Abstract

<P>PROBLEM TO BE SOLVED: To enable an on-vehicle navigation device to prevent a user from forgetting a purpose in which the user calls at facilities without guiding a route up to a destination so as to pass desired facilities of the user. <P>SOLUTION: When a final destination and calling-at facilities are set by the user, a computer 30 determines whether one's own vehicle calls at any of the calling-at facilities on the basis of the state of one's own vehicle in the set calling-at facilities. The computer 30 gives the alarm in which the calling-at facilities at which the user does not call exist in the case that the calling-at facilities at which one's own vehicle does not call exist when a distance from the current position of one's own vehicle to the final destination is a first prescribed distance or less. Thereby the user is prevented from forgetting the purpose in which the user calls at the desired facilities without guiding the route up to the destination so as to pass the desired facilities of the users. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to an in-vehicle navigation device.

  2. Description of the Related Art Conventionally, there has been proposed an in-vehicle navigation device that can set a facility desired by a user as a transit point and search for a route to a destination so as to pass through the transit point. According to this in-vehicle navigation device, for example, when a destination is set, an item “Set a waypoint” and an item “Do not set a waypoint” are displayed on the display unit. When the “set via point” item is selected, a via point setting menu is displayed on the display unit. This waypoint setting menu includes “search by name”, “search by genre”, “search by phone number”, and the like. Any item in the waypoint setting menu is selected, and a search condition corresponding to the selected menu is input. A facility corresponding to the facility data that matches the input search condition is set as a transit point. Then, the route to the set destination is searched by a technique such as the Dijkstra method so as to pass through the set waypoint. Then, route guidance is performed according to the searched route.

  For example, a user may desire to drop in at a bookstore when going home from a company at work. In this case, in order to prevent the user from forgetting the purpose of stopping at the bookstore, the user uses the above-described conventional apparatus to pass through a specific bookstore, and to go to a destination via a specific bookstore. Set as. Then, the route from the company of work to the home is searched through the bookstore, and route guidance is performed according to the searched route.

  However, there is a high possibility that the user is familiar with the route from the company where he works to his home. For this reason, the user may feel annoyed when the conventional apparatus performs route guidance according to the route from the office of work to the home.

  The present invention has been made in view of the above-described points, and prevents a user from forgetting the purpose of stopping at a desired facility without performing route guidance to the destination so as to pass through the user's desired facility. It is an object of the present invention to provide an in-vehicle navigation device that can do this.

In order to achieve the above object, an in-vehicle navigation device according to claim 1,
Current position detection means for detecting the current position of the host vehicle;
Data storage means for storing map data relating to a road map and facility data relating to facilities on the road map;
Setting means for setting the final destination and the stop-off facility by the user based on the facility data;
A determination means for determining whether or not the host vehicle has not stopped at any of the set stop facilities based on the state of the host vehicle among the set stop facilities;
If the distance from the current position to the final destination is less than or equal to the first predetermined distance, and the determination means determines that the vehicle is not yet stopped by any of the stopping facilities, there is an unstopped stopping facility And warning means for warning.

  As described above, in the in-vehicle navigation device according to claim 1, when the final destination and the stop-off facility are set by the user, the stop-in facility is set based on the state of the own vehicle in the set stop-off facility. It is determined whether or not the host vehicle has stopped by any of them. When the distance from the current position of the host vehicle to the final destination is equal to or less than the first predetermined distance and there is a stop facility where the host vehicle is not stopped, the device stops the stop of the host vehicle. Warn that there is a facility. In this way, the user can remember that there is a facility to stop by before reaching the final destination. Thereby, it is possible to prevent the user from forgetting the purpose of stopping at the desired facility without performing route guidance to the destination so as to pass through the desired facility of the user.

  According to a second aspect of the present invention, once the warning means warns that there is an unstopped stop-off facility, the distance from the current position to the final destination is longer than the first predetermined distance. As long as the distance between the current position and the final destination is equal to or less than the first predetermined distance, it is preferable to cancel the warning that there is an unstopped stop-off facility. For example, the road around the final destination may be meandering. In this case, since there is a possibility that a warning that there is a stop-by facility where the host vehicle is not stopped may be given a plurality of times, the user may feel troublesome. For this reason, after the warning of the stop-off facility where the host vehicle does not stop, the device has a distance from the current position of the host vehicle to the final destination equal to or longer than the second predetermined distance that is longer than the first predetermined distance. As long as the distance between the current position and the final destination is equal to or less than the first predetermined distance, the warning of the stopping facility where the host vehicle has not stopped is stopped again.

  As described in claim 3, the current time acquisition means for acquiring the current time and the setting means cause the user to set a scheduled time to stop at the stopping facility in addition to the final destination and the stopping facility, and the warning means includes: When the difference between the set scheduled time and the acquired current time reaches the first predetermined time, it is possible to warn that there is a stopping facility to stop at the scheduled time. Thereby, it is possible to prevent the user from forgetting the purpose of visiting the desired stop-off facility at the scheduled time.

  According to a fourth aspect of the present invention, it is preferable that a display unit is provided, and the warning unit displays a list of stop-by facilities that have not been visited on the display unit. Thereby, the user can grasp a stop-in facility that has not stopped.

  According to a fifth aspect of the present invention, the determination means stores the stop facility storage means for storing the set stop facility and the arrival for determining whether or not the current position has arrived at the stop facility stored by the stop facility storage means. When it is determined by the determination means and the arrival determination means that the current position has arrived at the stopping facility, the counting means that counts the stagnation time that the current position is stagnant at the stopping facility, and the counted stagnation time is the second When the predetermined time is reached, the stop facility storage means has an erasure means for erasing the stop facility at which the current position has arrived, and based on whether the stop facility is stored in the stop facility storage means, It is preferable to determine whether or not the own vehicle has not stopped at any of the set stopping facilities. By doing in this way, it can be determined whether the own vehicle has stopped at any of the set stop facilities.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram illustrating a schematic configuration of an in-vehicle navigation device 100 according to the present embodiment. Hereinafter, the in-vehicle navigation device according to the present embodiment will be described in detail.

  The navigation device 100 includes a position detector 10, a digital road map database 20, a computer 30, a display unit 40, an operation switch group 50, an audio output unit 60, an audio input unit 70, a first storage device 80, and a second storage device. 81 and a VICS receiver 90.

  The computer 30 includes a known CPU, ROM, RAM, I / O, and a bus line for connecting these components. In the ROM, a program to be executed by the computer 30 is written, and a CPU or the like executes predetermined arithmetic processing according to this program.

  In addition, the RAM stores a final destination proximity flag indicating whether or not the host vehicle has approached the final destination described later. This final destination proximity flag is set to “1” when the straight line distance from the current position of the host vehicle to the final destination is 500 m or less, and the straight line from the current position of the host vehicle to the final destination. When the distance from the current position of the host vehicle to the final destination becomes 700 m or more after the distance becomes 500 m or less, the distance is reset to “0”.

  The position detector 10 includes a GPS receiver 11 for a global positioning system (GPS) that measures the position of a vehicle based on radio waves from a satellite, a geomagnetic sensor 12 for detecting the absolute direction of the vehicle, and a relative direction of the vehicle. Has a steering sensor 13 for detecting. Further, the position detector 10 includes a vehicle speed sensor 14 for detecting a travel distance from the travel speed of the vehicle.

  As described above, the position detector 10 includes the GPS receiver 11 for vehicle position measurement by radio wave navigation, and the geomagnetic sensor 12, the steering sensor 13, and the vehicle speed sensor 14 for vehicle position estimation by self-contained navigation. ing. Further, the radio navigation is not limited to the GPS, but, for example, a VICS optical beacon may be used. Further, in order to detect the relative orientation of the vehicle in the self-contained navigation, a gyro sensor or wheel speed sensors provided on the left and right wheels of the vehicle may be used instead of the steering sensor 13.

  The digital road map database 20 is a device for inputting digital map data including road data, background data, character data, facility data, and the like to the computer 30. The digital road map database 20 has an information storage medium 21 for storing digital map data. As the information storage medium 21, a CD-ROM or a DVD-ROM is generally used depending on the data amount. A card, a hard disk, or the like may be used.

  Here, the configuration of road data will be described. The road data is composed of data such as a link ID with a unique number for each road, link coordinate data, node coordinate data, road type data indicating a road type such as an expressway or a national road, and road width data. . The link in the road data is obtained by dividing each road on the map into a plurality of nodes by nodes indicating intersections, branching points, etc., and defining a link between the two nodes. The link coordinate data describes the start and end coordinates of this link. When a node is included in the middle of the link, the node coordinates are described in the node coordinate data. This road data is used to give the shape of the road when performing map matching processing in addition to displaying a map.

  The background data is data for displaying the facility shape, natural terrain, and the like to be displayed other than the road when the road map is displayed on the display unit 40. The character data is for displaying place names, facility names, road names, and the like on the road map, and is configured as data in which coordinates on the map corresponding to the display positions are associated.

The facility data is used for facility search, and is composed of data such as facility type, facility name, latitude / longitude coordinates, etc. The display unit 40 is configured by, for example, a liquid crystal display, and the display unit 40 The vehicle position mark corresponding to the current position of the vehicle and a road map around the vehicle generated by the map data input from the digital road map database 20 can be displayed on the screen.

  The operation switch group 50 includes, for example, a touch panel switch integrated with the display unit 40 or a mechanical switch provided around the display unit 40, and is used for various inputs.

  The voice output unit 60 includes a speaker or the like, and outputs a guidance voice when route guidance is being performed, or outputs a guidance related to an input voice at the time of voice recognition. The voice input unit 70 is composed of a microphone or the like, and takes in a voice uttered by the user and inputs it to the computer 30. The computer 30 performs a process for recognizing the input voice, and executes various controls based on the recognition result.

  In the first storage device 80, when the final destination is set, if it is a facility, the latitude / longitude coordinate data (x0, y0) in the facility data is stored. The first storage device 80 stores latitude / longitude coordinate data (x ′, y ′) corresponding to the position of the user's home in advance.

  In the second storage device 81, when a stop-in facility is set, the facility name in the facility data corresponding to the set stop-in facility is stored.

  The VICS receiver 90 receives information such as road traffic information distributed from the VICS center via beacons laid on the road and FM broadcast stations in various places, and sends information from the vehicle side to the outside as necessary. It is a device that transmits. The received information is processed by the computer 30. For example, traffic jam information, speed limit information, and the like are superimposed on the road map displayed on the display unit 40.

  In addition, in the in-vehicle navigation device 100 of the present embodiment, when the final destination and the stop-off facility are set, the final destination proximity flag stored in the RAM of the computer 30 is reset to “0”, and When the linear distance from the current position of the vehicle to the facility location of the final destination is 500 m or less, it is determined whether or not the host vehicle has stopped at any of the set stopping facilities. Then, the apparatus has a warning display function for displaying a list of the stopping facilities where the own vehicle has not stopped on the display unit 40 when it is determined that the own vehicle has not stopped at any of the stopping facilities. In addition, for example, a search function for searching for the position of a facility or the like from an address, a facility name, a telephone number, or the like input by the user is also provided.

  These functions are executed mainly by the computer 30 performing various arithmetic processes. That is, when the final destination and the stopping facility are input, the computer 30 searches the final destination and the stopping facility using the map data of the digital road map database 20. In addition, the computer 30 displays the own vehicle position mark indicating the position of the vehicle and the surrounding road map on the display unit 40, or changes the scale of the road map.

  Next, the warning display control process in the present embodiment will be described in detail with reference to the flowcharts of FIGS. FIG. 2 is a flowchart showing a main routine of the warning display control process, and FIG. 3 is a flowchart showing a stoppage determination process routine.

  First, in step S10 of FIG. 2, the current position of the vehicle is detected. At this time, the position data by the GPS receiver 11 is acquired in the same form as the coordinate data (latitude and longitude) of the road data described above. In addition, the geomagnetic sensor 12, the steering sensor 13, and the vehicle speed sensor 14 acquire data related to the traveling direction and travel distance of the host vehicle, and calculate the coordinate data of the current position based on the vehicle position calculated or determined in the past. Perform (calculation of coordinate data by self-contained navigation). The current position is basically obtained based on coordinate data calculated by self-contained navigation. However, when the position data by the GPS receiver 11 is acquired, the two are compared, and when the difference is equal to or greater than a predetermined distance, the position data by the GPS receiver 11 is adopted as the current position.

  In step S20, map data of the surrounding map including the current position of the vehicle is read from the digital road map database 20 and displayed on the display unit 40. In step S30, it is determined whether a warning display is set. Specifically, for example, a menu screen is displayed on the display unit 40, and it is determined whether or not the “warning display setting menu” item on the menu screen is selected. If it is determined that the “warning display setting menu” item has not been selected, the process ends. On the other hand, if it is determined that the “warning display setting menu” item is selected, the process proceeds to step S40.

  In step S40, the final destination is set. Specifically, for example, a final destination setting menu is displayed on the display unit 40. The final destination setting menu includes “search by name”, “search by address”, “search by phone number”, and the like. The user selects one of the final destination setting menus and inputs search conditions corresponding to the selected menu. For example, when the user selects “Search by phone number”, the phone number “000-123-4567” of the facility desired by the user is input as a search condition, and the computer 30 receives the input phone number “000”. The facility data with the telephone number matching “−123-4567” is searched. The facility corresponding to the retrieved facility data is set as the final destination. The latitude / longitude coordinate data (x0, y0) in the facility data corresponding to the set final destination is stored in the first storage device 80.

  In step S50, a stop-in facility is set. Specifically, for example, a stop facility setting menu is displayed on the display unit 40. This stop facility setting menu includes “search by name”, “search by address”, “search by phone number”, and the like, similar to the destination setting menu. As in step S40, any item in the stop-in facility setting menu is selected, and a search condition corresponding to the selected menu is input. A facility corresponding to the facility data that matches this search condition is set as a stop-by facility. The facility name in the facility data corresponding to the set stop-off facility is stored in the second storage device 81.

  In step S60, it is determined whether or not the vehicle is traveling. Specifically, for example, it is determined whether or not the vehicle speed detected based on the signal from the vehicle speed sensor 14 is 0 km / h. When it is determined that the vehicle speed is 0 km / h, the process proceeds to step S70. In step S70, a drop-in determination process is executed. This stoppage determination process will be described with reference to the flowchart of FIG.

  In the flowchart of FIG. 3, first, in step S210, it is determined whether or not the host vehicle has arrived at a facility corresponding to a stopping facility where the host vehicle has not stopped among the stopping facilities set in step S50. Specifically, for example, the computer 30 extracts facility data corresponding to the facility name stored in the second storage device 81 from the digital road map database 20. Then, the computer 30 detects the latitude / longitude coordinate data (xi, yi) (i = 1... N, n: the number of extracted facility data) in the extracted facility data and the position detector 10. It is determined whether or not the absolute value of the difference value from the coordinate data (x, y) at the current position is equal to or less than a predetermined value (a, b). If it is determined that the absolute value of the difference value is not less than or equal to the predetermined value (a, b), the stop determination process is terminated. On the other hand, when it is determined that the absolute value of the difference value is equal to or less than the predetermined value (a, b), the process proceeds to step S220.

  In step S220, the computer 30 starts or continues counting the stagnation time after the host vehicle reaches the stopping facility. In step S230, it is determined whether or not the stagnation time has reached a predetermined time (for example, 5 minutes). If it is determined that the stagnation time has not reached the predetermined time, the process proceeds to step S240.

  In step S240, it is determined whether or not the host vehicle has left the arrived stop-off facility. Specifically, for example, the difference between the latitude / longitude coordinate data (xi, yi) used for the determination in step S210 and the current position coordinate data (x, y) detected by the position detector 10. It is determined whether or not the absolute value of the value is greater than a predetermined value (a, b). When it is determined that the absolute value of the difference value is not greater than the predetermined value (a, b), the process returns to step S220. On the other hand, when it is determined that the absolute value of the difference value is greater than the predetermined value (a, b), the stop determination process is terminated.

  If it is determined in step S230 that the stagnation time has reached the predetermined time, the process proceeds to step S250. In step S <b> 250, the computer 30 deletes the facility name in the facility data corresponding to the visited facility that has arrived from the second storage device 81.

  Returning to the flowchart of FIG. 2, if it is determined in step S60 that the vehicle speed is not 0 km / h, the process proceeds to step S80. In step S80, it is determined whether or not the final destination proximity flag stored in the RAM of the computer 30 is set to “1”. If it is determined that the final destination proximity flag is not set to “1”, the process proceeds to step S90.

  In step S90, it is determined whether or not the linear distance from the current position detected in step S10 to the final destination is 500 m or less. If it is determined that the straight line distance is not less than 500 m, the standby state is maintained as it is. On the other hand, if it is determined that the linear distance is 500 m or less, the process proceeds to step S100.

  In step S100, it is determined whether or not the host vehicle has stopped at any of the set stopping facilities. Specifically, the computer 30 determines whether any of the set stop-off facilities is stored in the second storage device 81. By doing in this way, it can be determined whether the own vehicle has stopped at any of the set stop facilities.

  If it is determined in step S100 that any one of the set stop-off facilities is stored, the process proceeds to step S110. In step S <b> 11, for example, a first list warning screen 310 as shown in FIG. 4 is displayed on the display unit 40. In the example of FIG. 4, the first list warning screen 310 displays a message “Don't stop at the following stopping facility!”, And a list of stopping facilities that have not stopped at the bottom of the message. “Book Store B” and “Liquor Store Z” are displayed. Thereby, the user can grasp a stop-in facility that has not stopped.

  Note that the first list warning screen 310 disappears from the display unit 40 when the elapsed time from the display on the display unit 40 reaches a predetermined time (for example, 1 minute). The first list warning screen 310 also disappears from the display unit 40 when the “OK” item on the lower right side of the first list warning screen 310 is selected.

  If it is determined in step S100 that none of the set stop-by facilities are stored, the process proceeds to step S120. In step S120, the computer 30 sets the final destination proximity flag stored in the RAM to “1”. For example, the road around the final destination may be meandering. In this case, since there is a possibility that the list of the stopping facilities where the host vehicle has not stopped is displayed a plurality of times, the user may feel troublesome. For this reason, after displaying the list of stop-off facilities where the host vehicle has not stopped, the computer 30 again determines the current position as long as the distance from the current position of the host vehicle to the final destination is not more than 700 m. When the distance of the final destination is 500 m or less, the display of the list of the stopping facilities where the own vehicle has not stopped is stopped.

  If it is determined in step S80 that the final destination proximity flag is set to “1”, the process proceeds to step S130. In step S130, it is determined whether or not the linear distance from the current position detected in step S10 to the final destination is 700 m or more. If it is determined that the straight line distance is 700 m or more, the process proceeds to step S140.

  In step S140, the computer 30 resets the final destination proximity flag stored in the RAM to “0”.

  If it is determined in step S130 that the linear distance is not 700 m or longer, the process proceeds to step S150. In step S150, it is determined whether or not the host vehicle has reached the facility corresponding to the set final destination. Specifically, for example, latitude / longitude coordinate data (x0, y0) in the facility data corresponding to the final destination stored in the first storage device 80 and the current position detected by the position detector 10 It is determined whether or not the absolute value of the difference value from the coordinate data (x, y) is equal to or less than a predetermined value (a, b). When it is determined that the absolute value of the difference value is not less than or equal to the predetermined value (a, b), the process returns to step S80. On the other hand, when it is determined that the absolute value of the difference value is equal to or less than the predetermined value (a, b), the computer 30 stores the latitude / longitude coordinate data (x0, y0) stored in the first storage device 80. Erase. When the facility name in the facility data corresponding to the set stop-by facility is stored in the second storage device 81, the computer 30 deletes the facility name in the facility data. Then, the computer 30 ends the process.

  In step S40, the user's home is set as the final destination (only the latitude / longitude coordinate data (x ′, y ′) corresponding to the position of the user's home is stored in the first storage device 80). In step S150, the latitude / longitude coordinate data (x ′, y ′) corresponding to the position of the user's home stored in the first storage device 80 and the position detector 10 are detected. What is necessary is just to determine whether the absolute value of a difference value with the coordinate data (x, y) of the present position is below a predetermined value (a, b). Even when it is determined that the absolute value of the difference value is equal to or smaller than the predetermined value (a, b), the computer 30 corresponds to the position of the user's home stored in the first storage device 80. It is assumed that the latitude / longitude coordinate data (x ′, y ′) is not deleted.

  As described above, according to the present embodiment, when the final destination and the stop-off facility are set by the user, the stop-off facility is set to one of the stop-off facilities based on the state of the own vehicle. It is determined whether or not the host vehicle has stopped. When the distance from the current position of the host vehicle to the final destination is 500 m or less and the computer 30 has a stop facility where the host vehicle does not stop, there is a stop facility where the host vehicle does not stop. The warning can be performed. In this way, the user can remember that there is a facility to stop by before reaching the final destination. Thereby, it is possible to prevent the user from forgetting the purpose of stopping at the desired facility without performing route guidance to the destination so as to pass through the desired facility of the user.

  It should be noted that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, in the above-described embodiment, the example in which the user sets the final destination and the stopping facility has been described. However, in addition to the final destination and the stop-in facility, a scheduled time to stop at the stop-in facility may be set.

  Specifically, for example, when a scheduled time to stop by a stop-by facility is set, the second time is set so that the set scheduled time and the facility name in the facility data corresponding to the set stop-by facility correspond one-to-one. Is stored in the storage device 81. The computer 30 determines whether or not the difference between the scheduled time and the current time stored in the second storage device 81 reaches a predetermined time (for example, 1 hour). If it is determined that the predetermined time has been reached, for example, a second list warning screen 320 as shown in FIG. In the example of FIG. 5, the second list warning screen 320 displays a message “Please drop in at the following stopping facility at the following time!”, And below the message, “To Super C” , Stop at 17:00! ”Is displayed. Thereby, it is possible to prevent the user from forgetting the purpose of visiting the desired stop-off facility at the scheduled time.

  In the above-described embodiment, the final destination proximity flag stored in the RAM of the computer 30 is reset to “0”, and the linear distance from the current position of the host vehicle to the facility location of the final destination is The example which determines whether the own vehicle has stopped at any of the set stop facilities when it became 500 m or less was demonstrated. However, when the vehicle engine is turned on from off based on the operating state of the engine, it may be determined whether or not the host vehicle has stopped at any of the set stop facilities.

  Specifically, for example, an ignition SW (not shown) that outputs a signal for turning on / off the engine is connected to the computer 30, and a signal output from the ignition SW to the computer 30 is an off signal. It is determined whether or not the signal is changed from ON to ON. When it is determined that the signal is changed from the off signal to the on signal, the computer 30 determines whether or not the host vehicle has stopped at any of the set stopping facilities. When it is determined that the host vehicle has not stopped at any of the set stops, for example, the above-described first list warning screen 310 as shown in FIG. 4 is displayed on the display unit 40.

  Furthermore, in the above-described embodiment, an example in which a stop-by facility is set for each facility has been described. However, instead of a specific facility, the type of facility to stop by may be set as the stop facility.

  Specifically, for example, when a facility type is set as a stop-in facility, the computer 30 stores the set facility type in the second storage device 81. When it is determined that the vehicle speed of the host vehicle is 0 km / h, the computer 30 has a radius c (m) centered on the coordinate data (x, y) of the current position detected by the position detector 10. In the circle, the facility data corresponding to the facility type stored in the second storage device 81 is extracted from the digital road map database 20. When the facility data corresponding to the facility type stored in the second storage device 81 is extracted, the computer 30 counts the stagnation time at the stopping facility corresponding to the facility data. If it is determined that the counted stagnation time has reached a predetermined time, the computer 30 deletes the facility type corresponding to the stop-by facility from the second storage device 81.

  In the computer 30, the final destination proximity flag stored in the RAM is reset to "0", and the straight line distance from the current position of the host vehicle to the facility location of the final destination is 500 m or less. In this case, it is determined whether or not the host vehicle has stopped at any of the set stopping facilities. When it is determined that the host vehicle does not stop at any of the stopping facilities, a list of facility types stored in the second storage device 81 is displayed on the display unit 40.

It is a block diagram which shows schematic structure of the vehicle-mounted navigation apparatus 100 by this embodiment. It is a flowchart which shows the main routine of the warning display control process in this embodiment. It is a flowchart which shows the routine of the stop determination process in this embodiment.
