Referring to fig. 1, fig. 1 is a schematic structural diagram of an automobile configuration refreshing device in a hardware running environment according to an embodiment of the present invention.
As shown in fig. 1, the car configuration flashing device may include: a processor 1001, such as a central processing unit (Central Processing Unit, CPU), a communication bus 1002, a user interface 1003, a network interface 1004, a memory 1005. Wherein the communication bus 1002 is used to enable connected communication between these components. The user interface 1003 may include a Display, an input unit such as a Keyboard (Keyboard), and the optional user interface 1003 may further include a standard wired interface, a wireless interface. The network interface 1004 may optionally include a standard wired interface, a Wireless interface (e.g., a Wireless-Fidelity (Wi-Fi) interface). The Memory 1005 may be a high-speed random access Memory (Random Access Memory, RAM) Memory or a stable Non-Volatile Memory (NVM), such as a disk Memory. The memory 1005 may also optionally be a storage device separate from the processor 1001 described above.
It will be appreciated by those skilled in the art that the structure shown in fig. 1 is not limiting of an automotive configuration brush device and may include more or fewer components than shown, or certain components may be combined, or a different arrangement of components.
As shown in fig. 1, an operating system, a data storage module, a network communication module, a user interface module, and an automobile configuration brush program may be included in the memory 1005 as one type of storage medium.
In the automobile configuration flash device shown in fig. 1, the network interface 1004 is mainly used for data communication with other devices; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the automobile configuration flashing device of the present invention may be provided in the automobile configuration flashing device, where the automobile configuration flashing device invokes an automobile configuration flashing program stored in the memory 1005 through the processor 1001, and executes the automobile configuration flashing method provided by the embodiment of the present invention.
The embodiment of the invention provides an automobile configuration refreshing method, referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the automobile configuration refreshing method.
In this embodiment, the method for brushing automobile configuration includes:
step S10: and carrying out safety verification on the current vehicle configuration information.
It should be noted that, whether the vehicle carries out the writing by using a writing tool or by using an external device, the safety verification is required, and only after the verification is passed, the writing communication path related to the part to be written is opened.
It can be understood that before updating the configuration information, each ECU in the vehicle needs to confirm whether the source of the update information is legal through an encryption algorithm, each ECU stores an agreed key (public key or private key), the meter and the vehicle-mounted terminal encrypt (sign) related information through the key (public key), the receiving end decrypts the encrypted information through the private key (private key) and confirms whether the signature of the update information is legal, on the other hand, because the vehicle-mounted terminal or the dashboard stores a backup of the vehicle configuration information, if the vehicle-mounted terminal or the dashboard is updated, the vehicle-mounted terminal or the dashboard needs to be subjected to a related security verification process, and after verification is passed, a related communication path is opened after the vehicle-mounted terminal or the dashboard is updated.
It should be understood that when a batch of equipment update is performed, in order to save time, the update information and related content may be selectively issued through the internet of vehicles platform, so that before such an irregular update task starts, the vehicle needs to be connected to the internet of vehicles platform, and the manufacturer, official maintenance agency or partner maintenance agency will record the vehicle to be updated and the update content for such a large update task, and after the record is passed, when the vehicle is connected to the internet of vehicles, the vehicle terminal will receive and check the related prompt information.
Step S20: and after the safety verification is passed, receiving the whole vehicle configuration information table, and starting an engineering mode.
Before the vehicle goes down the production line, the flashing device on the production line is connected to the vehicle, original configuration information is stored at two places of the vehicle-mounted terminal and the dashboard, the vehicle configuration information is used as double backup, after the vehicle is powered on, the dashboard in the vehicle sends information of the configuration table outwards according to a plurality of packets of messages, and each ECU (gateway, ABS, BCM, MMI and the like) extracts the required configuration information and writes the required configuration information into the storage space of the ECU, and meanwhile, the configuration flashing mark position is the flashing.
It can be understood that each ECU related to configuration and writing is provided with a configuration and writing flag bit, and the states of the writing flag bits are three types respectively: swiped, un-swiped, protected. Before the writing or configuration acquisition is not performed, the flag bit is not written, when writing flag bits of the instrument and the vehicle-mounted terminal are not written, the instrument panel console can send prompt information, such as 'please write the whole vehicle configuration', when a user sees the prompt information, whether writing is authorized or not can be autonomously determined, on the other hand, the vehicle-mounted terminal can compare the configuration information sent by the instrument panel console, when certain configuration information is inconsistent, the vehicle-mounted terminal requests the instrument to prompt 'current configuration information is inconsistent and synchronous configuration information', and meanwhile, the vehicle-mounted terminal modifies according to the configuration information of the instrument.
It should be understood that a general-purpose flashing tool is built in the dashboard console, and in the case of the on-engineering mode, all types of ECU and configuration information of the in-vehicle terminal can be flashed through the built-in general-purpose flashing tool.
Step S30: and determining a target component to be subjected to the refreshing and corresponding refreshing content according to the whole vehicle configuration information table.
It should be noted that, the whole vehicle configuration information table refers to a brushing information table of the brushing task at this time, and is not a backup of the whole vehicle configuration information at this time, and according to a comparison result of the obtained whole vehicle configuration information table and the backup information, a target component to be brushed and related information of the component to be brushed can be obtained.
It can be understood that the target component to be refreshed determines the subsequent refreshing flow, when the target component to be refreshed is the ECU, the refreshing can be performed directly through the dashboard after the verification flow, when the object to be refreshed is the vehicle-mounted terminal, because the vehicle-mounted terminal stores the configuration backup information of the vehicle, the vehicle-mounted terminal performs the security verification again to the dashboard before the refreshing, and the next refreshing action can be performed only after the dashboard passes the security verification from the vehicle-mounted terminal.
Step S40: and based on a general brushing tool, brushing according to a preset brushing flow of the target component, and updating a brushing zone bit of the target component after the brushing is completed.
When the type of the target component includes both the vehicle-mounted terminal and the instrument panel, the configuration information of the instrument and the vehicle-mounted terminal can be updated only by brushing according to the brushing flow when the vehicle is off line, and when the pre-condition is not present, the user only needs to brush through the built-in brushing tool on the instrument panel.
It can be understood that, both the refreshing action of updating the configuration information of the original device and the refreshing action of rewriting the configuration information required by the new device after the device is replaced can be performed by the general refreshing tool built in the dashboard console on the premise of entering the engineering mode.
It should be appreciated that there are already some general-purpose brushware products on the market for replacing the original multiple ECU-specific brushware. These products are typically developed by specialized automotive electronics manufacturers or software development companies that, over time, develop and test, can communicate with, read data from, and write programs to the ECUs of a variety of vehicles. The universal type writing tool has the characteristic of multi-protocol support, CAN adapt to various communication protocols used by different vehicle manufacturers, such as CAN, K-line, J1850 and the like, and CAN also support ECU models of a plurality of vehicle manufacturers, including the support of the vehicle systems such as the solar system, the European system, the American system and the like, and the products have different brands and models in the market, wherein some of the more known and widely used brands comprise Autel, launch, bosch and the like, and the specific universal type writing tool in the scheme is not repeated herein.
In the present embodiment, security verification is performed on the current vehicle configuration information; when the safety verification is passed, receiving a whole vehicle configuration information table, and starting an engineering mode; determining a target component to be subjected to brushing and corresponding brushing content according to the whole vehicle configuration information table; and based on a general brushing tool, brushing according to a preset brushing flow of the target component, and updating a brushing zone bit of the target component after the brushing is completed. The safety verification flow ensures the safety of the refreshing operation, prevents unauthorized configuration modification or malicious behavior, and improves the safety of the refreshing operation and related steps and the refreshing efficiency by utilizing the built-in universal refreshing tool and the preset refreshing flow.
Referring to fig. 3, fig. 3 is a flowchart illustrating a second embodiment of the method for refreshing an automobile configuration according to the present invention.
Based on the first embodiment, the step S10 in the method for brushing the automobile configuration according to the present embodiment includes:
Step S101: and sending the encryption configuration backup information and the configuration verification instruction to each component in the vehicle based on the vehicle configuration backup information.
It can be understood that the whole vehicle configuration information table can be uploaded by related staff through the vehicle-mounted terminal, and can also be directly issued to the corresponding vehicle through the vehicle networking platform, and the difference is that the factory or the official serviceman directly managed by the factory generally has the vehicle networking management account of the factory, and can directly issue to the vehicle through the vehicle networking platform, but in most cases, the maintenance or configuration change of the vehicle can be performed in a cooperative maintenance unit, so that the uploading situation by the vehicle-mounted terminal is most, on the other hand, the configuration update of the vehicle needs the confirmation of the client, and only the configuration content approved and authorized by the client can be considered as the configuration content which can be written.
It should be understood that the internet of vehicles platform is only updated by large-scale vehicle software and hardware or only intervened under specific conditions, normal maintenance is performed by uploading and writing information through the vehicle-mounted terminal under the condition of obtaining user authorization, in addition, in the verification process, as the vehicle is provided with backup information of vehicle configuration, the backup information covers the configuration information of all components, which is equivalent to a complete record table, the storage unit in each component also records the configuration information in the component, which is equivalent to scattered records, and the verification process is to compare the total record table with the record content of each component, and if all the backup information is the same, the verification is considered to pass.
Step S102: and when the verification passing signals returned by all the components are received, the current vehicle configuration information is confirmed to pass the safety verification.
If the device replacement or maintenance is performed on the vehicle-mounted terminal and the instrument panel which retain all the information to be written, the relevant staff or the user himself needs to record the writing operation on the internet of vehicles before the writing operation starts due to the consideration of information security, and if the writing operation is not recorded or recorded but not authorized, the encryption mark of the security mark is considered to be failed in the security verification, and if the verification is passed, the entire vehicle configuration information table is subjected to the security marking.
It should be appreciated that the encryption algorithm herein is the same set of algorithms as the encryption algorithm of each ECU in the previous step, and each target component can identify and determine the encryption information to ensure the legitimacy of the content being written. On the other hand, after passing the validity verification, the vehicle networking platform transmits the marked whole vehicle configuration information table back to the vehicle-mounted terminal, and the whole vehicle configuration information table is forwarded to the instrument panel by the vehicle-mounted terminal to serve as the configuration backup information of the vehicle after the brushing action, and after that, the vehicle can be immediately brushed or refreshed again after waiting for the next power-on of the vehicle system, and the vehicle configuration information table can be realized through a built-in brushing tool.
In this embodiment, a security verification request is sent to the internet of vehicles platform through the vehicle-mounted terminal, the whole vehicle configuration information table to be refreshed is uploaded, and the configuration information is transmitted back to the dashboard after security verification and encryption marking. The method ensures the safety and legality of the writing and brushing actions through the steps of recording, verifying, encrypting and the like, effectively manages and controls the changing process of the vehicle configuration, improves the reliability and safety of the writing and brushing operation, effectively prevents unauthorized configuration change, and beneficially protects the integrity and stability of the vehicle data and the system.
Referring to fig. 4, fig. 4 is a flowchart of a third embodiment of the method for refreshing an automobile configuration according to the present invention.
Based on the first embodiment, the step S30 in the method for brushing the automobile configuration according to the present embodiment includes:
Step S301: and determining a configuration information changing part through the whole vehicle configuration information table and the written flag bits of all the parts of the vehicle.
It can be understood that the whole vehicle configuration information table to be refreshed records the configuration information of the whole vehicle, and private configuration information is additionally reserved in the storage space of the ECU of each ECU, the vehicle-mounted terminal and other components which are likely to be refreshed, the partial information can not be read and written, only comparison verification is performed, after the whole vehicle configuration information is compared with the private configuration information stored by each ECU, the comparison result can reflect the target component to be refreshed, and the refreshing content of the whole vehicle configuration information table is determined.
Step S302: and determining a target component needing to be written according to the configuration information changing part, wherein the type of the target component comprises a vehicle-mounted terminal, a dashboard and an ECU.
It should be noted that when the single flashing task does not include the vehicle-mounted terminal and the dashboard at the same time, the flashing can be performed according to the normal flashing flow when the vehicle enters the engineering mode, and when two components storing the vehicle configuration information are replaced or configured at the same time, the higher authority security authentication is required and the corresponding flow is executed.
Step S303: and determining the refreshing content of the target component according to the target component and the configuration information changing part.
Step S401: and when the target component types do not contain the vehicle-mounted terminal and the instrument panel at the same time, activating the writing permission of the instrument panel.
Further, the brushing zone bit of the vehicle-mounted terminal and the instrument panel is obtained, and the brushing zone bit in the vehicle-mounted terminal and the instrument panel is used as backup information reference equipment; and verifying the safety mark of the whole vehicle configuration information table recorded by the backup information reference equipment, and activating the refreshing authority of the instrument panel after the safety mark is verified to be free of errors.
Step S402: and writing the writing content into a corresponding target component through a general writing tool arranged in the instrument panel, and updating writing flag bits of the target component after writing is completed.
It can be understood that when the vehicle changes the vehicle-mounted terminal, the configuration writing flag bit is not written, and when the vehicle-mounted terminal confirms that the meter writing flag bit is written, the vehicle-mounted terminal requests the vehicle configuration information from the meter, after the meter confirms that the vehicle-mounted terminal is legal, the vehicle-mounted terminal sends the configuration information, and after the meter confirms that the meter is legal, the vehicle-mounted terminal writes the configuration information into the internal storage space. When the vehicle changes the meter, the meter configures the writing-brushing zone bit to be un-written, and when the meter confirms that the writing-brushing zone bit of the vehicle-mounted terminal is written, the meter requests the vehicle-mounted terminal to send the whole vehicle configuration information, and after the vehicle-mounted terminal confirms that the meter is legal, the vehicle-mounted terminal sends the configuration information and the encryption information to the meter, and after the meter confirms that the vehicle-mounted terminal is legal, the vehicle-mounted terminal writes the configuration information into the storage space. After the instrument writes the configuration information, the instrument is prompted to update the configuration of the instrument, the instrument is powered on again, after the vehicle is powered on again, the instrument sends out new configuration information, and each ECU checks and updates the configuration information of the instrument. When the vehicle changes other ECUs, the ECU reads the written flag bit of the ECU as un-written, the ECU requests an instrument prompt of 'xxx (ECU name) to be changed and to be electrified again', the instrument confirms that the self configuration written flag bit is read and then pops the window prompt, after the vehicle is electrified again, the ECU receives encryption information and configuration information sent by the instrument, and extracts the required configuration information to be written into an internal storage space after the legitimacy of the instrument is confirmed.
Optionally, when the target component type contains both a vehicle-mounted terminal and an instrument panel, closing the writing permission of the instrument panel; verifying the safety mark of the whole vehicle configuration information table, opening a standby refreshing interface after confirming that the safety mark is correct, and connecting external general refreshing equipment; and carrying out safety verification on the external general-purpose brushing equipment, and after the verification is passed, carrying out brushing on the target component through the external general-purpose brushing equipment, and updating the brushing zone bit of the target component after the brushing is completed.
It can be understood that when the target component type includes both the vehicle terminal and the dashboard, the flashing behavior of the dashboard cannot be considered as effective for the first security verification, and at this time, the flashing authority of the dashboard needs to be closed, and all components of the vehicle are flashed again according to the flashing flow when the vehicle leaves the factory, so as to ensure the security of the flashing behavior.
It should be noted that, the external general-purpose writing and brushing device is generally unique to a manufacturer, and has a special device identification number or identification method, when a vehicle identifies the device, the communication authority of the external writing and brushing communication port of the device is opened, the manufacturer can write and brush new device through the port, and after writing and brushing is completed, the writing and brushing flag bit is adaptively modified.
In this embodiment, the configuration information changing portion is determined by the entire vehicle configuration information table and the writing flag bits of each part of the vehicle, the target part to be written is determined, and the writing content is determined according to the target part and the configuration information changing portion. In the process of the brushing, the brushing authority of the instrument panel is respectively activated or external general brushing equipment is used according to different types of the target components, and the brushing zone bit of the target component is updated after the brushing is completed. Through strict verification and encryption processes, the safety and the legality of the refreshing behavior are ensured, and the change process of the vehicle configuration is effectively managed. Meanwhile, different brushing modes are adopted according to different types of target components, so that the flexibility and adaptability of brushing operation are improved, complex processes and manual intervention are reduced, the accuracy and consistency of vehicle configuration can be ensured, and the performance and stability of the whole vehicle system are improved.
