DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle external information notifying device for notifying a passenger of information sent from the outside of a vehicle using a device provided inside the vehicle, and a function of notifying the external information. The present invention relates to a vehicle route guidance device that guides a vehicle along a route to a preset destination.

[0002]

2. Description of the Related Art In recent years, the position of a vehicle has been measured by receiving radio waves from artificial satellites, and the position has been collated with map information mounted on the vehicle. A so-called GPS navigation system that displays a vehicle position and notifies the driver of the position is provided for general demand.

In this system, the map information stored in advance in a device mounted on the host vehicle is information at the time of storage, not information at the time of actual display. In this system, the information at the actual time is only the position of the host vehicle. Therefore, passengers have to rely on an external display such as a traffic congestion display signboard on the Metropolitan Expressway for information that changes every moment, such as road regulation or traffic congestion information due to an accident. In addition, there are cases where map information mounted on a vehicle does not match the actual one due to road repair work or the like.

On the other hand, a system has been developed in which information is transmitted from a base station or a beacon installed on the side of a road, the information is received by a receiving device of a vehicle, and the passenger is notified. For example, a system has been developed that transmits traffic congestion information, regulation information, accident information, and the like of the entire Metropolitan Expressway from a base station on a metropolitan expressway in a city center and displays the information on a display device mounted on a vehicle. A display such as a traffic congestion information display plate currently installed in more than a dozen locations on the Metropolitan Expressway can be displayed on a display device in the vehicle. According to this, there is no case where the contents cannot be sufficiently checked by passing through the conventional display board installed above or on the side of the road, and the information can be checked when the passenger desires.

When information is transmitted by radio waves or light from a beacon installed on the side of the road, passengers can transmit more information by transmitting important information within a range where the radio waves and the like can reach. Information can be obtained. For example, if information on an approaching intersection is displayed, the content can be confirmed even after passing through a conventional road display board, similarly to the above-described traffic congestion information. Further, it is possible to provide more useful information to the passenger by, for example, creating and displaying information on the time required to reach a predetermined point based on the current road conditions.

[0006] As described above, the current information is notified, so that the passenger can make a route selection or the like corresponding to this situation.

Japanese Patent Application Laid-Open No. 62-95423 discloses an example of such a device for notifying a passenger in a vehicle of external information.
There is an apparatus described in Japanese Unexamined Patent Application Publication No. H10-26095. This device sequentially displays a route that avoids a congested section when there is a congested section ahead of the own vehicle in the traveling direction of the route searched in advance.

[0008]

However, according to the prior art, when there is a detour that can avoid a congested road, this can be notified and the passenger can be provided with information. If there is no detour and there is no choice but to enter the congested section, there is a problem that no information can be provided to the passenger. For example, on a road that cannot be easily exited once it enters, such as an expressway, it is not possible to select a detour without an interchange in front of the congested section. We cannot provide information to avoid.

[0009] In addition, since only a detour is shown as a method of avoiding congestion, there is a problem that no information can be obtained on a method of resting somewhere and waiting until the congestion is resolved.

Further, even when a detour is shown, a route that is completely different from the route already set may be shown, and there is a problem that the passenger is confused. The present invention has been made in order to solve the above problems, and provides a vehicle in which a passenger can take appropriate measures according to the situation by providing appropriate information on traffic congestion and traffic regulation sections. It is an object to provide an external information notification device for vehicles or a route guidance device for vehicles.

[0011]

In order to achieve the above object, an external information notification device for a vehicle according to the present invention includes a traffic jam or a traffic regulation section to avoid the traffic jam. A faulty section detecting means for detecting a faulty section which is a section without a detour; a running section detecting means for determining whether or not the own vehicle is traveling in the faulty section; An information selection unit that selects information related to traffic congestion or traffic regulation included in the obstacle section from the external information received when it is determined that the vehicle is traveling; and a notification that notifies the passenger of the information selected by the information selection unit. Means.

In the apparatus according to the second aspect of the present invention, the information selecting means selects at least one of a remaining traffic jam length and a remaining traffic jam passing required time, and the notifying means notifies them.

[0013] In the apparatus according to the third aspect of the present invention, the information selecting means selects the cause of the traffic congestion or the regulation, and the notifying means notifies them.

According to a fourth aspect of the present invention, the information selecting means selects information for evacuating from the traffic congestion, and the notifying means notifies the information.

According to a fifth aspect of the present invention, the information for evacuating from the traffic congestion includes at least one of information on a rest facility and a congestion elimination predicted time, and these are reported by the reporting means. is there.

According to a sixth aspect of the present invention, the information selecting means selects information on traffic regulation requiring emergency evacuation, and the notifying means notifies the information.

Further, according to a seventh aspect of the present invention, there is provided the vehicle route guidance apparatus, wherein the traffic congestion / regulation section detecting means for detecting a congestion or a traffic regulation section in front of the route based on the external information; Information on rest facilities to avoid traffic jams or restricted traffic sections and traffic jams or traffic
There is provided an information selecting means for selecting both the regulation elimination predicted time from the external information, and a notifying means for notifying a passenger of the information selected by the information selecting means.

[0018]

[0019]

The present invention has the above-described configuration, and notifies appropriate information on traffic congestion and traffic regulation by informing.
It is possible to encourage the user to respond to the traffic congestion or the like according to the situation.

For example, in the device according to the first aspect of the present invention, in a section where there is no detour to avoid traffic congestion, etc., the passenger can provide such information by providing the information regarding the traffic congestion. It can respond to traffic congestion and the like.

In the apparatus according to the second aspect of the present invention, the remaining traffic jam length or the remaining traffic passage time is reported, so that the passenger can know in advance the time required for passing the traffic jam. .

In the apparatus according to the third aspect of the present invention, the cause of the traffic jam or the like is notified, so that the occupant can judge the degree of the traffic jam or the like from the cause. Further, in the apparatus according to the fourth aspect of the present invention, information for avoiding traffic congestion is notified, so that the passenger can escape from the traffic congestion based on this information. Further, in the device according to the fifth aspect of the present invention, since information on rest facilities and predicted congestion elimination time can be reported as information for avoiding congestion,
Passengers can take measures to avoid congestion, such as resting at rest facilities until the congestion is resolved.

Further, in the device according to the invention described in claim 6, information relating to traffic regulation requiring emergency evacuation is notified, so that the passenger can evacuate appropriately.

Furthermore, in the apparatus according to the present invention, since a resting facility and a predicted time at which traffic congestion will be resolved are notified, a method for avoiding traffic congestion other than a method of taking a detour is provided. In addition, a method of resting at a rest facility until the traffic jam is resolved can be adopted.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments according to the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a vehicle external information notification device according to this embodiment. GPS antenna 10 and GPS receiver 1 that constitute a GPS navigation system
2, various sensors such as a vehicle speed sensor 14, a steering sensor 16, a geomagnetic sensor 18, and a distance sensor 20, and a control unit 22. G in the GPS receiver 12
The radio wave received from the geodesic satellite in the satellite orbit received by the PS antenna 10 is received. The control unit 22 calculates the latitude and longitude of the current position of the vehicle based on the direction of the received radio wave.
Other sensors (vehicle speed sensor 14, steering sensor 16, geomagnetic sensor 18, distance sensor 20) are provided to assist in calculating the position of the host vehicle when radio waves from satellites cannot be received. For example, the vehicle speed is detected by the vehicle speed sensor 14 to calculate how much the vehicle has moved during a predetermined time. This distance can also be calculated by the distance sensor 20. The steering sensor 16 and the geomagnetic sensor 18 can calculate how much the own vehicle has changed the traveling direction. The detection of the amount of change in the traveling direction may be performed by a gyro system. Then, the latitude and longitude detected by these sensors are compared with the map information stored in the map information storage unit 24, and the position of the own vehicle on the map is calculated by the control unit 22. Then, the map information and the position of the host vehicle are superimposed and displayed on the display unit 26 provided near the driver's seat to notify the passenger. Further, the detected position of the host vehicle is always compared with the map information, and it is determined whether the position on the map is an appropriate position. For example, if there is no road at the place where the vehicle is currently traveling and there is a road in parallel with the traveling locus of the vehicle, the vehicle position is shifted and the current position is corrected to be on the road. The position detection accuracy of the GPS or the like is compensated by such correction.

Further, in the present apparatus, a destination point is set in advance, and a route to the destination point is stored, thereby guiding a route to be selected in front of an intersection to be turned or the like. Guidance can be provided along the route. When the destination is input from the input unit 28, the control unit 22 searches for a route from the current location measured by the GPS to the destination, and the searched route is stored in the route storage unit 30. Then, the route guidance is performed by comparing the route stored during the actual traveling with the position of the own vehicle. The route guidance is performed, for example, in front of an intersection where a right or left turn is made, by displaying a map around the intersection with the display unit 26 to indicate the route with an arrow or the like. . Further, in the case of this device, in addition to the display, guidance by voice is also performed by the voice generation unit 32. For example, when approaching an intersection to make a right turn, a voice message such as "The next intersection is a right turn." If the notification is made by voice, the driver can select the set route without looking at the display on the display unit 26, so that the driver does not need to turn his / her line of sight from the front.

The functions described above are implemented in the map information storage unit 24.
The operation is performed based on the information stored by the computer, and the information at the present time is not taken into account. That is, the searched route may not be able to actually pass due to traffic regulations such as road construction. In addition, there is a section where traffic is congested in a part of the searched route, and there may be a case where actually selecting another route reaches the destination in a short time. Such inconvenience is caused by the fact that the current information is only the position of the vehicle and does not take into account the current traffic conditions of the road such as traffic jams and regulations.

In the present apparatus, such information at the present time is received from the outside by a method described later, and is used as a determination factor for route selection and the like. As a method of transmitting the current traffic situation and the like from the outside to each vehicle, a method by FM multiplex broadcasting, a method of transmitting a radio wave or light from a beacon provided on the side of a road, and the like are in practical use.

The present apparatus includes an FM multiplex receiver 34 for receiving the above-described FM multiplex broadcast and a beacon receiver 36 for receiving radio waves from a beacon as receiving means for external information.
It has.

The FM multiplex receiver 34 includes an FM antenna 38
Receive the FM wave received by the. The information on the FM multiplex is, for example, traffic congestion on roads and regulation information. In addition, the beacon receiver 36 receives and receives a radio wave from a beacon provided on the side of the road by the beacon antenna 40. Beacons are suitable for transmitting information over a relatively small area. By utilizing this, a beacon transmission source is installed at a predetermined position before a specific intersection, and information unique to this intersection is transmitted. Intersection-specific information
For example, it is a destination display for each branching direction of an intersection conventionally displayed as a signboard in front of the intersection, and a required time (travel time) from the corresponding intersection to the displayed destination. On the other hand, the aforementioned FM multiplex wave is suitable for transmitting information over a wide area, and information is transmitted from a base station. The information content includes, for example, traffic congestion information on the entire Metropolitan Expressway, regulation information on accidents and falling objects, and other messages from the road manager. Of course, it is also possible to transmit congestion information, regulation information, and the like transmitted by the FM multiplex wave using a beacon.

As described above, the information received by the FM multiplex receiver 34 or the beacon receiver 36 is temporarily stored,
It is displayed on the display unit 26 after the display instruction is given. This display instruction is given, for example, after the reception is completed or after it is detected that the vehicle has passed just below the beacon transmission source. Further, it may be after a predetermined distance has elapsed from the reception or after a predetermined time has elapsed. Further, it is also preferable that the display is made by a passenger giving an instruction from the input unit 28. In such a case, the display is performed only when the passenger requests it, so that the external information can be prevented from being interrupted when the passenger is looking at another screen.

As described above, in the present apparatus, map information around the position of the host vehicle based on GPS or the like, external information received by a beacon or an FM multiplex wave, and the like are displayed on the display unit 26 and provided to the passenger. It is necessary to inform. Such information includes a variety of information. In particular, the external information includes a wide variety of information such as information on the fullness / vacancy of a parking lot and information on a parking area, in addition to the above-mentioned information such as traffic jam and regulation. In order to display these various kinds of information, the display unit 26 requires a considerably large screen. However, the display unit 26 needs to be provided in the instrument panel of the vehicle. Can not do. Further, even if a large amount of information can be displayed at once, the passenger must read necessary information from among them.

Therefore, it is important to notify the occupant of appropriate information according to the situation from among the various kinds of information described above. The present device provides information corresponding to the traffic jam or the regulation section to the passenger when the section is detected.

When information such as traffic congestion is received as external information, a trouble section including the traffic congestion is detected by a trouble section detection unit 42 included in the control unit 22. The obstacle section referred to here is a section in which there is no branch point or intersection and no detour can be selected from the current position of the vehicle to the section where traffic is congested or restricted. For example, between interchanges next to a highway. In this case, even if the entire section is not congested and only the exit of the next interchange is congested, if the vehicle continues to travel, traffic will inevitably be entered. Therefore, the entire section is detected as a troubled section.

Then, the traveling section detecting means 44
The current position of the own vehicle measured by the PS or the like is compared with the above-described obstacle section to determine whether the own vehicle is traveling in the obstacle section. That is, it is detected whether the traveling section of the own vehicle is a failure section. When it is determined that the own vehicle is traveling in the obstacle section, the information selecting unit 46 selects information on the corresponding traffic jam or regulation from the external information by FM or beacon. Then, this information is displayed on the display unit 26 to notify the passenger.

FIG. 2 shows a display example of information related to traffic congestion and the like. FIG. 2 shows a display example in which the display unit 26 is traveling on the highway 100. The current position of the host vehicle is indicated by a dashed circle 102 near the center of the screen, and the traveling direction is indicated by a wedge-shaped arrow 104. The traveling positions of the own vehicle are interchange (IC) 106 and □□ I. C. 108
Between. A traffic congestion section of about 5 km is indicated by a thick solid line 110 in front of the interchange 108 ahead.
In addition, in front of the own vehicle, the OO service area (S.
A. ) 112.

In the case shown in FIG. 2, the own vehicle does not have an interchange or a junction just before the congested section, and therefore cannot select a detour. In other words, in this case, the area between the two interchanges 106 and 108 is the above-described obstacle section. Therefore, the vehicle is in the congested section 110
Is not traveling, but the traveling section detector 44 determines that the vehicle is traveling in the obstacle section. Then, as described above, there is no road that bypasses the congested section, and only the information related to the congested traffic is displayed on the character information display section 114. FIG.
Indicates that there is a congestion section ahead, the remaining length of this congestion section, and the time required to pass through the congestion section (time required for passage). In FIG. 2, the remaining length of the congestion section indicates the total length of the congestion because the section has not yet entered the congestion section. If you have already entered a congested section,
The distance between the start point of the traffic jam and the position of the host vehicle is calculated, and this is displayed as the remaining traffic jam length. The transit time is
This is calculated from the degree of congestion and the remaining length of the congestion. The passenger can determine from this information how much he / she can get through the congestion, and the degree of irritation is lighter than when he / she is not informed of this information at all.

FIG. 3 shows a case where information relating to the cause of traffic congestion or regulation is displayed on the character information display section 114. The same reference numerals as in FIG. 2 denote the same parts, and a description thereof will be omitted. In addition to “congestion due to accident” in FIG. 3, there are indications such as “lane regulation by construction” and “speed regulation by rain”.
It is also preferable to display "accident congestion remaining 5 km 30 minutes" or the like in addition to the display of the traffic congestion length and the time required for passage in FIG.

FIG. 4 shows a case where information for evacuating traffic congestion is displayed on character information display section 114. In the case of FIG. 4, since the own vehicle is already traveling in the obstacle section, there is no detour to avoid the congestion section ahead. However, it is also possible to take a break until the traffic congestion is resolved in the service area 112 ahead to avoid the traffic congestion. In this state, the distance to the service area and the estimated time to eliminate the traffic jam are displayed to assist in determining whether to continue running or to take a break.

FIG. 5 shows a case where an emergency evacuation is required due to some trouble in the tunnel. The space between the tunnel entrance symbols 116 is indicated by a thick solid line as a restricted section 118. This indicates a regulation prohibiting entry into the tunnel in the event of an accident or fire in the tunnel. However, vehicles already in the tunnel must be provided with information about evacuation to inform them that they need to escape from the tunnel promptly. For this purpose, the evacuation to the rear is displayed on the character information display unit 114. In a tunnel, it is important to know whether the evacuation route is closer to the evacuation route before or after.
In addition, it is necessary to take evacuation guidance in consideration of the location where the accident occurred. In the case shown in FIG. 5, since the vehicle enters the tunnel slightly, the message "Get off from the car and evacuate to the rear" is displayed to guide the passenger to the rear exit. If an accident or the like occurs behind the vehicle, a message such as "Please drive as it is" is displayed, and the driver is guided to exit the tunnel from the front exit. It is also preferable that such information regarding emergency evacuation is provided during passage through a bridge in addition to a tunnel.

Further, when the vehicle reaches the last part of the traffic congestion or when the vehicle enters the restricted section, a display for urging the lighting of the hazard lamp is displayed on the display unit 26. For example, the map display is deleted and a red triangle mark is displayed. In this way, even when the vehicle reaches the end of the traffic congestion and the speed drops sharply, the lighting of the hazard lamp can be urged and the attention of the vehicle behind can be urged. At this time, when the display screen is configured by a touch panel, it is more preferable that the hazard lamp blinks even if any part of the screen is touched. In this case, even for an unfamiliar vehicle, there is no need to find a switch for turning on the hazard lamp.

Further, when approaching the head of the traffic congestion while traveling in the traffic congestion section, it is also preferable to notify the occupant that the vehicle is about to exit the traffic congestion section soon. Thus, even if the traffic congestion is resolved and the speed increases, the passenger can prepare in advance.

FIG. 6 is a flowchart showing the display of the information related to the congestion and the regulation described above. When the external information is received (S200), it is determined whether there is a fault section in the information (S202). When a faulty section is detected, it is determined whether the vehicle is currently traveling in the faulty section (S204). If the vehicle is traveling in the obstacle section, it is further determined whether the obstacle is a regulation that requires emergency evacuation (S
206). If emergency evacuation is necessary, it is determined whether the vehicle is traveling in this restricted section (S210).
For example, evacuation information as shown in FIG. 5 is displayed (S21
0), a display for prompting the lighting of the hazard lamp is performed (S211). Also, if you are not driving in a restricted section,
Regulation information such as "accident in tunnel, entry prohibited" is displayed (S212). In step S206, if the received information related to traffic congestion / regulation does not relate to emergency evacuation, it is determined whether there is a rest facility within the obstacle section (S
214). If there is a rest area such as a service area, Figure 4
The information about the rest facility as shown in is displayed. If there is no rest facility, it is determined whether the information of the traffic jam length and the time required for passing is received (S218). If this information has been received, a display as shown in FIG. 2 is made and the degree of traffic congestion is notified to the passenger (S220). If there is no information such as the length of the traffic jam, it is determined whether information on the cause of the traffic jam or the like has been received (S222).
Is displayed (S224).

When the above conditions are not satisfied, only the information display on the map is performed and the character information display section 114
Is not notified to the passengers. If it is determined in step S204 that the vehicle is not traveling in the obstacle section, a search for a detour, for example, as in the above-described conventional device, is started automatically or in response to a passenger's instruction (S226).

FIG. 7 shows another embodiment according to the present invention. The same components as those of the apparatus shown in FIG. 1 are denoted by the same reference numerals, and description thereof will be omitted. In this embodiment, a component different from the above-described embodiment is a control unit 50.

When external information is received by the beacon receiver 36 or the FM multiplex receiver 34, the traffic congestion / regulation section detecting section 52 determines whether or not information relating to traffic congestion has been received. Part 3
It is determined whether or not it is on the route stored in 0. When there is traffic congestion on the route, the information selecting unit 54 first selects information on the resting facility and a predicted congestion elimination time from external information, and displays them on the display unit 26. For example, "XX drive-in 2 km" is displayed.

When the passenger instructs a re-search for a route from the input unit 28, the waypoint setting unit 56 sets the head of the detected congestion / regulation section as a waypoint. Then, the route search unit searches for a route (a detour) to the set waypoint.

FIG. 8 shows an example of the search result. The own vehicle 102 moves toward an intersection 120 on a road 122 at the center of the screen.
Along the way. This road is congested up to the intersection 120, which is indicated by the congestion display symbol 124. There are roads 126 and 128 running parallel to this road, and a traffic jam display 124 is also displayed on these roads. When the passenger instructs a re-search, a route to the head of the congestion on the route (in this case, the intersection 120) is searched, and the required time of each route is displayed. In the figure, the required time display 132 is shown for three routes: a route that turns left at the intersection 130 and detours along the arrow A, a route that turns left at the intersection 130 and detours along the arrow B, and an original route. Has been made. In the case of FIG.
It can be seen that the required time of the original route is the shortest, so that the required time is not shortened even when passing through another route.

FIG. 9 is a flowchart for searching for a detour in the present embodiment. When information related to traffic congestion or regulation is received from the outside by the beacon receiver 36, the FM multiplex receiver 34, or the like, it is determined whether the traffic congestion or the like is on a route searched in advance (S230). If there is a congested section on the route, the system waits for a passenger search instruction from the input unit 28 (S232). Then, the start point of this traffic jam is determined (S234). A search for a detour to the leading point is performed, and it is determined whether a detour route exists (S236). If there is a detour, the required time of each of the searched detour and a preset route is displayed. The passenger can determine which route to select by looking at the display of the required time. If there is no detour, a message such as "there is no detour" is displayed (S240).

FIG. 9 shows a case where a route has been set in advance. However, if a route has not been set, it is determined whether the own vehicle is traveling in a congested section or the like to search for a detour. It is also preferable to determine the start.
Therefore, in this case, it can be understood that a step of determining whether the own vehicle is traveling in a congested section or the like may be provided before step S230 in the flowchart of FIG.

It is also preferable to display only the route of the shortest required time among the re-searched routes.

As described above, the apparatus according to the present embodiment notifies the passenger of two methods: a method of avoiding traffic congestion by taking a detour, and a method of taking a break to wait for elimination of traffic congestion and avoiding traffic congestion. Can be. For passengers, being notified of a plurality of methods provides a wider range of choices.

Although the information on the resting facilities is received as information from the outside, it is also preferable to use the facility information stored in the map information storage unit 24.

In addition, when the detour is searched for, the head of the traffic congestion / restricted section to be searched is set as the waypoint, so that it is possible to return to the initially searched route at an early point in time. Therefore, the passenger can travel on the new route with the minimum information, and the burden is reduced.

As described above, the apparatus according to the present embodiment can display appropriate information based on the content of the obtained external information, and the occupant does not have to search for necessary information. Therefore, the passenger can concentrate on the driving operation without performing a troublesome search operation.

The above embodiments all describe the case where the current position is measured by GPS or the like.
It is also possible to measure the current position by using a beacon.
That is, if a code specifying the source of the beacon is included in the information from the beacon, the position of the own vehicle can be specified by the code of the beacon. Therefore, it is understood that a device that detects the current position of the own vehicle using the code of the beacon is also included in the scope of the present invention, excluding the components related to the navigation system using the GPS and the like in the above-described embodiments.

[0059]

As described above, according to the present invention, it is possible to surely notify the passenger of the information regarding the target traffic jam or traffic regulation.

In particular, according to the first aspect of the present invention, even in a section where there is no detour, information about the traffic congestion is provided so that the passenger can respond to the traffic congestion based on the information. Can be.

According to the second aspect of the present invention, the occupant can know in advance the time required for passing through traffic,
It is possible to reduce annoyance without knowing how long the traffic will continue.

Further, according to the third aspect of the present invention, the occupant can judge the degree of congestion from the cause, and can estimate the time to resolve the congestion.

According to the fourth aspect of the present invention, the occupant can escape from the traffic jam based on information for avoiding the traffic jam.

According to the fifth aspect of the present invention, the occupant can take a break at the notified resting facility and wait for the elimination of the traffic jam. In addition, it is possible to determine how long a break should be taken based on the notified traffic jam elimination predicted time.

According to the invention described in claim 6, information on traffic regulation requiring emergency evacuation is notified, so that the passenger can perform an appropriate evacuation.

Further, according to the invention described in claim 7,
Since the rest facility and the predicted time to eliminate the traffic jam are notified, as a method of avoiding the traffic jam other than the method of taking the detour, a method of resting at the rest facility until the traffic jam is resolved can be adopted.
