[0048] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0049] In the following description, suffixes such as "module", "component", or "unit" used to represent elements are only for facilitating the description of the present invention and have no specific meaning in themselves. Therefore, "module", "component", or "unit" can be used interchangeably.

[0050] Figure 1 is the first flowchart of the method for upgrading the digital key version of the present invention. In this embodiment, a method for upgrading the digital key version is proposed, which is applied to a network access device in a vehicle networking terminal. The method includes:

[0051] S1. Download and store the software package corresponding to the controller;

[0052] S2. Analyze and identify the software package, where

[0053] S3. If the software package only includes the software corresponding to the old hardware of the controller, execute a preset first software flashing scheme for the controller;

[0054] S3`. If the software package includes the software corresponding to the old hardware and the software corresponding to the new hardware of the controller, determine to execute the first software flashing scheme or a preset second software flashing scheme for the controller according to the hardware version of the controller.

[0055] In this embodiment, a TBOX (Telematics Box, vehicle networking terminal) is used as the gateway entry for the digital key-related controller, and provides routing and processing of relevant diagnostic signals. Specifically, the vehicle networking terminal serves as the gateway entry for the digital key-related controller. When the vehicle needs to update the digital key-related controller, software download and flashing work are uniformly carried out through the vehicle networking terminal. Among them, first, the software of the controller that needs to be flashed is downloaded to the NAD (Network Access Device) module of the vehicle networking terminal through the upper computer or / and the background; then, the software package is analyzed and identified. If the software package only includes the software corresponding to the old hardware of the controller, execute a preset first software flashing scheme for the controller; if the software package includes the software corresponding to the old hardware and the software corresponding to the new hardware of the controller, determine to execute the first software flashing scheme or a preset second software flashing scheme for the controller according to the hardware version of the controller.

[0056] Please refer to Figure 9 , specifically, in this embodiment, before performing the flashing, first perform the judgment of the new and old software packages and the judgment of the new and old hardware, and then perform the flashing of the intelligent digital key-related controller according to the target process, mainly including:

[0057] Step 1, Hardware version judgment: The intelligent digital key-related controller notifies the vehicle networking terminal whether it is old hardware or new hardware through fixed CAN messages. For example, in a certain CAN ID definition, 0x01 represents the old hardware of manufacturer A, 0x02 represents the new hardware of manufacturer A, 0x03 represents the old hardware of manufacturer B, and 0x04 represents the new hardware of manufacturer B;

[0058] Step 2, Software download: Download the software of the controller ECU1 that needs to be flashed to the NAD module in the vehicle networking terminal for storage through the upper computer or / and the background;

[0059] Step 3, Software package judgment: NAD judges whether the software package downloaded and stored in Step 2 contains only the software package for old hardware or both the software packages for old hardware and new hardware. For example, it is judged by the number of HEX (hexadecimal) packages or the size;

[0060] Step 4, NAD module flashing scheme judgment: When the NAD module judges in Step 3 that the target software package contains only the software for old hardware, it directly executes the flashing according to the old scheme. However, when the NAD module judges in Step 3 that the target software package contains the software for both old hardware and new hardware, the NAD needs to execute the flashing of the old scheme or the new scheme according to the actual vehicle hardware version status in Step 1;

[0061] Step 5, The NAD module sends the instruction to upgrade ECU1 to the microprocessor MCU of the vehicle networking terminal, and the MCU feeds back the upgrade request to the target ECU1 controller through CAN FD messages;

[0062] Step 6, After the target ECU1 controller responds and feedbacks, the NAD module starts to unpack and send the software sub-packages to the MCU;

[0063] Step 7, The MCU and the target ECU1 perform multi-pack CAN FD message interaction data transmission;

[0064] Step 8, After the upgrade transmission is completed, the target ECU feeds back the upgrade result to the MCU, and the MCU forwards it to the NA module to report the upgrade result;

[0065] Subsequently, the above steps can be repeated for the upgrade method of the same ECU; for ECU2, it is as follows:

[0066] Step 9, Software download: Download the software of the controller ECU2 that needs to be flashed to the NAD module in the vehicle networking terminal for storage through the upper computer or / and the background;

[0067] Step 10: The NAD module sends the instruction to upgrade ECU2 to the microprocessor MCU of the vehicle networking terminal, and the MCU feeds back the upgrade request to the target ECU2 controller through a CAN FD message;

[0068] Step 11: After the target ECU2 controller responds, the NAD module starts to unpack and send the software sub-package to the MCU;

[0069] Step 12: The MCU and the target ECU2 perform multi-packet CAN FD message interactive data transmission;

[0070] Step 13: After the upgrade transmission is completed, the target ECU feeds back the upgrade result to the MCU, and the MCU transparently transmits it to the NA module to report the upgrade result;

[0071] Subsequently, the above steps can be repeated for the upgrade methods of other ECUs.

[0072] The beneficial effect of this embodiment is that by downloading and storing the software package corresponding to the controller; parsing and identifying the software package, wherein, if the software package only includes the software corresponding to the old hardware of the controller, then execute a preset first software flashing scheme for the controller; if the software package includes the software corresponding to the old hardware and the software corresponding to the new hardware of the controller, then determine to execute the first software flashing scheme or a preset second software flashing scheme for the controller according to the hardware version of the controller. A digital key version upgrade scheme with higher compatibility is realized, effectively simplifying the upgrade steps, reducing the environmental dependence, improving the upgrade versatility, and saving manpower, material resources and development costs.

[0073] Figure 2 This is the second flowchart of the digital key version upgrade method of the present invention. Based on the above embodiment, the downloading and storing the software package corresponding to the controller specifically includes:

[0074] S11: Establish a communication link with the host computer or the background server;

[0075] S12: Download the software package through the communication link, wherein the software package includes software of at least one hardware type.

[0076] In this embodiment, considering that there are two different pieces of hardware from the same supplier on a vehicle model, correspondingly, there will be two HEX software that need to be flashed. Before the upgrade in this embodiment, when downloading software, the upgrade software corresponding to the new hardware and the upgrade software corresponding to the old hardware are downloaded together. However, specifically, whether it is the upgrade software corresponding to the new hardware or the upgrade software corresponding to the old hardware is identified according to the CAN messages periodically broadcast by the intelligent digital key (UWB&WPC&NFC&other ECUs) controller. For example, in CAN ID = 0x300, 0 in the first byte represents the old hardware of supplier A, 1 represents the new hardware of supplier A, 2 represents the old hardware of supplier B, 3 represents the new hardware of supplier B, and so on.

[0077] The beneficial effect of this embodiment is that by downloading the software package as a whole, the complexity of the preparatory work before the upgrade is greatly reduced. And through subsequent periodic broadcasts for differential upgrade division, targeted upgrades for new and old hardware can be effectively carried out, improving the compatibility of the software package.

[0078] Figure 3 It is the third flowchart of the digital key version upgrade method of the present invention. Based on the above embodiment, parsing and identifying the software package specifically includes:

[0079] S21. Identify the software type in the software package;

[0080] S22. Determine the number of software packages and / or the size of the software package of the software package as the current software judgment condition according to the software type.

[0081] In this embodiment, considering that there are two different pieces of hardware from the same supplier on a vehicle model, correspondingly, there will be two HEX software that need to be flashed. Further, in this embodiment, the number of software packages and / or the size of the software package of the software package are determined as the current software judgment condition according to the software type, and this software judgment condition is used to determine the flashing type corresponding to the above uniformly downloaded software package.

[0082] The beneficial effect of this embodiment is that by identifying the software type in the software package and determining the number of software packages and / or the size of the software package of the software package as the current software judgment condition according to the software type, the above uniformly downloaded software package can be effectively identified and divided, avoiding the situation of confusion in flashing new and old hardware.

[0083] Figure 4 It is the fourth flowchart of the digital key version upgrade method of the present invention. Based on the above embodiment, parsing and identifying the software package further includes:

[0084] S23. Detect the software package according to the software judgment condition;

[0085] S24. Determine whether the software package only includes the software corresponding to the old hardware or includes the software corresponding to both the old hardware and the new hardware according to the detection result.

[0086] In this embodiment, if it is determined according to the detection result that the software package only includes the software corresponding to the old hardware, then the old solution is flashed, that is, the first software flashing solution. If it is determined that the software package includes the software corresponding to both the old hardware and the new hardware, then it is necessary to first judge whether to flash the new and old solutions, that is, to determine whether to adopt the first or second software flashing solution.

[0087] Specifically, the new solution or the old solution refers to the software update solution for the new hardware or the old hardware. For example, there are 2 HEX file packages to be flashed for the new hardware software, and 3 HEX file packages to be flashed for the old hardware software; further, the starting address of the flashed software is the same, but the number of HEX software packages to be flashed for the new hardware is less, which can also be understood as the number of software code lines is less.

[0088] The beneficial effect of this embodiment is that by detecting the software package and then determining whether the software package only includes the software corresponding to the old hardware or includes the software corresponding to both the old hardware and the new hardware according to the detection result, the first or second software flashing solution is made to conform to the actual package status of the software package, without the need to distinguish in the software package download stage, which is suitable for the application scenario of batch operation.

[0089] Figure 5 It is the fifth flowchart of the digital key version upgrade method of the present invention. Based on the above embodiment, taking the number of software packages as the current software judgment condition, the step of determining whether the software package only includes the software corresponding to the old hardware or includes the software corresponding to both the old hardware and the new hardware according to the detection result specifically includes:

[0090] S25. Judge whether the number of software packages exceeds a preset first threshold;

[0091] S26. If the number of software packages exceeds the first threshold, it is determined that the software package includes the software corresponding to both the old hardware and the new hardware; otherwise, it is determined that the software package only includes the software corresponding to the old hardware.

[0092] In this embodiment, the above threshold is determined according to the current hardware type, or according to the version of the current controller.

[0093] The beneficial effect of this embodiment is that by determining whether the number of software packages exceeds a preset first threshold, if the number of software packages exceeds the first threshold, it is determined that the software packages include software corresponding to both the old hardware and the new hardware, otherwise, it is determined that the software packages only include software corresponding to the old hardware, thereby realizing the identification of different software packages and subsequent upgrade matching, and reducing the workload of manual identification or individual operations.

[0094] Figure 6 It is the sixth flowchart of the digital key version upgrade method of the present invention. Based on the above embodiment, taking the software package size as the current software judgment condition, and determining whether the software packages only include software corresponding to the old hardware or include software corresponding to both the old hardware and the new hardware according to the detection result, specifically including:

[0095] S27. Determine whether the software package size exceeds a preset second threshold;

[0096] S28. If the software package size exceeds the second threshold, it is determined that the software packages include software corresponding to both the old hardware and the new hardware, otherwise, it is determined that the software packages only include software corresponding to the old hardware.

[0097] In this embodiment, the above threshold is determined according to the current hardware type, or according to the version of the current controller.

[0098] The beneficial effect of this embodiment is that by determining whether the software package size exceeds a preset second threshold, if the software package size exceeds the second threshold, it is determined that the software packages include software corresponding to both the old hardware and the new hardware, otherwise, it is determined that the software packages only include software corresponding to the old hardware, thereby realizing the identification of different software packages and subsequent upgrade matching, and reducing the workload of manual identification or individual operations.

[0099] Figure 7 It is the seventh flowchart of the digital key version upgrade method of the present invention. Based on the above embodiment, if the software packages only include software corresponding to the old hardware of the controller, a preset first software flashing scheme is executed on the controller, specifically including:

[0100] S31. Set the first software flashing scheme as flashing the old hardware;

[0101] S32. Use the software packages as the flashing packages for upgrading the controller, and after the controller gives a positive response feedback, execute the upgrade process on the controller.

[0102] In this embodiment, considering that there are two different pieces of hardware from the same supplier on a vehicle model, correspondingly, there will be two HEX software that need to be flashed. Before the upgrade in this embodiment, when downloading the software, the upgrade software corresponding to the new hardware and the upgrade software corresponding to the old hardware are downloaded together. However, specifically, whether it is the upgrade software corresponding to the new hardware or the upgrade software corresponding to the old hardware to be upgraded is identified based on the CAN messages periodically broadcast by the intelligent digital key (UWB&WPC&NFC&other ECUs) controller. For example, in CAN ID = 0x300, 0 in the first byte represents the old hardware of supplier A, 1 represents the new hardware of supplier A, 2 represents the old hardware of supplier B, 3 represents the new hardware of supplier B, and so on. Based on this, this embodiment sets the first software flashing scheme to flash the old hardware, uses the software package as the flashing package for upgrading the controller, and after the controller gives a positive response feedback, executes the upgrade process for the controller.

[0103] The beneficial effect of this embodiment is that by setting the first software flashing scheme to flash the old hardware, using the software package as the flashing package for upgrading the controller, and after the controller gives a positive response feedback, executing the upgrade process for the controller, a differentiated and adaptive flashing strategy for controllers with different hardware versions is achieved, greatly improving the flashing efficiency.

[0104] Figure 8 It is the eighth flowchart of the digital key version upgrade method of the present invention. Based on the above embodiment, if the software package includes the software corresponding to the old hardware and the software corresponding to the new hardware of the controller, then according to the hardware version of the controller, determine to execute the first software flashing scheme or the preset second software flashing scheme for the controller, which specifically includes:

[0105] S33. Set the flashing corresponding to the hardware version. Among them, if it is to flash the old hardware, use the software package as the flashing package for upgrading the controller; if it is to flash the new hardware, use at least a part of the software package as the flashing package for upgrading the controller;

[0106] S34. Use the software package as the flashing package for upgrading the controller, and after the controller gives a positive response feedback, execute the upgrade process for the controller.

[0107] In this embodiment, considering that there are two different types of hardware from the same supplier on a vehicle of a certain model, accordingly, there will be two HEX software to be flashed. Before the upgrade in this embodiment, when downloading the software, the upgrade software corresponding to the new hardware and the upgrade software corresponding to the old hardware are downloaded together. However, specifically, whether it is the upgrade software corresponding to the new hardware or the upgrade software corresponding to the old hardware to be upgraded is identified according to the CAN message periodically broadcast by the intelligent digital key (UWB&WPC&NFC&other ECUs) controller. For example, in CAN ID = 0x300, 0 in the first byte represents the old hardware of supplier A, 1 represents the new hardware of supplier A, 2 represents the old hardware of supplier B, 3 represents the new hardware of supplier B, and so on. Based on this, this embodiment sets the flashing corresponding to the hardware version. Among them, if it is the flashing of the old hardware, the software package is used as the flashing package for upgrading the controller. If it is the flashing of the new hardware, at least a part of the software package is used as the flashing package for upgrading the controller; the software package is used as the flashing package for upgrading the controller, and after the controller gives a positive response feedback, the upgrade process is executed for the controller.

[0108] The beneficial effect of this embodiment is that by setting the flashing corresponding to the hardware version, among which, if it is the flashing of the old hardware, the software package is used as the flashing package for upgrading the controller. If it is the flashing of the new hardware, at least a part of the software package is used as the flashing package for upgrading the controller. The software package is used as the flashing package for upgrading the controller, and after the controller gives a positive response feedback, the upgrade process is executed for the controller, thus realizing a differential and adaptive flashing strategy for controllers of different hardware versions, and greatly improving the flashing efficiency.
