DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a car navigation apparatus according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic configuration diagram showing a car navigation device 1 (navigation device 1) according to an embodiment of the present invention.
The navigation device 1 includes an operation unit 2, a vehicle running state detection unit 3, a display data storage unit 4, a voice data storage unit 5, a display unit 6, a voice output unit 7, a control unit 8, and an output. Changing means 9 is provided.
[0010]
The operating means 2 has a knob that can be gripped by an operator, and is formed to be displaceable in the front-rear directions 2A and 2B (see FIG. 4) by an input operation from an operator (in this case, a vehicle occupant). ing. The operator can switch the operation items to be selected as will be described later by operating the operation means 2 in the front-rear direction. In addition, by operating the operation unit 2 in the same manner (for example, by performing an operation such as continuously displacing the operation unit 2 back and forth), it is also possible to activate or stop the sound output.
Although details will be described later, the switching speed of the selection item can be adjusted by the operation of the operation means 2. This operation can be performed, for example, by continuing the displacement in the front-rear direction continuously for a predetermined time or more, and is set so that the switching speed can be adjusted without the operator viewing it.
[0011]
The vehicle running state detection unit 3 includes a vehicle speed sensor, detects the vehicle speed by the sensor, and transmits the output value to the control unit 8.
The display data storage means 4 stores various operation items 6A to 6E and item content data corresponding thereto. The voice data storage means 5 stores voice identification vocabulary data corresponding to the data stored in the storage means 4.
The display means 6 includes a display screen 16 and displays operation items on the display screen 16. Further, it is possible to display only the item frame of the operation item on the display screen 16, display the item content in the item frame, or change the display state of the operation item to be selected.
The sound output means 7 includes a speaker and outputs sound from the speaker.
[0012]
The control means 8 is connected to the above-described means 2 to 7, respectively. The control means 8 reads the data of the operation items 6A to 6E from the display data storage means 4 and displays the operation items 6A to 6E on the display screen 16 of the display means 6. When performing voice output, the voice identification vocabulary data corresponding to the data of the operation items 6A to 6E is read from the voice data storage means 5 and outputted from the speaker of the voice output means 7. In the present embodiment, all the operation items 6A to 6E are the targets of audio output.
[0013]
Further, the control means 8 determines whether or not the vehicle is in a running state according to the output value transmitted from the vehicle running state detection means 3. This determination can be performed, for example, by comparing a preset reference value with the output value, and setting the running state when the output value is greater than or equal to the reference value and setting the stop state when the output value is less than the reference value. .
The control unit 8 includes an output change unit 9, and the output change unit 9 controls the display unit 6 and the audio output unit 7 according to the determination result. This will be described with reference to FIGS.
[0014]
FIG. 2 is an explanatory view showing an example of a screen displayed on the display means 6. The figure shows a display screen 16 when the control means 8 determines that the vehicle is stopped. In this case, the operation items 6A to 6E are displayed on the display screen 16, and the contents of the items are displayed in the display frames of the operation items 6A to 6E. Further, the control means 8 displays the selected operation item (in this case, 6E) on the display screen 16 so as to be distinguished from the other operation items 6A to 6D. This item distinction may be performed, for example, by changing the color of the selection item, may be performed by blinking, or may be performed by changing the size.
[0015]
Further, the operation items 6A to 6E on the display screen 16 are displayed based on the rules (in this case, in the order of categories). Accordingly, the operator can grasp the relevance of the operation items 6A to 6E, and can estimate the position of the operation item (request item) requested by the operator without performing visual inspection. .
The operator can switch the selected operation item to the request item (for example, 6A) by switching the operation item 6E being selected by operating the operation means 2 in the front-rear direction.
In addition, when the vehicle is stopped, the operator can arbitrarily select whether or not sound output is possible by operating the operation means 2, and when the sound output is selected, the item content of the selected operation item is sound output. The sound is output from the means 7.
[0016]
FIG. 3 is an explanatory diagram showing an example of a screen 16 displayed on the display means 6. The figure shows a display screen 16 when the control means 8 determines that the vehicle is in a running state. When it is determined that the vehicle is in the running state, the output change means 9 switches the display screen 16 from the state shown in FIG. 2 to the state shown in FIG. That is, when it is determined that the vehicle is in a running state, the item content is deleted from each of the operation items 6A to 6E, and only the item frame is displayed. In addition, the voice output means 7 is forcibly activated by the output changing means 9, and the item contents of the selected operation item 6D (in this case, “Yuench”) are output as voice.
[0017]
As described above, in the traveling state of the vehicle, the item content is erased from the display screen 16, so that the operator does not need to discriminate characters when viewing the display screen 16. In addition, since the operation items 6A to 6E to be voice output targets are displayed based on the rules, if the operator instantaneously views the display screen 16, the operation item 6D output by voice and the request item are displayed. (For example, the positional relationship with the operation item 6A) can be easily grasped.
[0018]
Therefore, the operator can easily recognize the operation procedure for changing the selection target of the request item 6A from the operation item 6D being selected (in this case, the operation means 2 is displaced forward three times) and visually Without this, the operation means 2 can be operated. Further, when the operation item to be selected is switched by the operation of the operation means 2 (for example, when the operation item 6D is switched to the operation item 6C), the item content of the switched operation item 6C is the above-described item. Since the sound is output by the sound output means 7, the operator can perform the operation relying only on the sound. Therefore, it is possible to reduce the burden of visually recognizing the display screen 16 while the vehicle is traveling, and to enhance operability while ensuring safety.
[0019]
If the number of operation items is large and it is difficult to display all the operation items on the display screen 16 of the display means 6, the control means 8 displays the operation items on the display screen 16 as shown in FIG. Let me. FIG. 4 is an explanatory diagram of a display screen in a running state when the number of operation items is large, and corresponds to FIG. As shown in the figure, on the display screen 16, the scroll bar 10 and the slider 11 are displayed together with the item frames of the operation items 6A to 6E, and the total number of operation items and the operation item being selected are displayed. The position in the whole (6D in this case) can be determined by instantaneous visual inspection.
[0020]
That is, the total number of operation items is represented by the length of the scroll bar 10 and the amount of movement of the slider 11, and the position of the selected operation item 6D with respect to the entire operation item depends on the position of the slider 11 displayed inside the scroll bar 10. Represent. Further, by changing the size of the slider 11, the ratio of the operation items 6A to 6E displayed on the display screen 16 to the whole may be represented. The operator can change the operation items 6 </ b> A to 6 </ b> E to be displayed on the screen 16 by operating the slider 11 via the operation unit 2.
[0021]
In addition, when the operator determines that the position of the selected operation item is away from the position of the request item, the operator can intentionally increase the operation speed of the operation unit 2. Thereby, even when the number of operation items is large, a quick operation can be performed.
In the embodiment, only the display frame is displayed on the display screen 16 in the running state. However, the present invention is not limited to this, and the display item may be changed to another graphic design. In the running state, the voice output means 7 is set to be forcibly operated. However, the voice output means 7 may be further stopped by the operator's setting.
[0022]
【The invention's effect】
As described above, according to the first aspect of the present invention, when the operator (passenger of the vehicle) visually recognizes the display means, it is not necessary to distinguish characters, and if the display means is visually recognized instantaneously. Since the positional relationship between the operation item (selected item) output by voice and the request item can be easily grasped, the operation procedure for changing the selection target of the request item from the selected item can be easily recognized. It is possible to operate the operating means without visual observation, and it is possible to intentionally increase the operating speed of the operating means as required. Therefore, it is possible to reduce the burden of visual work on the display screen while the vehicle is traveling, and to improve operability while ensuring safety.
