Unlike VICS, which notifies general traffic information, AHS continuously obtains detailed road, person, and car information from sensors and cameras located at specific places requiring special attention such as intersections and curves. The target is a system that obtains information through discretely arranged short range communication (DSRC) and provides various services to the driver. AHS support services include forward obstacle collision prevention, curve entry danger prevention, lane departure prevention, encounter collision prevention when approaching / starting, right turn collision prevention, crosswalk pedestrian collision prevention, road surface information provision, front stop vehicle・ Providing information on low-speed vehicles.
[0005]
Among these support services, an example of a right-turn collision prevention support service is shown in FIG. When a right turn is instructed by navigation in a car that has approached an intersection, a screen 131 for instructing a right turn is displayed on the navigation screen, and a voice instruction is given "300m ahead, right direction" 131a. When you get close to the intersection, you can get information about the straight-ahead vehicle in the lane you are facing. Is done. When you enter the intersection, you can get pedestrian information on the right pedestrian crossing. If the pedestrian is crossing, a screen 133 with a pedestrian is displayed, and a voice warning is given, “Pon, there is a pedestrian” 133a. .
[0006]

[0017]
<Example of AHS information for right turn at intersection>
FIG. 2 is a diagram illustrating a configuration in the vicinity of an AHS intersection to which the present embodiment is applicable. The AHS shown in FIG. 2 is a system that supports the prevention of collision with an oncoming vehicle traveling on an oncoming road when the host vehicle turns right (including waiting for a right turn) at an intersection.
[0018]
In the configuration shown in FIG. 2, at the intersection of at least one lane road R1 where a traffic signal is installed and at least one lane road R2 intersecting this road R1, and in the vicinity of this intersection (for example, 30 m ) On the road side of the vehicle R1 on the road lane side of the host vehicle V1, and on the road side of the vehicle lane side of the other vehicle (opposite vehicle) V2 facing the road lane of the host vehicle V1 on the road R1.

Is provided.
[0019]
Here, the road R1 includes a traveling road including a traveling lane on which the host vehicle V1 travels and an oncoming road including at least one lane (opposing lane) on which the oncoming vehicle V2 travels.
[0020]
The base point 23 is a base point detector mounted on the host vehicle V1 with unique identification information (hereinafter referred to as a base point ID) and a provision ID (described later) for identifying provision information associated with the base point ID. The vehicle V1 detects that the vehicle has passed the base point 23 by the base point detector, and acquires the base point ID and the provision ID from the base point 23 when the base point passes.
[0021]
The base point 23 is a reference position for measuring the travel distance of the host vehicle V1 from the base point 23 to the intersection. The travel distance from the base point 23 to the intersection is a reference for specifying the provision information receiving section A1 by the roadside antenna 21.
[0022]
The vehicle detection sensor 22 detects another vehicle (oncoming vehicle) V2 existing on the opposite road of the host vehicle V1 in the predetermined detection range B1 before the intersection from the vicinity of the intermediate point (point Z) in the intersection, and the predetermined detection range B1 The position information of the other vehicle V2, vehicle speed information, vehicle type information, and the like are detected and transmitted to the AHS base station CPU 20.
[0023]
Here, the point Z that is near the intermediate point in the intersection is the reference position (T = 0, L = 0) of the expected arrival time T to the intersection of the oncoming vehicle in the present embodiment.
[0024]
Similarly to the base point 23, the roadside antenna 21 has unique identification information (hereinafter referred to as a provision ID) and a base point ID associated with the provision ID, and is detected by the base point ID and the vehicle detection sensor 22 together with the provision ID. The information on the position information, vehicle speed information, vehicle type information, road shape (the state of the intersection and the surrounding gradient, the lane width, the number of lanes, etc.) is transmitted to the host vehicle V1 in the provision information receiving section A1. (provide.
[0025]
The information on the road shape is not obtained via the roadside antenna 21, but is obtained from, for example, a map information database that is mounted on the host vehicle V1 and is referred to when displaying a road map or guiding a route. May be.
[0026]
That is, in the provided information receiving section A1, the road-to-vehicle communication device 16 mounted on the host vehicle V1 receives the base point ID, provided ID, position information of the other vehicle V2, vehicle speed information, vehicle type information, road, Information on the shape (hereinafter collectively referred to as provided information) is received, and the AHS in-vehicle CPU 10 uses the display device 14 and / or the speaker 15 based on the received provided information to determine the vehicle V1. Control processing for information provision (information presentation) to passengers is performed. This information presentation includes output of a voice message or warning sound from the speaker 15 in addition to an image or character display using the display device 14.
[0027]
Moreover, in this embodiment, AHS base station CPU20 (roadside antenna 21) can provide said provision information for every lane which comprises the predetermined detection range B1 of the oncoming road where the other vehicle V2 drive | works, Furthermore, When there are a plurality of vehicles on the same lane within the predetermined detection range B1, the information related to the other vehicle V2 can be provided up to a predetermined number.
[0028]
Furthermore, in the present embodiment, the AHS base station CPU 20 (roadside antenna 21) can provide the lateral position of each other vehicle V2 on the same lane within the predetermined detection range B1 (for example, the distance from the road shoulder). It shall be possible.
[0029]
In the above system, contrary to the case shown in FIG. 2, the other vehicle V2 is also an information provided vehicle similar to the own vehicle V1, and the other vehicle V2 uses the information provided by the own vehicle V1 traveling on the oncoming road as roadside information. The signal is received from the antenna 21.
[0030]
The oncoming vehicle and road information from the AHS base station CPU 20 is continuously transmitted every 100 ms in the provided information receiving section A1 (in the intersection and 30 m before the intersection), but this information is required only for right-turn cars. Therefore, in general, the blinking instruction of the right turn signal is detected and the oncoming vehicle and road information reception start time is set. Further, the information service is terminated by the travel distance from the service start.
[0031]
In the oncoming vehicle and road information received by the right turn vehicle from AHS, the information used in the present embodiment includes the shape of the intersection, the position of the approaching vehicle (oncoming vehicle), the speed, the traveling lane, the passing vehicle (two-wheeled oncoming). Vehicle) position, speed, and driving lane information. The information update cycle is 100 ms, and the position information is in 1 m increments. Further, as a feature of AHS, the processing delay time is 0.3 ms, and the reception distance is within 1 km.
[0032]
In addition, about acquisition of intersection shape information, you may use the intersection information database which the own vehicle has, and the intersection information sent as other communication information.
[0033]
<Example of detection of travel lane of this embodiment>
Information used for display of right turn support information and its regulation in the present embodiment includes right turn blinker information and travel lane information. The right turn turn signal information can be easily obtained by the detection of the turn signal operation sensor 11, but the travel lane information needs to be recognized by the own vehicle.
[0034]
In the present embodiment, the vehicle controller recognizes the travel position information based on the GPS data and the intersection information stored in the route guidance DB 13 and the intersection information obtained from the AHS.
[0035]
Note that the present invention is not limited to the above example, and it is also conceivable to obtain travel lane information from the outside or from a lane marker. This embodiment is characterized by how the travel lane information is used, and the acquisition method is not limited.
[0036]
<Example of lane change start and completion detection in this embodiment>
FIG. 3 is a diagram illustrating a detection example of the start and completion of the lane change in the present embodiment.
[0037]
The vehicle body 30a operates the right turn turn signal to start a lane change (31). In the vehicle body 30b, the vehicle body has completely moved to the right lane. However, the vehicle body 30b is still undergoing a lane change, and the vehicle body is inclined with respect to the lane direction. At the time of the vehicle body 30c, the steering wheel is recut to turn the vehicle body in the lane direction. In the present embodiment, the time point 32 when the vehicle body is parallel to the lane direction is the completion of the lane change. In other words, (1) the vehicle body moves completely into the adjacent lane, (2) the vehicle body direction is the same as the lane (the yaw angle with respect to the lane is within a predetermined range) It is a condition. If a turn right turn signal is operated after the vehicle body 30d (after completion of the lane change), it is recognized as a right turn.
[0038]
The inclination between the vehicle body and the lane can be detected by, for example, an in-vehicle travel lane detection camera that can recognize the image of the lane and calculate the inclination.
[0039]
<Example of restricting display of right turn support information in this embodiment>
Hereinafter, several examples of the right turn support information display restriction by the traveling lane and the right turn turn signal will be described. In the following example, the operation at the lane change and after the completion will be described, but each processing is not limited to the lane change.
[0040]
With reference to FIG. 4, the following examples (1) to (3) will be described.
[0041]
(1) Provide right turn support information during the right turn turn signal operation in the rightmost lane.
[0042]
For example, when the traveling lane in which the vehicle 40 is traveling is not the rightmost lane, provision of right turn support information is restricted at least until the lane change completion 42 even during a right turn blinker operation.
[0043]
Even if the turn signal blinker is operated after the host vehicle enters the provided information reception section, if the right lane is not detected in the lane detection, the oncoming vehicle information is not presented. When the lane change is completed and the rightmost lane is detected by lane detection, the restriction on information presentation is released. Thereafter, if a right turn turn signal is operated, information is presented.
[0044]
However, if a right turn dedicated lane is installed separately from the main lane, presentation of oncoming vehicle information is restricted until the lane change to the right turn dedicated lane is completed regardless of the lane detection. Data received from the vehicle or from the in-vehicle map DB).
[0045]
After completing the lane change, the oncoming vehicle information is presented on the premise of the right turn blinker operation state, but if you make a lane change to the right turn dedicated lane within the provided information reception section, it is determined that you will turn right at the intersection, (1) Even if the turn signal is not released (the turn signal continues to come out), or (2) even if the right turn signal is released at the time of the lane change completion, it is assumed that the vehicle will turn right as soon as the lane change is completed. Present.
[0046]
(2) From the completion of the lane change 42 until the predetermined time t / distance passage 43, presentation of oncoming vehicle information is prohibited.
[0047]
For example, a predetermined time / distance elapses after the lane change is completed in order to make the determination of whether to make a right turn (when making a lane change within the data provision information receiving section, turn right at the intersection) The presentation of oncoming vehicle information is prohibited.
[0048]
That is, (1) if the winker is not released (the winker continues to come out), the driver determines the end of the lane change and prohibits the presentation of information for the time / distance required to release the winker. (2) If the right turn turn signal has been released when the lane change is completed, the presentation of information is prohibited only for the time / distance required for the driver to operate the right turn turn signal again. If the right turn turn signal is operated when the prohibition is released, the oncoming vehicle information is presented.
[0049]
Of the time / distance, the prohibition lasts longer. For example, the time when the flow is good is about 2 seconds, and the distance when the traffic is interrupted is about 10 m.
[0050]
(3) Oncoming vehicle information is not allowed to be presented from the intersection until a predetermined time / distance 44.
[0051]
For example, in order to remove the uncertainty of determining whether to make a right turn (when making a lane change within the data provision information reception section, turn right at the intersection), until approaching a predetermined time / distance before the intersection, Prohibition of oncoming vehicle information is prohibited. If the turn right turn signal is operated when the prohibition is released, the oncoming vehicle information is presented.
[0052]
Note that the predetermined time / distance is the time / distance in which the oncoming vehicle information can be recognized before the host vehicle becomes the head of the right turn waiting vehicle, and the prohibition continues for a longer time. For example, the recognition time is about 4 seconds, and the distance behind the line of the parked right turn waiting vehicle is about 10 m.
[0053]
(4) When the navigation route guidance is not a right turn instruction, presentation of oncoming vehicle information is prohibited.
[0054]
Each time the route guidance unit provides guidance to the driver, the route guidance unit sends guidance data (the position of the intersection to be guided and the content of the guidance) to the right turn determination unit. The right turn determination unit collates the position of the vehicle with the position of the guidance intersection and the position of the intersection targeted for the right turn support service, and confirms the guidance content at the target intersection. The guidance contents at the service target intersection may be inquired from the right turn determination unit to the route guidance unit.
[0055]
If the guidance does not indicate a right turn (including no guidance during route guidance), it is determined that the vehicle will not turn right, and oncoming vehicle information presentation such as after completion of a lane change is prohibited. However, if a right turn turn signal is newly operated after completing a lane change, the prohibition is canceled and oncoming vehicle information is presented.
[0056]
(5) During vehicle acceleration, presentation of oncoming vehicle information is prohibited.
[0057]
When accelerating after completion of a lane change (determined by vehicle acceleration, accelerator pedal depression amount, etc.), it is determined that there is no intention to turn right (for example, a lane change for avoidance), and presentation of oncoming vehicle information is prohibited.
[0058]
(6) The above restrictions will be lifted in the intersection.
[0059]
In FIG. 5, when the vehicle body 50 enters the intersection 51, oncoming vehicle information is presented if the right turn turn signal is operated.
[0060]
(7) It should be noted that the above prohibition of oncoming vehicle information is for the purpose of presenting oncoming vehicle information while the right turn signal indicator is operated due to a lane change etc. When the driver turns the right turn signal while driving on the lane, it is determined that the driver is making a right turn and the oncoming vehicle information is presented. In the case of a right turn dedicated lane, oncoming vehicle information is presented even if the right turn turn signal is not operated.
[0061]
<Example of Operation Procedure of Vehicle Information Providing Device of Present Embodiment>
FIG. 6 is a flowchart illustrating an example of an operation procedure of the vehicle information providing apparatus according to the present embodiment.
[0062]
First, when the vehicle enters the oncoming vehicle data reception area (provided information reception section A1 in FIG. 2) in step S61, it is determined whether or not the vehicle is within the reception area in step S62. Determination outside the area is usually determined that the vehicle has gone out of the area with the travel distance from the base point. Alternatively, when making a right turn, the end of the right turn may be taken out of the area. If it is within the reception area, the process proceeds to step S63 to determine whether or not the right turn turn signal is being operated. If the right turn signal is not being operated, the process returns to step S62. If the right turn turn signal is being operated, it is determined in step S64 whether or not the driving lane is the right lane (this determination changes according to the shape of the intersection, and the right lane is designated or specified at the intersection of three or more lanes one way. The right turn lane is judged at the intersection where the right lane and the right turn lane are provided).
[0063]
If it is the right lane, oncoming vehicle information is presented (updated if already presented) in step S65. In step S66, the process waits for the right turn to end. If not, the process returns to step S65 to update the oncoming vehicle information. If the end of the right turn is determined, the oncoming vehicle information presentation is ended in step S67. Note that the determination of the right turn end is, for example, the travel distance of the vehicle after recognizing the DSRC base point in FIG. 2 (for example, 35 or 40 m exceeding 30 m of the provided information receiving section A1), or the vehicle by GPS or the like Judgment can be made from the position in the intersection.
[0064]
If it is not the right lane in step S64, the process proceeds to step S68 to determine whether or not the lane change has moved to the right lane. If there is no lane change, the process ends without presenting oncoming vehicle information.
[0065]
If the vehicle has moved to the right lane due to a lane change, it is determined whether or not a predetermined condition is met in step S69, and the presentation of oncoming vehicle information is prohibited under the predetermined condition. Can be ignored, the process proceeds to step S65 to present oncoming vehicle information.
[0066]
The oncoming vehicle information presentation conditions in step S69 are opposite to the various presentation prohibition conditions described above. Here, to summarize briefly, as shown in FIG. 6, (1) right turn signal operation (new operation by the driver, not the instruction state), (2) in the right turn dedicated lane, (3) lane change complete Elapse of a predetermined time / distance from (4) within a predetermined time / distance from the intersection, (5) navigation guidance to turn right, (6) no acceleration, and so on.
[0067]
FIG. 7 is a flowchart showing an example of a processing procedure in which the conditions in step S69 are combined. The priorities of the above conditions are not limited to this example, and each condition may be used independently, and FIG. 7 is merely an example of the procedure.
[0068]
First, in step S691, it is determined whether the lane is for a right turn. If it is a right turn lane, the oncoming vehicle information is presented without the instruction or operation of the right turn turn signal. In step S692, it is determined whether or not the driver has operated a right turn turn signal. When the driver turns the turn signal right, the oncoming vehicle information is presented without seeing the prohibition conditions. In step S693, it is determined whether a right turn turn signal is being instructed. Oncoming vehicle information is not presented unless instructed.
[0069]
If the turn right turn signal is instructed, it is determined in step S694 whether or not the vehicle is in the intersection. If the vehicle is in the intersection, the oncoming vehicle information is presented regardless of the travel lane. In step S695, it is determined whether the navigation instruction is a right turn. If the navigation is not a right turn instruction, no oncoming vehicle information is presented.
[0070]
In step S696, it is determined whether the time is within a predetermined time / predetermined distance after completion of the lane change, and if it is within the predetermined time / predetermined distance, no oncoming vehicle information is presented. In step S697, it is determined whether the vehicle is within a predetermined time / predetermined distance from the intersection. If it is not within the predetermined time / predetermined distance, no oncoming vehicle information is presented.
[0071]
As described above, the presentation of the oncoming vehicle information and the prohibition of presentation in the provided information reception section A1 heading for the intersection have been described under various conditions. However, the main point of the present invention is that it is necessary to maintain the presentation of the necessary oncoming vehicle information. By eliminating the presentation of no oncoming vehicle information, the safety of driving at the intersection of the driver is enhanced. The scope of the present invention is not limited to the scope of the above-described embodiment, and the technical idea thereof is at the intersection. The present invention is widely applicable to oncoming vehicle information presentation methods, and the present invention includes these methods.
[0072]
【The invention's effect】
According to the present invention, it is possible to provide a vehicle information providing apparatus that contributes to a driver's safe driving without unnecessary presentation while maintaining necessary presentation of oncoming vehicle information based on information from an AHS base station.
[0073]
For example, unnecessary presentation of oncoming vehicle information is eliminated until the lane change is completed, thereby contributing to the driver's safe driving.
[0074]
Further, during a predetermined time or a predetermined distance after completion of the lane change, unnecessary presentation of oncoming vehicle information is eliminated, which contributes to the driver's safe driving.
[0075]
Moreover, unnecessary presentation of oncoming vehicle information is eliminated at a position before a predetermined time or a predetermined distance from the intersection, thereby contributing to the driver's safe driving.
[0076]
Further, when the navigation does not instruct a right turn, unnecessary presentation of oncoming vehicle information is eliminated, which contributes to a driver's safe driving.
[0077]
Also, when accelerating, unnecessary presentation of oncoming vehicle information is eliminated, which contributes to the driver's safe driving.
[0078]
Further, in the intersection, when there is an instruction of a right turn turn signal, the necessary presentation of oncoming vehicle information is maintained to contribute to the driver's safe driving.
[0079]
Further, when there is an operation of turn right blinker instruction while traveling on the right lane, the necessary presentation of the oncoming vehicle information is maintained to contribute to the driver's safe driving.
