DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a screen operation device for a vehicle.

[0002]

2. Description of the Related Art As a method of operating various vehicle devices installed in a vehicle, operation screens of various devices such as an air conditioner, an audio device and a navigation device are displayed for each mode on a display screen of a display device mounted on the vehicle, and the operation is performed. There is a screen operation method of performing an operation while performing a switch input along a screen (for a similar technique, see Japanese Patent Application Laid-Open No. 2-287615). In this type of operation method, the operation screen is switched for each switch input, and the user can proceed while selecting the type of operation.

In this screen operation method, when an operation is stopped on a certain operation screen and a switch input waiting state elapses over a set time (time-out time), the operation screen is forcibly changed to a predetermined initial screen. A return timeout function is provided. This is because if the display screen is stopped in the middle of the operation screen, other functions cannot be operated immediately.

[0004]

However, in such a conventional technique, if a time longer than a set timeout time elapses during the operation, the operation screen is forcibly changed to the initial screen. The operation screen returns to the initial screen even if, for example, it takes time due to a driving operation (such as a steering wheel operation or a brake operation during a curve) during the operation. Therefore, the driver needs to restart the operation from the beginning, and the operation is very troublesome.

The present invention has been made by paying attention to such a conventional technique, and provides a vehicle screen operation device in which an operation screen does not return to an initial screen even if time elapses due to driving operation. Things.

[0006]

According to the first aspect of the present invention,
The operation screen displayed on the display screen is sequentially switched by a switch input to operate the vehicle equipment, and the operation screen is changed to a predetermined initial screen when a predetermined timeout time or more elapses in a state of waiting for switch input. A screen operation device for a vehicle having a return time-out function,
Vehicle screen operation, comprising: vehicle driving operation state detection means; and timeout time adjustment means for adjusting a timeout time so that the operation screen does not return to the initial screen in response to a signal from the driving operation state detection means. apparatus.

According to the first aspect of the invention, the operation screen can be prevented from returning to the initial screen during the driving operation by the timeout time adjusting means. The operation can be continuously performed after the driving operation without interruption.

[0010] According to a second aspect of the present invention, when the driving operation is performed during the timeout period, the timeout period adjusting means cancels the time count and starts counting again.

According to the second aspect of the present invention, since the timeout time adjusting means cancels the timeout time and counts again, the operation screen is maintained without being switched even during the driving operation.

According to a third aspect of the present invention, the timeout time adjusting means extends the timeout time by the time of the driving operation state when the driving operation is performed during the timeout time.

According to the third aspect of the present invention, the timeout period is extended by the time of the driving operation state by the timeout time adjusting means, so that the state of the operation screen after the driving operation is always the same as that before the driving operation. .

[0012] In the invention according to claim 4, the timeout time adjusting means extends the timeout time by a predetermined time predetermined for each driving operation state when a driving operation is performed during the timeout time. .

According to the fourth aspect of the present invention, the time-out time adjusting means has a structure in which the time-out time is postponed by a predetermined time predetermined for each driving operation state, so that it is necessary to count the time required for the driving operation. Therefore, it is easy to control the timeout time.

According to a fifth aspect of the present invention, there is provided a learning adjusting means for learning the time required for switch input on the operation screen and adjusting the set time itself of the timeout time.

According to the fifth aspect of the present invention, the time required for switch input can be adjusted by learning the time required for switch input by the learning adjusting means. In the case of a person who tends to set the timeout time, the set time of the timeout time itself becomes longer. Therefore, even when the switch input is delayed at times other than the driving operation, the operation screen is not switched to the initial screen.

[0016]

According to the present invention, the operation screen can be prevented from returning to the initial screen during the driving operation by the time-out time adjusting means. Therefore, the operation screen is maintained and the operation is interrupted. Instead, the operation can be performed continuously after the driving operation.

Further, if the learning adjusting means is provided, the time required for switch input can be learned and the set time itself of the timeout time itself can be adjusted. In the case of a person, the set time of the timeout time itself becomes longer. Therefore, even when the switch input is delayed at times other than the driving operation, the operation screen is not switched to the initial screen.

[0018]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

FIGS. 1 and 2 show a first embodiment of the present invention. FIG. 1 is a block diagram illustrating a configuration of the screen operation device according to the first embodiment. First, display means 1
Will be described. The display unit 1 includes a display control unit 4 linked to the switch 3 of the vehicle device 2. A signal from the display control unit 4 activates a drawing function unit 5.
An operation screen selected from the stored drawing data section 6 is displayed on the display screen 7. The operation screen displayed on the display screen 7 is sequentially switched to another operation screen when there is an input from the switch 3. The switch 3 may be a screen input type for directly pressing the display screen 7 or a display screen 7.
The button may be a button provided in another part. The vehicle devices operated by the switch 3 include an air conditioner, an audio,
Navigation.

The display control section 4 is combined with a timeout time adjusting means 8. The time-out time adjusting means 8 provides the display control unit 4 with a time-out function for returning the operation screen to a predetermined initial screen when a time longer than the time-out time set in the state of waiting for the input of the switch 3 has elapsed. And the length of the timeout period is controlled.

The timeout time adjusting means 8 is connected to the driving operation state detecting means 9. In the driving operation state detecting means 9, the driving operation determination section 11 can determine the driving operation state from the signal detected by the driving operation detection section 10. Then, the driving operation state is transmitted to the timeout time adjusting means 8.

The driving operation state is a state in which an operation necessary for the driving operation is performed, and for example, there are the following states. Further, as the driving operation detecting unit 10 that can be used for detecting those driving operations, there are those shown in parentheses.

-Steering wheel operation (rudder angle sensor)-Brake operation (brake lamp)-Left / right turning operation (rudder angle sensor and turn signal)-Shift operation (inhibitor switch and shift gauge sensor)-Light operation (light switch)-Wiper operation (Wiper switch) ・ Hazard switch operation (Hazard switch)

Next, the operation flow of this embodiment will be described with reference to FIG. The timeout time adjusting means 8 of this embodiment employs a method of canceling the time count of the timeout time and recounting.

First, an initial screen is displayed on the display screen 7 (step S1). When a predetermined operation is performed from the initial screen, the first operation screen is displayed (step S2).
A switch operation is started based on the displayed operation screen (step S3), and a time count as a timeout function is started from this point (step S4). Then, after starting the time counting, it is determined whether or not a driving operation is being performed based on a signal from the driving operation state output means 9 (step S5).
Immediately cancel the time count and go to step S4
Return to the start of time counting and recount. Therefore, even if a long time is required for the driving operation, the operation screen in step S2 is maintained and the operation is not interrupted, and the operation can be continued after the driving operation.

If no driving operation is being performed, it is determined in step S6 whether or not the next switch input has occurred within a set time (timeout time). If there is a switch input, the next operation screen is displayed (step S7). If there is no next switch input within the set time, the time count ends within the set time (step S
8) In step S9, the time (Z) from the time count start (X) to the time count end (Y) is compared with the set time (t). If the time (Z) has not passed the set time (t), the processing is repeated from step S5. When the time (Z) exceeds the set time (t), the timeout function is activated, and the process returns to step S1 to display the initial screen.

As described above, in this embodiment, when a driving operation is detected, the timeout period is canceled and counting is performed again. Therefore, even during the driving operation, the operation screen is maintained without being switched, and the operation is performed again. Nothing.

In this embodiment, the timeout period is canceled and the counting is performed again. However, another control method may be employed. For example, the timeout time may be postponed by the time of the driving operation state.
Then, the state of the operation screen after the driving operation is always the same as before the driving operation. In addition, since the type of the driving operation is known in the driving operation determination unit 11, the timeout time may be postponed by a predetermined time predetermined for each type of driving operation state. Then, it is not necessary to count the time required for the driving operation, and the timeout time can be easily controlled.

FIG. 3 is a diagram showing a second embodiment of the present invention. In the second embodiment, learning adjustment means 12 for learning the time required for switch input on the operation screen and adjusting the set value of the timeout time itself is added while being connected to the timeout time adjustment means 8. The time required for operating the switch 3 varies from driver to driver, and if the driver tends to take a long time, the switch input may be delayed and the operation screen may be switched to the initial screen even during the driving operation. There is. In the second embodiment, in order to prevent such a situation, the learning adjustment unit 12 increases the time-out period itself if the switch operation input requires a long time. I have. Then, even when the switch input is delayed at times other than the driving operation, the operation screen is not switched to the initial screen.
