DESCRIPTION OF THE PREFERRED EMBODIMENTS [First Embodiment] A first embodiment of an input device according to the present invention will be described below with reference to FIGS.

As shown in FIGS. 1 and 2, the vehicle input device 10 includes a touch panel 14 as an "input operation means" in which a touch switch 12 is displayed on the screen. The touch panel 14 is an instrument panel 16
It is arranged at a predetermined position on the upper surface side of the console box 18 integrated with. On the other hand, a display screen (display) 22 is provided in the center cluster unit 20 of the instrument panel 16. It should be noted that the display screen 22 may be arranged in a part other than the center cluster part 20. These touch panel 14 and display screen 2
2 is connected to the controller 24 as "control means". The controller 24 is configured to enable the operation on the display screen 22 based on the input operation information (signal) input from the touch panel 14.

Here, in the present embodiment, a palm rest 26 for placing the palm of a driver, who is an operator, is formed integrally with the console box 18 on the rear side of the touch panel 14 described above. In addition, palm rest 2
Immediately below 6 is a push button type palm switch 28 as "palm placement detecting means". Palm switch 28
The touch panel 14 described above is connected to the controller 24, and the controller 24 controls the operation of the touch panel 14 based on the presence or absence of the input of the palm placement state detection signal from the palm switch 28.

Next, the operation and effect of this embodiment will be described.

The driver who is the operator is the touch panel 14
When the palm is not placed on the palm rest 26 on the rear side of the palm rest 26, the palm switch 28 is turned off. Therefore, the palm switch 28 does not output the palm placement state detection signal to the controller 24. Therefore, a stop signal is output from the controller 24 to the touch panel 14, and the touch panel 14 is brought into a stopped state (non-operating state). Therefore, the driver cannot perform an input operation using the touch panel 14 in this state.

When the driver places his palm on the palm rest 26 in this state, the palm switch 28 is turned on and a palm placement state detection signal is output to the controller 24. As a result, it is detected that the palm of the driver is placed on the palm rest 26. From the palm switch 28 to the controller 2
When a palm placement state detection signal is input to 4, the controller 24 outputs an operation signal to the touch panel 14. As a result, the touch panel 14 is brought into an input operable state, that is, an operating state (operating state). As a result, the driver performs an input operation (touch operation) using the touch panel 14.
It becomes possible to

In this state, the driver touches the touch panel 14
When the touch operation is performed on the screen, the input operation information input from the touch panel 14 by the controller 24 is determined to be valid. As a result, a predetermined display is made on the display screen 22 and an operation on the display screen 22 becomes possible.

On the other hand, when the driver finishes the operation and removes the palm from the palm rest 26, the palm switch 28 is turned off. Therefore, from the palm switch 28 to the controller 2
Since the palm placement state detection signal is not input to 4, the controller 24 determines that the input operation of the driver has been completed (or another operation has been performed once), and outputs the stop signal to the touch panel 14 again. As a result, the driver cannot perform the input operation using the touch panel 14.

Therefore, for example, even if the driver carelessly touches the touch switch 12 of the touch panel 14,
Even if an object hits the touch switch 12 carelessly, in these cases, the palm switch 28 does not operate because the palm mount state detection signal is not input from the palm switch 28 to the controller 24. Input operation information will not be erroneously output to the controller 24. Therefore, the system (vehicle-mounted function) is not accidentally activated by the controller 24.

As described above, in the vehicle input device 10 according to this embodiment, the palm rest 2 is provided behind the touch panel 14.
6 and the palm switch 28 are provided, the touch panel 14 is activated only when the palm of the driver is placed on the palm rest 26, the input operation information at this time is judged to be valid, and a predetermined system is activated. Therefore, it is possible to prevent an input contrary to the driver's intention, that is, an erroneous input. As a result, according to the present embodiment,
The suitability for mounting on a vehicle can be improved.

In particular, the vehicle input device 1 according to this embodiment.
In the case of 0, when the palm placement state detection signal is not input from the palm switch 28, the controller 24 forcibly brings the touch panel 14 into the stopped state, so that erroneous input can be reliably prevented. There is an advantage that you can.

Further, since the touch panel 14 is directly operated or stopped, the system is very simple. Therefore, the possibility of failure is very low, and reliability can be improved.

[Second Embodiment] Next, a second embodiment of the input device according to the present invention will be described with reference to FIGS. The same components as those of the above-described embodiment are designated by the same reference numerals and the description thereof will be omitted.

FIG. 4 is FIG. 1, FIG. 5 is FIG. 2, and FIG. 6 is FIG.
FIG. 3 is an overall configuration diagram, an enlarged view of main parts, and a block diagram corresponding to FIG. As shown in these drawings, the vehicle input device 50 according to the present embodiment is characterized in that a lock mechanism 52 as "locking means" is added to the touch panel 14.

The base end portion of the lid 54 is fixed to a part of the teeth provided on the outer peripheral portion of 0 in a state of being locked.

Next, the operation and effect of this embodiment will be described.

The driver who is the operator is the touch panel 14
When the palm is not placed on the palm rest 26 on the rear side of the palm rest 26, the palm switch 28 is turned off. Therefore, the palm switch 28 does not output the palm placement state detection signal to the controller 24. Therefore, a lock signal is output from the controller 24 to the lock mechanism 52, and the lid 54 is closed, as shown in FIG. Therefore, the driver cannot perform an input operation using the touch panel 14 in this state.

When the driver places his palm on the palm rest 26 in this state, the palm switch 28 is turned on and a palm placement state detection signal is output to the controller 24. As a result, it is detected that the palm of the driver is placed on the palm rest 26. From the palm switch 28 to the controller 2
When the palm placement state detection signal is input to 4, the controller 24 outputs an unlock signal to the lock mechanism 52. As a result, as shown in FIG. 5, the motor 58 is driven to rotate normally, and the lid 54 is wound around the sprocket 60. Therefore, the upper part of the screen of the touch panel 14 is opened,
The input operation is possible, that is, the lock is released. As a result, the driver can perform an input operation (touch operation) using the touch panel 14.

In this state, the driver touches the touch panel 14
When the touch operation is performed on the screen, the input operation information input from the touch panel 14 by the controller 24 is determined to be valid. As a result, a predetermined display is made on the display screen 22 and an operation on the display screen 22 becomes possible.

On the other hand, when the driver finishes the operation and removes the palm from the palm rest 26, the palm switch 28 is turned off. Therefore, from the palm switch 28 to the controller 2
Since the palm placement state detection signal is not input to 4, the controller 24 determines that the input operation of the driver is completed (or another operation is once performed), and outputs the lock signal to the lock mechanism 52. As a result, the motor 58 is driven in the reverse direction, and the lid 54 is pulled out (rewound) from the sprocket 60. Therefore, the upper part of the screen of the touch panel 14 is closed again, and the input operation is disabled, that is, the locked state.
As a result, the driver cannot perform the input operation using the touch panel 14.

Therefore, for example, the driver does not touch the touch switch 12 of the touch panel 14 carelessly, and the object does not touch the touch switch 12 carelessly. As a result, the input operation information is not erroneously output from the touch panel 14 to the controller 24. Therefore, the system (vehicle-mounted function) is not accidentally activated by the controller 24.

As described above, in the vehicle input device 50 according to the present embodiment, the palm rest 2 is provided behind the touch panel 14.
6 and the palm switch 28 are provided, and the lock mechanism 52 that enables switching between the locked state and the unlocked state is provided on the touch panel 14, so that the driver's intention is reversed as in the first embodiment described above. It is possible to prevent a wrong input, that is, an incorrect input. As a result, according to the present embodiment, it is possible to enhance the mounting suitability for the vehicle.

In particular, the vehicle input device 5 according to this embodiment.
In the configuration of 0, the lock mechanism 52 is provided on the touch panel 14, and when the palm mounting state of the driver is not detected by the palm switch 28, the screen of the touch panel 14 is forcibly covered with the lid 54 to make it inoperable. Therefore, there is an advantage that erroneous input can be surely prevented.

Further, in the vehicle input device 50 according to the present embodiment, the lid 54 covers the screen of the touch panel 14 when the driver does not operate the touch panel 14, and therefore the function of protecting the screen of the touch panel 14 is provided. (Damage prevention function) is obtained. Moreover, an effect of preventing foreign matter such as dust from adhering to or entering the screen of the touch panel 14 or the inside thereof can be obtained. As a result of obtaining these effects, according to the present embodiment, the durability of the vehicle input device 50 can be improved.

Although the flexible lid 54 is used in the present embodiment, the present invention is not limited to this, and a lid such as a slide opening / closing type may be used, and in a broad sense, "(opens and closes the screen of the touch panel 14)". Any element understood as "screen opening / closing means" can be applied.

[Third Embodiment] Next, a third embodiment of the input device according to the present invention will be described with reference to FIGS. The same components as those of the above-described embodiment are designated by the same reference numerals and the description thereof will be omitted.

FIG. 7 is FIG. 1, FIG. 8 is FIG. 2, and FIG. 9 is FIG.
FIG. 3 is an overall configuration diagram, an enlarged view of main parts, and a block diagram corresponding to FIG. As shown in these drawings, in the vehicle input device 70 according to the present embodiment, a lever-type operation lever 72 is adopted as the “input operation means”, and accordingly, a configuration different from that of the second embodiment is adopted. The feature is that a (lever) lock mechanism 74 is used as a "locking means".

More specifically, in the vehicle input device 70 according to the present embodiment, an operation lever 72 operated by a driver's finger is provided on the upper surface of the console box 18 in a protruding state. An input unit 76 is arranged on the lower end side of the operation lever 72 with a lock mechanism 74 interposed therebetween. The input unit 76 is connected to the controller 24,
The input operation signal is output to the controller 24. The lock mechanism 74 is also connected to the controller 24 so that its operation is controlled.

Various configurations can be applied to the above-mentioned lock mechanism 74. For example, while arranging a solenoid near the lower end of the operating lever 72,
The tip of the plunger is U-shaped or the like having an opening width slightly larger than the shaft diameter of the operating lever 72. And
Normally, the solenoid is not energized, and the tip of the plunger is held near the lower end of the operating lever 72 by the urging force of the urging means such as a compression coil spring. On the other hand, when the palm switch 28 is turned on, the solenoid is excited by the controller 24,
The plunger is pulled in against the urging force of the urging means,
All you have to do is to unlock it.

Next, the operation and effect of this embodiment will be described.

When the driver who is the operator does not place his / her palm on the palm rest 26 on the rear side of the operation lever 72, the palm switch 28 is turned off. For this reason,
A palm mounting state detection signal is not output from the palm switch 28 to the controller 24. Therefore, controller 2
A lock signal is output from 4 to the lock mechanism 74, and the operation lever 72 is locked. Therefore, the driver
In this state, the operation lever 72 cannot be swung and input operation cannot be performed.

When the driver places his palm on the palm rest 26 in this state, the palm switch 28 is turned on and a palm placement state detection signal is output to the controller 24. As a result, it is detected that the palm of the driver is placed on the palm rest 26. From the palm switch 28 to the controller 2
When the palm placement state detection signal is input to 4, the controller 24 outputs a lock release signal to the lock mechanism 74. As a result, the operation lever 72 becomes swingable, and the input operation is made possible, that is, the lock is released. As a result, the driver can perform an input operation (lever operation) using the operation lever 72.

In this state, when the driver performs an input operation using the operation lever 72, the controller 24 determines that the input operation information input from the input section 76 is valid. As a result, a predetermined display is made on the display screen 22 and an operation on the display screen 22 becomes possible.

On the other hand, when the driver finishes the operation and removes the palm from the palm rest 26, the palm switch 28 is turned off. Therefore, from the palm switch 28 to the controller 2
Since the palm placement state detection signal is not input to the controller 4, the controller 24 determines that the input operation of the driver is completed (or another operation is performed once), and outputs the lock signal to the lock mechanism 74. As a result, the lock mechanism 74 operates,
The swinging motion of the operating lever 72 is restrained again, and the input operation is disabled, that is, the locked state. As a result, the driver cannot perform the input operation using the operation lever 72.

Therefore, for example, the driver operates the operation lever 7
Even if 2 is inadvertently touched or an object is inadvertently hit on the operation lever 72, in these cases, the palm placement state detection signal is not input from the palm switch 28 to the controller 24, and the lock mechanism is locked. Since the operation lever 72 is restrained by 74, the input operation information is not erroneously output from the input unit 76 to the controller 24. Therefore, the system (vehicle-mounted function) is controlled by the controller 24.
Will not be accidentally activated.

As described above, in the vehicle input device 70 according to this embodiment, the palm rest 26 is provided behind the operation lever 72.
And the palm switch 28 is provided, and the operation lever 72 is provided.
On the other hand, since the lock mechanism 74 that enables switching between the locked state and the unlocked state is provided, the input contrary to the driver's intention, that is, an erroneous input is made, as in the first embodiment described above. Can be prevented. As a result, according to the present embodiment, it is possible to enhance the mounting suitability for the vehicle.

In particular, the vehicle input device 7 according to this embodiment.
In No. 0, the operation lever 72 is provided with the lock mechanism 74, and the movement of the operation lever 72 is forcibly restrained by the lock mechanism 74 when the palm mounting state of the driver is not detected by the palm switch 28. Therefore, there is an advantage that erroneous input can be surely prevented.
