[0002] The system of a vehicle needs to download system update data from a server for update. Existing vehicle systems generally perform updates through Over-the-Air Technology (OTA).

[0003] In existing vehicle OTA, system update data is saved on the server, and then operators configure and notify the vehicle to perform OTA. After receiving the OTA request, the vehicle establishes a communication connection with the server and downloads the system update data from the server for system update.

[0004] However, since the system update of the vehicle is downloaded through a mobile communication network, such as the fourth-generation mobile communication network (4G), the fifth-generation mobile communication network (5G), etc. However, the communication quality of the mobile communication network is unstable and the cost is relatively high. When the vehicle is parked in a place with poor network signal, such as an underground parking garage, for OTA, it may be unable to download the complete system update data due to unstable network signal, resulting in update failure. And even if the network is stable, the high download cost of the mobile communication network will increase the cost of system update. Summary of the Invention

The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0049] As Figure 1 shown is the flowchart of a method for updating a vehicle system according to an embodiment of the present invention, including:

[0050] Step S101, receiving a hotspot connection request and a communication establishment request from a mobile terminal, and establishing a communication connection with the mobile terminal through the vehicle hotspot;

[0051] Step S102, downloading system update data from the mobile terminal, where the system update data is downloaded by the mobile terminal from a server and stored in the mobile terminal;

[0052] Step S103, performing system update based on the system update data.

[0053] Specifically, the present invention can be applied to an electronic device with processing capabilities, such as a controller of a vehicle. For example, an Electronic Control Unit (ECU) of a vehicle.

[0054] First, the vehicle executes step S101, receives a hotspot connection request and a communication establishment request from the mobile terminal, and establishes a communication connection with the mobile terminal through the vehicle hotspot.

[0055] Specifically, the mobile terminal can be a mobile phone. The hotspot is created by the vehicle, for example, created by the In-Vehicle Infotainment System (IVI) of the vehicle's head unit. The vehicle responds to the hotspot connection request, connects to the mobile terminal through the vehicle hotspot, and responds to the communication establishment request to establish a communication connection with the mobile terminal.

[0056] Then, step S102 is executed to download system update data from the mobile terminal. The system update data is downloaded from the server by the mobile terminal and saved in the mobile terminal.

[0057] Specifically, the mobile terminal pre-downloads and saves the system update data of the vehicle from the server. The system update data is the data to be used for updating the vehicle system. The vehicle system to be updated can be the head unit (DA) system or other systems of the vehicle.

[0058] The mobile terminal can pre-download the system update data from the server by means such as WIFI, thereby reducing communication costs. On the other hand, since the user can carry the mobile terminal, the user can carry the mobile terminal to an area with stable network to download the system update data, thereby avoiding the impact of unstable network on data download.

[0059] After the mobile terminal downloads the system update data of the vehicle, when the mobile terminal establishes communication with the vehicle hotspot, the vehicle downloads the system update data from the mobile terminal.

[0060] Finally, step S103 is executed to perform system update based on the system update data.

[0061] Specifically, the vehicle uses the existing system update method to perform system update based on the system update data obtained from the mobile terminal.

[0062] The present invention downloads the system update data from the server through the mobile terminal, then the vehicle provides a hotspot, and the mobile terminal establishes a communication connection with the vehicle, enabling the vehicle to download the system update data from the mobile terminal, avoiding the use of the mobile communication network, avoiding the inability to download due to unstable network, and also being able to save download costs.

[0063] Such as Figure 2The following is a flowchart of the operation of a vehicle system update method according to another embodiment of the present invention, including:

[0064] Step S201: Obtain the system update information of the vehicle from the server. When it is determined that a system update is required, start the vehicle hotspot, generate a QR code representing the hotspot connection parameters and communication establishment parameters, and display the QR code.

[0065] Step S202: Receive the hotspot connection request and communication establishment request from the mobile terminal, and establish a communication connection with the mobile terminal through the vehicle hotspot.

[0066] Step S203: Download the system update data from the mobile terminal. The system update data is downloaded from the server by the mobile terminal and stored in the mobile terminal.

[0067] Step S204: Perform a system update based on the system update data.

[0068] Specifically, first execute Step S201: Obtain the system update information of the vehicle from the server. When it is determined that a system update is required, start the vehicle hotspot, generate a QR code representing the hotspot connection parameters and communication establishment parameters, and display the QR code.

[0069] Specifically, the vehicle regularly obtains the system update information of the vehicle from the server. Based on the system update information, it is determined whether a system update is required. Since only the system update information is obtained, rather than the complete system update data, the amount of downloaded data is small. Therefore, even if the network signal is unstable, the system update information can still be obtained, and the communication cost is not high.

[0070] The system update information can be the vehicle version, and it is determined whether a system update is required by comparing the versions.

[0071] When it is determined that a system update is required, start the vehicle hotspot through, for example, the in-vehicle IVI system, generate a QR code representing the hotspot connection parameters and communication establishment parameters, and then display the QR code on the in-vehicle screen.

[0072] Among them, the hotspot connection parameters and communication establishment parameters can be wireless network (WIFI) feature information, host IP address, and communication port. The hotspot connection parameters include, but are not limited to: parameters such as WIFI SSID and WIFI password for establishing a hotspot connection. The communication establishment parameters include, but are not limited to: parameters such as host IP address and communication port for establishing a TCP Socket communication connection. Among them, WIFI is a wireless local area network (WLAN, Wireless Local Area Network) technology based on the IEEE 802.11 standard.

[0073] In one embodiment, generating a two-dimensional code for representing hotspot connection parameters and communication establishment parameters includes:

[0074] Uploading the hotspot connection parameters and communication establishment parameters to a server;

[0075] Receiving an identification code returned by the server, where the identification code is generated by the server according to the hotspot connection parameters and communication establishment parameters;

[0076] Generating a two-dimensional code according to the identification code.

[0077] Specifically, the vehicle uploads the hotspot connection parameters of the enabled hotspot and the communication establishment parameters for establishing a TCP Socket communication connection to the server. The server generates a unique identification code uniCode according to the hotspot connection parameters and communication establishment parameters. The identification code is stored corresponding to the hotspot connection parameters and communication establishment parameters in the server.

[0078] Then, the server returns the identification code to the vehicle, and the vehicle generates a corresponding two-dimensional code according to the identification code.

[0079] It should be noted that since the hotspot connection parameters, communication establishment parameters, identification code, and the amount of data to be transmitted when generating the two-dimensional code are very small, data transmission can be achieved even when the network is unstable.

[0080] In this embodiment, the hotspot connection parameters and communication establishment parameters are uploaded to the server. When parsing the two-dimensional code displayed by the vehicle, only the identification code can be obtained, and the hotspot connection parameters and communication establishment parameters cannot be directly obtained. Therefore, even if other illegal terminals obtain the two-dimensional code displayed by the vehicle, since the illegal terminals cannot establish a secure communication with the server, the illegal terminals cannot obtain the real hotspot connection parameters and communication establishment parameters, and thus cannot establish a communication connection with the vehicle, avoiding the intrusion of illegal terminals into the vehicle and improving security.

[0081] Then, after the mobile terminal obtains the hotspot connection parameters and communication establishment parameters, the mobile terminal generates a hotspot connection request and a communication establishment request based on the hotspot connection parameters and communication establishment parameters and sends them to the vehicle, triggering step S202, receiving the hotspot connection request and the communication establishment request of the mobile terminal, and establishing a communication connection with the mobile terminal through the vehicle hotspot.

[0082] Specifically, since the vehicle has enabled the hotspot, when the vehicle receives the hotspot connection request and the communication establishment request of the mobile terminal, due to the correct hotspot connection parameters and communication establishment parameters, a communication connection can be established with the mobile terminal through the vehicle hotspot.

[0083] After establishing a communication connection with the mobile terminal, step S203 is executed to download system update data from the mobile terminal, where the system update data is downloaded by the mobile terminal from the server and saved in the mobile terminal.

[0084] Finally, step S204 is executed to perform a system update based on the system update data.

[0085] When the vehicle in this embodiment determines that a system update is required, it turns on the hotspot and generates and displays a QR code representing hotspot connection parameters and communication establishment parameters. On the one hand, the QR code avoids directly displaying the parameters, improving security. At the same time, using the QR code can also facilitate connection without the user having to manually enter the parameters, improving convenience. By establishing a communication connection between the mobile terminal and the vehicle, the vehicle can download system update data from the mobile terminal, avoiding using the mobile communication network, avoiding the inability to download due to unstable network, and also saving download costs.

[0086] As Figure 3 shown is a flowchart of a method for a mobile terminal to assist a vehicle system update according to an embodiment of the present invention, including:

[0087] Step S301, obtain the system update information of the vehicle from the server, and when it is determined that a system update is required, download the system update data from the server;

[0088] Step S302, send a hotspot connection request and a communication establishment request to the vehicle;

[0089] Step S303, after establishing a communication connection with the vehicle through the vehicle hotspot, send the system update data to the vehicle, where the system update data is used for the vehicle to perform a system update.

[0090] Specifically, the present invention can be applied to a mobile terminal with processing capabilities. Preferably, the mobile terminal is a mobile phone.

[0091] The mobile terminal executes step S301 to obtain the system update information of the vehicle from the server, and when it is determined that a system update is required, download the system update data from the server.

[0092] Specifically, the mobile terminal obtains the system update information of the vehicle from the server. The system update information can be the vehicle version, and it is determined whether a system update is required by comparing the versions.

[0093] When it is determined that a system update is required, download system update data from the server. The mobile terminal can, for example, use WIFI or other means to pre-download system update data from the server, thereby reducing communication costs. On the other hand, since the user can carry the mobile terminal, the user can carry the mobile terminal to an area with stable network to download system update data, thus avoiding the impact of unstable network on data download.

[0094] After downloading the system update data, perform step S302 to send a hotspot connection request and a communication establishment request to the vehicle.

[0095] Specifically, the mobile terminal sends a hotspot connection request and a communication establishment request to the vehicle. The hotspot connection request includes hotspot connection parameters, and the communication establishment request includes communication establishment parameters. The hotspot connection parameters and the communication establishment parameters can be wireless network (WIFI) feature information, host IP address, communication port. The hotspot connection parameters include, but are not limited to: parameters such as WIFI SSID, WIFI password, etc. for establishing a hotspot connection. The communication establishment parameters include, but are not limited to: parameters such as host IP address, communication port, etc. for establishing a TCP Socket communication connection.

[0096] The vehicle responds to the hotspot connection request and the communication establishment request sent by the mobile terminal, establishes a connection with the vehicle, and then performs step S303. After establishing a communication connection with the vehicle, send the system update data to the vehicle, and the system update data is used for the vehicle to perform a system update.

[0097] In the present invention, the mobile terminal downloads system update data from the server, and then the vehicle provides a hotspot, and the mobile terminal establishes a communication connection with the vehicle, so that the vehicle can download system update data from the mobile terminal, avoiding the use of a mobile communication network, avoiding the inability to download due to unstable network, and also being able to save download costs.

[0098] As Figure 4 shown is a flowchart of the working process of a method for a mobile terminal to assist a vehicle in system update according to the present invention, including:

[0099] Step S401, obtain the system update information of the vehicle from the server, and when it is determined that a system update is required, download system update data from the server;

[0100] Step S402, in response to a scanning event of a two-dimensional code displayed by the vehicle, parse the two-dimensional code to obtain corresponding hotspot connection parameters and communication establishment parameters. The hotspot connection parameters are connection parameters of the vehicle hotspot started by the vehicle, and the communication establishment parameters are communication parameters for establishing a communication connection with the vehicle. The two-dimensional code is generated by the vehicle when it is determined that a system update is required, starts the vehicle hotspot, and generates a two-dimensional code for representing the hotspot connection parameters and the communication establishment parameters and displays it;

[0101] Step S403: Generate a hotspot connection request and a communication establishment request based on the hotspot connection parameters and the communication establishment parameters, and send them to the vehicle.

[0102] Step S404: After establishing a communication connection with the vehicle via the vehicle hotspot, send system update data to the vehicle, where the system update data is used for the vehicle to perform system updates.

[0103] Specifically, the mobile terminal executes Step S401 to obtain the system update information of the vehicle from the server. When it is determined that a system update is required, the system update data is downloaded from the server.

[0104] Specifically, the mobile terminal obtains the system update information of the vehicle from the server. The system update information can be the vehicle version, and it is determined whether a system update is required by comparing the versions.

[0105] When it is determined that a system update is required, the system update data is downloaded from the server.

[0106] In some embodiments, obtaining the system update information of the vehicle from the server and downloading the system update data from the server when it is determined that a system update is required includes:

[0107] Performing a security verification with the server. After the security verification passes, obtain the system update information of the vehicle from the server. When it is determined that a system update is required, download the system update data from the server.

[0108] Specifically, the mobile terminal and the server perform verification using an existing security verification method. After the verification passes, it is determined that the mobile terminal is a legitimate terminal, and then the system update information of the vehicle can be obtained from the server, and when it is determined that a system update is required, the system update data is downloaded from the server.

[0109] The user scans the QR code displayed by the vehicle with the mobile terminal. The mobile terminal executes Step S402. In response to the scanning event of the QR code displayed by the vehicle, the QR code is parsed to obtain the corresponding hotspot connection parameters and communication establishment parameters. The hotspot connection parameters are the connection parameters of the vehicle hotspot started by the vehicle, and the communication establishment parameters are the communication parameters for establishing a communication connection with the vehicle. The vehicle starts the vehicle hotspot when it is determined that a system update is required, generates a QR code representing the hotspot connection parameters and the communication establishment parameters, and displays it.

[0110] Specifically, after the vehicle activates the vehicle hotspot, the hotspot connection parameters and communication establishment parameters are obtained from the vehicle's system, and the vehicle generates a QR code representing the hotspot connection parameters and communication establishment parameters and displays it on, for example, the in-vehicle unit. After the user scans the QR code with the camera of the mobile terminal, step S402 is triggered to parse the QR code. Existing QR code parsing methods can be specifically used to parse the hotspot connection parameters and communication establishment parameters from the QR code.

[0111] In one embodiment, the parsing of the QR code to obtain the corresponding hotspot connection parameters and communication establishment parameters includes:

[0112] Parse the QR code to obtain an identification code;

[0113] Send the identification code obtained by parsing the QR code to the server;

[0114] Obtain the hotspot connection parameters and communication establishment parameters corresponding to the identification code obtained by parsing the QR code from the server.

[0115] Specifically, after the vehicle activates the vehicle hotspot, it sends the hotspot connection parameters and communication establishment parameters to the server, and the server generates a unique identification code uniCode for the hotspot connection parameters and communication establishment parameters. After the identification code is returned to the vehicle, the vehicle generates a QR code based on the identification code using existing QR code generation methods. After the user scans the QR code with the mobile terminal, the QR code is parsed, and the identification code obtained by parsing the QR code is obtained. The identification code obtained by parsing the QR code is sent to the server, and the server searches for the hotspot connection parameters and communication establishment parameters corresponding to the identification code obtained by parsing the QR code and returns them to the mobile terminal.

[0116] Since the connection between the mobile terminal and the server requires security verification, only a secure and legitimate mobile terminal can obtain the hotspot connection parameters and communication establishment parameters corresponding to the identification code, thereby preventing illegal terminals from obtaining the parameters.

[0117] This embodiment can prevent illegal terminals from obtaining the real hotspot connection parameters and communication establishment parameters, prevent illegal terminals from establishing a communication connection with the vehicle, prevent illegal terminals from invading the vehicle, and improve security.

[0118] After obtaining the hotspot connection parameters and communication establishment parameters, the mobile terminal executes step S403 to generate a hotspot connection request and a communication establishment request based on the hotspot connection parameters and communication establishment parameters and send them to the vehicle.

[0119] Specifically, the mobile terminal generates a hotspot connection request based on hotspot connection parameters. The vehicle responds to the hotspot connection request. After detecting that the hotspot connection parameters are correct, the mobile terminal establishes a hotspot connection with the vehicle. Then, the mobile terminal generates a communication establishment request based on communication establishment parameters. The vehicle responds to the communication establishment request. After the communication establishment parameters are correct, the vehicle establishes a TCP Socket communication connection with the mobile terminal.

[0120] Finally, the mobile terminal executes step S404. After establishing a communication connection with the vehicle through the vehicle hotspot, it sends system update data to the vehicle, and the system update data is used for the vehicle to perform system update.

[0121] In this embodiment, the mobile terminal establishes a communication connection with the vehicle by scanning the QR code provided by the vehicle. On the one hand, directly displaying parameters is avoided through the QR code, improving security. At the same time, using the QR code can also facilitate connection without the user manually inputting parameters, improving convenience. By establishing communication between the mobile terminal and the vehicle, the vehicle can download system update data from the mobile terminal, avoiding using the mobile communication network. While avoiding the inability to download due to unstable network, it can also save the download cost.

[0122] As Figure 5 shown is the flowchart of a vehicle system update method according to the best embodiment of the present invention, including:

[0123] Step S501, the operator configures a mobile-assisted OTA upgrade activity on the server 2 through the background portal interface (Portal) 1;

[0124] Step S502, the server 2 saves the mobile-assisted OTA upgrade activity data;
