[0001] This application is a divisional application of an invention patent application with an application date of May 23, 2018, application number 201810500922.7, and invention name “Vehicle route guidance device, system and method based on mobile terminal”. Technical Field

[0002] The present disclosure relates to a vehicle route guidance device based on a mobile terminal, a system including the device and a method thereof, and more particularly, to a technology for sharing a route from a vehicle position discovered by a mobile terminal to a destination with a terminal of a vehicle. Background Art

[0003] In recent years, a map guidance service applied to a vehicle is combined in a vehicle to provide a driver with a driving route, traffic and life information, and games in real time.

[0004] A conventional map guidance service is implemented by installing an integrated or detachable navigation terminal in a vehicle, and when a driver directly inputs a destination through a touch screen, the navigation terminal generates a route.

[0005] However, in order to update the program, the navigation terminal installed in the vehicle must be detached from the vehicle.

[0006] Therefore, there is a need for a technology for guiding a route through a navigation application of a mobile terminal by installing the navigation application in the mobile terminal which can be conveniently carried.

[0007] However, since this technology requires a separate holder for holding the mobile terminal in the vehicle, a technology for combining a route found in the mobile terminal with the terminal of the vehicle is needed. Summary of the invention

[0008] The present disclosure is conceived to solve the above-mentioned problems of the prior art, and the present disclosure provides a vehicle route guidance device based on a mobile terminal, a system including the device and a method thereof, through which the vehicle route guidance device can guide the driver to the best route by allowing the vehicle's terminal to share the route and destination pre-discovered by the mobile terminal.

[0009] The technical objectives of the present disclosure are not limited to the above-mentioned technical objectives, and other unmentioned technical objectives will become apparent to those skilled in the art from the following description.

[0046] The present disclosure discloses a technology for guiding the driver to the best route by receiving the route and destination pre-discovered by the mobile terminal from the mobile terminal by the vehicle terminal, thereby improving the convenience of the driver. To achieve this, a configuration is disclosed for generating GPS-based route information based on GPS information to effectively send the route information generated by the mobile terminal to the vehicle terminal through a telematics multimedia system (TMS) server. Further, in the present disclosure, the route includes route information from a departure point to a destination.

[0047] In the following, reference will be made to Figures 1 to 9 Exemplary embodiments of the present disclosure are described in detail.

[0048] Figure 1 is a diagram of a vehicle route guidance system based on a mobile terminal according to an embodiment of the present disclosure. Figure 2 is a block diagram of a terminal of a vehicle according to an embodiment of the present disclosure. Figure 3 is a block diagram of a mobile terminal according to an embodiment of the present disclosure.

[0049] Reference Figure 1 , a vehicle route guidance system based on a mobile terminal according to an embodiment of the present disclosure includes a vehicle terminal 100 installed in a vehicle, a TMS server 200 , a traffic information server 300 , and a mobile terminal 400 .

[0050] The vehicle terminal 100 may search for a route from a departure point to a destination, may consider traffic information received from the traffic information server 300 while searching for the route, and may share the departure point or destination information with the TMS server 200. Further, the vehicle terminal 100 may identify the location of the vehicle through a GPS receiver (not shown) or receive a parking location from the TMS server 200 to determine the destination information, and may use the destination information directly input by the user or the destination information received through the TMS server 200. Then, the destination information received through the TMS server 200 may be information associated with the TMS server 200 through the mobile terminal 400. The vehicle terminal 100 may include a navigation device, an audio, video and navigation (AVN) system, and a telematics terminal installed in the vehicle.

[0051] Reference Figure 2 The vehicle terminal 100 includes an input device 110 , a communication device 120 , a display 130 , a memory 140 and a processor 150 .

[0052] The destination may be input from the user to the input device 110, or one of the one or more routes may be selected through the input device 110. The input device 110 may be implemented by a keyboard, a dome switch, a touch pad (constant pressure type / static), a jog wheel (adjustment knob), a jog switch, or a touch pad.

[0053] The communication device 120 communicates with the TMS server 200 and the traffic information server 300. To achieve this, the communication device 120 may include various communication units including a mobile communication unit, a broadcast receiving unit such as a DMB module or a DVB-H module, a short-range communication unit, a ZigBee module such as a Bluetooth module or an NEC module, and a Wi-Fie communication unit.

[0054] The display 130 displays the road guidance screen by displaying the found route information or the route information received from the mobile terminal 400 on the screen to be regenerated. The display 130 may include at least one of a liquid crystal display (LCD), a thin film transistor (TFT) LCD, a light emitting diode (LED), an organic LED, an active matrix OLED (AMOLED), a flexible display, a curved display, and a 3D display. Among them, some displays may be implemented by transparent displays, which are configured in a transparent or light-transmitting manner so that the outside is visible. Further, the display 130 may be provided as a touch screen, which includes a touch pad to be used as an input device as well as an output device.

[0055] The memory 140 stores the discovered route information or the route information to be regenerated on the screen received from the mobile terminal 400. Then, the route information may include the travel time to the destination. The memory 140 may include a memory such as a flash memory type, a hard disk type, a micro type, or a card type (e.g., a secure digital (SD) card or an extreme digital (XD) card), and a storage medium of at least one of the memories such as a random access memory (RAM), a static RAM (SRM), a read-only memory (ROM), a programmable ROM (PROM), an electrically erasable PROM (EEPROM), a magnetic RAM (MRAM), a magnetic disk, and an optical disk.

[0056] The processor 150 searches for a route from the departure point to the destination and determines the best route by comparing the route information received from the mobile terminal 400. To achieve this, the processor 150 has an associated non-transitory memory storing software instructions that, when executed by the processor 150, provide the functionality of the controller 151, the synchronization module 152, the route search module 153, the route regeneration module 154, and the route determination module 155. The processor 150 may take the form of one or more processors and an associated memory storing program instructions.

[0057] The controller 151 of the processor 150 controls to display route information received from the mobile terminal 400 and route information found by the route search module 153 so that the user can select route information. Further, the controller 151 controls the overall operation of the elements and may include an electronic control unit (ECU).

[0058] The synchronization module 152 of the processor 150 may synchronize the route information discovered and generated by the mobile terminal 400 with the destination. That is, the synchronization module 152 may apply the destination or the route information received from the mobile terminal to the vehicle terminal 100.

[0059] The route search module 153 of the processor 150 may search for a route based on the destination and the traffic information. Then, the route search module 153 may reflect the traffic information received from the traffic information server 300.

[0060] The route regeneration module 154 of the processor 150 may regenerate the route section information from the departure point to the destination based on the GPS route information generated by the mobile terminal 400. Then, since the GPS route information generated by the mobile terminal 400 includes GPS information of each interval rather than the entire information of the path from the departure point to the destination, the route regeneration module 154 regenerates the route section information by using the GPS information and the map information, thereby displaying the section information.

[0061] The route determination module 155 of the processor 150 may determine the best route by comparing the route information found by the route search module 153 and the route information found by the mobile terminal 400 and received by the route determination module 155. That is, the route determination module 155 may determine a route with a shorter travel time as the best route by comparing the travel time to the destination in the route information received from the mobile terminal 400 and the travel time to the destination in the route information found by the route search module 153.

[0062] Reference Figure 1 , the TMS server 200 stores and manages the destination information registered in the vehicle terminal 100 or the mobile terminal 400, and stores the parking position information of the vehicle by communicating with the vehicle.

[0063] The traffic information server 300 collects traffic information from vehicles or road-side signal transmitting / receiving devices in real time, stores the traffic information, and provides real-time traffic information to the vehicle terminal 100 or the mobile terminal 400 when the vehicle terminal 100 or the mobile terminal 400 makes a request.

[0064] The mobile terminal 400 is a portable terminal of the user, which can be located inside or outside the vehicle, so that the route from the departure point to the destination can be searched inside or outside the vehicle. Then, the information about the departure point or destination can be directly input by the user, or the destination information shared by the vehicle terminal 100 through the TMS server 200 can be shared. Further, the mobile terminal 400 can receive traffic information from the traffic information server 300 during the search for the route, and can search for the route while reflecting the traffic information. Further, the mobile terminal 400 can search for the route after the user selects the departure location and departure time. GPS-based route information is generated based on the discovered and generated route information, and the final GPS-based route information is generated based on the form of the driving road, and is provided to the vehicle terminal 100 through the TMS server 200.

[0065] The mobile terminal 400 may include a smart phone, a tablet personal computer (PC), a mobile phone, a video phone, an e-book reader, a netbook computer, a personal digital assistant (PDA), a portable multimedia player (PMP), a mobile communication terminal, and an electronic notebook, and may include all devices in which a navigation application may be installed. Further, a vehicle-related application associated with the vehicle terminal 100 is installed in the mobile terminal 400. The vehicle-related application may be downloaded via wireless communication or the Internet, and may be automatically installed after downloading.

[0066] refer to Figure 3, the mobile terminal 400 may include an input device 410 , a communication device 420 , a display 430 , a memory 440 , and a processor 450 .

[0067] The input device 410 may receive a destination from a user.

[0068] The communication device 420 communicates with the TMS server 200 and the traffic information server 300 .

[0069] The display 430 may display the discovered route information.

[0070] The memory 440 may store the discovered route information.

[0071] The processor 450 shares the destination of the vehicle terminal 100 through the TMS server 200, or searches for a route to the destination by using the destination input by the user, generates GPS route information including GPS information in the found route, and shares the generated GPS route information with the vehicle terminal 100 through the TMS server 200.

[0072] To accomplish this, processor 450 has associated non-transitory memory that stores software instructions that, when executed by processor 450, provide the functionality of controller 451, location determination module 452, route search module 453, and route generation module 454. Processor 450 may take the form of one or more processors and associated memory that stores program instructions.

[0073] The controller 451 of the processor 450 controls the overall operation of the elements.

[0074] The location determination module 452 of the processor 450 may determine its location information, and may receive the location information from a GPS receiver (not shown) or a location sensor (not shown).

[0075] The route search module 453 of the processor 450 can search for a route to the destination input by the user while acquiring the location information determined by the location determination module 452 or the parking location information received from the TMS server 200 , and can search for a route by applying traffic information received from the traffic information server 300 .

[0076] The route generation module 454 of the processor 450 generates route segment information by using the discovered route information, and generates GPS-based route information according to the route segment information. Figure 4A is an exemplary view of route information generated by a mobile terminal according to an embodiment of the present disclosure. Figure 4B is an exemplary view of GPS-based route information obtained by converting route information in a mobile terminal according to an embodiment of the present disclosure. Figure 4C is an exemplary view of GPS route information optimized by a mobile terminal according to an embodiment of the present disclosure. Figure 4D is an exemplary view of route information resynthesized by a terminal of a vehicle according to an embodiment of the present disclosure.

[0077] Reference Figure 4A The route link information generated by the route generation module 454 includes route information from the departure point to the destination, and refers to Figure 4B The GPS-based route information includes GPS information of each interval of route information from a departure point to a destination.

[0078] Further, the route generation module 454 may generate GPS information of each first interval in the route from the departure point to the destination, and the route information based on GPS may include GPS information of each first interval. That is, the route generation module 454 may set the first interval to be larger as the length of the route from the departure point to the destination becomes longer. Figure 4C For example, when the total distance of the route from the departure point to the destination is 10km or less, GPS information can be extracted at intervals of 1km and GPS route information can be generated. As the total distance of the route becomes longer, the interval of GPS information becomes larger, and when the total distance of the route is 50km, the interval can be 5km, and when extracting GPS information to generate GPS route information, when the total distance of the route is 100km, the interval can be 10km.

[0079] The route generation module 454 may generate GPS information of each second interval in the partial area according to the form of the driving road on the generated GPS-based route information including the GPS information of the first interval, so as to generate the final GPS-based route information. Then, the form of the driving road may include at least one of a linear driving road, an entrance road, or a left or right turning road.

[0080] When the driving road is a linear driving road, it may include an expressway, an ordinary road, and a narrow road, and the second interval may be set to become smaller in the order of the expressway, the ordinary road, and the narrow road. For example, in the case of an expressway, the route information based on GPS includes GPS information with a maximum interval of 100 kilometers, in the case of an ordinary road, the route information based on GPS includes GPS information with a maximum interval of 80, 60, or 30 kilometers, and in the case of a narrow road, the route information based on GPS includes GPS information with a maximum interval of 10 kilometers. Then, the interval may be different according to the maximum speed of the road.

[0081] When the generated GPS-based route information including the GPS information of each first interval includes one of the entrance road or the left and right turning roads, the route generation module 454 may set the second interval to be smaller than the specific interval. For example, the GPS-based route information may be generated as GPS information of each interval of 1 km at two points before and after the vehicle enters the expressway, and GPS information of each interval of 1 km at points on or before and after the intersection of ordinary roads.

[0082] The route generation module 454 can primarily generate GPS route information by extracting GPS information at each specific interval (first interval) according to the form of the route (highway, ordinary road, narrow road, entrance road or intersection), and secondarily generate GPS route information by extracting GPS information at each specific interval (second interval), thereby preventing data transmission efficiency problems by sharing only the minimum route information required to regenerate the route in the vehicle terminal 100 with the vehicle terminal 100.

[0083] like Figure 4D As shown, the final GPS-based route information generated in this way can be regenerated by the vehicle terminal 100. That is, the vehicle terminal 100 can receive Figure 4C The final GPS-based route information can be obtained by using map information including Figure 4A and Figure 4D In this way, when all route information is transmitted after the mobile terminal 400 generates GPS-based route information and shares the generated GPS-based route information with the vehicle terminal 100, it is possible to prevent data transmission efficiency from being reduced.

[0084] In this way, according to the present disclosure, since the route information previously discovered by the mobile terminal 400 can be shared with the vehicle terminal 100, and the vehicle terminal 100 compares the route information shared with the mobile terminal 400 and the route information discovered by the vehicle terminal 100, the optimal route can be provided to the driver.

[0085] Below, we will refer to Figure 5 A vehicle route guidance method based on a mobile terminal according to an embodiment of the present disclosure is described in detail. Figure 5 is a flow chart showing a vehicle route guidance method based on a mobile terminal according to an embodiment of the present disclosure.

[0086] Fig. 6A is an exemplary view of a destination search screen of a mobile terminal according to an embodiment of the present disclosure. Figure 6B is an exemplary view of a screen for selecting a start location in a mobile terminal according to an embodiment of the present disclosure. Figure 7are exemplary views illustrating a route guided by a mobile terminal according to an embodiment of the present disclosure. Figure 8 is an exemplary view of displaying a route guided by a mobile terminal and a route discovered by a terminal of a vehicle on a terminal of a vehicle according to an embodiment of the present disclosure.

[0087] Reference Figure 5 , if the vehicle terminal 100 receives a destination from the user (step S101), the destination may be synchronized with the mobile terminal 400 through the TMS server 200 (step S102). Then, the mobile terminal 400 may directly receive the destination from the user. Fig. 6A , the mobile terminal 400 according to an embodiment of the present disclosure displays a screen for selecting whether to select a destination registered by the vehicle terminal 100 or a destination directly input by a user of the mobile terminal 400 . Figure 6B is an exemplary view of a screen for selecting whether the mobile terminal 400 according to an embodiment of the present disclosure will select the current location of the mobile terminal 400 or select the parking location received from the TMS server 200 as the departure location.

[0088] Subsequently, the mobile terminal 400 inquires about the vehicle information shared with the corresponding destination (step S103), receives the traffic information from the traffic information server 300 (step S104), and searches for a route based on the traffic information by using the current location of the mobile terminal or the parking location of the vehicle received from the TMS server 200 (step S105). Then, the route based on the traffic information is as follows: Figure 4A shown.

[0089] Afterwards, the mobile terminal 400 generates GPS-based route information according to the discovered route information (step S106), and sends the GPS-based route information (route A) to the vehicle terminal 100 through the TMS server 200 (step S107). Then, the GPS-based route information can be Figure 4B or Figure 4C As shown.

[0090] Therefore, the vehicle terminal 100 synthesizes the route section information again by using the GPS-based route information received from the mobile terminal 400 through the TMS server 200 (step S108). Then, the vehicle terminal 100 can synthesize the route by using the GPS information and the map information of the GPS-based route information, and the re-synthesized route section information is as follows: Figure 4D Then, Figure 4D The re-synchronized route segment information in is the same as the route segment information generated by the mobile terminal 400.

[0091] Thereafter, the vehicle terminal 100 receives traffic information from the traffic information server 300 (step S109), searches for a route (route B) based on the traffic information (step S110), and compares the route information (route A) shared with the mobile terminal 400 and the route information (route B) discovered by the vehicle terminal 100, and suggests an optimal route (step S111). That is, the travel time of route A and the travel time of route B can be compared to determine the route with a shorter travel time as the optimal route.

[0092] Figure 7 The screen of the vehicle terminal is illustrated, in which the travel time of route A provided by the mobile terminal 400 is shorter than the travel time of route B, and the vehicle terminal 100 inquires whether the road will be guided via route A. Figure 8 This is an exemplary view of a screen for allowing the driver to select route A or route B by densely displaying route B② as the optimal route and displaying route A together when the travel time of route A① is greater than the travel time of route B.

[0093] As such, according to the present disclosure, since route information previously discovered by the mobile terminal 400 can be shared with the vehicle terminal 100 and the vehicle terminal 100 compares the route information shared with the mobile terminal 400 and the route information discovered by the vehicle terminal 100, the best route can be provided to the driver.

[0094] Fig. 9 is a block diagram of a computer system to which a vehicle route guidance method according to an embodiment of the present disclosure is applied.

[0095] refer to Fig. 9 , the computing system 1000 may include at least one processor 1100 , a memory 1300 , a user interface input device 1400 , a user interface output device 1500 , a storage 1600 , and a network interface 1700 connected via a bus 1200 .

[0096] The processor 1100 may be a central processing unit (CPU) or a semiconductor device that processes instructions stored in the memory 1300 and / or the storage 1600. The memory 1300 and the storage 1600 may include various volatile or non-volatile storage media. For example, the memory 1300 may include a read-only memory (ROM) and a random access memory (RAM).

[0097] Therefore, the steps of the method or algorithm described in conjunction with the embodiments of the present disclosure may be directly implemented by hardware, software modules, or a combination thereof executed by the processor 1100. The software module may reside in a storage medium (i.e., memory 1300 and / or storage 1600), such as RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, a hard disk, a removable disk, or a CD-ROM.

[0098] An exemplary storage medium is coupled to the processor 1100, and the processor 1100 can read information from the storage medium and can write information in the storage medium. In another method, the storage medium can be integrated with the processor 1100. The processor and the storage medium can reside in an application specific integrated circuit (ASIC). The ASIC can reside in a user terminal. In another method, the processor and the storage medium can reside in a user terminal as a single component.

[0099] The present disclosure may improve the convenience of the driver by guiding the driver to an optimal route by receiving a route pre-discovered by a mobile terminal and receiving a destination from the mobile terminal by a vehicle terminal.
