BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information display device, and more particularly to a vehicle information display device for visually presenting driving assistance information to a driver of a vehicle.

[0002]

2. Description of the Related Art Navigation systems have been developed to assist driving of vehicles and are used in many vehicles. Generally, a navigation system is provided as a separate product from a vehicle. For this reason, the driver often has to move his / her line of sight in order to check the information provided on the display device of the navigation system while driving. Further, there is a case where the information cannot be confirmed at a glance because the amount of provided information is large.

There is also known a system for monitoring the front of a vehicle and displaying it as an image in order to assist driving in poor visibility such as during rain or fog. For example, a navigation system described in Japanese Patent Application Laid-Open No. 1-219883 is known.

According to this navigation system,
The shape line of the road such as the outline of the road is superimposed on the scene ahead and displayed head-up. For this reason, in the case of poor visibility such as during rainfall at night, the driver can visually observe the clear road shape line head-up displayed by superimposing the shape line on the unclear forward scene. There are great advantages. Further, by synthesizing a navigation system guidance image such as map information, it is possible to reduce the driver's line of sight even when collating with the map.

Further, the vehicle driving support system described in Japanese Patent Application Laid-Open No. H8-253059 also includes a means for photographing a scene in front of the vehicle, so that the outline of the road and other shape lines are projected on the head-up display, It forms an image of the scene ahead of the vehicle and provides the driver with a clear view even at night or in fog.

However, in the prior art, since a guidance image of a navigation system such as an arrow is displayed on a display, a high-speed operation CPU for digitization and a memory having a large data capacity are required.

The display is a two-dimensional display,
Since the scene in front of the vehicle is a three-dimensional space, high-precision image synthesis requires complicated calculations, and is therefore expensive.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A vehicle information display device according to the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a block diagram showing the configuration of the information display device according to the first embodiment of the present invention. Referring to FIG. 1, an information display device includes an object detection unit (means) 1, a road planning unit (means) 2, a control unit 3, a display unit 4, a vehicle speed sensor 5, a steering angle sensor 6, a headlight / vehicle. And a width light 7. The control unit 3 includes a calculation unit (means) 3-1, a display color control unit 3-2, and a display order control unit 3-3.

The object detecting section 1 detects an object in front of the vehicle. For example, the object detection unit 1 includes one of an infrared radar, a millimeter-wave radar, a high-sensitivity camera, and an infrared camera. Data of the detected object is output to the control unit 3. In this specification, the term "object" may include a pedestrian, a person riding a bicycle, and a traveling vehicle, together with an object such as a fixed installation object.

The road guidance unit 2 includes, for example, a navigation
It is realized by the system. The road guidance unit 2 detects the current position of the vehicle based on information provided from the outside, and outputs the current position to the control unit 3.

The display section 4 is composed of a plurality of light emitters arranged on an instrument panel near the windshield. The luminous bodies are arranged in rows from the driver's seat, as shown in FIG. Alternatively, the light emitters may be arranged in a matrix. In this case, a light emitter in a designated direction, for example, a radial direction is selected from the light emitters in the matrix, and emits light.

The vehicle speed sensor 5 detects the current running speed of the vehicle and outputs it to the control unit 3.

The steering angle sensor 6 detects a change in the running direction of the vehicle when the steering wheel is turned, for example, to turn right or left, and outputs the change to the control unit 3.

The controller 3 calculates the relative position and relative speed of the object from the detection result of the object detector 1. The relative speed is calculated as a vector, and the relative speed and the relative moving direction can be determined based on the relative speed. The control unit 3 generates object information based on the calculation result, and controls a display method of the display unit 4 so as to indicate an object to be noted.

The control unit 3 also has map information built therein and stores information on a taxiway input from an input device (not shown). When the information indicating the current position of the vehicle is supplied from the road guide unit 2, the control unit 3 controls the display method of the display unit 4 so as to indicate the guidance route to be driven.

Further, the control section 3 can detect the lighting state of the headlight / width lamp 7 and controls the luminance of the luminous body.

Since the object detecting section 1 continuously detects an object, the control section 3 changes the illuminant group of the display section 4 based on the object information while changing the illuminant group as a whole or The display unit is controlled based on the object information so as to be turned on partially and continuously or intermittently.

More specifically, the arithmetic unit 3-1 of the control unit 3
Calculates the relative position and relative speed of the object according to the detection result of the object detection unit 1, and calculates at least one of them.
Generate object information including Here, the object information indicates the relative position or movement (magnitude of relative speed, relative moving direction) of the object with respect to the vehicle, and, if necessary, the absolute position of the object on the earth coordinates, or Exercise shall be included.

When the object detection unit 1 includes an infrared radar or a millimeter wave radar, the relative position of an object ahead of the vehicle can be known. The relative speed between the object and the vehicle is determined from the change in the relative position of the object in front of the vehicle. For example, assuming that the speed of the object is v and the speed of the vehicle is V, the relative speed between the object and the vehicle is represented by (v−V).

When the relative speed between the object and the vehicle is smaller than 0, the object is traveling relatively closer to the vehicle. When the relative speed between the object and the vehicle is greater than 0, the object is traveling relatively away from the vehicle.

When the object detection unit 1 includes an infrared radar or a millimeter wave radar, an object outside the traveling road may be detected. However, a solution is provided by using a plurality of radars and increasing the directivity of each radar. can do. Further, since the speed and the moving direction of the vehicle can be known from the vehicle speed sensor 5 and the steering angle sensor 6, the speed of the object in front of the vehicle can be obtained. If the absolute value of the relative speed between the vehicle and the object is equal to the magnitude of the vehicle speed and the direction is opposite, it can be determined that the object is fixed.

The object detection section 1 may include a high-sensitivity camera or an infrared camera. In this case, the calculation unit 3-1 extracts an image of the object in the road from the image information from the object detection unit 1, and determines the magnitude of the relative speed between the vehicle and the object based on the rate of change in the size of the extracted image area. The relative movement direction can be determined. Since the speed of the vehicle is given as a vector value from the vehicle speed sensor 5 and the steering angle sensor 6, the absolute speed of the object can be determined.

The calculation unit 3-1 stores map information and stores information on a taxiway input from an input device (not shown). When the information indicating the current position of the vehicle is supplied from the road guide unit 2, the calculation unit 3-1 determines a guideway to be driven and outputs guideway information. Therefore, in this case, the road guidance unit 2 and the calculation unit 3-1 constitute a navigation system.

The display color control section 3-2 and display order control section 3-3 of the control section 3 function as light emission control means.

The display color control unit 3-2 determines each illuminant in the illuminant array (group) based on the object information from the arithmetic unit 3-1.
The display unit 4 is controlled so as to emit light with a light emission color determined based on the object information. For example, when a vehicle is approaching a pedestrian from behind a pedestrian, or when a pedestrian or the like is going to cross a road on which the vehicle is traveling, red or the like is employed to draw special attention. . Otherwise, for example, yellow is used.

The display color control unit 3-2 includes an arithmetic unit 3-
The light emission color is determined based on the guideway information from No. 1. For example, the display unit 4 displays a yellow taxiway when the new taxiway is ahead of a predetermined distance from the current position, and displays a red taxilight when the new taxiway is within a predetermined distance.
Control.

The display order control unit 3-3 is provided with a calculation unit 3
The lighting timing of each light emitter in the light emitter row is determined based on the object information from -1. This makes it possible for the light emitters of the light emitter row to emit light in whole or in part. Further, the display unit 4 is controlled so that the lighting unit flows so as to indicate the moving direction of the object by shifting the lighting timing of each light emitting body in the light emitting body array based on the moving direction of the object.

Further, the display order control unit 3-3 controls the display unit 4 so as to turn off all the light emitters when the vehicle has passed the object.

Further, the display order control unit 3-3 includes the operation unit 3
The display unit 4 is controlled so as to instruct a new taxiway while changing the light emitting element array that emits light based on the taxiway information from -1 and the traveling direction change information from the steering angle sensor 6, and the vehicle proceeds on the new taxiway. After that, the display state is maintained for a predetermined time.
After that, the display unit 4 is controlled so as to turn off the light emitting body row.

Next, the operation of the vehicle information display device of the present invention will be described.

FIG. 2 is a top view of the front portion of the vehicle. Instrument panel 10 near windshield 11
A plurality of luminous bodies are provided as a display unit 4 on the upper part of the display. Here, the LED is embedded. Each of these light emitters forms a row, and is arranged radially with the driver's seat at the center. However, the LEDs may be arranged in a matrix, and the radial portions thereof may be turned on.

As shown in FIG. 3, for example, the road guide 2
When a right turn at an intersection is guided for a new taxiway by the arithmetic unit 3-1 of the control unit 3 and exists on a straight line connecting the entrance direction of the road (corresponding to the center of the road width) and the driver's seat. The display order control unit 3-3 of the control unit 3 controls the display unit 4 so that the illuminating light emitting column turns on. At this time, when the new taxiway is farther than the predetermined distance from the vehicle, the display color control unit 3-2 causes the display unit 4 to display the light emitter row in yellow.
Control.

Since this guidance operation is a vehicle speed response operation, the display order control unit 3-3 controls the display unit 4 so that as the approaching intersection approaches, the adjacent light emitting element row lights up as if a fan were opened. . At this time, in order to avoid the driver's confusion, only one row of light emitters is turned on. When the new taxiway is within a predetermined distance from the vehicle, the display color control unit 3-2 controls the display unit 4 so that the light emitter row is displayed in red. Thereby, the driver can know that a new taxiway is near.

When the start of a right turn of the vehicle is detected from the traveling direction change information from the steering angle sensor 6,
The display order control unit 3-3 controls the display unit 4 so that the light emitter array in the straight ahead direction of the vehicle is turned on as if the fan is closed.
Control. Also, immediately after the bend, the light emitter row is not turned off. For a while (in this case, for one second), the row of light emitters in the straight ahead direction of the vehicle continues to be illuminated to inform the driver that the road has been guided correctly. This allows the driver
You can have a sense of security. After that, the display order control unit 3
-3 controls the display unit 4 so as to turn off all the light emitter rows.

The purpose of the information display device of the present invention is to inform the driver of the direction of the object to be viewed, so that the information display device is also used for purposes other than navigation.

For example, in a situation of poor visibility such as rainfall at night, as described in Japanese Patent Application Laid-Open No. 1-218983, the driver may change the shape line of the clear road on which the head-up display is made. I look over the sight ahead. Also in the present invention, in addition to the navigation system guidance information, the detection result of the object detection unit 1 by the infrared radar or the millimeter wave radar, or the image taken by the high-sensitivity camera or the infrared camera during nighttime or running in fog, is processed. By extracting following vehicles, oncoming vehicles, pedestrians, and bicycles,
The direction can be indicated by the light emitter row.

As shown in FIG. 4, the driver can be aware of the direction in which the object is located, even if the object to be viewed is beyond the range of the headlight of the vehicle. In this case, the display order control unit 3-3 controls the display unit 4 to turn off the light immediately after passing a pedestrian or the like. The driver does not follow the visual target even after passing through, and the driver's attention is easily directed to the front of the vehicle.

Further, this display device can also inform the driver of the movement of the object by the color of the luminous body and the lighting order. The object detection unit 1 detects an object and outputs a detection result to the calculation unit 3-1 of the control unit 3. The calculation unit 3-1 calculates the relative position and the relative speed of the object according to the detection result of the object detection unit 1, and generates object information including at least one of them.

The calculation unit 3-1 determines the relative position of the object ahead of the vehicle from the detection result of the object detection unit 1. The relative movement between the object and the vehicle is determined from the change in the relative position of the object in front of the vehicle.

For an object coming to the host vehicle, the display order control section 3-3 controls the display section 4 so that the lighting section of the light emitting element line sequentially flows from the front of the vehicle to the driver side. . At this time, the control unit 3 checks the lighting state of the headlight / vehicle width light 7 and drives the vehicle width light to be turned on when the width light is not lit.

For an object traveling in a direction relatively distant from the host vehicle, the display order control unit 3-3 displays the light so that the light emitting units of the light emitting body array flow sequentially from the driver side toward the front of the vehicle. The unit 4 is controlled. At this time, the control unit 3 confirms the lighting state of the headlight / vehicle width light 7 and, when the headlight is directed downward and the object is not in the lighting range, changes the headlight upward and extends the lighting range. To drive the headlights.

The blinking flow may be variable depending on the speed of approach to the object. For example, when the object is moving at a speed higher than the walking speed (6 km / h) such as jogging or bicycle, the display order control unit 3-3 causes the lighting unit to flow faster based on the walking speed as the reference speed. To control the display unit 4.

When the object is a pedestrian or a bicycle and the object is traveling in the opposite direction to the own vehicle, it is expected that they are looking at the own vehicle. For this reason, the display color control unit 3-2 controls the display unit 4 so that the emission color becomes yellow.

On the other hand, when a pedestrian or a bicycle is traveling in the same direction as the host vehicle, the host vehicle approaches from behind them, and he often does not notice the host vehicle. For this reason, the display color control unit 3-2 controls the display unit 4 so that the emission color is red so as to call the driver more attention.

If the vehicle is stationary on the road, is crossing the road, or is crossing the road, the display color control unit 3-2 controls the display unit 4 so that the emission color becomes red. I do.

Further, both the direction guidance of the visual target based on the detection result of the object detection unit 1 and the road guidance based on the detection result of the road guidance unit 2 may be performed at the same time. For example, in the case of navigation system guidance by the road guide unit 2, the display color control unit 3-2 controls the display unit 4 so that the light emitting element array is displayed in green, and the object detection unit 1 detects the pedestrian. In this case, the display color control unit 3-2 may control the display unit 4 so that the light emitting element rows are displayed in red or yellow. In this case, the difference in information can be clearly distinguished. Even if both display directions are the same, it is possible to inform the driver at the same time.

Further, during normal driving, the control unit 3 operates in the direction guidance mode for guiding the direction of the visual target based on the detection result of the object detection unit 1, and when the vehicle approaches a new guidance path,
The mode may be switched so as to operate in a road guidance mode for performing road guidance based on the detection result of the road guidance unit 2.

When each illuminant of the illuminant array is composed of a pair of LEDs, one of the LED arrays is connected to the object detecting section 1.
Used to guide the direction of the visual target based on the detection result of
The other LED string may be used for road guidance based on the detection result of the road guidance unit 2. In this case, the above control can be performed more easily.

Next, an information display device according to a second embodiment of the present invention will be described. In the first embodiment, the display unit 4
Although a plurality of light emitter rows are installed on the upper surface of the instrument panel 10, as shown in FIG. 5, for example, a backlight type liquid crystal display device is used in the second embodiment. The display states shown in FIGS. 6 and 7 correspond to the display states of FIGS. 3 and 4 in the first embodiment.

In the information display device according to the second embodiment,
Instead of the light emitter array, an instruction mark such as an arrow is displayed on the liquid crystal display device. Further, a pixel group of the liquid crystal display device corresponds to each light emitter in the light emitter row. In this way, the indication mark can indicate a viewing target and can also indicate a new guidance route. The display color of the instruction mark is controlled by the display color control unit 3-2, and the lighting state of the pixel group in the instruction mark is controlled by the display order control unit 3-3, as in the first embodiment. Therefore, detailed description is omitted.
