[0034] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0035] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0036] With the development of science and technology, smart cars are becoming more and more popular. A large amount of energy consumption data will be generated during the driving of smart cars, such as total mileage data, total driving time, and pure electric driving mileage. These energy consumption data are crucial for the operation, diagnosis and maintenance of vehicles.

[0037] Figure 1 The architecture diagram of a vehicle data storage system provided by an embodiment of the present application is shown as follows: Figure 1 As shown, a central control unit 110 (CUU) and an infotainment domain control unit (IDCU) 120 may exist in the vehicle data storage system 100, wherein the central control unit may include a first microcontroller unit (MCU) 111, a first memory 112, and a second memory 113. The first memory may be a non-volatile memory, for example, the first memory may be an electrically erasable programmable read-only memory (EEPROM); the second memory may be a volatile memory, for example, the second memory may be a random access memory (RAM). The IDCU may be used to count various energy consumption data during vehicle driving, for example, the IDCU may perform integral calculations based on the wheel number signal of the wheel to obtain the mileage of the vehicle. In addition, the central control unit and the IDCU may be connected via a controller area network (CAN) bus, so that the signal of the IDCU may be transmitted to the CCU for storage.

[0038] It can be understood that the above-mentioned RAM and EEPROM can be exemplary descriptions of volatile memory and non-volatile memory. Volatile memory can also include cache, registers, etc.; non-volatile memory can also include hard disk, solid state drive and Flash memory, etc. Therefore, the implementation of this application does not impose any restrictions on this.

[0039] However, in the related art, when the CUU stores data, the data may not be stored in the CUU because the vehicle is powered on immediately after being powered off, resulting in the loss of energy consumption data during the operation of the vehicle, causing inaccurate recording of the vehicle's energy consumption data, thereby affecting the operation, diagnosis and maintenance of the vehicle.

[0040] In order to solve the problems of the prior art, the embodiments of the present application provide a vehicle data storage method, device, vehicle and computer storage medium. The vehicle data storage method provided by the embodiments of the present application is first introduced below.

[0041] Figure 2 FIG. 1 is a flow chart of a vehicle data storage method provided by an embodiment of the present application. Figure 2 As shown, the vehicle data storage method includes the following steps:

[0042] S210: Determine the current working condition of the vehicle according to the power mode information and the network management information.

[0043] Exemplarily, the vehicle may include multiple power modes, and different power modes correspond to different states and / or operating conditions of the vehicle. In one example, the power mode may include a sleep mode, a standby (pre-ignition) mode, an ignition mode, and an operating mode.

[0044] For example, the network management information may be used to characterize the status of a CAN network in a vehicle.

[0045] When the vehicle is in sleep mode, the vehicle power is off and the CAN network is generally in sleep mode. When the vehicle is in standby mode, ignition mode, or running mode, the vehicle is powered on and the CAN network is generally awakened and can transmit signals.

[0046] For example, the current working condition of the vehicle can be obtained by acquiring the vehicle power status and CAN network status.

[0047] In one example, the current operating condition of the vehicle may be that the power is in sleep mode and the CAN network is in sleep mode; or, the current operating condition of the vehicle may be that the power is in sleep mode and the CAN network is not fully sleep.

[0048] Exemplarily, the MCU in the CUU may obtain the power mode information and the network management information, and determine the current working condition of the vehicle according to the power mode information and the network management information.

[0049] S220, matching the current working condition with a plurality of preset working conditions to determine a target working condition.

[0050] Exemplarily, relevant technical personnel may pre-formulate different working conditions according to different data storage requirements, wherein different working conditions include at least power status information and CAN network status information.

[0051] For example, the power state and CAN network state in the current working condition of the vehicle can be matched with each working condition in the preset working condition, and the working condition in the preset working condition that matches the current working condition is used as the target working condition.

[0052] In some optional embodiments, the multiple preset operating conditions include power-on switching conditions and operating conditions.

[0053] In one example, when it is detected that the power state is switched from the standby mode to the ignition mode, and the CAN network state is changed from the sleep state to the activated state, it can be determined that the current operating condition is the power-on switching operating condition.

[0054] In another example, when it is detected that the power state is the running mode and the CAN network state is the activated state, it can be determined that the current operating condition is the running condition.

[0055] S230. Determine a data storage process corresponding to the target operating condition according to the target operating condition.

[0056] Exemplarily, the target operating condition may be any one of a plurality of preset operating conditions, wherein the plurality of preset operating conditions include a power-on switching operating condition and an operating operating condition, and therefore, the target operating condition may be any one of the power-on switching operating condition and the operating operating condition.

[0057] Exemplarily, different target working conditions may correspond to different data storage processes.

[0058] In some optional embodiments, the data storage process corresponding to the power-on switching condition includes: determining first data to be stored based on first data obtained from the first controller, second data obtained from the second memory, and first historical data obtained from the first memory, and storing the first data to be stored in the first memory. The data storage process corresponding to the driving condition includes: determining second data to be stored based on temporary data obtained from the first controller, and storing the second data to be stored in the second memory.

[0059] S240, acquiring the data to be stored according to the data storage process corresponding to the target working condition, and storing the data to be stored in the target memory.

[0060] The target storage is determined based on the data storage process.

[0061] Exemplarily, the data to be stored may be determined according to the data storage process corresponding to the target working condition, and the data to be stored may be stored in the first memory or the second memory. The target memory may be any one of the first memory and the second memory.

[0062] In one example, the data to be stored may be stored in a non-volatile memory, such as an EEPROM. In another example, the data to be stored may be stored in a volatile memory, such as a RAM.

[0063] In the embodiment of the present application, the current working condition of the vehicle is determined through power mode information and network management information, and the current working condition is matched with multiple preset working conditions, so as to determine the target working condition and the data storage process corresponding to the target working condition, and then the data to be stored is obtained according to the target data storage process to realize data storage. It can be understood that in the embodiment of the present application, data can be stored in the target memory under different working conditions of the vehicle, so as to ensure that the data in the vehicle operation process can be completely and accurately obtained during the subsequent operation, diagnosis and maintenance of the vehicle, which is of great value for the normal operation and maintenance of the vehicle.

[0064] In order to realize data storage of power-on switching conditions, as another implementation method of the present application, the present application also provides another implementation method of the vehicle data storage method, please refer to the following embodiments for details.

[0065] Figure 3 FIG. 1 is a flow chart of a vehicle data storage method provided by an embodiment of the present application. Figure 3 As shown, the vehicle data storage method includes the following steps:

[0066] S310: Determine the current working condition of the vehicle according to the power mode information and the network management information.

[0067] S320, matching the current working condition with a plurality of preset working conditions to determine a target working condition.

[0068] S330. Determine a data storage process corresponding to the target operating condition according to the target operating condition.

[0069] Exemplarily, steps S310-S330 are consistent with steps S210-S230, and are not described in detail here. In the case where it is determined that the current operating condition of the vehicle is a power-on switching condition, it can be determined that the data storage process corresponding to the power-on switching condition is to determine the first data to be stored based on the first data obtained from the first controller, the second data obtained from the second memory, and the first historical data obtained from the first memory, and store the first data to be stored in the first memory.

[0070] S340: Acquire first data from the first controller.

[0071] Exemplarily, the first controller may be a controller for generating first data, wherein the first data may be energy consumption data.

[0072] In one example, the first controller may be an IDCU. After calculating the energy consumption data, the IDCU may broadcast the energy consumption data to a CAN bus, so that the CUU can obtain the energy consumption data through the CAN bus.

[0073] In some optional embodiments, the first data may include a plurality of data of different dimensions. Furthermore, after the first data is acquired from the first controller, validity checks may be performed on the plurality of data of different dimensions according to a preset priority order.

[0074] Exemplarily, the preset priority order can be set by a technician according to different requirements.

[0075] Exemplarily, when different data in the first data are verified in order of priority, the order of priority from high to low can be verified first, and the data of different dimensions in the first data can be verified.

[0076] In some optional embodiments, the different dimensional data may include at least total vehicle mileage data, total driving time data, vehicle identification code and pure electric driving mileage data, and the priority order of total vehicle mileage data may be set to the highest priority.

[0077] For example, technicians can also set higher priorities for data of other dimensions according to different needs, for example, the priority of the vehicle identification code can be set higher. It is understandable that the priority order of data of different dimensions in this application is only for illustrative purposes and is not specifically limited in this application.

[0078] In an embodiment of the present application, by setting the priority of each dimensional data in the first data and verifying the first data in order of priority, it is ensured that the validity of the data that the technicians believe to be relatively important can be confirmed earlier. This can improve the efficiency of data processing, reduce subsequent work delays and waste of resources due to important data errors, and provide a solid foundation for subsequent data storage.

[0079] S350: Acquire second data from the second memory.

[0080] Exemplarily, after the vehicle is powered on again, the second data in the volatile memory may be read, for example, the data currently stored in the RAM may be obtained.

[0081] S360: Acquire first historical data from the first memory.

[0082] Exemplarily, after the vehicle is powered on again, the first historical data in the non-volatile memory may be read, for example, the data currently stored in the EEPROM may be obtained.

[0083] S370: When it is determined that the data difference between the first historical data and the first data meets the preset synchronization condition, determine whether the data difference between the first data and the second data meets the preset synchronization condition, and if so, execute S380. If not, execute S390.

[0084] S380: Use the first data as first data to be stored, and store the first data to be stored in the first memory and the second memory.

[0085] S390: Use the second data as the first data to be stored, and store the first data to be stored in the first memory.

[0086] Exemplarily, when it is determined that the difference between the first historical data stored in the non-volatile memory and the first data in the first controller meets the preset synchronization condition, it can be determined whether the data difference between the first data in the first controller and the second data stored in the volatile memory meets the preset stop condition. If it is determined that the data difference between the first data in the first controller and the second data stored in the volatile memory meets the preset stop condition, step S380 can be executed, that is, the first data in the first controller is used as the first data to be stored, and the first data to be stored is stored in the first memory and the second memory respectively; if it is determined that the data difference between the first data in the first controller and the second data stored in the volatile memory does not meet the preset stop condition, step S390 can be executed, that is, the second data stored in the volatile memory is used as the first data to be stored, and the first data to be stored is stored in the first memory.

[0087] For example, Figure 4 A schematic diagram of a data storage process under a power-on condition provided by an embodiment of the present application is shown. Figure 4 As shown, first, step S401 can be executed to read the first historical data stored in the EEPROM and receive the first data sent by the IDCU, wherein the first data can be energy consumption data, and the energy consumption data includes total mileage data, VIN code, total driving time and pure electric driving mileage data. Further, step S402 is executed to check whether the first data can pass the cyclic redundancy check. If it is determined that the first data passes the cyclic redundancy check, step S403 can be executed to determine whether the total mileage data meets the preset mileage condition, for example, it can be determined whether the mileage data is greater than 500 kilometers.

[0088] Further, if it is determined that the preset mileage condition is met, step S404 may be executed, that is, whether the VIN code in the first data passes the verification. If it is determined that the VIN code in the first data passes the verification, step S405 is executed to verify whether the total mileage data is valid. If it is determined that the total mileage data is valid, step S406 is executed to synchronize the total mileage data to the RAM.

[0089] Furthermore, S407 is executed to check whether the total driving time is valid. If the total driving time is determined to be valid, step S408 is executed to store the total driving time in RAM. S409 is executed to check the pure electric mileage data. If the pure electric mileage data is determined to be valid, S410 can be executed to store the pure electric mileage data in RAM.

[0090] Further, step S411 may be executed to determine whether the power mode of the vehicle is switched from the sleep mode to the working mode, wherein the working mode includes at least the ignition mode and the running mode, and the vehicle is in the power-on state at this time, and the CAN network is awakened, and data transmission can be performed. If it is determined that the vehicle is in the working mode, S412 may be executed to determine whether the difference between the first data and the data in the EEPROM meets the preset synchronization condition. If it is determined that the difference between the first data and the data in the EEPROM meets the preset synchronization condition, S413 may be executed. If it is determined that the difference between the data in the RAM and the data in the EEPROM meets the preset synchronization condition, the data in the RAM may be stored in the EEPROM to achieve data storage.

[0091] In one example, data of different dimensions in the first data may be verified separately and stored in RAM respectively, and then the data to be stored may be stored in EEPROM through RAM.

[0092] In another example, when the data difference between the first data sent by the first controller and the RAM does not meet the preset synchronization condition, the data in the RAM may be stored in the EEPROM.

[0093] In the embodiment of the present application, after the vehicle is powered on again, the first data is obtained from the IDCU and compared with the data in the volatile memory, thereby determining the first data to be stored, and storing the first data to be stored in the non-volatile memory to achieve data synchronization. It can be understood that in the embodiment of the present application, after the vehicle is powered on, the CCU obtains the first data from the IDCU, and determines whether to re-update and store the data in the non-volatile memory in the CUU by the data stored in the volatile memory and the preset synchronization conditions. This can avoid the problem that the volatile memory is not stored in the non-volatile memory due to the power-on immediately after the vehicle is unloaded, ensuring that the energy consumption data of the vehicle can be stored in a timely and accurate manner, thereby ensuring the correctness of the data in the subsequent vehicle maintenance during the normal operation of the vehicle.

[0094] Furthermore, in order to achieve data synchronization of the IDCU, as another implementation method of the present application, the present application also provides another implementation method of the vehicle data storage method, please refer to the following embodiments for details.

[0095] Figure 5 FIG. 1 is a flow chart of a vehicle data storage method provided by an embodiment of the present application. Figure 5 As shown, the vehicle data storage method includes the following steps:

[0096] S501. Determine the current working condition of the vehicle according to the power mode information and the network management information.

[0097] S502: Match the current working condition with a plurality of preset working conditions to determine a target working condition.

[0098] S503: According to the target working condition, determine a data storage process corresponding to the target working condition.

[0099] S504: Acquire first data from the first controller.

[0100] S505: Acquire second data from the second memory.

[0101] S506: Acquire first historical data from the first memory.

[0102] S507: When it is determined that the data difference between the first historical data and the first data meets the preset synchronization condition, determine whether the data difference between the first data and the second data meets the preset synchronization condition, and if so, execute S508. If not, execute S509.

[0103] S508: Use the first data as first data to be stored, and store the first data to be stored in the first memory and the second memory.

[0104] S509: Use the second data as the first data to be stored, and store the first data to be stored in the first memory.

[0105] Exemplarily, steps S501-S509 are consistent with steps S310-S390, and will not be described in detail here.

[0106] S510: Acquire target data from the first memory.

[0107] Exemplarily, the target data may be acquired from the non-volatile memory, wherein the target data may refer to data currently stored in the first memory, ie, the non-volatile memory. For example, the target data may be data stored in an EEPROM.

[0108] Exemplarily, the target data may be first data to be stored that has been stored in the first memory.

[0109] Exemplarily, the MCU in the CUU may periodically read the data stored in the non-volatile memory. In one example, after storing the first data to be stored in the EEPROM, the MCU may periodically read the data stored in the EEPROM.

[0110] S511. Send target data to the first controller.

[0111] Exemplarily, after reading the data in the non-volatile memory, the MCU may broadcast the read data to the CAN bus, so that the first controller, ie, the IDCU, may receive the data through the CAN bus.

[0112] For example, Figure 6 A schematic diagram of a data storage process provided by an embodiment of the present application is shown. Figure 6 As shown, in step S601, the MCU in the CUU can periodically read the data in the EEPROM. Next, execute S602 to update the message to the data obtained from the EEPROM, and perform a validity check on the message. If the check is passed, step S603 can be executed to send the message to the CAN bus. Further, the IDCU can obtain the message through the CAN bus, and read and verify the data in the message. Furthermore, if the check is passed, the IDCU can determine whether the preset synchronization condition is met based on the data in the message and the data stored in itself. If it is determined that the preset synchronization condition is met, the IDCU can update its own data.

[0113] In one example, the IDCU may have a second microcontroller unit, a third memory, and a fourth memory. The third memory may be a non-volatile memory, for example, the third memory may be an electrically erasable programmable read-only memory (EEPROM); the fourth memory may be a volatile memory, for example, the fourth memory may be a random access memory (RAM). Furthermore, when the IDCU determines that the difference between the data stored in the third memory and the data in the message meets the preset synchronization condition, the data in the message may be updated to the third memory and / or the fourth memory.

[0114] In the embodiment of the present application, the MCU in the CUU broadcasts the data stored in the non-volatile memory, so that the data in the related components that interact with it can be synchronously updated. When the related components are replaced, it is ensured that they can obtain the correct historical data, thereby facilitating the replacement of components in the vehicle.

[0115] In order to realize data storage under driving conditions, as another implementation method of the present application, the present application also provides another implementation method of the vehicle data storage method, please refer to the following embodiments for details.

[0116] Figure 7 FIG. 1 is a flow chart of a vehicle data storage method provided by an embodiment of the present application. Figure 7 As shown, the vehicle data storage method includes the following steps:

[0117] S710: Determine the current operating condition of the vehicle according to the power mode information and the network management information.

[0118] S720: Match the current working condition with a plurality of preset working conditions to determine a target working condition.

[0119] S730. Determine a data storage process corresponding to the target operating condition according to the target operating condition.

[0120] Exemplarily, steps S710-S730 are consistent with steps S210-S230 and are not described in detail here. In particular, when it is determined that the current operating condition of the vehicle is a driving condition, the data storage process corresponding to the driving condition can be determined as determining the second data to be stored based on the second data obtained from the second memory, and storing the second data to be stored in the second memory.

[0121] S740: Receive temporary data.

[0122] Exemplarily, the temporary data may be temporary data sent by the IDCU via the CAN bus, wherein the temporary data may include energy consumption data to characterize data of the vehicle's driving process.

[0123] In one example, the energy consumption data includes at least total mileage data, vehicle identification number (VIN), total driving time, pure electric driving mileage, etc.

[0124] In one example, the IDCU can collect energy consumption data during vehicle driving and broadcast the energy consumption data to the CAN bus. The CUU can receive the energy consumption data sent by the IDCU through the CAN bus.

[0125] S750: Perform validity check on temporary data.

[0126] Exemplarily, after receiving the energy consumption data, the CUU may perform validity verification on the energy consumption data, thereby ensuring the validity of the data stored in the memory.

[0127] In one example, the data of various dimensions in the energy consumption data can be verified separately, and the VIN code in the energy consumption data can be verified to be consistent with the VIN code stored in the energy consumption data. Furthermore, the energy consumption data can be verified and compared by a checksum algorithm to ensure that there is no error or change in the energy consumption data during transmission.

[0128] S760: When it is determined that the temporary data verification has passed, the temporary data is stored in the second memory as second data to be stored.

[0129] Exemplarily, when it is determined that the energy consumption data verification has passed, the energy consumption data may be stored in the second memory.

[0130] In the embodiment of the present application, by receiving temporary data sent by the IDCU and performing validity verification on the temporary data, it is possible to ensure that the data stored in the volatile memory is valid data, that is, the data in the volatile memory is correct temporary data, so that the correctness of the data stored in the non-volatile memory can be guaranteed.

[0131] Furthermore, in order to realize data storage, as another implementation method of the present application, the present application also provides another implementation method of the vehicle data storage method, please refer to the following embodiments for details.

[0132] Figure 8 FIG. 1 is a flow chart of a vehicle data storage method provided by an embodiment of the present application. Figure 8 As shown, the vehicle data storage method includes the following steps:

[0133] S801. Determine the current working condition of the vehicle according to the power mode information and the network management information.

[0134] S802: Match the current working condition with a plurality of preset working conditions to determine a target working condition.

[0135] S803. According to the target working condition, determine a data storage process corresponding to the target working condition.

[0136] S804: Receive temporary data.

[0137] S805: Perform validity check on temporary data.

[0138] S806: When it is determined that the temporary data verification has passed, the temporary data is stored in the second memory as second data to be stored.

[0139] Exemplarily, steps S801-S806 are consistent with steps S710-S760, and are not described in detail here.

[0140] S807: When it is determined that the operating condition of the vehicle is switched to the power-off condition, obtain third data from the second memory.

[0141] Exemplarily, when it is detected that the vehicle power state switches from the running state or the ignition state to the sleep state, and the CAN network is in a completely sleep state, it can be determined that the current operating condition of the vehicle is the power-off condition.

[0142] Exemplarily, the third data may be read from the second memory by the MCU in the CUU, wherein the third data may be temporary data stored in the second memory, for example, the third data may be the second data to be stored that has been stored in the second memory.

[0143] In one example, the second memory may be a volatile memory, such as a RAM.

[0144] S808: Acquire second historical storage data from the first memory.

[0145] Exemplarily, the CUU may read the second historical storage data from the first memory through the MCU deployed in the CCU, wherein the second historical storage data may be the data currently stored in the first memory.

[0146] S809: When it is determined that the difference between the third data and the second historical storage data meets a preset synchronization condition, store the third data in the first memory.

[0147] Exemplarily, the preset synchronization condition may be a synchronization condition determined by a technician according to different requirements. In addition, different data synchronization conditions may correspond to data of different dimensions in the third data and the second historical data.

[0148] In one example, when there is total mileage data in both the second historical data and the third data, the preset synchronization condition can be set to determine whether the difference between the mileage value corresponding to the total mileage data in the third data and the mileage value corresponding to the total mileage data in the second historical data is greater than 10 kilometers. When it is determined whether the difference between the mileage value corresponding to the total mileage data in the third data and the mileage value corresponding to the total mileage data in the second historical data is greater than 10 kilometers, the total mileage data in the third data can be stored in the first memory.

[0149] For example, Fig. 9 A schematic diagram of a data storage process in a power-off sleep state provided by an embodiment of the present application is shown. Fig. 9 As shown, first, step S910 can be executed, that is, judging whether the vehicle is in a power-off condition. If it is determined that the vehicle is in a power-off condition, step S920 can be executed, that is, judging whether the RAM data in the CUU is updated. If it is determined that the data in the RAM is updated, step S930 is executed, that is, judging whether the difference between the data in the RAM and the data in the EEPROM meets the preset synchronization condition. If it is determined that the difference between the data in the RAM and the data in the EEPROM meets the preset synchronization condition, the invalid values ​​in the data in the RAM can be removed, and the data after the invalid values ​​are removed can be stored in the EEPROM to achieve data synchronization.

[0150] In the embodiment of the present application, when the power mode in the vehicle is in the power-off state and the CAN network state is in the dormant state, the data in the volatile memory is stored in the non-volatile memory, thereby avoiding data loss. In addition, by setting the preset synchronization condition, it is possible to ensure that the stored data avoids too many write operations to the non-volatile memory, which is beneficial to maintaining the life of the non-volatile memory.
