  The video I / F 110 is connected to the display 111 and the camera 112 and controls image display on the display 111 and image capturing on the camera 112. The display 111 outputs driving support information output as image information as part of driving support information output means described later. The display 111 displays map data around the current position of the vehicle and various data such as icons, cursors, menus, windows, characters and images. The map data displayed on the display 111 can be displayed with a mark representing the current location of the vehicle on which the driving support device 10 is mounted.

In addition, the communication I / F 113 includes a short-range communication interface that performs direct communication (vehicle-to-vehicle communication, road-to-vehicle communication) with surrounding vehicles and roadside devices without using a network. The GPS unit 114 receives radio waves from GPS satellites and outputs information indicating the current position of the vehicle. The information indicating the current position of the vehicle is, for example, latitude / longitude information.

  FIG. 2 is a block diagram illustrating a functional configuration of the driving support device 10. The driving support apparatus 10 includes a support information output unit 202, a traveling state information acquisition unit 204, a collision prediction unit 206, and an information amount control unit 208. 2, the support information output means 202 is the speaker 108 and the display 111 shown in FIG. 1, and the running state information acquisition means 204 is the camera 112, the GPS unit 114, the communication I / F 113, various sensors 115, and the like. When the CPU 101 executes various programs, the collision prediction unit 206 and the information amount control unit 208 are realized by the CPU 101 executing various programs, respectively.

  The support information output unit 202 is a so-called HMI (Human Machine Interface), and outputs driving support information that supports driving of the vehicle in a plurality of output forms. In the present embodiment, the plurality of output forms are sound output and image output, and sound output is performed by the sound output means 202a and image output is performed by the image output means 202b. The audio output unit 202a is specifically the speaker 108, and the image output unit 202b is specifically the display 111.

  The traveling state information acquisition unit 204 acquires traveling state information indicating the traveling state of the vehicle. The traveling state information acquisition means 204 is, for example, vehicle traveling speed information and current position, road width information of a road on which the vehicle is traveling, distance information between a forward traveling vehicle and a vehicle traveling in front of the vehicle, and a forward traveling vehicle. Vehicle height information. More specifically, the traveling speed information of the vehicle can be acquired as a value of a vehicle speed sensor of various sensors 115, for example. Further, the current position of the vehicle can be acquired as output information from the GPS unit 114. Further, the road width information of the road on which the vehicle is traveling can be acquired from, for example, road type information included in map information around the current position of the vehicle or a photographed image of the camera 112. Further, the distance information between the vehicle traveling ahead and the vehicle traveling ahead of the vehicle and the vehicle height information of the vehicle traveling ahead can be obtained from, for example, a photographed image of the camera 112 or radar detection results of the various sensors 115. .

  Further, the traveling state information acquisition unit 204 may acquire other vehicle information indicating a traveling state of other vehicles traveling around the vehicle. Specifically, the other vehicle information is, for example, position information, travel speed information, travel route information, and the like of the other vehicle. In this case, the traveling state information acquisition unit 204 is specifically a radar of the camera 112 or various sensors 115, for example. Moreover, if other vehicle information is acquired by vehicle-to-vehicle communication or road-to-vehicle communication using the communication I / F 113, it is possible to obtain other vehicle information on the vehicle at a position where it cannot be viewed from the vehicle.

  Furthermore, the driving state information acquisition unit 204 determines whether the vehicle and surrounding moving objects (pedestrians and bicycles) and stationary objects (electric poles, guardrails, etc.) from the images taken by the camera 112 and the radar detection results of the various sensors 115. The distance may be detected.

  The collision prediction unit 206 predicts the possibility of collision of the vehicle with another object and the predicted collision time based on the traveling state information. Other objects are, for example, other vehicles that travel around the vehicle, moving objects such as pedestrians and bicycles, and stationary objects such as utility poles and guardrails. For example, the collision prediction unit 206 predicts the position of the host vehicle after a predetermined time and the position of another object at the same time, and if the position of the host vehicle and the position of the other object are within a predetermined distance, Predict that the vehicle may collide with another object (after a predetermined time).

  The information amount control unit 208 controls the information amount of the driving support information output from the support information output unit 202 for each output form based on the driving state information acquired by the driving state information acquisition unit 204. As described above, in the present embodiment, since the plurality of output forms are audio output and image output, the information amount control unit 208 includes the information amount of the driving support information output by sound and the driving support information output by image. Control the amount of information. Hereinafter, driving support information output by voice is referred to as “voice support information”, and driving support information output by image is referred to as “image support information”.

  FIG. 3 is an explanatory diagram illustrating a difference in the amount of information of driving support information. FIG. 3 shows an image output unit 202b as the support information output unit 202, and shows an example of driving support information when the host vehicle may collide with another vehicle. 3A shows a standard state where the amount of driving support information is standard, FIG. 3B shows a state where the amount of driving support information is small, and FIG. 3C shows a state where the amount of driving support information is large. , Respectively.

  When the information amount of the driving support information shown in FIG. 3 (a) is in a standard state, a normal navigation screen MP is displayed on the image output means 202b, and then a message display M (“front intersection, approaching” of the driving support information is displayed. Please pay attention to the person. ”) Is displayed. In addition, a sign display W that calls attention with a color that draws attention, such as red or yellow, is displayed at the top of the navigation screen MP. The contents of the message display M are output as voice from the voice output means 202a.

  In a state where the amount of driving support information shown in FIG. 3B is small, a normal navigation screen MP is displayed in most areas of the image output means 202b. As the driving support information, only the sign display W is displayed at the top of the navigation screen MP. Further, in the state shown in FIG. 3A, only short audio information such as “beep”, “right, attention”, and the like is output from the audio output unit 202a. Only the voice information may be output without performing the sign display W. By suppressing the amount of driving support information in this way, it is possible to prevent the driver's attention from being directed too much toward the support information output means 202.

  In a state where the amount of driving support information shown in FIG. 3C is large, a driving support dedicated screen S is displayed on the image output means 202b instead of the normal navigation screen MP. On the driving support dedicated screen S, the position and moving direction of other vehicles that may possibly collide, the predicted collision location, and the like are displayed. Also, for example, a message such as “Caution for approaching right direction” flashes. From the audio output means 202a, the situation is described in detail, such as “a passenger is approaching from the right direction. Please decelerate”, and a collision avoidance instruction is output as audio. By increasing the amount of driving support information in this way, the driver can grasp the current situation in more detail and can quickly grasp the specific action that the driver should take. .

  For example, when the traveling speed of the vehicle is equal to or higher than a predetermined speed, the information amount control unit 208 reduces the information amount of the image support information as compared with the case where the traveling speed of the vehicle is less than the predetermined speed. This is because if the driver turns his / her line of sight toward the display 111 when the traveling speed is high, there is a possibility of inducing a sideward driving, which is not preferable. In this case, the information amount control unit 208 may increase the information amount of the voice support information, for example, in order to supplement the information amount of the image support information.

  Further, the information amount control means 208 may provide voice support information when the road width of the road on which the vehicle is traveling is less than a predetermined length than when the road width of the road on which the vehicle is traveling is greater than or equal to the predetermined length. And increase the amount of image support information. There is a lot of blind spots in the back alleys where the roads are narrow and the need for driving assistance is high. Moreover, since it is highly possible that the vehicle is traveling slowly on such a narrow road, even if the driver turns his / her line of sight toward the display 111, it is considered that the risk is relatively low. For this reason, the information amount control means 208 increases the information amount of the driving support information to be output so that the information can be reliably transmitted to the driver.

  Further, the information amount control means 208 is configured such that when the inter-vehicle distance with the forward traveling vehicle is less than the predetermined distance and the vehicle height of the forward traveling vehicle is greater than or equal to the predetermined height, the inter-vehicle distance with the forward traveling vehicle is the predetermined distance or more. The amount of driving support information output by sound and image is increased as compared with the case where the vehicle height is less than a predetermined height. The case where the distance between the front traveling vehicle is less than the predetermined distance is a case where the distance between the front traveling vehicle and the front traveling vehicle is clogged, and the case where the height of the front traveling vehicle is equal to or higher than the predetermined height is This is the case for large vehicles such as trucks and buses. In this case, the driver's front view is likely to be blocked by the forward traveling vehicle, and the driver needs to be informed of the situation ahead. For this reason, the information amount control means 208 increases the information amount of the driving support information to be output so that the front situation can be reliably transmitted to the driver. Note that if the distance between the vehicle and the forward traveling vehicle is short and it is not preferable for the driver to turn his / her line of sight toward the display 111, the amount of information only for the voice support information may be increased.

  In addition, if the lighting state of a traffic light provided in front of the traveling direction of the vehicle is output as driving support information, it is difficult for the driver to check the lighting state of the traffic light because the field of view is blocked by the forward traveling vehicle. Safety can be improved in such cases. In this case, the lighting state of the traffic signal is received from, for example, a roadside device provided near the traffic signal.

  In addition, when the collision prediction unit 206 determines that there is a possibility that the vehicle collides with another object, the information amount control unit 208 determines that when the remaining time until the collision prediction time is less than the predetermined time, The amount of driving assistance information output by voice and images is less than when there is no possibility of colliding with an object, and the vehicle can collide with another object when the remaining time until the collision prediction time is longer than the predetermined time The amount of driving support information output by voice and image is increased compared to the case where there is no sex.

  Specifically, for example, when the remaining time until the collision prediction time is short, only a buzzer sound or a short sound (for example, “vehicle approach, attention”, etc.) is output. That is, the driving support information is output in the form as shown in FIG. This is because it is necessary to direct the driver's attention directly to an object with a possibility of collision rather than the support information output unit 202. On the other hand, if the remaining time until the predicted collision time is long to some extent, for example, the display 111 displays the positional relationship between the object that may collide and the vehicle, or “the vehicle is approaching from the right. Please output a voice message or message display. That is, the driving support information is output in the form as shown in FIG. This is to assist the driver so that the driver can grasp the position of the object that may possibly collide and avoid the collision. In FIG. 3, the information amount of the driving support information when there is no possibility that the vehicle collides with another object corresponds to FIG.

  In addition, for example, the travel state information acquisition unit 204 acquires the travel route history information of the vehicle, and the information amount control unit 208 determines the travel frequency of the traveling road based on the travel route history information. The amount of driving support information may be reduced on roads with high frequency, and the amount of driving support information may be increased on roads with low driving frequency. This is because, on roads with high driving frequency, the driver is likely to know the traffic situation of the road and the need for driving support information is low, whereas on roads with low driving frequency, the road This is because there is a high possibility that the driver cannot grasp the traffic situation of the vehicle and there is a high need for driving support information.

  FIG. 4 is a flowchart showing processing by the driving support device 10. In the flowchart of FIG. 4, the driving support device 10 acquires the driving state information of the host vehicle by the driving state information acquisition unit 204 (step S <b> 401). At this time, the driving state information acquisition unit 204 detects other vehicle information indicating the driving state of the other vehicle and the distance from the surrounding objects in addition to the information such as the speed of the host vehicle.

  The driving assistance device 10 returns to step S401 and continues to acquire the traveling state information until it is time to output the driving assistance information (step S402: No). The timing to output the driving support information is, for example, a case where the collision prediction unit 206 determines that the vehicle may collide with another object. When it is time to output the driving support information (step S402: Yes), the driving support device 10 determines the information amount of the driving support information by the information amount control means 208 (step S403). At this time, the information amount control unit 208 determines the information amount based on the running state information acquired in step S401. Further, the information amount control unit 208 determines the information amount for each of a plurality of output forms of driving support information (in this embodiment, sound and image).

  The information amount control unit 208 generates output data (voice data or image data) to be output from the support information output unit 202 based on the information amount determined in step S403 (step S404). Then, driving support information is output from the support information output means 202 using the output data generated in step S404 (step S405), and the processing according to this flowchart ends.

  As described above, the driving support device 10 according to the embodiment controls the amount of driving support information for each output form based on the driving state information of the vehicle. Thus, the driver can easily grasp the content of the driving support information. In addition, it is possible to reduce the time for the driver to pay attention to the output driving assistance information and to concentrate on driving. In addition, since the driving support device 10 outputs the driving support information by voice output and image output, the driver can obtain the driving support information by visual and auditory sense, and make it easier to grasp the content of the driving support information. Can do.

  Moreover, the driving assistance apparatus 10 reduces the information amount of the driving assistance information output with an image, when the driving speed of a vehicle is more than predetermined speed. As a result, the time for the driver to turn his / her line of sight toward the support information output means can be shortened to prevent side-by-side driving. In addition, when the road width of the road on which the vehicle is traveling is less than a predetermined length, the driving support device 10 increases the amount of driving support information output by sound and image. This makes it possible to reliably transmit information to the driver by increasing the amount of driving support information in situations where the need for driving support is high, such as when driving on a road with a narrow road width and many blind spots. .

  In addition, the driving assistance device 10 increases the amount of information of driving assistance information output by sound and image when the inter-vehicle distance with the forward traveling vehicle is less than a predetermined distance and the vehicle height of the forward traveling vehicle is greater than or equal to the predetermined height. . As a result, when the forward vehicle is a large vehicle and the distance between the vehicles is short, the driver's front view is obstructed. Can communicate.

  Further, when there is a possibility that the vehicle collides with another object, the driving support device 10 reduces the amount of driving support information output by voice and image when the remaining time until the collision prediction time is less than a predetermined time. When the remaining time until the collision prediction time is equal to or longer than the predetermined time, the amount of driving support information output by sound and image is increased. As a result, when the remaining time until the collision prediction time is short, the driver's attention is directed directly to the object with the possibility of collision instead of the support information output means so that the collision avoidance driving operation can be immediately taken. can do. In addition, when the remaining time until the predicted collision time is long to some extent, it is possible to assist the driver so as to reliably grasp the position of an object that may collide and avoid the collision.
