PU, ROM with built-in program for performing predetermined arithmetic processing, place name data, etc., RAM for registering data of each transit point, etc., and display of the result of predetermined arithmetic processing by CPU through LCD driver Display screen 2 and GPS (GlobalPositi
oning System).

FIG. 2 shows a main part of a navigation device according to the above-described system. In the present embodiment, the main body 1 of the navigation device is of a liquid crystal display type installed near the center of a steering wheel of a motorcycle. It is formed integrally with the meter, and a display section (display) of the meter for displaying the vehicle speed (speedometer), mileage (odometer and trip meter), time (digital clock), etc. as a display screen 2 of the apparatus main body 1. Screen 2B) and a navigation display unit (display screen 2A) for displaying the current position and the distance and direction to the destination (the next stopover) are displayed independently as display screens 2A and 2B of substantially the same size. And are arranged adjacent to each other.

The relationship between the main unit 1 of the navigation device and the meter is implemented by adjoining the main unit 1 and the meter as separate units so that the respective display screens are arranged close to each other. When the main body 1 and the meter are integrally formed, the display screen of the main body 1 and the display screen of the meter can be shared by one display screen, and the display section of the meter and the display of the navigation are provided. It is also possible to carry out by integrating the parts.

The apparatus main body 1 has a data input key 3 for the rider to manually input the data of each stopover directly to the apparatus main body 1 and a mode switching button 4 for switching the display mode of the display screen 2. Are installed at the periphery of the display screen 2 on the upper surface of the apparatus main body 1 and input data by infrared communication from a separate apparatus such as a simple remote controller or a personal computer.
An infrared input / output window 5 for outputting information stored in the main body 1 by infrared communication is formed on a side surface of the apparatus main body 1.

As shown in FIG. 1, a vehicle speed sensor and a terrestrial magnetism sensor installed at appropriate places of a vehicle are connected to such an apparatus main body 1, respectively. A GPS antenna is connected to a receiver (detecting the latitude and longitude of the current position by a received radio wave from a satellite) in the apparatus main body 1,
Thus, the speed of the vehicle detected by the vehicle speed sensor, the direction of the vehicle detected by the geomagnetic sensor, the current position of the vehicle detected by the GPS receiver, and the like are each used as information for guidance and guidance. Of the CPU.

Further, as a means for manually transmitting an input signal to the CPU of the apparatus main body at the intention of the rider, a waypoint switching button 6 and a memory button 7 are connected to the apparatus main body 1, respectively. As means for automatically sending an input signal to the CPU of the apparatus main body 1, a neutral switch and a side stand switch are respectively connected, and a signal for calling a rider attention by an output signal from the CPU of the apparatus main body 1. As a means for issuing a warning, a transmitting section 8 of a warning means by vibration is connected to the apparatus main body 1, and as one of various display lamps provided on the upper surface of the apparatus main body 1 as shown in FIG. A closing lamp 13 that blinks at times is provided.

The data input / output structure according to the present embodiment will be described below, together with the description of various functions provided in the navigation device of the present embodiment configured as described above.

First, prior to using the navigation device, when a route is set by a map book or the like, an appropriate branch point in the route is determined as a transit point, and the latitude and longitude of each transit point are determined. In this embodiment, the data of each transit point (branch point) is stored in the RAM of the main body 1 of the main body 1 in such a manner that the position of each transit point is represented by latitude and longitude. At the same time as input (number input), the direction of travel at each stopover is input as an absolute azimuth (8 divisions) (arrow input), thereby registering as a list of the order of the route.

In this case, the input method can be directly input by operating the data input key 3. In this embodiment, however, a list of data of each transit point is prepared in advance by the personal computer using the personal computer map software. By preparing a table and transferring it in a batch by infrared communication through an infrared input / output window 5 opened in the main body 1 of the navigation device, a list of data at each transit point is stored in the main body 1 of the device. It is stored in RAM.

With regard to such data input by batch transfer of personal computers, recently, personal computers have become popular and have become more sophisticated, and since many map softwares for personal computers have been circulating, transfer using personal computer map software has been carried out. By registering the transit point list at once after creating the possible data, the complexity of the registration work can be eliminated and the data can be managed by a personal computer. The advantage is that you can build your own library for the path consisting of

For map software for personal computers,
For each branch point on the road, in addition to the latitude and longitude, if there is one in which the direction of each road extending from the branch point is registered with an arrow of an absolute azimuth divided into eight, Using map software, you can easily create a list of data for each waypoint by simply selecting the arrow in the direction that will become the route at the branch point on the route and clicking with the mouse. The remaining arrows that have not been used can be registered as reference information (directions of other roads at each transit point) in the data list of each transit point.

By the way, the input of the data of each transit point to the apparatus main body 1 is not limited to the batch transfer input by the personal computer, but can also be input by infrared communication with a simple remote controller, or directly by operating the data input key 3. A list of data of each transit point can be created and input on the display screen 2 of the apparatus body 1.

That is, when data of each transit point is directly input by the data input key 3, first, the display of the display screen 2 of the apparatus main body 1 is switched by the mode switching button 4 as shown in FIG. After switching to the land registration mode (a screen displaying a list of data of each transit point), the data input key 3 is operated to display the latitude and longitude of each transit point on the screen of the transit point registration mode. By entering the absolute direction of travel at the stopover,
After a list of data of each transit point is created, it is stored in the RAM of the apparatus main body 1.

When the mode switching button 4 used at that time is pressed, the display on the display screen 2 is changed to the driving mode as shown in FIGS. 4 (A) to 4 (C).
This is for switching between the latitude / longitude display mode and the transit point registration mode, so that when the vehicle is traveling, the display screen 2 is automatically displayed in the traveling mode. When the vehicle is stopped, the display mode of the display screen 2 can be manually switched to the latitude / longitude display mode or the waypoint registration mode.

As for the display screen 2 of the navigation device capable of switching the screen as described above, in this embodiment,
It is composed of a display screen 2A for navigation and a display screen 2B for meter, which are formed independently of each other and have substantially the same size, and are arranged adjacent to each other. As shown in FIG. 4 (A), a navigation display indicating the distance and direction to the current location and the next stopover (Point) is displayed on the display screen 2A, and the vehicle speed (speedometer) and the mileage (odometer and twin trip meter) are displayed. The meter display such as the time and the time (digital clock) is displayed on the display screen 2B.

In the latitude / longitude display mode, a navigation display indicating the current position and the distance and direction to the next stopover (Point) is displayed on the display screen 2A, and the display screen 2B displays the vehicle speed. The latitude and longitude of the current position are displayed as switching and navigation information. In the transit point registration mode, the display screen 2A displays the latitude and longitude on a list of input contents for each transit point and the display screen 2B. Indicates the absolute direction and the memo field.

Since the display of the latitude / longitude data on the display screen 2B is unnecessary except when searching for the current location on a map, the latitude / longitude display is performed only when the vehicle is stopped, without manual operation using the mode switching button 4 when the vehicle is stopped. The mode may be automatically displayed, and the display design is such that the vehicle speed display is eliminated in the latitude / longitude display mode shown in FIG. May be displayed with the latitude and longitude.

In this embodiment, both display screens 2
In the latitude / longitude display mode in which the navigation information is displayed in A and 2B, the information having high importance in the navigation information, that is, the distance and direction to the next stopover (and the turn direction of the vehicle) are used for navigation. Is displayed on the display screen 2A, and information of low importance, that is, the latitude and longitude of the current position is displayed on the display screen 2B for the meter.

The display of the transit point registration mode will be described later (change, deletion,
As described in the description of the additional functions), even if the vehicle is stopped, if the predetermined conditions are not met, even if the mode switching button is operated, the mode is not switched to the transit point registration mode. If you start running in the registration mode, it will automatically change to the running mode immediately.

Now, as described above, the RA of the
A description will be given of the operating state of the navigation device in which a list of data of each transit point is registered in M. When the motorcycle is heading to the destination (the next transit point), the GPS signal from the satellite is always used. GP based on reception of radio waves
The latitude and longitude of the current position are detected by the receiver for S and input to the apparatus main body 1. In the apparatus main body 1, based on the detection data of the current position and the data of each transit point stored in the RAM. According to a program stored in the ROM, predetermined arithmetic processing is performed by the CPU, and the result is displayed on the display screen 2.

The navigation display displayed on the display screen 2 of the apparatus main body 1 while the vehicle is running is as follows.
As shown in FIG. 2 or FIG. 4 (A), in the driving mode, while traveling at a point far from the next stopover on the display screen 2A, the place name near the current position is displayed by the place name data stored in the ROM. And the distance and direction to the next stopover are displayed.

When the vehicle approaches the next transit point, the direction of the vehicle body at that time is detected by a geomagnetic sensor and compared with the traveling direction. If the vehicle direction is different from the traveling direction, it is input in advance. By correcting the absolute azimuth of the traveling direction at the next transit point to determine the turn direction of the vehicle at the next transit point, as shown in FIG. 3 and FIG. Is automatically displayed on the display screen 2A so as to indicate the turn direction of the vehicle at the time.

In this embodiment, FIGS. 3 and 4
As shown in (A) and (B), in the driving mode and the latitude / longitude display mode, the place name near the current location, the distance to the next stopover, and the direction to the next stopover are always displayed on the display screen 2A. However, in FIG. 5, only the distance to the next stop and the turn direction of the vehicle are shown, and the others are omitted.

That is, in the display on the display screen 2A in the traveling mode in which the vehicle is traveling, when the vehicle is away from the next stopover, the place name near the current position, the distance to the next stopover, and the direction to the next stopover are shown. Is just displayed,
When the vehicle approaches the next stopover (junction point), the turn direction of the vehicle is additionally displayed on the display screen 2A, so that the close lamp 13 blinks and the rider can be visually noticed. At the stopover point, the vehicle travels in accordance with the instructed turn direction, so that the vehicle is guided and guided along a preset route.

In particular, in the present embodiment, the data of each transit point is obtained by inputting the traveling direction at the transit point in the absolute direction, and the data in the absolute direction is actually used when entering the transit point. Since the turning direction of the vehicle is determined by correcting the direction of the vehicle body (data detected by the geomagnetic sensor), even if there are a plurality of approach courses to the via point from different directions, or the wrong way point Even if the vehicle returns after having gone too far, it will always be indicated by the arrow in the correct turn direction when viewed from the running vehicle, regardless of the approach course to the stopover.

As described above, map software is used in which the directions of the roads extending from the branch point are all registered by the arrows of the absolute azimuth divided into eight, and the other roads at each waypoint are used. If the direction is registered as an arrow in the list of data of each transit point as reference information, when the turn direction of the vehicle is displayed, as shown in parentheses on the right side of FIG. In addition to the direction display, the branching state of another road can be displayed together.

By the way, when approaching a junction (transit point) where guidance is required as described above, the turn direction of the vehicle is displayed on the display screen 2A. However, in the case of a motorcycle, the display screen is not displayed during traveling. Since it is not possible to look closely, it may not be noticed only by the display on the screen, and therefore, it is necessary to call attention by a warning other than the screen display.

For this reason, in this embodiment, when approaching each stopover, the close lamp 13 flashes, and the vibration of the vibrator mounted in the helmet of the rider causes the rider to experience the junction point (stoppoint). Let's recognize the proximity of. (A voice guide such as that found in a car navigation system cannot be heard due to wind noise, especially at high speeds.)

As shown in FIG. 7, the warning means using such a vibrating body is provided by a radio wave output from the transmitting section 8 based on an output signal from the apparatus main body 1 in the vicinity of a stopover.
The vibrating body 9 mounted in the helmet is wirelessly controlled via the receiving unit 10 mounted on the surface of the helmet, whereby the vehicle is moved to a branch point (transit point) where guidance is required. Approaching, the warning by the vibration of the vibrating body 9 prompts the user to view the display screen 2A.
The warning start timing is controlled so as to be variable according to the vehicle speed.

The warning means is not only a reminder to the display screen as described above, but also allows the rider to identify the difference in the warning vibration by changing the vibration frequency, and arranges the vibrating body on both the left and right sides. By activating one of them, it is possible to instruct the turn direction, and instead of the vibrating body, it is also possible to use a high-frequency sound or light for hearing or visual warning.

As described above, the display screen 2A is watched by the warning and the vehicle is made to proceed in the turn direction indicated by the arrow, so that after passing through one transit point, the vehicle is further moved to the next transit point. However, in this embodiment, at this time, the vehicle is not automatically switched to the guidance for the next transit point (a transit point one point ahead of the transit point that has passed), and When the rider manually presses the stopover switching button 6 after confirming the passage, the guidance is switched to the guidance for the next stopover.

By such manual switching with the waypoint switching button 6, the display of the turn direction of the vehicle disappears, and the display screen 2A again displays the place name near the current position and the next name as shown in FIG. Only the distance to the stopover and the direction to the next stopover will be displayed.

As shown in FIG. 6, the waypoint switching button 6 for performing such manual operation by the rider can be operated without releasing the handle from the steering wheel. It is located near the grip part of the steering wheel (handle switch part), and as long as a list of transit points data is registered in advance in the transit order, the rider can press the transit point switching button 6 after passing the transit point. , Guidance of the next stopover can be started.

Regarding the switching of the guidance to the next transit point, there is a system in which a list of data of transit points is stored in a simple navigation device for automobiles. Later, you need to reset the settings to select the next stop.

In contrast to the above-described switching to the next stopover by the rider's manual operation, it is conceivable to automatically switch according to the order of the list of the stopover data when the vehicle passes through the stopover. However, in this case, for example, if the user deliberately bypasses a certain transit point, guidance for the subsequent transit point will not be possible at all, or even if the user passes over the transit point by mistake, it will not be immediately recognized ( If you do not switch automatically, you will know immediately when you pass through a stopover, because the direction indicator arrow will be opposite to the direction of travel.) There is a problem that the guidance to the next transit point has already been started and the guidance at the transit point is not performed.

By the way, in the navigation apparatus of the present embodiment, when the vehicle stops, the data of each pre-registered waypoint is changed, deleted, or added in the middle of a preset route. Is possible.

That is, as in the case of direct input at the time of data registration, the display of the display screen 2 is switched from the driving mode or the latitude / longitude display mode to the transit point registration mode by operating the mode switching button 4, and FIG. As shown in C),
By operating the data input key 3 with the list of input contents for each transit point displayed on the display screen 2, the data of each transit point displayed is changed, deleted, or added. For example, it can be re-registered in the RAM of the apparatus main body 1.

In this embodiment, as shown in FIG. 2, the trip meter is a switchable twin trip meter (A display and B display). / B switching button 11 and reset button 12 are provided, and when the display screen 2 is switched to the transit point registration mode by the mode switching button 4, as shown in FIG. The / B switch button 11 and the reset button 12 are used as operation buttons for changing or deleting each data shown in the displayed data list of each waypoint.

However, with regard to such change, addition or deletion of the waypoint data, in the present embodiment, the motorcycle must not be released from the steering wheel at the time of traveling, so that it cannot be operated at the time of traveling. Not only that, even if the vehicle is stopped, make sure that certain conditions are not met before entering the transit point registration mode.
In the waypoint registration mode, the display at the time of running (running mode) is automatically changed as soon as the vehicle starts running.

The conditions for switching to the transit point registration mode include, for example, three conditions: the vehicle speed is 0 km / h, the driving state is neutral (detected by the neutral switch), and the mode switching button is ON. It is conceivable that the switching can be performed only when the conditions are met, or that the switching can be performed only when the four conditions are met by adding a condition that the side stand is ON (detected by the side stand switch).

Further, in the navigation device of the present embodiment, it is possible to easily register a point to be stored (a sightseeing spot, a branch road, or the like) in the middle of a preset route even during traveling. ing.

That is, as shown in FIG. 6, a memory button 7 is disposed in the vicinity of the handle grip (handle switch portion) of the vehicle together with the waypoint switching button 6, and the rider presses the memory button 7. At that point,
The position can be input to the apparatus main body 1 as memory data in latitude and longitude, so that a passing point (sightseeing spot, branch road, etc.) to be recorded can be recorded without releasing the handle from the steering wheel. With a single touch, for example, a list of memory data (latitude / longitude data) as shown in FIG. 8A can be registered in the RAM of the apparatus main body 1.

In this embodiment, by the above operation, as shown in FIG. 8A, at the same time, the place name of the place is stored in the memo of the memory data list according to the place name data stored in the ROM. The memo column is automatically registered in the column, but this memo column can be changed later by the user, for example, as shown in FIG.

Incidentally, the navigation device of the automobile includes:
There are systems that can register a route in the current location registration mode. However, in such a system, the screen operation is complicated and it is difficult to register while traveling. In the present embodiment, the route is stored during traveling. By operating the memory button 7 of the steering wheel switch unit at a desired point, the latitude and longitude of the position can be easily registered as memory data with one touch.

Further, in the navigation device of the present embodiment, the traveling locus is simply stored in a memory as shown in FIG. 9 and the memory data is read out later to determine or display the traveling locus. Furthermore, for example, by linking the time with a digital clock of the meter and storing the time at the same time, it becomes possible to calculate the average traveling speed and the like later.

That is, when the map data (CD-ROM) that shows the points actually traveled on a map is not used, a detour may be made between each transit point or a plurality of detours may be made between the transit points. If there is a road, it is not possible to determine later on which road the vehicle has traveled. In the present embodiment, for example, the system shown in FIG.
(A) As shown in FIG. 10 (B), a passing point is periodically time stamped by a timer and its latitude and longitude data is stored in memory, or as shown in FIG. 7 to store latitude / longitude data (memory can be saved compared to storing it periodically with a timer), and then display memory data and map books (latitude / longitude descriptions) To determine the traveling locus, or to display the traveling locus by downloading memory data to a personal computer and linking it with map software.

It is to be noted that even when the vehicle travels freely without setting a route in advance, it is possible to determine or display the traveling locus later by storing the memory data as described above. It is also possible to calculate the average running speed and the like from such memory data.

Further, in the navigation device of the present embodiment, each of the transit points is transmitted by infrared communication through the infrared input / output window 5 so that the memory data and the transit point data as described above can be downloaded. In addition to the input for registering the data, the registered data and the memory data collected by the memory button 7 can be output from the apparatus main body 1.

That is, in this embodiment, the infrared communication through the infrared input / output window 5 of the apparatus main body 1 allows the mutual communication between the apparatus main body 1 and the auxiliary input device (such as a personal computer) or between the apparatus main bodies 1. In order to effectively use such infrared communication, the infrared input / output window 5 for the infrared communication is provided with a vehicle, as shown in FIG. It is provided on the side surface of the apparatus main body 1 so as to be lateral to the traveling direction, so that when exchanging data between vehicles, the vehicles can be arranged side by side.

When data is exchanged between vehicles, the distance between the meter units (main body 1 of the navigation device) of each vehicle can be reduced by moving the vehicles closer to each other in the passing direction. Infrared output can be used effectively, in which case an infrared input / output window is provided especially on the left side so that the rider does not need to support the vehicle, as shown in FIGS. 11 (A) and 11 (B). Thus, it is desirable from the relationship between the position of the side stand and the position where the rider stands. In addition, by providing two infrared input / output windows on the left and right, communication can be performed side by side with the side stand upright, as shown in FIGS.

According to the data input / output structure in the navigation device of the present embodiment as described above, the data of each stopover is registered by infrared communication through the infrared input / output window 5 of the device body 1. In addition to inputting, the registered data and data such as memory data collected by the memory button 7 can be output from the apparatus main body 1, so that data can be transferred between the apparatus main body 1 and an auxiliary input device (a personal computer or the like). In addition to being able to exchange data, it is possible to directly exchange data between the main bodies 1 of the navigation devices mounted on each of the two vehicles on the way without passing through other devices. .

When the data of each transit point is set based on the map data of the CD-ROM, the registered data of each transit point is output from the apparatus main body 1 and the same navigation apparatus of another vehicle is output. Even if the data is input to the apparatus main body 1, if the other party does not have the same map data, the information is not immediately useful as guidance information, but in this embodiment,
Since the registration data of each transit point is entered in the latitude and longitude and the absolute direction without using the map data of the CD-ROM, the registration data of each transit point is sent to the same navigation device of another vehicle. In this case, the other party can immediately use the information as guidance information.

In this embodiment, since the navigation device is mounted on a motorcycle, if the connector of the device main body 1 for inputting and outputting data is of a contact type using a connection cable, the relevant portion is automatically connected. Although there is a concern about water and dust peculiar to the motorcycle, according to the infrared communication through the infrared input / output window 5, the connector can be made non-contact, so that such a concern is released.

Further, in the present embodiment, in the navigation device mounted on the motorcycle, the infrared input / output window 5 for performing the infrared communication is arranged so that the infrared input / output window 5 is lateral to the traveling direction of the vehicle. , The infrared input / output window 5 can be prevented from being exposed to wind and rain from the front, and vehicles can be arranged side by side when exchanging data between vehicles. .

That is, by bringing the two vehicles closer to each other in the passing direction, the distance between the meter sections (the main body 1 of the navigation device) of each vehicle can be reduced, thereby effectively utilizing the output of infrared rays. At this time, if an infrared input / output window is provided on the left side of the main body of the device, it will be convenient because of the position of the side stand and the position where the rider stands. , Two vehicles can be arranged side by side in the same direction and communicate side by side with the side stand upright.

Although the embodiment of the data input / output structure of the navigation device according to the present invention has been described above, the present invention is limited to a navigation device having a structure having various functions as shown in the above embodiment. It is needless to say that the present invention can be applied not only to motorcycles but also to other vehicles in which the driver's seat is exposed.

[0066]

According to the data input / output structure of the navigation device of the present invention as described above, the necessary data can be input and output together with the required data by infrared communication through the infrared input / output window of the device body. Therefore, data can be exchanged between the device body and an auxiliary input device (a personal computer or the like), and between the device and a navigation device having the same structure mounted on another vehicle without passing through another device. , Data can be exchanged directly.
