Description

Detailed Description of the Invention

All the speed limits of general roads, expressways, and general toll roads nationwide are entered in the car navigation storage unit. In addition, we collect actual traffic accident information from the police of prefectures, etc.
And input into the storage unit of the car navigation by dividing into points where light injury accidents and property damage accidents frequently occur / light injury accidents and property damage accidents frequent sections P2. It may be possible to add the latest information to the P1 and P2 and the speed limit information from the outside, or to delete the information of a portion that has become safe due to road improvement or the like. The method of addition and deletion may be either the method of directly connecting an information terminal to one of K, M1 and M2 to add and delete information, or the method of connecting to K via the Internet and radio waves to add and delete information. . Instead of adding and deleting, the information of P1 and P2 and the speed limit may all be exchanged by the above method. The car navigation K is normally set to start up with the screen display and voice function stopped when the engine is started. On the contrary, K is set to end when the engine stops. The activation and termination of K are instructed by M2 by the information from M1. When M2 is not newly added, M1 which also has the function of M2 commands K. The driver can also manually start and stop K, in which case K can use all functions. The warning indicator A of the present invention is also activated by M2 or M1 having the function of M2 when the engine is started. Conversely, when the engine is stopped, M2 or M1, which also has the function of M2, gives an instruction and ends.

While the automobile is running, speed information is calculated from the microcomputer M1 of the automobile and speed limit information of the current position from the car navigation K is calculated by the newly installed microcomputer M2 or M1 which also has the function of M2. If the vehicle is overspeeding, the warning indicator A having one or a plurality of light emitters changes the color / luminance and the issuing form in accordance with the overspeeding to alert the driver. For example, the luminous bodies in the warning indicator A are a1, a2, and a3, and the speed limit is 10
When exceeding km / h, a1 emits red light, 11 km / h
When the speed exceeds 30 km / h or more, a1 and a2 emit red light. When the speed exceeds 31 km / h, a1, a2, and a3 emit red light to alert the driver. The number of light emitters is arbitrary. As the material of the light emitter, any material such as liquid crystal, light emitting plastic, and light emitting diode can be selected.

When an automobile passes through P1 or P2 while running, information from K and M1 is calculated by M1 which also has the function of M2 or M2, and the color, luminous intensity and light emission form are changed by A,
Call attention to the driver. For example, when passing P1, a1, a2, and a3 flash red in front of them. When passing P2, a1, a2, and a3 flash in yellow from this side. When a car passes P1 or P2 because it exceeds the speed limit, a1, a2, and a3 flash red more intensely than usual from that point. The color, luminous intensity, and light emission form can be arbitrarily set.

When the car navigation K is compatible with VICS, when a danger information signal is received from an optical beacon, a radio wave beacon, or an FM multiplex broadcast, calculation is performed by M2 or M1 which also has the function of M2, and the warning indicator A emits light. Change the color, luminosity, and luminescent form of to alert the driver. For example, a1 ・ a
2 ・ a3 blinks red. If the speed limit is exceeded a1 ・ a
2 ・ a3 flashes red more intensely than usual.

The warning indicator A is located at a position where the driver can recognize it without removing his or her line of sight from the front. Approximately 60 degrees above, 75 degrees below, and 100 degrees left and right It should be installed within. However, it is a position where it does not interfere with the driver's front safety confirmation. The warning indicator A is
It has a structure or fixed type that can adjust the position according to the driver's preference. A may be built in above the steering wheel. A
In the case where the speed limit is greatly exceeded, a small motor may be used to automatically move it to a position that is easier for the driver to see.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a warning display device using car navigation.

[0006]

2. Description of the Related Art Conventionally, the driver had to confirm the speed with a speedometer and memorize the accident-prone spot, the accident-prone section and the danger information. Also, if the car navigation calls the driver's attention, the car navigation had to be activated.

[0007]

However, according to the above-mentioned conventional techniques, the driver has to move his or her line of sight from the front to the speedometer to confirm whether it is a safe speed or not, and to move forward again. The driver had to remember intersections and curves where many accidents occurred. The driver did not know the intersections and curves where many accidents occurred in the distance or on unknown roads. Unless VICS-compatible car navigation was activated, it was not possible to know danger information from optical beacons, radio beacons, and FM multiplex broadcasts. In many cases, the driver does not know the speed limit of the road on which he is currently traveling, and it is dangerous because the driver is likely to exceed the speed limit. Therefore, the present invention aims to provide the presence or absence of the speed limit and its extent, the accident-prone point / accident-prone section, and the danger information on the route while using the car navigation while the driver keeps his eyes on the front. And

[0008]

In order to solve the above-mentioned problems, the invention of claim 1 uses a car navigation system to indicate whether or not a speed limit is exceeded and the degree to which the speed limit is exceeded by a warning display having one or a plurality of light emitters. The device is a device that calls attention to the driver. The invention of claim 2 is a warning display device having one or a plurality of light emitters for hazard information on accident-prone spots, accident-prone sections, and routes using a car navigation system to alert the driver. It is a characteristic device. The invention of claim 3 is characterized in that the warning indicator is installed at a position that does not hinder the driver's front safety confirmation and within the visual range of the driver looking ahead.

1 is a block diagram of an embodiment of the present invention.
Shown in. A warning indicator A having a plurality of light emitters is installed near the center of the dashboard of a car. The warning indicator A has light-emitting bodies a1, a2, and a3 inside. The range surrounded by the chain double-dashed line L1 is a human visual field when the driver looks ahead, and the range surrounded by the chain double-dashed line L2 is a range necessary for the driver to confirm the front safety. . A is L1
It is inside and outside L2. The light emitters a1, a2, and a3 in the warning display A emit red light when the speed limit exceeds 10 km / h, and 11 k / h or more and 30 k or more.
When exceeding m / h, a1 and a2 emit red light, 31 km
/ H or more is exceeded, a1, a2, and a3 emit red light to alert the driver. When the overspeed exceeds 51 km / h, a1, a2, and a3 flash more intensely than usual in red. In addition to the above, the excess speed at which the light emitters a1, a2, and a3 operate can be set arbitrarily. When passing P1, a1, a2, and a3 flash red from this side. P2
When passing through, a1, a2, and a3 will flash yellow from this side. When a car passes P1 or P2 because it exceeds the speed limit, a1, a2, and a3 flash red more intensely than usual from that point. When a signal of danger information is received from an optical beacon, radio beacon, or FM multiplex broadcast, a1 ・ a2 ・
a3 blinks red. When a danger information signal is received due to exceeding the speed limit, a1, a2, and a3 flash more intensely than usual in red. In this embodiment, the light emitters a1, a2, and a3 emit red light, and blinks are red and yellow, but the color, luminous intensity, and light emission form can be arbitrarily set. The warning indicator A has a rectangular shape in FIG. 1, but may have another shape such as a square, an ellipse, and a circle. The shape of the light-emitting body is also a rectangle in FIG. 1, but may be another shape such as a square, an ellipse, or a circle.
The warning indicator A may be installed at any location such as built-in in the upper part of the steering wheel, the left and right ends or the lower part of the rearview mirror, the periphery of the windshield, the dashboard, etc. within the above range. A may have a structure in which a small motor can automatically move it to a position that is easier for the driver to see when it is dangerous, such as when the speed limit is significantly exceeded. FIG. 4 illustrates a transmission path of information. M2 receives speed information from M1, speed limit information of traveling points, accident-prone points / accident-prone section information, and danger information on the route from car navigation K, and calculates the color / luminance and light emission form on warning indicator A. Command. In the case of FIG. 5, M1 has the function of M2. Therefore, M2 is not necessary, and the speed limit information of the driving point, accident-prone points and accident-prone section information, and danger information on the route are received from the car navigation K, and the speed information coming into M1 is calculated, and the color and luminous intensity of A are calculated. And command the light emission form.

As another embodiment, FIG. 2 shows a case where the warning indicator A has one light emitter. a1 informs the driver of the area that emits an overspeed with respect to the speed limit. How many km /
In order to make it easy to see if h is exceeded, a scale may be attached adjacent to a1. When passing P1, a from the front
1 All flashes red. When passing P2, the entire a1 blinks yellow from this side. When passing P1 or P2 due to exceeding the speed limit, a1 as a whole flashes red more intensely than before. Optical beacon, electric wave beacon, FM
When a danger information signal is received from a multiplex broadcast, the entire a1 flashes red. When a dangerous information signal is received due to exceeding the speed limit, the entire a1 blinks more intensely than usual in red. The overspeed that can be displayed by a1 can be set arbitrarily, and when the overspeed is exceeded, the entire a1 flashes more intensely than usual in red.
The color, luminous intensity, and light emission form can be arbitrarily set. FIG. 3 shows a case where there are many light emitters of the warning indicator A. It is assumed that there are 10 light emitters a1 to a10. As in FIG. 2, the overspeed is emitted in order from the light emitting body a1 to the speed limit to notify the driver of the overspeed. For example, if the overspeed is within a4, a1 ・ a2 ・ a3 ・ a
4 emits light or a1, a2, a3 emits light and changes the light emitting area of a4 in proportion to the overspeed to notify the driver of the overspeed. As in FIG. 2, a scale may be provided adjacent to the light emitter. The number of light emitters is arbitrary and may be more or less. Similar to the description of FIG. 1, A of FIG. 2 and FIG.
The shapes such as a1, a2, a3, and a4 may be different shapes such as a square, an ellipse, and a circle. In FIG. 3, when the car passes P1, a1 to a10 flash in red from the front. When passing P2, a1 to a10 blink yellow in front of this. When passing P1 or P2 when the speed limit is exceeded, a1 to a10 flash red more intensely than before from that point. When a danger information signal is received from an optical beacon, radio beacon, or FM multiplex broadcast, a1 to a10 blink red. When a danger information signal is received when the speed limit is exceeded, a1 to a10 flash red more intensely than usual.
The overspeed that can be displayed by a1 to a10 can be set arbitrarily, and when the overspeed is exceeded, a1 to a10 flash red more intensely than usual. The color, luminous intensity, and light emission form can be arbitrarily set. The color / luminance, the light emission form, and the displayable excess speed can be set either by the automobile manufacturer in advance or by the driver using K to set the preference. Note that only one of the settings may be set. The parts of the car that enter the L1 differ depending on the type of car. When the driver's seat is on the right side, L2 is not symmetrical and is widely flattened to the left. On the contrary, when the driver's seat is on the left, it is wide and flat on the right. The present invention may be mounted on a motorcycle. In that case, the structure A of the motorcycle may be attached to the outside of L1. Another device may be connected to the present invention and other information may be displayed on A by changing the color / luminance and the light emission form. The present invention starts when the engine starts and ends when the engine stops, but may start when the driver turns the key and the electric system of the automobile turns on, and conversely ends when the electric system turns off. . Further, the present invention may be started and ended at any time other than the above. Electric vehicles, fuel cell vehicles, etc. can also be set to start and end at any time.
