Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an on-vehicle device that obtains service information from a road side to support traveling. The present invention is suitable for AHS (Advanced Cruise-Assist Hig).
hway Systems: driving assistance road system), but not limited to in-vehicle devices.

[0002]

2. Description of the Related Art In recent years, ITS (Intelligent Transport)
Systems: Advanced transportation system (AHS) is under development, and one of the ITS is AHS (Advanced Cruise-As).
sist Highway Systems: Driving support road systems). In AHS, a system on the road side (infrastructure system) and an in-vehicle device are connected by communication, and they are integrated to provide driving support. Driving assistance is typically information provision and vehicle control (vehicle speed, etc.). In the present invention, the warning to the driver is considered to be included in the information provision. Here, information provision will be mainly described.

At present, in AHS, front obstacle collision prevention, curve entry danger prevention, lane departure prevention, encounter collision prevention (assistance at approaching intersection and assistance at call origination), right turn collision prevention (right turn vehicle support), pedestrian crossing. Support functions such as pedestrian collision prevention have been proposed.

[0004]

In AHS, a plurality of types of support functions may be provided at the same place. Therefore, a composite event may occur in which a request to perform a certain support and a request to perform another support occur at the same time. When this complex event occurs, it is desirable to provide appropriate assistance to the driver. However, until now, regarding the in-vehicle device of AHS, the complex event of heterogeneous support has not been considered.

Here, paying attention to the prevention of crossing pedestrian collision, consider a case where a composite event of pedestrian information and other information occurs.
The different information is, for example, information of an oncoming straight vehicle at a right-turn intersection. The car is about to turn right, an oncoming car is passing in front of the car, and there is a pedestrian on the pedestrian crossing. The presence of an oncoming vehicle is an event on the near side as seen from the vehicle, and the presence of a pedestrian is an event on the far side as seen from the vehicle.

When such a complex event occurs, if the oncoming vehicle information and the pedestrian information are presented to the driver as they are as in the case of the individual occurrence of each event, the driver's attention cannot be sufficiently attracted. Can be. However, in order to improve safety, which is the purpose of AHS, it is desirable to provide appropriate information in terms of HMI (Human Machine Interface) when such a complex event occurs.

In the above example, the other information combined with the pedestrian information is the oncoming vehicle information. The same problem may occur when the separate information is vehicle information (forward passage) at the temporary stop location. In this case, the presence of a pedestrian is an event on the front side as viewed from the vehicle, and the presence of a vehicle passing in front is an event on the other side as viewed from the vehicle.

Further, the above problem is not limited to pedestrian information. When both an event on the front side of the vehicle and an event on the other side of the vehicle occur, appropriate information provision is similarly required.

The present invention has been made in view of the above problems, and an object thereof is to provide an in-vehicle information providing device capable of providing appropriate information even when a composite event occurs.

[0010]

[Means for Solving the Problems] (1) In order to achieve the above object, the present invention obtains service information from the road side in a service area set on the road and provides information for driving assistance to an occupant. in-vehicle information providing device that performs hand, means for providing a pedestrian information on pedestrians, and means for providing different information different from the pedestrian information, the step
Providing personal information or other information separately requested
Sometimes the above is provided so that each is provided in a predetermined form
To control both the pedestrian information and the other information.
About the information of one side when the provision of one side is requested
When the event of
Different form compared to the predetermined form when provided in
And means for controlling the means for providing . The request to provide information means that it is recognized that the system needs to provide information in some form.

According to the present invention, when a complex event of providing pedestrian information and another information occurs, the form of providing information is changed, so that the occurrence of the complex event can be effectively notified to the driver. The change in the form of information provision referred to here is a change that informs the driver of the occurrence of a complex event, and is not simply providing a plurality of information at the same time (for example, providing two information by split screen display).

[0012]

(2) In one aspect of the present invention, the different information is oncoming straight vehicle information at a right-turn intersection. The pedestrian information and the oncoming straight ahead vehicle information are provided before the oncoming straight ahead vehicle passes through the right-turn intersection, and the pedestrian information is emphasized after the oncoming straight ahead vehicle has passed compared to before the passing.

This aspect relates to a complex event of pedestrian information and an oncoming vehicle at a right-turn intersection. After receiving the information on the oncoming straight ahead vehicle and the pedestrian, the driver first pays attention to the oncoming straight ahead vehicle, which is the front side event, and waits for the passage. When the oncoming straight vehicle passes, the driver's consciousness level for the pedestrian information beyond that may be lower than that at the time of the first information presentation. In the present invention, since the pedestrian information is emphasized and presented at this stage, the pedestrian information can be surely recognized by the driver, and the safety can be further improved.

More preferably, when it is determined that the vehicle is going to make a right-turn action after the oncoming straight vehicle has passed the right-turn intersection, the degree of emphasis is further increased as compared with the provision of the emphasis of the pedestrian information. The following emphasis will be provided. According to this aspect, when the driver attempts to make a right turn, the degree of emphasis is increased even though the above-described emphasis presentation has been performed.
More appropriate information can be transmitted.

(3) In another aspect of the present invention, the additional information is vehicle information at a temporary stop location. And
Before the pedestrian crosses the front of the vehicle, the pedestrian information and the vehicle information are provided, and after the pedestrian crosses, the vehicle information is emphasized as compared with before the pedestrian crossing.

This aspect relates to a complex event of pedestrian information and a vehicle passing ahead at a temporary stop location. Unlike the above aspect, the presence of a pedestrian is the front side event in this aspect.
The effect of this mode is almost the same as that of the above mode (2).

That is, after receiving the information on the pedestrian and the passing vehicle, the driver first pays attention to the pedestrian, which is the front side event, and waits for the passage. When the pedestrian passes by, the driver's level of consciousness of the passing vehicle beyond that may be lower than that at the time of the first information presentation. In the present invention, since the passing vehicle is highlighted at this stage, the driver can be surely recognized by the passing vehicle, and the safety can be further improved.

More preferably, when it is determined that the vehicle enters the action of passing the suspension place after the pedestrian has passed in front of the vehicle, the degree of further enhancement as compared with the provision of enhancement of the vehicle information. To provide an increased secondary emphasis. According to this aspect, when the driver tries to move ahead of the temporary stop despite the above-described emphasis presentation, the degree of emphasis is increased, so that more appropriate information can be transmitted.

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention (hereinafter referred to as embodiments) will be described below with reference to the drawings. In this embodiment, the present invention is based on AHS (Advanced Cru).
ise-Assist Highway Systems)
Applied to.

FIG. 1 shows the structure of an on-vehicle device for driving assistance according to this embodiment. This in-vehicle device functions as an AHS integrally with an infrastructure system (roadside system). The vehicle-mounted device 1 of the present embodiment performs an information providing process as driving support. In the present invention, the information provision also includes a warning.

As shown in FIG. 1, the in-vehicle device 1 includes an information providing ECU 10, a base point marker detector 12, and a road-vehicle communication device 1.
4 and a vehicle speed sensor 16. Base point marker detector 12
The (marker sensor) detects a service-in marker and a service-out marker (base point marker) installed on the road. The base point marker detector 12 has a receiver and receives the radio wave emitted by the base point marker. In addition, the road-to-vehicle communication device 14
Service information is received from a transmitter installed on the road side in association with the service-in marker. The vehicle speed sensor 16 sends vehicle speed information to the information providing ECU 10. The vehicle speed sensor 16
For example, a pulse signal indicating the wheel rotation speed is generated. In addition,
The vehicle speed information may be obtained from a configuration other than the vehicle speed sensor 16, such as another ECU.

When the service marker is detected by the base point marker detector 12, the information providing ECU 10 uses the service information obtained by road-to-vehicle communication to provide information for driving assistance. The display 20 and the speaker 22 as output means are used to provide information to the driver. Character information may be displayed on the display 20, and images representing roads, intersection shapes, etc. may be displayed. A notification sound may be output from the speaker 22,
Audio information may be output.

The information providing ECU 10 has various AHS information providing functions. In FIG. 1, "pedestrian information providing unit 30", which is three of those information providing functions, is shown.
(Prevention of crossing pedestrian collision), "Oncoming straight ahead vehicle information provision section 3
2 "(Right turn collision prevention) and" Passing vehicle information providing section 3 "
4 "(prevention of collision at the head of the head) is shown. The passing vehicle information is information on vehicles on the priority road at the temporary stop location. Furthermore, the information providing unit ECU 10 is provided with a display form change processing unit 36. This display form change processing unit 3
As will be described later, 6 suitably functions when two types of information provision requests occur (when a composite event occurs). The request to provide information means that it is recognized that the system needs to provide information in some form.

Further, information indicating the accelerator operation and the brake operation is sent from the accelerator switch 24 and the brake switch 26 to the information providing ECU 10. These pieces of information are used to determine whether or not the driver has performed a start operation.

"Right-turn intersection" Next, with reference to FIG. 2, an infrastructure system, that is, a roadside system will be described. FIG. 2 conceptually shows an infrastructure system of an intersection with a right turn lane. This system provides the vehicle-mounted device with information for preventing a right-turn collision and for preventing a crossing pedestrian collision.

In FIG. 2, the right-turn vehicle X is stopped in the right-turn lane. The measurement range 50 (for an oncoming vehicle) is set to the oncoming lane. An oncoming vehicle 52 within the measurement range 50 is detected by the road condition detection device 54. The detection device 54 is
Examples include visible cameras, infrared cameras, and infrared sensors. The infrastructure control device 56 identifies the vehicle within the measurement range 50 based on the information sent from the detection device 54. For example, image processing is performed on an image obtained from a visible camera to find the vehicle in the image.

A measuring range 60 (for pedestrians) is set so as to cover each of the four pedestrian crossings at the intersection. A pedestrian 62 within the measurement range 60 is detected by the pedestrian detection device 64. The detection device 64 is also a visible camera or the like. The infrastructure control device 56 identifies a pedestrian based on the information obtained from the detection device 64.

The transmission information generator 58 sends the transmission information to be transmitted to the vehicle to the transmitter 66. The transmitted information is the oncoming vehicle,
Contains pedestrian and road alignment information. Oncoming vehicle information preferably includes the position, size, and speed of the oncoming vehicle. The pedestrian information includes the position of the pedestrian. The pedestrian information may also include a bicycle. The road alignment information is read from the road alignment storage unit 68. It is preferable that the transmission information further includes useful information such as road surface conditions. The transmission information is transmitted from the transmitter 66 to the information communication range 70. The transmission interval currently set by AHS is 100 msec.

A service-in marker 72 is installed at the start of the information communication range 70. The service-in marker 72 is a radio wave marker and has a role of instructing the vehicle to enter the service providing area. Service in marker 72
Provides the vehicle with further necessary information. Further, the vehicle can specify the position along the lane direction and the own vehicle traveling lane (right turn lane) using the service in marker 72.

In the example of FIG. 2, the vehicle is about to pass the service-in marker 72. When the vehicle passes through the service-in marker 72, the vehicle-mounted device receives the information sent from the infrastructure and provides the driver with the information. Here, straight ahead vehicle information and pedestrian information are provided. As an example of "provision of straight-ahead vehicle information", the shape of an intersection is displayed on the display, and the oncoming straight-ahead vehicle is superimposed and displayed on it. Along with the display, the approach of a straight ahead vehicle can be notified by voice or notification sound.
As an example of the "pedestrian information", the shape of the intersection is displayed on the display, and the pedestrian is displayed on the intersection shape.
Along with the display, the approach of a straight ahead vehicle can be notified by voice or notification sound.

"Composite Event (Pedestrian-Straight Vehicle)" By the way, the above-mentioned complex event of pedestrian information and straight-ahead vehicle information may occur. This is the case when a straight ahead vehicle is approaching and a pedestrian is passing through a pedestrian crossing. When this composite event occurs, the present embodiment provides the following suitable information.

Referring to FIG. 3, in S10, it is determined whether or not the provision of straight ahead vehicle information is requested, that is, whether or not there is a straight ahead vehicle. If S10 is NO, S1
At 2, it is determined whether or not a pedestrian is present. Here, we mainly consider pedestrians on a pedestrian crossing on the right-turn route. S
If 12 is NO, the process returns to S10, and if S12 is YES, the pedestrian information is provided as usual in S14. On the other hand, even when there is a straight ahead vehicle in S10, it is determined in S16 whether a pedestrian exists. If S16 is NO,
In S18, the straight-ahead vehicle information is provided as usual.

If S16 is YES, it is required to provide both the straight-ahead vehicle information and the pedestrian information. Therefore, S20
Will provide information for both straight-ahead vehicles and pedestrians. Here, for example, a straight vehicle and a pedestrian are drawn on the intersection figure.

The information provision in S20 is continued until it is determined in S22 that the straight ahead vehicle has passed the intersection. When a straight ahead vehicle passes through the intersection, it is determined in S24 whether or not a pedestrian still exists, and if there is no pedestrian, the process returns.

If there are still pedestrians in S24, it is determined in S26 whether or not the vehicle is about to make a right turn action. A right-turn action is a vehicle approaching an intersection and trying to make a right turn.

The right-turn action is determined based on, for example, vehicle speed information. When the stopped right-turning vehicle starts, the vehicle speed becomes zero and it is determined that the right-turning action has occurred. It may be determined that the right-turn action has occurred when the accelerator is turned on or when the brake is turned off. of course,
It may be determined whether these multiple events have occurred.
Alternatively, the right-turn action may be determined from the vehicle position information. The vehicle position is obtained by distance integration using the service-in marker as a reference.

If S26 is NO, the process proceeds to S28, and pedestrian information is emphasized and provided. Here, the pedestrian information may be emphasized as compared with the case where the pedestrian information is provided alone. Emphasis provision is to increase the weight of information provision,
Providing information prominently (same herein). For example, blinking display of a pedestrian image is performed, and voice guidance or notification sound is output.

If S26 is YES, the process proceeds to S30,
Secondary emphasis of pedestrian information will be provided. In the secondary emphasis provision, the degree of emphasis is further increased compared to the emphasis provision in S28. For example, an alarm sound different from the notification sound of S28 is output, and the alarm display is also displayed on the display.

The process of FIG. 3 is continued until the service out marker installed at the end point of the intersection is detected.

FIG. 4 shows a specific example of changing the above-mentioned information providing form. In FIG. 4A, before a straight ahead vehicle passes, both a straight ahead vehicle and a pedestrian are displayed on the display. As shown in FIG. 4B, when a straight-ahead vehicle passes by, the pedestrian is highlighted by blinking. It is also preferable to change the color of the pedestrian or increase the size. In FIG. 4B, the presence of a pedestrian is notified by voice guidance.
Furthermore, as shown in FIG. 4C, when the vehicle is about to start, a warning sound is output as secondary emphasis. Although not shown, it is also preferable to display a screen indicating that an alarm has occurred.

As described above, in the present embodiment,
When a compound event of pedestrian information and straight-ahead vehicle information occurs,
The form of information provision is changed. Initially, information on oncoming vehicles and pedestrians will be provided together. The driver who receives these pieces of information first pays attention to the oncoming straight ahead vehicle, which is the near side event, and waits for the passage. When the oncoming straight vehicle passes,
It is possible that the driver's level of consciousness for the pedestrian information beyond that is lower than that at the time of the first information presentation. At this time, in the present embodiment, since the pedestrian information is emphasized and presented, the pedestrian information can be surely recognized by the driver, and the safety can be further improved.
Further, in the present embodiment, the degree of emphasis is increased as secondary emphasis when the driver attempts to make a right turn, despite the above-described emphasis presentation, so that more appropriate information transmission can be performed.

"Temporary stop" (prevention of collision at encounters) Next, another embodiment of the present invention will be described.

In FIG. 5, the priority road and the non-priority road intersect each other, and the non-priority road is obliged to stop temporarily. At this intersection, an infrastructure system is installed to prevent encountering collisions.

The system of FIG. 5 is basically the same as the system of FIG. The difference from FIG. 2 is that the measurement range 80
However, it is set to measure vehicles heading to the intersection on the priority road. The road condition detection device 82 (for passing vehicles) is a device such as a camera similar to the detection device of FIG. 2, and detects a vehicle within the measurement range 80.

In the infrastructure control device 56, the transmission information generating section 58 generates transmission information. The transmission information includes passing vehicle information, pedestrian information, and road alignment information. That is, the system is different from the system in FIG. 2 in that information of vehicles passing through the priority road (vehicles passing in front) is transmitted. The passing vehicle information preferably includes the position and speed of the vehicle. The transmission information is transmitted to the vehicle that has entered the communication range 70 through the service-in marker 72.

At the intersection shown in FIG. 5, the vehicle-mounted device provides the driver with the passing vehicle information and the pedestrian information received from the infrastructure. As an example of “provision of passing vehicle information”, an intersection shape is displayed on the display, and passing vehicles approaching from the lateral direction are overlapped and displayed on it. Along with the display, the approach of the vehicle can be notified by voice or notification sound. As an example of the "pedestrian information", the shape of the intersection is displayed on the display, and the pedestrian is displayed on the intersection shape. Along with the display, the approach of a straight ahead vehicle can be notified by voice or notification sound.

These pieces of information may be provided after the vehicle has stopped at the stop line. The information provision may be started before the vehicle reaches the stop line (approaching). Further, it is preferable to provide a vehicle approaching the stop line with information for appropriately stopping at the stop line. It conveys the distance to the stop line and outputs a notification sound or voice indicating the approach.

"Composite Event (Pedestrian-Passing Vehicle)" By the way, a composite event may occur at the intersection shown in FIG. Here, a composite event of pedestrian information and passing vehicle information occurs. This is the case when a pedestrian is crossing in front of the vehicle and the vehicle is approaching along the priority road. When this composite event occurs, the present embodiment provides the following suitable information.

Referring to FIG. 6, in S40, it is determined whether or not provision of pedestrian information is requested, that is, whether or not there is a pedestrian. Here, we mainly consider pedestrians on a pedestrian crossing installed parallel to the stop line.
When S40 is NO, it is determined in S42 whether there is a passing vehicle. If S42 is NO, return to S40,
If S42 is YES, passing vehicle information is provided as usual in S44. On the other hand, even if a pedestrian exists in S40, it is determined in S46 whether a passing vehicle exists.
If S46 is NO, pedestrian information will be provided as usual in S48.

If S46 is YES, it is required to provide both pedestrian information and passing vehicle information. Therefore, S5
0 provides information for both pedestrians and passing vehicles. Here, for example, a pedestrian and a passing vehicle are drawn on the intersection figure.

The information provision in S50 is continued until it is determined in S52 that the pedestrian has crossed the pedestrian crossing, that is, until it is determined that the pedestrian has crossed the front of the vehicle. When a pedestrian crosses, it is determined in S54 whether a passing vehicle still exists, and if there is no passing vehicle, the process returns.

If there is a passing vehicle in S54, it is determined in S56 whether or not the vehicle is about to enter the action of passing the temporary stop line. This action is an action to enter an intersection through a stop line. This determination is made based on, for example, vehicle speed information. When a stopped vehicle starts,
The vehicle speed is not 0, and S56 is determined to be YES. S56 may be determined to be YES when the accelerator is turned on or when the brake is turned off. Of course, it may be determined whether or not these multiple events have occurred. Further, it may be determined from the vehicle position information whether or not the vehicle has crossed the temporary stop line. The vehicle position is obtained by distance integration using the service-in marker as a reference.

If S56 is NO, the process proceeds to S58, in which the passing vehicle information is emphasized and provided. Here, the passing vehicle information may be emphasized as compared with the case where the passing vehicle information is provided alone. For example, blinking display of the passing vehicle image is performed, and voice guidance or notification sound is output.

If S56 is YES, the process proceeds to S60,
Secondary emphasis provision of passing vehicle information is performed. In the second emphasis provision, the degree of emphasis is further increased than that in S58. For example, an alarm sound different from the notification sound of S58 is output and the alarm display is also displayed on the display.

The process of FIG. 6 is continued until the service out marker installed at the end point of the intersection is detected.

FIG. 7 shows a specific example of changing the above-mentioned information providing form. FIG. 7A is before the pedestrian crosses the front of the vehicle, and both the pedestrian and the passing vehicle are displayed on the display. As shown in FIG. 7B, when a pedestrian crosses a pedestrian crossing, the passing vehicle is highlighted by blinking. It is also suitable to change the color of the passing vehicle and increase the size. In FIG. 7B, the presence of a passing vehicle is notified by voice guidance. Furthermore, as shown in FIG. 7C, when the vehicle is about to start, a warning sound is output as secondary emphasis. Although not shown, it is also preferable to display a screen indicating that an alarm has occurred.

As described above, in this embodiment,
When a composite event of pedestrian information and a vehicle passing in front occurs, the time of providing individual information and the form of provision are changed. After the pedestrian crosses in front of the vehicle, the passing vehicle is highlighted. Still, when the vehicle is about to start, further emphasis is given. By providing such information, necessary information can be effectively transmitted and safety can be improved as described above regarding the information provision at the right-turn intersection.

The preferred embodiments of the present invention have been described above. In the present embodiment, "pedestrian-straight ahead vehicle" (right turn intersection) and "pedestrian-passing vehicle (priority road)" (temporary stop) are taken up as complex events. In addition to this, the present invention is similarly applicable in a situation where a composite event of a front side event and a far side event as seen from the vehicle occurs.

In the present invention, when a complex event occurs, the information provision form is changed. Preferably, when the preceding event is over, the event on the other side is highlighted to inform the driver. Secondary emphasis is provided based on the behavior of the vehicle. As a result, information is effectively transmitted to the driver, and HMI (Human Ma
It is possible to improve performance in terms of chine interface).
The target safety of HS can be improved.

Although the present invention is applied to AHS in the present embodiment, the present invention is not limited to this. The present invention may be applied to driving support systems other than AHS. It is also preferable to apply the present invention to a system of another country corresponding to the AHS system of Japan.

<Disclosure of further invention> At a right turn intersection or a temporary stop place, etc.
Two-wheeled vehicles and four-wheeled vehicles may run side by side, and the driver should be more careful when driving than usual. Even in a driving support system such as AHS, it is desirable to effectively call the driver's attention in such a situation. However, in infrastructure systems, when two-wheeled vehicles and four-wheeled vehicles are running side by side,
Sometimes it is not possible to distinguish between the two. For an in-vehicle device that obtains information from the infrastructure system, one vehicle will appear to be running.

In view of this point, in the present invention, when the object information obtained by communication from the road side is separated, the object information is emphasized and displayed. > The objects here are vehicles, pedestrians, obstacles, and the like.

The effects of the present invention will be described. When a two-wheeled vehicle and a four-wheeled vehicle are running side by side, information on one object is sent from the infrastructure system. When the two-wheeled vehicle and the four-wheeled vehicle are separated from each other, the object suddenly separates and two objects appear to appear. At this time, it is possible to call the driver's attention by emphasizing and providing the object information as compared with that before the separation. The emphasis provision may be performed on the screen, or a voice or a notification sound may be used. The present invention is not limited to the combination of a two-wheeled vehicle and a four-wheeled vehicle, but can be applied to any combination of objects such as two-wheeled vehicles, four-wheeled vehicles, pedestrians, pedestrians and obstacles.

[Prevention of non-stop of temporary stop] Here, FIG.
Disclosure of more appropriate information provision at the temporary stop location as shown in. Regarding the AHS counter-heading prevention function, it is assumed that the information of a vehicle passing ahead is provided before the vehicle reaches the stop line. In this case, it is conceivable that the driver knows that the vehicle passing in front does not come, and instead of stopping at the temporary stop line, the driver may run off the stop line.

In consideration of this point, the present invention provides the information of the vehicle passing ahead only when the vehicle stops at the temporary stop line. This avoids the above problems. The driver can stop at the temporary stop line, receive information (vehicle presence or absence, etc.) of a vehicle passing ahead (vehicles on priority roads) from that line, and perform appropriate driving operation by referring to the presented information.
