  The present invention relates to a navigation device for a vehicle, and more particularly to a navigation device that presents information of interest to an occupant.

  In order to improve the convenience of the navigation device that guides the route from the departure point to the destination, it is possible to receive various tourist guidance and facility information from the information distribution center through the communication line. The driver can determine the destination with reference to these pieces of information, and can set the destination in the navigation device by operating the switch button or the like of the input unit.

However, since information that can be obtained from the information distribution center is general information for an unspecified number of people and includes information that is unnecessary for the user, for example, Japanese Patent Laid-Open No. 2004-2011149 discloses the user's information. An apparatus has been proposed in which user information such as interests and needs is created from travel history and search history in a past trip, information corresponding to the user information is selected and distributed from the information distribution center. .
JP 2004-2011149 A

However, even in the case of Japanese Patent Application Laid-Open No. 2004-2011149, only information on genres that the user has been interested in in the past is provided, and there are many things that are of general interest as the user. In this trip while driving, information on a particular genre that has been particularly interested in is not always available.
Therefore, in view of the above problems, the present invention provides a vehicle navigation apparatus that is provided with information on the genre that the driver has been interested in during the current traveling in a timely manner and has improved convenience. Objective.

  For this reason, the navigation device of the present invention specifies a camera that images the occupant's head, an image processing unit that detects the sight line direction of the occupant from the image signal of the camera, and an external object that is in the sight line direction as a target of attention. An attention target specifying means, a genre determination means for extracting a genre that the occupant is interested in from the attention object in the current trip, and an interest information presentation means for presenting information on the genre extracted by the genre determination means did.

Since the information of the genre determined based on the attention object visually recognized by the occupant during the current trip is provided, the information of interest at the present time is selected and provided in a timely manner.
This improves convenience, for example, a location related to information of current interest can be easily set as a destination.

Hereinafter, embodiments of the present invention will be described in detail.
FIG. 1 is a block diagram showing the configuration of the embodiment.
As a basic configuration, the navigation device includes, as a basic configuration, a controller 10, a GPS receiver 20 for detecting the current position of the vehicle, a speed sensor 21 and a gyro sensor 22, a map information storage unit 29 for storing map data information, and a manual input operation. A traffic information acquisition unit 23 for acquiring road traffic information (for example, VICS information such as traffic jam information and construction information), a display 40, a speaker 31, a communication unit 32, a work storage unit 30 and the like. Connected and configured.

The communication unit 32 can be connected to the information distribution center 34 via the communication line 33. The information distribution center 34 stores facility information 36 such as sightseeing guides and buildings classified by genre and stored together with the map data 35. Such information can be obtained by a request via the communication unit 32.
As a communication terminal for connecting the communication unit 32 and the communication line 33, although not particularly shown, a mobile phone or an in-vehicle phone can be used.

The map data information in the map information storage unit 29 includes information about roads including the number of lanes at each point, as well as facilities around the roads, buildings classified by genre, and the like with three-dimensional data. The road information also includes statistical traffic information such as traffic jams.
The GPS receiver 20 receives radio waves from positioning satellites and outputs position signals.
The speed sensor 21 detects the speed of the vehicle in order to obtain the moving distance of the vehicle, and the gyro sensor 22 detects the moving direction.

In the present embodiment, the controller 10 further includes a camera 24 that images the driver, a radar 27 that detects an inter-vehicle distance from another vehicle on the road, a seat position sensor 25 at the driver's seat, and a vehicle such as a TV / audio. A device operation detection unit 28 is connected.
An input / output interface for the controller 10 is not shown.

FIG. 2 shows a layout around the driver's seat.
A display 40 is arranged at the center in the left-right direction of the instrument panel 1 in which the meter 2 is arranged in front of the driver's seat, and the buttons of the input unit 26 are arranged along the lower side of the display screen.
The input unit 26 can take a form such as a touch panel or a keyboard (not shown) in addition to the switch button, and can perform an input operation such as destination setting as described above.
A camera is installed on the top or ceiling of the front window 3 toward the driver's seat.
The console unit 4 below the display 40 is provided with an operation unit 5 of an air conditioner as an in-vehicle device, an audio 6 and the like.

As shown in FIG. 3, the controller 10 includes a current position detection unit 11, a destination setting unit 12, a route search unit 13, and a route / information output unit 14. FIG. 3 shows only main elements outside the controller.
The current position detection unit 11 obtains a moving position from a specific point from the vehicle speed and the moving direction by the speed sensor 21 and the gyro sensor 22, and complements the moving position and the position signal from the GPS receiver 20 with each other. Detect current position.
The current position detection unit 11 can identify up to which lane on the road the current position of the vehicle with reference to the map data in the map information storage unit 29.

The destination setting unit 12 sets a destination through the operation of the input unit 26.
The route search unit 13 is based on the set destination, information on the current position from the current position detection unit 11, map data from the map information storage unit 29, road traffic information obtained from the traffic information acquisition unit 23, and the like. Find the best route to your destination.
The route / information output unit 14 outputs the optimum route obtained by the route search unit 13, road traffic information, various information along the route, etc. together with a map to be displayed on the display 40, or displays appropriate information as voice information. Output to the speaker 31.
The work storage unit 30 stores destination information and route information processed by the controller 10.
The above configuration is the same as that of a conventional navigation apparatus.

Next, the camera 24 mainly images the head of the driver, and in particular outputs an image signal of the eyes such as the face and pupil to the controller 10.
The controller 10 further performs behavior of detecting the behavior of the driver and the three-dimensional gaze direction by performing image processing on the image signal from the camera 24 in order to provide information on a genre that the driver is interested in while driving.・ Gaze direction detection unit 15, focused building identification unit 16 that identifies a building existing in the viewing direction as a focused building visually recognized by the driver, and genre determination that determines a genre that the driver is interested in from the identified focused building A unit 17 and an interest information search unit 18 that searches for building information of a genre that the driver is interested in from map data information, and outputs and displays the information on the display 40.

In the behavior / gaze direction detection unit 15, in order to reduce the load of image processing, a range narrowed around the driver's head in the image is set as an image processing region. For this reason, since the seat position of the driver's seat is detected based on the seat position signal from the seat position sensor 25 and thereby the driver's physique can be statistically grasped, the head of the driver seated in the driver's seat Detect position.
Regarding the detection of the line-of-sight direction, a number of methods are already known and can be arbitrarily selected, such as a method using a cornea reflection image, a method using Purkinje image detection, and the like.

  As for the behavior, the movement of the eyeball, the change in the position of the head, and the like are detected by image recognition. In particular, the change in the position of the head can be extracted from the change in the direction of the nose. If the eyeball moves more than the head position change, it is determined that the behavior is larger, and if both the eyeball movement and the head position change exist, it is determined that the behavior is larger.

The behavior / gaze direction detection unit 15 moves when the gaze direction from the lane of the road at the current position detected by the current position detection unit 11 moves outward (outside the road) beyond the side edge of the road. That is, when it goes to the hatched range R1 or R2 shown in FIG. 4, the detected line-of-sight direction is output to the noted building specifying unit 16.
In FIG. 4, S indicates the lane at the current position.

The position of the side edge of the road as viewed from the driver is the map data information in the map information storage unit 29 including the current position of the vehicle identified within the road width such as the lane, the road width, the distance from each lane to the sidewalk, etc. Can be calculated based on
The reason for limiting the line of sight when the line of sight moves outward beyond the side edge of the road is to avoid confusion between the vehicle on the road and the facilities in the road and the building, and to reduce the processing load.

The noted building identification unit 16 reads the map data information from the map information storage unit 29 to grasp the buildings around the current position, and as shown in FIG. 5, the driver at the current position input from the behavior / gaze direction detection unit 15 The building T1 that intersects the line-of-sight direction M is extracted.
The distance from the current position of the vehicle V to the building is also obtained from the map data.

Here, when there are a plurality of buildings that intersect the line-of-sight direction, such as T1 and T2, the building T1 closest to the current position of the vehicle, that is, the closest to the road is extracted as the building of interest.
On the other hand, for example, when there are two buildings that intersect the line-of-sight direction on a plane, as shown in FIG. 6, the line-of-sight direction M is upward when viewed from the horizontal direction, and the high building T4 behind the low building T3. When the vehicle intersects with the vehicle V, not the lowest building closest to the current position of the vehicle V but the taller building T4 at the rear is the building of interest that the driver has actually visually recognized.

The noted building specifying unit 16 stores the noted building specified as described above in the work storage unit 30.
At this time, as shown in FIG. 7, as the visual record, the building genre of the building, the time when the building was visually recognized, the behavior of the driver (the part moved for the visual behavior), the visual recognition time, and the traveling direction of the vehicle The viewing angle taken by the viewing direction and the viewing distance to the building are simultaneously stored as accompanying information.
Here, department stores, Chinese restaurants, ramen shops, family restaurants, and the like are listed here, but various types of buildings that the driver may be interested in are classified and set in advance. Hereinafter, the building genre is also simply referred to as a genre.

The genre determination unit 17 determines the building genre that the driver is interested in from the visual record stored in the work storage unit 30.
Here, first, in order to avoid misjudgment, the content of the visual record is weighted,
The recorded content is multiplied by each weighting value, and the total value is calculated as the probability.
That is, since there is a high correlation between the interest of a person and the magnitude of the behavior, the greater the behavior, the higher the interest.
In addition, it is estimated that the longer the viewing time, the stronger the interest, and the viewing angle, which is the amount of gaze displacement from the front of the road during normal driving, is also related to the magnitude of interest.

FIG. 8 shows an example in which the driver's behavior, viewing time, viewing angle, and viewing distance are weighted by 7, 10, 6 and 5, respectively, and the probability values calculated based on this are shown.
And a thing with a large probability value is extracted as a building genre that the driver is interested in a predetermined number in the order of the magnitude. Here, for example, Chinese restaurants, ramen restaurants, and family restaurants related to meals have particularly high certainty values, so these three genres can be extracted.

The interest information search unit 18 searches the building genre determined by the genre determination unit 17 from the map data information around the current position of the vehicle, extracts buildings of the same genre, and displays them on the display 40. At this time, a building of the same genre can also be searched from the information distribution center 34 via the communication unit 32.
The display 40 on which the building is displayed by the interest information search unit 18 becomes a destination selection screen, and a signal from the touch switch 41 of the touch panel set on the display 40 is input to the destination setting unit 12. Yes.

FIG. 9 and FIG. 10 are flowcharts showing the flow of control in the controller 10 configured as described above for providing information on the genre that the driver is interested in while driving.
When the power is turned on and the navigation device is turned on (ON), control of the controller 10 is started.
First, in step 100, the image signal from the camera 24 is taken in, and the behavior / gaze direction detection unit 15 detects the behavior and the gaze direction of the driver. As described above, the behavior / gaze direction detection unit 15 outputs the gaze direction toward the outside of the road to the target building identification unit 16.

In step 101, the building-of-interest specifying unit 16 extracts a building in the line-of-sight direction on the map data as the building of interest.
The building of interest is stored in the work storage unit 30 as data of its genre, extracted time, driver behavior, viewing time, viewing angle, and viewing distance.
In step 102, it is checked whether or not the data of the same genre has reached a predetermined number (for example, 5) in any of the buildings of interest stored in the work storage unit 30.
If the data of the same genre has not reached the predetermined number, the process proceeds to step 103. If the predetermined number has been reached, the process proceeds to step 104.

In step 103, it is checked whether or not the presentation timing described later is reached. If the presentation timing is not reached, the process returns to step 100. As a result, the data of the building of interest is updated and accumulated in the work storage unit 30.
When the presentation timing is reached, the process proceeds from step 103 to step 104.

In step 104, the genre determination unit 17 determines and extracts the building genre in which the driver is interested from the data of the building of interest accumulated in the work storage unit 30.
In the example of FIG. 8, the genre that the driver is interested in is determined in the order of the ramen restaurant, the Chinese restaurant, and the family restaurant, from the group with the highest probability value, and is rearranged as shown in FIG. 11. For simplicity, FIGS. 8 and 11 show a state in which a building of interest of each genre occurs once. The comparison of the probability values is actually carried out by counting for each genre.

In the next step 105, it is checked whether the destination has already been set by operating the input unit 26 or the like.
If the destination has not been set yet, the routine proceeds to step 106, and if the destination has already been set, the routine proceeds to step 107.
In step 106, the interest information search unit 18 searches for the building of the genre determined by the genre determination unit 17 from the map data information around the current position of the vehicle.
On the other hand, in step 107, the search is performed by narrowing down the buildings existing on the left side of the road so that a U-turn or a right turn is not required on the route to the destination.

  After searching for a building in Steps 106 and 107, in Step 108, the interest information search unit 18 determines a genre building (a ramen shop in the example of FIG. 11) having the highest probability value as a destination candidate, The destination candidates are displayed on the display 40 in step 109, and the display is used as a destination selection screen. At the same time, the speaker 31 can also provide guidance by voice such as “There is Δ △ ahead of ○○ km. Do you want to select the destination?”.

The display 40 has a touch panel as its surface, and on the destination selection screen, as illustrated in FIG. 12, a plurality of destination candidates P1, P2,. Note that the part where the destination candidates P1, P2,... Are displayed on the screen corresponds to the touch switch 41 in FIG.
In addition, a “next” button B1 for displaying the next candidate and an “end” button B2 for simply ending the display without setting the destination are displayed on the display screen.

In step 110, it is checked whether a destination candidate has been selected.
If any destination candidate is touched and selected on the destination selection screen, the process proceeds to step 111, and the candidate is set as the destination in the destination setting unit 12.
As a result, when the vehicle is traveling with no destination set, the optimum route to the building determined as the destination by the route search unit 13 is the same as when the destination is set by the operation from the input unit 26. And the route is finally displayed on the display 40.
If the destination has already been set, the optimum route as a transit point or a new destination (for example, farther than the set destination) is determined as the destination set by the route search unit 13. Is searched, and a new route is displayed on the display 40.

When the genre of the destination candidate displayed in step 109 is different from the genre desired by the driver, when the “next” button B1 is touched, the process proceeds from step 110 to step 112, and the extracted genre is certain. It is checked whether a building of the genre having the next largest value remains, and if it remains, for example, a Chinese restaurant is set as a new destination candidate in step 113. Then, returning to step 109, the display 40 is set as the destination selection screen.
If there is no remaining genre building with the next highest probability value, the process proceeds to step 114, and after displaying for a predetermined time that there is no other destination candidate, the process proceeds to step 115.

On the other hand, if the “end” button B2 on the destination selection screen is touched, the process proceeds from step 110 to step 115.
In step 115, the destination selection screen is deleted, and the normal navigation screen for displaying the map around the current current location or displaying the route to the already set destination is displayed.
After step 111 or step 115, the data of the building of interest stored in the work storage unit 30 in step 116 is deleted, and the current flow is terminated.
Finally, the data of the building of interest is erased from the working memory to avoid the same information being repeatedly displayed on the destination selection screen even after selecting the destination or making the destination setting unnecessary. is there.
This flow is repeatedly executed in parallel with other processes while the navigation device is on.

The presentation timing for displaying the destination candidate (building) to be checked in step 103 described above on the display 40 is, for example, immediately before the vehicle enters a traffic jam.
The location of the traffic jam can be grasped from the current traffic jam information acquired as VICS information or the like by the traffic information acquisition unit 23 or the statistical traffic information included in the map data information of the map information storage unit 29.
At such time, providing the building information of the genre that the driver is interested in can help to shift the time to depart to the building and enter the traffic jam.

Further, when the behavior of the vehicle changes significantly, for example, when the inter-vehicle distance detected by the radar 27 is shortened and the speed of the vehicle detected by the speed sensor 21 is reduced, it can be determined that a traffic jam has actually occurred.
Even in this case, if there is a building of the genre that the driver is interested in in the traffic jam section, by providing that information, it is possible to effectively use the time during the traffic jam such as taking a rest in the building or buying drinks in the building. it can.

In addition to the above, the presentation timing may be when the passenger is determined to be bored, when there is a high probability that information will be required, such as during mealtimes, or when the weather is likely to change. It is set in advance.
The occupant's boredom can be determined from the state in which the television / audio detected by the in-vehicle device operation detection unit 28 is frequently operated, and is a suitable timing for providing new information.
Information such as a restaurant where you can eat is required during a time when everyone feels hungry, and the time can be detected by the built-in clock of the controller 10.
When the weather changes, a situation in which some facility is desired to be used is likely to occur according to the change, and can be determined from a wiper, an air conditioner, or a light switch operation detected by the in-vehicle device operation detection unit 28.
Therefore, when one of the plurality of presentation timings described above is reached, the process proceeds from step 103 to step 104.

In the present embodiment, the building corresponds to an external object in the invention, and the building of interest corresponds to the object of attention.
Further, the behavior / gaze direction detection unit corresponds to the image processing unit of the invention, the attention building specifying unit corresponds to the attention target specifying unit, and the genre determination unit corresponds to the genre determination unit.
Then, interest information to be displayed on the display 40 or the speaker 31 by searching for the building similar to the genre determined by the genre determining unit 17 from the map data information in the map information storage unit 29, the map data in the information distribution center 34, and the facility information. The search unit constitutes interest information presentation means.

  The embodiment is configured as described above. The camera 24 images the driver's head, the behavior / gaze direction detection unit 15 that detects the gaze direction of the driver from the image signal of the camera, and the building in the gaze direction. The building-of-interest specifying unit 16 that identifies the building as the building of interest, the genre determining unit 17 that determines the genre that the driver is interested in from the building of interest in this trip, and the genre information determined by the genre determining unit on the display 40 Since the interest information search unit 18 to be presented to the speaker 31 is included, information of interest at the present time is selected and provided at a good timing.

  At this time, the building of interest specifying unit 16 specifies the building of interest only with respect to the line-of-sight direction from the current position of the vehicle toward the outside of the road, so that the processing load is reduced.

Further, since the genre determination unit 17 determines the building genre as the driver's interest is higher as the driver's behavior detected by the behavior / gaze direction detection unit 15 is larger, the genre determination accuracy is higher.
Furthermore, since the genre determination unit 17 determines that the driver's interest in the building is higher as the visible time of the building is longer, high determination accuracy can be obtained also by this.

Further, the genre determination unit 17 extracts a plurality of genres with high certainty, and the interest information search unit 18 presents buildings of each genre in the order of genres with high certainty. Surely provided.
Then, the interest information search unit 18 automatically displays a building with high interest of the driver on the display 40 as a destination candidate, and the destination can be selected on the display. Therefore, a complicated procedure from the input unit 26 is performed. It is not necessary to perform the preparation operation, and it can be easily set as a destination or a waypoint.

Buildings of a genre that are highly interested by the driver are displayed when the number of buildings of interest that the driver has visually recognized reaches a predetermined number, so that the information required by the driver is provided particularly quickly.
In addition, when the vehicle behavior changes significantly, just before the vehicle enters a traffic jam, when it is determined that the occupant is bored for a predetermined time, or when the weather changes, etc. Since the building is presented, convenience is enhanced in accordance with each state.

In the above embodiment, the camera 24 is dedicated for imaging the driver's head. For example, when a lane departure prevention system is installed, the camera 24 is used for imaging the road ahead of the vehicle. By adding a prism or the like to the camera so that the direction of the driver's seat can be imaged, it is possible to simplify the configuration and to reduce the cost by using both.
At this time, even if the imaging range (imaging angle) of the camera of the lane departure prevention system is large, the head position can be detected from the seat position by the seat position sensor 25 to narrow down the image processing area.

Also, in the embodiment, in order to limit the line-of-sight direction to the outside of the road, it is determined from the map data information which lane on the road the vehicle's current position is. In this case, it may be detected on which lane the vehicle is located from the image captured by the camera.
As a further simplified method for limiting the line-of-sight direction to the direction toward the outside of the road, the driver can visually recognize the corner of the front end of the vehicle body in a stopped vehicle, and the line-of-sight direction detected at this time is built into the controller 10. There is pre-learning stored in the memory or the work storage unit 30, and a direction facing outward from the stored line-of-sight direction can be set as a line-of-sight direction facing out of the road.

Although the probability of building genre is expressed by numerical values, weights are given to the driver's behavior, viewing time, visual angle, and visual distance, but the numerical values of the weights are examples, and the values differ depending on the driver. Alternatively, it may be set or changed by the driver himself.
Also, when the same behavior is shown with respect to the same genre, it is clearly shown that the user is interested, so that it can be used as accompanying data.

As for the viewing distance, weighting is performed on the assumption that the greater the distance, the greater the interest. It is appropriate to perform weighting.
Also, highly accurate weighting can be obtained by comparing the contents of the visual record with the point (= destination) where the driver actually parked the vehicle.

Further, in the embodiment, an example has been shown in which a building of a genre that the driver is interested in is presented as a destination candidate, but it may be simply displayed on the map as peripheral information.
On the other hand, when the presented destination candidate is set as the destination, it may be set by a driver's utterance using voice recognition in addition to a manual operation such as touching a touch switch.

  In addition, the presentation timing of buildings of the same genre is assumed to be preset, but in addition to this, the driver may arbitrarily set the timing, and further, for example, by touching a touch button or the like when viewing Of course, it may be displayed immediately.

In the embodiment, the direction in which the driver's line of sight is detected and the driver is interested in the target building, but the information on which the passenger is interested based on the line of sight of the passenger in the passenger seat or the rear seat is displayed. You may make it show.
Furthermore, the external object that the driver and the occupant are interested in is not limited to a building, and can be an event or the like as long as it can be classified as a specific genre.
