Description

  The present invention relates to a safety confirmation advice device that is mounted on an automobile or an automobile driving simulation device and that advises the driver's gaze allocation.

  As a technology for judging the safety of the driver and presenting the judgment result, the driver's gaze is measured to determine the coordinates of what he is looking at, and the gaze target to be seen in advance (mirror, instrument, front 2. Description of the Related Art A vehicle driver training system (see, for example, Patent Document 1) is known that determines whether or not safety confirmation is good or not by comparing the coordinates of a glass or the like with the frequency of viewing a target.

  Also, based on the intersection's geometric shape, own vehicle position information, and line-of-sight measurement information, the right / left confirmation is judged based on whether or not the intersection road is seen before the intersection. There is known a vehicle information notification device (for example, see Patent Document 2) that notifies support information.

Furthermore, if the driver's face direction is measured and a driving environment that requires safety confirmation (lane change or turn left or right by blinking direction indicator, car navigation device pause information or railroad crossing information) is recognized, the face moves left and right. There is known a safety promoting device for automobiles (for example, refer to Patent Document 3) that determines whether or not safety confirmation is performed based on whether or not the vehicle has been confirmed and issues an alarm when the confirmation is not performed.

  However, since the vehicle driver training system of Patent Document 1 targets a predetermined gaze target, it can be implemented only in a regular learning course, a simulator, or the like. In addition, since the gaze target is a mirror, instrument, windshield, etc., the relevance to the traffic environment and traffic conditions is not clear, the problem is that the validity of the safety check results and the driver's satisfaction are low. There is.

  Since the vehicle information notification device of Patent Document 2 only determines the line of sight and the face direction according to the geometric shape of the intersection (intersection angle of the intersection road), it can only determine whether the right and left confirmation is regular. In addition, since “whether or not it is seen” is determined by “whether or not the face direction exceeds a certain angle”, there is a problem that it is determined as “good (sufficient confirmation)” if the face is turned even once. .

  In the safety promoting device for automobiles of Patent Document 3, the face direction is measured depending on whether the driver's face has moved left and right (whether the deviation from the feature amount of the face image facing the front is large). There is a high possibility that the state of is erroneously recognized as “checking left and right”. In addition, there is a problem that only good or bad of regular confirmation such as mirror confirmation and left and right confirmation can be determined.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, this invention is not limited to the following embodiment, It is applicable also to what changed the design within the range described in the claim.

<First Embodiment>
FIG. 1 is a block diagram showing the main configuration of the safety confirmation advice device according to the first embodiment. The safety confirmation advice device includes a travel position specifying unit 11, a gaze measurement unit 12, a map DB 13, a gaze distribution calculation unit 14, an ideal gaze distribution derivation unit 15, a gaze distribution determination unit 16, and an advice presentation unit 17. And.

  The traveling position specifying unit 11 specifies the current position of the host vehicle. When the safety confirmation advice device is mounted on an automobile, the traveling position specifying unit 11 corresponds to a GPS sensor, and thereby detects the own vehicle position. When the safety confirmation advice device is installed in an automobile driving simulation device (driving simulator), the traveling position specifying unit 11 corresponds to a circuit that is provided in the device and specifies a specific position as the own vehicle position.

  The line-of-sight measurement unit 12 measures the driver's line of sight. In this embodiment, a so-called camera type eye tracker is used. A camera for capturing a face image is installed or built in above the windshield, on the dashboard, on the steering column, in the rearview mirror, or the like. The line-of-sight measurement unit 12 captures the driver's face image with one or more cameras, detects facial feature parts such as eyes and nose by image processing, and measures the line-of-sight direction from the positional information and the position of the feature part. To do.

  The map DB 13 is a map provided in the car navigation device, and electronically holds map information including road shapes (for example, linearity, curvature, intersection, etc.). FIG. 2 shows a format example of map information held in the map DB 13. As shown in FIG. 2, for example, an intersection map is based on information such as lanes and sidewalks if the map information to be held is a detailed city map or the like. Divided into multiple areas based on the angle. FIG. 2 shows an example of an area in the case of a signalized intersection, and the periphery of the intersection is divided into areas (1) to (15) (illustrated by circled numbers in the drawing, the same applies hereinafter). As for the area information, detailed area information defined in advance may be stored together with the map, or an intersection in the traveling direction may be roughly calculated by calculation according to the vehicle position.

  The line-of-sight distribution calculation unit 14 develops the driver's line of sight measured by the line-of-sight measurement unit 12 on the map of the map DB 13 corresponding to the traveling position of the host vehicle identified by the traveling position identifying unit 11, and Calculates how much the area on the road corresponding to which area on the map is actually viewed, and the line-of-sight distribution for each area.

  The line-of-sight distribution calculation unit 14 determines the confirmation area for each 0.1 second frame within the time from approach to approach to entry to the right turn at the time of turning right at the intersection. The confirmation ratio is calculated, and this confirmation ratio is set as the line-of-sight distribution of each area.

  For the confirmation area, the line-of-sight distribution calculation unit 14 acquires line-of-sight vector information from the line-of-sight measurement unit 12, and determines an area that intersects the line-of-sight vector from the vehicle position as the confirmation area. For example, the inner product of the line-of-sight vector and the vector from the vehicle position to the center coordinates of each area (areas (1) to (15) in FIG. 2) is calculated, and the area having the maximum value is set as the confirmation area. The confirmation ratio of each area is calculated by equation (1).

Area X confirmation ratio = Number of frames for which area X has been confirmed / total number of frames (1)
FIG. 3 shows an image of the confirmation ratio of each area calculated in this way. In the figure, each area is painted according to the height of the confirmation ratio. However, it is not necessary to actually hold the image information as shown in FIG.

  The ideal line-of-sight distribution deriving unit 15 calculates an ideal line-of-sight distribution as to how much the area on the road corresponding to which area on the map of the map DB 13 should be viewed at the travel position specified by the travel position specifying unit 11. To derive. In the present embodiment, an ideal line-of-sight distribution is obtained by calculation as follows.

  For example, when turning right at the intersection shown in FIG. 2, the importance of each area is determined according to the following rules. It is assumed that the vehicle turns right by the route setting of the car navigation device or the signal from the direction indicator.

・ Increase the importance of area (1) (2) (3) (4) (13) (14)
・ Increase the importance of areas (3), (4), (6), (12), (13), and (15) with traffic that crosses the path of your vehicle by 1
・ Increase the importance of areas (3), (12), (13), and (15) that may be pedestrians
・ If there are multiple oncoming lanes (if information is available), increase the importance of area (6) by 1
According to this rule, the cumulative importance of each area is obtained as follows.

(1) = 1, (2) = 1, (3) = 3, ... (14) = 1, (15) = 2
Based on this cumulative importance, the importance ratio of each area is calculated by equation (2).

Area X importance ratio = Area X importance / total importance of all areas (2)
The importance ratio calculated in this way is used as a criterion for determining safety confirmation as an ideal line-of-sight distribution in each area. FIG. 4 shows an image of the importance ratio of each area. In the figure, each area is painted according to the importance ratio. However, it is not necessary to actually hold the image information as shown in FIG.

  Further, the importance ratio is not a fixed value for each area around a specific intersection. As the vehicle moves, the value changes depending on the relationship with the traveling position of the vehicle. FIG. 5 is a diagram illustrating that the importance ratio (ideal line-of-sight distribution) of each area differs depending on the vehicle position. FIG. 5 shows the importance ratio of each area, divided into four stages from when the vehicle 50 approaches the intersection and turns right at the time of turning right at the intersection.

  In FIG. 5A, the own vehicle 50 is located near the intersection, and the importance ratio is high in the oncoming lane (6). FIG. 5B is when the own vehicle 50 enters the intersection, and the importance ratio is high for (7) traffic lights. In FIG. 6C, the own vehicle 50 is located near the center of the intersection, and the importance ratio is high in (5) the pedestrian crossing at the back of the intersection, (6) the opposite lane, and (15) the sidewalk at the right back. In FIG. 4D, the own vehicle 50 is turning right at the intersection, and the importance ratio is high in (15) the right sidewalk and (14) the right side roadway.

  In this way, since the importance ratios of the surrounding areas that change for each vehicle position are obtained, it is possible to know which area the driver should see as the vehicle moves. FIG. 6 is a table showing that the importance of each area varies depending on the vehicle position.

  The line-of-sight distribution determination unit 16 is calculated by the actual driver's line-of-sight distribution and the ideal line-of-sight distribution at the driving position, that is, the above-described confirmation ratio calculated by the line-of-sight distribution calculation unit 14 and the ideal line-of-sight distribution deriving unit 15. A comparison result with the above-described importance ratio is determined.

  The line-of-sight distribution determination unit 16 determines the line-of-sight distribution as follows. First, the difference or ratio between the confirmation ratio and the importance ratio is calculated for each area. For example, when calculating the difference, “importance ratio−confirmation ratio” is obtained, and an area having the largest difference is set as “attention required area”. That is, when the importance ratio is larger, this area is insufficiently confirmed, and when the confirmation ratio is larger, attention is required in the sense that this area is viewed more than necessary. Furthermore, the sum of the differences (only positive values) for each area is used as a standard for evaluation of safety confirmation with the total score.

  The advice presenting unit 17 presents advice on excess or deficiency of the safety confirmation to the driver based on the determination result of the line-of-sight distribution determining unit 16. FIG. 7 shows an example of advice presentation. In the present embodiment, the advice is displayed on the screen 70 of the car navigation device. In FIG. 7, a graph 71 and a one-point advice 72 are displayed.

  The graph 71 shows the quality of the safety confirmation by displaying the above-mentioned total score in a graph. That is, the quality of safety confirmation is based on the overall score. In the graph 71, the total score up to the present is displayed in time series, and this is updated every time a point of interest such as an intersection is reached.

  The one-point advice 72 prompts the driver by displaying the points to be noted at the intersection in the traveling direction, that is, the area 73 and the message 74 having the highest importance ratio described above before passing the intersection. In the example of FIG. 7, advice is displayed in advance, but a message may be displayed after passing the intersection. For example, if the confirmation ratio of an area with a high importance ratio when passing through an intersection is too low, or the confirmation ratio of an area with a low importance ratio is too high, an excess or deficiency of safety confirmation may be fed back.

  Also, a voice advice ON / OFF button 75 is provided, and at the next XX intersection, check the sidewalk in front of your right. If combined, the driver's attention can be alerted more reliably.

  As described above, the safety confirmation advice device according to the first exemplary embodiment calculates the driver's line-of-sight distribution and ideal line-of-sight distribution for each traveling position, and provides the driver with the result of comparison between the two. Effective advice on safety confirmation behavior can be presented.

Unlike the first embodiment, an ideal line-of-sight distribution DB 18 is further provided, and the ideal line-of-sight distribution deriving unit 15 derives an ideal line-of-sight distribution based on the ideal line-of-sight distribution DB 18.

  The ideal line-of-sight distribution DB 18 holds an ideal line-of-sight distribution calculated in advance for each predetermined travel position.

  For example, if the traveling course is a course prescribed as a driving simulator course or driving school training course and it is known to turn right, the ideal line-of-sight distribution when turning right at a signalized intersection is obtained in advance. Keep it.

  As a method of obtaining an ideal line-of-sight distribution, the importance ratio of each area that has been calculated in advance by the method of the first embodiment may be used, or a safe driver (such as a school instructor) may follow the same route in advance. The confirmation ratio at the time of traveling may be used. FIG. 9 shows an image of the importance ratio of each area obtained in this way.

  The ideal line-of-sight distribution deriving unit 15 reads out the ideal line-of-sight distribution at the travel position from the ideal line-of-sight distribution DB based on the travel position specified by the travel position specifying unit 11.

  As described above, the safety confirmation advice device according to the second embodiment obtains and holds the ideal line-of-sight distribution for each travel position in advance and reads it when traveling at each travel position. As a result, the calculation cost of the computer is reduced, so that even a computer with a lower processing capability can be implemented.

The traffic condition acquisition unit 19 may acquire such information using a sensor (optical type, radio wave type, etc.) mounted on the vehicle, road-to-vehicle communication, vehicle-to-vehicle communication, communication with a data center, etc. May be obtained by

  The ideal line-of-sight distribution deriving unit 15 considers not only the map information stored in the map DB 13 as in the first embodiment, but also the importance of each area in consideration of the traffic situation acquired by the traffic situation acquisition unit 19. Calculate the ratio.

  The ideal line-of-sight distribution deriving unit 15 calculates the importance of each area when turning right at the signalized intersection shown in FIG. 11 based on the following rules. Making a right turn is known in the route setting of the car navigation device.

  First, as in the first embodiment, the importance of each area (1) to (15) is determined based on the map information.

・ Increase the importance of area (1) (2) (3) (4) (13) (14)
・ Increase the importance of areas (3), (4), (6), (12), (13), and (15) with traffic that crosses the path of your vehicle by 1
・ Increase the importance of areas (3), (12), (13), and (15) that may be pedestrians
・ If there are multiple oncoming lanes (if information is available), increase the importance of area (6) by 1
In addition to this, the importance of each area is determined based on the traffic situation acquired by the traffic situation acquisition unit 19.

・ If the color of the signal is a right turn arrow, increase the importance of (7) by 1
・ If there is an oncoming vehicle, increase the importance of (6) by 1
・ If there is an intersection from the right, increase the importance of (14) by +1
・ If there is a pedestrian trying to cross, the importance of (12) (15) is +1
Based on the importance determined in this way, the importance ratio of each area is calculated by the above equation (2). FIG. 11 shows an image of the importance ratio of each area obtained in this way.
