The guide output means 6 includes a current position, an approach direction, a vehicle speed,
The guide property is determined based on information such as roads, the guide data is read from the guide data storage means 3, and the guide data is converted into a video signal and an audio signal for guidance and output. The switching means 7 is for switching the display output of the display output means 8 to a map image by the map image output means 4 or an image of guidance by the guide output means 6. Detects approach direction, vehicle speed, etc.,
Further tracking is performed, the current position and the approach direction are displayed on the map image, and when the guide property is searched and reaches the guide start point, the guide output means 6 switches to the video signal for the guide, and the video and audio are output. Start guidance. When the map display key of the operation means 1 is operated in this state, switching from the guide video to the map image is performed.

In the guide system according to the present invention having the above configuration, when the power is turned on by ACC-ON, a title image is displayed on the screen of the display output means 8, and the power is turned off by ACC-OFF. Then, when the power is turned on, the C storing the program
If the D-ROM is set, the program is started, and if the CD-ROM is set after the power is turned on, the program is started by operating the operation means 1.
When the guide program is started, the current position is sequentially detected and tracked as the vehicle travels, and a map image displaying an arrow in the approach direction with the north at the center of the current position is displayed on the display output means 8.
Is displayed on the screen, a guide property is searched from the current position, the traveling direction, and the vehicle speed, and a guide property is extracted from the guide data storage means 3, and guidance of the guide property is performed as appropriate.

Guided properties include point properties such as facilities and buildings, monuments, line properties such as bridges and streets, lakes and other large-scale facilities, national parks and plains, and other regional zones. It is divided into properties. For point properties, the timing of starting guidance is limited, but line properties and zone properties can be selected within a certain range. Therefore, relatively, line properties and point properties have priority over zone properties, and line properties and zone properties have room to output delays even after giving priority information on important point properties. Can be provided. For example, if there is no point property to guide, the priority may be set so that line properties and zone properties are extracted. First, if a point property is not explored, a line property is searched. You may make it search for a zone property.

For guidance, a guide property stored in the guide data storage means 3 is searched from information such as the current position, approach direction, and vehicle speed. When a vehicle approaches the guide property, the guide output means 6 automatically provides guidance. The video and the guidance voice are output, and the guidance is started when the guide output unit 6 determines that the following conditions are satisfied at the guidance start point set for each guidance property. The guidance start condition is shown in FIG.
As shown in FIG. 2, when the vehicle traveling direction is within the guidance start point approach direction ± A °, and when the vehicle position is within Bm in consideration of the vehicle speed from the guidance point coordinates as shown in FIG. That is, the property is an unguided property and is not guiding other properties. In addition, by giving a manual guide instruction by the operating means 1, the vicinity of the current position (vehicle) (guide entry point approach direction ± A '°, distance between the guide point and the current position within B'm: A' ° ≧ A
°, B ′ ≧ B).

The condition for ending the guidance is based on the fact that the guide data being output is output to the end. However, when the operation stop switch is operated by the operating means 1 or when another property guidance point is reached, Compare the priority of the guide unit of the property currently being guided with the first guide unit of the other property, and if the priority of the other property is higher, stop at the guide unit being guided. In other words, the guide data is composed of a plurality of guide units including, for example, one image and a few seconds of sound, and execution / stop of the guidance is determined for each guide unit, and further, by setting priorities, When a plurality of guide properties satisfy the guide start condition, the selection of the execution of the guide, the adjustment of the length, and the stop of the guide may be determined based on the priority.

There are a plurality of guide points for one guide article, for example, as shown in FIG.
There will be two guide points, and the position according to east longitude and north latitude and the approach direction of the vehicle will be defined. Then, among the guided properties, the property that has been guided is stored as the already-guided property so that the same property is not repeatedly provided with guidance. In this case, as shown in FIG. 4, a property for which guidance has been completed by one or more guide units may be set as a guided property, or a condition that a predetermined guide unit with a higher priority has completed guidance, or a guide unit may be used. It may be an existing property every time.

Next, a specific example of the guidance will be briefly described. FIG. 5 shows a situation in which a vehicle passes near the Kaminarimon Gate in Asakusa. The Kaminarimon of the guide object is, for example, a guide video as shown in FIG.
Is stored in Therefore, the guide output unit 6 searches the guide data storage unit 3 for a property that satisfies the above-described guidance start condition based on the current position, approach direction, and vehicle speed of the vehicle obtained from the current position detection unit 5. And
When Kaminarimon is searched for as a guide property, the guide data of Kaminarimon's guidance video and guidance voice is read, converted into signals, and output. When the guide image signal is output, the switching means 7 outputs the guide image as shown in the figure from the display output means 8 by switching the map image display signal from the map image output means 4 to the guide image signal, and A guidance voice such as "Edo emotion ..." is output to the output means 9. When such guidance is completed, the guide output means 6 stores the Kaminarimon as a previously-guided property, so that even if the person passes through Kaminarimon again from a different direction, repeated guidance can be prevented.

However, when such property guidance is started, the current position of the vehicle, the location of the property, and the surroundings of the property may not be known. In such a case, in the present invention,
When a map key is instructed by operating the map key by the operating means 1, the switching means 7 guides the guide output means 6.
Is switched to the display signal of the map image by the map image output means 4 from the guide video signal by the above, and the display can be switched to the map image as shown in FIG. During this time, the guidance voice is output, but may be stopped. By doing in this way, it is possible to switch to the map image at any time even after the property guidance is started, and to obtain information such as the position of the property and the surrounding situation of the property.

Then, when each guide unit is completed, the video / audio output processing unit 36 notifies the guidance control processing unit 35 of the completion. The guidance flag of the information that has already been provided is set in the already-guided information processing unit 34 by the guidance control processing unit 35.

The processing flow of the entire guide system according to the present invention will be described below. First, the entire flow is shown in FIG.
As shown in (1), the process is started by turning on the power, and the entire apparatus is initialized (step S1). Thereafter, processing of an external input signal by a remote controller or the like is performed (step S2), and the current position is detected using various sensors and the current position is tracked (step S3). further,
The guided property is detected according to the current position, and when there are a plurality of guided properties, which property is to be guided is determined and the guided property is output (step S4). In addition, the FG process for switching the screen during the guidance output is performed together with the guidance output (step S5). Then, output processing of the map image and the video / audio of the guide property is performed (step S6).

The guidance article detection process in step S4 is performed as shown in FIG.
As shown in (1), first, it is checked whether or not the guidance flag FG set to "1" during guidance is "1" (step S1).
1). If the guiding flag FG is not "1", the guide property is searched (step S12). If there is a guide property, the guide data of the property is read from the CD, and the video output signal, the audio output signal, and the status signal are output. To output a video / audio output control process, and set a guidance flag FG = 1 and a map image switching flag GDFG = 1 (steps S13 to S15). Thereafter, it is determined whether or not the guidance stop key and the manual key have been operated, and if not, it is determined whether or not the guidance has ended (steps S16 to S18).

In the video / audio output control processing in step S15, as shown in FIG. 9, it is determined whether or not the guidance start position has been passed based on the detected current position (step S3).
1), after passing the guidance start position, the guide output means 6 outputs a start sound signal and outputs, for example, a warning sound of "pawn" (step S32). Then, a video signal, an audio signal, and a status signal are output from the guide output unit 6. The output audio signal is reproduced as audio guidance by the audio output means 9, and the display signal of the map image is switched to the video signal by the status signal in the switching means 7.
The guide video is reproduced by the display output means 8. Here, the guidance flag FG = 1 and the map image switching flag GDF
G = 1 is set (step S33).

If the guiding flag FG is "1" in the judgment processing of step S11, the property other than the guiding property is searched (step S23), and if so, whether the property has a higher priority than the guided property. It is checked (steps S24 to S25) whether it is high, and if the guidance is completed up to the break of the guide unit of the property being guided (step S26), the next step S20 and subsequent steps are executed.

If it is determined in step S16 that the guide stop key has been operated, the manual key is operated in step S17 to determine the manual mode, and if the manual mode flag MF = 1 is set (step S19), the process proceeds to step S17. If the guidance ends in S18, or if it is determined in step S26 that the guidance has been completed up to the break of the guide unit of the property being guided, the reproduction of the video and audio is immediately terminated, and the guidance flag FG = 0 is set. It is set (step S20). At this time, if one or more guide units have been guided, the already-guided flag of the property is set (steps S21 to S22).

The screen switching FG process in step S5 is as follows.
For example, as shown in FIG. 10A, first, it is checked whether or not the property is being guided (step S41). If the property is not being guided, the time T is set to 0 and the map image switching flag GDFG is set to 0 (step S48, S49) If the property is being displayed,
Further, it is checked whether or not the time T = 0 (step S42).
If the time T = 0, it is checked whether or not the map key has been pressed (map command) (step S43). If the map key has been pressed, the time T = a and the map image switching flag G
After setting DFG = 0 (step S44), if the map key has not been pressed, the routine returns. If T = 0 in step S42, T-1 →
T is set (step S45), it is checked again whether or not the time T = 0 (step S46). If T = 0, the map image switching flag GDFG is set to 1 (step S47). If T is not 0, the routine immediately returns. When the map key is operated (turned on) in this manner, the screen is switched with the flag GDFG = 0, and the screen returns to the property guidance screen after a certain time from T = a to T = 0.

The screen may be switched each time the map key is pressed. In this case, FIG.
As shown in (b), whether the property is being guided (step S5)
1) It is checked whether or not the map key has been pressed (map command) (step S52). If the property guidance is not being performed, the map image switching flag GDFG is set to 0 (step S54). If the map key is not pressed even during property guidance, the flag GDFG is maintained.
An exclusive OR of FG and “1” is calculated and a new flag G is calculated.
By setting the value to the value of DFG, the flag GDFG is inverted and the screen is switched (step S53). In any case, the guide system according to the present invention should be able to switch to the map image at any time when it is desired to confirm the current position during guidance.

Then, in the video / audio output processing in step S6, as shown in FIG. 11A, first, it is checked whether or not the map image switching flag GDFG = 1 (step S6).
1) If GDFG = 1, a sightseeing guide screen is output (step S62); if GDFG = 1, a map screen is output (step S63). That is, only the screen is switched depending on whether or not the map image switching flag GDFG = 1. Of course, not only screen switching but also audio output may be stopped. In this case, as shown in FIG. 11B, it is checked whether or not the map image switching flag GDFG = 1 (step S71). If GDFG = 1, a sightseeing guide screen and voice are output (step S72). ), GDFG
If not = 1, the map screen is output and the tourist guidance voice is turned off (step S73).

The wireless remote controller is composed of, for example, keys as shown in FIG. In FIG. 12, the start / stop key is changed from the state where the title image is displayed to the CD-RO.
A key for starting the program stored in M or stopping the program when the map image is displayed. The north-south key is used to reverse the north and south of the map when the map image is displayed. Is the key. This means that if the direction toward the north with respect to the east-west direction is the approach direction, a map image with the north facing up is displayed, but if the direction toward the south with respect to the east-west direction is the approach direction, Since the direction below the screen is the approach direction, the operation is performed when switching to a map image with south facing up, or vice versa. The manual key is used to start manual guidance if there is a manual guide property while a map image or a guide image is being displayed, or to start guidance for the next candidate guide property during manual guidance. . The detail key and the wide area key are operated to switch the scale of the map image or to display the scale. The set key is
This operation is performed when performing initialization or when correcting the current position in a map image. The stop key is displayed on the automatic guidance screen,
This key is used to stop the guidance on the manual guidance screen, such as when canceling the guidance and returning to the map image, canceling the initialization, canceling the correction of the current position, or the like. The arrow keys are operated to move the current position cursor when correcting the current position of the map image. The map key is
This key is operated when switching and displaying the guide video and the map image, and issues a map command.

If the memory is erased due to the initial state, removal of the battery or other reasons, and the current position is not stored, it is necessary to set the current position. In this case, the current position is set by moving the current position on the map image using the arrow key, the detail key, and the wide area key and using the set key as shown in FIG.

In the automatic guidance mode, as described above, a map image is displayed when there is no guidance object nearby and no guidance is being provided. In this case, the property is still being searched,
By operating the detail key and the wide area key, the scale of the map image can be changed as shown in FIG. 14, and by operating the north-south key, the north-south direction of the map image can be reversed as shown in FIG. The current position of the vehicle can be corrected as shown in FIG. 16 by operating the set key, the correction key, and the arrow keys.
