  The recording unit 12 includes a road information database (hereinafter referred to as “DB”) 12a and an out-of-view area DB 12b. The road information DB 12a is road information storage means for storing road information. Road information is a road that identifies features such as the position, number of lanes, and the shape, color, and brightness of lane markings (solid lines, broken lines, double lines, etc.) that are painted on the road to distinguish the lanes. It includes information on feature information, the presence / absence of a three-dimensional structure on the road that divides the traveling form of the road, and the position of the discontinuous portion of the three-dimensional structure. The road information DB 12a can be shared with a road information DB storing map display data, intersection data regarding intersections, and the like in a known navigation device.

  The out-of-view area DB 12b stores speed information for specifying the speed of the host vehicle and out-of-view area information for specifying an out-of-view area in the driver's basic view area in association with each other. Here, the “basic visual field area” refers to an area set in advance as an area to be displayed on the display 50 in the image information in front of the vehicle imaged by the camera 20. In addition, the “out-of-view area” refers to an area that is difficult to view due to the fact that the viewpoint position of the driver moves away according to the speed of the vehicle. A region that is difficult to visually recognize in the basic visual field region is stored as out-of-field region information. In addition, the “safe area” is an area where there is no other moving body that may enter the lane in which the host vehicle is traveling, such as a median strip or a protective wall provided on the road. It means an area where there is an oncoming lane or a sidewalk separated by a three-dimensional structure such as.

  As specific contents of the out-of-view area information, for example, a portion corresponding to the out-of-view area of the driver in the image information of the basic view area included in the image information in front of the vehicle taken by the camera 20 It can comprise as information specified using the pixel position of information. FIG. 2 is a diagram showing image information of a basic visual field area where the number of pixels in the horizontal direction in the image information photographed by the camera 20 is 800 and the number of pixels in the vertical direction in the image information is 400, and FIG. It is the table | surface which illustrated the content. As shown in FIG. 3, the information corresponding to the item “speed” and the item “out-of-view area” is stored in the out-of-view area DB 12b in association with each other. The information stored in correspondence with the item “speed” is speed information, for example, information indicating the speed such as “20 km / h” is stored. The information stored corresponding to the item “out-of-view area” is out-of-view area information. For example, the pixel position range for specifying the area corresponding to the out-of-view area in the image information of the basic view area is stored. Has been.

  For example, FIG. 2 shows an out-of-view area that exists at both ends of the image information of the basic view area when the vehicle speed is 20 km / h. The numbers in the figure are coordinate values indicating pixel positions when the lower left corner of the image information is the origin. In this case, as shown in FIG. 3, the out-of-view area information corresponding to the speed information “20 km / h” in the out-of-view area DB 12b includes “0-40” as the horizontal pixel position range at the left end, “0 to 400” as the vertical pixel position range at the end, “760 to 800” as the horizontal pixel position range at the right end, and “0 to 400” as the vertical pixel position range at the right end. Stored. In the example shown in FIG. 2, the shape of the out-of-view area information in the basic view area is approximated as a rectangle, but the out-of-view area information can also be configured by approximating an elliptical shape or a circular shape.

(Configuration-Camera)
The camera 20 is a photographing means for photographing a region including the driver's basic visual field region, and is disposed, for example, at the front end of the vehicle. Specifically, for example, an area that the driver can visually recognize through the front window 2 of the vehicle can be set in advance as an area to be displayed on the display 50 (that is, a basic visual field area). An area including an area that can be visually recognized through the front window 2 is defined as an imaging area. The captured image information is output from the camera 20 to the control unit 11. The camera 20 is configured using a known imaging device such as a CCD sensor or a CMOS sensor, and a known optical system component.

(Configuration-vehicle speed sensor)
The vehicle speed sensor 30 detects the speed of the vehicle and outputs the detected value to the control unit 11, and a known vehicle speed sensor can be used.

(Configuration-Current location detection processing unit)
The current position detection processing unit 40 is a current position detection unit that detects a current position of a vehicle (hereinafter referred to as “own vehicle” if necessary) to which the driving support device 10 is attached. Specifically, the current location detection processing unit 40 has at least one of a GPS, a geomagnetic sensor, a distance sensor, and a gyro sensor (all of which are not shown) and knows the current position and direction of the own vehicle. To detect.

(Configuration-Display)
The display 50 is output-controlled by the notification control unit 11c and displays the driving support information so as to notify the driving support information. The display 50 is always included in the driver's view regardless of the speed of the host vehicle. It is arranged in front of the driver. FIG. 4 is a diagram showing the display 50 installed in front of the driver. As the display 50, a known flat panel display such as a liquid crystal display or an organic EL display can be used.

(processing)
Next, driving support processing executed by the driving support system 1 configured as described above will be described below. FIG. 5 is a flowchart showing a driving support process executed by the driving support system 1 (steps are abbreviated as “S” in the description of each process below).

  The timing for starting the driving support process is arbitrary. For example, the process can be started when the engine is started or when the shift position is set to the drive range. When the driving support process is started in this manner, the notification control unit 11c starts shooting the landscape in front of the driver with the camera 20 (SA1), and the basic visual field region of the image information shot with the camera 20 Is displayed on the display 50 as driving support information (SA2).

  Next, the out-of-view area specifying unit 11a acquires the vehicle speed based on the detection value input from the vehicle speed sensor 30 (SA3), refers to the out-of-view area DB 12b based on the acquired vehicle speed, An area outside the visual field of the driver at the speed is specified (SA4).

  Subsequently, the attention target region setting unit 11b causes the current position detection processing unit 40 to detect the current position of the host vehicle, refers to the road information DB 12a based on the detected current position, and determines the three-dimensional of the road on which the host vehicle is traveling. The presence / absence of a median strip as a structure is specified (SA5). As a result, if it is determined that a median strip is provided (SA6, Yes), is the road information DB 12a referred to based on the current position, and whether there is a disruption in the median strip within a predetermined range in front of the host vehicle? It is determined whether or not (SA7). As a result, when it is determined that there is no disruption in the median strip within the predetermined range ahead of the host vehicle (SA7, Yes), the rightmost lane that is closest to the median strip on the road on which the vehicle is traveling is It is determined whether the vehicle is traveling in a lane (SA8).

  Specifically, the caution target area setting unit 11b is a lane line for dividing a plurality of lanes in the same direction among road feature information stored in the road information DB 12a from the image information captured by the camera 20. Image candidates having high consistency with the paint display feature data are extracted, and recognized as a lane marking paint display image. If the recognized lane marking does not exist on the right side of the host vehicle, it is determined that the host vehicle is traveling in the rightmost lane. If the recognized lane marking is on the right side of the host vehicle, the host vehicle Is determined not to travel in the rightmost lane.

  As a result, when it is determined that the host vehicle is traveling in the rightmost lane (SA8, Yes), the attention target area setting unit 11b is provided with a median in a predetermined range in front of the host vehicle on the right side. Therefore, there is a moving body such as other vehicles or pedestrians that may enter the lane in which the host vehicle is traveling in the area opposite to the traveling lane of the host vehicle with respect to the central separation zone. It judges that it does not carry out, and the said area | region on the opposite side to the driving lane of the own vehicle is specified as a safety area (SA9). Subsequently, the attention target area setting unit 11b sets the attention target area according to the out-of-view area specified in SA4 and the safety area specified in SA9 (SA10). That is, according to the safety area, an area that should be noted by the driver in the out-of-view area is set as the attention target area. As the specific configuration described above, for example, among the out-of-view areas specified in SA4, only the out-of-view area that does not include the safety area is set as the attention area, or the out-of-view area corresponds to the safety area. A configuration in which an area from which the area has been deleted is set as the attention area is raised. However, if it is determined in SA6 that no median strip is provided (SA6, No), if it is determined in SA7 that there is a disruption in the median strip (SA7, No), or the vehicle is the most in SA8. When it is determined that the vehicle is not traveling in the right lane (SA8, No), the safety area is not specified.

  Next, the notification control unit 11c highlights a portion corresponding to the attention target region set by the attention target region setting unit 11b in the image of the basic visual field displayed on the display 50 in SA2. Driving support information is reported (SA11). The specific method of highlighting in this case is arbitrary. For example, the portion corresponding to the attention target region in the displayed image is displayed by surrounding it with a frame or increasing the contrast. The portion corresponding to can be highlighted. FIG. 6 is a diagram illustrating a case where a portion corresponding to the attention target region is highlighted in the image displayed on the display 50. As shown in FIG. 6, since the display 50 itself is located within the field of view, it is possible to reliably check the attention target area via the display 50.

(effect)
As described above, according to the first embodiment, the out-of-view area that changes according to the speed of the vehicle is specified, and the driving support information related to the attention target area that is set according to the out-of-view area is displayed on the display 50. Therefore, it is possible to easily alert the driver to a region outside the driver's visual field range.

  Further, driving support information that sets a caution target area in accordance with a driver's out-of-view area in a preset basic visual field area and makes it possible to identify the caution target area and the basic visual field area excluding the caution target area. Is displayed, it is possible for the driver to distinguish and grasp a region outside his / her field of vision and a region within his field of view within the basic field of view.

  Further, since the region corresponding to the attention target region set by the attention target region setting unit 11b is highlighted on the display 50, the driver can select the region outside the field of view in the basic visual field region and the region within the visual field. It becomes possible to distinguish and grasp the area.

  In addition, if there is a safety area adjacent to the driving lane of the vehicle, the attention target area is set according to the out-of-view area and the safety area. It becomes possible to do.

[Embodiment 2]
Next, a second embodiment will be described. In this mode, in addition to the speed of the host vehicle, a driver's visual field that changes according to the driver's line-of-sight movement is specified, and a display that indicates a portion corresponding to the attention target area on the front window is supported for driving. The information is projected directly on the front window as information. The configurations of the second embodiment and the subsequent embodiments are substantially the same as those of the first embodiment unless otherwise specified, and the configurations that are substantially the same as the configurations of the first embodiment are the same as those of the first embodiment. The same code | symbol and / or name as what was used in the form 1 of this are attached | subjected as needed, and the description is abbreviate | omitted.

(Configuration-Projector)
The driving support system 1 according to the second embodiment includes a projection device (not shown). The projection device is output-controlled by the notification control unit 11c, and directly projects onto the front window 2 a display indicating a portion corresponding to a region outside the visual field on the front window 2 as driving support information. As this projection apparatus, a known head-up display projector can be used. Although a specific display mode is arbitrary, for example, a portion corresponding to a region outside the driver's field of view on the front window 2 can be enclosed and displayed or can be lit up.

(Configuration-out-of-view area DB)
In the second embodiment, the out-of-view area information stored in the out-of-view area DB 12b can be configured as coordinate information indicating a range corresponding to the out-of-view area of the driver in the front window 2.

As shown in FIG. 7, corresponding to the item “out-of-view area” in the out-of-view area DB 12 b, information indicating the range of the out-of-view area in the front window 2 by the distance from the left and right ends of the front window 2. As shown in FIG. In the example shown in FIG. 7, the distances from the left and right ends of the front window 2 are shown as a percentage of the total width of the front window 2. For example, when the speed of the host vehicle is 20 km / h, the 5% range from the left and right ends of the front window 2 to the entire width of the front window 2 is the out-of-view area. FIG. 8 is a diagram showing an out-of-view area in the front window 2 when the speed of the host vehicle is 20 km / h. In the example shown in FIGS. 7 and 8, the position of the out-of-view region in the front window 2 is bilaterally symmetric, but can be asymmetrical depending on the seating position of the driver. For example, in a right-hand drive vehicle, the position of the out-of-view area when the speed of the host vehicle is 20 km / h can be set to 15% from the left end of the front window 2 and 5% from the right end.

(processing)
Next, a driving support process executed by the driving support system 1 according to the second embodiment will be described. FIG. 9 is a flowchart showing a driving support process executed by the driving support system 1. Note that the processes from SB1 and SB4 to SB10 are the same as the processes from SA3 and SA5 to SA11 in the driving support process according to the first embodiment, and a description thereof will be omitted.

  After the vehicle speed is acquired in SB1, the out-of-view area specifying unit 11a detects the driver's line-of-sight movement (SB2). The driver's line of sight movement is, for example, directly detected using a known line of sight detection sensor, as well as a configuration for estimating the driver's line of sight movement based on the behavior of the vehicle by the output of a gyro sensor, a steering sensor, etc. A configuration in which the driver's line-of-sight movement is estimated by acquiring the road shape in the traveling direction of the host vehicle based on the road information DB 12a is conceivable.

  Next, the out-of-view area specifying unit 11a specifies the out-of-view area of the driver according to the vehicle speed acquired in SB1 and the driver's line-of-sight movement detected in SB2 (SB3). Specifically, similarly to SA4 in the first embodiment, the out-of-view area DB 12b is first referred to based on the acquired vehicle speed, and the driver's out-of-view area at the speed is specified. Further, the position of the out-of-view area in the front window 2 is shifted according to the driver's line-of-sight movement detected in SB2. FIG. 10 is a diagram showing a region outside the field of view on the front window 2 when the movement of the line of sight at the time of a right turn is detected. For example, in the example shown in FIGS. 7 and 8, the out-of-view area in the front window 2 when the speed of the host vehicle is 20 km / h corresponds to the full width of the front window 2 from the left and right ends of the front window 2. If the line of sight is detected when turning right, the range of 20% from the left end of the front window 2 and 0% from the right end is shown in FIG. Identified as

(effect)
As described above, according to the second embodiment, in addition to the same effects as all or a part of the first embodiment, the display indicating the portion corresponding to the attention target area on the front window 2 is used as the driving assistance information. Since the image is projected directly on the window 2, it is possible to easily grasp the attention target area without removing the line of sight from the front window 2 by the driving driver.

  Further, since the driver's out-of-view area is specified in accordance with the driver's line-of-sight movement in addition to the speed of the host vehicle, the driver's out-of-view area that varies during line-of-sight movement can be quickly and reliably specified. .
