Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a vehicle external information informing device for informing passengers of information sent from the outside of the vehicle by means of a device provided inside the vehicle, and a function of informing 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, radio waves from artificial satellites are received to measure the position of a vehicle, and this position is compared with map information mounted on the vehicle to determine a map around the vehicle and a map on this map. A so-called GPS navigation system, which displays the vehicle position and informs the driver, is in general demand.

In this system, the map information stored in advance in the device mounted on the vehicle is the information at the time of storage, not the information at the time of actual display. In this system, the information at the actual time is only the position of the own vehicle. Therefore, for information that changes moment by moment such as road regulations and traffic congestion information due to accidents, the passengers had to rely on external displays such as traffic congestion display signs on the Shuto Expressway. In addition, the map information mounted on the vehicle may not match the actual situation 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 vehicle receiver, and the information is notified to passengers. For example, on the Metropolitan Expressway in central Tokyo, etc., a system has been developed that transmits congestion information, regulation information, accident information, etc. of the entire Metropolitan Expressway from a base station and displays this on a display device mounted on the vehicle, It is possible to display a display such as a traffic jam information display board, which is currently installed at more than ten places on the Shuto Expressway, on the display device in the vehicle. According to this, the case where the contents cannot be sufficiently confirmed by passing through the conventional display plates installed on the upper side or the side of the road is eliminated, and the information can be confirmed when the passenger desires.

Further, when transmitting information by radio waves or light from beacons installed on the side of the road, the passengers can get more detailed by transmitting particularly important information within the reach of the radio waves. Information can be obtained. For example, if the information of the approaching intersection is displayed, the contents can be confirmed even if the information has passed through the conventional road display board, like the above-mentioned traffic congestion information. Furthermore, it is possible to provide more useful information to the passenger by creating and displaying information about the time required to reach a predetermined point based on the current road conditions.

As described above, the passengers can make a route selection or the like corresponding to this situation by being notified of the current information.

As an example of such an apparatus for informing passengers in the vehicle of information from the outside, Japanese Patent Laid-Open No. 62-95423.
There is a device described in the publication. This device sequentially displays the routes that avoid the congested section when there is a congested section ahead of the traveling direction of the vehicle on the previously searched route.

[0008]

However, according to the prior art, when there is a detour that can avoid a congested road, it is possible to inform this and provide the passengers with information. If there is no detour and there is no choice but to enter the traffic jam section as it is, there is a problem that it is impossible to provide any information to the passengers. For example, on a road that is hard to get out once you enter, such as an expressway, you cannot choose a detour even if there is a congested section in front of you and there is no interchange in front of it. We cannot provide information to avoid.

Further, since a detour is only shown as a method for avoiding traffic congestion, there is a problem in that no information can be obtained on a method of, for example, taking a break somewhere and waiting until the traffic congestion is resolved.

Further, even when the detour is shown, a route which is completely different from the route already set may be shown, and there is a problem that passengers are confused. The present invention has been made to solve the above problems, and a vehicle that allows passengers to take appropriate measures according to the situation by providing appropriate information regarding traffic congestion and traffic regulation sections.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of the vehicle external information notifying apparatus of this embodiment. GPS antenna 10 and GPS receiver 1 constituting the 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
Radio waves from the geodetic satellite on the satellite orbit received by the PS antenna 10 are received. Based on the direction of this received radio wave, the control unit 22 calculates the latitude / longitude of the current position of the vehicle.
Other sensors (vehicle speed sensor 14, steering sensor 16, geomagnetic sensor 18, distance sensor 20) are provided to supplementarily calculate the position of the vehicle when radio waves from the satellite cannot be received. For example, by detecting the vehicle speed with the vehicle speed sensor 14, how much the own vehicle has moved in a predetermined time is calculated. This distance can also be calculated by the distance sensor 20. Further, the steering sensor 16 and the geomagnetic sensor 18 can be used to calculate how much the vehicle has changed its traveling direction. The amount of change in the traveling direction may be detected 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 host vehicle on the map is calculated by the control unit 22. Then, the map information and the position of the own vehicle are displayed in an overlapping manner on the display unit 26 provided near the driver's seat to notify the passenger. Further, the detected position of the own vehicle and the map information are constantly compared to determine whether the position on the map is a proper position. For example, when there is no road at the place where the vehicle is currently traveling and there is a road parallel to the traveling locus of the vehicle, the position of the vehicle is shifted and the current position is corrected so as to be on the road. The position detection accuracy of GPS or the like is compensated by such correction.

Further, in this apparatus, a destination point is set in advance and a route to reach this destination point is stored, so that a route to be selected before an intersection to be turned or the like is guided and stored. Guidance can be made along the route. When the destination point is input from the input unit 28, the control unit 22 searches for a route from the current position measured by the GPS to the destination point, 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 host vehicle. The route guidance is performed, for example, in front of an intersection that makes a right turn or a left turn, by displaying the map around the intersection and displaying the route with an arrow or the like, and when entering an expressway, etc. is displayed. . Further, in the case of the present apparatus, in addition to the display, the voice generation unit 32 also performs voice guidance. For example, when approaching an intersection where a right turn is to be made, a voice message such as "Turn right at the next intersection." If the notification is given by voice, the driver can select the set route without looking at the display of the display unit 26, so that the line of sight is not warped from the front.

The functions described above are available in the map information storage unit 24.
It operates based on the information stored by, and the current information is not taken into consideration. That is, the searched route may actually be blocked due to traffic restrictions such as road construction. In addition, there may be a case where a part of the searched route is congested, and actually selecting another route may reach the destination point in a short time. Such inconvenience is caused by the fact that the current information is only the position of the own vehicle and traffic conditions on the road such as traffic congestion and regulations are not taken into consideration.

In the present apparatus, such information at the present time is received from the outside by a method described later and used as a judgment factor such as route selection. As a method of transmitting the current traffic condition or the like from the outside to each vehicle, currently, a method using FM multiplex broadcasting, a method of transmitting radio waves or light from a beacon provided on the side of the road, and the like are practically available.

The present apparatus uses an FM multiplex receiver 34 for receiving the above-mentioned FM multiplex broadcast as a means for receiving external information and a beacon receiver 36 for receiving radio waves from a beacon.
Is equipped with.

The FM multiplex receiver 34 has an FM antenna 38.
The FM wave received by is received. The FM multiplex information is, for example, road congestion status or regulation information. Further, the beacon receiver 36 receives and receives radio waves from a beacon provided on the side of the road by the beacon antenna 40. Beacons are relatively narrow range, suitable for transmitting information. Utilizing this, a beacon source is installed at a predetermined position before a specific intersection and information unique to this intersection is transmitted. What is information unique to intersections?
For example, the display of destinations according to the branching direction of the intersection, which is conventionally displayed as a signboard in front of the intersection, and the required time (travel time) from the corresponding intersection to the destination displayed above are displayed. On the other hand, the above-mentioned FM multiplex wave is suitable for transmitting information in a wide area, and information is transmitted from the base station. This information content is, for example, traffic congestion information on the entire Metropolitan Expressway, regulation information due to accidents, falling objects, etc., and other messages from the road administrator. Of course, it is also possible to transmit the traffic congestion information and the regulation information transmitted by the FM multiplex by the beacon.

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

As described above, in the present apparatus, the map information around the position of the vehicle based on GPS or the like and the external information received by the beacon or the FM multiplex wave are displayed on the display unit 26 and displayed to the passenger. I need to inform you. These pieces of information include various kinds of information, and in particular, external information includes various kinds of information such as the above-mentioned traffic jams and regulations, information about full and empty parking lots, information about parking areas, and the like. The display unit 26 is required to have a considerably large screen in order to display these various kinds of information, but it is necessary to provide the display unit 26 in the instrument panel of the vehicle, and to provide such a large screen due to space limitation. I can't. In addition, even if a large amount of information can be displayed at one time, the passenger must read the necessary information from the passengers.

Therefore, it is important to notify the passenger of appropriate information according to the situation from among the various kinds of information described above. When a traffic jam or a restricted section is detected, this device provides the passenger with information corresponding to the detected section.

When information such as traffic jam is received as the external information, a troubled section including the traffic jam is detected by the troubled section detecting unit 42 included in the control unit 22. The obstacle section here is a section from the current position of the own vehicle to the section where traffic is congested or regulated, and there are no branch points or intersections and a detour cannot be selected. For example, between interchanges next to a highway. In this case, even if this entire section is not a traffic jam and only the vicinity of the exit of the next interchange is a traffic jam, the traffic will inevitably become a traffic jam if the vehicle continues to run, so the entire section is detected as a faulty section.

Then, by the traveling section detecting means 44, G
The present position of the host vehicle measured by PS or the like is compared with the above-mentioned 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 host vehicle is the obstacle section. When it is determined that the host vehicle is traveling in the obstacle section, the information selection unit 46 selects the relevant information regarding traffic congestion or regulation from the external information by the FM or the beacon. Then, this information is displayed on the display unit 26 to notify the passenger.

FIG. 2 shows a display example of information regarding traffic congestion. FIG. 2 shows a display example when 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 arrow 104. The traveling positions of the host vehicle are ΔΔ interchange (IC) 106 and □□ I. C. 108
Is in between. In front of the interchange 108 in front, a thick solid line 110 indicates a traffic jam section of about 5 km.
In front of the host vehicle, a service area (S.
A. ) 112.

In the case of FIG. 2, since the own vehicle has no interchange or junction in front of the congested section, the detour cannot be selected. That is, in this case, the area between the two interchanges 106 and 108 is the above-mentioned obstacle section. Therefore, your vehicle is in the traffic jam section 110
Although the vehicle is not traveling, the traveling section detection unit 44 determines that the vehicle is traveling in the obstacle section. Then, as described above, there is no road that bypasses this traffic congestion section, and only the information regarding this traffic congestion is displayed on the text information display unit 114. Figure 2
In, there is displayed a traffic jam section ahead, the remaining length of this traffic jam section, and the time required to pass through the traffic jam section (passing time). In FIG. 2, the remaining length of the traffic jam section indicates the total length of the traffic jam because the traffic jam section is not yet entered. If you have already entered the traffic jam section,
The distance between the traffic congestion start point and the vehicle position is calculated, and this is displayed as the traffic congestion remaining length. Also, the transit time is
This is calculated from the degree of congestion and the remaining length of the congestion. The passengers can judge from such information how much to clear the traffic jam, etc., and the degree of frustration is lighter than that in the case where such information is not known at all.

FIG. 3 shows a case where information relating to the cause of congestion or regulation is displayed on the character information display portion 114. The same symbols as those in FIG. 2 are given to the same displays, and the description thereof is omitted. In addition to “Traffic due to accident” in FIG. 3, there are indications such as “lane regulation due to construction” and “speed regulation due to rain”.
It is also preferable to display "accident congestion remaining 5 km 30 minutes" together with the display of the congestion length / passing time in FIG.

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

FIG. 5 shows the case where some kind of obstacle occurs in the tunnel and an emergency evacuation is required. A space between the entrance and exit symbols 116 of the tunnel is displayed as a thick section with a restricted section 118. This shows regulations that prohibit entry into the tunnel if there is an accident or fire in the tunnel. However, for vehicles already in the tunnel, information about evacuation must be provided to notify that it is necessary to quickly exit the tunnel. For this reason, the text information display unit 114 displays that evacuation is to the rear. In the tunnel, it is important to know whether the evacuation route is closer to the front or back.
In addition, it is necessary to guide the evacuation in consideration of the location where the accident occurred. In the case shown in FIG. 5, since it is slightly entering the tunnel, the message “get out of the car and evacuate to the rear” is displayed so as to guide the passenger to the exit at the rear. If an accident or the like occurs behind your vehicle, the message “Please continue driving.” Will be displayed and you will be asked to exit the tunnel from the front exit. It is also preferable to provide such information regarding emergency evacuation while the bridge is passing, in addition to the tunnel.

Further, when the last part of the traffic jam is reached or a restricted section is entered, a display for prompting lighting of the hazard lamp is displayed on the display section 26. For example, the map display is deleted and a red triangle mark is displayed. In this way, even when the last part of the traffic jam is reached and the speed is drastically reduced, the hazard lamps can be lit and the attention of the rear vehicle can be urged. At this time, if the display screen is composed of a touch panel, it is more preferable that the hazard lamp blinks even if any part of the screen is touched. In this case, it is not necessary to search for a switch for turning on the hazard lamp even for an unfamiliar vehicle.

Further, it is also preferable to inform the passenger that he / she is about to leave the traffic jam section when he / she approaches the beginning of the traffic jam while traveling in the traffic jam section. As a result, the passenger can prepare in advance even if the congestion is resolved and the speed is increased.

FIG. 6 shows a flow chart relating to the display of the information regarding the traffic congestion and the regulations described above. When the external information is received (S200), it is determined whether there is a faulty section in the information (S202). When the obstacle section is detected, it is determined whether the vehicle is currently traveling in the obstacle section (S204). If the vehicle is traveling in the obstacle section, it is further determined whether this obstacle is a regulation requiring emergency evacuation (S
206). If emergency evacuation is required, it is determined whether or not the vehicle is traveling in this restricted section (S210).
For example, the evacuation information as shown in FIG. 5 is displayed (S21
0), the display for prompting the lighting of the above-mentioned hazard lamp is performed (S211). Also, if you are not traveling in the regulated section,
The regulation information such as "accident in tunnel, prohibition of entry" is displayed (S212). In step S206, if the received information on traffic congestion / regulation is not related to emergency evacuation, it is determined whether there is a rest facility in the obstacle section (S).
214). If there is a rest area such as a service area,
Display information about rest facilities as shown in. If there is no rest facility, it is determined whether the information about the length of traffic jam and the required transit time has been received (S218). If this information has been received, a display as shown in FIG. 2 is displayed to inform the passenger of the degree of congestion (S220). If there is no information such as the length of the traffic jam, it is determined whether the information about the cause of the traffic jam has been received (S222).
A display indicating the cause of the traffic jam and the like is performed (S224).

When the above conditions are not satisfied, only the information display by the map is performed, and the character information display section 114 is displayed.
The passengers will not be notified of the information. If it is determined in step S204 that the vehicle is not traveling in the obstacle section, the search for a detour such as the above-described conventional device is started automatically or by an instruction from the passenger (S226).

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

When the external information is received by the beacon receiver 36 or the FM multiplex receiver 34, the traffic jam / restricted section detection unit 52 determines whether the information about the traffic jam is received, and the received traffic jam is stored in the route in advance. Part 3
It is determined whether it is on the route stored in 0. When there is a traffic jam on the route, the information selection unit 54 first selects the information about the rest facility and the traffic jam elimination predicted time from the external information, and displays this on the display unit 26. For example, "○○ drive-in 2 km" is displayed.

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

FIG. 8 shows an example of this search result. The own vehicle 102 is heading toward the intersection 120 and the road 122 in the center of the screen.
Is in progress. This road is congested up to an intersection 120, which is indicated by a congestion display symbol 124. Although there are roads 126 and 128 that run parallel to this road, the traffic jam display 124 is also displayed on these roads. When the passenger gives an instruction to re-search, the route to the top 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 for three routes including a route that makes a left turn at the intersection 130 and detours along the arrow A, a route that makes a left turn at the intersection 130 and detours along the arrow B, and the original route 132 Has been done. 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 cannot be shortened even if the route is taken through another route.

FIG. 9 is a flow chart concerning the search for a detour according to this embodiment. When the beacon receiver 36, the FM multiplex receiver 34, and the like receive information regarding traffic jams and regulations from the outside, it is determined whether the traffic jams or the like are on a route that has been searched in advance (S230). If there is a traffic jam section on the route, the passenger waits for a passenger's search instruction from the input unit 28 (S232). Then, the start point of this traffic jam is determined (S234). A search for a detour leading to this leading point is performed, and it is determined whether a detour route exists (S236). When there is a detour, the required time for each of the detour searched and the preset route is displayed. The passenger can determine which route to select by looking at the display of the required time. If no detour exists, a message such as "There is no detour" is displayed (S240).

Further, in FIG. 9, the case where the route is set in advance is described, but when the route is not set, it is judged whether the own vehicle is traveling in a traffic jam section or the like and the detour search is performed. It is also preferable to use the judgment of the start.
Therefore, in this case, it can be understood that a step of determining "whether the 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 device of this embodiment notifies the passenger of two methods, that is, a method of avoiding traffic congestion by taking a detour and a method of avoiding traffic congestion by taking a break and waiting for traffic congestion to be resolved. You can The passengers can be informed of a plurality of methods so that they can make a wider choice.

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

Further, by setting the head of the congestion / restricted section which is the target when searching for the detour as the waypoint, it is possible to return to the initially searched route at an early point. Therefore, the passenger can travel with a minimum amount of information about the new route, and the burden is reduced.

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

Further, although all the above-mentioned embodiments describe the case where the current position is measured by GPS or the like,
It is also possible to measure the current position with a beacon.
That is, if the code identifying the source of the beacon is included in the information from the beacon, the position of the host vehicle can be identified by the code of the beacon. Therefore, it is understood that a device for detecting the current position of the own vehicle by the code of the beacon is also included in the scope of the present invention, except for the components related to the navigation system by GPS or the like in each of the embodiments described above.

[0059]

As described above, according to the present invention, the passenger can be surely notified of the information regarding the target traffic congestion and traffic regulation.

In particular, according to the first aspect of the present invention, the passenger can deal with the traffic jam based on the information by providing the information about the traffic jam even in the section without the detour. You can

According to the second aspect of the invention, the passenger can know in advance the time required to pass the traffic jam,
It is possible to reduce annoyance without knowing how long the traffic will continue.

According to the third aspect of the invention, the passenger can judge the degree of the traffic jam based on the cause, and can predict the time for solving the traffic jam.

According to the invention of claim 4, the passenger can evacuate from the traffic jam based on the information for avoiding the traffic jam.

According to the fifth aspect of the invention, the passenger can take a break at the notified rest facility and wait for the cancellation of the traffic jam. In addition, it is possible to determine how long to take a break based on the informed predicted congestion elimination time.

Further, according to the invention of claim 6, since the information on the traffic regulation requiring the emergency evacuation is notified, the passenger can take an appropriate evacuation.

Further, according to the invention of claim 7,
Since the rest facility and the estimated time to clear the congestion are notified, a method of avoiding the congestion other than taking a detour can be to take a rest at the rest facility until the congestion is resolved.

Further, according to the invention described in claim 8,
When searching for a detour, the first point of the congestion is set as the waypoint and the route to this waypoint is searched again, so the route that avoids the traffic congestion is displayed without drastically changing the original route and boarding is carried out. Information that is easy for a person to understand is provided.
