[0061] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for which protection is claimed, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, each other embodiment obtained by those skilled in the art without making creative work falls within the scope of protection of the present application.

[0062] Existing technology uses GPS to track a vehicle's real-time location, integrated with a geographic information system (GIS) for precise boundary detection. Vehicle owners can remotely monitor and control their vehicles through a mobile app or website, such as locking / unlocking the vehicle, setting fenced areas, and viewing the vehicle's location. The system monitors the vehicle's location in real time and immediately notifies the owner of any anomalies, enhancing vehicle safety. This system can be used not only for personal vehicles but also for fleet management, rental vehicle monitoring, and other fields.

[0063] However, existing technologies may have some limitations, such as performance degradation in poor signal environments, inability to accurately determine the vehicle's current location and whether it is within a preset area, and the electronic fence set for vehicles by existing methods is generally a fixed-size area, which limits its adaptability.

[0064] Based on this, the embodiments of the present application provide a method and device for determining a vehicle's electronic fence, which can perform precise positioning even when the communication status is poor, and dynamically adjust the vehicle's electronic fence to better adapt to different speeds and environmental changes, thereby improving vehicle safety.

[0065] See also Figure 1 , Figure 1 This is a flow chart of a method for determining a vehicle electronic fence provided in an embodiment of the present application. Figure 1 As shown in , the determination method provided in the embodiment of the present application includes:

[0066] S101: Determine whether the current actual position of the target vehicle can be obtained.

[0067] S102: If the target vehicle cannot be obtained, determine the current predicted position of the target vehicle based on the historical driving data of the target vehicle, and establish a vehicle local coordinate system based on the current predicted position.

[0068] S103 , dividing the fence in the vehicle local coordinate system according to a preset electronic fence division rule, and determining a temporary electronic fence for the target vehicle.

[0069] S104: Update the boundary of the temporary electronic fence according to the target obstacles in the environment surrounding the target vehicle to obtain the target electronic fence of the target vehicle.

[0070] The following describes the exemplary steps of the embodiment of the present application:

[0071] Regarding step S101, this step may specifically include determining whether the current actual position of the target vehicle can be obtained according to the network communication status.

[0072] For example, when the network or GPS signal is abnormal, it is determined that the current actual position of the target vehicle cannot be obtained.

[0073] In one embodiment provided in the present application, before determining whether the current actual position of the target vehicle can be obtained, the determination method further includes:

[0074] S201: Determine whether the electronic fence function of the target vehicle is turned on.

[0075] S202: If it is enabled, identify whether the network communication for determining the current actual position of the target vehicle is normal.

[0076] S203: If normal, determine that the current actual position of the target vehicle can be obtained;

[0077] S204: If abnormal, determine that the current actual position of the target vehicle cannot be obtained.

[0078] Regarding step S201, when determining whether the electronic fence function of the target vehicle is turned on, it can be determined based on whether there is an opening mark. For example, the opening of the electronic fence function can be determined by a control in the APP on the smart terminal.

[0079] Here, if it is determined that the electronic fence function of the target vehicle has been turned on, step S202 is executed, otherwise the process ends.

[0080] For step S202, in this step, when it is determined that the electronic fence function of the target vehicle has been turned on, the network communication used to determine the current actual position of the target vehicle is identified, and it is determined that the network communication identification is normal. If normal, step S203 is executed; if abnormal, step S204 is executed.

[0081] That is, step S102 is executed immediately after step S204 is executed.

[0082] Regarding step S102, in this step, after determining that the current actual position of the target vehicle cannot be obtained, the historical driving data of the target vehicle within a certain period of time before the current moment is obtained; based on the historical driving data and the position prediction process, the current position of the target vehicle is predicted to determine the current predicted position of the target vehicle; finally, based on the current predicted position of the target vehicle and combined with the current driving data, a vehicle local coordinate system is established.

[0083] Here, the historical driving data may include relevant data such as the target vehicle's historical driving speed, driving direction, driving acceleration, etc. The determined current predicted position of the target vehicle may specifically be the position of the target vehicle's rear axle center.

[0084] When establishing the local coordinate system of the vehicle, the center position of the rear axle of the vehicle (the current predicted position) can be used as the origin and the driving direction as the Y axis to establish the local coordinate system of the vehicle.

[0085] In step S103, the size and shape of the electronic fence, as well as the rules for dividing the electronic fence according to different driving data, are determined based on the preset electronic fence division rules. Then, the fence is divided in the vehicle local coordinate system based on the determined size and shape of the electronic fence and the driving data of the target vehicle, thereby obtaining a temporary electronic fence for the target vehicle. At this point, the target vehicle is located within the resulting temporary electronic fence.

[0086] Here, when the position of the target vehicle changes, the position area of the temporary electronic fence also changes accordingly.

[0087] Regarding step S104, this step includes updating the boundary of the temporary electronic fence according to the position information of the target obstacle in the surrounding environment of the target vehicle to obtain the target electronic fence of the target vehicle.

[0088] In one embodiment provided by the present application, updating the boundary of the temporary electronic fence according to the target obstacle in the surrounding environment of the target vehicle to obtain the target electronic fence of the target vehicle includes:

[0089] S1041. Collect environmental data around the target vehicle to determine whether there are obstacles that affect the driving of the target vehicle.

[0090] S1042: If so, the obstacle located inside the temporary electronic fence or overlapping with the boundary of the temporary electronic fence is identified and determined as a target obstacle.

[0091] S1043: Update the boundary of the temporary electronic fence according to the location information and size information of the target obstacle to obtain the target electronic fence of the target vehicle.

[0092] Regarding step S1041, this step may specifically include: monitoring the environment around the target vehicle according to the environment acquisition device (such as laser, radar, stereo vision device, etc.) on the target vehicle to obtain environmental data; then analyzing the obtained environmental data to determine whether there are obstacles that affect the driving of the target vehicle.

[0093] If it exists, step S1042 is executed; if it does not exist, the temporary electronic fence is determined as the target electronic fence.

[0094] Regarding step S1042, in this step, after it is determined that there are obstacles that affect the travel of the target vehicle, the size and position of each obstacle are determined, and obstacles located inside the temporary electronic fence or overlapping with the boundary of the temporary electronic fence are determined as target obstacles.

[0095] Here, when determining the size and position of each obstacle, specifically, the size and position of each obstacle in the vehicle local coordinate system are determined.

[0096] With respect to step S1043 , the boundary of the temporary electronic fence is re-divided according to the position information and size information of the target obstacle to obtain the target electronic fence of the target vehicle.

[0097] Among them, when the vehicle is traveling, the position of the target electronic fence can also be updated in real time and then updated periodically.

[0098] For examples, see Figure 2 , Figure 2 This is a schematic diagram of the principle of updating an electronic fence provided by this application. Figure 2 As shown, the original rectangular frame area is a temporary electronic fence. When the target obstacle is determined to exist, the obstacle is removed and a new boundary line is determined. The area after the removal is the target electronic fence. Here, the boundary of the temporary electronic fence is updated at the same time as the removal.

[0099] Furthermore, in an embodiment provided in the present application, if it is determined that the current actual position of the target vehicle can be obtained, the determination method further includes:

[0100] S301: Acquire the current actual position and related motion data of the target vehicle.

[0101] S302: Determine a temporary electronic fence for the target vehicle by dividing the fence according to the current actual position of the target vehicle, relevant motion data, and preset electronic fence division rules.

[0102] S303: Update the boundary of the temporary electronic fence according to the target obstacles in the environment surrounding the target vehicle to obtain the target electronic fence of the target vehicle.

[0103] Regarding step S301, this step includes obtaining the current actual position and related motion data of the target vehicle based on a network signal or a GPS signal.

[0104] Here, the relevant motion data may include current driving speed, driving direction, driving angle, etc.

[0105] Regarding step S302, in this step, the method of determining the temporary electronic fence is similar to that of step S104, and will not be repeated here.

[0106] The description of S303 may refer to the description of S104 and can achieve the same technical effect, so it will not be described in detail.

[0107] Furthermore, in another embodiment provided in the present application, after obtaining the target electronic fence of the target vehicle, the determination method also includes: determining whether the target vehicle is located inside the target electronic fence based on the current position and size information of the target vehicle; if not, issuing an out-of-bounds prompt; if it is determined that the target vehicle is located inside the target electronic fence, returning to continue executing the identification to determine whether the network communication used to determine the current actual position of the target vehicle is normal.

[0108] Here, the current position is the current actual position or the current predicted position.

[0109] Returning to continue to identify whether the network communication for determining the current actual position of the target vehicle is normal is to continue to determine the update of the electronic fence.

[0110] Furthermore, when providing a boundary-crossing prompt, the system may specifically include: controlling the vehicle's internal audio playback device to play a boundary-crossing prompt, and / or controlling the vehicle's internal video device to display a boundary-crossing prompt, and / or sending the boundary-crossing prompt to the target user's smart device. The internal video device may be, for example, a central control screen.

[0111] Thus, through multi-sensor data fusion, this application maintains high-precision positioning even in environments with poor network communication conditions, allowing vehicles to remain effectively monitored. Furthermore, the electronic fence in this application can adjust the fence size in real time to better adapt to different speeds and environmental changes, improving vehicle safety. It also responds to changes in vehicle position in real time, updating the fence boundaries in a timely manner, further reducing safety risks. Therefore, this solution enables real-time monitoring of vehicles and adaptive adjustment of boundaries, ensuring vehicle safety even in the presence of poor GPS signals.

[0112] Based on the same inventive concept, the embodiments of the present application also provide a determination device corresponding to the determination method. Since the principle of solving the problem by the device in the embodiments of the present application is similar to the above-mentioned determination method in the embodiments of the present application, the implementation of the device can refer to the implementation of the method, and the repeated parts will not be repeated.
