[0040] Embodiments of the present disclosure will be described in detail below with reference to Figures 1 to 10 the accompanying drawings.

[0041] Figure 1 is a block diagram showing the internal configuration of a driving information display device 101 according to various exemplary embodiments of the present disclosure.

[0042] The driving information display device 101 according to an exemplary embodiment of the present disclosure may be provided inside a vehicle (such as a vehicle), or may be implemented in a detachable form. The driving information display device 101 may generally be in the form of a vehicle navigation system, an audio, video, and navigation (AVN) system, a head-up display (HUD), etc., and may be implemented in the form of an application installed on a mobile phone terminal such as a smart phone.

[0043] The driving information display device 101 according to an exemplary embodiment of the present disclosure may exist in the form of a server outside a vehicle (e.g., a vehicle). In this case, the driving information display device 101 may be implemented to generate driving guidance information by processing determinations while existing outside the vehicle, and output the driving guidance information to a display existing inside the vehicle. In addition, various embodiments may be implemented. The scope of the rights of the present disclosure is not limited by the forms of these implementations.

[0044] In addition, the driving information display device 101 of the exemplary embodiments of the present disclosure may operate in combination with devices for autonomous driving control, such as an advanced driver assistance system (ADAS), a smart cruise control (SCC) system, a forward collision warning (FCW) system, etc.

[0045] As shown in the figure, the driving information display device 101 according to an exemplary embodiment of the present disclosure may include a processor 110, a storage unit 120, a communication unit 130, and an output unit 140.

[0046] The processor 110 is configured to control the storage unit 120, the communication unit 130, and the output unit 140 to execute an application, process data according to an algorithm defined in the application, communicate with an external module, and provide a processing result to a user.

[0047] The processor 110 may refer to a chip for processing general algorithms (e.g., a central processing unit (CPU) or an application processor (AP)) or a collection of such chips. The processor 110 may refer to a chip optimized for floating-point operations (e.g., general-purpose graphics processing unit computing (GPGPU)) to process artificial intelligence algorithms such as deep learning or a collection of such chips. Alternatively, the processor 110 may refer to a module in which various types of chips execute algorithms and process data in a connected and distributed manner.

[0048] The processor 110 may be electrically connected to the storage unit 120 and the communication unit 130, may electrically control each component, may be a circuit that executes software commands, and may perform various types of data processing and determination described later. The processor 110 may be, for example, an electronic control unit (ECU), a microcontroller unit (MCU), or another low-level controller installed on a vehicle.

[0049] The storage unit 120 stores road information and algorithms executed by the processor. The road information may include map information, road traffic condition information, etc. According to the configuration of the driving information display device 101 of the present disclosure, the form or amount of the road information stored inside the driving information display device 101 may vary.

[0050] In some cases, the storage unit 120 may store road information including map information and traffic condition information of all serviceable areas and provide services based on the road information. Alternatively, the storage unit 120 may only temporarily store road information about the position being guided and provide services based on the temporarily stored road information.

[0051] Depending on the form in which the driving information display device 101 according to an exemplary embodiment of the present disclosure is implemented inside or outside a vehicle, the communication method used, the storage space of the storage unit 120, and / or the input / output speed, this may be implemented in different forms. This is a part that those skilled in the art can autonomously select according to the implementation. The scope of the rights of the present disclosure is not limited by such changes in the implementation.

[0052] The road information stored in the storage unit 120 can include not only general road information but also information about the location, capacity, and number of chargers of charging stations for electric vehicles. Based on these types of information, driving information guidance considering the charging situation can be provided.

[0053] In addition, the road information stored in the storage unit 120 can include various types of display information to be displayed in the guidance information. The display information can include various types of information to be included in the guidance information displayed in driving situations, such as intersections, traffic lights, crosswalks, destinations, and major landmarks. In addition, the display information included in the road information can include parking positions, entrance positions, ramps for moving between floors, indoor facilities, road information outside the indoor area connected to the exit, etc., for guiding inside the indoor area. Such display information can each include a combination of the name of the display information to be displayed as the guidance information and information about the position where the corresponding display information will be displayed.

[0054] The storage unit 120 can have various forms and can be at least one type of storage medium, such as flash memory, hard disk, micro, card (e.g., Secure Digital (SD) card), Extreme Digital (XD) card, Random Access Memory (RAM), Static RAM (SRAM), Read Only Memory (ROM), Programmable ROM (PROM), Electrically Erasable PROM (EPROM), Magnetic Random Access Memory (MRAM), magnetic disk, or optical disk type of storage medium, etc. Different types of storage media or combinations of different types of storage media can be selected according to the amount of data to be stored, processing speed, storage time, etc.

[0055] The algorithms stored in the storage unit 120 can be implemented as computer programs in executable form and can be implemented to be stored in the storage unit 120 and then executed when needed. The algorithms stored in the storage unit 120 can be interpreted as including instructions temporarily loaded into volatile memory and instructing the processor to perform specific operations.

[0056] The communication unit 130 receives information for driving guidance from outside the driving information display device 101 of the present disclosure through a wired / wireless communication network and sends necessary information to an external module.

[0057] The communication unit 130 may receive road information stored in the storage unit 120, algorithms executed by the processor 110, etc. from an external module, and may send information about the current state of the vehicle to the outside to obtain necessary information related to the sent information. For example, the communication unit 130 may continuously receive traffic information from a traffic information server to check real-time traffic information, and is configured to send the position and route information of the vehicle discovered by a module such as a global positioning system (GPS) receiver to the outside to obtain real-time traffic information of an area related to the position and route of the vehicle.

[0058] In addition, the communication unit 130 may be configured to send internal and external information of the vehicle and receive information required for driving guidance while communicating with a driving information management server 201, and the driving information management server 201 may process and provide information required for driving information guidance.

[0059] The communication unit 130 is a hardware device implemented using various electronic circuits to send and receive signals through wireless or wired connections. In an exemplary embodiment of the present disclosure, the communication unit 130 may perform communication within the vehicle using in-vehicle network communication technology, and may perform vehicle-to-infrastructure (V2I) communication with a server, infrastructure, another vehicle, etc. outside the vehicle using wireless Internet access or short-range communication technology. In this case, communication within the vehicle may be performed using controller area network (CAN) communication, local interconnect network (LIN) communication, FlexRay communication, etc. as in-vehicle network communication technology. In addition, such wireless communication technologies may include wireless LAN (WLAN), wireless broadband (WiBro), Wi-Fi, worldwide interoperability for microwave access (WiMAX), etc. In addition, short-range communication technologies may include Bluetooth, ZigBee, ultra-wideband (UWB), radio frequency identification (RFID), infrared data association (IrDA), etc.

[0060] The output unit 140 may output augmented reality information controlled by executing an algorithm stored in the storage unit 120 through the processor 110. Augmented reality is a technology that enables relevant information to be provided by adding graphic information to an image or scene of the real world.

[0061] The output unit 140 may be implemented as a head-up display (HUD), an instrument panel, an audio, video, and navigation (AVN) system, a human-machine interface (HMI), etc. In addition, the output unit 140 may include at least one of a liquid crystal display (LCD), a thin film transistor liquid crystal display (TFT LCD), a light-emitting diode (LED) display, an organic light-emitting diode (OLED) display, an active matrix OLED (AMOLED) display, a flexible display, a curved display, and a three-dimensional (3D) display. Some of these displays may be implemented as transparent displays configured to be transparent or semi-transparent to enable viewing of the outside. In addition, the output unit 140 may be provided as a touch screen including a touch panel and may be used as both an input device and an output device.

[0062] In an exemplary embodiment of the present disclosure, a vehicle may be referred to based on a concept including various transportation means. In some cases, a vehicle may be interpreted based on a concept including not only various land transportation means traveling on roads (such as cars, motorcycles, trucks, and buses) but also various transportation means (such as airplanes, drones, ships, etc.).

[0063] Therefore, in an exemplary embodiment of the present disclosure, an electric vehicle may be interpreted based on a concept including various transportation means among which electric energy is stored in a secondary battery and used as a power source.

[0064] Depending on the method by which the processor 110 processes information providing guidance, the driving information display device 101 according to an exemplary embodiment of the present disclosure may have different exemplary embodiments. Thus, the functions of the processor 110 will be described in detail through specific embodiments below.

[0065] As described above, the processor 110 is configured to perform control to receive driving guidance information and information about the position of the electric vehicle and output a guidance screen corresponding to the driving guidance information. In this case, the driving guidance information may include various types of information. When the driver sets a destination and wants to receive guidance information related to the destination through the screen, the driving guidance information may include information about the destination and the route leading to the destination. Various other types of information for guiding the driving of the vehicle may be included in the driving guidance information.

[0066] In the case of an electric vehicle, the driving range is short, the charging takes a long time, and the number of charging stations is insufficient, making it important to provide accurate guidance on charging stations during route guidance to pass by a charging station. Therefore, the processor 110 may be configured to provide guidance on the optimal route by using the electric vehicle charging station information included in the map information stored in the storage unit 120, along which the driver can safely drive to the destination while charging the electric vehicle at necessary points.

[0067] The processor 110 is configured to execute control to receive driving guidance information regarding the position of the vehicle and output a guidance screen corresponding to the driving guidance information. When the driver sets a destination and wants to receive guidance information related to the destination through the screen, the driving guidance information may include information about the destination and the route leading to the destination. Various other types of information for vehicle driving guidance may be included in the driving guidance information.

[0068] The driving guidance information received by the processor 110 may be information received from the user (e.g., the destination), or may be information generated using the information stored in the storage unit 120 (e.g., route information).

[0069] As described above, the position information of the vehicle received by the processor 110 may be position information determined by a global positioning system (GPS) module, etc., and may be represented in a form that can be matched on the map information stored in the storage unit 120.

[0070] When providing route guidance after the driver inputs a destination, when a charging station is included in the destination or waypoint of the electric vehicle, the processor 110 checks whether the driver has reached the charging station included in the destination or waypoint.

[0071] When the electric vehicle reaches the charging station, the processor 110 checks whether the charging station image output condition is satisfied, and is configured to execute control to output the charging station image of the reached charging station through the output unit 140 when the charging station image output condition is satisfied.

[0072] Traditional driving information display devices only provide route guidance on the location of electric vehicle charging stations or briefly display charging station-related information. However, traditional driving information display devices have limitations in accurately determining and providing information on the charging station status and can only provide simple information, making it difficult to accurately provide the latest charging station status information. Thus, by providing the driver using the charging station with the most recently captured charging station image, the driver can more accurately and clearly understand the status of the charging station.

[0073] In another exemplary embodiment of the present disclosure, the processor 110 may be configured to perform control to: when the destination or waypoint includes a charging station, even before the electric vehicle reaches the charging station, output an image of the charging station and allow the driver to determine whether to access the charging station corresponding to the output image of the charging station.

[0074] In this way, the driver can accurately determine the status of the charging station included in the destination or waypoint through the image of the charging station at the time of departure. When it is determined that the status of the charging station is not suitable for use, the driver can select another charging station as the destination or waypoint.

[0075] The processor 110 may be configured to: when the destination or waypoint of the electric vehicle includes a charging station, first provide the driver with an image of the charging station, and when the driver expresses his or her intention not to use the charging station, search for other charging stations other than the corresponding charging station to find the best charging station, and then provide the best charging station to the driver. In this way, the driver can accurately determine the status of the charging station through the image of the charging station and select and use the desired charging station.

[0076] The processor 110 outputs the image of the charging station only when the charging station image output condition is satisfied. The reason is to ensure that the image of the charging station is output only when necessary, because when the image of the charging station is displayed on the output unit 140, other screens such as route guidance may be blocked by the image of the charging station.

[0077] The charging station image output condition may be that the number of times the driver of the electric vehicle has visited the charging station in the past is less than a predetermined reference number. In the case of a charging station frequently used by the driver, even when the image of the charging station is not provided, the driver may already know the location and status of the charging station, so it may be more convenient not to output the image of the charging station.

[0078] The reference number is the number of visits that allows the driver to get used to using the charging station, and can be set to about five times. The reference number can be set differently for each driver, and the reference number can be determined according to the value set by the driver for the vehicle.

[0079] In addition, the processor 110 not only outputs the image of the charging station for a charging station with fewer visits than the fixed reference number, but can also determine whether to output the image of the charging station by checking the number of times the driver has visited the charging station within a predetermined recent period. In the case where a charging station has been frequently used in the past but has not been used recently, variables such as a change in the location of the charger or a charger failure may occur. When the charging station has not been used recently, it may be desirable to provide the driver with an image of the charging station.

[0080] In this way, the processor 110 can be configured to generate a charging station image output condition by combining information about the driver's past and most recent visits to each charging station. This combination method can also be configured to be set by the driver in the vehicle.

[0081] In addition, the charging station image output condition can be configured to be satisfied when the time elapsed from the time point when the electric vehicle arrives at the charging station to the time point when the parking completion signal is received exceeds a predetermined reference time. When the driver arrives at the charging station and after a period of time has passed without completing parking and starting charging, it is highly likely that the driver has failed to find a charger capable of charging.

[0082] Therefore, the processor 110 can output a charging station image after a period of time has passed since the electric vehicle arrived at the charging station without parking the electric vehicle, so that the driver can view the image and find a charger.

[0083] In addition, the charging station image output condition can be set to vary according to status information such as time and weather or the driver's situation. For example, when it is difficult to find the location of the charger at night or when it is raining, the charging station image can be output even when other conditions are not met. In addition, when the charging station is the destination, the charging station image can be output regardless of other conditions. On the contrary, when the charging station is a waypoint, the charging station image can be output only when other conditions are met.

[0084] The processor 110 can also provide charging station information about the corresponding charging station when outputting the charging station image. The charging station information can include all types of information that can be used as a reference for using the charging station, such as charger location, charger manager contact information, charger capacity (kW) information, information related to the number of chargers, working hours, and fees. This information can be information stored in a previously established charging station information database associated with a charging station identifier.

[0085] The processor 110 can execute control to receive charging station information including a charging station image from the driving information management server 201 through the communication unit 130 and output the received charging station information through the output unit 140.

[0086] The charging station information output together with the charging station image can be output together with the charging station image when the charging station image output condition is satisfied. When the charging station image output condition is not satisfied, the charging station information can be displayed as a pop-up message so as not to obscure the route guidance information.

[0087] In addition, the processor 110 may add charging station related information to the charging station image to be displayed, and then use augmented reality technology to output the charging station image. When augmented reality technology is used, the driver can check the charging station related information at a glance while viewing the charging station image, thus allowing the driver to conveniently use the charging station information.

[0088] In addition, the processor 110 may identify a region corresponding to the charging station image in the image around the vehicle received through the vehicle's camera by using image processing technology using artificial intelligence, and may use augmented reality technology to output the charging station related information to the identified region. In addition, various methods can be applied to the display of the charging station information.

[0089] In order to be able to check the latest charging station status through the charging station image output via the output unit 140, the charging station image needs to be continuously updated. When receiving the charging station image from the charging station manager or management company, it may not be possible to check the continuous status information, and the situation of the provided image may be different from the actual situation.

[0090] Therefore, when the electric vehicle arrives at the charging station and the charging port of the electric vehicle is opened, the processor 110 may execute control to capture an image using the camera attached to the electric vehicle and send the captured image together with the information for identifying the arrived charging station to the driving information management server 201.

[0091] When the electric vehicle arrives in front of a charger at the charging station and starts charging, the charging port is opened. Therefore, in this case, when the vehicle captures the charging station image and sends the charging station image to the server so that it can be managed, the latest charging station image can be provided to other vehicles for future use.

[0092] In order to capture the accurate status of the charger, the processor 110 may execute control to: select one camera from the multiple cameras attached to the electric vehicle based on the information about the direction where the charging port of the electric vehicle is located, and capture an image of the charger.

[0093] When the charging port of the electric vehicle is located at the front of the vehicle, the front of the vehicle faces the charger, so that the charging station image can be captured by the camera capturing the front area of the vehicle. On the contrary, when the charging port of the electric vehicle is located at the rear of the vehicle, the rear of the vehicle faces the charger, so that the charging station image can be captured by the camera capturing the rear area of the vehicle.

[0094] In some cases, the charger may be located on the side of the vehicle, in which case the camera located on the side of the vehicle can be used. Even in this case, the side camera located in the direction of the charging port of the vehicle can be used.

[0095] For this purpose, the processor 110 may refer to the information in the database that stores information about the position of the charger in the charging station where the electric vehicle arrives relative to the position of the vehicle.

[0096] The camera that captures the image of the charging station may be a built-in camera that captures the image in front of or behind the electric vehicle, a camera of the advanced driver assistance system (ADAS) when the vehicle is equipped with ADAS, or a surround view monitor (SVM) camera when the vehicle is equipped with the SVM function. In addition, any camera can be used as long as it can be controlled by the processor 110 and captures the image of the surrounding environment of the vehicle.

[0097] The cameras that the processor 110 can control vary according to the type of the electric vehicle. Therefore, the storage unit 120 stores information about the cameras that the processor 110 can control and information about the directions in which the cameras can capture images. The processor 110 can capture the image including the charger by using the information stored in the storage unit 120.

[0098] When the position of the charger is in a blind spot that cannot be captured by the camera of the electric vehicle being charged, the processor 110 identifies the image including the charger among the past images captured when the vehicle enters the parking space for charging, and then sends the image to the driving information management server 201.

[0099] For this purpose, the processor 110 may use artificial intelligence image analysis technology capable of identifying the charger image in the image. This technology is not limited to a specific method. However, the artificial intelligence image analysis technology may be configured to extract a shape similar to the shape of the charger included in the past traditional charging station image information received from the driving information management server 201 from the image, and send it to the driving information management server 201 to be used as a new charging station image.

[0100] The processor 110 sends the charging station information including at least one of charging success / failure, charging speed, and charging time to the driving information management server 201 together with the captured image. By sending various types of information related to charging together with the image of the charger that actually performs charging, the driver who uses the charger later can determine the accurate status information of each charger.

[0101] For example, when the driver arrives at the charger and attempts to charge the electric vehicle but fails, he or she can send the information about the charging failure together with the charging station image of the charger to guide future users to avoid this charger and use another charger.

[0102] In addition, when charging is successful, detailed information related to the actual charging, such as the charging speed of the charger, can be sent so that a driver who will later use the charger can use this information to select a charging station and a charger.

[0103] The processor 110 sends information for identifying the arrived charging station to the driving information management server 201, receives the charging station image of the arrived charging station from the driving information management server 201, and outputs the charging station image of the arrived charging station. The charging station image can be an image selected from among images captured by the driving information management server 201 from multiple electric vehicles and sent.

[0104] In other words, the driving information management server 201 collects information previously received from electric vehicles using the corresponding charging station and provides the latest information containing accurate information to a driver who will later use the charging station, enabling the driver to utilize the latest information.

[0105] When the driving information management server 201 selects a charging station image to be used from among charging station images received from multiple electric vehicles, criteria for selection can be information such as the resolution of the image, the shooting time of the image, whether charging is successful, and whether the charger is accurately captured in the image.

[0106] Figure 2 FIG. is a block diagram showing the internal configuration of the driving information management server 201 according to various exemplary embodiments of the present disclosure.

[0107] The driving information management server 201 according to various exemplary embodiments of the present disclosure is a server provided with a central processing unit (CPU) and a memory, and may include an independent server or a cloud. The central processing unit includes a processor. The configuration of the driving information management server 201 is not limited as long as the driving information management server 201 can obtain a target remaining battery level by processing information received from the above-described driving information display device 101 through a wired or wireless communication network and send the target remaining battery level back to the driving information display device 101 through the communication network.

[0108] The driving information management server 201 of the present disclosure stores this information and processes operations required to generate charging station information (such as a charging station image) to be displayed on the driving information display device 101. Therefore, the description provided in combination with the driving information display device 101 can be applied to the driving information management server 201 without significant change.

[0109] As shown in the figure, the driving information management server 201 may include a connection establishment unit 210, a charging station information storage unit 220, and a charging station information sending unit 230. Each component can be manufactured in the form of a software module running within the server.

[0110] The connection establishment unit 210 establishes a connection with the driving information display devices 101 of multiple electric vehicles for information exchange. The connection establishment unit 210 establishes a connection with the communication unit 130 of the driving information display device 101 through a wired or wireless communication network, and is not limited to a specific type of communication.

[0111] The charging station information storage unit 220 stores the information for identifying charging stations and charging station images received from the driving information display devices 101 of multiple electric vehicles through the established connection. As previously combined Figure 1 As described, when the driver uses a charging station, the processor 110 of the driving information display device 101 captures an image including the charger. The charging station information storage unit 220 receives and stores the charging station images from multiple electric vehicles, thereby allowing the charging station images to be used in the driving information display device 101 of the electric vehicle that will later use the corresponding charging station. In order to identify and provide the charging station image of the actually used charging station, the information for identifying the charging station is stored in association with the charging station image.

[0112] The charging station information storage unit 220 receives the charging station information including at least one of charging success / failure, charging speed, and charging time and the captured charging station image, and stores them in association with the information for identifying the charging station. As described above, in order to share the latest status information about the charging station, the information about charging success / failure, charging speed, and charging time is received from the electric vehicle that is actually charging, and then these information are stored. Using these information, the driver who will later use the charging station can obtain accurate information about the status of each charger in the charging station and select the charging station and charger.

[0113] The charging station information storage unit 220 analyzes the received charging station image, and stores the charging station image only when the image contains a charging station and the image quality of the image is equal to or greater than a reference value. In order to check whether the image contains a charging station, it can be checked whether there is a region with the characteristics of a charger by comparing the image with the regular charging station images stored in the charging station information storage unit 220. In addition, in order to compare the image quality of the images, the resolution of the image can be identified. Various other techniques can be applied to analyze the image quality of the images.

[0114] By allowing the charging station information storage unit 220 to store only the charging station images with available quality as described above, more available images can be quickly selected when the charging station images are selected and sent.

[0115] The charging station information sending unit 230 selects one image from the stored charging station images based on the information for identifying the charging station received from the driving information display device of any one of the plurality of electric vehicles, and sends the selected charging station image to the driving information display device 101 that has sent the information for identifying the charging station.

[0116] The charging station information storage unit 220 stores, for each charging station, the charging station images sent from the electric vehicles that have used the charging station. Therefore, when the driving information display device 101 of the electric vehicle sends the information for identifying the charging station for outputting the charging station image, the charging station information sending unit 230 searches for the charging station image corresponding to the information for identifying the charging station, selects the best image from the found images, and sends the best image to the driving information display device 101.

[0117] In this case, the charging station information sending unit 230 selects the charging station image captured at the time of the most recent successful charging based on the stored charging station information. In this way, the image captured most recently by the electric vehicle that has actually been successfully charged can be sent, allowing the charging station image to be continuously updated with the latest image.

[0118] In addition, the charging station information sending unit 230 can use the analysis results of the resolution and quality of the charging station images to select the charging station images, and can use the analysis results of whether the parts representing the characteristics of the chargers in each image are accurately captured.

[0119] Figure 3 It is a diagram showing an example of the charging station information output from the driving information display device according to various exemplary embodiments of the present disclosure.

[0120] As shown in the figure, the charging station-related information output from the driving information display device 101 through the output unit 140 may include the charging station image displayed on the right side of the drawing and the charging station status information displayed on the left side.

[0121] The information displayed together with the charging station image may include various types of information, such as the charging station name, the charging station location, the manager contact information, the working hours, the price, and the date of the most recent successful charging. In addition, the number of chargers for each charging speed, the number of in-use chargers, and the number of unused chargers can also be separately identified.

[0122] The information about the number of in-use chargers may be information collected from each charging station. The information about the number of in-use chargers can be obtained from the electric vehicles currently using the corresponding charging station.

[0123] As shown in the figure, when the driver arrives at the charging station, he or she can check the image of the charging station and quickly find the charger within the space. In addition, when the charging station is included as a destination or a waypoint on the route and the image of the charging station is pre-displayed before starting the drive, the status of the charging station is checked through the image and the relevant information displayed on the left is also checked, and then it is selected whether to use the charging station. When it is selected not to use the charging station, another charging station can be recommended.

[0124] Figure 4 A diagram showing an example of using augmented reality to display charging station information in a driving information display device according to various exemplary embodiments of the present disclosure.

[0125] In an exemplary embodiment of the present disclosure, augmented reality technology can be applied in two ways to provide charging station information. The first way is to identify information such as the position of the charger in the image of the charging station to be displayed and output information about the charging station at the required position.

[0126] When multiple chargers are captured in the charging station image, as shown in the figure, the charger on the right is the charger that was successfully charged by another driver most recently and is thus determined to be available, while the charger on the left is the charger that another driver failed to successfully use for charging recently. The position of each charger can be identified within the image, and information indicating whether the charger is available can be superimposed at the identified position.

[0127] In addition to the information indicating whether the charger is available, by using augmented reality technology, additional relevant information such as the charging speed, charging time, and price can also be provided in addition to the position of each charger, allowing the driver to intuitively understand this information.

[0128] The second way is to determine the area corresponding to the charger included in the charging station image in the image captured by the camera of the electric vehicle and provide information about the charger, which is superimposed on this image captured in real time. Although the second way may require a large amount of computation because the position of the charger needs to be accurately identified in the image in real time, the driver can more intuitively determine the charger in front of him or her that he or she will use.

[0129] Figure 5 A diagram showing a method of capturing an image of a charging station according to the position of a charging port in a driving information display device according to various exemplary embodiments of the present disclosure.

[0130] As shown in the figure, for each type of electric vehicle, the position of the charging port can be different. In some cases, as Figure 5 shown in (a), the charging port is located at the front of the electric vehicle. In other cases, as Figure 5As shown in (b), the charging port is located on the side of the rear of the electric vehicle. There can be other situations.

[0131] The position of the camera that can accurately capture the image of the charging station including the charger during the charging of the electric vehicle varies according to the position of the charging port of the electric vehicle.

[0132] For example, in Figure 5 the case of (a), the vehicle needs to be parked facing the charger and then charged, so that the image of the charging station including the charger can only be captured using the front camera of the vehicle.

[0133] Conversely, when the charging port is located at the rear of the vehicle, as in Figure 5 the case of (b), the charger needs to be located behind the vehicle so that when using the rear camera of the vehicle, the image of the charging station including the charger can be captured.

[0134] For this purpose, the driving information display device 101 of each electric vehicle is configured to perform control to store information about the direction in which each available camera can capture an image, select the best camera that can accurately capture the image of the charger, and then capture the image.

[0135] When there are multiple cameras that can capture images in the same direction, an image with the highest resolution or best quality or an image including the charger can be selected from the images captured in that direction, and then that image can be used.

[0136] Figure 6 and Figure 7 are diagrams showing a method of capturing an image of the charging station when it is difficult to capture an image during the charging of an electric vehicle in a driving information display device according to various exemplary embodiments of the present disclosure.

[0137] As shown in the figure, when the charger is located on the side of the area where the electric vehicle is parked for charging, it may be difficult to capture an image using the front camera or the rear camera of the electric vehicle during charging. When the vehicle is equipped with AVM, there may be a camera that can capture the image of the side. However, in other cases, it is difficult to capture the image of the side, making it difficult to generate an image of the charging station.

[0138] Figure 6 shows the case where the charging port of the vehicle is located at the front of the vehicle, while Figure 7 shows the case where the charging port of the vehicle is located at the rear of the vehicle.

[0139] As Figure 6 shown, when the charger is located at a position spaced outward from one side of the front of the parking space, the electric vehicle needs to be parked and charged in such a way that its front faces the front of the parking space. As Figure 6As shown in (a) of , in this case, even when capturing an image using the front camera of the vehicle, the charger is not included in the image.

[0140] Therefore, in this case, as Figure 6 shown in (b) of , an image including the charger can be selected from the images captured during the process of entering the parking space before parking in the parking space, and then used as the charging station image.

[0141] For this purpose, when the vehicle enters the charging station area, the images captured by the camera can be stored at a predetermined time interval, and when the vehicle has parked and then the charging port of the electric vehicle is opened, an image including the charger can be selected from the most recently captured images.

[0142] To select an image including the charger, an operation can be performed to determine whether there is an area with the characteristics of a charger by comparing the image with the charging station images captured by another electric vehicle.

[0143] Figure 7 It shows a case where the charger is located at the same position as in Figure 6 but the charging port of the electric vehicle is located at its rear. In this case, the electric vehicle drives backward and then parks. As Figure 7 shown in (a) of , after parking is completed, even when capturing an image using the rear camera, the charger is not included in the image. Therefore, as Figure 7 shown in (b) of , an image including the charger is selected from the images captured during the process of driving backward and entering.

[0144] In the case where the charging port is located on the right side of the rear of the electric vehicle, different from the Figure 7 case, even when the charging port is located at the rear of the vehicle, there will be a situation where the vehicle drives forward. In this case, it may be desirable to use the images captured by the front camera during the process of entering the parking space, as in the Figure 6 case.

[0145] As described above, depending on the position of the charger and the position of the charging port of the electric vehicle, the optimal camera and capture time for capturing the charger may vary. Therefore, the driving information display device 101 checks the information about the position of the charging port of the vehicle and the position of the charger in the corresponding charging station, and is configured to determine the camera and viewing point for capturing the charger image based on this information.

[0146] The information about the position of each charger in each charging station can be pre-organized into a database in the driving information management server 201, and this information can be received from the driving information management server 201 and then used when entering the charging station.

[0147] Figure 8 A flowchart showing the operations of a driving information display device and a driving information management server according to various exemplary embodiments of the present disclosure.

[0148] The drawings schematically show the operations of the above-described driving information display device 101 and driving information management server 201. The part named "Vehicle" on the left side of the drawing shows the operation of the driving information display device 101 installed on an electric vehicle. The part named "Server" on the right side of the drawing shows the operation of the driving information management server 201.

[0149] As described above, the driving information display device 101 checks whether a charging station is included in the destination or waypoint on the route of the electric vehicle, and is configured to determine whether the vehicle has reached the charging station when the charging station is included in the destination or waypoint.

[0150] When it is determined that the electric vehicle has reached the charging station, an image is obtained through the vehicle's camera. As described above, among the vehicle's cameras, the camera that can accurately capture the charger is identified, and an image of the charging station is captured such that the charger can be included in the image of the charging station.

[0151] When actual charging is performed, after charging is completed, success / failure, charging time, and an image of the charging station are sent to the driving information management server 201. On the contrary, in the case where charging is not performed, the process ends. In this case, even when charging is not performed, an image of the charging station and information indicating that charging has failed can be sent so that subsequent drivers can check this.

[0152] The driving information management server 201 checks whether the charger is accurately captured in the image of the charging station received from the driving information display device 101, checks whether the information about charging has been accurately received, checks whether the image is the latest image, and finally checks whether the image quality of the image is equal to or greater than a reference value. Thereafter, the driving information management server 201 stores the image of the charging station and the charging information in a database.

[0153] In this case, the process of filtering the image can be performed before storage, as shown in the drawing. This filtering process can also be performed when selecting the image of the charging station to be sent after storing all the images received from the driving information display device 101. All these modifications fall within the scope of the present disclosure.

[0154] Figure 9 A flowchart showing the process of a driving information display method according to various exemplary embodiments of the present disclosure.

[0155] In an exemplary embodiment of the present disclosure, the driving information display method according to the exemplary embodiment of the present disclosure is a method executed by a driving information display device 101 provided with a processor 110 and a storage unit 120. The components described above in connection with the operation of the driving information display device 101 can be applied to the driving information display method without significant change. Therefore, by applying the foregoing description of the driving information display device 101, those skilled in the art can implement components that are not even specifically described in combination with the following driving information display method.

[0156] In the route analysis step S901, it is determined whether a charging station is included in the destination or a waypoint of the electric vehicle to which the driving information display device is attached.

[0157] In the charging station arrival determination step S902, it is determined whether the electric vehicle has arrived at the charging station included in the destination or the waypoint.

[0158] In the charging station information output step S903, it is checked whether the charging station image output condition is satisfied, and when the charging station image output condition is satisfied, the charging station image of the arrived charging station is output.

[0159] In this case, the charging station image output condition may be satisfied when the number of times the driver of the electric vehicle has visited the charging station in the past is less than a predetermined reference number, or may be satisfied when the time elapsed from the time point when the electric vehicle arrives at the charging station to the time point when the parking completion signal is received exceeds a predetermined reference time.

[0160] In the charging station image capture step S904, when the electric vehicle arrives at the charging station and the charging port of the electric vehicle is opened, an image is captured using a camera attached to the electric vehicle.

[0161] In the charging station image capture step S904, based on the information about the direction in which the charging port of the electric vehicle is located, one camera is selected from among a plurality of cameras attached to the electric vehicle, and an image is captured using the selected camera.

[0162] In the charging station image transmission step S905, the captured image is transmitted to the driving information management server together with the information for identifying the arrived charging station.

[0163] In the charging station image transmission step S905, the charging station information including at least one of charging success / failure, charging speed, and charging time is transmitted to the driving information management server together with the captured image.

[0164] In addition, in the charging station image sending step S905, information for identifying the arrived charging station is sent to the travel information management server. In the charging station image output step, a charging station image of the arrived charging station is received from the travel information management server and then output. In this case, the charging station image may be an image selected by the travel information management server from images captured and sent by multiple electric vehicles.

[0165] Figure 10 is a flowchart showing the process of a travel information management method according to various exemplary embodiments of the present disclosure.

[0166] In an exemplary embodiment of the present disclosure, the travel information management method according to the exemplary embodiment of the present disclosure is a method executed by a travel information management server 201 including a CPU and a memory. The components described above in connection with the operation of the travel information management server 201 can be applied to the travel information management method without significant change. Therefore, those skilled in the art can implement components that are not specifically described even by applying the above description of the travel information management server 201 in combination with the following travel information management method.

[0167] In the connection establishment step S1001, connections are established with the travel information display devices of multiple electric vehicles to exchange information.

[0168] In the charging station information storage step S1002, information for identifying a charging station and a charging station image received from the travel information display devices of multiple electric vehicles through the established connections are stored.

[0169] In this case, in the charging station information storage step S1002, charging station information including at least one of charging success / failure, charging speed, and charging time and the captured image are received and then stored in association with the information for identifying the charging station.

[0170] In the charging station information sending step S1003, based on the information for identifying a charging station received from the travel information display device of any one of the multiple electric vehicles, a charging station image is selected from the stored charging station images, and the charging station image is sent to the travel information display device that sent the information for identifying the charging station.

[0171] In the charging station information sending step S1003, the charging station image captured at the time of the most recent successful charging is selected based on the stored charging station information and then sent.

[0172] In addition, in the charging station information storage step S1003, the received charging station image is analyzed, and then the image is stored only when the charging station image contains a charging station and the image quality of the image is equal to or greater than a reference value.

[0173] The present disclosure can achieve the advantage of providing accurate and detailed information about an electric vehicle charging station.

[0174] The present disclosure can achieve the advantage of providing the latest image of an electric vehicle charging station, enabling a driver to accurately check the status of the charging station.
