Abstract
Description
Technical Field
[0001] This invention relates to the field of vehicle control, specifically to a vehicle control method, vehicle-mounted equipment, and vehicle. Background Technology
[0002] As cars evolve into intelligent mobile spaces, scenarios involving multiple users sharing vehicles, such as family cars, corporate fleets, and car rentals, are increasing, creating a demand for refined permission management of different user accounts to ensure vehicle safety, protect privacy, and improve management efficiency.
[0003] In related technologies, when triggering intervention through electronic fences, the intervention action is typically triggered immediately when a vehicle crosses the fence's range, such as limiting power output or locking the vehicle. While this one-size-fits-all, single-threshold triggering mechanism can provide some degree of security and area control, such as preventing vehicle theft or deviation from preset routes, it has many drawbacks in practical applications.
[0004] First, this approach lacks flexibility and intelligence. In some situations, a vehicle might simply be due to navigation errors, temporary obstacle avoidance, or a brief, unintentional transgression near a fence boundary. Immediately triggering severe interventions such as limiting power or locking the vehicle could not only unnecessarily disrupt normal driving but also pose safety hazards under certain road conditions, such as suddenly losing power at a busy intersection or while driving at high speed.
[0005] Secondly, for vehicle managers, this simple triggering logic is not conducive to refined management. It cannot distinguish the specific context, distance, and duration of a vehicle crossing the boundary, which may lead to a large number of unnecessary alarms and intervention operations, increasing management costs and complexity, and may also reduce user experience. Summary of the Invention
[0006] In view of the shortcomings of the prior art, the purpose of this application is to provide a vehicle control method, vehicle-mounted equipment and vehicle, which aims to achieve refined vehicle management.
[0007] In a first aspect, embodiments of this application provide a vehicle control method, comprising: Obtain the vehicle's current location and the geofence range; In response to the vehicle's current location exceeding the electronic fence range, a prompt message is generated and sent to the interactive terminal; In response to the vehicle's current location being more than or equal to a first preset distance beyond the electronic fence range, and / or the duration of the vehicle being beyond the electronic fence range being more than or equal to a first preset duration, intervention information is generated and sent to the control terminal.
[0008] In the above technical solution, when the vehicle's current location exceeds the electronic fence's range, a prompt message is generated and sent to the interactive terminal to alert of potential risks, but no intervention action is taken. This facilitates adaptation to non-malicious boundary crossing scenarios such as navigation deviations and temporary avoidance, reducing interference with normal driving. Furthermore, both the distance the vehicle's current location exceeds the electronic fence's range and the duration of the vehicle's exceeding the range are used as dual triggering conditions. Intervention is initiated only when the distance and / or duration reach preset thresholds, thus achieving a tiered design from mild prompts to mandatory intervention. This ensures safety without affecting normal usage scenarios, enabling refined vehicle management. Moreover, it enables automatic risk identification and tiered processing, reducing the cost of manual intervention.
[0009] In one embodiment, the range of the electronic fence is determined based on the driver's permission information.
[0010] In the above technical solution, the electronic fence range closely matches the driver's actual permissions, avoiding unreasonable restrictions or insufficient control over drivers with different permissions due to a uniform fence. It allows for direct definition of driving boundaries for different drivers through permission configuration, eliminating the need to repeatedly set up fences for individuals and reducing management complexity. It is suitable for multi-driver scenarios such as corporate fleets, rental vehicles, and car-sharing, enabling refined management.
[0011] In one embodiment, the electronic fence range corresponding to drivers with different permissions is set through at least one of a vehicle-mounted interactive device, a cloud management platform, and a mobile terminal.
[0012] The above technical solution supports multi-channel settings on the vehicle, cloud, and mobile terminals, adapting to different usage scenarios. The cloud management platform supports batch distribution of fence configurations for drivers with different permissions, adapting to multi-user scenarios such as corporate fleets and rental vehicles; the real-time setting function of the vehicle-side interaction device and mobile terminal can respond to temporary permission adjustment needs and reduce process waiting time.
[0013] In one embodiment, generating a prompt message in response to the vehicle's current location exceeding the electronic fence range specifically includes: generating a first prompt message in response to the vehicle's current location exceeding the electronic fence range, the first prompt message being used to prompt the driver that the vehicle has exceeded the electronic fence range; generating a second prompt message in response to the vehicle's current location exceeding the electronic fence range by a distance greater than or equal to a second preset distance, and / or the duration of the vehicle exceeding the electronic fence range being greater than or equal to a second preset duration, the second prompt message being used to prompt the administrator that the vehicle has exceeded the electronic fence range.
[0014] In the above technical solution, a first alert is generated when the vehicle's current location exceeds the electronic fence's range. This means that as soon as the vehicle crosses the boundary, a first alert is sent to the driver, allowing them immediate awareness of the violation and sufficient time to adjust their route, preventing escalation of risk or subsequent intervention due to information delays. Simultaneously, a second alert is sent to the administrator only when the distance or duration of the boundary violation reaches preset thresholds, reducing invalid alarms for minor boundary crossings. By combining driver self-correction with administrator supervision and intervention, minor boundary crossings rely on driver self-adjustment, while administrator intervention occurs when the risk escalates. This approach reduces management costs while ensuring effective control.
[0015] In one embodiment, in response to the vehicle's current location exceeding the electronic fence range by a distance greater than or equal to a first preset distance, and / or the duration of the vehicle exceeding the electronic fence range being greater than or equal to a first preset duration, generating intervention information specifically includes: in response to the vehicle's current location exceeding the electronic fence range by a distance greater than or equal to a first preset distance, and / or the duration of the vehicle exceeding the electronic fence range being greater than or equal to a first preset duration, generating functional restriction information, the functional restriction information being used to restrict at least one of the vehicle's entertainment functions, maximum driving speed, and power output capability; in response to the vehicle's current location exceeding the electronic fence range by a distance greater than or equal to a third preset distance, and / or the duration of the vehicle exceeding the electronic fence range being greater than or equal to a third preset duration, generating intervention control information, the intervention control information being used to control the vehicle to stop and prohibit the vehicle from restarting; the third preset distance is greater than the first preset distance, and the third preset duration is greater than the first preset duration.
[0016] In the aforementioned technical solution, a tiered intervention approach, ranging from functional restrictions to mandatory stopping, is applied based on progressive thresholds for exceeding the boundary distance and duration. This avoids applying uniformly harsh measures to boundary-crossing behaviors of varying risk levels, achieving precise control through escalating risks and intensified interventions. Specifically, the functional restriction information only limits entertainment functions, maximum speed, or power output, without affecting the vehicle's basic driving capabilities. This serves to remind the driver to correct their route while avoiding driving risks caused by sudden mandatory interventions. The intervention control information targets severe boundary-crossing scenarios, minimizing safety hazards to the greatest extent possible.
[0017] In one embodiment, the intervention control information is further used to control the operation of the vehicle audio-visual acquisition equipment to collect audio-visual data inside and / or outside the vehicle.
[0018] The aforementioned technical solution collects audio and video data from both inside and outside the vehicle, providing direct evidence for subsequent determination of liability for boundary violations and dispute resolution. Furthermore, administrators can use the collected audio and video data to instantly understand the actual situation after a vehicle is forcibly stopped, avoiding delays or misjudgments due to missing information.
[0019] In one embodiment, the method further includes: simultaneously generating first confirmation information when generating the prompt information, the first confirmation information being used for the driver to confirm whether to request not to execute the electronic fence control strategy, and sending the first confirmation information to the vehicle-side interactive device for the driver to confirm.
[0020] In the aforementioned technical solution, when drivers encounter reasonable boundary-crossing scenarios such as emergency avoidance or temporary task adjustments, they can proactively request that the control policy not be executed, avoiding the inconvenience caused by a one-size-fits-all approach. This setting reduces ineffective management and disputes, allows drivers to proactively confirm exceptions, helps administrators quickly distinguish between malicious boundary crossings and reasonable exemptions, and reduces user complaints and management costs caused by unreasonable intervention. Furthermore, it can better adapt to diverse special scenarios, covering unconventional scenarios such as emergency medical care, temporary route changes, and responses to sudden road conditions.
[0021] In one embodiment, the method further includes: in response to a driver's confirmation request not to execute the electronic fence control policy, generating second confirmation information, the second confirmation information being used for an administrator to confirm whether to execute the electronic fence control policy, and sending the second confirmation information to an interactive terminal for the administrator to confirm.
[0022] In the above technical solution, the administrator can receive a second confirmation message from the driver requesting not to execute the electronic fence control strategy. By combining real-time traffic conditions, task requirements, driver qualifications and other information, the administrator can make a comprehensive judgment, review and approve reasonable requests such as emergency avoidance, and promptly reject illegal requests, thus achieving flexible management and control.
[0023] Secondly, embodiments of this application also provide a vehicle infotainment device, including a processor and a memory, wherein the processor is used to execute computer programs or instructions stored in the memory, so that the vehicle infotainment device implements the above-described vehicle control method.
[0024] Thirdly, embodiments of this application also provide a vehicle including the aforementioned vehicle-mounted equipment.
[0025] This application has the following beneficial effects: The control method provided in this application generates a prompt message when the vehicle's current location exceeds the range of the electronic fence, and sends the prompt message to the interactive terminal to alert it to potential risks, but does not perform any intervention. It uses the distance the vehicle's current location exceeds the electronic fence range and the duration of the vehicle's exceeding the electronic fence range as trigger conditions, initiating intervention only when the distance and / or duration reach preset thresholds. This achieves a tiered design from mild prompts to mandatory intervention, ensuring safety without affecting normal usage scenarios, and realizing refined vehicle management. Furthermore, it enables automatic risk identification and tiered processing, reducing the cost of manual intervention. Attached Figure Description

[0029] The terms “first,” “second,” etc., are used for descriptive purposes only and have no sequential or technical meaning, nor should they be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.
[0030] In the embodiments of this application, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.
[0031] The embodiments of this application are described below with reference to the accompanying drawings.
[0032] Please refer to Figure 2 , Figure 2 This is a schematic diagram of the structure of a vehicle disclosed in an embodiment of this application. The vehicle 100 includes an in-vehicle infotainment system 10. The vehicle can be, but is not limited to, a pure electric vehicle (PEV / BEV), a hybrid electric vehicle (HEV), a range-extended electric vehicle (REEV), a plug-in hybrid electric vehicle (PHEV), a new energy vehicle, or a gasoline-powered vehicle.
[0033] Please refer to Figure 2 , Figure 2 This is a schematic diagram of the structure of a vehicle infotainment device provided in an embodiment of this application. The vehicle infotainment device 10 includes a processor 11 and a memory 12. The processor 11 is used to execute computer programs or instructions stored in the memory 12 to enable the vehicle infotainment device 10 to implement the vehicle control method described below. Exemplarily, the processor 11 typically controls the overall operation of the vehicle infotainment device 10, and the memory 12 is configured to store instructions and applications executable by the processor 11.
[0034] In some embodiments, please refer to Figure 2 The vehicle-mounted device 10 also includes a communication interface 13, which enables the electronic device to communicate with other terminals or servers via a network. Data can be transmitted between the processor 11, the memory 12, and the communication interface 13 via a bus 14.
[0035] In existing technologies, when a vehicle 100 triggers intervention via an electronic fence, the intervention is typically triggered immediately upon the vehicle exceeding the fence's boundaries, such as limiting power output or locking the vehicle. While this one-size-fits-all, single-threshold triggering mechanism can provide some security and area control, such as preventing vehicle theft or deviation from preset routes, it has several drawbacks in practical applications. First, this method lacks flexibility and intelligence. In some cases, a vehicle may have only briefly and unintentionally crossed the fence boundary due to navigation deviation, temporary obstacle avoidance, or a brief incursion. Immediately triggering severe interventions such as limiting power or locking the vehicle could not only unnecessarily disrupt normal vehicle operation but also pose safety hazards under specific road conditions, such as sudden loss of power at busy intersections or at high speeds. Second, for vehicle managers, this simple triggering logic is not conducive to refined management. It fails to distinguish the specific context, distance, and duration of the vehicle's boundary crossing, potentially leading to numerous unnecessary alarms and interventions, increasing management costs and complexity, and possibly degrading the user experience.
[0036] Therefore, in order to solve the above problems and achieve refined management of vehicle electronic fences, this application provides a vehicle control method.
[0037] Please refer to Figure 3 , Figure 3 This is a flowchart illustrating one implementation of the vehicle control method disclosed in this application. The method includes: acquiring the current location of the vehicle and the range of an electronic fence; generating a prompt message and sending the prompt message to an interactive terminal in response to the current location of the vehicle exceeding the range of the electronic fence; generating intervention information and sending the intervention information to a control terminal in response to the current location of the vehicle exceeding the range by a distance greater than or equal to a first preset distance, and / or the duration of the vehicle exceeding the range of the electronic fence being greater than or equal to a first preset duration.
[0038] By employing the vehicle control method of this application embodiment, when the vehicle's current position exceeds the range of the electronic fence, a prompt message is generated and sent to the interactive terminal to alert of potential risks without executing any intervention actions. This facilitates adaptation to non-malicious boundary crossing scenarios such as navigation deviations and temporary avoidance, reducing interference with normal driving. Furthermore, using both the distance the vehicle's current position exceeds the electronic fence range and the duration of the vehicle's exceeding the electronic fence range as dual triggering conditions, intervention is initiated only when the distance and / or duration reach preset thresholds. This achieves a tiered design from mild prompts to mandatory intervention, ensuring safety without affecting normal usage scenarios and realizing refined vehicle management. Moreover, it enables automatic risk identification and tiered processing, reducing the cost of manual intervention.
[0039] In one example, the range of the electronic fence is determined based on the driver's permission information.
[0040] The electronic fence's range closely matches the driver's actual permissions, avoiding unreasonable restrictions or insufficient control over drivers with different permissions due to a uniform fence. It allows for direct definition of driving boundaries for different drivers through permission configuration, eliminating the need to repeatedly set up fences for individuals and reducing management complexity. It is suitable for multi-driver scenarios such as corporate fleets, rental vehicles, and car-sharing, enabling refined management.
[0041] Optionally, the permission information includes administrator permissions and non-administrator permissions. It should be noted that administrators can be not only the vehicle owner but also other individuals under multiple accounts associated with the vehicle. The vehicle owner can configure administrators for the accounts authorized for vehicle sharing on the vehicle's infotainment system or the mobile application app linked to the vehicle; there can be one or more administrators. Specifically, senior administrators and regular administrators can be set, with different levels of administrators having different management permissions for other accounts. Senior administrator accounts have management permissions such as geofence management for non-owner authorized accounts; regular administrators do not have this management permission by default. The vehicle owner can also set specific functional permission ranges for each administrator and supports adding, deleting, and modifying permissions. The vehicle owner and accounts granted geofence management permissions are both administrators with geofence management permissions.
[0042] Optionally, the driver's permission information can be confirmed based on facial recognition, voiceprint recognition, remote control App login authentication, or Bluetooth key contactless login authentication.
[0043] Optionally, administrators with geofence management permissions can log in to the vehicle system via methods including but not limited to facial recognition, voiceprint recognition, remote control app QR code scanning, or Bluetooth key contactless login. During the login process, the vehicle system checks whether the account has geofence management permissions; if so, the identity is automatically synchronized upon successful login. Multi-account geofence permission management can then be implemented, allowing the setting of drivable and inaccessible areas for specific accounts.
[0044] In one example, the electronic fence range corresponding to drivers with different permissions is set through at least one of the vehicle-mounted interactive device, cloud management platform and mobile terminal.
[0045] This method supports multi-channel settings on the vehicle, cloud, and mobile terminals, adapting to different usage scenarios. The cloud management platform supports batch distribution of fence configurations for drivers with different permissions, adapting to multi-user scenarios such as corporate fleets and rental vehicles; the real-time setting function of the vehicle-side interaction device and mobile terminal can respond to temporary permission adjustment needs and reduce process waiting time.
[0046] Optionally, electronic fences can be set up via the vehicle-mounted interactive device's infotainment system. The management page integrates a high-precision map view and overlays the vehicle's real-time location. The interface provides multiple function buttons, such as "Create Fence," "Edit Fence," "Delete Fence," and "Multi-Account Fence Management." Administrators can click "Create Fence" and then manually draw the area on the map, supporting arbitrary shapes such as circles and polygons to define allowed or prohibited areas. During drawing, fine-tuning is possible using two-finger zooming and panning, and each vertex of the electronic fence can be displayed as a draggable control point. These control points can be dragged to fine-tune the shape of the electronic fence to ensure the area perfectly matches expectations. In addition to manual drawing, areas can be set by clicking and selecting, or by inputting information. Locations can be selected at the semantic tag level, such as home, company, school, etc., and administrative regions (province, city, district, etc.). Precise single or multiple points, as well as continuous routes (start point, end point, waypoints, etc.), can also be entered. Extended ranges can be set for these precise locations or routes, such as a range of 3 kilometers from the point. Additionally, administrators need to configure the geofence type, such as setting a non-drivable area or a drivable area. One or more geofences can be set to form a geofence group. Finally, the system converts the screen coordinates into a WGS-84 latitude and longitude coordinate sequence via a map application programming interface and stores it.
[0047] WGS-84 stands for World Geodetic System 1984. It is a widely accepted standard for geodesy. It defines the shape, size, and gravitational field of the Earth and serves as the reference for the Global Positioning System (GPS). Latitude and longitude coordinate sequences are typically based on geographic coordinates derived from this standard.
[0048] Once the geofence is set up, corresponding accounts will be bound, and multi-level permission granularity settings such as time and driving mode will be configured. A tiered control strategy will also be configured for this binding relationship. Regarding account binding, the administrator can choose to set this geofence for one or more target user accounts authorized to use the vehicle. For further granular settings, the administrator can also set the effective time for each geofence, such as allowing account A to travel from home to the company area from 7:00 to 20:00 on weekdays, and disabling it at other times, or restricting driving routes, such as allowing account B to drive within the city limits but prohibiting them from driving on highways. Regarding the tiered control strategy configuration for this binding relationship, various trigger conditions, vehicle actions, notification methods (App, SMS, email, phone, etc.), and notification recipients (one or more can be selected, and different recipients can be selected for notification under different levels of instructions) can all be freely configured.
[0049] After the detailed settings are completed, the system packages a series of data, including the latitude and longitude coordinates of the geofence, the bound account ID, and the hierarchical control policies, into a policy file, stores it in the vehicle's non-volatile memory, and simultaneously uploads it to the cloud. Subsequently, when the designated account uses the vehicle, the system compares the vehicle's current location and other status information with all bound geofence data and hierarchical control policies through the vehicle's positioning and data acquisition module. When the vehicle's status is determined to meet the triggering conditions of any hierarchical control policy, the system generates and executes the corresponding hierarchical vehicle control command to control the vehicle or issue a warning, and simultaneously notifies the designated administrator.
[0050] Optionally, geofences can be set up via voice control on the vehicle's interactive device. Specifically, administrators with geofence management permissions log in to the vehicle's infotainment system using methods including but not limited to facial recognition, voiceprint recognition, remote control app QR code scanning, or Bluetooth key-based contactless login. During the login process, the vehicle's infotainment system checks whether the account has geofence management permissions; if so, the identity is automatically synchronized upon successful login. Multi-account geofence permission management can then be implemented, allowing the setting of drivable and non-drivable areas for specific accounts.
[0051] Then, during vehicle use, you can say the wake-up phrase: "Hello XX, I want to set up a geofence," where XX is the name of the voice assistant. The vehicle's voice recognition module will then be activated. The administrator can then issue further commands, including: Voice settings can define the geographical range of the electronic fence, which can be a semantic tag-level location, such as home, company, school, etc., or an absolute single point or multiple points, as well as a continuous route (start point, end point, waypoint, etc.), and the extension range of a precise location point or route can be set, such as the extension range of the point within 1 kilometer.
[0052] Voice commands can be used to set the type of electronic fence, such as a no-drive zone or a driveable zone.
[0053] The validity period of the electronic fence can be set via voice, such as 30 days.
[0054] Voice commands can be used to bind specific target accounts to the electronic fence.
[0055] The speech recognition system converts speech into text, which is then parsed by the Natural Language Processing (NLP) unit to extract key information. This key information includes, but is not limited to: the geographic scope of the geofence (including landmark name, relative location, absolute address, route, and extension range), geofence type, validity period, and linked account. It's important to note that when semantic locations such as "home" or "company" are mentioned, the system will query the frequently used address book or navigation history to resolve them into specific latitude and longitude coordinates. For vague descriptions such as "surrounding area" or "nearby," the system uses a default value (e.g., a radius of 1 kilometer) or clarifies the desired range by asking "How large is the area you wish to cover?" Administrators can continuously refine the geofence settings through multiple rounds of dialogue.
[0056] The geographical description parsed by the voice recognition system is converted into a WGS-84 latitude and longitude coordinate sequence by calling the map application interface and stored, and a complex polygon electronic fence covering all road segments is automatically generated.
[0057] It's important to note that after the geofence and user binding settings are complete, the voice assistant proactively asks the administrator for specific rules. The system then automatically generates a tiered policy based on the administrator's feedback and understanding their intent. If the administrator's feedback is vague, the voice assistant can intelligently recommend tiered policies, allowing users to easily confirm or fine-tune complex policies. For example, if the administrator says, "You should warn them if they cross the boundary, and if they still don't listen, tell me immediately. It's best to check where they've gone," the system automatically generates a tiered policy after understanding the intent. Simultaneously, the system provides a policy summary via voice feedback, such as, "Understood. I have set up protection: warn them immediately if they cross the boundary; if they don't return after 10 minutes, I will notify you; if they are still violating the rules after 20 minutes, I will activate the dashcam for continuous recording, and take multiple photos of the vehicle's surroundings after it stops. Do you confirm this setting?" When the administrator says "confirm," the system saves the settings. The system packages the geofence's latitude and longitude coordinates, the bound account ID, control policies, and other data into a policy file, stores it in the vehicle's non-volatile memory, and simultaneously uploads it to the cloud. When a user's vehicle deviates from the designated driving range, the system will implement control measures or issue a warning according to the policy, and simultaneously notify the designated administrator.
[0058] Optionally, an electronic fence can be set up via a mobile terminal. Specifically, both the vehicle owner and the account granted electronic fence management privileges are administrators with such privileges.
[0059] Administrators with geofence management privileges can log in to the application app on the mobile terminal for remotely controlling vehicles using methods including but not limited to passwords and verification codes. During the login process, the app checks whether the account has geofence management privileges; if so, the account's identity is automatically synchronized upon successful login. Then, users can access "Multi-Account Geofence Management" to manage geofence permissions for multiple accounts, setting the permitted and prohibited driving areas for specific accounts.
[0060] The vehicle multi-account geofence management page integrates a map view and overlays the vehicle's real-time location. Similar to the vehicle infotainment system settings, the app's multi-account geofence management interface offers multiple function buttons, such as create geofence, edit geofence, delete geofence, and multi-account geofence management. Administrators can click "Create Geofence" and then manually draw the area on the map, supporting arbitrary shapes like circles and polygons to define allowed or prohibited areas. During drawing, users can zoom in and out using two fingers and pan the map for fine-tuning. The geofence vertices can be displayed as draggable control points, allowing for precise adjustments to the geofence shape to ensure the area perfectly matches expectations. In addition to manual drawing, users can also select or input areas. They can choose semantic tags such as home, company, school, etc., select administrative regions (province, city, district, etc.), or input precise single or multiple points, as well as continuous routes (start point, end point, waypoints, etc.). The app also supports setting extension ranges for these precise locations or routes, such as a 3-kilometer extension range. Additionally, administrators need to configure the geofence type, such as setting a non-drivable area or a drivable area. One or more geofences can be set to form a geofence group. Finally, the system converts the screen coordinates into a WGS-84 latitude and longitude coordinate sequence via a map application programming interface and stores it.
[0061] After the geofence is set up, the administrator can select one or more accounts authorized to use the vehicle to bind to this geofence. The administrator can also set further requirements such as the geofence's effective time and driving route preference restrictions, and configure a tiered control strategy for this binding relationship. Regarding the configuration of the tiered control strategy, various trigger conditions, vehicle actions, notification methods (App, SMS, email, telephone, etc.), and notification recipients (one or more per level of instruction, and different recipients can be selected for different levels of instructions) can all be freely configured. The tiered control strategy defines a series of progressively escalating vehicle control commands to be executed under different conditions such as initial triggering, re-triggering, or continuous violation. These control commands include multiple levels from low to high, and various commands can be customized. Levels can be added / deleted, and the trigger conditions, actions, and notification methods for each level can be set.
[0062] Final Confirmation and Implementation: After clicking "Confirm and Save," the application (App) sends the created geofence data, bound account ID, control policies, etc., to the cloud server via the network. The cloud server communicates with the vehicle's vehicle networking module (T-Box) to synchronously distribute the data to the target vehicle and store it in the vehicle's in-vehicle system's non-volatile memory. The corresponding account holder can then apply the designed geofence rules the next time the vehicle starts or at the time set according to the policy. Any adjustments to the designed geofence range and hierarchical control policies require an administrator with geofence management permissions to modify or delete the geofence range and control policies via a mobile terminal or the vehicle's in-vehicle system.
[0063] Optionally, fleet geofences and tiered control policies can be managed in batches through a cloud-based backend, facilitating efficient and unified large-scale fleet management for corporate fleets, car rental companies, and car-sharing companies. Specifically, administrators with geofence management permissions log in to the web-based cloud backend management platform using methods including but not limited to passwords and verification codes. During the login process, the system checks whether the account has geofence management permissions; if so, the identity is automatically synchronized upon successful login. Then, users can access the vehicle geofence management page to batch configure geofences and tiered control policies for multiple accounts.
[0064] The vehicle geofence management page integrates a map view and overlays the real-time vehicle location. This page provides multiple function buttons, such as: Create Fence, Edit Fence, Delete Fence, and Fence Management. Administrators can click "Create Fence" and then manually draw the area on the map interface, supporting the drawing of any shape such as circles or polygons to define allowed or prohibited areas. During drawing, the map can be zoomed in, zoomed out, and panned for fine-tuning. The vertices of the geofence can be displayed as draggable control points, allowing for fine-tuning of the geofence shape to ensure the area perfectly matches expectations. In addition to manual drawing, the page also supports setting areas through click selection and input. Users can select semantic label-level locations (such as "Company"), administrative regions (province, city, district, etc.), or precise single or multiple points, as well as continuous routes (start point, end point, waypoints, etc.). They can even input latitude and longitude coordinates and set extension ranges for these precise locations or routes, such as an extension range of 1 kilometer. In addition to manual drawing, click selection, and input, the system also supports batch importing single or multiple locations, routes, latitude and longitude coordinates, etc., to create fences. Administrators also need to configure settings such as selecting each electronic fence type. One or more fences can be set to form a fence group.
[0065] After the geofence is set up, administrators can use the filtering function to select specific cities, vehicle models, etc., to bind corresponding vehicles in batches. Manual input of license plate numbers, vehicle identification numbers (VINs), or TUIDs is also supported for vehicle binding. Importing vehicle information for batch vehicle binding is also supported. Administrators can also set further requirements such as geofence activation time and route preference restrictions, and configure tiered control strategies for this binding relationship. Regarding the configuration of tiered control strategies, various trigger conditions, vehicle actions, notification methods (backend push notifications, App, SMS, email, telephone, etc.), and notification recipients (one or more can be selected, and different personnel can be selected for notification under different levels of instructions) can all be freely configured. The tiered control strategy defines a series of progressively escalating vehicle control instructions to be executed under different conditions such as initial triggering, re-triggering, or continuous violation. The control instructions include multiple levels from low to high, and various instructions can be customized. Levels can be added / deleted, and the trigger conditions, actions, notification methods, and notification recipients for each level can be set. Taking a rental company managing vehicles as an example: the company administrator uses the cloud platform to dynamically create a geofence bound to the rental period for a rental agreement, covering the cities the customer plans to drive in.
[0066] After the hierarchical control strategy is set up, the platform automatically generates a corresponding electronic fence strategy for each selected vehicle and sends the created electronic fence data, bound account ID, control strategy, etc. to the cloud server via the network. The cloud server communicates with the vehicle's vehicle networking module (T-Box) to distribute the data in batches to the target vehicles and store it in the non-volatile memory of the vehicle system.
[0067] Once the corresponding account holder starts the vehicle again or at the time specified in the policy, the designed geofence rules can be applied. Afterward, the administrator can monitor the compliance status of all vehicles in real time on the cloud management platform. If a vehicle triggers the geofence policy, the cloud management platform will issue a centralized alert and generate a report, achieving efficient and unified large-scale fleet management.
[0068] In summary, the vehicle control method offers diverse interaction methods and flexible, convenient management. It supports various interactive terminals, including touchscreens, voice commands, mobile apps, and cloud-based backends, covering all management scenarios from in-vehicle safety operations to remote external management, from manual to voice control, and from single-point to batch strategies, significantly improving user experience and management efficiency. Furthermore, it provides the most intuitive management method: visual map drawing. Administrators can manually and precisely delineate control areas of any shape, offering fine-grained management and a user experience far superior to traditional list-based permission management.
[0069] In one example, generating a prompt message in response to the vehicle's current location exceeding the electronic fence range specifically includes: generating a first prompt message in response to the vehicle's current location exceeding the electronic fence range, the first prompt message being used to notify the driver that the vehicle has exceeded the electronic fence range; generating a second prompt message in response to the vehicle's current location exceeding the electronic fence range by a distance greater than or equal to a second preset distance, and / or the duration of the vehicle exceeding the electronic fence range being greater than or equal to a second preset duration, the second prompt message being used to notify the administrator that the vehicle has exceeded the electronic fence range.
[0070] A first alert is generated when the vehicle's current location exceeds the electronic fence's range. This means that as soon as the vehicle crosses the boundary, a first alert is sent to the driver, allowing them immediate awareness of the violation and sufficient time to adjust their route, preventing escalation of risk or triggering subsequent intervention due to delayed information. Simultaneously, a second alert is sent to the administrator only when the distance or duration of the boundary violation reaches preset thresholds, reducing invalid alarms for minor boundary violations. By combining driver self-correction with administrator supervision and intervention, minor boundary violations rely on driver self-adjustment, while administrator intervention occurs when the risk escalates. This approach reduces management costs while ensuring effective control.
[0071] Optionally, the first prompt message may include, but is not limited to, displaying a red warning icon on the vehicle's instrument panel or HUD, displaying a set prompt message on the central control screen, such as: "You have driven outside the area permitted by the administrator. Please adjust your route." Alternatively, it may play a warning voice prompt, or turn the interior ambient lighting yellow, etc.
[0072] Optionally, the second preset duration is set to 10 minutes. That is, in response to the vehicle exceeding the electronic fence range for a duration of 10 minutes or more, a second prompt message is generated, and the violation event, driving trajectory, operation log, etc., are recorded. The second prompt message is sent to a remote server and administrators with electronic fence management permissions, optionally notifying one or more specific individuals.
[0073] Optionally, the second preset distance is set to 3 kilometers, which refers to the shortest distance between the vehicle's current location and the range of the electronic fence.
[0074] In one example, in response to the vehicle's current location being more than or equal to a first preset distance beyond the electronic fence range, and / or the duration of the vehicle being beyond the electronic fence range being more than or equal to a first preset duration, generating intervention information specifically includes: in response to the vehicle's current location being more than or equal to a first preset distance beyond the electronic fence range, and / or the duration of the vehicle being beyond the electronic fence range being more than or equal to a first preset duration, generating functional restriction information, the functional restriction information being used to restrict at least one of the vehicle's entertainment functions, maximum driving speed, and power output capability; in response to the vehicle's current location being more than or equal to a third preset distance beyond the electronic fence range, and / or the duration of the vehicle being beyond the electronic fence range being more than or equal to a third preset duration, generating intervention control information, the intervention control information being used to control the vehicle to stop and prohibit the vehicle from restarting; the third preset distance is greater than the first preset distance, and the third preset duration is greater than the first preset duration.
[0075] Based on progressively higher thresholds for boundary crossing distance and duration, the system employs a tiered intervention approach, ranging from functional restrictions to mandatory stops. This avoids applying uniformly harsh measures to boundary crossing behaviors of varying risk levels, achieving precise control through escalating risks and intensified interventions. The functional restriction information only limits entertainment functions, maximum speed, or power output, without affecting the vehicle's basic driving capabilities. This serves to remind the driver to correct their route while avoiding driving risks caused by sudden mandatory interventions. The intervention control information targets severe boundary crossing scenarios, minimizing safety hazards to the greatest extent possible.
[0076] Optionally, the first preset duration is set to 20 minutes. That is, in response to the vehicle exceeding the electronic fence range for a duration of 20 minutes or more, functional restriction information is generated. Specifically, the functional restriction information restricts some functions of the vehicle, including but not limited to restricting the use of the in-vehicle entertainment system and limiting the maximum driving speed (the system will generate a CAN message command to limit the vehicle speed). At this time, the remote notification method will also be upgraded, in addition to notifications from apps, SMS notifications can also be selected.
[0077] Optionally, the first preset distance is set to 6 kilometers, which refers to the shortest distance between the vehicle's current location and the range of the electronic fence.
[0078] Optionally, the third preset duration is set to 30 minutes. That is, in response to a vehicle exceeding the electronic fence range for a duration greater than or equal to 30 minutes, intervention control information is generated. This intervention control information allows for proactive intervention on the vehicle, including but not limited to forcing the vehicle to activate its hazard lights, controlling the vehicle to autonomously decelerate and safely park in the nearest safe area, or preventing the vehicle from starting again. All media data will be packaged and uploaded to a cloud server for archiving and evidence retrieval, with a link attached to a notification sent to the administrator. The remote notification method will also be upgraded; in addition to notifications via App and SMS, telephone notifications to administrators with electronic fence management permissions are also possible.
[0079] Optionally, the third preset distance is set to 9 kilometers, and the first preset distance refers to the shortest distance between the vehicle's current location and the range of the electronic fence.
[0080] In one example, the intervention control information is also used to control the operation of the vehicle audio-visual acquisition equipment to collect audio-visual data inside and / or outside the vehicle.
[0081] Collecting audio and video data from inside and outside the vehicle provides a direct basis for subsequent determination of liability for boundary violations and dispute resolution. Furthermore, administrators can use the collected audio and video data to understand the actual situation after a vehicle is forcibly stopped, avoiding delays or misjudgments due to missing information.
[0082] Optionally, the vehicle's built-in dashcam system and in-vehicle camera are forcibly activated through the intervention control information to continuously record audio and video information inside and outside the vehicle in the background. During the recording process, the user inside the vehicle cannot manually turn it off. After recording, specific identifiers and administrators who do not support electronic fence permission management are deleted in the vehicle system. After the vehicle stops, the system automatically controls the surround view camera to take one or more photos of the vehicle's surrounding environment.
[0083] In one example, the method further includes: when generating the prompt information, simultaneously generating first confirmation information, the first confirmation information being used for the driver to confirm whether to request not to execute the electronic fence control strategy, and sending the first confirmation information to the vehicle-side interactive device for the driver to confirm.
[0084] When drivers encounter reasonable boundary violations such as emergency avoidance or temporary task adjustments, they can proactively request that the control policy not be implemented, avoiding the inconvenience caused by a one-size-fits-all approach. This setting reduces ineffective control and disputes, allows drivers to proactively confirm exceptions, helps administrators quickly distinguish between malicious boundary violations and reasonable exemptions, and reduces user complaints and management costs caused by unreasonable intervention. Furthermore, it better adapts to diverse special scenarios, covering unconventional situations such as emergency medical care, temporary route changes, and responses to sudden road conditions.
[0085] In one example, the method further includes: in response to a driver's confirmation request not to execute the electronic fence control policy, generating a second confirmation message, the second confirmation message being used by an administrator to confirm whether to execute the electronic fence control policy, and sending the second confirmation message to an interactive terminal for the administrator to confirm.
[0086] Administrators can receive a second confirmation message from drivers requesting that the electronic fence control policy not be implemented. By combining real-time traffic conditions, task requirements, driver qualifications, and other information, administrators can make a comprehensive judgment, review and approve reasonable requests such as emergency avoidance, and promptly reject illegal requests, thus achieving flexible management and control.
[0087] Optionally, after receiving the second confirmation message on the mobile terminal or cloud management platform, the administrator can review it as "pass / fail". If the review is passed, the vehicle geofence policy for this account will not be implemented temporarily; otherwise, it will be implemented as usual. Furthermore, for complete modifications, an administrator with geofence management permissions must modify or delete the geofence range and hierarchical control policy at least one of the following: vehicle-side interactive device, cloud management platform, or mobile terminal.
[0088] In summary, the vehicle control method provided in this application introduces a progressive, tiered response mechanism, ranging from mild warnings to mandatory intervention. This ensures safety while minimizing overreaction, achieving intelligent risk management. Furthermore, the permission policy is triggered by the vehicle's geographical location and duration, eliminating the need for real-time administrator monitoring and significantly improving management efficiency and security. A cloud-based remote notification channel is also established, ensuring administrators can immediately detect abnormal vehicle conditions, greatly enhancing vehicle asset security and management timeliness. Moreover, it perfectly adapts to various scenarios, allowing for the setting of safe driving routes for family accounts, the creation of electronic fences to prevent vehicle theft for rental vehicles, and even the setting of business areas for corporate fleets to ensure shared use of vehicles. Electronic fence policies can be set, updated, or revoked anytime, anywhere, individually or in batches for any vehicle, enabling truly refined asset management and effectively protecting vehicle asset security and user behavior safety.
