DESCRIPTION OF EMBODIMENTS Hereinafter, a vehicle-mounted touch panel according to the present invention will be described in detail based on the drawings illustrating an embodiment thereof.
In the external view shown in FIG.
Reference numeral 1 denotes a car navigation device installed on a dashboard near a driver's seat of a vehicle such as a passenger car, and 2 denotes a display device having a touch panel function.
Reference numeral 3 denotes an enlargement instruction switch set in a part of the display device 2, and reference numeral 4 denotes a control device built in the car navigation device 1.

In the block diagram shown in FIG.
5 is a car navigation system control device, 6 is a GPS antenna, 3 is the enlargement instruction switch, 4 is the control device, and 2 is the display device.
The control device 4 is included in the car navigation system control device 5 and operates based on the position information of the mounted vehicle obtained based on the signal from the GPS antenna 6 and the map information stored in advance. Car navigation function is realized.
When the enlargement instruction switch 3 is operated, the control device 4 changes the operation button image displayed on the surface device 2 from the normal shape as shown in FIG. The display is switched to an enlarged shape as shown in FIG.

In the car navigation device 1 configured as described above,
In a state where the enlargement instruction switch 3 is not operated, the control device 4 displays the operation button images 21A, 22A, 23A, and 24A having normal shapes as shown in FIG.
For example, when the passenger in the passenger seat tries to operate, when the enlargement instruction switch 3 is operated when there is strong vibration and the fingertip is shaken and it is difficult to touch the target operation button image accurately, The control device 4 switches the operation button image displayed on the front device 2 to the operation button images 21B, 22B, 23B, and 24B enlarged vertically as shown in FIG. The sensing area is also switched and displayed corresponding to the button image.
Therefore, even if the fingertip is shaken when trying to touch the target operation button image under the influence of strong vibration, it is possible to easily touch the vertically long sensing region.

  Note that the operation button image may be an image as shown in FIGS. 4A and 4B instead of the image as shown in FIGS. Normally, operation button images 21C, 22C, 23C, and 24C having a normal shape are displayed as shown in FIG. 4A, but when the enlargement instruction switch 3 is operated, as shown in FIG. The operation button images 21D, 22D, 23D, and 24D having the vertically expanded area are switched and displayed, and the sensing area is also switched and displayed corresponding to the operation button image.

Further, the car navigation device 1 may incorporate a vibration sensor 31.
And if the vibration of the said vehicle detected by the said vibration sensor 31 exceeds predetermined intensity | strength, it will comprise so that a vibration detection signal may be output. When this vibration detection signal is output, even if the enlargement instruction switch 3 is not operated, the control device 4 displays the operation button image displayed on the surface device 2 as shown in FIG. ), The sensing area is also enlarged vertically corresponding to the operation button image.
Since the vibration of a moving passenger car is often in the vertical direction, it becomes easy to touch by enlarging it vertically as shown in FIGS. 3B and 4B.

In a state where the vehicle is turning a sharp curve, a lateral vibration or acceleration occurs. However, it is dangerous to operate the car navigation device 1 in such a state, which is not normally performed.
Note that it is sufficient for the vibration sensor 31 to detect only vertical shaking.
When returning to a state where there is no strong vibration, the control device 4 displays an operation button image having a normal shape as shown in FIGS. 3A and 4A on the surface device 2.
Therefore, a lot of information can be displayed.
The operation button image enlarged and displayed as described above may be limited to a button image corresponding to a highly necessary operation. Such a limitation is set in advance according to the display state or the like.

The enlargement instruction switch 3 may be disposed on a touch panel, but can be replaced with an operation means such as a separate switch.
Instead of the vibration detection signal from the vibration sensor 3, a vehicle speed signal from a vehicle speed sensor, a side brake operation signal, or the like may be used.
Further, instead of expanding the area of the sensing region in the vertical direction, it may be expanded in the vertical and horizontal directions. In any case, the sensing area may be enlarged at least in the vertical direction.

The present invention can be applied not only to car navigation devices but also to operation buttons of car audio devices and various in-vehicle accessory devices.
