An embodiment of the present invention will be described below based on the drawings.

<Embodiment 1>
<1-1. Configuration>
FIG. 1 is a block diagram showing an example of the configuration of a driving assistance device 1 according to Embodiment 1. As shown in FIG. It should be noted that FIG. 1 shows the minimum required configuration of the driving support system according to the first embodiment.

As shown in FIG. 1 , the driving support device 1 includes an own vehicle position information acquisition unit 2 , a line of sight information acquisition unit 3 , a blind spot accident information acquisition unit 4 , and a notification unit 5 .

The own vehicle position information acquisition unit 2 acquires own vehicle position information indicating the current position of the own vehicle. The line-of-sight information acquisition unit 3 acquires line-of-sight information including the line-of-sight direction of the driver of the vehicle. The blind spot accident information acquisition unit 4 acquires blind spot accident information, which is information related to a blind spot accident, at a point corresponding to the current position of the own vehicle acquired by the own vehicle position information acquisition unit 2 . Based on the blind spot accident information acquired by the blind spot accident information acquisition unit 4 and the line-of-sight information acquired by the line-of-sight information acquisition unit 3, the notification unit 5 determines the line-of-sight direction of the driver of the vehicle at the point where the blind spot accident occurred. When the blind spot direction is not the blind spot direction, the driver of the own vehicle is notified of the blind spot direction.

Blind spot accidents will now be described with reference to FIGS. FIG. 2 shows an example of a blind spot accident seen from inside the vehicle. FIG. 3 shows the blind spot accident shown in FIG. 2 on a map.

In FIGS. 2 and 3, arrows indicate the line of sight of the driver. "Accident cause" indicates that the cause of the accident exists at a blind spot in the line of sight of the driver. Also, in FIG. 3, the triangular mark indicates the own vehicle. Such an accident caused by the driver's blind spot is called a blind spot accident. Also, the direction in which the cause of the blind spot accident exists as seen from the driver is called the blind spot direction.

Blind spot accidents are roughly classified into those caused by moving objects and those caused by stationary objects. Blind spot accidents caused by moving objects include, for example, a case where a bicycle jumps out of the driver's blind spot and comes into contact with the own vehicle. Blind spot accidents caused by stationary objects include, for example, the case where the vehicle comes into contact with an obstacle present in the driver's blind spot.

Next, another configuration of the driving assistance device including the driving assistance device 1 shown in FIG. 1 will be described.

FIG. 4 is a block diagram showing an example of the configuration of the driving assistance device 6 according to another configuration. It should be noted that the driving support device 6 is assumed to be mounted on the own vehicle.

The line-of-sight information acquisition unit 3 acquires line-of-sight information including the line-of-sight direction of the driver of the vehicle from a line-of-sight detection device (not shown). The line-of-sight detection device has, for example, a camera, and detects the line-of-sight direction of the driver by performing image processing of the eyes of the driver of the vehicle captured by the camera. The line-of-sight information acquisition unit 3 may detect the line-of-sight direction of the driver by image processing instead of the line-of-sight detection device.

The blind spot accident information acquisition unit 4 acquires blind spot accident information at a point corresponding to the current position of the vehicle acquired by the vehicle position information acquisition unit 2 from the accident information collection unit 8 .

The accident information collecting unit 8 is provided outside the own vehicle, and collects and stores accident information including blind spot accident information. Specifically, the accident information collection unit 8 acquires information on accidents caused by the vehicles from a plurality of vehicles including the own vehicle. The accident information includes at least the position of the point where the accident occurred and the line-of-sight direction of the driver when the accident occurred. The accident information collection unit 8 extracts and stores blind spot accidents from the acquired accident information. In this manner, the accident information collection unit 8 may store the accident information acquired from the vehicle for each type of accident.

Based on the blind spot accident information acquired by the blind spot accident information acquisition unit 4 and the line-of-sight information acquired by the line-of-sight information acquisition unit 3, the notification unit 5 determines the line-of-sight direction of the driver of the vehicle at the point where the blind spot accident occurred. When it is not in the blind spot direction, the driver of the own vehicle is notified of the blind spot direction.

The accident information generating unit 7 generates accident information including at least the position of the point where the accident occurred and the line-of-sight direction of the driver at the time of the accident when the own vehicle has caused an accident. The accident information generator 7 then transmits the generated accident information to the accident information collector 8 .

In addition, although the case where the accident information collection part 8 extracts a blind spot accident was demonstrated in FIG. 4, it does not restrict to this. For example, the blind spot accident information acquisition unit 4 may extract blind spot accident information from the accident information acquired from the accident information collection unit 8 .

Although FIG. 4 illustrates the case where the accident information collection unit 8 is provided outside the driving support device 6, the present invention is not limited to this. For example, the driving assistance device 6 may include the accident information collection unit 8 . In this case, the accident information collection unit 8 may acquire and store only the accident information related to the accident caused by the own vehicle from the accident information generation unit 7, and acquire the information related to the accident caused by the other vehicle from the other vehicle. may be stored as one or a combination thereof.

<1-2. Operation>
Below, operation|movement of the driving assistance device 6 is demonstrated. Specifically, a transmission operation for transmitting accident information when an accident occurs, and a notification operation for notifying the driver when driving in the spot where the blind spot accident occurred will be described.

<1-2-1. Transmission operation>
FIG. 5 is a flow chart showing the transmission operation of the driving support device 6. As shown in FIG. It is assumed that the transmission operation shown in FIG. 5 is executed while the own vehicle is running.

In step S11, the driving support device 6 determines whether or not the own vehicle has caused an accident, based on information obtained from a camera and sensors (not shown). If the own vehicle has caused an accident, the process proceeds to step S12. On the other hand, if the own vehicle has not caused an accident, the process of step S11 is repeated.

In step S12, the accident information generation unit 7 acquires the vehicle position information from the vehicle position information acquisition unit 2, acquires the line-of-sight information from the line-of-sight information acquisition unit 3, and detects an accident including the acquired position information and line-of-sight information. Generate information. That is, the accident information generation unit 7 acquires the position information of the location where the accident occurred from the own vehicle position information acquisition unit 2, and the accident information including the line-of-sight direction of the driver at the time of the accident from the line-of-sight information acquisition unit 3. Acquire and generate accident information containing these information. The accident information generator 7 then transmits the generated accident information to the accident information collector 8 .

<1-2-2. Notification operation>
FIG. 6 is a flowchart showing the notification operation of the driving support device 6. As shown in FIG. It should be noted that the notification operation shown in FIG. 6 is assumed to be executed while the host vehicle is running.

In step S21, the notification unit 5 determines whether the vehicle is in a blind spot based on the vehicle position information acquired by the vehicle position information acquisition unit 2 and the blind spot accident information acquired by the blind spot accident information acquisition unit 4. It is determined whether or not the point is approached. Here, "approaching" means that the own vehicle exists within a predetermined range from the point where the blind spot accident occurred. When approaching the point where the blind spot accident occurred, the process proceeds to step S22. On the other hand, if the vehicle is not approaching the point where the blind spot accident occurred, the process of step S21 is repeated.

In step S22, the notification unit 5 determines whether the driver of the vehicle is looking in the direction of the blind spot based on the line-of-sight information acquired by the line-of-sight information acquisition unit 3 and the blind spot accident information acquired by the blind spot accident information acquisition unit 4. determine whether or not Specifically, when the line-of-sight direction acquired by the line-of-sight information acquisition unit 3 and the blind spot direction acquired by the blind spot accident information acquisition unit 4 match, the notification unit 5 detects that the driver of the own vehicle indicates the direction of the blind spot. Judging by what you see. It should be noted that the line-of-sight direction and the blind-spot direction may be considered to match not only when they are completely matched, but also when the line-of-sight direction and the blind-spot direction exist within a predetermined angle range. If the driver of the own vehicle is looking in the blind spot direction, the process returns to step S21. On the other hand, if the driver of the own vehicle is not looking in the blind spot direction, the process proceeds to step S23.

In step S23, the notification unit 5 notifies the driver of the host vehicle of the blind spot direction. Specifically, the notification unit 5 displays an object indicating the blind spot direction on a HUD (Head Up Display) as shown in FIG. In the example of FIG. 7, the "!" mark is an object indicating the blind spot direction as seen from the driver.

Note that the notification unit 5 is not limited to displaying the object on the HUD as shown in FIG. 7, but may display an object indicating the blind spot direction on the map, or may notify the blind spot direction by voice.

<1-3. Effect>
According to the first embodiment, when the driver is not looking at the direction of the blind spot while traveling through the point where the blind spot accident occurred, the driver is notified of the direction of the blind spot. As a result, the line of sight of the driver can be guided in the direction of the blind spot, and the driver's attention can be drawn to the spot where the blind spot accident occurred. That is, it is possible to appropriately notify the information about the blind spot accident when traveling at the point where the blind spot accident occurred.

<Embodiment 2>
<2-1. Configuration>
FIG. 8 is a block diagram showing an example of the configuration of the driving assistance device 9 according to the second embodiment.

As shown in FIG. 8 , the driving support device 9 is characterized by including a sensor information acquisition unit 10 . Since other configurations are the same as those of the driving support device 6 shown in FIG. 4 described in Embodiment 1, detailed description thereof will be omitted here.

The sensor information acquisition unit 10 acquires sensor information, which is a detection result of the sensor, from a sensor (not shown) provided on the vehicle. The sensor detects objects present in the vicinity of the vehicle, including the blind spot direction. The object detected by the sensor may be either a moving object or a stationary object.

The notification unit 5 notifies the driver of the vehicle of the existence of the object when the driver of the vehicle cannot see the blind spot and the object detected by the sensor exists in the blind spot.

<2-2. Operation>
Among the operations of the driving assistance device 9, the transmission operation of transmitting accident information when an accident occurs is the same as the operation shown in FIG. In the following, a notification operation for notifying the driver when traveling through a point where a blind spot accident has occurred will be described.

FIG. 9 is a flow chart showing the notification operation of the driving support device 9. As shown in FIG. Note that the notification operation shown in FIG. 9 is assumed to operate while the host vehicle is running. Also, since steps S31, S36, and S37 in FIG. 9 are the same as steps S21 to S23 in FIG. 6, description thereof is omitted here. Steps S32 to S35 will be described below.

In step S32, the notification unit 5 determines whether or not the driver can check the direction of the blind spot. For example, the notification unit 5 allows the driver to check the direction of the blind spot when the blind spot at the location where the blind spot accident occurred is invisible or difficult to see for the driver of the vehicle currently traveling. may be determined to be impossible. If the driver can confirm the direction of the blind spot, the process proceeds to step S36. On the other hand, if the driver cannot confirm the direction of the blind spot, the process proceeds to step S33.

In step S33, the sensor information acquisition unit 10 acquires sensor information, which is the detection result of the sensor, from the sensor provided in the host vehicle.

In step S34, based on the sensor information acquired by the sensor information acquisition unit 10, the notification unit 5 determines whether or not there is an object in the blind spot at the point where the blind spot accident occurred. If the object exists in the blind spot, the process proceeds to step S35. On the other hand, if there is no object in the blind spot, the process returns to step S31.

It should be noted that the object existing in the above-mentioned blind spot may be an object that may interfere with the running of the own vehicle. For example, it may be determined that a moving object that is moving toward the road on which the vehicle is running is an object that may interfere with the running of the vehicle. Also, a stationary object protruding onto the road on which the vehicle is running may be determined to be an object that may interfere with the running of the vehicle.

When judging whether or not an object exists in a blind spot, the sensitivity or directivity of the sensor may be specialized to the blind spot direction, the threshold for evaluation by the sensor may be changed, or the frequency of detection by the sensor may be changed. good too. Here, when the sensor is a camera, changing the frequency of detection by the sensor means changing the frame rate of the video captured by the camera. In this way, when determining whether or not an object exists in a blind spot, monitoring by sensors may be strengthened.

In step S35, the notification unit 5 notifies the driver of the host vehicle that an object exists in the blind spot. For example, the notification unit 5 may display an object indicating that an object exists in a blind spot on the HUD or map, or may notify by voice that an object exists in a blind spot. .

<2-3. Effect>
According to the second embodiment, when the driver is not looking at the direction of the blind spot when traveling through the point where the blind spot accident occurred, the driver is notified of the direction of the blind spot and the driver can confirm the direction of the blind spot. is impossible, the direction of the blind spot is monitored by a sensor. As a result, even if the driver cannot confirm the direction of the blind spot, it is possible to quickly detect an object existing in the blind spot and notify the driver of it.

<Embodiment 3>
Embodiment 3 is characterized in that the blind spot accident information includes accident other party information indicating whether the other party of the blind spot accident is a mobile object or a stationary object. Other configurations and operations are the same as those of the driving support device 6 described in Embodiment 1 or the driving support device 9 described in Embodiment 2, and therefore detailed descriptions thereof are omitted here.

Blind spot accidents when the other party is a moving object include, for example, an accident in which a moving object jumps out of the blind spot and the own vehicle collides. Blind spot accidents when the other party is a stationary object include an accident in which the own vehicle comes into contact with a stationary object existing in the blind spot. The accident information collection unit 8 stores accident partner information indicating whether the partner of such a blind spot accident is a mobile object or a stationary object, including the blind spot accident information.

For example, the notification unit 5 in the driving support devices 6 and 9 may perform notification corresponding to each of the moving object and the stationary object based on the accident other party information. Specifically, the notification unit 5 may notify the driver of the host vehicle by display or voice that there is a possibility that a moving object or a stationary object is present in the blind spot.

Further, for example, the notification unit 5 in the driving support device 9 may switch between notifying the driver of the own vehicle and enhancing monitoring by the sensor, based on the accident partner information. At this time, the notification unit 5 may change the detection range of the sensor based on the accident other party information.

In addition, although the case where the notification part 5 changes notification based on accident other party information was demonstrated above, it does not restrict to this. The notification unit 5 may change notification to the driver of the own vehicle based on driver information including at least one of age and sex of the driver of the vehicle that caused the blind spot accident. For example, when the driver of the vehicle that caused the blind spot accident is an elderly person and the driver of the own vehicle is a young person, the notification unit 5 lowers the priority of notification to the driver of the own vehicle. may In this case, the age of the driver of the own vehicle may be registered in advance in the driving assistance devices 6 and 9, and the age of the driver may be determined by image processing the image of the driver captured by a camera (not shown). can be estimated.

As described above, according to the third embodiment, it is possible to make a more appropriate notification using the accident other party information, the driver information, or both information.

<Embodiment 4>
In Embodiments 1 and 2, the case where the driver is notified of the direction of the blind spot when the driver is not looking at the direction of the blind spot while traveling through the point where the blind spot accident occurred has been described. The fourth embodiment is characterized by notifying the driver of the blind spot direction and displaying an image of the blind spot direction. Since other configurations and operations are the same as those of the driving support device 6 described in the first embodiment or the driving support device 9 described in the second embodiment, detailed description thereof will be omitted here.

A notification unit 5 in the driving support devices 6 and 9 notifies the driver of the direction of the blind spot and displays an image of the direction of the blind spot taken by a camera (not shown) on a HUD or the like when the vehicle travels through a point where a blind spot accident has occurred.

As described above, according to the fourth embodiment, not only the direction of the blind spot but also the image of the direction of the blind spot is displayed. Therefore, more appropriate notification can be given when traveling through the point where the blind spot accident occurred.
