Description

Technical Field

[0001] This invention relates to the field of electric vehicle navigation technology, and in particular to a vehicle navigation intelligent planning method, system and electronic device. Background Technology

[0002] With societal progress and the continuous improvement of people's living standards, new energy vehicles (electric vehicles) have gradually integrated into people's lives, becoming an indispensable means of transportation. Many new energy vehicle owners now experience increasing anxiety as their driving range gradually decreases, worrying about when and where to charge. On highways, the range reduction is even more pronounced, leaving drivers uncertain about the actual remaining range. Missing a service area could mean not reaching the next one.

[0003] However, by dynamically calculating and recommending charging locations in real time during navigation, drivers can be informed, reducing charging anxiety and preventing situations where there are no available charging stations when users arrive at their navigation destination. This can lead to insufficient battery power in new energy vehicles or increased charging waiting time, thereby reducing the user experience of new energy vehicles. Summary of the Invention

[0004] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0005] In view of the shortcomings of the prior art described above, this application provides a vehicle navigation intelligent planning method, system and electronic device to solve the problem that a vehicle cannot find a charging pile when navigating to a target charging station.

[0006] The first aspect of this application provides a vehicle navigation intelligent planning method, comprising: acquiring a navigation target of a target vehicle, wherein the target vehicle is at least one of electric vehicles; if the type of the navigation target is a charging station, determining the intention of the target vehicle to park at the charging station; if the intention includes first intention information and the number of charging piles at the charging station is detected to be less than a first preset number, then maintaining the navigation path without reminding the driver, wherein the first intention information includes not charging or waiting to charge; if the intention includes second intention information and the number of charging piles at the charging station is detected to be less than a first preset number, then planning based on the current location information and driving range of the target vehicle to generate a backup charging scheme, wherein the second intention information includes charging immediately; responding to a first voice command, displaying the backup charging scheme and performing voice broadcast; responding to a second voice command, selecting a backup charging station in the backup charging scheme to switch the navigation target to the backup charging station for navigation.

[0007] In some possible embodiments of this application, before detecting that the number of charging piles at the charging station is lower than a first preset number, the method further includes: acquiring the current location information, driving range, and average power consumption of the target vehicle; calculating the remaining distance between the current location information of the target vehicle and the navigation target; estimating the remaining battery power of the target vehicle to reach the navigation target based on the remaining distance, the driving range, and the average power consumption; if the remaining battery power is lower than a preset battery power threshold, then detecting the number of charging piles at the charging station; if the remaining battery power is higher than or equal to the preset battery power threshold, then not detecting the number of charging piles at the charging station.

[0008] In some possible embodiments of this application, the remaining battery power of the target vehicle to reach the navigation target is estimated based on the remaining distance, the driving range, and the average power consumption. The estimated power consumption required for the target vehicle to reach the navigation target is calculated based on the remaining distance and the average power consumption. If the driving range is greater than the remaining distance, the difference between the SOC value of the driving range and the estimated power consumption is calculated to determine the remaining battery power of the target vehicle to reach the navigation target.

[0009] In some possible embodiments of this application, a backup charging plan is generated based on the current location information and remaining range of the target vehicle. This includes: obtaining the type of charging pile required for charging the target vehicle, wherein the charging pile type includes at least one of slow charging, fast charging, and supercharging; comparing the current remaining distance of the target vehicle with the remaining range; if the remaining range is less than or equal to the remaining distance, then using a preset proportion of the remaining range as a filtering range, selecting a backup charging station close to the navigation target, and generating a backup charging plan based on the charging pile type of the target vehicle; if the remaining range is greater than the remaining distance, and the remaining battery power is lower than a preset battery power threshold, then using the navigation target as a filtering range, selecting a backup charging station close to the navigation target and matching the charging pile type of the target vehicle, and generating a backup charging plan. Each backup charging plan includes the total number of charging piles, the remaining number, and the distance from the navigation target.

[0010] In some possible embodiments of this application, a backup charging scheme is generated based on the current location information and driving range of the target vehicle. This includes: obtaining the type of charging pile required for charging the target vehicle, wherein the charging pile type includes at least one of slow charging, fast charging, and supercharging; dynamically calculating the charging time and charging pile location based on the driving range and the number and availability of charging piles at the backup charging station; and selecting charging piles that match the charging pile type with the shortest charging time as the target, thereby determining a backup charging scheme that includes the location of the target charging pile.

[0011] In some possible embodiments of this application, after determining the backup charging scheme including the location of the target charging pile, the method further includes: formulating a first navigation route and a second navigation route to reach the location of the target charging pile; wherein, the first navigation route is a navigation route to reach the target charging pile location in the service area; and the second navigation route is a navigation route to reach the target charging pile location outside the service area.

[0012] In some possible embodiments of this application, in response to a first voice command, the backup charging solution is displayed and voice broadcast is performed; in response to a second voice command, a backup charging station in the backup charging solution is selected, including: if the first voice command received includes a switching command, the travel time required for the target vehicle to reach each backup charging station in the backup charging solution is calculated, the total time for each path is determined based on the charging time and the travel time, and the backup charging solutions are displayed in the navigation system and voice broadcast according to the total time; if the second voice command received includes any path selection command, a backup charging station in the backup charging solution is selected according to any path selection command, so that the navigation target switches to the backup charging station corresponding to any path selection command for navigation.

[0013] In some possible embodiments of this application, before receiving the second voice instruction including any route selection instruction, the method further includes: calculating the charging cost of the target vehicle on each route according to the billing method of each backup charging station, sorting them according to the total time, and simultaneously displaying the charging cost between each backup charging scheme in the navigation system, and broadcasting the displayed backup charging scheme by voice.

[0014] A second aspect of this application also provides a vehicle navigation intelligent planning system, comprising: an acquisition module for acquiring a navigation target of a target vehicle, wherein the target vehicle is at least one of electric vehicles; an intent determination module for determining, if the type of the navigation target is a charging station, the intent of the target vehicle to park at the charging station; a navigation monitoring module for maintaining the navigation path and not reminding the driver if the intent includes first intent information and the number of charging piles at the charging station is detected to be less than a first preset number, wherein the first intent information includes not charging or waiting to charge; a scheme planning module for generating an alternative charging scheme based on the current location information and driving range of the target vehicle if the intent includes second intent information and the number of charging piles at the charging station is detected to be less than a first preset number, wherein the second intent information includes charging immediately; and a route switching module for displaying the alternative charging scheme and providing voice broadcast in response to a first voice command, and selecting an alternative charging station in the alternative charging scheme in response to a second voice command, so that the navigation target switches to the alternative charging station for navigation.

[0015] A third aspect of this application also provides an electronic device, comprising: a processor and a memory; the memory for storing a computer program, and the processor for executing the computer program stored in the memory to cause the electronic device to perform the methods described above.

[0016] The beneficial effects of this application are as follows: This application obtains the navigation target of the target vehicle. If the type of the navigation target is a charging station, it determines the intention of the target vehicle to park at the charging station, thereby improving the navigation experience through intention recognition. If the intention includes first intention information and the number of charging piles at the charging station is detected to be lower than a first preset number, the navigation path is maintained without reminding the driver, avoiding unnecessary interference. If the intention includes second intention information and the number of charging piles at the charging station is detected to be lower than a first preset number, a backup charging plan is generated based on the target vehicle's current location information and remaining range. In this way, through dynamic resource monitoring and decision optimization, the charging efficiency is effectively improved. Convenience and efficiency: Responding to a first voice command, the system displays and announces the backup charging plan; responding to a second voice command, it selects a backup charging station from the backup charging plan, allowing the navigation target to switch to the backup charging station for navigation. On one hand, selecting a backup charging station according to user needs enables rapid switching of the navigation target. The voice interaction method simplifies the operation process, prevents accidental operation while driving, and improves driving safety. On the other hand, by planning backup charging plans in advance, it ensures that the vehicle can reach a suitable charging station before the battery runs out, avoiding driving interruptions due to insufficient power and improving the energy efficiency and driving safety of electric vehicles.

[0024] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the invention. However, it will be apparent to those skilled in the art that embodiments of the invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the invention.

It should be understood that such data can be interchanged where appropriate for the embodiments of this disclosure described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0028] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0029] Combination Figure 1 As shown in the figure, this disclosure provides a flowchart of a vehicle navigation intelligent planning method, including:

[0030] Step S101: Obtain the navigation target of the target vehicle, wherein the target vehicle is at least one of electric vehicles;

[0031] It should be understood that the electric vehicle refers to a vehicle powered by an onboard power source, including but not limited to pure electric vehicles, plug-in hybrid electric vehicles, and range-extended hybrid electric vehicles. The navigation target refers to the navigation destination input by the user.

[0032] For example, after a user gets into the car, they turn on the vehicle's built-in navigation system and enter "Chongqing Jiefangbei" into the navigation system. At this time, the navigation target "Chongqing Jiefangbei" is the destination location with the current location as the starting point.

[0033] Step S102: If the type of the navigation target is a charging station, determine the intention of the target vehicle to park at the charging station;

[0034] The navigation target is the navigation destination, which includes, but is not limited to, any location such as enterprises, factories, schools, shopping malls, and service areas. It should be noted that a location containing a charging station can be used as the charging station type, or a destination that is a charging pile can be used as the charging pile type. That is, the type in this application is the charging station type.

[0035] In some embodiments, the intention of the target vehicle to park at the charging station can be identified by sending an inquiry request through the in-vehicle voice system. For example, the purpose of navigating to the charging station is not to charge or to wait for charging, or the purpose of navigating to the charging station is to charge immediately. Through voice and semantic recognition, the intention of the target vehicle to park at the charging station can be determined. For example, the first intention information includes not to charge or waiting for charging; the second intention information includes charging immediately.

[0036] In some embodiments, the intention of the target vehicle to park at the charging station can be accurately determined by analyzing the navigation destination, travel plan, and remaining battery capacity. For example, if the navigation destination is a charging station or includes a charging station, the user typically navigates to that destination to charge. Simultaneously, if the vehicle's travel plan specifies that the target vehicle's arrival time is exactly (or later than) a certain time period requiring charging, and the remaining battery capacity is below a preset level (e.g., 20%), then the intention can be determined to be immediate charging. If the vehicle's travel plan specifies that the target vehicle's arrival time is earlier than a certain time period requiring charging, or explicitly sets a non-charging or waiting-to-charge option, the current intention can be determined based on the specific circumstances.

[0037] Step S103: If the intent includes first intent information and the number of charging piles at the charging station is detected to be lower than a first preset number, then the navigation path is maintained and the driver is not reminded. The first intent information includes not charging or (queuing) waiting for charging.

[0038] It is important to understand that if the primary intent information includes not charging or waiting in line for charging, then during navigation, there is no need to switch the navigation destination; the current navigation path will be maintained, and the driver will not be alerted to avoid disturbing the driver and causing unnecessary interference.

[0039] It should be noted that the first preset number of charging piles can be set according to user needs, and is generally a small integer such as 0, 1, or 2. This indicates that the current number of charging piles at the charging station is insufficient or limited, and cannot meet the requirement that vehicles can be charged directly upon arrival at the charging station. For example, for ease of explanation, the first preset number is set to zero in this application.

[0040] Step S104: If the intent includes second intent information and the number of charging piles at the charging station is detected to be lower than the first preset number, then a backup charging scheme is generated based on the current location information and range of the target vehicle. The second intent information includes immediate charging.

[0041] It should also be understood that if the second intent information includes immediate charging and the number of charging piles at the charging station is detected to be less than zero, a backup charging plan is generated based on the current location information and driving range of the target vehicle.

[0042] Optionally, in one approach, a backup charging solution is generated based on the current location information and driving range of the target vehicle, including:

[0043] Obtain the type of charging station required for charging the target vehicle, wherein the type of charging station includes at least one of slow charging, fast charging and supercharging;

[0044] Compare the target vehicle's current remaining distance with its remaining driving range;

[0045] If the remaining driving range is less than or equal to the remaining distance, then a backup charging station close to the navigation target is selected using a preset proportion of the remaining driving range as the filtering range, and a backup charging plan is generated using the type of charging pile for the target vehicle as the filtering condition.

[0046] If the remaining driving range is greater than the remaining distance and the remaining battery power is lower than a preset battery power threshold, then the backup charging station that is close to the navigation target and matches the charging pile type of the target vehicle is selected as the filtering range to generate a backup charging plan. Each backup charging plan includes the total number of charging piles, the number of remaining charging piles, and the distance from the navigation target.

[0047] Specifically, by comparing the target vehicle's remaining distance with its remaining range, it's possible to effectively determine whether the vehicle has enough battery power to reach its destination or whether it needs to be charged en route. Since the range of electric vehicles, especially pure electric models, is significantly reduced on highways, if the remaining range is less than or equal to the remaining distance, a preset percentage of the remaining range is used as the filtering range. For example, a search radius of 70% of the remaining range is used to find alternative charging stations near the navigation target. These alternative charging stations are then selected, and a backup charging plan is generated based on the type of charging station the target vehicle uses (this ensures the selected charging station can provide the required charging method).

[0048] If the remaining driving range is greater than the remaining distance, but the remaining battery power upon arrival is less than a preset battery power threshold (e.g., 20% or 30% of the battery power), this indicates that the vehicle can reach its destination, but the battery power may be insufficient to handle emergencies or subsequent journeys. Therefore, using the navigation target as the filtering range, the system searches for backup charging stations that match the type of charging station for the target vehicle in locations close to the navigation target. Similarly, the system will generate one or more backup charging solutions.

[0049] Since each backup charging option includes the total number of charging stations, the number of remaining available charging stations, and the distance of these charging stations from the navigation target, it can effectively help drivers make quick decisions and choose the most suitable charging station for charging, and also provides drivers with flexible and practical backup charging options.

[0050] In addition, to accurately obtain the target vehicle's driving range, the actual driving range can be calculated based on the target vehicle's historical trip data, current driving data, and displayed driving range, including:

[0051] When the charging recommendation service is enabled, the historical travel data of the target vehicle is obtained from the cloud. By analyzing the historical travel data of the target vehicle, the factors affecting the driving range are obtained, including the actual driving range, the theoretical driving range consumed, temperature and vehicle speed.

[0052] The temperature and speed data from historical driving data are matched with the current driving data to determine if similar data exists. If similar data exists, the actual driving range of the target vehicle is calculated using similar historical driving data. Otherwise, historical driving data of the same vehicle model as the target vehicle, pre-stored in the cloud, is read and matched with the current driving data to determine if similar data exists. When the number of matching operations reaches a preset threshold, the actual driving range of the target vehicle is calculated based on similar historical driving data. The displayed driving range is adjusted based on the actual driving range of the target vehicle, thus obtaining a more accurate driving range.

[0053] Alternatively, in another approach, a backup charging solution is generated based on the current location information and driving range of the target vehicle, including:

[0054] Obtain the type of charging station required for charging the target vehicle, wherein the type of charging station includes at least one of slow charging, fast charging and supercharging;

[0055] Based on the driving range, the number and availability of charging piles at backup charging stations, the charging time and location of charging piles are dynamically calculated. Charging piles matching the type of charging pile are selected with the shortest charging time as the objective, and a backup charging scheme including the target charging pile location is determined.

[0056] In some embodiments, after determining the alternative charging scheme that includes the location of the target charging station, the method further includes:

[0057] A first navigation route and a second navigation route are formulated to reach the target charging station location; wherein, the first navigation route is the navigation route to reach the target charging station location in the service area; and the second navigation route is the navigation route to reach the target charging station location outside the service area.

[0058] Specifically, based on the vehicle's range, the number and availability of charging piles at backup charging stations, the charging time for each available charging pile can be dynamically calculated. Then, with the goal of minimizing charging time, charging piles matching the target vehicle's charging type are selected. This allows the target vehicle to complete charging as quickly as possible, reducing waiting time. Based on the selection results, backup charging solutions including the location of the target charging pile are determined. After determining the backup charging solutions, a first navigation route and a second navigation route are generated for the driver to reach the target charging pile location. The first navigation route is the route to the target charging pile location at a service area, typically applicable to service area charging stations on highways or long journeys; while the second navigation route is the route to the target charging pile location outside of service areas, typically applicable to independent charging stations in urban or rural areas. This approach provides drivers with a comprehensive and flexible charging solution, improving charging efficiency and time while considering the diversity of geographical locations and navigation routes. This helps enhance the driver's charging experience and avoids the phenomenon of parking and queuing at charging stations.

[0059] Step S105: In response to the first voice command, display the backup charging solution and broadcast it via voice; in response to the second voice command, select the backup charging station in the backup charging solution so that the navigation target is switched to the backup charging station for navigation.

[0060] Optionally, in some embodiments, in response to a first voice command, the backup charging solution is displayed and a voice announcement is made; in response to a second voice command, a backup charging station in the backup charging solution is selected, including:

[0061] If the first voice command received includes a switching command, the time required for the target vehicle to reach each backup charging station in the backup charging scheme is calculated. The total time for each path is determined based on the charging time and the travel time. The backup charging schemes are then sorted according to the total time and displayed in the navigation system with voice broadcast.

[0062] If the second voice command received includes any path selection command, then a backup charging station in the backup charging scheme is selected according to any path selection command, so that the navigation target is switched to the backup charging station corresponding to any path selection command for navigation.

[0063] For example, based on any route selection instruction, a corresponding backup charging station can be selected from the backup charging options. Subsequently, the navigation target will switch to the selected backup charging station, and the navigation system will begin to provide navigation services for that route.

[0064] In some embodiments, if the second voice instruction includes any path selection instruction before being received, the method further includes:

[0065] The charging cost of the target vehicle on each route is calculated based on the billing method of each backup charging station, and sorted according to the total time. At the same time, the charging cost between each backup charging scheme is displayed in the navigation system, and the displayed backup charging scheme is announced by voice.

[0066] For example, charging costs are sorted along with the previously calculated total time and displayed in the navigation system; at the same time, the total time, charging costs, and related information of alternative charging options are announced via voice broadcast so that drivers can make a more comprehensive choice.

[0067] Through the above methods, based on the driver's voice commands, the system intelligently calculates and displays alternative charging options, including information such as total time and charging costs. The driver can easily select the most suitable charging station and route through voice commands, thereby improving the convenience and efficiency of charging. At the same time, the voice command-based operation method also reduces the risk of the driver being distracted by operating the navigation system while driving, thus improving driving safety.

[0068] Optionally, before detecting that the number of charging piles at the charging station is lower than a first preset number, the method further includes:

[0069] Obtain the current location information, driving range, and average power consumption of the target vehicle;

[0070] Calculate the remaining distance between the current location of the target vehicle and the navigation target;

[0071] Based on the remaining distance, the remaining driving range, and the average power consumption, the remaining battery power of the target vehicle is estimated to reach the navigation target.

[0072] If the remaining power is lower than a preset power threshold, the number of charging piles at the charging station is detected; if the remaining power is higher than or equal to the preset power threshold, the number of charging piles at the charging station is not detected.

[0073] First, the system obtains the target vehicle's current location, remaining range, and average energy consumption. Then, it calculates the remaining distance between the target vehicle's current location and the navigation target (destination, next charging station, or other important location) to assess whether the vehicle can reach its destination without recharging. Based on the remaining distance, range, and average energy consumption, an estimate is made to determine the remaining battery power when the target vehicle reaches the navigation target. This estimate takes into account the vehicle's current state and driving needs, helping to determine whether the vehicle needs to be recharged as soon as possible.

[0074] If the estimated remaining battery power is lower than a preset battery power threshold (which is typically set based on factors such as vehicle type, driver preference, and driving conditions), the vehicle is determined to need charging. To ensure the vehicle can find an available charging station when needed, the number of charging stations nearby is monitored. If the estimated remaining battery power is higher than or equal to the preset battery power threshold, the vehicle is determined to have enough power to reach its destination or the next charging station, and therefore, the number of charging stations is not immediately monitored.

[0075] By using the methods described above, the navigation system can intelligently determine whether it is necessary to monitor the number of charging piles at charging stations based on the actual situation of the vehicle and driving needs. This helps to optimize the selection of charging stations and navigation decisions, thereby improving the driver's driving experience and safety.

[0076] In some embodiments, the remaining battery power of the target vehicle to reach the navigation target is estimated based on the remaining distance, the driving range, and the average power consumption.

[0077] Based on the remaining distance and the average power consumption, the estimated power consumption required for the target vehicle to reach the navigation target is determined;

[0078] If the remaining driving range is greater than the remaining distance, the difference between the SOC value of the remaining driving range and the estimated power consumption is calculated to determine the remaining power of the target vehicle to reach the navigation target.

[0079] In this embodiment, by accurately estimating the remaining battery power of the target vehicle when it reaches the navigation destination, more reliable charging and navigation suggestions are provided to the driver. Furthermore, by considering the vehicle's driving range and average energy consumption, it can better adapt to changes in different vehicles and driving conditions, improving the accuracy and practicality of the navigation.

[0080] Please see Figure 2 The following is a schematic diagram of the hardware architecture of another vehicle navigation intelligent planning system in this application embodiment, which is described in detail below:

[0081] It consists of a CDC (Cockpit Domain Controller), a VCU (Body Control Module), a navigation system, a voice system, a charging station location service, and a cloud platform. The navigation and voice systems are located on the CDC, while the charging station location service is located in the cloud. The cloud monitors the status of each charging station. The CDC and VCU transmit information via the CAN (Controller Area Network) protocol, and the CDC and the cloud transmit information via the MQTT (Message Queuing Telemetry Transport) protocol.

[0082] The navigation system, as part of the cockpit controller, provides functions such as route planning, map display, and navigation prompts during vehicle operation. The voice system, also part of the cockpit controller, enables in-vehicle human-machine voice interaction. The body controller transmits vehicle information to the cockpit controller via the CAN protocol, while the cockpit controller interacts with the cloud via the MQTT protocol.

[0083] Please see Figure 3 This is a schematic diagram of the complete process of a vehicle navigation intelligent planning method in an embodiment of this application, including:

[0084] Start navigation, determine the type of navigation destination, and confirm whether the navigation destination type is a charging station;

[0085] If the user selects a charging station as the navigation destination, the cloud will determine the user's charging behavior upon navigation to the destination: if the user's purpose in navigating to this charging station is not to charge or is willing to wait for charging, then if the cloud detects that there are not enough available charging piles at the destination during the navigation process, it will not remind the user.

[0086] If the user's purpose in navigating to a charging station is to charge immediately, during the navigation process, if the cloud detects that the number of available charging stations at the destination is insufficient, the cloud will search for destinations with available charging stations within the current vehicle's range based on the vehicle's current location and range. If an available charging station is found, the cloud will control the voice system to provide a voice prompt to the user and intelligently display the optimal available charging station destination based on the vehicle's supported charging type (supercharging, fast charging, slow charging). Based on the user's voice response, the cloud will control the navigation system to automatically switch to the new destination or continue navigation. This voice-based interaction for providing available charging station information and switching navigation destinations does not affect the user's driving actions. Simultaneously, it intelligently recommends the optimal charging station destination, ensuring the user's driving safety while improving charging efficiency and saving the user's time.

[0087] The specific methods for judging user charging behavior, user reminders, and the execution logic for intelligent recommendation of available charging station destinations are as follows:

[0088] First, when the user selects a charging station as the navigation destination, the cockpit controller (CDC) sends the vehicle's current location to the cloud. The navigation system then uploads the destination location information to the cloud via the CDC. The cloud uses the charging station location service to obtain the types and number of available charging stations at the destination, as well as the distance from the current location to the destination. Simultaneously, the cloud can monitor the location, distance, types, and number of available charging stations in the city where the vehicle is located in real time via the charging station location service. After navigation is activated, the average speed of the current navigation trip is uploaded to the cloud via the CDC. The vehicle control unit (VCU) uploads the vehicle's range, average energy consumption, battery level, and supported charging station types to the cloud via the CDC. The cloud uses the CDC to control the voice system and process information from the voice system.

[0089] Second, when a user actively selects a charging station as the navigation destination, the charging station's charging pile type (supercharging, slow charging, fast charging) and available quantity information are displayed to the user through the navigation system interface; the cloud determines whether there are available charging piles at the navigation destination when navigation is started, and whether the type of available charging pile matches the vehicle; if there are no available charging piles for the current vehicle, it is considered that the user is not going to this charging station for charging purposes or has the intention to wait for charging, and the current destination insufficient charging pile reminder function logic is not executed during the navigation process;

[0090] Third, when a user actively selects a charging station as their navigation destination, the charging station's charging pile type (supercharger, slow charger, fast charger) and available quantity information are directly displayed to the user through the navigation system. When the cloud determines that navigation is enabled, if the following conditions are met simultaneously, it is considered that the user intends to charge immediately at this charging station. In this case, during the navigation process, the logic for reminding the user that there are not enough available charging piles at the current destination is executed. The specific conditions are as follows:

[0091] A. When navigation is enabled, the cloud determines the available charging station types at the destination and matches them with the current vehicle's charging type;

[0092] B. The cloud calculates the remaining battery power of the vehicle when it arrives at the destination based on the real-time travel distance uploaded by the navigation system and the average power consumption information uploaded by the vehicle body controller (VCU).

[0093] During the user's navigation to their destination, the cloud monitors the number and type of available charging stations at the current destination in real time. When it detects that all available charging stations at the destination are occupied, the following logic is executed:

[0094] 1. Based on the vehicle's current driving range, the location and distance of all public charging stations in the city where the vehicle is currently located, the types of available charging stations, and the number of available charging piles uploaded by the vehicle's vehicle control unit (VCU), the cloud determines whether there are available charging piles within the vehicle's current driving range. If there are no available charging piles, navigation continues without providing voice prompts.

[0095] 2. If there is an available charging station, the cloud will control the voice system through the cockpit controller CDC to remind the user that "the current destination is full of available charging stations. Do you want to change the navigation destination?" If the user replies with a negative message such as "no", "do not change", or "continue navigation", the navigation system will continue navigation according to the user's wishes, without changing the destination, and will not remind the user again.

[0096] 3. If the user responds with confirmation messages such as "Yes," "Change," or "Change destination," the cloud calculates the time to reach the destination within the current vehicle's range and the remaining battery power based on the distance to the available charging station within the current driving range, the average speed of the current trip, the average energy consumption, and the battery level. The cloud then compares the type of charging station at the destination with the types of charging stations supported by the vehicle, matching them according to the order of supercharging, fast charging, and slow charging, and the types of charging stations supported by the vehicle. Based on the remaining battery power at the destination, the cloud calculates the available charging station range within the current driving range. The charging time to reach 80% at the destination is determined by the charging station. Available charging stations within the current driving range are sorted in ascending order of total time (total time = charging time + arrival time). The cloud-based system, via the cockpit controller CDC, controls the navigation system to display a list of available charging stations within the current driving range on the navigation interface. The system then prompts the user with the voice prompt, "Which destination do you want to select?" The user can reply with the selected destination. Based on the user's choice, the cloud-based navigation system replans the navigation destination and monitors the charging station information in real time, executing voice prompts accordingly.

[0097] 4. The waiting period for voice command responses is 30 seconds. If the user does not respond within 30 seconds, the current navigation route will continue, and no further voice prompts will be given during the entire navigation cycle.

[0098] In this embodiment, by judging the charging behavior of the charging station being navigated to by the user, the number of available charging piles at the charging station is monitored in real time during the navigation process. When there are not enough charging piles, the user is reminded by voice, and the system intelligently plans the shortest available charging station destination for the user. This improves charging efficiency, saves user time, enhances the user's driving experience, improves driving safety, and eliminates range anxiety.

[0099] Please see Figure 4 Here is a schematic diagram of the structure of a vehicle navigation intelligent planning system according to an embodiment of this application, including:

[0100] The acquisition module 401 is used to acquire the navigation target of the target vehicle, wherein the target vehicle is at least one of electric vehicles;

[0101] The intent determination module 402 is used to determine the intent of the target vehicle to park at the charging station if the type of the navigation target is a charging station;

[0102] The navigation monitoring module 403 is used to maintain the navigation path and not remind the driver if the intent includes first intent information and the number of charging piles at the charging station is less than a first preset number. The first intent information includes not charging or waiting to charge.

[0103] The scheme planning module 404 is used to generate an alternative charging scheme based on the current location information and driving range of the target vehicle if the intent includes second intent information and the number of charging piles of the charging station is detected to be lower than a first preset number. The second intent information includes immediate charging.

[0104] The route switching module 405 is used to respond to a first voice command, display the backup charging scheme and make a voice broadcast, and respond to a second voice command, select a backup charging station in the backup charging scheme, so that the navigation target is switched to the backup charging station for navigation.

[0105] In the vehicle navigation intelligent planning system, the acquisition module 401, intent determination module 402, navigation monitoring module 403, scheme planning module 404, and path switching module 405 collaboratively execute the steps in steps S101-S105 described above, according to the functions of each module. Further details are omitted here.

[0106] The vehicle navigation intelligent planning system provided in this embodiment obtains the navigation target of the target vehicle. If the type of the navigation target is a charging station, the system determines the target vehicle's intention to park at the charging station, thereby improving the navigation experience through intention recognition. If the intention includes first intention information and the number of charging piles at the charging station is detected to be lower than a first preset number, the navigation path is maintained without reminding the driver, avoiding unnecessary interference. If the intention includes second intention information and the number of charging piles at the charging station is detected to be lower than a first preset number, a backup charging plan is generated based on the target vehicle's current location information and remaining range. In this way, through dynamic resource monitoring and decision optimization, the system effectively improves navigation performance. This system improves the convenience and efficiency of charging. Responding to a first voice command, it displays and announces the backup charging plan. Responding to a second voice command, it selects a backup charging station from the backup charging plan, allowing the navigation target to switch to that station. On one hand, by selecting a backup charging station according to user needs, the system enables rapid switching of navigation targets. The voice interaction simplifies the operation process, prevents accidental operation while driving, and improves driving safety. On the other hand, by planning backup charging plans in advance, it ensures that the vehicle can reach a suitable charging station before its battery runs out, avoiding driving interruptions due to insufficient power and improving the energy efficiency and driving safety of electric vehicles.
