Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
Embodiment 1 FIG.
FIG. 1 is a block diagram showing an example of the configuration of the safe driving support apparatus according to Embodiment 1 of the present invention. FIG. 2 is a schematic diagram showing an example of use in which the safe driving support apparatus according to Embodiment 1 is attached to an attachment member installed in a vehicle such as an automobile. FIG. FIG. 2B is a view of the windshield direction from the vicinity of the center of the rear seat behind the driver seat 21 and the passenger seat 22, and FIG.

  As shown in FIG. 1, the safe driving support device 10 includes a calculation unit 1, a front shooting camera 2, a rear shooting camera 3, a meter panel shooting camera 4, an output control unit 5, and a warning generation unit 6. Installed in and used. Although various installation locations are conceivable, for example, as shown in FIG. 2, the installation location is used by being attached to the tip of an attachment member 20 such as an apparatus attachment arm attached to a column supporting the headrest of the driver's seat 21. At this time, the safe driving support device 10 attached to the attachment member 20 is arranged between the driver seat 21 and the passenger seat 22 in the vicinity of the center of the vehicle.

The front photographing camera 2 is a camera that photographs the front of the vehicle through the windshield of the vehicle, and can photograph a preceding vehicle in front of the vehicle, an oncoming vehicle, a person who crosses the front, a building or an obstacle ahead. It is installed in a position where it can be done.
The rear camera 3 is a camera that captures the rear of the vehicle through the rear glass of the vehicle, and is attached to a position where it can capture a vehicle behind the vehicle, a person behind, a building or an obstacle behind the vehicle. Yes.
The meter panel photographing camera 4 is a camera that photographs the meter panel 30 in the vehicle, and is attached at a position where the meter panel 30 viewed by the driver of the vehicle can be photographed.

  The calculation unit 1 acquires the video shot by the front shooting camera 2 and the rear shooting camera 3 and performs image analysis of the video so that there is no risk of contact or collision with the surrounding vehicle or obstacle of the own vehicle. Determine whether or not. Moreover, the video image | photographed with the meter panel imaging camera 4 is also acquired, and the blinker indicator in the meter panel 30 is read by performing image analysis of the video image.

  When the right direction of the blinker indicator is flashing, it is determined that the turn is right, the lane is changed to the right, or the vehicle ahead is overtaken. By combining this with the analysis result of the video imaged by the front camera 2, it is determined whether the vehicle is turning right, changing the lane to the right, or overtaking the preceding vehicle. That is, if it is determined from the video taken by the front camera 2 that the vehicle is decelerating, turn right, if the vehicle speed remains constant, change the lane to the right, and if the vehicle is accelerating. It can be determined that the vehicle is overtaking from the right side of the preceding vehicle.

  On the other hand, when the left direction of the blinker indicator is blinking, it is determined that the vehicle is either turning left or changing lane to the left. By combining this with the analysis result of the video imaged by the front camera 2, it is determined whether the vehicle is turning left or changing lane in the left direction. That is, it can be determined from the video taken by the front camera 2 that the vehicle turns left if it is determined that the vehicle is decelerating, and it can be determined that the lane changes to the left if the vehicle speed remains constant.

  In addition, if neither the left or right blinker indicator is blinking, it is determined that the vehicle is either going straight or moving backward. This is combined with the analysis result of the video imaged by the front camera 2 to determine whether the vehicle is going straight or backward. That is, it can be determined that the vehicle travels straight if it is determined that the vehicle is moving forward, and it is determined that the vehicle is moving backward if it is determined that the vehicle is moving forward. Alternatively, the transmission range indicator in the meter panel 30 is read from the analysis result of the video photographed by the meter panel photographing camera 4, and if the state represents a forward movement in accordance with the D range or the D range, the vehicle travels straight. If it is P range, it can also be judged as parking.

  FIG. 3 shows the state of the host vehicle as follows: (1) straight ahead, (2) right turn, (3) right lane change, (4) overtaking, (5) left turn, (6) left lane change, (7) It is a flowchart which shows the process which judges whether it is a case of reverse.

  First, based on the video imaged by the meter panel imaging camera 4, it is confirmed whether or not the blinker indicator is blinking (step ST1). If the blinker is blinking (YES in step ST1), it is further determined whether the right direction is blinking or the left direction is blinking (step ST2).

  And when the right direction is blinking (in the case of YES of step ST2), from the analysis result of the image photographed by the front photographing camera 2, whether the host vehicle is decelerating, traveling at a constant speed, or accelerating It is determined whether or not (steps ST3 and ST5). If the host vehicle is decelerating (YES in step ST3), it is determined that the vehicle is turning right (2) (step ST4).

  On the other hand, when the host vehicle is traveling at a constant speed (step ST3 is NO and step ST5 is YES), it is determined that the lane change (3) is in the right direction (step ST6), and the host vehicle accelerates. If it is in the middle (NO in step ST3 and NO in step ST5), it is determined that it is overtaking (4) (step ST7).

  In the determination at step ST2, if the left direction is blinking (in the case of NO at step ST2), whether the vehicle is decelerating from the analysis result of the image captured by the front photographing camera 2 or constant speed is determined. Is determined (step ST8). When the vehicle is decelerating (in the case of YES in step ST8), it is determined that it is a left turn (5) (step ST9), and when the vehicle is at a constant speed (in the case of NO in step ST8), It is determined that the lane change (6) is in the left direction (step ST10).

  On the other hand, if it is determined in step ST1 that the blinker indicator is not blinking (NO in step ST1), whether or not the vehicle is moving forward based on the analysis result of the video shot by the front shooting camera 2. Is determined (step ST11).

  And when moving forward (in the case of YES at step ST11), it is determined that the vehicle is traveling straight (1) (step ST12), and when moving forward (moving backward) ( In the case of NO in step ST11), it is determined that the vehicle is moving backward (7) (step ST13).

  In this way, by determining which of the above-mentioned (1) to (7) is the state of the host vehicle, what should be noted in each case, that is, Targets to be noted can be narrowed down according to the state of the vehicle. Below, the object which should be careful in each case of the state (1)-(7) of the own vehicle is shown.

(1) In the case of straight ahead Pay attention to the distance between the preceding vehicle traveling in front of the host vehicle from the image of the front camera 2 and the distance from the following vehicle of the host vehicle from the image of the rear camera 3. . When there is no preceding vehicle, attention is paid to obstacles on the road ahead, people crossing the road, and the like from the image taken by the front camera 2.

(2) When making a right turn Watch the approaching oncoming vehicle from the image taken by the front camera 2. If you are in the middle of a right turn, be careful of people and bicycles that cross the road you turn right and enter.

(3) When changing the lane in the right direction From the image of the rear camera 3, pay attention to the vehicle approaching from the right rear. From the image taken by the front-facing camera 2, attention should be paid to whether there is a vehicle that is slower than the host vehicle in front of the entering lane and approaches when the lane changes.

(4) In the case of overtaking From the image taken by the front camera 2, there is no oncoming vehicle in front of the lane that is running while overtaking, and if there is an oncoming vehicle, the distance that the overtaking is likely to be completed safely. Watch for speed. Note from the video from the rear camera 3 whether the following vehicle is overtaking the vehicle from the right rear.

(5) In the case of a left turn From the image taken by the front camera 2, if you are in the middle of a left turn, pay attention to people and bicycles that cross the road that you turn left and enter. From the image of the rear camera 3, pay attention to whether a vehicle such as a motorcycle or bicycle is approaching from the left rear and is not caught.

(6) When changing lane in the left direction From the video of the rear camera 3, pay attention to the vehicle approaching from the left rear. From the image taken by the front-facing camera 2, attention should be paid to whether there is a vehicle that is slower than the host vehicle in front of the entering lane and approaches when the lane changes.

(7) Backward Watch out for obstacles and people around the rear from the image taken by the rear camera 3.

As described in (1) to (7) above, by narrowing down the target to be noted according to the state of the host vehicle, it is possible to detect danger more accurately and warn the driver.
In other words, the calculation unit 1 analyzes the image captured by the front camera 2, the image captured by the rear camera 3, and the image captured by the meter panel camera 4, and the vehicle state is determined as described above. (1) to (7), and the object to which the driver of the vehicle is to be noted, and the determined object and the state of the vehicle (any of (1) to (7) above) Or the like), it is determined whether or not there is a risk of contact or collision with the object determined as a vehicle, that is, whether or not there is a positional relationship to be warned.

  In this way, the calculation unit 1 determines whether there is no danger of contact or collision with the surrounding vehicle or obstacle of the own vehicle, that is, whether the own vehicle and the surrounding vehicle or obstacle are in a positional relationship to be warned. If it is determined that the positional relationship is to be warned, the output control unit 5 is instructed to warn the driver of the vehicle.

  When the output control unit 5 determines that the object determined to be a vehicle by the calculation unit 1 is in a positional relationship that should be warned that there is a possibility of contact or collision or that there is a high risk of contact or collision. In order to notify the driver of the vehicle of the danger by sound or display (light of the lamp, etc.) to the warning generation unit 6 in accordance with an instruction (command) to be warned (“warn”) from the calculation unit 1. Let's make a warning.

The warning generation unit 6 receives an instruction from the output control unit 5 and issues a warning for notifying the driver of the vehicle of the danger by voice or display (light of a lamp or the like).
When a warning is given by voice through the speaker 61 of the warning generation unit 6, for example, the volume is increased as the distance from the surrounding vehicle or obstacle is closer. In another example, the sound is a continuous sound of “Peepy Pepper”, and the sound interval is reduced as the distance between the surrounding vehicles and obstacles is closer. Also good.

  Further, when a warning is given by light from the lamp 62 of the warning generation unit 6, for example, the brightness is increased as the distance between the surrounding vehicle and the obstacle becomes shorter. In another example, the color of light may be changed to red, yellow, blue, or the like depending on the distance from surrounding vehicles or obstacles.

  Even when the surroundings are dark, such as at night, the lights from the surrounding vehicles and the reflected light of the light from the own vehicle are photographed by the front photographing camera 2 and the rear photographing camera 3. Even if the surroundings are dark, the above-described operation can be performed without any problem. Further, it is better if the front shooting camera 2, the rear shooting camera 3, and the meter panel shooting camera 4 have a performance capable of obtaining a clear image even in a dark place.

  In the first embodiment, for example, the mounting member 20 such as the arm for mounting the device is attached to the column supporting the headrest of the driver's seat 21 and the safe driving support device 10 is mounted to the tip thereof. If the photographing camera 2 can photograph the front of the vehicle, the rear photographing camera 3 can photograph the rear of the vehicle, and the meter panel 4 can be arranged so as to photograph the meter panel of the vehicle, for example, near the center of the ceiling of the vehicle The mounting location of the mounting member 20 is not limited to the headrest of the seat, such as mounting the mounting member 20 such as an arm from the bottom to the bottom and mounting the safe driving support device 10 at the tip thereof.

  In the first embodiment, the main body of the safe driving support apparatus 10 is a calculation unit 1, a front shooting camera 2, a rear shooting camera 3, a meter panel shooting camera 4, an output control unit 5, and a warning generation unit. 6 is an integrated safety driving support apparatus 10 that is provided in one place. However, the front camera 2, the rear camera 3, and the meter panel camera 4 are connected to the main body of the apparatus using, for example, a USB cable. Thus, the respective cameras may be arranged in the front, rear, and positions where the meter panel 30 can be photographed, and the apparatus main body may be installed on a dashboard or the like.

  In the first embodiment, the safe driving support apparatus 10 also includes the meter panel photographing camera 4. However, if the meter panel 30 can be photographed by attaching a wide-angle lens to the front photographing camera 2, for example, The meter panel photographing camera 4 may not be provided. In this case, the safe driving support device 10 has a simpler configuration and can be provided at a lower price.

  In this case, for example, if a portable information terminal such as a smartphone is equipped with a camera in both the front and the rear, if the wide-angle lens is attached and the meter panel 30 can be photographed as described above, the portable The information terminal may be used as the safe driving support device 10 attached to the attachment member 20. That is, in this case, a portable information terminal such as a smartphone operates alone as the safe driving support device 10.

  Further, in the first embodiment, the safe driving support apparatus 10 includes the calculation unit 1, the front shooting camera 2, the rear shooting camera 3, the meter panel shooting camera 4, the output control unit 5, and the warning generation unit 6. Although described as having a battery (not shown) for supplying power, the battery is unnecessary if the power can be drawn from the vehicle.

  As described above, according to the first embodiment, it is possible to provide a safe driving support device that has a simple configuration, is inexpensive, and can be easily retrofitted.

  As shown in FIG. 4, the safe driving support device 10 </ b> A further includes a GPS (Global Positioning System) receiving unit 7 and / or an acceleration sensor 8, thereby determining the state of the host vehicle with higher accuracy. It becomes possible. That is, it is possible to obtain information directly representing the movement of the host vehicle (forward speed, reverse speed, turning speed, etc.) as compared with the case where the determination is made only by image analysis of the camera video. Further, if the vehicle speed signal is directly taken from the vehicle, the state of the host vehicle can be determined with higher accuracy.

  In addition, as shown in FIG. 4, by adding the microphone 9, it is possible to detect the blinker operating sound (click, click sound) and the transmission R range use sound (beep, beep sound). Compared with the case where the blinker operation and the transmission range are determined only by image analysis, it is possible to determine with higher accuracy.

Embodiment 2. FIG.
