[0033] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0037] Before introducing the specific implementation methods of the present disclosure in detail, the application scenarios of the present disclosure are first described as follows. The present disclosure can be applied to the application scenario of recommending charging stations for vehicles when the vehicle is traveling on a highway. During highway driving, the charging piles in some highway service areas are overloaded, have equipment failures, or are undergoing maintenance. However, the existing technology is often unable to obtain and analyze the status of charging resources in the opposite service area, making it difficult for users to make reasonable judgments. For example, when the charging resources in the service area on this side are tight, the driver may not know whether the opposite service area has available charging resources, nor can he confirm whether he can go to the opposite service area to charge, thus falling into a state of "battery anxiety", which not only reduces the user's travel efficiency, but also seriously affects the driving experience.

[0038] Figure 1 is a flowchart of a method for updating navigation data according to an exemplary embodiment. Figure 1 As shown, the following steps may be included.

[0039] Step 101: Obtain navigation data.

[0040] The navigation data is used to indicate the driving route of the vehicle. For example, the navigation data may be GPS (Global Positioning System) data or Beidou satellite positioning data.

[0041] Step 102: When the vehicle enters a preset area, information about charging equipment in the preset area is obtained.

[0042] The preset area may be an area including a highway section.

[0043] Step 103: When there is no available charging equipment in the current driving direction of the vehicle, obtain the charging equipment information in the opposite direction of the current driving direction of the vehicle.

[0044] The charging equipment information is used to indicate whether there is an available charging equipment in the current driving direction of the vehicle.

[0045] Step 104 : When there is available charging equipment in the opposite direction of the vehicle's current travel, update the navigation data.

[0046] In this step, updating the navigation data includes: determining a target charging device from the available charging devices, and updating the navigation data based on the target charging device.

[0047] The above technical solution obtains information about charging facilities within a preset area when the vehicle enters the area; obtains information about charging facilities in the opposite direction of the vehicle's current travel if no charging facilities are available in the vehicle's current direction; and updates navigation data if charging facilities are available in the opposite direction of the vehicle's current travel. When a user needs to charge, the system can accurately identify or recommend nearby available charging facilities and promptly update navigation data, effectively improving travel efficiency and driving experience.

[0048] Figure 2 is based on Figure 1 The embodiment shown is a flowchart of a method for updating navigation data, as shown in FIG. Figure 2 As shown, in Figure 1 The updating of the navigation data in step 104 may include: Step 201: Display an update prompt message.

[0049] The update prompt message is used to prompt the user to update the navigation data.

[0050] Step 202: In response to receiving a target operation in response to the update prompt message, update the navigation data.

[0051] The target operation may be an interactive behavior performed by the user on the vehicle terminal interface on the update prompt information, including but not limited to a click operation and a slide operation.

[0052] In this step, the displaying of the update prompt message includes at least one of the following methods: displaying an update prompt window through a display device, the update prompt window including the update prompt message; and outputting the update prompt message through a voice device.

[0053] For example, an update prompt window could pop up on the vehicle's display (central control screen or instrument panel). This prompt window contains update controls (confirm and cancel buttons) and information about the update (for example, "If a charging device is available, do you want to update the navigation data immediately?"). The user can click the "Confirm" button to trigger the update operation and update the navigation data. In driving scenarios, the simple button design facilitates quick operation and avoids distraction, thereby effectively improving driving safety.

[0054] As another example, an update prompt window could pop up on the vehicle's display (central control screen or instrument panel). This prompt window contains a slider control (slider bar or slider button) and information about the update (for example, "A charging device has been found. Do you want to update the navigation data immediately?"). The user can trigger the update operation by sliding the slider control from left to right, thereby updating the navigation data. In driving scenarios, sliding confirmation requires a clearer user intent, thereby effectively reducing accidental operations.

[0055] As another example, if the vehicle's equipment supports voice notifications (such as smart speakers or voice assistants), it can notify the user of available charging equipment through voice notification and ask the user whether to update the navigation data immediately (for example: Hello, I found an available charging equipment nearby. Do you want to update the navigation data immediately?). The user can respond with "Agree," "Yes," or "OK" to trigger the update operation and update the navigation data. During driving, receiving information through voice prompts instead of needing to check the screen can reduce driver distraction and effectively improve driving safety.

[0056] The above technical solution updates the navigation data by displaying an update prompt message and in response to receiving a target operation on the update prompt message. It can update the navigation data with the user's consent, thereby providing the user with appropriate charging equipment in a timely manner, thereby effectively improving the user's travel efficiency.

[0057] Optionally, the method may further include: Display update suggestion message.

[0058] The update suggestion message is used to suggest whether to update the navigation data.

[0059] In this step, the update suggestion message is determined by at least one of the following information: the current remaining power of the vehicle; the charging equipment information of the specified preset area, the specified preset area including the next preset area of ​​the preset area in the current driving direction; the user's charging preference information, the charging preference information is used to indicate whether the user prefers to use the available charging equipment in the opposite direction of the vehicle's current travel for charging.

[0060] In one embodiment, the update suggestion message is determined according to the current remaining power of the vehicle.

[0061] In this step, when it is determined that the current remaining power of the vehicle is less than or equal to a preset power threshold, the update suggestion message is determined to be a suggestion to update the navigation data.

[0062] For example, the preset power threshold is 30%, and the current remaining power is 28%. It is determined that the current remaining power of the vehicle is less than the preset power threshold, and the update suggestion message is determined to be: "The current power is low, it is recommended to update the navigation data immediately and go to the nearest charging device to charge."

[0063] In another embodiment, the update suggestion message is determined based on charging equipment information of a specified preset area.

[0064] The designated preset area may be the next preset area in the current driving direction. For example, if the current preset area is the first service area on the vehicle's driving route on a highway, the designated preset area may be the second service area on the vehicle's driving route.

[0065] In this step, when it is determined based on the charging equipment information of the next preset area in the current driving direction that no available charging equipment exists in the next preset area in the current driving direction, the update suggestion message is determined to be a suggestion to update the navigation data.

[0066] For example, the charging equipment information of the next preset area in the current driving direction indicates that there is no available charging equipment, it is determined that there is no available charging equipment in the specified preset area, and the update suggestion message is determined to be: "There is no available charging equipment in the specified area, it is recommended to update the navigation data immediately and go to the nearest charging equipment for charging."

[0067] In yet another embodiment, the update suggestion message is determined according to the user's charging preference information.

[0068] In this step, when it is determined that the charging preference information is a preference for using a charging device in the opposite direction of the vehicle's current travel, the update suggestion message is determined to be a suggestion to update the navigation data.

[0069] For example, when it is determined that the charging preference information is a preference for using the charging equipment in the opposite direction of the vehicle's current travel, the update suggestion message is determined to be: "There is an available charging equipment in the opposite direction of the vehicle's current travel. It is recommended to update the navigation data immediately and go to the nearest charging equipment to charge."

[0070] The charging preference information may be determined based on the vehicle's historical charging data, which includes multiple charging events, each of which includes a charging location and the vehicle's route before reaching the charging station.

[0071] For each charging event, the charging station's location relative to the vehicle's previous route to the charging station is determined. A charging event in which the vehicle is charged by a charging device in the opposite direction of the vehicle's current travel is designated as a target charging event. If the target charging event is determined to have occurred more than or equal to a preset threshold number of times in the historical charging data, the charging preference information is determined to favor the use of charging devices in the opposite direction of the vehicle's current travel.

[0072] In some embodiments, the update suggestion message may also be determined by combining two pieces of information: the current remaining power of the vehicle, the charging equipment information of a specified preset area, and the user's charging preference information.

[0073] In one embodiment, the update suggestion message is determined based on the current remaining power of the vehicle and charging equipment information in a designated preset area.

[0074] In this step, when it is determined that the current remaining power of the vehicle is less than or equal to the preset power threshold and the charging equipment information of the specified preset area does not contain any available charging equipment, the update suggestion message is determined to be a suggestion to update the navigation data.

[0075] For example, the current remaining power is 28% and the power threshold is 30%. It can be determined that the current remaining power of the vehicle is less than the preset power threshold. If it is determined that there is no available charging equipment in the charging equipment information of the specified preset area, the update suggestion message is determined to be: "The current power is low and there is no available charging equipment in the specified area. It is recommended to update the navigation data immediately and go to the nearest charging equipment to charge."

[0076] In another embodiment, the update suggestion message is determined based on the current remaining power of the vehicle and the user's charging preference information.

[0077] In this step, when it is determined that the current remaining power of the vehicle is less than or equal to the preset power threshold and the charging preference information is a preference to use the charging equipment in the opposite direction of the vehicle's current travel, the update suggestion message is determined to be a suggestion to update the navigation data.

[0078] For example, if the current remaining battery charge is 30% and the battery charge threshold is 30%, and the vehicle's current remaining battery charge is determined to be equal to the battery charge threshold, and if the charging preference information indicates a preference for charging equipment in the direction opposite to the vehicle's current travel, the update suggestion message may be: "The current battery charge is low, and there is an available charging equipment in the direction opposite to the vehicle's current travel. It is recommended that you update your navigation data immediately and proceed to the nearest charging equipment for charging." If the vehicle's current remaining battery charge is determined to be greater than the preset battery charge threshold, and the charging preference information indicates a preference for charging equipment in the direction of the vehicle's current travel, the update suggestion message may not be displayed.

[0079] In yet another embodiment, the update suggestion message is determined based on charging equipment information of a designated preset area and charging preference information of the user.

[0080] In this step, when it is determined that there is no available charging equipment in the charging equipment information of the specified preset area and the charging preference information is to prefer using the charging equipment in the opposite direction of the vehicle's current travel, the update suggestion message is determined to be a suggestion to update the navigation data.

[0081] For example, when it is determined that there is no available charging equipment in the charging equipment information of the specified preset area, and the charging preference information is to prefer to use the charging equipment in the opposite direction of the vehicle's current travel, the update suggestion message is determined to be: "There is no available charging equipment in the specified area, and there is an available charging equipment in the opposite direction of the vehicle's current travel. It is recommended to update the navigation data immediately and go to the nearest charging equipment for charging."

[0082] The above technical solution determines the update suggestion message based on at least two pieces of information including the current remaining power of the vehicle, the charging equipment information of the specified preset area, and the user's charging preference information. It can comprehensively consider the actual status of the vehicle and personalized needs, making the update suggestion message more comprehensive and thus more in line with the user's actual usage scenarios and needs.

[0083] In some embodiments, the update suggestion message may also be determined in combination with the current remaining power of the vehicle, the charging equipment information of a designated preset area, and the user's charging preference information.

[0084] In this step, if it is determined that the vehicle's current remaining battery charge is less than or equal to a preset battery charge threshold, the charging equipment information in the designated preset area does not contain any available charging equipment, and the charging preference information indicates a preference for using charging equipment in the direction opposite to the vehicle's current travel, the update suggestion message is determined to be a suggestion to update navigation data. If it is determined that the vehicle's current remaining battery charge is greater than the preset battery charge threshold, the charging equipment information in the designated preset area does contain any available charging equipment, and the charging preference information indicates a preference for not using charging equipment in the direction opposite to the vehicle's current travel, the update suggestion message is not displayed.

[0085] For example, the current remaining power is 30%, and the power threshold is 30%. It is determined that the current remaining power of the vehicle is less than the power threshold. If the charging equipment information of the specified preset area does not contain any available charging equipment, and the charging preference information is to prefer to use the charging equipment in the opposite direction of the vehicle's current travel, the update suggestion message is determined to be: "There is no available charging equipment in the specified area, and there is an available charging equipment in the opposite direction of the vehicle's current travel. It is recommended to update the navigation data immediately and go to the nearest charging equipment to charge."

[0086] The above technical solution provides the user with an update suggestion message before updating the navigation data, so that the user can determine whether the navigation data needs to be updated based on the update suggestion message before updating the navigation data, thereby effectively improving travel efficiency and travel experience.

[0087] Figure 3 is based on Figure 1 The embodiment shown is a flowchart of a method for updating navigation data, as shown in FIG. Figure 3 As shown, in Figure 1 The updating of the navigation data in step 104 may include: Step 301: Determine a target charging device from the available charging devices.

[0088] In one embodiment, determining a target charging device from the available charging devices may include: using the available charging device closest to a designated location in a charging area as the target charging device, where the charging area is the area where the available charging device is located, and the designated location includes an entrance or exit of the charging area.

[0089] For example, the predefined areas include a first charging area and a second charging area, where the first charging area is the charging area in the vehicle's current direction of travel. The second charging area is the charging area in the opposite direction of travel. If no charging equipment is available in the first charging area, at least one available charging equipment is identified from the second charging area. The available charging equipment closest to the entrance of the second charging area can be used as the target charging equipment. This reduces the number of driving routes into the second charging area to find the target charging equipment, avoiding detours and thus saving time and vehicle energy. Alternatively, the available charging equipment closest to the exit of the second charging area can be used as the target charging equipment. This reduces the number of driving routes out of the second charging area, which is particularly useful during peak hours and effectively improves traffic efficiency. For example, the first charging area can be a service area on the opposite side of a highway section that is in the same direction as the vehicle's current travel, while the second charging area can be a service area on the opposite side of a highway section that is in the opposite direction of travel.

[0090] In another embodiment, the preset area includes multiple charging areas, and the available charging devices are located in different charging areas; determining the target charging device from the available charging devices may include: taking the available charging device closest to a designated position of the charging area among the available charging devices in each charging area as a candidate charging device; the designated position includes an entrance or exit of the charging area; obtaining the driving distance between the candidate charging device and the vehicle; and taking the candidate charging device with the shortest driving distance as the target charging device.

[0091] For example, the preset areas may include a first charging area, a second charging area, and a third charging area on a highway section. The first charging area may be a charging area in the vehicle's current direction of travel. The second charging area may be a charging area in the opposite direction of travel. The third charging area may be the previous charging area in the opposite direction of travel, or the previous charging area in the opposite direction of travel. For example, the first charging area may be a service area in a service area on the highway section that is in the same direction as the vehicle's current travel, the second charging area may be a service area in a service area on the highway section that is in the opposite direction of travel. The third charging area may be the previous service area in the same direction as the vehicle's current travel, or the previous service area in a service area on the highway section that is in the opposite direction of travel.

[0092] The available charging device closest to the entrance of the first charging area among the available charging devices in the first charging area is selected as a candidate charging device. The available charging device closest to the entrance of the second charging area among the available charging devices in the second charging area is selected as a candidate charging device. The available charging device closest to the entrance of the third charging area among the available charging devices in the third charging area is selected as a candidate charging device. The driving distance between each candidate charging device and the vehicle is obtained, and the candidate charging device with the shortest driving distance is selected as the target charging device. By selecting the available charging device closest to the entrance of each charging area among the available charging devices in the charging area as a candidate charging device and selecting the candidate charging device with the shortest driving distance as the target charging device, the driving path for entering the charging area to search for the target charging device can be reduced, detours can be avoided, and time and vehicle power can be saved.

[0093] The available charging device closest to the exit of the first charging area among the available charging devices in the first charging area is selected as a candidate charging device. The available charging device closest to the exit of the second charging area among the available charging devices in the second charging area is selected as a candidate charging device. The available charging device closest to the exit of the third charging area among the available charging devices in the third charging area is selected as a candidate charging device. The driving distance between each candidate charging device and the vehicle is obtained, and the candidate charging device with the shortest driving distance is selected as the target charging device. By selecting the available charging device closest to the exit of each charging area among the available charging devices in the charging area as a candidate charging device and selecting the candidate charging device with the shortest driving distance as the target charging device, the driving path out of the charging area can be reduced, which is particularly suitable for peak hours, thereby effectively improving traffic efficiency.

[0094] Step 302: Update the navigation data based on the target charging device.

[0095] In this step, the driving trajectory between the vehicle position and the device position of the target charging device is used as the updated navigation data.

[0096] The above technical solution determines the target charging device from the available charging devices; and based on the target charging device, updates the navigation data, can accurately identify or recommend nearby available charging devices, and timely update the navigation data, thereby effectively improving the user's travel efficiency and driving experience.

[0097] In one possible implementation, Figure 3 In step 301, determining a target charging device from the available charging devices may include: The available charging device closest to the designated location in the charging area is used as the target charging device.

[0098] The charging area is the area where the available charging equipment is located. The designated location includes the entrance or exit of the charging area.

[0099] In this step, the preset area includes a first charging service area and a second charging service area, wherein the first charging service area is the charging service area in the current driving direction of the vehicle. The second charging service area is the charging service area in the opposite direction of the current driving direction of the vehicle. When it is determined that there is no available charging equipment in the first charging service area, at least one available charging equipment is determined from the second charging service area. The available charging equipment closest to the entrance of the second charging service area can be used as the target charging equipment. By reducing the driving path into the second charging service area to search for the target charging equipment, detours can be avoided, thereby saving time and vehicle power. The available charging equipment closest to the exit of the second charging service area can also be used as the target charging equipment. By reducing the driving path out of the second charging service area, it is particularly suitable for peak hours and can effectively improve traffic efficiency.

The driving distance between each candidate charging device and the vehicle is obtained, and the candidate charging device with the shortest driving distance is selected as the target charging device. By selecting the available charging device closest to the exit of each charging area among the available charging devices in the charging area as a candidate charging device and selecting the candidate charging device with the shortest driving distance as the target charging device, the driving path leaving the charging service area can be reduced, which is particularly suitable for peak hours, thereby effectively improving traffic efficiency.

[0108] It should be noted that before determining to obtain the charging equipment information in the opposite direction of the vehicle's current travel, it is determined that there are passages between the multiple charging areas in the preset area.

[0109] The above technical solution selects the available charging device closest to the designated location of each charging area as the candidate charging device, and selects the candidate charging device with the shortest driving distance as the target charging device, which can provide users with the nearest charging device, thereby effectively improving travel efficiency and travel experience.
