[0038] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions of the present application are further elaborated in detail below in conjunction with the drawings and embodiments. The described embodiments should not be regarded as limiting the present application. All other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0039] In the following description, reference is made to "some embodiments", which describe a subset of all possible embodiments, but it is understood that "some embodiments" may be the same subset or different subsets of all possible embodiments, and may be combined with each other without conflict. The terms "first / second / third" involved are merely used to distinguish similar objects and do not represent a specific order for the objects. It is understood that "first / second / third" may be interchanged in a specific order or sequence where permitted, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing this application and are not intended to limit this application.

[0041] At present, when the infotainment system and / or instrument system of a vehicle's on-board equipment has an unrecoverable software failure such as a black screen, the system cannot be turned on, or the system firmware upgrade fails, since the infotainment system and / or instrument system of the on-board equipment is installed inside the vehicle, repairing the system failure generally requires going to a 4S shop or factory to dismantle the vehicle and remove the infotainment system and / or instrument system to perform a software upgrade and recovery on the infotainment system and / or instrument system of the on-board equipment.

[0042] However, the method of dismantling the car for upgrading consumes manpower and time. Car owners also have complaints about the method of dismantling the car, and this method is not conducive to after-sales maintenance.

[0043] In order to simplify the software upgrade method in the vehicle-mounted device, the embodiment of the present application provides an upgrade system. Figure 1 A schematic diagram of an optional upgrade system provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the upgrade system 100 may include: an in-vehicle device 11 and a terminal device 12; wherein,

[0044] The vehicle-mounted device 11 is a device including an infotainment system and / or an instrument system. The vehicle-mounted device 11 is provided with an on-board diagnostic system (OBD) interface and a USB interface for connecting to external devices. The terminal device 12 can establish a connection with the vehicle-mounted device 11 through the OBD interface to achieve communication.

[0045] The terminal device 12 is installed with a diagnostic tool for diagnosing the communication capability of the vehicle-mounted device 11. The terminal device 12 may be a personal computer, a tablet computer or a smart phone, and this embodiment of the present application does not specifically limit this.

[0046] Based on the above Figure 1 The upgrade system provided, the embodiment of the present application provides an upgrade method, Figure 2 A schematic diagram of an optional upgrade method provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, the upgrade method may include:

[0047] S201: The terminal device sends a detection message to the vehicle-mounted device through the OBD interface of the vehicle-mounted device;

[0048] In order to simplify the software upgrade method of the vehicle-mounted device, in an embodiment of the present application, when an irrecoverable software failure such as a black screen, the system cannot be turned on, or the system firmware upgrade fails occurs in the software system of the vehicle-mounted device, the terminal device is connected through the OBD interface of the vehicle-mounted device to establish a communication connection between the vehicle-mounted device and the terminal device.

[0049] Diagnostic tool software is installed on the terminal device, so that the terminal device can send a detection message to the vehicle-mounted device through the OBD interface of the vehicle-mounted device. The detection message can be a message using the Controller Area Network (CAN) protocol, wherein the detection message is used by the vehicle-mounted device to detect the communication capability of the vehicle-mounted device to generate a response message.

[0050] S202: After receiving the detection message, the vehicle-mounted device detects the communication capability of the vehicle-mounted device;

[0051] In S202, the vehicle-mounted device receives a detection message from the terminal device, triggering detection of the communication capability of the vehicle-mounted device.

[0052] The communication capability may include whether a microcontroller unit (MCU) of the vehicle-mounted device and a microprocessor unit (MPU) of the vehicle-mounted device have communication capability, and may also include whether a wireless network module of the vehicle-mounted device has communication capability.

[0053] S203: The vehicle-mounted device generates a response message according to the communication capability of the vehicle-mounted device, and sends it to the terminal device;

[0054] Through the above S202, the vehicle-mounted device detects its own communication capability, thereby knowing its own communication capability. In S203, the vehicle-mounted device generates a response message according to the communication capability of the vehicle-mounted device. In this way, the response message can indicate whether the MCU of the vehicle-mounted device and the MPU of the vehicle-mounted device have communication capabilities and whether the wireless network module of the vehicle-mounted device has communication capabilities.

[0055] The vehicle-mounted device sends the generated response message to the terminal device, so that the terminal device knows whether the MCU of the vehicle-mounted device has the communication capability with the MPU of the vehicle-mounted device and whether the wireless network module of the vehicle-mounted device has the communication capability.

[0056] S204: The terminal device determines an upgrade method of the vehicle-mounted device according to the response message;

[0057] The response message is generated through the above S203. In S204, after receiving the response message, the terminal device determines the upgrade method of the vehicle-mounted device according to the response message.

[0058] That is to say, the terminal device knows through the response message whether the MCU of the vehicle-mounted device and the MPU of the vehicle-mounted device have communication capabilities and whether the wireless network module of the vehicle-mounted device has communication capabilities, so as to determine the upgrade method that matches the communication capabilities of the vehicle-mounted device.

[0059] Among them, the above-mentioned upgrade methods may include: an upgrade method using Over The Air (OTA) technology, an upgrade method using a USB flash drive, and an upgrade method using a USB forced flash line.

[0060] S205: The terminal device generates an upgrade message according to the upgrade method and sends it to the vehicle-mounted device;

[0061] S206: After receiving the upgrade message, the vehicle-mounted device upgrades the vehicle-mounted device.

[0062] In S205, after determining the upgrade method, the terminal device generates an upgrade message according to the upgrade method, and then sends the upgrade message to the vehicle-mounted device. In S206, after receiving the upgrade message, the vehicle-mounted device upgrades the software on the vehicle-mounted device.

[0063] Here, the way in which the vehicle-mounted device obtains the upgrade package is different for different upgrade methods, and the terminal device cooperates differently for different upgrade methods.

[0064] In this way, through the exchange of messages between the terminal device and the vehicle-mounted device through the OBD interface, the terminal device can know the communication capability of the vehicle-mounted device, thereby determining an upgrade method suitable for the communication capability for the vehicle-mounted device, and then realizing the upgrade of the vehicle-mounted device software without disassembling the device, thereby simplifying the software upgrade method of the vehicle-mounted device.

[0065] After detecting the communication capability of the vehicle-mounted device, in order to generate a response message according to the communication capability of the vehicle-mounted device, in an optional embodiment, S203 may include:

[0066] When the communication capability of the vehicle-mounted device indicates that the MCU of the vehicle-mounted device and the MPU of the vehicle-mounted device have communication capability, the vehicle-mounted device generates a response message according to the communication capability of the wireless network module of the vehicle-mounted device in the communication capability of the vehicle-mounted device;

[0067] When the communication capability of the vehicle-mounted device indicates that the MCU and the MPU do not have the communication capability, the vehicle-mounted device generates a response message for indicating that the MCU and the MPU do not have the communication capability.

[0068] It can be understood that after obtaining the communication capability of the vehicle-mounted device, when the communication capability of the vehicle-mounted device indicates that the MCU and the MPU have communication capability, that is, the MCU and the MPU of the vehicle-mounted device can communicate normally, it is necessary to further check the communication capability of the wireless network module of the vehicle-mounted device in the communication capability of the vehicle-mounted device, and then generate a response message according to the communication capability of the wireless network module of the vehicle-mounted device.

[0069] In addition, when the communication capability of the vehicle-mounted device indicates that the MCU and the MPU do not have the communication capability, that is, the MCU and the MPU of the vehicle-mounted device cannot communicate normally, the generated response message is used to indicate that the MCU and the MPU do not have the communication capability.

[0070] In this way, a response message is generated based on whether the MCU and MPU have communication capabilities, or a response message is generated based on whether the wireless network module of the vehicle-mounted equipment has communication capabilities, so that the response message can be used to indicate whether the MCU and MPU have communication capabilities or whether the wireless network module has communication capabilities, thereby providing data for determining the upgrade method.

[0071] In order to realize the generation of a response message according to the communication capability of the wireless network module of the vehicle-mounted device, in an optional embodiment, when the communication capability of the vehicle-mounted device indicates that the MCU and the MPU have the communication capability, the vehicle-mounted device generates a response message according to the communication capability of the wireless network module of the vehicle-mounted device in the communication capability of the vehicle-mounted device, which may include:

[0072] When the communication capability of the vehicle-mounted device indicates that the MCU and the MPU have the communication capability, and the wireless network module has the communication capability with the external device, the vehicle-mounted device generates a response message for indicating that the wireless network module has the communication capability with the external device;

[0073] When the communication capability of the vehicle-mounted device indicates that the MCU and the MPU have the communication capability and the wireless network module does not have the communication capability with the external device, the vehicle-mounted device generates a response message indicating that the wireless network module does not have the communication capability with the external device.

[0074] It can be understood that after further checking, the wireless network module of the vehicle-mounted device has the ability to communicate with external devices, that is, the vehicle-mounted device can communicate with external devices through its own wireless network module, so at this time, the response message generated by the vehicle-mounted device indicates that the wireless network module has the ability to communicate with external devices. In addition, the wireless network module of the vehicle-mounted device does not have the ability to communicate with external devices, that is, the vehicle-mounted device cannot communicate with external devices through its own wireless network module, so at this time, the response message generated by the vehicle-mounted device indicates that the wireless network module does not have the ability to communicate with external devices.

[0075] In this way, a response message is further generated according to whether the wireless network module of the vehicle-mounted device has the communication capability, so that the response message can be used to indicate whether the wireless network module has the communication capability, thereby providing data for determining the upgrade method.

[0076] After receiving the response message, in order to determine the upgrade mode, in an optional embodiment, S204 may include:

[0077] The terminal device determines the upgrade mode of the vehicle-mounted device according to the communication capability of the vehicle-mounted device indicated in the response message.

[0078] It can be understood that after receiving the response message, the terminal device determines the upgrade method of the vehicle-mounted equipment according to the content indicated by the response message. Here, it should be noted that the upgrade method that can be selected is different due to the different communication capabilities of the vehicle-mounted equipment, so it is necessary to determine the upgrade method of the vehicle-mounted equipment based on the communication capabilities of the vehicle-mounted equipment.

[0079] In this way, after receiving the response message, the terminal device can determine the upgrade method of the vehicle-mounted device according to the content indicated by the response message, thereby determining an upgrade method suitable for the vehicle-mounted device's own communication capabilities, so that the vehicle-mounted device can complete the software upgrade.

[0080] Furthermore, in order to determine the upgrade mode of the vehicle-mounted device, in an optional embodiment, the terminal device determines the upgrade mode of the vehicle-mounted device according to the communication capability of the vehicle-mounted device indicated in the response message, which may include:

[0081] When the response message indicates that the MCU of the vehicle-mounted device and the MPU of the vehicle-mounted device do not have the communication capability, the terminal device determines that the upgrade mode of the vehicle-mounted device is the USB forced line flash upgrade mode.

[0082] It can be understood that when the response message indicates that the MCU and MPU do not have the ability to communicate, it means that the MCU and MPU cannot communicate with each other, so the vehicle-mounted device cannot choose the OTA upgrade method and the USB flash drive upgrade method. Therefore, the terminal device determines that the upgrade method of the vehicle-mounted device is the USB forced line flash upgrade method.

[0083] In this way, when the MCU and MPU cannot communicate, the terminal device determines that the upgrade method of the vehicle-mounted device is USB forced wire flash, so that the vehicle-mounted device can be upgraded using USB forced wire flash when the MCU and MPU cannot communicate, thereby realizing the smooth upgrade of the vehicle-mounted device.

[0084] In addition, in order to determine the upgrade mode of the vehicle-mounted device, in an optional embodiment, the terminal device determines the upgrade mode of the vehicle-mounted device according to the response message, which may include:

[0085] When the response message indicates that the MCU of the vehicle-mounted device has the communication capability with the MPU of the vehicle-mounted device, the terminal device determines the optional upgrade mode of the vehicle-mounted device according to the communication capability of the wireless network module of the vehicle-mounted device;

[0086] The terminal device determines an upgrade mode of the in-vehicle device from the optional upgrade modes in response to an operation on the optional upgrade modes of the in-vehicle device.

[0087] It can be understood that when the response message indicates that the MCU and MPU have the ability to communicate, the terminal device needs to further determine the optional upgrade method of the vehicle-mounted device based on the communication capability of the wireless network module of the vehicle-mounted device. In this way, the user can operate the optional upgrade method of the vehicle-mounted device, so that the terminal device responds to the operation of the optional upgrade method of the vehicle-mounted device and determines the upgrade method of the vehicle-mounted device from the optional upgrade methods.

[0088] That is, after the terminal device determines the optional upgrade methods, the terminal device can determine the upgrade method of the vehicle-mounted device from the optional upgrade methods through the user's operation.

[0089] In this way, when the MCU and MPU are able to communicate, the terminal device determines the optional upgrade method of the vehicle-mounted equipment based on the communication capability of the wireless network module, and then determines the upgrade method of the vehicle-mounted equipment through the user's operation, so that the vehicle-mounted equipment can be smoothly upgraded according to the user's needs.

[0090] In order to determine the optional upgrade mode of the vehicle-mounted device, in an optional embodiment, the terminal device determines the optional upgrade mode of the vehicle-mounted device according to the communication capability of the wireless network module of the vehicle-mounted device, which may include:

[0091] When the response message indicates that the wireless network module has the ability to communicate with the external device, the terminal device determines that the optional upgrade methods of the vehicle-mounted device are: an OTA upgrade method and a USB flash drive upgrade method.

[0092] It can be understood that the response message indicates that the wireless network module has the ability to communicate with external devices, that is, the vehicle-mounted device can communicate with external devices through its own wireless network module. The terminal device determines that the optional upgrade methods of the vehicle-mounted device can be OTA upgrade method and U disk upgrade method, that is, the OTA upgrade package can be downloaded through the wireless network module, or the U disk upgrade package can be obtained from the U disk by utilizing the interaction between the MCU and the MPU, thereby realizing software upgrade.

[0093] In this way, when the wireless network module has the ability to communicate with external devices, the user can choose an upgrade method from the OTA upgrade method and the USB flash drive upgrade method to upgrade the software of the vehicle-mounted device, providing the user with an optional upgrade method for the user to choose.

[0094] In addition, in order to determine the optional upgrade mode of the vehicle-mounted device, in an optional embodiment, the terminal device determines the optional upgrade mode of the vehicle-mounted device according to the communication capability of the wireless network module of the vehicle-mounted device, which may include:

[0095] When the response message indicates that the wireless network module does not have the ability to communicate with the external device, the terminal device determines that the optional upgrade methods of the vehicle-mounted device are: a USB flash drive upgrade method and a USB forced line flash upgrade method.

[0096] It can be understood that the response message indicates that the wireless network module does not have the ability to communicate with external devices, that is, the vehicle-mounted device cannot communicate with external devices through its own wireless network module, but can realize communication between the MCU and the MPU. The terminal device determines that the optional upgrade method of the vehicle-mounted device can be an upgrade method using a USB flash drive and an upgrade method using a USB forced line flash. That is, the USB flash drive upgrade package can be obtained from the USB flash drive through the interaction between the MCU and the MPU, and the terminal device can also obtain the forced line flash instruction through the USB interface, thereby realizing software upgrade.

[0097] In this way, when the wireless network module does not have the ability to communicate with external devices, the user can choose an upgrade method from the USB flash drive upgrade method and the USB forced wire flash upgrade method to upgrade the software of the vehicle-mounted device, providing the user with optional upgrade methods for the user to choose.

[0098] In order to upgrade the vehicle-mounted device according to the determined upgrade method, in an optional embodiment, S205 may include:

[0099] When the upgrade mode is OTA, the terminal device generates an upgrade message according to the upgrade mode and sends it to the vehicle-mounted device. The OTA upgrade package is sent to the vehicle-mounted device through the wireless network module of the vehicle-mounted device. The vehicle-mounted device receives the OTA upgrade package through the wireless network module of the vehicle-mounted device, and the vehicle-mounted device is OTA upgraded using the OTA upgrade package.

[0100] In the case where the upgrade method is a U disk upgrade method, the terminal device generates an upgrade message according to the upgrade method and sends it to the vehicle-mounted device. The vehicle-mounted device enters the U disk upgrade mode, sends a first prompt message to the terminal device, connects the U disk through the USB interface of the vehicle-mounted device to obtain a U disk upgrade package, and uses the U disk upgrade package to perform a U disk upgrade on the vehicle-mounted device;

[0101] When the upgrade method is USB forced wire flash, the terminal device generates an upgrade message according to the upgrade method and sends it to the vehicle-mounted device. The vehicle-mounted device enters the forced upgrade mode and sends a second prompt message to the terminal device. The terminal device sends a forced wire flash instruction to the vehicle-mounted device through the USB interface of the vehicle-mounted device. The vehicle-mounted device receives the forced wire flash instruction from the terminal device to perform a forced upgrade.

[0102] It can be understood that when the terminal device determines to adopt the OTA upgrade method, it generates an upgrade message and sends it to the vehicle-mounted device. In addition, the terminal device sends the OTA upgrade package to the vehicle-mounted device through the wireless network module of the vehicle-mounted device, so that the vehicle-mounted device uses the OTA upgrade package to perform OTA upgrade on the software system of the vehicle-mounted device.

[0103] When the terminal device determines to adopt the U disk upgrade method, it generates an upgrade message and sends it to the vehicle-mounted device. After receiving the upgrade message, the vehicle-mounted device enters the U disk upgrade mode and sends a first prompt message to the terminal device, wherein the first prompt message is used to prompt the user to insert the U disk. After receiving the first prompt message, the terminal device connects the U disk through the USB interface of the vehicle-mounted device, obtains the U disk upgrade package from the U disk, and then uses the U disk upgrade package to perform the U disk upgrade.

[0104] When the terminal device determines to adopt the upgrade method of USB forced line flash, it generates an upgrade message and sends it to the vehicle-mounted device. After receiving the upgrade message, the vehicle-mounted device enters the forced upgrade mode and sends a second prompt message to the terminal device, wherein the second prompt message is used to indicate that the vehicle-mounted device has entered the forced upgrade mode. After receiving the second prompt message, the terminal device sends a forced line flash instruction to the vehicle-mounted device through its own USB interface, so that the vehicle-mounted device is forced to upgrade according to the forced line flash instruction.

[0105] In this way, the steps for software upgrade of the vehicle-mounted device are different for different upgrade methods. Here, OTA upgrade, USB flash drive upgrade or forced line flash can be achieved through the interaction between the vehicle-mounted device and the terminal device.

[0106] With respect to the above OTA upgrade, in an optional embodiment, the vehicle-mounted device receives the OTA upgrade package through the wireless network module of the vehicle-mounted device, and performs OTA upgrade on the vehicle-mounted device using the OTA upgrade package, which may include:

[0107] The vehicle-mounted device receives the OTA upgrade package through the wireless network module and sends it to the MPU of the vehicle-mounted device;

[0108] After receiving the OTA upgrade package, the vehicle-mounted device triggers the OTA upgrade program through the MPU to upgrade the vehicle-mounted device.

[0109] It can be understood that the vehicle-mounted device receives the OTA upgrade package through the wireless network module. Since the wireless network module is connected to the MPU, after the wireless network module receives the OTA upgrade package, it sends it to the MPU. After the MPU receives the OTA upgrade package, it triggers the OTA upgrade program to upgrade the vehicle-mounted device.

[0110] In this way, the OTA upgrade package is received through the wireless network module, and the MPU triggers the OTA upgrade program, so that the vehicle-mounted device realizes OTA upgrade through interaction with the terminal device.

[0111] Furthermore, in order to implement the forced wire-flash upgrade, in an optional embodiment, the vehicle-mounted device enters the forced upgrade mode, receives the forced wire-flash instruction from the terminal device, and performs the forced wire-flash upgrade on the vehicle-mounted device, which may include:

[0112] After receiving the upgrade message, the vehicle-mounted device controls the MPU hardware of the vehicle-mounted device through the MCU of the vehicle-mounted device to make the MPU enter the forced upgrade mode, and sends the second prompt information to the terminal device;

[0113] The vehicle-mounted device receives a forced wire-flash instruction from the terminal device to perform a forced upgrade, which may include: the vehicle-mounted device receives a forced wire-flash instruction from the terminal device through a USB interface to perform a forced wire-flash upgrade.

[0114] It can be understood that after receiving the upgrade message, the MCU of the vehicle-mounted device controls the MPU hardware of the vehicle-mounted device to make the MPU enter the forced upgrade mode, and sends a second prompt message to the terminal device to prompt the terminal device that the vehicle-mounted device has entered the forced upgrade mode.

[0115] In addition, the vehicle-mounted device receives a forced wire flash command from the terminal device through the USB interface, and performs a forced wire flash upgrade according to the forced wire flash command.

[0116] In this way, the upgrade message is received by the MCU, and the MPU is forced to enter the upgrade mode by controlling the MPU hardware. The vehicle-mounted device receives the forced line flash command through the USB, so that the vehicle-mounted device can realize the forced line flash upgrade through interaction with the terminal device.

[0117] The following examples are used to illustrate the upgrade method described in one or more of the above embodiments.

[0118] This example uses the vehicle's OBD universal hardware interface and custom CAN message messages. When an unrecoverable software failure such as a black screen, system startup failure, or system firmware upgrade failure occurs in the central control system of the vehicle-mounted device, the diagnostic tool software on the personal computer (PC) sends a custom CAN message message to the vehicle's OBD interface to implement software upgrade and recovery of the central control system of the vehicle-mounted device. This can avoid dismantling the vehicle or the central control hardware to achieve upgrade and repair, improve the efficiency of after-sales maintenance, and reduce customer complaints.

[0119] At present, all intelligent network cars are equipped with a central control of intelligent network-connected vehicle equipment. The central control provides an operation interface for users through the connected display screen. During normal use, the central control may have the following abnormal situations:

[0120] 1. The display software is abnormal and causes a black screen

[0121] 2. The system cannot boot

[0122] 3. System firmware upgrade failed

[0123] 4. The touch screen cannot be touched

[0124] Among them, the above-mentioned abnormalities may not be restored by restarting the central control system and can only be restored by reflashing the central control system software.

[0125] This example is applicable to the above scenario. After an unrecoverable software exception occurs, a customized CAN message can be sent through the vehicle's OBD interface to upgrade the central control software and repair the exception.

[0126] Figure 3 A schematic diagram of an example of an optional upgrade system provided in an embodiment of the present application is shown in FIG. Figure 3 As shown, the upgrade system 300 may include: a vehicle-mounted central control 31; wherein the vehicle-mounted central control 31 may include: an MPU 311, an MCU 312 and a 4G module 313; the vehicle-mounted central control 31 is also provided with a USB interface 314, a CAN interface 315, a vehicle CAN line 316 and an OBD interface 317.

[0127] Among them, the vehicle-mounted central control 31 hardware includes two main control chips, MPU311 and MCU312. MPU311 and MCU312 communicate data through a universal asynchronous receiver / transmitter (UART) serial port connection. MCU312 is connected to the vehicle's CAN line 316 network through a CAN interface 315, and the vehicle's OBD interface 317 is also connected to the vehicle's CAN line 316 network.

[0128] CAN messages are sent to the vehicle CAN line 316 network through the OBD interface 317, and the message messages on the vehicle CAN line 316 network can be received by all controllers connected to the vehicle CAN line 316; similarly, the message messages sent by the on-board central control 31 to the vehicle CAN line 316 network can also be received by all devices connected to the vehicle CAN line 316.

[0129] The vehicle-mounted central control 31 provides a USB interface 314 and has networking function, and can perform local U disk system upgrades via USB, and can also perform OTA online upgrades via the network.

[0130] Figure 4 A flowchart of an example of an optional upgrade method provided in an embodiment of the present application is shown as follows: Figure 4 As shown, the upgrade method may include:

[0131] Example 1: When the vehicle has an unrecoverable black screen or cannot be started, connect the PC to the vehicle's OBD interface and the vehicle's central control performs the following steps:

[0132] S401: receiving a vehicle CAN network message;

[0134] S403: Determine whether it is an upgrade detection message? If yes, execute S405; if no, execute S406;

[0135] S404: The MPU processes other messages.

[0136] S405: MCU receives the message and executes S407;

[0137] S406: Determine whether it is a USB flash drive upgrade message? If yes, execute S408; if no, execute S409;

[0138] S407: Determine whether the heartbeat communication between MCU and MPU is normal? If yes, execute S410; if no, execute S411;

[0139] S408: The MPU triggers the central control system to enter the USB flash drive upgrade mode, and executes S412;

[0140] S409: Determine whether it is a hardware mandatory upgrade message? If yes, execute S413; if no, execute S414;

[0141] S410: Is the MPU checking the vehicle network normal? If yes, execute S415; if no, execute S416;

[0142] S411: MCU responds with a message that "USB forced line flash" needs to be executed.

[0143] S412: MCU replies with a message "the system enters the USB flash drive upgrade mode" and executes S417;

[0144] S413: MCU triggers the MPU to enter the hardware forced upgrade mode and executes S418;

[0145] S414: Determine whether it is an OTA upgrade message? Execute S419;

[0146] S415: The MPU replies with a message "MPU network is normal".

[0147] S416: The MPU replies with an "MPU network abnormality" message.

[0148] S417: Is the upgrade USB disk inserted? If yes, execute S420; if no, execute S417;

[0149] S418: The MCU replies with a message "the system enters the forced upgrade mode" and executes S421;

[0150] S419: The MPU enters the OTA upgrade mode and executes S422;

[0151] S420: Perform USB flash drive upgrade and execute S423;

[0152] S421: Determine whether to insert the USB cable for burning? If yes, execute S424; if no, execute S421;

[0153] S422: The MCU replies with a message "the system enters OTA upgrade mode" and executes S423.

[0154] S423: Determine whether the upgrade is completed? If yes, execute S425; if no, execute S423;

[0155] S424: Perform strong upgrade and burn-in, and execute S423;

[0156] S425: The MPU replies with an "upgrade completed" message.

[0157] That is to say, first, send an upgrade detection message to the vehicle's CAN network through the standard CAN diagnostic tool on the PC to detect the current status of the vehicle's central control software, and get the following:

[0158] If the central control system MCU and MPU can communicate normally: after receiving the CAN message, the central control MPU software first detects whether the system network is normal. If the network is normal, it replies the normal CAN message of the MPU network to the diagnostic tool, and the user chooses whether to perform OTA upgrade system or USB flash drive upgrade system to restore the vehicle computer; if the user chooses OTA recovery, the OTA upgrade message is sent to the central control through the diagnostic tool; after receiving the OTA upgrade message, the central control MPU triggers the MPU's OTA upgrade program for upgrade and recovery.

[0159] If the central control system MCU and MPU can communicate normally: After receiving the CAN message, the central control MPU software detects the system network abnormality, and replies the CAN message of the MPU network abnormality to the diagnostic tool. The user chooses whether to perform U disk upgrade recovery or USB forced line flash recovery. The following two situations can be obtained:

[0160] If the user sends a USB flash drive upgrade message through the diagnostic tool: After receiving the message, the central control MPU triggers the system to enter recovery (recovery) to execute the USB flash drive upgrade, and replies to the PC diagnostic tool with a message that the system enters the USB flash drive upgrade mode to prompt the user to insert the USB flash drive for automatic upgrade.

[0161] If the user sends a USB forced upgrade message through the diagnostic tool: After receiving the message, the central control MCU directly puts the MPU into hardware forced upgrade mode by pulling the MPU hardware. The MCU replies to the PC diagnostic tool with a message that the system has entered forced upgrade mode. The user connects the USB cable of the vehicle central control to the PC for forced line flashing.

[0162] If the central control system does not work: the MCU receives the diagnostic message and determines that the communication with the central control MPU is abnormal. The MCU replies with a USB forced line flash message to the diagnostic tool. The user sends a USB forced upgrade message through the diagnostic tool. After receiving the message, the central control MCU directly pulls the MPU hardware to make the MPU enter the hardware forced upgrade mode. The MCU replies with a message that the system has entered the forced upgrade mode to the PC diagnostic tool. The user connects the USB cable of the vehicle-mounted central control to the PC for forced line flash.

[0163] After the central control upgrade and recovery is completed, an upgrade success message is sent to the diagnostic tool.

[0164] Example 2:

[0165] The steps in Example 1 above are also applicable to system software upgrades when the vehicle's central control is completely normal, and can provide another way to trigger the upgrade process for 4S stores or factories.

[0166] Figure 5 A schematic diagram of an optional message format provided in an embodiment of the present application, such as Figure 5 As shown, the message message defined in this example is generated based on the standard CAN protocol. The message uses a group of messages consisting of 8 bytes. The message format includes:

[0167] Message code 1 and message code 2: define the type of message;

[0168] Data length: refers to the length of the valid data sent;

[0169] Data: Data consists of 3 bytes;

[0170] Check digit: The check digit is obtained by performing a specific calculation on the data bits;

[0171] Data end bit: The data end bit is represented by a specific character.

[0172] In this example, when an abnormality occurs in the vehicle's central control, the vehicle's central control upgrade can be triggered through the OBD interface to avoid dismantling the vehicle for repair; the optional upgrade mode of the vehicle computer can be detected through the OBD interface.

[0173] Through the above examples, the difficulty of system recovery and repair in the event of an abnormality in the vehicle central control is reduced; a method is provided to facilitate car manufacturers or 4S stores to upgrade the vehicle central control after sales.
