Embodiment 1 FIG.
FIG. 1 is a block diagram showing the configuration of the driving support apparatus according to Embodiment 1 of the present invention, and shows navigation device 1 that functions as the driving support apparatus according to Embodiment 1. FIG.
In FIG. 1, a navigation device 1 is a navigation device brought into or mounted on a vehicle, and includes a position detection unit 2, an acceleration / azimuth detection unit 3, a map database 4, a limited range database 5, an information collection unit 6, and an arithmetic processing unit. 7, a DRAM (Dynamic Random Access Memory) 8, a display unit 9, an input unit 10, and an audio output unit 11.

The position detector 2 is a position information acquisition unit that acquires vehicle position information. For example, it is a processing unit that analyzes GPS radio waves received from GPS satellites via an in-vehicle GPS (Global Positioning System) antenna and acquires position information of the own vehicle.
The acceleration / azimuth detection unit 3 is a travel information acquisition unit that acquires travel information indicating the traveling direction of the vehicle and the vehicle speed. For example, the acceleration of the vehicle is detected by a gyro or the like, and information indicating the traveling speed of the vehicle is acquired from the acceleration in the longitudinal direction of the vehicle. In addition, a geomagnetic sensor that detects the traveling direction (traveling direction) of the vehicle from the geomagnetism is used.

The map database 4 is a database in which map data including facility information and road information is registered. For example, the map database 4 is constructed in a hard disk device included in the navigation device 1, an SD card that can be read appropriately by the arithmetic processing unit 7, a USB memory, or the like. The
The map database 4 may not be provided in the navigation device 1 but may be constructed in an external map data server that can collect map data by the information collecting unit 6.

  The limited range database 5 is a database in which a limited range that is a road situation in which the traveling state of a vehicle should be limited in accordance with time elements including day of the week, season, and time zone is registered in association with map data. Similarly to the map database 4, the limited range database 5 is also constructed in, for example, a hard disk device included in the navigation device 1, an SD card that can be appropriately read out by the arithmetic processing unit 7, or a USB memory.

The information collection unit 6 is a communication device that collects information by communicating with an external device, and particularly functions as a peripheral information acquisition unit that acquires peripheral information of a road on which the vehicle travels.
The road periphery information includes, for example, traffic jam information, facility information in the traveling direction of the vehicle, and regional information. As the facility information, information that can predict the congestion situation of vehicles and the traffic situation of pedestrians is acquired. For example, there is information such as an event held when the vehicle is traveling. The area information is area information that can predict the road surface condition, and includes, for example, weather information of an area in the traveling direction of the vehicle.

The arithmetic processing unit 7 is an arithmetic processing unit that executes various arithmetic processes of the navigation device 1.
In addition, the arithmetic processing unit 7 drives the driving action to be taken in the road condition according to the time element at the time when the vehicle is expected to reach the limit range based on the position information of the vehicle, the travel information, and the registered contents of the limit range database. Functions as a control unit for determining
For example, the arithmetic processing unit 7 uses the vehicle position information acquired by the position detection unit 2 and the traveling information (vehicle traveling direction and traveling speed) acquired by the acceleration / direction detection unit 3 while the vehicle is traveling. The registered contents of the limit range database 5 are always searched to check whether the vehicle is moving toward the limit range, and whether the vehicle has reached the position range of a predetermined distance or time up to the limit range.
When the vehicle reaches a position range of a predetermined distance or time to the limit range, the arithmetic processing unit 7 reaches the limit range from the current position using the current position of the vehicle, travel information, and map data corresponding to the limit range. Calculate the expected time. Subsequently, the arithmetic processing unit 7 refers to the limit range database 5 to determine a time element corresponding to an expected time at which the vehicle arrives, that is, a road condition of the limit range in the day of the week, season, and time zone.
Based on the determined road conditions, the arithmetic processing unit 7 refers to the driving action table data in which the driving actions that the vehicle should take in various road conditions, and determines the corresponding driving action.
The driving action table data may be set in advance in the arithmetic processing unit 7 or may be set by the user using the input unit 10.

The DRAM 8 is a memory that stores data generated by the arithmetic processing by the arithmetic processing unit 7.
The display unit 9 is an information presenting unit that displays information on the screen and presents it to the driver, and the display processing is controlled by the arithmetic processing unit 7. For example, a road map near the vehicle position is displayed as the navigation screen, or the driving action determined by the arithmetic processing unit 7 is displayed on the screen.
The voice output unit 11 is an information presentation unit that outputs information to the driver and presents it to the driver. The arithmetic processing unit 7 controls the voice output process. For example, it is composed of an in-vehicle speaker and audio output software.

The input unit 10 is an input unit that accepts an input operation by a user, and includes, for example, input hardware such as operation keys, operation buttons, and a touch panel, and software that outputs an input signal input thereto to the arithmetic processing unit 7. Consists of
The processing of registering the contents of the limited range database 5 using this input unit 10 is possible, and the driving behavior in the running state to be taken in the road conditions in the limited range can be set in the arithmetic processing unit 7.

2 to 4 are diagrams showing the contents of the limited range database in the first embodiment.
The data shown in FIG. 2 indicates a limit range in which congestion of vehicles and traffic of people increase according to time elements including days of the week, seasons, and time zones due to the existence of facilities such as schools.
For example, as shown in FIG. 2, the “elementary school 1” includes ranges 1, 2, 3, as road ranges in which the congestion of vehicles and traffic of people increase beyond a predetermined threshold according to the time of day and the day of the week. Are registered, and each road range is defined in association with road data (road link) of the map data. These data can be obtained using the results of road surveys on congestion of vehicles and traffic of people.

Even if it is a road near the school, if it is in another school district, there may be no pedestrians attending school depending on the time of day. Also, if there are schools or other facilities near the main road or highway, it is considered that there are no pedestrians on these roads. Therefore, it is not appropriate to simply make a determination based on the distance from the facility.
For example, on a school road near a school, it is assumed that there is a lot of traffic in the school attendance time zone (for example, 8: 00 to 8:30), and it is necessary to always limit the driving state of the vehicle in this time zone. . On the other hand, on school roads that are far from school, it is assumed that there will be a lot of traffic in the time zone earlier than the start time (for example, 7: 45-8: 15) in consideration of the walking speed of pedestrians attending school. It is preferable to limit the traveling state of the vehicle in a time zone different from the road.

The data of FIG. 3 shows the road range where the road surface condition needs to lower the vehicle speed than the original speed limit for each location according to the time element including the season and the time zone.
For example, in “place 1” such as a mountain, as shown in FIG. 3, ranges 1, 2, 3,... Are registered as road ranges where the road surface freezes according to the season and time zone. Are specified in association with road data (road links) of the map data.
On mountain roads, fog is likely to occur in the early morning hours of summer. Therefore, depending on the season and time zone, fog may be generated and visibility may be deteriorated, and a road range in which the vehicle speed needs to be lower than the original speed limit may be registered.
In addition, these data can be obtained using the result of having investigated the road surface condition and the road condition for every season and time zone.

The data shown in FIG. 4 is based on the restriction range where congestion of vehicles (traffic buses and other traffic vehicles) and traffic increase due to the time elements including day of the week and time zone due to the presence of the route bus station. Show. For example, as shown in FIG. 4, the “station 1” includes routes 1, 2,... As a road range in which the congestion of vehicles and traffic of people increase beyond a predetermined threshold according to the time zone and day of the week. -Is registered, and each road range is defined in association with road data (road link) of map data. These data can be obtained using the results of road surveys on congestion of vehicles and traffic of people.
In addition to FIGS. 2 to 4, a range that is a road situation in which the traveling state of the vehicle should be limited according to a time element may be registered as the limited range data.

Next, the operation will be described.
FIG. 5 is a diagram showing an outline of driving support in the first embodiment. In FIG. 5, it is assumed that the vehicle is moving from the point A to the point B, the school S1 is in the middle, and the range Z1 including the intersection X3 is registered in the restricted range database 5 as a school route.
First, the arithmetic processing unit 7 uses the vehicle position information acquired by the position detection unit 2 and the travel information (vehicle traveling direction and travel speed) acquired by the acceleration / azimuth detection unit 3 to register the restriction range database 5. It is determined that the vehicle has reached the point A at a predetermined distance or time position up to the limit range Z1.

Next, the arithmetic processing unit 7 refers to the limit range database 5 to determine the road condition of the limit range Z1 in the time element corresponding to the expected time when the vehicle reaches the limit range Z1.
In the example of FIG. 5, the estimated time when the vehicle reaches the limit range Z1 is a school attendance time zone of the school S1 and is not a holiday, and the traffic of students who go to school S1 has a predetermined threshold. Has increased beyond.

Therefore, the arithmetic processing unit 7 refers to the driving action table data in which driving actions to be taken by the vehicle in various road conditions based on the determined road conditions, and determines the driving action corresponding to the driving action table data. In this case, taking into account traveling on the road including the intersection X3 and heading to the point B, a slow speed (for example, about 20 km / h) lower than the speed limit (for example, 40 km / h) of the road including the intersection X3. The driving behavior to drive at speed) is determined.
The arithmetic processing unit 7 converts information indicating the driving action determined with reference to the driving action table data into information in a form that can be output by the display unit 9 or the voice output unit 11.

Next, the arithmetic processing unit 7 outputs driving behavior information in a form that can be output by the display unit 9 or the voice output unit 11 to the display unit 9 or the voice output unit 11 before the vehicle reaches the limit range Z1. .
Thus, the display unit 9 or the voice output unit 11 presents the driving behavior determined by the arithmetic processing unit 7 to the driver by outputting a screen display or voice guidance before the vehicle reaches the limit range Z1. To do.

  The timing at which the driving action determined by the arithmetic processing unit 7 is presented (the time point before the vehicle reaches the limit range Z1) is the driving action determined by the arithmetic processing unit 7 until the vehicle reaches the limit range Z1. Is a timing at which a distance range in which the vehicle can reasonably shift to the traveling state is secured. For example, the vehicle decelerates from 35 km / h → 30 km / h → 25 km / h from the speed limit (40 km / h) of the road including the intersection X3, and decelerates to a slow speed of 20 km / h up to the position immediately before the limit range Z1. By doing in this way, the driver | operator of a vehicle can shift to driving | running | working suitable for the range which should restrict | limit driving | running | working reasonably.

Moreover, although the restriction | limiting range resulting from existence of school S1 was shown, it is the same also about the restriction | limiting range by the road surface condition as shown in FIG. 3, and the restriction | limiting range by the route condition shown in FIG.
For example, while a route bus user gets on and off, the route bus stops, so the following vehicle must also stop. It is also possible to cross the road after a bus user gets on and off. In this case, since the following vehicle cannot pass the route bus, the vehicle travels at a speed lower than the speed limit of the road including the intersection X3.

Further, the arithmetic processing unit 7 determines the road condition in the limited range based on the time element at the time when the vehicle is expected to reach the limited range and the road peripheral information acquired by the information collecting unit 6. The driving action to be taken in the road conditions may be determined.
For example, let us consider a case where a vehicle is traveling on a holiday and the content of the restriction range database 5 is not expected to be a road situation where there are few commuters and the vehicle travel is restricted.
Even in such a case, when the information collection unit 6 obtains the traffic jam information in the limit range Z1 in real time, the arithmetic processing unit 7 has a traffic jam even when the vehicle is expected to reach the limit range Z1. Determine whether to continue.
When it is determined that the traffic jam continues, the arithmetic processing unit 7 refers to the driving behavior table data to determine the driving behavior that the vehicle should take in the traffic jam. For example, a driving action that decelerates can be considered.
The traffic jam information can be obtained from VICS (Vehicle Information and Communication System; registered trademark).

In addition, when event information such as a school festival held on a holiday at the school S1 is acquired by the information collecting unit 6, the arithmetic processing unit 7 determines that this event is the time when the vehicle is expected to reach the limit range Z1. When it is a time zone to be held, it is determined that the restricted range Z1 is a road situation in which the traveling of the vehicle is restricted in the same manner as a traffic situation of people by attending school on weekdays.
Also in this case, the arithmetic processing unit 7 refers to the driving action table data to determine driving action corresponding to the traffic of people exceeding a predetermined threshold. For example, a driving action that decelerates can be considered.

  As described above, the road condition is determined based not only on the registered contents of the limited range database 5 but also on the peripheral information acquired in real time by the information collecting unit 6, and the driving action to be taken in the determined road condition is determined. In this way, it is possible to present to the driver driving behavior that more accurately corresponds to actual road conditions.

In addition, when the destination is set, the arithmetic processing unit 7 searches for a route to the destination that avoids the restricted range or travels within the restricted range or shortens the distance or time, and executes guidance for the route. Also good.
For example, when the point B is set as the destination and the restriction range Z1 is a road situation where the travel of the vehicle should be restricted based on the contents of the restriction range database 5, the arithmetic processing unit 7 is based on the vehicle position and the map database 4. The route from the point A to the point B via the intersection X1, the intersection X2, and the intersection X4 is searched while avoiding the restriction range Z1.
In this case, the expected time to reach point B on the route avoiding the limit range Z1 and the expected time to reach point B from point A via the intersections X3 and X4 (the vehicle is decelerated in the limit range Z1) A route that avoids the limit range Z1 is selected when the time difference between and is within a predetermined threshold range. Thereby, it is not necessary to make an unnecessary roundabout to the point B.

If it is determined by the determination of the time difference that the expected time to reach the point B on the route avoiding the limit range Z1 is late and it takes too much time, the arithmetic processing unit 7 shortens the distance or time for traveling in the limit range. Search for the route to the destination.
For example, if there is a lot of traffic on the road passing through the intersection X3 in the restricted range Z1 and heading to the intersection X4, and the vehicle traveling speed must be reduced to the lowest, turn left at the intersection X3 to the intersection X2 and search for a route toward the point B To do. In this case, a left turn is performed in a state where the vehicle is decelerated to a predetermined speed in the limit range Z1, but the speed of the vehicle can be increased on the road after leaving the limit range Z1, so the expected time to reach the point B is Faster and shorter time (time priority search mode).

In addition, when the search mode that prioritizes minimizing the route distance to the point B is set, the arithmetic processing unit 7 does not avoid the limit range Z1, and passes from the point A via the intersection X3 and the intersection X4. A route toward point B is searched.
In this case, since the vehicle is decelerated in the limit range Z1, it is possible to take the required time from the route from the point A to the point B via the intersection X1, the intersection X2, and the intersection X4 while avoiding the limit range Z1. There is sex.

As described above, according to the first embodiment, the position detector 2 that acquires vehicle position information, the acceleration / orientation detector 3 that acquires travel information indicating the traveling direction and vehicle speed of the vehicle, and the day of the week A limit range database 5 in which a limit range that is a road situation in which the driving state of the vehicle should be limited in accordance with a time element including a season and a time zone is registered in association with map data, vehicle position information, driving information, and Based on the registered contents of the limit range database 5, the arithmetic processing unit 7 that determines the driving action to be taken in the road condition according to the time element at the time when the vehicle is expected to reach the limit range, and the vehicle reaches the limit range The display unit 9 or the voice output unit 11 presenting the driving action determined by the arithmetic processing unit 7 is provided.
In this way, instead of avoiding the limit range uniformly as in the past, driving support is provided so as to pass the limit range by giving a predetermined travel limit, so when the limit range overlaps by time zone Even if it exists, the driving | running | working suitable for the range which should carry out driving | running | working restriction | limiting can be performed, without making an unnecessary detour.

Moreover, according to this Embodiment 1, it has the information collection part 6 which acquires the periphery information of the road where a vehicle drive | works, and the time element in the time when the arithmetic processing part 7 is estimated that a vehicle reaches | attains a restriction | limiting range. Based on the road peripheral information acquired by the information collecting unit 6, the road condition in the restricted range is determined, and the driving action to be taken in the determined road condition is determined.
By configuring in this way, it is possible to present to the driver driving behavior that more accurately corresponds to actual road conditions.

  Further, according to the first embodiment, the road condition in the restricted range is a road condition defined by at least one of a vehicle congestion situation, a pedestrian traffic situation, and a road surface condition. By doing in this way, it can respond to the road condition of various factors which restrict | limit driving | running | working of a vehicle.

  Further, according to the first embodiment, when the destination is set, the arithmetic processing unit 7 searches for a route to the destination that avoids the limit range or travels the limit range or shortens the distance or time. The route is guided. By doing in this way, the driver | operator of a vehicle can guide the path | route which goes to the destination, without making an unnecessary detour.
