Technical Field

[0001] This application relates to the field of ECU flashing, and more specifically, to a control method, control device, computer-readable storage medium, processor, and ECU flashing system for an ECU data flashing device. Background Technology

[0002] When upgrading the software of ECU (Electronic Control Unit) on the market, diagnostic service tools are required. However, the current diagnostic service tools perform full-area flashing or data area flashing based on user instructions. If the user instructions are incorrect, the ECU that should have been flashed with a full area flashing may only have its data area flashed due to the incorrect user instructions, which will cause the ECU flashing to fail and result in a waste of human and material resources.

[0003] Therefore, there is an urgent need for a method to solve the problem of low reliability of the current write control method. Summary of the Invention

[0004] The main objective of this application is to provide a control method, control device, computer-readable storage medium, processor, and ECU flashing system for an ECU data flashing device, in order to solve the problem of poor reliability of the control method of the data flashing device in the prior art.

[0005] To achieve the above objectives, according to one aspect of this application, a control method for an ECU data flashing device is provided. The method includes: receiving data to be flashed, the data including predetermined version information; and controlling the data flashing device to flash the data to be flashed to a predetermined area of ​​a target ECU according to a flashing result and / or a user instruction. The predetermined area is either the entire ECU or a data area, the entire ECU including the data area and a program code area. The flashing result is determined based on the current version information in the target ECU and the predetermined version information. If the current version information matches the predetermined version information, the flashing result indicates that data flashing is performed on the data area; if the current version information does not match the predetermined version information, the flashing result indicates that data flashing is performed on the entire ECU. The user instruction is either a first instruction to flash the data area or a second instruction to flash the entire ECU.

[0006] Optionally, the data flashing device includes a display interface. Before controlling the data flashing device to flash the data to be flashed to a predetermined area of ​​the target ECU according to the flashing result and / or user instruction, the method further includes: controlling the display interface to display a selection identifier, the selection identifier including an identifier for selecting to generate the first instruction and an identifier for selecting to generate the second instruction; and generating the user instruction in response to a first predetermined operation acting on the selection identifier.

[0007] Optionally, based on the flashing result and / or user instructions, controlling the data flashing device to flash the data to be flashed to a predetermined area of ​​the target ECU includes: if the flashing result indicates that data flashing is performed on the entire area, controlling the data flashing device to flash the data to be flashed to the entire area; if the flashing result indicates that data flashing is performed on the data area, controlling the data flashing device to execute the user instructions to flash the data to be flashed to the predetermined area.

[0008] Optionally, based on the flashing result and / or user instructions, controlling the data flashing device to flash the data to be flashed to a predetermined area of ​​the target ECU includes: if the flashing result indicates that data flashing is performed on the data area, controlling the data flashing device to flash the data to be flashed to the data area; if the flashing result indicates that data flashing is performed on the entire area, controlling the data flashing device to flash the data to be flashed to the entire area.

[0009] Optionally, before controlling the data flashing device to flash the data to be flashed to a predetermined area in the target ECU according to the flashing result and / or user instructions, the method further includes: obtaining data flashing permission for the entire area, wherein the data flashing permission is the permission to modify the data in the entire area.

[0010] Optionally, the data flashing device includes a display interface. Before controlling the data flashing device to flash the data to be flashed to a predetermined area of ​​the target ECU according to the flashing result and / or user instructions, the method includes: upon receiving the data to be flashed, controlling the display interface to display a flashing start indicator; in response to a second predetermined operation acting on the flashing start indicator, determining the predetermined version information and the current version information according to the data to be flashed and the target ECU.

[0011] According to another aspect of this application, a control device for an ECU data flashing device is provided. The device includes a receiving unit and a control unit. The receiving unit receives data to be flashed, the data including predetermined version information. The control unit controls the data flashing device to flash the data to be flashed to a predetermined area of ​​a target ECU according to a flashing result and / or a user instruction. The predetermined area is either the entire area or a data area. The entire area includes the data area and a program code area. The flashing result is determined based on the current version information in the target ECU and the predetermined version information. If the current version information matches the predetermined version information, the flashing result indicates that data flashing is performed on the data area. If the current version information does not match the predetermined version information, the flashing result indicates that data flashing is performed on the entire area. The user instruction is either a first instruction to flash the data area or a second instruction to flash the entire area.

Wherein, if the current version information is consistent with the predetermined version information, the flashing result indicates that data is flashed to the data area; if the current version information is inconsistent with the predetermined version information, the flashing result indicates that data is flashed to the entire area. The user instruction is either a first instruction to flash the data area or a second instruction to flash the entire area. Compared to existing technologies where data flashing devices only execute ECU flashing operations based on user instructions, which can easily lead to flashing failures, this application adds confirmation of the flashing result. By using the current version information of the target ECU and the version information to be flashed, it determines which flashing method is suitable for the target ECU.

[0027] As described in the background section, the control methods of existing data writing devices have poor reliability. To solve the above problems, embodiments of this application provide a control method, control device, computer-readable storage medium, processor, and ECU writing system for an ECU data writing device.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] Example 1

[0030] According to an embodiment of the present invention, a control method embodiment for an ECU data flashing device is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0031] Figure 1 This is a flowchart of a control method for an ECU data flashing device according to an embodiment of this application. Figure 1 As shown, the method includes the following steps:

[0032] Step S101: Receive the data to be flashed, which includes the predefined version information;

[0033] In practical applications, the data to be written in this application is data sent by those skilled in the art through a data management platform, which is communicatively connected to the data writing device. Currently, the sending end of the data is not limited to the aforementioned data management platform, but can also be a terminal device connected to the data writing device, such as a computer, tablet, or mobile phone.

[0034] The data to be flashed is the new software data to be flashed into the ECU, and the predetermined version information is the version information of the new software data. The flashing device can be a diagnostic service tool or other devices that can be used to flash ECUs.

[0035] Step S102: Based on the flashing result and / or user instruction, control the data flashing device to flash the data to be flashed to a predetermined area of ​​the target ECU. The predetermined area is either the entire area or a data area. The entire area includes the data area and the program code area. The flashing result is determined based on the current version information and the predetermined version information in the target ECU. If the current version information and the predetermined version information are consistent, the flashing result indicates that the data area is flashed. If the current version information and the predetermined version information are inconsistent, the flashing result indicates that the entire area is flashed. The user instruction is either a first instruction to flash the data area or a second instruction to flash the entire area.

[0036] In the control method of the ECU data flashing device of this application, firstly, data to be flashed, including predetermined version information, is received; then, according to the flashing result and / or user instruction, the data flashing device is controlled to flash the data to be flashed to the entire area or data area of ​​the target ECU. Wherein, if the current version information is consistent with the predetermined version information, the flashing result indicates that the data area is flashed; if the current version information is inconsistent with the predetermined version information, the flashing result indicates that the entire area is flashed. The user instruction is either a first instruction to flash the data area or a second instruction to flash the entire area. Compared to existing technologies where data flashing devices only execute ECU flashing operations based on user instructions, which can easily lead to flashing failures, this application adds confirmation of the flashing result. By using the current version information of the target ECU and the version information to be flashed, it determines which flashing method is suitable for the target ECU. Then, based on the flashing result and / or user instructions, it controls the data flashing device to flash the target ECU, ensuring a more reliable flashing control process and solving the problem of poor flashing reliability caused by existing technologies that only execute ECU flashing based on user instructions.

[0037] If the current version information matches the predetermined version information, it means that the information in the program code area of ​​the target ECU matches the program code information in the data to be flashed, and only the information in the data area is inconsistent with the data to be flashed. In this case, it is not necessary to erase and flash the information in the program code area; only the data area needs to be flashed. However, if the current version information does not match the predetermined version information, it means that both the information in the program code area and the information in the data area of ​​the target ECU are inconsistent with the corresponding information in the data to be flashed. In this case, a full flash of the target ECU is required to ensure successful flashing.

[0038] In addition, in the target ECU, the flashing time for the data area only accounts for 20% of the total flashing time for the entire area. If only the data area is flashed, the flashing time can be greatly reduced.

[0039] To further avoid the problem of wasted manpower and resources due to target ECU flashing failure, such as... Figure 2 As shown, based on the flashing result and / or user instructions, the data flashing device is controlled to flash the data to be flashed to a predetermined area of ​​the target ECU. Specifically, step S102 includes the following implementation process:

[0040] Step S1021: When the above-mentioned writing result indicates that the above-mentioned whole area is being written with data, control the above-mentioned data writing device to write the above-mentioned data to be written to the above-mentioned whole area.

[0041] Step S1022: If the above-mentioned writing result indicates that data has been written to the above-mentioned data area, control the above-mentioned data writing device to execute the above-mentioned user instruction to write the above-mentioned data to be written to the above-mentioned predetermined area.

[0042] In the above embodiments, the data flashing device is controlled to flash the target ECU based on both the flashing result and the user command, further ensuring the reliability of the flashing process. Specifically, when a flashing result indicating a full-area data flash is obtained, it means that only a full-area flash is applicable to the current data to be flashed. In this case, regardless of the user command, the data flashing device will be directly controlled to flash the data to be flashed to the entire area. This ensures that even if the user command is transmitted incorrectly (i.e., the user command is the first command), the flashing of the target ECU will not fail, avoiding the waste of manpower, resources, and time caused by flashing failure. When a flashing result indicating a data area flash is obtained, it means that either a full-area flash or a data area flash can be used for the current data to be flashed. In this case, the data flashing device is controlled to flash the data to be flashed to the predetermined area based on the user command. This gives the flashing control personnel a great deal of freedom, allowing them to choose whether to perform a full-area flash, avoiding the problem of being unable to flash the entire area when the goal is to do so, and ensuring a better user experience.

[0043] Of course, the specific implementation of step S102 is not limited to the above-described method. In other embodiments of this application, in order to further avoid data writing device failure and further shorten the writing time of the target ECU, according to a specific embodiment of this application, the data writing device is controlled to write the data to be written to a predetermined area of ​​the target ECU according to the writing result and / or user instruction. This includes: when the writing result indicates that the data area is being written, the data writing device is controlled to write the data to be written to the data area; when the writing result indicates that the entire area is being written, the data writing device is controlled to write the data to be written to the entire area.

[0044] In the above embodiments, the data flashing device is controlled to flash the data to be flashed to a predetermined area of ​​the target ECU only based on the flashing result. When it is determined that only the data area of ​​the target ECU is to be flashed, the program code area in the target ECU does not need to be erased and rewritten. This can save about 80% of the flashing time compared to flashing the entire area, further saving flashing time. Furthermore, when it is determined that the entire area is to be flashed, the entire area is flashed, further avoiding the problem of flashing failure of the target ECU due to incorrect user commands, further ensuring the successful flashing of the target ECU.

[0045] To facilitate subsequent flashing operations on the target ECU, in another embodiment of this application, before controlling the data flashing device to flash the data to be flashed to a predetermined area in the target ECU according to the flashing result and / or user instructions, the method further includes: obtaining data flashing permission for the entire area, wherein the data flashing permission is the permission to modify the data in the entire area.

[0046] More specifically, according to a specific embodiment of this application, such as Figure 3 As shown, the aforementioned data flashing device includes a display interface. Before controlling the data flashing device to flash the data to be flashed to a predetermined area of ​​the target ECU according to the flashing result and / or user instructions, the method further includes:

[0047] Step S201: Control the display interface to display selection indicators, including an indicator for selecting to generate the first instruction and an indicator for selecting to generate the second instruction.

[0048] Step S202: In response to the first predetermined operation acting on the selection identifier, the user instruction is generated.

[0049] This application displays selection icons through a display interface, allowing flashing personnel to select the corresponding icons according to the actual situation, thereby generating flashing instructions that conform to the actual situation. This further enables flashing personnel to control the flashing process more conveniently and further ensures the control freedom of flashing personnel.

[0050] The first predetermined operation mentioned above can be an operation such as clicking, checking, or dragging on the display interface. Those skilled in the art can set it flexibly.

[0051] To further ensure convenient control of the flashing process by the flashing personnel, according to another specific embodiment of this application, such as... Figure 4 As shown, the data flashing device described in this application includes a display interface. Before controlling the data flashing device to flash the data to be flashed to a predetermined area of ​​the target ECU according to the flashing result and / or user instructions, the method includes:

[0052] Step S301: Upon receiving the data to be written, control the display interface to display the write start indicator;

[0053] In step S302, in response to the second predetermined operation acting on the flashing start identifier, the predetermined version information and the current version information are determined based on the data to be flashed and the target ECU.

[0054] In the above process, the flashing process only begins after receiving the second pre-defined operation from the flashing personnel, which further facilitates the flashing personnel in controlling the start of the flashing process at any time.

[0055] The second predetermined operation described above can be an operation such as clicking, checking, or dragging on the display interface. Those skilled in the art can set it flexibly.

[0056] After obtaining data flashing permission for the entire region, this application receives the data to be flashed from the data management platform and displays a flashing start indicator on the display interface. Based on the data to be flashed and the target ECU, the application determines the predetermined version information and the current version information, which facilitates the subsequent determination of the flashing result by verifying the predetermined version information and the current version information, and further ensures the reliability of the flashing.

[0057] In a specific embodiment, the control process of the ECU data flashing device described in this application is as follows: Figure 5 As shown, firstly, full-area data flashing permission is obtained. Secondly, the flashing personnel use the authorized data to click the start flashing icon on the display interface to begin reading the current version information of the target ECU and verifying it against the predetermined version information. If the current version information matches the predetermined version information, the data flashing device is controlled to flash the data of the target ECU according to the user's instructions. If the user's instructions are the first instructions, the data area of ​​the target ECU is flashed. If the user's instructions are the second instructions, the entire area of ​​the target ECU is flashed. If the current version information does not match the predetermined version information, the entire area is flashed directly.

The predetermined area is either the entire area or a data area. The entire area includes the data area and the program code area. The flashing result is determined based on the current version information and the predetermined version information in the target ECU. When the current version information is consistent with the predetermined version information, the flashing result indicates that the data area is flashed. When the current version information is inconsistent with the predetermined version information, the flashing result indicates that the entire area is flashed. The user instruction is either a first instruction to flash the data area or a second instruction to flash the entire area.

[0061] In the control device of the ECU data flashing device of this application, a receiving unit receives data to be flashed, including predetermined version information, and a first control unit controls the data flashing device to flash the data to be flashed to the entire area or data area of ​​the target ECU according to the flashing result and / or user instruction. Wherein, if the current version information is consistent with the predetermined version information, the flashing result indicates that the data area is flashed; if the current version information is inconsistent with the predetermined version information, the flashing result indicates that the entire area is flashed. The user instruction is either a first instruction to flash the data area or a second instruction to flash the entire area. Compared to existing technologies where data flashing devices only execute ECU flashing operations based on user instructions, which can easily lead to flashing failures, this application adds confirmation of the flashing result.
