Description

Technical Field

[0001] The present invention relates to the technical field of tram navigation, and in particular to a vehicle navigation intelligent planning method, system and electronic equipment. Background Art

[0002] With the progress of society and the continuous improvement of people's living standards, new energy vehicles (electric vehicles) have gradually integrated into people's lives and become an indispensable means of transportation. Now many new energy vehicle owners are becoming more and more anxious when driving and navigating as the range gradually decreases. When driving on the highway, the range will be more discounted at high speeds, which makes the owners unsure about the actual range. If they miss a service area, they may not be able to reach the next service area.

[0003] However, during the navigation process, the recommended charging locations are dynamically calculated in real time, so that drivers can have an idea of ​​the location and reduce charging anxiety. This can avoid the situation where there are no available charging piles when users arrive at the navigation destination to charge, resulting in insufficient power for new energy vehicles or increased waiting time for users to charge, thereby reducing the user experience of new energy vehicles.

In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0026] Unless otherwise stated, the term "plurality" means two or more.

[0027] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B indicates: A or B.

[0028] The term "and / or" is a description of the association relationship 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, the embodiment of the present disclosure provides a flow chart of a vehicle navigation intelligent planning method, including:

[0030] Step S101, obtaining a navigation target of a 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 vehicles, extended-range hybrid vehicles, etc. The navigation target refers to a navigation destination received from a user.

[0032] For example, after getting in the vehicle, the user opens the vehicle's built-in navigation system and enters "Chongqing Jiefangbei" in the navigation system. At this time, the navigation target "Chongqing Jiefangbei" takes the current location information as the starting point and corresponds to the end point.

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

[0034] Among them, the navigation target is the navigation destination, including but not limited to any place such as enterprises, factories, schools, shopping malls, service areas, etc. It should be noted that the place containing the charging station can be regarded as the charging station type, and the destination that is the charging pile can be regarded 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 is identified, and an inquiry request can be sent through the vehicle-mounted voice system. For example, the purpose of navigating to the charging station is not to charge or to be willing to wait for charging, or the purpose of navigating to the charging station is to charge immediately. The intention of the target vehicle to park at the charging station is determined through voice and semantic recognition. For example, the first intention information includes not charging or waiting for charging; the second intention information includes immediate charging.

[0036] In some embodiments, the intention of the target vehicle to park at the charging station can also 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 usually navigates to the destination for charging. At the same time, if the vehicle travel plan stipulates that the target vehicle needs to be charged when it arrives just in (or later than) a certain time period, and at the same time, the remaining battery capacity is lower than a preset power level (for example, 20% power), if the above conditions are met at the same time, it can be determined that the intention is to charge immediately. If the vehicle travel plan stipulates that the target vehicle needs to be charged when it arrives earlier than a certain time period, or it is clearly set that it needs to be non-charged or wait for charging, in this case, it can be determined whether the current intention is non-charging or waiting for charging according to the specific situation.

[0037] Step S103, if the intention includes first intention information, and the number of charging piles at the charging station is monitored to be less than a first preset number, the navigation path is maintained and the driver is not reminded, and the first intention information includes non-charging or (queueing) waiting for charging;

[0038] It should be understood that if the first intention information includes non-charging or (queueing) waiting for charging, then during the navigation process, there is no need to switch the navigation destination, the current navigation path is maintained, and the driver is not reminded 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, generally a small integer such as 0, 1, 2, etc., which is used to indicate that the current number of charging piles at the charging station is insufficient or tight, and the vehicle cannot be directly charged after arriving at the charging station. For example, for the sake of convenience, the first preset number in this application is taken as zero.

[0040] Step S104, if the intention includes second intention information, and the number of charging piles at the charging station is monitored to be lower than the first preset number, a backup charging plan is generated based on the current location information and cruising range of the target vehicle, and the second intention information includes immediate charging;

[0041] It is also necessary to understand that if the second intention information includes immediate charging, and the number of charging piles at the charging station is monitored to be less than zero, a backup charging plan is generated based on the current location information and cruising range of the target vehicle.

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

[0043] Obtaining a charging pile type required for charging the target vehicle, wherein the charging pile type includes at least one of slow charging, fast charging, and super charging;

[0044] Comparing the current remaining distance of the target vehicle with the cruising range;

[0045] If the cruising range is less than or equal to the remaining distance, a preset proportion of the cruising range is used as a screening range, a backup charging station close to the navigation target is selected, and the target vehicle charging pile type is used as a screening condition to generate a backup charging plan;

[0046] If the cruising range is greater than the remaining distance and the remaining power is lower than the preset power threshold, the navigation target is used as the screening range, and a backup charging station close to the navigation target and a backup charging station that matches the charging pile type of the target vehicle is selected to generate a backup charging plan, wherein each backup charging plan includes the total number of charging piles, the remaining number, and the distance between the navigation target.

[0047] Specifically, by comparing the current remaining distance of the target vehicle with the cruising range, it is possible to effectively determine whether the vehicle has enough power to reach the destination, or whether it needs to be charged midway. Since the cruising range of electric vehicles, especially pure electric vehicles, is severely discounted when running on highways. Therefore, if the cruising range is less than or equal to the remaining distance, a preset proportion of the cruising range is used as the screening range. For example, 70% of the cruising range is used as the search radius. Within this range, find a backup charging station close to the navigation target, select a backup charging station close to the navigation target, and use the target vehicle charging pile type as the screening condition (screen according to the charging pile type of the target vehicle to ensure that the selected charging station can provide the required charging method), and generate a backup charging plan.

[0048] If the cruising range is greater than the remaining distance, but the remaining power after arrival is lower than the preset power threshold (for example, 20% or 30% of the battery power), this situation means that the vehicle can reach the destination, but the power may not be enough to cope with emergencies or subsequent trips. Therefore, with the navigation target as the screening range, the system searches for a backup charging station that matches the charging pile type of the target vehicle near the navigation target. Similarly, the system generates one or more backup charging solutions.

[0049] Since each backup charging plan includes the total number of charging piles, the number of remaining available charging piles, and the distance between these charging stations and the navigation target, it can effectively help drivers make decisions quickly and choose the most suitable charging station for charging, while also providing drivers with flexible and practical backup charging plan options.

[0050] In addition, in order to accurately obtain the cruising range of the target vehicle, the actual cruising range of the vehicle can also be calculated based on the historical travel data of the target vehicle, as well as the current driving data and the displayed cruising range, including:

[0051] When the charging recommendation service is turned on, the historical travel data of the target vehicle pre-stored in the cloud is obtained; by analyzing the historical travel data of the target vehicle, the factors affecting the cruising range are obtained, including the actual mileage, the consumed theoretical cruising range, the temperature and the vehicle speed;

[0052] Based on the temperature and speed of the historical driving data, the current driving data is matched to determine whether there is data in the current driving data that is similar to the temperature and speed of the historical driving data; if so, similar historical travel data is obtained to calculate the actual cruising range of the target vehicle; otherwise, historical travel data of the same model as the target vehicle pre-stored in the cloud is read, and based on the temperature and speed of the historical driving data of the same model as the target vehicle, the current driving data is matched to determine whether there is data in the current driving data that is similar to the temperature and speed of the historical driving data of the same model as the target vehicle; when the number of matching operations reaches a preset threshold, the actual cruising range of the target vehicle is calculated based on historical travel data similar to the same model as the target vehicle; based on the actual cruising range of the target vehicle, the displayed cruising range is adjusted, so that a more accurate cruising range can be obtained.

[0053] Optionally, in another manner, planning is performed based on the current location information and cruising range of the target vehicle to generate a backup charging plan, including:

[0054] Obtaining a charging pile type required for charging the target vehicle, wherein the charging pile type includes at least one of slow charging, fast charging, and super charging;

[0055] The charging time and the location of the charging piles are dynamically calculated based on the cruising range, the number of charging piles at the backup charging station, and the idle status. The charging piles that match the type of charging piles are selected with the shortest charging time as the goal, and a backup charging plan that includes the target charging pile location is determined.

[0056] In some embodiments, after determining the backup charging solution including the target charging pile location, the method further includes:

[0057] A first navigation route and a second navigation route are formulated to reach the target charging pile location; 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 in the non-service area.

[0058] Specifically, according to the vehicle's cruising range, the number of charging piles at the backup charging station and the idle situation, the charging time of each available charging pile can be dynamically calculated. After that, with the shortest charging time as the goal, the charging piles that match the charging pile type of the target vehicle are screened out, so that the target vehicle can complete charging as soon as possible and reduce the waiting time. According to the screening results, the backup charging plan containing the target charging pile location is determined. After determining the backup charging plan, the driver is provided with a first navigation route and a second navigation route to reach the target charging pile location, wherein the first navigation route is a route to reach the target charging pile location in the service area, which is usually applicable to the charging station in the service area on a highway or long-distance trip; and the second navigation route is a route to reach the target charging pile location in the non-service area, which is usually applicable to independent charging stations in urban or rural areas. In the above manner, a comprehensive and flexible charging solution is provided for the driver, which not only improves the charging efficiency and time, but also takes into account the diversity of geographical locations and navigation routes, which helps to improve the driver's charging experience and avoids the phenomenon of parking and queuing at the charging station to wait for charging.

[0059] Step S105, in response to the first voice command, display the backup charging plan and perform voice broadcasting, and in response to the second voice command, select the backup charging station in the backup charging plan 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, displaying the backup charging scheme and performing voice broadcasting, and in response to a second voice command, selecting a backup charging station in the backup charging scheme, including:

[0061] If the first voice instruction received includes a switching instruction, the time required for the target vehicle to reach each backup charging station in the backup charging solution is calculated, the total time of each path is determined according to the charging time and the distance time, and the backup charging solution is displayed in the navigation system and voice broadcast is performed according to the total time.

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

[0063] For example, a corresponding backup charging station is selected from the backup charging scheme according to any route selection instruction, and then the navigation target is switched to the selected backup charging station, and the navigation system starts to provide navigation services for the route.

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

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

[0066] For example, the charging cost is sorted together with the previously calculated total time and displayed in the navigation system. At the same time, the total time, charging cost and related information of the alternative charging options are announced by voice so that the driver can make a more comprehensive choice.

[0067] In the above manner, according to the driver's voice commands, the alternative charging plans are intelligently calculated and displayed, including information such as total time and charging costs, so that the most suitable charging station and route can be easily selected through voice commands, thereby improving the convenience and efficiency of charging; at the same time, the operation method based on voice commands also reduces the risk of the driver being distracted by operating the navigation system while driving, thereby improving driving safety.

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

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

[0070] Calculating the remaining distance between the current position information of the target vehicle and the navigation target;

[0071] Determine the remaining power of the target vehicle to reach the navigation target by estimating the remaining distance, the cruising range and the average power consumption;

[0072] If the remaining power is lower than the preset power threshold, the number of charging piles at the charging station is monitored; 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 monitored.

[0073] First, the current location information, cruising range, and average power consumption of the target vehicle are obtained. Then, the remaining distance between the current location of the target vehicle and the navigation target (destination, next charging station, or other important location) is calculated to evaluate whether the vehicle can reach the destination without charging. An estimate is made based on the remaining distance, cruising range, and average power consumption to determine the remaining power of the target vehicle when it reaches the navigation target. This estimate takes into account the current state of the vehicle and driving needs, which helps to determine whether the vehicle needs to be charged as soon as possible.

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

[0075] Through the above method, according to the actual situation and driving needs of the vehicle, the navigation system can intelligently determine whether it is necessary to monitor the number of charging piles at the charging station. This helps to optimize the selection of charging stations and navigation decisions, and improve the driver's driving experience and safety.

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

[0077] Calculating based on the remaining distance and the average power consumption, determining the estimated power consumption required for the target vehicle to reach the navigation target;

[0078] If the cruising range is greater than the remaining distance, the difference between the SOC value of the cruising 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 power of the target vehicle when it reaches the navigation target, more reliable charging and navigation suggestions are provided to the driver. At the same time, by considering the vehicle's cruising range and average power consumption, it can also better adapt to changes in different vehicles and driving conditions, thereby improving the accuracy and practicality of navigation.

[0080] See also Figure 2 , is another schematic diagram of the hardware architecture of the vehicle navigation intelligent planning system in the embodiment of the present application, which is described in detail as follows:

[0081] It consists of CDC (Cockpit Domain Controller), body control module VCU (body control module), navigation system, voice system, charging station location service and cloud. The navigation system and voice system are arranged on the cockpit controller CDC, and the charging station location service is arranged on the cloud. The status of each charging station is monitored through the cloud. The cockpit controller CDC and the body controller VCU transmit information through the CAN (Controller Area Network) protocol, and the cockpit controller CDC and the cloud transmit information through the MQTT (Message Queuing Telemetry Transport, a message transmission protocol based on the publish / subscribe mode) protocol.

[0082] Among them, the navigation system, as a part of the cockpit controller, is used to provide functions such as route planning, map display, and navigation prompts during vehicle driving; the voice system, as a part of the cockpit controller, is used to realize the human-computer voice interaction function in the car. The body controller transmits vehicle information to the cockpit controller through the CAN protocol, and the cockpit controller and the cloud interact with each other through the MQTT protocol.

[0083] See also Figure 3 , is a complete flow chart of a vehicle navigation intelligent planning method in an embodiment of the present application, including:

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

[0085] If the navigation destination type selected by the user is a charging station, the cloud will determine the charging behavior of the user when navigating to the destination: if the user navigates to this charging station for non-charging purposes or is willing to wait for charging, during the navigation process, if the cloud detects that the number of available charging piles at the destination is insufficient, no user reminder will be given;

[0086] If the user navigates to a charging station for the purpose of charging immediately, then during the navigation process, if the cloud detects that the number of available charging piles at the destination is insufficient, the cloud searches for a destination with available charging piles within the current vehicle range based on the vehicle's current location and range. If there is information about a destination with available charging piles, the voice system is controlled to give a voice reminder to the user, and the navigation system is controlled to intelligently show the user the best destination with available charging piles based on the charging type (supercharging, fast charging, slow charging) supported by the vehicle. The cloud controls the navigation system to automatically switch to a new destination or continue navigating based on the user's voice reply command information fed back by the voice system. The interaction of available charging pile information reminders and navigation destination switching is performed by voice, which does not affect the customer's driving actions, and intelligently recommends the best charging pile destination to the user, ensuring the safety of the user's vehicle driving while improving the user's charging efficiency and saving the user's time.

[0087] The specific user charging behavior judgment method, user reminder and available charging station destination intelligent recommendation execution logic are as follows:

[0088] First, when the navigation destination selected by the user is a charging station, the cockpit controller CDC sends the current location of the vehicle to the cloud, and the navigation system uploads the navigation destination location information to the cloud through the cockpit controller CDC. The cloud obtains the type of idle charging piles and the number of idle charging piles of the navigation destination and the mileage from the current location to the destination based on the charging station location service. At the same time, the cloud can monitor the location, distance, type and number of idle charging piles of all public charging stations in the city where the vehicle is located in real time through the charging station location service; after the navigation is turned on, the average speed of the current navigation trip is uploaded to the cloud through the cockpit controller CDC; the body controller VCU uploads the vehicle's cruising range, average power consumption, battery power and supported charging pile types to the cloud through the cockpit controller CDC; the cloud controls the voice system and processes information of the voice system through the cockpit controller CDC.

[0089] Second, when the user actively selects a charging station as the navigation destination, the charging pile type (supercharge, slow charge, fast charge) and available number information of the charging station are displayed to the user through the navigation system interface; when the navigation is turned on, the cloud determines whether there are idle charging piles at the navigation destination and whether the type of idle charging piles matches the vehicle; if there are no available charging piles for the current vehicle, it is considered that the user does not come to this charging station for charging purposes or intends to wait for charging, so during the navigation process, the reminder function logic of insufficient available charging piles at the current destination will not be executed;

[0090] Third, when the user actively selects a charging station as the navigation destination, the charging pile type (supercharge, slow charge, fast charge) and available number information of the charging station are directly displayed to the user through the navigation system; when the cloud determines that navigation is turned on, if the following conditions are met at the same time, it is considered that the user has the intention to charge immediately at this charging station, and during the navigation process, the logic of the reminder function of insufficient available charging piles at the current destination is executed. The specific conditions are as follows:

[0091] A. When navigation is turned on, the cloud determines that the available charging pile type at the destination matches the charging type of the current vehicle;

[0092] B. The cloud calculates the remaining power of the vehicle when arriving 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, and the remaining power of the vehicle is ≤50%;

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

[0094] 1. The cloud determines whether there are available charging piles within the current range of the vehicle based on the current range of the vehicle uploaded by the vehicle body controller VCU, the location and distance of all public charging stations in the city where the current vehicle is located, the types of available charging stations, and the number of available charging piles. If there are no available charging piles, navigation will continue without voice reminders;

[0095] 2. If there are available charging piles, the cloud will control the voice system through the cockpit controller CDC to give a voice reminder "The available charging piles at the current destination are full, do you want to change the navigation destination?" If the user replies with negative information such as "No, do not change, continue navigation" through voice, the navigation system will continue navigating according to the user's wishes, and will not change the destination, and will not give voice reminders later;

[0096] 3. If the user replies with confirmation information such as "yes, change, change destination" by voice, the cloud will calculate the time to reach the destination of available charging piles within the current vehicle's cruising range and the remaining power to reach the destination of available charging piles within the current vehicle's cruising range based on the destination distance with available charging piles within the current vehicle's cruising range, the average speed of the current trip, the average power consumption, and the battery power; the cloud will compare the charging pile types at the destination of available charging piles within the current vehicle's cruising range with the types of charging piles supported by the current vehicle, match them according to the order of supercharging, fast charging, and slow charging charging pile types and the types of charging piles supported by the vehicle, and calculate the available charging piles within the current vehicle's cruising range based on the remaining power of the current vehicle when arriving at the charging pile destination. The fastest charging time for the charging pile destination to charge to 80% is calculated, and the available charging pile destinations within the current cruising range are sorted in order from small to large according to the total time (total time = charging time + time to reach the destination); the cloud controls the navigation system through the cockpit controller CDC to display the sorted information of available charging pile destinations within the current vehicle cruising range in the form of a list on the navigation interface; and controls the voice system again to ask the user "which destination please choose", and the user can reply with the destination information by voice to select the navigation destination; the cloud controls the navigation system to re-plan the navigation destination according to the destination information selected by the user, monitor the charging pile information of the new destination in real time, and execute the voice reminder logic.

[0097] 4. The waiting period for voice command replies is 30 seconds. If the user does not respond within 30 seconds, the current navigation itinerary will continue to be executed, and no voice reminders will be given during the entire navigation cycle.

[0098] In this embodiment, the charging behavior of the charging station navigated by the user is judged, and the available number of charging piles at the charging station is monitored in real time during the navigation process. When the charging piles are insufficient, the user is reminded by voice, and the available charging station destination with the shortest time is intelligently planned for the user, thereby improving the charging efficiency, saving the user's time, and enhancing the user's car experience, as well as improving driving safety and eliminating mileage anxiety.
