, it will no longer be replaced by the data of other failures.
[0073] The fault storage data in the second partition is updated in real time. In the event of any level 3 fault, the fault storage data in the second partition will be flushed. That is, the fault storage data recorded in the second partition is always the latest fault data at the time of the serious fault.
[0074] In some embodiments of this application, a vehicle data processing method is provided, which, after storing first operating data in a first partition, further includes: Get the first storage address of the first partition; Based on the first storage address, read the first running data in the first partition.
[0075] In this embodiment, the first storage address of the first partition is obtained, and the first running data in the first partition is read based on the first storage address.
[0076] For example, after data storage, the stored data can be retrieved remotely or on-site based on the DID (Decentralized Identity) defined for each data point.
[0077] For example, the data format in the fault memory is shown in Table 1.
