Description

  The present invention relates to an in-vehicle navigation device and a navigation system capable of setting a destination using a mobile terminal device.

  In the in-vehicle navigation device, the user usually sets the destination using the input means of the in-vehicle navigation device. However, since the destination search operation and the destination setting operation using the in-vehicle navigation device are not performed frequently, it is very troublesome for a user who is not familiar with the operation. Further, in the case of a family trip or the like, the destination is often determined in the room at home, and it is troublesome for the user to bother to go to the car and perform the destination setting operation after determining the destination.

  Therefore, as described in Patent Document 1 and Patent Document 2, a destination is set using a mobile terminal device such as a smartphone that is used to operation, and the user holds the mobile terminal device and moves the vehicle. When you board, navigation automatically establishes communication between the in-vehicle navigation device and the mobile terminal device, acquires information on the destination from the mobile terminal device, and searches for the route to the destination and performs navigation The system is known.

  In this way, the navigation system that can set the destination using the mobile terminal device greatly eliminates the troublesome work of setting the destination directly on the vehicle-mounted navigation device side, thus greatly improving convenience. Will do.

JP 2010-54337 A Japanese Patent Laid-Open No. 2003-177027

  By the way, in the case of a family trip or the like, there is often a gap of several days to several weeks from the date when the destination is decided to the departure date that actually goes to the destination. Therefore, in such a navigation system, if the user gets on the car with the portable terminal device before the departure date, the vehicle will be used for in-vehicle use even though there is no plan to go to the relevant destination on that day. The route search and route guidance are performed on the navigation device side.

  In other words, for example, if a mobile terminal device is used on Sunday and a destination scheduled to be visited by a family on the next Sunday is set, the passenger does not intend when the user gets into the car on the next day commuting Regardless of the timing, the in-vehicle navigation device acquires information on the destination from the mobile terminal device, and performs route search and route guidance to the destination. Therefore, a troublesome operation of the in-vehicle navigation device is required for the passenger to stop the route search and the route guidance to the destination.

  In addition, it is also conceivable that the date of departure to the destination is set together with the setting of the destination using the portable terminal device, so that the in-vehicle navigation device performs route search and route guidance only on the departure date. However, even if it is the set departure date, it is actually possible that the user has a different schedule and the departure to the destination is stopped or delayed.

  Therefore, the present invention relates to an in-vehicle navigation device and a navigation system that can acquire destination information by communication via communication means for a portable terminal device that can set a destination at an unintended timing.

  According to the in-vehicle navigation device of the present invention, route guidance is not performed in the in-vehicle navigation device unless the passenger conditions are satisfied. Therefore, after the destination is set by the mobile terminal device, the actual departure date is reached. It is possible to reduce route guidance to unnecessary destinations that are performed during the period.

In addition, the navigation system of the present invention includes a portable terminal device having destination setting means for setting a destination, a communication means for acquiring information on the set destination from the portable terminal device, and the communication means. A navigation system comprising: an in-vehicle navigation device comprising: route search means for performing a route search based on the acquired information on the destination; and route guide means for guiding the route searched by the route search means. Because

The speaker 15 is used as an audio output means for outputting route guidance information by voice, or for outputting TV audio when the in-vehicle navigation device 10 includes a TV tuner (not shown).

  The in-vehicle camera 16 is used as an image acquisition unit that is an example of a passenger information acquisition unit described later. The in-vehicle camera 16 captures a face image of a passenger boarding the vehicle and obtains passenger information. The in-vehicle camera 16 is also used as passenger condition determination means described later. The in-vehicle camera 16 captures a face image of the passenger boarding the vehicle and determines whether or not the passenger traveling to the destination set as the passenger condition is actually on the vehicle.

  The in-vehicle camera 16 shown in FIG. 1 is shown as having a configuration in which the in-vehicle navigation device 10 includes a dedicated camera, but the in-vehicle navigation device 10 does not necessarily have to include the dedicated camera, and is connected via an external input terminal. It is possible to use an external camera. Specifically, a configuration using a camera for in-vehicle shooting of a drive recorder is more preferable. As for drive recorders, not only cameras for shooting outside the vehicle for recording the moment of an accident, but recently, products equipped with a camera for shooting inside the vehicle for reasons such as crime prevention are increasing. Therefore, the vehicle-mounted navigation device 10 can easily acquire the passenger information by using the in-vehicle shooting camera of the drive recorder having two cameras as the vehicle-mounted camera 16.

  The communication unit 17 is used as a communication unit for performing wireless communication with the mobile terminal device 50. This wireless communication is a short-distance communication means such as Bluetooth (registered trademark) (hereinafter referred to as Bluetooth) or infrared communication. The communication unit 17 may be not only a non-contact communication unit but also a wired communication unit such as a bus connection, but a non-contact communication unit is preferable because connection work by the user is required.

  Next, the portable terminal device 50 includes a data communication transceiver 51, a display 52, a touch panel 53, a speaker 54, a microphone 55, a communication unit 56, a CPU 57, a ROM 58, a RAM 59, a passenger database 60, and a connection bus 61. . The mobile terminal device 50 is an information device that can be carried by the user, such as a smartphone or a mobile phone.

  The data communication transmitting / receiving unit 51 transmits / receives information to / from an external server via the Internet, or transmits / receives voice information to / from a base station to perform a call with another mobile terminal device. It is used as a terminal communication means for

  The display 52 is used as terminal display means for displaying information acquired via the data communication transmitting / receiving unit 51 and displaying commands for performing various settings of the mobile terminal device 50. The display 52 displays map information acquired from an external server via the data communication transmitting / receiving unit 51, or displays an operation command when the user sets a destination based on the map information. Therefore, it is also used as a destination setting means.

  The touch panel 53 detects a pressed position of a command displayed on the display 52, and is used as a terminal input unit for various operations by the user. The touch panel 53 is also used as a destination setting means by detecting the pressing of a command when determining the destination.

  The speaker 54 is used as terminal audio output means for outputting audio data acquired via the data communication transmitting / receiving unit 51. The microphone 55 is used as terminal voice input means for inputting user's voice and surrounding voice. In addition, when the portable terminal device 50 can set a destination by voice input, the speaker 54 and the microphone 55 are also used as a destination setting unit.

  The communication unit 56 is used as a communication unit for performing wireless communication with the in-vehicle navigation device 10. This wireless communication is Bluetooth, infrared communication, or the like, similar to the communication unit 17 of the in-vehicle navigation device 10.

  The CPU 57, ROM 58, and RAM 59 constitute a control unit of the mobile terminal device 50. The CPU 57 is a central processing unit and performs various arithmetic processes. The ROM 58 stores a control program for the CPU 57 to perform various arithmetic processes. The RAM 59 is used as a work area when the CPU 57 performs various arithmetic processes.

  The passenger database 60 constitutes passenger information storage means for storing information on passengers acquired via the communication unit 56. The passenger database 60 may use a memory built in the portable terminal device 50 or may use an external server via the data communication transmitting / receiving unit 51.

  Next, the concept of the operation of the navigation system 1 of the present embodiment will be described with reference to FIG. First, the navigation system 1 uses the in-vehicle camera 16 of the in-vehicle navigation device 10 in the vehicle to photograph the face of the passenger in the vehicle, and acquires the face image information of each passenger (step 101).

  The acquisition of the face image information is performed by an image acquisition unit that is an example of a passenger information acquisition unit including the in-vehicle camera 16 and the CPU 18. Further, the photographing of the face of the passenger is automatically performed by the image acquisition means by a technique such as autofocus without requiring a photographing operation by the passenger. In addition, although the camera equipped with the portable information terminal 50 may be used instead of the vehicle-mounted camera 16 used as the image acquisition means, since the photographing operation by the user of the portable information terminal 50 is required, A configuration using the in-vehicle camera 16 is preferable.

  Next, the navigation system 1 transmits the face image information of each passenger to the mobile terminal device 50 of the passenger (in this example, the mother M) via the communication unit 17 of the in-vehicle navigation device 10, and the mobile terminal The face image information is stored in the passenger database 60 of the device 50 (step 102).

  The saving of the face image information is performed by a passenger information storage means including a passenger database 60 and a CPU 57 or the like. The passenger database 60 is not limited to a memory or the like built in the portable terminal device 50, and an external server on the Internet may be used via the data communication transmitting / receiving unit 51. By using an external server, the same passenger information can be shared with other portable terminal devices.

  Next, when the user searches for a destination or sets a destination using the mobile terminal device 50 at home, the navigation system 1 stores the set destination information in a built-in memory or the like. (Step 103).

  The destination setting by the user is performed by a destination setting means including a data communication transmitting / receiving unit 51 that acquires map information from an external server, a display 52 that displays the map information, a touch panel 53, a CPU 57, and the like. . The map information used for setting the destination may be the information stored in the memory built in the portable terminal device 50, but the map information is transmitted via the data communication transmitting / receiving unit 51. By acquiring the map information, it is possible to easily obtain map information that is always close to the latest state.

  Next, the navigation system 1 sets the destination in step 103 and, when the user sets a fellow passenger who intends to go to the destination together, the set passenger (in this example, the mother M and the child). S1 and child S2) are stored in a built-in memory or the like as passenger conditions (step 104).

  Passenger conditions are set by the user by means of a passenger database 60 in which the face image information of the passenger is stored, a display 52 that displays this face image information as shown in FIG. 2, and a position selected by the user. This is performed by a passenger condition setting unit configured by the touch panel 53 to be identified and the CPU 57 or the like.

  Next, in the navigation system 1, when a person carrying the portable terminal device 50 in the vehicle (a mother M in this example) gets on, the communication unit 17 of the in-vehicle navigation device 10 and the communication unit 56 of the portable terminal device 50 Is established, and the set destination information and passenger conditions are transmitted to the in-vehicle navigation device 10 (step 105).

  Next, the navigation system 1 captures the passenger's face in the vehicle via the vehicle-mounted camera 16 of the vehicle-mounted navigation device 10 in the vehicle, and the passenger is set under the passenger image and passenger conditions. It is determined whether or not the face image matches (step 106).

  Whether or not the passenger condition is met is determined by the CPU 18 or the like that performs a discrimination process between the in-vehicle camera 16 that captures the face of the passenger and the face image of the passenger that is set in the passenger condition. This is performed by a passenger condition determination means comprising:

  When the passenger's face image matches the passenger's face image set under the passenger conditions, the navigation system 1 searches for the route to the set destination, Based on the route guidance (step 107).

  The route search to the destination is performed by route search means including the information on the set destination, the map database 21 storing the map information, the CPU 18 and the like. The map information when the destination is set by the mobile terminal device 50 and the map information stored in the map database 21 of the in-vehicle navigation device 10 do not necessarily match. There is a possibility that the facility name of the designated destination does not exist in the map information of the map database 21. Even in such a case, if the position information of longitude and latitude is included as the set destination information, a route search can be performed based on the position information of latitude and longitude.

  In addition, the route guidance to the destination includes the GPS receiver 11 that acquires the current position information of the vehicle, the autonomous navigation sensor 12, the map database 21 in which the map information of the route being guided is stored, and the route being guided. This is performed by a route guidance means composed of a display 13 for displaying, a speaker 15 for performing guidance by voice, a CPU 18 and the like.

  As described above, the navigation system 1 sets the passenger condition together with the destination setting by the mobile terminal device 50, acquires the destination information and the passenger condition by the in-vehicle navigation device 10, and matches the passenger condition. The vehicle-mounted navigation device 10 performs the route guidance only when the vehicle is on.

  It is set when the navigation system 1 is configured to simply set the destination with the mobile terminal device 50, simply acquire the destination information with the in-vehicle navigation device 10, and perform route guidance with the in-vehicle navigation device 10. There is a possibility that route guidance is performed at a timing when it is not necessary to go to the destination.

  Specifically, when a destination for a family trip to be performed on the weekend is set, route guidance to the destination is not required until the weekend. Therefore, if the route guidance is performed until the weekend, a troublesome operation of stopping the route guidance becomes necessary. It is also conceivable that the departure date for the destination is set together with the destination setting, and the route conditions are given only on the corresponding departure date by acquiring the schedule conditions together with the destination information. However, when the departure to the set destination is canceled due to an abrupt schedule on the day, route guidance to this destination becomes unnecessary, and the user feels bothered when the route guidance is performed.

  Therefore, the navigation system 1 sets the passenger conditions together with the destination setting in the mobile terminal device 50, acquires the destination information and the passenger conditions on the in-vehicle navigation device 10 side, and matches the passenger conditions. By performing the route guidance with the in-vehicle navigation device 10 only when the vehicle is on, unnecessary route guidance is prevented from being performed.

  In other words, when a destination for a family trip on the weekend is set, the possibility of satisfying the passenger condition is very low when the car is used for commuting until the weekend. Therefore, it is difficult to meet the passenger conditions until the weekend, and the possibility of unnecessary route guidance to the destination is reduced. In addition, even if the departure to the destination is canceled due to an emergency on the day, the possibility of satisfying the passenger condition is low. Therefore, even when the departure date conditions are set together with the destination setting, it is difficult to meet the passenger conditions, and the possibility of unnecessary route guidance to the destination is reduced.

  Next, details of processing operations of the in-vehicle navigation device 10 and the mobile terminal device 50 in the navigation system 1 of the present embodiment will be described with reference to the flowcharts of FIGS. 3 to 7. FIG. 3 is a flowchart showing processing in the in-vehicle navigation device 10, and corresponds to the processing in step 101 and step 102 shown in FIG. FIG. 4 is a flowchart showing processing in the mobile terminal device 50, and is a flowchart corresponding to the processing in step 102 shown in FIG. FIG. 5 is a flowchart showing processing in the portable terminal device 50, and is a flowchart corresponding to the processing in step 103 and step 104 shown in FIG. FIG. 6 is a flowchart showing processing in the mobile terminal device 50, and is a flowchart corresponding to the processing in step 105 shown in FIG. FIG. 7 is a flowchart showing the processing in the in-vehicle navigation device 10, and corresponds to the processing of step 106 and step 107 shown in FIG.

  The vehicle-mounted navigation device 10 is powered on when the vehicle engine is started, and performs communication connection with the communication unit 56 of the portable terminal device 50 possessed by the passenger along a predetermined program. . Specifically, for example, the communication unit 17 searches for the mobile terminal device 50 that is a Bluetooth device and connects to the mobile terminal device 50.

  And the vehicle-mounted navigation apparatus 10 starts the passenger information acquisition process shown in FIG. First, the in-vehicle navigation device 10 establishes communication connection with the portable terminal device 50 (step 201), and the entire vehicle interior is imaged by the in-vehicle camera 16 (step 202).

  Next, the in-vehicle navigation device 10 counts the number of passengers who are in the vehicle based on the image taken by the in-vehicle camera 16 (step 203). The number of passengers is counted, for example, by counting the number of moving objects based on a plurality of image data obtained by photographing the entire interior of the vehicle, or counting the number of objects that match the contours of a human face. The image processing technique can be used.

  Next, the vehicle-mounted navigation device 10 determines whether or not the number of passengers counted in step 203 is one (step 204). If the number of passengers is one (NO in step 204), this operation is terminated. If the number of passengers is greater than one (YES in step 204), then in-vehicle navigation device 10 acquires a passenger's face image as passenger information (steps 205-208).

  Specifically, the in-vehicle camera 16 focuses on the face of the passenger and the face image is taken (step 206). Then, the photographed face image is temporarily stored in the RAM 20 or a built-in memory (step 207). The vehicle-mounted navigation device 10 performs such face image acquisition for each passenger. Then, when the face images for the number of passengers are acquired, the in-vehicle navigation device 10 transmits the face image information to the mobile terminal device 50 via the communication unit 17 (step 209), and acquires the passenger information. The process ends.

  The passenger information acquired here is information that can identify individual passengers. Therefore, it is not limited to the face image as in this embodiment. Accordingly, the passenger information may be the passenger's fingerprint information or the passenger's voice information in addition to the face image information. Moreover, since it is highly likely that almost everyone will have a mobile terminal device such as a mobile phone or a smartphone in the future, the passenger information may be ID information or phone number information of the mobile terminal device.

  In step 204, if there is only one passenger, it is unlikely that passenger conditions will be set after that, so this operation is terminated without acquiring a face image. Even in this case, the face image may be acquired. Further, if the passenger has been in the past, it is not necessary to transmit the same passenger's face image to the mobile terminal device 50 each time. Therefore, the in-vehicle navigation device 10 creates a database of face image information on the in-vehicle navigation device 10 side, and transmits information to the portable terminal device 50 only in the case of a face image that does not match a past passenger. It may be configured.

  Next, the portable terminal device 50 starts the passenger information storage process shown in FIG. First, the portable terminal device 50 performs communication connection with the in-vehicle navigation device 10 on the portable terminal device 50 side as well as step 201 (step 301). And the portable terminal device 50 acquires the information of the face image transmitted from the vehicle-mounted navigation device 10 in step 209 via the communication unit 56 (step 302). And the portable terminal device 50 preserve | saves the information of the acquired face image in the passenger database 60 (step 303), and complete | finishes a passenger information storage process.

  Next, the mobile terminal device 50 starts the destination setting process shown in FIG. 5 and the passenger condition setting process for setting a fellow passenger corresponding to the set destination. First, the mobile terminal device 50 operates so that the user can search for a destination (step 401). Specifically, the portable terminal device 50 acquires information on a facility corresponding to a place or genre designated by the user via the data transmission / reception unit 51 and displays this information on the display 52.

  Next, when the destination is determined by the user, the mobile terminal device 50 stores the set destination information in the RAM 59, the built-in memory, or the like (step 402).

  Next, the mobile terminal device 50 operates so that it is possible to set a schedule condition such as a departure date for the user to go to the set destination (step 403). Specifically, the mobile terminal device 50 operates such that a calendar or the like is displayed on the display 52 and the departure date can be designated by the touch panel 53. And the portable terminal device 50 preserve | saves the schedule conditions set by the user in RAM59 grade | etc.,. It should be noted that the setting of the schedule condition is not essential, and it is preferable that the schedule condition can be set arbitrarily.

  Next, the mobile terminal device 50 operates so as to be able to set passenger conditions when heading to the set destination (step 404). Specifically, the mobile terminal device 50 displays the passenger's face image stored in the passenger database 60 on the display 52 and designates the passenger's face image corresponding to the current destination on the touch panel 53. Works as you can. And the portable terminal device 50 preserve | saves the passenger conditions set by the user in RAM59 grade | etc., And complete | finishes a destination setting process and a passenger condition setting process.

  It should be noted that it is more preferable that the schedule condition in step 403 can set not only a date such as a departure date but also a time zone such as morning or afternoon, daytime or night. This is because, for example, even if all the passengers of the passenger conditions set in step 404 board on the departure date, all passengers go shopping in the morning and may depart to the destination from the afternoon. Even so, the destination may vary depending on the time of day.

  Next, the mobile terminal device 50 starts transmission processing of the set schedule conditions, passenger conditions, and destination information shown in FIG. First, when the mobile terminal device 50 is carried by a passenger and brought into the vehicle, the engine of the vehicle is started and the power of the in-vehicle navigation device 10 is turned on, the mobile terminal device 50 communicates with the in-vehicle navigation device 10. Are connected (step 501). Then, when the communication with the in-vehicle navigation device 10 is established, the portable terminal device 50 stores the schedule conditions, passenger conditions, destinations stored in the RAM 59, the built-in memory, etc. as in steps 502 to 504. Information is transmitted and the transmission process is terminated.

  Next, the vehicle-mounted navigation apparatus 10 starts the passenger condition determination process shown in FIG. 7, the route search process to the destination, and the route guidance process for starting guidance of the searched route. First, the in-vehicle navigation device 10 receives the schedule conditions, passenger conditions, and destination information transmitted from the mobile terminal device 50 (steps 601 to 602), and stores these conditions in the RAM 20 or the like.

  Next, the vehicle-mounted navigation device 10 determines whether or not the schedule condition acquired in Step 601 is met (Step 604). Whether or not the schedule condition is met is determined based on, for example, calendar information and a clock function built in the vehicle-mounted navigation device 10.

  And if the vehicle-mounted navigation apparatus 10 does not meet the schedule conditions (NO in step 604), these processes are terminated. On the other hand, if the in-vehicle navigation device 10 matches the schedule conditions (YES in step 604), it next determines whether or not the passenger conditions are met (step 605).

  Specifically, for example, the determination of whether or not the passenger condition is met is performed by, for example, taking a face image of the passenger in the vehicle using the in-vehicle camera 16 and determining the passenger's condition included in the passenger condition. This is done by comparing the face image with the face image of the actual passenger and determining whether or not they match. It should be noted that various known image processing techniques can be employed to determine whether or not they are the same person using such face images.

  If the in-vehicle navigation device 10 does not meet the passenger condition (NO in step 605), the processing ends. On the other hand, if the in-vehicle navigation device 10 matches the passenger condition (YES in step 605), the destination corresponding to the destination information acquired in step 603 is set as the current destination (step 606). .

  Next, the vehicle-mounted navigation device 10 performs a route search to the facility or place set as the current destination in step 606 (step 607). Specifically, using the link information of the road information included in the map information of the map database 21 and the node information, the route calculation cost is calculated using the Dijkstra method or a method equivalent thereto, and the calculated route calculation cost is small. The route search is performed by connecting the links. Note that a plurality of routes may be searched so that the user can select a favorite route from the plurality of routes.

  Then, the vehicle-mounted navigation device 10 ends the passenger condition determination process, the route search process to the destination, and the route guidance process for starting the guidance of the searched route by starting the guidance of the searched route. To do. That is, the vehicle-mounted navigation device 10 does not start route guidance unless the passenger conditions are met, and route guidance is performed when the passenger conditions are met. Note that the in-vehicle navigation device 10 may be configured to perform the destination setting process in step 606 and the route search process in step 607 before performing the process of determining whether or not the passenger condition in step 605 is met. .

  As described above, according to the navigation system 1 and the in-vehicle navigation device 10 of the present embodiment, the passenger terminal 50 sets the passenger condition together with the destination setting, and the in-vehicle navigation device 10 sets the destination. Information and passenger conditions are acquired, and the route guidance is started by the in-vehicle navigation device 10 only when the passenger conditions are met, so that it does not start immediately after setting the destination. In this case, it is possible to reduce the situation where unnecessary route guidance to the destination is performed until the departure date.

  Further, according to the navigation system 1 and the in-vehicle navigation device 10 of the present embodiment, the schedule conditions are set together with the destination setting in the mobile terminal device 50, and whether the in-vehicle navigation device 10 meets the schedule conditions. Since it is also determined whether or not, the situation in which unnecessary route guidance to the destination is performed until the departure date can be further reduced.

  Note that the schedule condition determination process for determining whether or not the schedule conditions are met is performed on the in-vehicle navigation device 10 side, but may be configured to be performed on the mobile terminal device 10 side. Specifically, in the transmission process of the mobile terminal device 10 shown in FIG. 6, it is determined whether or not the schedule condition is satisfied, and only the destination information that satisfies the schedule condition is included in the in-vehicle navigation device together with the passenger condition. 10 may be transmitted. For example, when a plurality of destinations are set, if all the destination information is transmitted to the in-vehicle navigation device 10, the processing load on the in-vehicle navigation device 10 side increases. With such a configuration, the load on the in-vehicle navigation device 10 side can be reduced.
