[0044] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0045] The following describes a data storage method for a vehicle gateway, a data reading method for a vehicle gateway, a data storage device for a vehicle gateway, a data reading device for a vehicle gateway, and a computer-readable storage medium proposed in embodiments of the present invention with reference to the accompanying drawings.

[0046] Figure 1 The present invention is a flowchart of a data storage method of a vehicle gateway according to an embodiment of the present invention.

[0047] like Figure 1 As shown, the data storage method of the vehicle gateway of the embodiment of the present invention may include the following steps:

[0048] S101, obtaining a data update period of data to be stored.

[0049] In some embodiments of the present invention, the data update cycle may include data with a fast update speed and data with a slow update speed. For example, data with a fast update speed includes: dynamic routing table data and vehicle operation log data, etc., and data with a slow update speed includes: vehicle offline configuration data and vehicle operation fault data, etc.

[0050] S102: Determine a storage path for the data to be stored according to a data update period of the data to be stored.

[0051] Specifically, according to step S101, the data update cycle of the data to be stored can be obtained. When the data update cycle of the data to be stored is a fast update speed, the data with a fast update speed is stored in the internal memory because the reading time of the internal memory is faster; when the data update cycle of the data to be stored is a slow update speed, the reading time of the external memory is longer than that of the internal memory. Therefore, the data with a slow update speed is stored in the external memory. This can minimize the probability of memory read and write abnormalities caused by frequent data updates, thereby improving the overall stability of the gateway controller product.

[0052] According to one embodiment of the present invention, the vehicle gateway may include: an internal memory and an external memory, wherein the internal memory includes a first main storage area, the external memory includes a second main storage area, and the storage path of the data to be stored is determined according to the data update cycle of the data to be stored, including: when the data update cycle of the data to be stored is less than the set cycle, the data to be stored is stored in the first main storage area; when the data update cycle of the data to be stored is greater than or equal to the set cycle, the data to be stored is stored in the second main storage area. The set cycle can be set according to the data update cycle when the vehicle is produced and rolled off the assembly line.

[0053] In some embodiments of the present invention, the internal memory may be a non-volatile memory EEPROM (Electrically Erasable Programmable Read Only Memory) inside the MCU (Microcontroller Unit) controller of the vehicle gateway, and the external memory may be a non-volatile memory FLASH (flash memory) outside the controller. The MCU controller may control the reading and writing of the external FLASH memory via a bus.

[0054] Specifically, when the vehicle gateway stores data, the data to be stored first undergoes an integrity check, for example, a CRC (Cyclic Redundancy Check) check can be used to check the integrity of the data to be stored. When the data to be stored passes the check, the vehicle gateway starts to perform the data storage action; when the data to be stored fails the integrity check, the data storage fails.

[0055] If the data update cycle of the data to be stored is less than the set cycle, that is, the data to be stored is updated quickly, the data to be stored can be stored in the first main storage area of ​​the internal memory. Since the storage rate of the internal memory is fast, it can meet the high read and write requests of frequently updated data, thereby meeting the high read and write requests of frequently updated data, shortening the read and write operation time, and reducing the MCU execution time; if the data update cycle of the data to be stored is greater than or equal to the set cycle, that is, the data to be stored is updated slowly, the data to be stored can be stored in the second main storage area of ​​the external memory. Since the storage rate of the external memory is relatively slow, it is more suitable for storing data with a longer update cycle.

[0056] Therefore, the method classifies the data to be stored according to the update cycle and stores them in the internal memory and the external memory respectively. This can minimize the probability of memory read and write abnormalities caused by frequent data updates, thereby improving the overall stability of the gateway controller product.

[0057] According to an embodiment of the present invention, the internal memory further includes a first backup storage area, and after the data to be stored is successfully stored in the first main storage area, the method further includes: obtaining a data level of the data to be stored; when the data level of the data to be stored is a preset level, backing up the data to be stored in the first backup storage area; when the data to be stored is successfully backed up in the first backup storage area, determining that the data is successfully stored. In some embodiments of the present invention, the data level can be divided into important data and less important data according to the importance of the data to the vehicle, and the preset level can be important.

[0058] In some embodiments of the present invention, the vehicle gateway usually needs to store the following types of data: dynamic routing table data, vehicle offline configuration data, vehicle operation fault data and vehicle operation log data. Among them, the dynamic routing table data records the path of the gateway to route the message, determines the correctness of the gateway data routing, and is the most important data in the gateway storage data. This type of data will be frequently updated and adjusted according to the network load and the working conditions of other controllers, and the corresponding routing table also needs to be updated synchronously, so this type of data will be defined as important and updated faster. The vehicle offline configuration data is extremely important for vehicle operation. The configuration data directly defines the realization and performance indicators of vehicle functions, which is more intuitive for user experience; the configuration data is usually stored and written uniformly when the vehicle is offline, and is rarely updated in the future, unless there is a system upgrade, etc., so this type of data is defined as important and updated slower data. The vehicle operation fault data records the possible causes of the fault when the gateway function is limited, and provides an analysis basis for the future analysis of the fault, but the probability of vehicle failure is relatively low, the data update cycle is relatively long, and the loss of fault data will not have a substantial impact on the normal operation of the vehicle, so this type of data is defined as less important and updated slower data. The vehicle operation log data records the working status and environmental indicators of the gateway during daily operation, which is convenient for statistical analysis of the working conditions of the vehicle under various daily working conditions, and provides support for future performance optimization and updating of fault causes. This type of data will be updated frequently as the gateway works, but this type of data itself does not affect the normal function of the gateway, so this type of data is defined as less important and updated faster.

[0059] Specifically, after the data to be stored is successfully stored according to the update speed of the data to be stored, it is also determined whether to perform backup processing on the data to be stored according to the data level of the data to be stored. Among them, when the data to be stored is updated quickly and is important data, such as dynamic routing table data, the data to be stored is stored in the first main storage area of ​​the internal memory and backed up to the first backup storage area of ​​the internal memory. After the backup is successful, the data storage is considered successful; when the data to be stored is updated quickly but is not important data, such as vehicle operation log data, the data to be stored is stored in the first main storage area of ​​the internal memory, but is not backed up, and the data storage is considered successful. Therefore, by backing up important data, the reliability of important data storage is guaranteed, and by using the two-write method, the probability of encountering a busy device when writing data is reduced, the success rate of a single write is increased, the storage occupancy time is reduced, and the CPU execution efficiency is improved. Due to the increase in the success rate of a single write, multiple write attempts and waiting time are avoided.

[0060] According to an embodiment of the present invention, when the data to be stored is not successfully backed up to the first backup storage area, the method further includes: synchronizing the data to be stored stored in the first main storage area to the first backup storage area.

[0061] Specifically, when the data to be stored is not successfully backed up to the first backup storage area, the data to be stored stored in the first main storage area is synchronized to the first backup storage area. The process of synchronizing the data to be stored in the first main storage area to the first backup storage area is: reading the data to be stored in the first main storage area, verifying the integrity of the data, and if the data is complete, synchronizing the data to the first backup storage area. Thus, the reliability of important data is guaranteed by performing a real-time redundant backup mechanism for important data.

[0062] According to one embodiment of the present invention, when the data to be stored is not successfully stored in the first main storage area, the method also includes: if the data level of the data to be stored is not a preset level, determining that the data storage has failed; if the data level of the data to be stored is a preset level, storing the data to be stored in the first backup storage area; when the data to be stored is successfully stored in the first backup storage area, synchronizing the data to be stored stored in the first backup storage area to the first main storage area.

[0063] Specifically, when the data to be stored is not successfully stored in the first main storage area, it is necessary to judge the data level of the data to be stored. If the data level of the data to be stored is secondary importance, it means that the loss of the data will not have a substantial impact on the normal operation of the vehicle gateway, and there is no need to continue storing the data, and the data storage fails.

[0064] If the data to be stored is important data, the data to be stored is first stored in the first backup storage area. After the data to be stored is successfully stored in the first backup storage area, the data to be stored stored in the first backup storage area is synchronized to the first main storage area. The specific process of synchronizing the data to be stored in the first backup storage area to the first main storage area is: read the data to be stored in the first backup storage area, check the integrity of the data, and if the data is complete, synchronize the data to the first main storage area. In this way, the automatic recovery of erroneous data is achieved through the redundant storage of gateway data and the data synchronization mechanism.

[0065] According to one embodiment of the present invention, the data storage method of the above-mentioned vehicle gateway further includes: when the data to be stored in the first main storage area is consistent with the data to be stored in the first backup storage area, determining that the synchronization of the data to be stored is successful; when the data to be stored in the first storage area is inconsistent with the data to be stored in the first backup storage area, determining that the synchronization of the data to be stored has failed.

[0066] Specifically, in the aforementioned embodiment, during the storage process of the data to be stored, if the data to be stored is important and updated quickly, it is necessary to store it twice in the first main storage area and the first backup storage area, and in the case that the data to be stored is only successfully stored once during the storage process, the data in the storage area storing the data to be stored is synchronized to the storage area that failed to complete. After synchronizing the band storage data, it is also necessary to compare the data to be stored in the first main storage area with the data to be stored in the first backup storage area for consistency. When the data to be stored in the first main storage area is consistent with the data to be stored in the first backup storage area, it is determined that the synchronization of the data to be stored is successful; when the data to be stored in the first storage area is inconsistent with the data to be stored in the first backup storage area, it is determined that the synchronization of the data to be stored has failed. Therefore, by performing consistency verification on the data in the storage area and the data in the backup area, the accuracy of data storage can be improved.

[0067] According to one embodiment of the present invention, the external memory also includes a second backup storage area. After the data to be stored is successfully stored in the second main storage area, the method also includes: obtaining the data level of the data to be stored; when the data level of the data to be stored is a preset level, backing up the data to be stored to the second backup storage area; when the data to be stored is successfully backed up to the second backup storage area, determining that the data storage is successful.

[0068] According to an embodiment of the present invention, when the data to be stored is not successfully backed up to the second backup storage area, the method further includes: synchronizing the data to be stored stored in the second main storage area to the second backup storage area.

[0069] Specifically, after the data to be stored is successfully stored according to the update speed of the data to be stored, it is also determined whether to perform backup processing on the data to be stored according to the data level of the data to be stored. Among them, when the data to be stored is updated slowly and is important data, such as vehicle offline configuration data, the data to be stored is stored in the second main storage area of ​​the external memory and backed up to the second backup storage area of ​​the external memory. After the backup is successful, the data storage is considered successful; when the data to be stored is updated slowly but is not important data, such as vehicle operation fault data, the area to be stored is stored in the second main storage area of ​​the external memory, but a backup is performed, and the data storage is considered successful. Therefore, by backing up important data, the reliability of important data storage is guaranteed, and by using a two-time write method, the probability of encountering a busy device when writing data is reduced, the success rate of a single write is increased, the storage occupancy time is reduced, and the CPU execution efficiency is improved. Due to the increase in the success rate of a single write, multiple write attempts and waiting time are avoided.

[0070] When the data to be stored is not successfully backed up to the second backup storage area, the data to be stored stored in the second main storage area is synchronized to the second backup storage area. The process of synchronizing the data to be stored in the second main storage area to the second backup storage area is: reading the data to be stored in the second main storage area, checking the integrity of the data, and if the data is complete, synchronizing the data to the second backup storage area. Thus, the reliability of important data is guaranteed by performing a real-time redundant backup mechanism for important data.

[0071] According to one embodiment of the present invention, when the data to be stored is not successfully stored in the second main storage area, the method also includes: if the data level of the data to be stored is not a preset level, determining that the data storage has failed; if the data level of the data to be stored is a preset level, storing the data to be stored in the second backup storage area; when the data to be stored is successfully stored in the second backup storage area, synchronizing the data to be stored stored in the second backup storage area to the second main storage area.

[0072] Specifically, when the data to be stored is not successfully stored in the second main storage area, it is necessary to judge the data level of the data to be stored. If the data level of the data to be stored is secondary importance, it means that the loss of the data will not have a substantial impact on the normal operation of the vehicle gateway, and there is no need to continue storing the data, and the data storage fails.

[0073] If the data to be stored is important data, the data to be stored is first stored in the second backup storage area. After the data to be stored is successfully stored in the second backup storage area, the data to be stored stored in the second backup storage area is synchronized to the second main storage area. The specific process of synchronizing the data to be stored in the second backup storage area to the second main storage area is: reading the data to be stored in the second backup storage area, checking the integrity of the data, and if the data is complete, synchronizing the data to the second main storage area. Thus, through the redundant storage of gateway data and the data synchronization mechanism, automatic recovery of erroneous data is achieved.

[0074] According to one embodiment of the present invention, the data storage method of the above-mentioned vehicle gateway further includes: when the data to be stored in the second main storage area is consistent with the data to be stored in the second backup storage area, determining that the synchronization of the data to be stored is successful; when the data to be stored in the second storage area is inconsistent with the data to be stored in the second backup storage area, determining that the synchronization of the data to be stored has failed.

[0075] Specifically, in the aforementioned embodiment, during the storage process of the data to be stored, if the data to be stored is important and updated slowly, it is necessary to store it twice in the second main storage area and the second backup storage area, and in the case that the data to be stored is only successfully stored once during the storage process, the data in the storage area storing the data to be stored is synchronized to the storage area that failed to complete. After synchronizing the band storage data, it is also necessary to compare the data to be stored in the second main storage area with the data to be stored in the second backup storage area for consistency. When the data to be stored in the second main storage area is consistent with the data to be stored in the second backup storage area, it is determined that the synchronization of the data to be stored is successful; when the data to be stored in the second storage area is inconsistent with the data to be stored in the second backup storage area, it is determined that the synchronization of the data to be stored has failed. Therefore, by performing consistency verification on the data in the storage area and the data in the backup area, the accuracy of data storage can be improved.

[0076] As a specific example, Figure 2 As shown, the data storage process in the data storage method of the vehicle gateway may include the following steps:

[0077] S201, start storing data.

[0078] S202, perform integrity check to determine whether the data to be stored is complete. If yes, execute step S204; if not, execute step S203.

[0079] S203, data storage fails.

[0080] S204, determine whether the data update period of the data to be stored is less than the set period. If yes, execute step S205; if not, execute step S206.

[0081] S205: Store the data to be stored in the first main storage area.

[0105] It should be noted that the details of the data synchronization process in the external memory of the vehicle gateway can refer to the data synchronization process in the internal memory, which will not be repeated here.

[0106] In summary, according to the data storage method of the vehicle gateway of the embodiment of the present invention, when storing data, the data update cycle of the data to be stored is first obtained, and then the storage path of the data to be stored is determined according to the data update cycle of the data to be stored. Therefore, the method classifies and stores the data to be stored according to the type of data to be stored, reducing the probability of abnormal reading and writing of the memory caused by frequent data updates, thereby improving the reliability of the vehicle gateway in complex environments and improving the overall stability of the vehicle gateway.

[0107] In order to clearly explain the above embodiment, a second aspect of the present invention provides a method for reading data from a vehicle-mounted gateway. Figure 4 This is a flowchart of a method for reading data from an in-vehicle gateway provided in an embodiment of the second aspect of the present application.

[0108] like Figure 4 As shown, the data reading method of the vehicle gateway may include the following steps:

[0109] S401, executing the data storage method of the vehicle gateway of the first aspect embodiment to determine the storage data.

[0110] S402, when a data read instruction is received, determining a data update period of the data to be read according to the data read instruction.

[0111] S403, determining a reading path of the data to be read according to a data update period of the data to be read.

[0112] According to one embodiment of the present invention, the vehicle gateway includes: an internal memory and an external memory, wherein the internal memory includes a first main storage area, the external memory includes a second main storage area, and a reading path of the data to be read is determined according to a data update cycle of the data to be read, including: when the data update cycle of the data to be read is less than a set cycle, determining to read the data from the first main storage area; when the data update cycle of the data to be read is greater than or equal to the set cycle, determining to read the data from the second main storage area.

[0113] Specifically, if the data update cycle of the data to be read is less than the set cycle, that is, the data to be read is updated quickly, the data can be read from the first main storage area of ​​the internal memory. Since the reading rate of the internal memory is fast, it can meet the high read and write requests of frequently updated data, thereby shortening the read and write operation time and reducing the execution time of the on-board gateway MCU.

[0114] If the data update cycle of the data to be read is greater than the set cycle, that is, the data to be read is updated slowly, the data storage can be read from the second main storage area of ​​the external memory. Since the reading rate of the external memory is relatively slow, it is more suitable for reading and writing data with a longer update cycle, thereby reducing the risk of data loss caused by frequent operations.

[0115] According to one embodiment of the present invention, the internal memory also includes a first backup storage area. After successfully reading data from the first main storage area, the method also includes: obtaining a data level of the data to be read; when the data level of the data to be read is a preset level, reading the data from the first backup storage area; when successfully reading the data from the first backup storage area, if the data read from the first main storage area is the same as the data read from the first backup storage area, determining that the data reading is successful.

[0116] Specifically, after successfully reading data from the first main storage area according to the update speed of the data to be read, it is also determined whether to read the data from the first backup storage area according to the data level of the data to be read. Among them, when the data to be read is updated quickly and is important data, such as dynamic routing table data, after successfully reading the data from the first main storage area of ​​the internal memory, the data is also read from the first backup storage area of ​​the internal memory. After the data is read successfully, the data read from the first main storage area is compared with the data read from the first backup storage area for consistency. If the two are the same, the vehicle gateway successfully reads the data. When the data to be read is updated quickly but is not important data, such as vehicle operation log data, after successfully reading the data from the first main storage area of ​​the internal memory, there is no need to read the data from the first backup storage area, and the data is considered to be read successfully. Therefore, the accuracy of data reading is improved by reading and verifying twice.

[0117] According to one embodiment of the present invention, the external memory also includes a second backup storage area. After successfully reading data from the second main storage area, the method also includes: obtaining a data level of the data to be read; when the data level of the data to be read is a preset level, reading the data from the second backup storage area; when successfully reading data from the second backup storage area, if the data read from the second main storage area is the same as the data read from the second backup storage area, determining that the data reading is successful.

[0118] Specifically, after successfully reading data from the second main storage area according to the update speed of the data to be read, it is also determined whether to read the data from the second backup storage area according to the data level of the data to be read. Among them, when the data to be read is updated quickly and is important data, such as dynamic routing table data, after successfully reading the data from the second main storage area of ​​the internal memory, the data is also read from the second backup storage area of ​​the internal memory. After the data is read successfully, the data read from the second main storage area is compared with the data read from the second backup storage area for consistency. If the two are the same, the vehicle gateway successfully reads the data. When the data to be read is updated quickly but is not important data, such as vehicle operation log data, after successfully reading the data from the second main storage area of ​​the internal memory, there is no need to read the data from the second backup storage area, and the data is considered to be read successfully. Therefore, the accuracy of data reading is improved by reading and verifying twice.

[0119] As a specific example, Figure 5 As shown, the process of the data reading method of the vehicle gateway may include the following steps:

[0120] S501, receiving a data read instruction.

[0121] S502, determining a data update period of the data to be read according to the data reading instruction.

[0122] S503, determining a reading path according to an update period of the data to be read.

[0123] S504, perform integrity check to determine whether the data to be read is complete. If yes, execute step S505; if not, execute step S509.

[0124] S505, determining whether the data level of the data to be stored is a preset level. If yes, executing step S506; if no, executing step S508.

[0125] S506, reading data from the corresponding backup storage area.

[0126] S507, determine whether the data to be read in the primary storage area is consistent with the data to be read in the corresponding backup storage area. If yes, execute step S508; if not, execute step S512.

[0127] S508, data read successfully

[0128] S509, determine whether the data level of the data to be stored is a preset level. If yes, execute step S510; if not, execute step S513.

[0129] S510, reading data from a corresponding backup storage area.

[0130] S511, perform integrity check to determine whether the data to be stored is complete. If yes, execute step S512; if not, execute step S513.

[0131] S512, enter the data synchronization process.

[0132] S513, data reading failed.
