[0034] Embodiment 1

[0035] Figure 1 This is a flow chart of a method for sending offline tasks to an unmanned vehicle provided in an embodiment of the present invention. This embodiment is applicable to the case of sending offline tasks to an unmanned vehicle. The method of this embodiment can be executed by an unmanned vehicle offline task sending device, which can be implemented in hardware and / or software. The device can be configured in the server end for sending offline tasks to an unmanned vehicle. The method specifically includes the following steps:

[0036] S110: When the unmanned vehicle service end is abnormal, obtain the first local data pre-cached by the mobile device and the second local data pre-cached by the vehicle self-test device.

[0037] Among them, see Figure 2In the prior art, a mobile device is usually used to send driving tasks to a server, and the server sends specific driving route information to the vehicle-mounted device. The vehicle-mounted device finally sends the driving route to the automatic driving system to control the unmanned vehicle to perform the driving task. In the prior art, the driving task is sent by the server. If an abnormality occurs in the server, it will affect the normal driving of the unmanned vehicle. Therefore, an embodiment of the present invention proposes a method for sending offline tasks to an unmanned vehicle that does not rely on the server.

[0038] Wherein, when it is determined that the unmanned vehicle service end is abnormal, the mobile device obtains the first local data that is pre-cached, and the on-board self-test device obtains the second local data that is pre-cached. Wherein, the mobile device may refer to a mobile phone or a mobile device end, and the first local data is obtained through the software on the mobile device to verify the driver of the unmanned vehicle; the first local data includes the unmanned vehicle authority data and the driver's identity information. The on-board self-test device may refer to a device integrated in the unmanned vehicle for self-testing the unmanned vehicle to ensure that the status of the unmanned vehicle is normal; the on-board self-test device obtains the second local data to provide offline operation support in the event of a server failure; the second local data includes line information within the area to which the unmanned vehicle belongs.

[0039] Specifically, each time the unmanned vehicle is started, the onboard self-checking device pulls all route information in the area from the server and stores it in the local cache. This data includes but is not limited to parameters such as route, speed, and destination, so as to provide offline operation support in the event of server failure. At the same time, in order to improve data security, these cached data are encrypted during storage to prevent data leakage.

[0040] The mobile device caches the driver's identity information and the driverless vehicle's permission data locally on the phone, ensuring that when the server is unavailable, the mobile device can still verify the driver's identity and operating permissions through the locally cached permission data. To ensure security, these cached data must also be encrypted.

[0041] S120: Authentication and authorization processing of the driver is performed through the first local data to establish a wireless communication connection between the mobile device and the unmanned vehicle.

[0042] The driver's identity information is verified by the unmanned vehicle authority data and driver identity information pre-cached in the mobile device, and the driver's operating authority is authorized to ensure that the current driver can operate the unmanned vehicle. After the current driver is verified, the mobile device establishes a connection with the unmanned vehicle by wireless transmission. The wireless transmission method includes establishing a connection with the unmanned vehicle via Bluetooth or wireless.

[0043] Optionally, to improve the safety of the unmanned vehicle, a dynamic key is used for double verification during the process of establishing a connection between the mobile device and the unmanned vehicle to ensure that only legitimate mobile devices can communicate with the unmanned vehicle.

[0044] S130: Transmit the second local data to a mobile device to determine a target driving route for the unmanned vehicle.

[0045] After the mobile device establishes a communication connection with the unmanned vehicle, the route information in the area to which the unmanned vehicle belongs, which is pre-cached by the on-board self-checking device, is sent to the mobile device, and the route is displayed in the mobile device for the driver to select the target driving route. For example, the on-board self-checking device sends all driving routes in the current area to the mobile device, and displays all route information in the mobile device; the driver determines the final target driving route based on the driving information such as the target driving points and intermediate points.

[0046] S140: Transmit the target driving route to an on-board self-checking device. When the on-board self-checking device determines that the unmanned vehicle is in a normal state, send the target driving route offline task to the unmanned vehicle automatic driving system.

[0047] Among them, after the driver determines the final target driving route, the target driving route is transmitted to the on-board self-test device through the mobile device, and the target driving route is sent to the unmanned vehicle automatic driving system through the on-board self-test device, thereby realizing offline task sending and automatic driving of the unmanned vehicle.

[0048] Optionally, after the target driving route is transmitted to the on-board self-inspection device, the on-board self-inspection device performs a self-inspection operation to ensure that the status of the unmanned vehicle is normal and meets the requirements for executing the mission.

[0049] The embodiment of the present invention provides a method for sending offline tasks for unmanned vehicles, which obtains first local data pre-cached by a mobile device and second local data pre-cached by an onboard self-test device when an abnormality occurs on the unmanned vehicle service end; authenticates and authorizes the driver through the first local data to establish a wireless communication connection between the mobile device and the unmanned vehicle; transmits the second local data to the mobile device to determine the target driving route of the unmanned vehicle; transmits the target driving route to the onboard self-test device, and when the onboard self-test device determines that the unmanned vehicle is in a normal state, sends the target driving route offline task to the unmanned vehicle automatic driving system. By adopting the technical solution of the embodiment of the present invention, when an abnormality occurs on the unmanned vehicle service end, the driver can still directly establish communication with the unmanned vehicle through the mobile device and send offline tasks, thereby maintaining the normal operation of the unmanned vehicle.

[0050] Embodiment 2

[0051] Figure 3 The flowchart of a method for issuing offline tasks to an unmanned vehicle provided in an embodiment of the present invention is shown in FIG. The embodiment of the present invention further optimizes the above embodiment on the basis of the above embodiment, and the embodiment of the present invention can be combined with various optional solutions in one or more of the above embodiments. Figure 3 As shown, the method for issuing offline tasks for unmanned vehicles provided in an embodiment of the present invention may include the following steps:

[0052] S310: When the unmanned vehicle service end is abnormal, obtain the first local data pre-cached by the mobile device and the second local data pre-cached by the vehicle self-test device.

[0053] S320: Authenticate and authorize the driver through the first local data to establish a wireless communication connection between the mobile device and the unmanned vehicle.

[0054] Among them, after determining that the unmanned vehicle server is abnormal, the unmanned vehicle vehicle authority data and driver identity information pre-cached in the mobile device are used to verify the driver identity information, and the driver's operating authority is authorized to establish a wireless communication connection between the mobile device and the unmanned vehicle.

[0055] As an optional but non-limiting implementation, the authentication and authorization processing of the driver through the first local data to establish a wireless communication connection between the mobile device and the unmanned vehicle includes but is not limited to steps A1-A2:

[0056] Step A1: The driver uses a mobile device to scan the QR code on the unmanned vehicle and verifies the driver's identity based on the driver's identity information included in the first local data.

[0057] Step A2: After the driver's identity verification is passed, the driver is authorized according to the unmanned vehicle authority data included in the first local data, and a communication connection is established between the mobile device and the unmanned vehicle.

[0058] Among them, when the driver finds that he cannot send tasks to the unmanned vehicle through the normal link, the mobile device will prompt the driver to switch the unmanned vehicle to stand-alone mode. In stand-alone mode, the driver scans the QR code on the unmanned vehicle, and the mobile device uses the locally cached permission information for a one-time verification to confirm whether the driver has the right to operate the vehicle; by scanning the QR code, the permission is quickly confirmed and the unmanned vehicle is connected, and the task is quickly sent, which simplifies the operation process and improves the user experience. If the permission verification is passed, the mobile device establishes a direct connection with the vehicle via Bluetooth or Wi-Fi. To improve security, a dynamic key is used for double verification during the connection process to ensure that only legitimate users can connect to the vehicle.

[0059] S330: Transmit the second local data to a mobile device to determine a target driving route for the unmanned vehicle.

[0060] Among them, after the mobile device is connected to the communication with the unmanned vehicle, the on-board self-test equipment transmits the line information within the area where the unmanned vehicle belongs to the mobile device, so that the driver can select the target driving route according to needs.

[0061] As an optional but non-limiting implementation, the transmitting of the second local data to the mobile device to determine the target driving route of the unmanned vehicle includes but is not limited to steps B1-B2:

[0062] Step B1: The mobile device receives the pre-cached second local data transmitted by the vehicle self-test device, and visually displays the second local data.

[0063] Step B2: Determine the target route information from the second local data according to the needs, and determine the target driving route of the unmanned vehicle according to the target route information; wherein the target route information includes the starting point, the intermediate point, the target point and the intermediate route information.

[0064] See also Figure 4 After the mobile device is successfully connected to the unmanned vehicle, the onboard self-checking device transmits the cached route information in the area where the unmanned vehicle belongs to the mobile device. After receiving the data, the mobile device will display the optional route information for the driver to select the route to determine the target driving route.

[0065] Optionally, AES encryption or TLS protocol is used during the second local data transmission process to prevent man-in-the-middle attacks and data tampering.

[0066] S340: Transmit the target driving route to the on-board self-test device. When the on-board self-test device determines that the unmanned vehicle is in a normal state, send the target driving route offline task to the unmanned vehicle automatic driving system.

[0067] After the driver selects and confirms the target driving route, the mobile device sends the task instructions to the on-board self-test device via Bluetooth or Wi-Fi. After receiving the task, the on-board self-test device first performs a self-test to ensure that the vehicle is in normal condition and meets the requirements for executing the task. After the self-test passes, the task instructions will be passed to the unmanned vehicle's automatic driving system, and the automatic driving system will execute the corresponding task based on the route information.

[0068] As an optional but non-limiting implementation, the method further includes but is not limited to steps C1-C2:

[0069] Step C1: monitor the driving state of the unmanned vehicle, and determine whether the unmanned vehicle has any abnormality according to the driving state; wherein the abnormal state of the unmanned vehicle includes encountering obstacles and sensor failure.

[0070] Step C2: When it is determined that the unmanned vehicle has an abnormality, the unmanned vehicle is switched to an emergency stop mode, and the unmanned vehicle is braked under safe conditions.

[0071] The vehicle has an emergency safety mode function when performing tasks. If an abnormal situation is detected,

[0072] If an obstacle is encountered or the sensor fails, the system will immediately switch to emergency stop mode and brake the unmanned vehicle under safe conditions to avoid accidents.

[0073] In addition, in stand-alone mode, the system only allows low-risk tasks, such as simple movement along a preset route, while disabling complex operations, such as high-speed or dynamic path tasks. To further ensure the safety of offline tasks, the system limits the task execution area in offline mode to ensure that the unmanned vehicle can only travel in a specific area, preventing the vehicle from entering an unsafe area if it loses control of the server.

[0074] As an optional but non-limiting implementation, the method further includes but is not limited to steps D1-D2:

[0075] Step D1: When the driver's identity is authenticated and authorized, the mobile device obtains the corresponding operation record and caches the operation record in a local log.

[0076] Step D2: After the unmanned vehicle service end resumes normal operation, the operation record is uploaded to the service end.

[0077] Among them, when the driver's identity is authenticated and authorized, the mobile device obtains the corresponding operation record and caches the operation record in the local log. All operation records (such as task issuance, permission verification, etc.) will be recorded in the local logs of the mobile device and the vehicle self-test device, so that they can be uploaded after the connection with the server is restored for subsequent auditing and security tracking. The system also has an abnormal behavior detection function. If there are abnormal situations such as multiple connection failures, the task issuance process will be automatically interrupted.

[0078] The embodiment of the present invention provides a method for issuing offline tasks for unmanned vehicles. By storing local data in mobile devices and on-board self-test devices, the normal operation of the system can be guaranteed even if the server is unavailable, thereby improving the reliability of the system. Task issuance is achieved through Bluetooth or Wi-Fi, without relying on external networks, ensuring that the unmanned vehicle can perform simple tasks even when the network is interrupted. Multiple security measures are used, including data encryption, double verification, permission control, operation logs, and anomaly detection, to ensure the security of the offline task issuance process and prevent unauthorized access and operation.
