Description

  The present invention relates to an information providing apparatus that is mounted on a vehicle and provides information to a driver.

  Conventionally, there is an information providing apparatus that is mounted on a vehicle and provides information to a driver. The information provided includes, for example, map information representing a map in the vicinity of the host vehicle, building information representing a building (shop) or the like to be marked on the map, route information representing a route to the destination, traffic congestion, and the like. There are route change information provided when the route to the ground is changed, advertising information indicating that shops and tourist spots are nearby, and e-mail.

  However, if such information is provided while the vehicle is running (when the driver is driving), the driver may not be able to check the information easily or may interfere with safe driving for the driver.

  A conventional technique in view of such a problem is disclosed in Patent Document 1, for example. Specifically, Patent Document 1 discloses an information providing device (vehicle map display device) that restricts information to be provided when the host vehicle is traveling.

JP 2004-317418 A

  However, even in the information providing device disclosed in Patent Document 1, information is provided immediately without being limited to the state of the host vehicle (driver), and thus the above problem cannot be solved completely.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a technique for providing easy-to-understand information to a driver without hindering safe driving.

  In order to achieve the above object, the present invention adopts the following configuration.

An information providing apparatus according to the present invention includes:
An information providing device mounted on a vehicle and providing information to a driver,
A final provision point determination means for determining a final provision point, which is a point where information should be finally provided, according to the content of the information;
A section for determining whether or not there is an expected section where the state of the host vehicle is expected to meet a predetermined preset condition between the final provision point and the current position of the host vehicle Situation judgment means,
When it is determined that there is the predicted section, the host vehicle state determination unit that determines whether the state of the host vehicle conforms to a preset condition;
An information providing means for providing information when the state of the host vehicle meets a preset condition in an expected section, or after the predicted section;
It is characterized by having.

In the information providing apparatus according to the present invention, it is determined whether or not there is an expected section that is expected to meet the preset condition between the point where the information should be finally provided and the current position of the host vehicle. to decide. Then, information is provided when the state of the host vehicle meets the preset condition within the predicted section or after the predicted section. That is, the provision of information is delayed until after receiving or during the expected interval. Furthermore, when the state of the host vehicle meets the preset condition within the expected section, information is provided at that timing. As a result, it is possible to provide information at a timing at which the driver can check the information with a margin, so that it is possible to provide information that is easy to understand without impeding safe driving for the driver. Note that the predicted section is preferably a section in which the driver is expected to be in a state where information can be confirmed with sufficient margin (information confirmable state).

  When the state of the host vehicle does not meet the preset condition within the predicted section, the information providing means stores the information by the time the host vehicle passes through the predicted section and reaches the final provision point. Preferably it is provided. By adopting such a configuration, it is possible to provide information within a section where information should be provided even when the state of the host vehicle does not meet the preset condition within the predicted section. .

  When it is determined that there is no predicted section, it is preferable that the information providing unit provides the information until the own vehicle reaches the final provision point. With such a configuration, even when it is determined that there is no expected section, it is possible to provide information within a section where information should be provided.

  The preset condition is preferably that the speed of the host vehicle is less than a predetermined speed. Moreover, it is preferable that the preset condition is that the host vehicle is stopped. When the speed of the host vehicle is less than a predetermined speed (for example, 10 km / h), the driver can check the information with a margin as compared with the case of traveling at a speed higher than the predetermined speed. If the vehicle is stopped, the driver can confirm the information more reliably. Therefore, by defining the preset conditions as described above, it is possible to provide information at a timing at which the driver can check the information with a margin, so that it does not interfere with and understand safe driving. Easy to provide information.

  The predicted section is based on at least one of information indicating traffic jam between the final provision point and the current vehicle position, information indicating a traffic signal installation position, and information indicating a stop point position. It is preferable that the interval is determined. If there is a traffic jam, a traffic light, a stopover point, etc. between the final provision point and the current position of the host vehicle, the host vehicle is expected to decrease in speed or stop. Therefore, the expected section is determined based on information indicating traffic jam (traffic jam information), information indicating traffic signal installation position (signal traffic position information), information indicating the location of the stop (location information of the stop), etc. Thus, it is possible to easily define the prediction interval.

  It is preferable that the preset condition is that the host vehicle is traveling on a road on which the host vehicle is easy to travel. Compared to narrow roads, intricate roads (roads with many sharp curves), roads without sidewalks, and the like, roads such as wide roads, straight roads, roads with sidewalks and the like are easier to drive. And when driving on such a road that is easy to travel, the driver can check the information with a margin as compared to when driving on a road that is difficult to travel. Therefore, by defining the preset conditions as described above, it is possible to provide information at a timing at which the driver can check the information with a margin, so that it does not interfere with and understand safe driving. Easy to provide information.

The predicted section is preferably a section of a road that is easy to travel. As described above, the driver can check the information more easily when traveling on a road that is easier to travel than when traveling on a road that is difficult to travel. Therefore, the predicted section can be easily defined by setting the section of the road that is easy to travel as the predicted section.

  Further, the present invention may be regarded as an information providing apparatus having at least a part of the above means, an information providing method including at least a part of the above processing, an information providing program for realizing such a method, It can also be understood as a storage medium storing a program. Further, the present invention may be regarded as a vehicle having at least a part of the above means. Each of the above means and processes can be combined with each other as much as possible to constitute the present invention.

  According to the present invention, it is possible to provide a technique for providing information that is easy to understand and does not hinder safe driving.

  Exemplary embodiments of the present invention will be described in detail below with reference to the drawings. The information providing apparatus according to the present embodiment is mounted on a vehicle and provides information to a driver.

<Device configuration>
First, the configuration of the information providing apparatus according to the present embodiment will be described with reference to FIG. FIG. 1 is a block diagram illustrating functions and configurations of the information providing apparatus according to the present embodiment. As illustrated in FIG. 1, the information providing apparatus 100 according to the present embodiment includes an information acquisition and generation unit 101, an information provision timing processing unit 102, a display unit 103, and the like.

  The information acquisition and generation unit 101 acquires and generates information. For example, the information acquisition / generation unit 101 acquires information (such as e-mail, advertisement information indicating that a shop or a sightseeing spot is nearby) from the outside (such as a roadside machine). In addition, the information acquisition / generation unit 101 generates information according to the state of the host vehicle, the surrounding situation, and the like. Specifically, when information indicating traffic conditions such as traffic jams and traffic closures is acquired from the outside, and the travel route to the destination (hereinafter referred to simply as “route”) is changed, the route is changed. Generate route change information to represent. Further, when the fuel of the host vehicle becomes less than a predetermined amount, refueling warning information indicating that the fuel has been reduced is generated. In addition, as acquired information and generated information, map information representing a map in the vicinity of the host vehicle, building information representing a building (shop) etc., which is a landmark on the map, route information representing a route to the destination and so on.

  The information provision timing processing unit 102 provides the information acquired and generated by the information acquisition and generation unit 101 at a predetermined timing (outputs to the display unit 103). As shown in FIG. 1, the information provision timing processing unit 102 includes a final provision point determination unit 111, a section status determination unit 112, a host vehicle state determination unit 113, an information provision unit 114, and the like.

  For example, when information is acquired or generated by the information acquisition and generation unit 101, the final provision point determination unit 111 determines the final provision point that is the point where the information should be finally provided according to the content of the information. decide. A specific example of the final provision point will be described in detail later.

  The section status determination unit 112 is configured so that the state of the host vehicle satisfies a preset condition determined in advance between the last provided point determined by the final provided point determining unit 111 and the current position of the host vehicle. It is determined whether or not there is an expected interval. In addition, it is preferable that an estimated area is an area where it is expected that the driver can check information with a margin (information checkable state). The position (position information) of the host vehicle may be calculated based on, for example, a GPS signal received by a receiver (not shown). Specific examples of the preset condition and the prediction interval will be described later in detail.

  The own vehicle state determination unit 113 determines whether or not the state of the own vehicle meets the preset condition. Specifically, the host vehicle state determination unit 113 determines whether or not the state of the host vehicle meets the preset condition when the section state determination unit 112 determines that there is an expected section.

  The information providing unit 114 provides information at a timing corresponding to the determination result of the section state determination unit 112 and the determination result of the own vehicle state determination unit 113 (outputs to the display unit 103). Specifically, information is provided when the state of the host vehicle meets the preset condition in the predicted section or after the predicted section. In the present embodiment, information is provided at a timing when the host vehicle state determination unit 113 determines that the host vehicle state matches the preset condition, and the host vehicle state meets the preset condition within the expected section. If not, information is provided at the timing when the vehicle passes the final point of the predicted section (the predicted section end closest to the final provision point). Further, when the section situation determination unit 112 determines that there is no predicted section, immediately after the information acquisition and generation unit 101 acquires and generates information (that is, at the same timing as the conventional timing), the information is stored. provide.

  The display unit 103 displays information sent from the information provision timing processing unit 102 (information providing unit 114). Thereby, information is provided (presented) to the driver. The display unit 103 may be an existing display device such as a liquid crystal display, a plasma display, or an organic EL display.

<Information provision processing>
Next, a flow of processing until information is provided in the information providing apparatus 100 according to the present embodiment will be described with reference to FIG. FIG. 2 is a flowchart showing a flow of processing until information is provided in the information providing apparatus 100 according to the present embodiment.

  First, when the information acquisition and generation unit 101 acquires or generates information, that is, when there is information to be provided (step S201: YES), the final provision point determination unit 111 determines whether the information is provided, A final provision point is determined (step S202).

  Next, the section status determination unit 112 determines whether or not there is an expected section between the final provision point and the current position of the host vehicle where the state of the host vehicle is expected to meet the preset condition. Judgment is made (step S203). If it is determined that there is an expected section (step S203: YES), the process proceeds to step S204. If it is determined that there is no predicted section (step S203: NO), the process proceeds to step S205.

  In step S204, the host vehicle state determination unit 113 determines whether or not the state of the host vehicle conforms to preset conditions. If the state of the host vehicle meets the preset condition (step S204: YES), the process proceeds to step S205, and if the state of the host vehicle does not match the preset condition (step S204: NO). The process proceeds to step S206.

  In step S205, the information acquired or generated in step S201 is provided. Specifically, when the information providing unit 114 outputs the information acquired or generated in step S201 to the display unit 103, the information is displayed on the display unit 103. Thereby, the information acquired or generated in step S201 is provided to the driver.

In step S206, the host vehicle state determination unit 113 determines whether or not the host vehicle has passed the final point of the predicted section. If the host vehicle has passed the final point of the predicted section (step S206: YES), the process proceeds to step S205, and if the host vehicle has not passed the final point of the predicted section (step S206: NO), step Return to S204. Whether or not the host vehicle has passed the final point of the predicted section may be determined from, for example, the predicted section and position information of the host vehicle. The process in step S206 may be performed by a function other than the own vehicle state determination unit 113. The information providing apparatus may further include another function for performing the process of step S206.

<Specific examples of final provision points, preset conditions, and forecasted sections>
Hereinafter, specific examples of the final provision point, the preset condition, and the predicted section will be described in detail.

(Example of final delivery point)
The final provision point can be classified according to the type of information. Hereinafter, if the information is route change information indicating that the route to the destination has been changed, or if the information is advertising information indicating that shops or tourist spots are nearby, the fuel of the vehicle is An example of the last provision point in the case of refueling warning information indicating that it has decreased and in the case of mail will be described.

-If the information is route change information If the information is route change information, the final provision point may be set before the point where the difference between the route before the change and the route after the change occurs.

  For example, as shown in FIG. 3, it is assumed that a traffic jam has occurred in the section 32 in the route to the destination (old route 31a). In that case, the route to the destination is changed to a route (new route 31b) that detours before the section 32. In the example of FIG. 3, the old route 31 a and the new route 31 b are different routes after the intersection 33 before the section 32. If the route change information is provided to the driver at least by the intersection 33, the driver can avoid traffic congestion by checking the information (even if the route change information is provided after the intersection 33, it does not make sense. Absent). Therefore, in the example of FIG. 3, the position of the intersection 33 is set as the final provision point.

  Since it takes some time for the driver to confirm the route change information and move to the actual operation (handle operation to proceed with the changed route), the route before and after the change A point that is somewhat before the point (branch point) where the difference occurs (for example, a point 50 m before the branch point, a point expected to arrive 30 seconds before the scheduled time to reach the branch point, etc.) It is preferable to use it as a provision point.

・ When the information is advertising information When the information is advertising information, the final provision point may be set before the location of the shop or tourist spot.

  For example, as shown in FIG. 4, it is assumed that the host vehicle is traveling on a route passing through the tourist spot 41 (or a route to the tourist spot 41). In that case, if advertisement information is provided up to the sightseeing spot 41, the driver can grasp the existence of the sightseeing spot 41 by checking the information and can easily stop at the sightseeing spot 41 (sightseeing spot 41). If the advertisement information is provided later than that, it will be difficult to stop at the sightseeing spot 41). Therefore, in the example of FIG. 4, the location of the tourist spot 41 is set as the final provision point.

  Since it takes some time for the driver to confirm the advertisement information before moving to the actual operation (handle operation to enter the store), a point somewhere before the location of the store or tourist spot ( For example, it is preferable to set a point 50 meters before, a point 30 seconds before, etc.) as the final providing point.

When the information is refueling warning information When the information is refueling warning information, as shown in FIG. 5, a predetermined distance from a point where the fuel becomes less than a predetermined amount (for example, less than 3 liters). A point 52 that is 51 ahead (for example, a point that is 10 km away or a point that is 10 minutes away) may be the final provision point. Of course, the final supply point is a point within a range where the remaining fuel can be traveled.

  However, if the information is the refueling warning information and the point as described above is the final provision point, there may be no refueling place (gas station or the like) near the final provision point. Therefore, the location of the refueling place existing ahead of the point where the fuel is less than a predetermined amount in the route through which the host vehicle passes may be set as the final providing point.

  For example, it is assumed that the fuel of the host vehicle is little remaining at the position 61 as shown in FIG. In that case, if the refueling warning information is provided up to the refueling place 62 existing ahead of the position 61 in the route on which the host vehicle is traveling, the driver can recognize the existence of the refueling place 62 by confirming the information. You can stop at the refueling place 62. As a result, fuel can be supplied without running out of fuel. Therefore, in the example of FIG. 6, the position of the refueling place 62 is set as the final point.

  In addition, when the final provision point is defined in this way, it takes some time until the driver moves to the actual operation (handle operation to enter the refueling place) after confirming the refueling warning information. It is preferable that a point a little before the refueling place (for example, a point 50 m before or a point 30 seconds before) is set as the final providing point.

・ If the information is mail If the information is mail, a point that is a predetermined distance away from the point where the mail is received (for example, a point 15 km away or a point 15 minutes ahead) do it. Note that the final provision point may be varied according to the importance of the mail. For example, when a highly important mail is received, a point 2 km ahead is set as the final providing point, and when a low importance mail is received, a point 30 km ahead may be set as the final providing point.

(Example of preset conditions)
The preset condition can be defined based on, for example, the speed of the host vehicle and the ease of running on the road on which the host vehicle is traveling.

  Specifically, when the speed of the host vehicle is less than a predetermined speed, the driver can check the information with a margin as compared to when the vehicle is traveling at a speed higher than the predetermined speed. Therefore, by setting the speed of the host vehicle to be less than a predetermined speed (for example, 15 km / h) as a preset condition, information can be presented at a timing at which the driver can check the information with a margin (such as that) At this timing, the process proceeds from step S204 to step S205 (step S204: YES). Therefore, it is possible to present information that is easy to understand and does not hinder safe driving.

  If the vehicle is stopped, the driver can confirm the information more reliably. Therefore, by setting the fact that the host vehicle is stopped as a preset condition, it is possible to provide information at a timing at which the driver can confirm the information with more margin. That is, it is possible to provide the driver with more reliable information that does not hinder safe driving and is easy to understand.

In addition, a vehicle such as a wide road, a straight road, or a road with a sidewalk is easier to travel than a narrow road, a complicated road (a road with many sharp curves), or a road without a sidewalk.
And when driving on such a road that is easy to travel, the driver can check the information with a margin as compared to when driving on a road that is difficult to travel. In view of this, it is possible to provide information at a timing at which the driver can check the information with a margin by setting the condition that the vehicle is traveling on an easy-to-run road as a preset condition. Therefore, it is possible to provide information that is easy to understand and does not interfere with safe driving.

(Example of forecast interval)
The predicted section includes, for example, information (congestion information) indicating traffic jam between the final provision point and the current vehicle position, information indicating traffic signal installation location (signal traffic location information), and the location of the stop point. It can be defined based on at least one piece of information to be represented (position information of the stop-off point). The stop point is a point (a location of a shop or the like) where the driver stops between the final provision point and the current point.

  Specifically, as shown in FIGS. 7A to 7C, when there is a traffic jam between the final provision point and the current vehicle position, the vehicle reduces its speed or stops due to the traffic jam. Is expected to. Therefore, the expected section can be determined based on the traffic jam information. For example, a section where the traffic jam occurs between the final provision point and the current vehicle position (the traffic jam section) may be set as the predicted section. If there are a plurality of traffic congestion sections between the final provision point and the current position of the vehicle, the traffic congestion sections may be assumed to be the predicted sections (sections 71 to 73) as shown in FIG. 7A. As shown in FIG. 7B, one predicted section (section 74) (one between the last provision point and the current vehicle position) may be defined for a plurality of traffic congestion sections. As shown in FIG. 7C, a specific traffic jam section among a plurality of traffic jam sections may be set as the predicted section (section 75). The specific traffic jam section may be the traffic jam section closest to the final provision point or the traffic jam section farthest from the final provision point. There may be a plurality of specific traffic congestion sections. The predicted section may be defined in any way as long as it is based on traffic jam information between the final provision point and the current vehicle position.

  In addition, as shown in FIGS. 8A to 8C, when there is a traffic light between the final provision point and the current position of the host vehicle, the host vehicle decreases the speed by the signal (such as a red signal) or It is expected to stop. Therefore, the predicted section can be determined based on the traffic signal installation position information. For example, a section (including the installation position of the traffic light) from the installation position of the traffic light to a short distance (for example, 100 m) may be set as the predicted section. In addition, when there are a plurality of traffic lights between the final provision point and the current position of the host vehicle, an expected section (sections 81 to 83) may be determined for each traffic signal as shown in FIG. 8A. As shown in FIG. 8B, one predicted section (section 84) may be defined for a plurality of traffic lights (one between the last provision point and the current vehicle position). As shown in FIG. 8C, an expected section (section 85) may be determined for a specific signal among a plurality of signals. The specific traffic light may be a traffic light closest to the final provision point or a signal farthest from the final provision point. A traffic signal that causes the host vehicle to stop may be detected based on the switching timing of the traffic signal and the traveling speed of the host vehicle, and the detected traffic signal may be used as a specific traffic signal. There may be a plurality of specific traffic lights. The predicted section may be defined in any way as long as it is based on the traffic signal installation position information between the final provision point and the current vehicle position.

Also, as shown in FIGS. 9A to 9C, when there is a stop point between the final provision point and the current position of the host vehicle, the host vehicle drops in speed by stopping at the stop point or It is expected to stop. Therefore, the expected section can be determined based on the location information of the stopover point. For example, a section (including the position of the drop-in point) from the position of the drop-in point to the front by a predetermined distance (for example, 200 m) may be set as the predicted section. In addition, when there are a plurality of stop points between the final provision point and the current position of the vehicle, an expected section (sections 91 to 93) may be determined for each stop point as shown in FIG. 9A. .
As shown in FIG. 9B, one predicted section (section 94) may be defined for a plurality of stop points (one between the final provision point and the current position of the vehicle). As shown in FIG. 9C, an expected section (section 95) may be defined for a specific stop point among a plurality of stop points. The specific stop point may be a stop point closest to the final providing point or a stop point farthest from the final providing point. There may be a plurality of specific stop points. The predicted section may be defined in any way as long as it is based on the location information of the stop point between the final provision point and the current vehicle position.

  In addition, as described above, the driver can check the information more easily in the state where the vehicle is traveling on the easy-to-run road than in the state where the vehicle is difficult to travel. Therefore, it is good also considering the area of the road which is easy to drive | work as an estimated area.

  If the prediction interval is defined as illustrated above, the prediction interval can be easily defined.

  As described above, the information providing apparatus according to the present embodiment is a section that is expected to meet the preset condition between the point where the information is to be finally provided and the current position of the host vehicle. Judge whether there is. Then, information is provided when the state of the host vehicle meets the preset condition within the predicted section or after the predicted section. That is, the provision of information is delayed until after receiving or during the expected interval. Furthermore, when the state of the host vehicle meets the preset condition within the expected section, information is provided at that timing. As a result, information can be provided at a timing at which the driver can confirm the information with a margin, and thus information that does not hinder safe driving and is easy to understand can be provided to the driver.

  In the present embodiment, a configuration is provided in which information is provided when the state of the host vehicle does not meet the preset condition within the predicted section, or when the section status determination unit 112 determines that there is no predicted section. However, in such a case, there is a high possibility that the driver cannot confirm the information with a margin, so the information need not be provided.

  In this embodiment, when the state of the host vehicle does not meet the preset condition in the predicted section, the information is provided at the timing when the host vehicle passes the final point of the predicted section. The timing of providing information in such a case is not limited thereto. If the state of the vehicle does not meet the preset conditions in the expected section, if the information is provided before the vehicle reaches the final provision point after passing the predicted section, the section where the information should be provided Information can be provided within.

  In the present embodiment, when the section situation determination unit 112 determines that there is no predicted section, the information acquisition and generation unit 101 provides information immediately after the information is acquired and generated. The timing of providing information in such cases is not limited thereto. If the information is provided by the time the host vehicle reaches the final provision point, the information can be provided in the section where the information should be provided.

  If the information is a highly important mail or an urgent mail (such as a mail with a reading deadline), the information may be provided immediately after reception without performing the processing shown in FIG.

In addition, it is preferable that the own vehicle receives or stores information (table or map) associated with ease of travel for each road from the outside. Thereby, it can be easily determined whether or not the road on which the host vehicle is traveling is an easy road. In addition, the host vehicle may transmit its own position information to the outside (a management center that manages the ease of running on the road, etc.), and may acquire the ease of running on the road on which the host vehicle is traveling from the management center. Even in such a configuration, it is possible to easily determine whether or not the road on which the host vehicle is traveling is an easy road.

  The ease of running on the road may be determined by the manufacturer's standards or may be determined by the regional standards. It may be determined based on the ease of driving map of the Ministry of Land, Infrastructure, Transport and Tourism. For example, in the run ease map of the Ministry of Land, Infrastructure, Transport and Tourism, a road having a run rank of B or higher may be an easy road.

  The various predetermined values described above may be any values as long as the effects of the invention are achieved, and may be set as appropriate according to the preference of the user or manufacturer.

  In the present embodiment, the information is displayed (provided) to the driver by being displayed on the display unit. However, the information is provided to the driver by sound, light, or a combination of them (video, sound, light). It may be provided. When providing information by light, for example, a light emitting diode may be applied instead of the display unit. When providing information by sound or voice, for example, a speaker or the like is applied instead of the display unit. do it.
