Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle-mounted display control device, such as a navigation device, in which a display device is installed inside a vehicle and various information is displayed on the display device.

[0002]

2. Description of the Related Art Conventionally, there is known a navigation device in which a display device is installed in a vehicle compartment and a map and a current position of an automobile are displayed on the display device. In FIG. 3, reference numeral 1 is an instrument panel in the passenger compartment of an automobile, 2 is a display device of a navigation device installed in the center of the instrument panel 1, and this display device 2 is a display unit 3 as shown in FIG. The operation unit 5 is provided with various keys 4, and a map or the like is displayed on the display unit 3. By operating the various keys 4, map search, map scale change, and destination setting are performed. 6 is the driver's seat, 7 is the passenger seat, 8 is the rear seat,
Reference numeral 9 is a handle.

[0003]

However, in order to ensure safety, the above-mentioned conventional navigation device uses the keys 4 such as a map search key, a scale change key, and a destination setting key while the vehicle is running. Since the input is prohibited and the key input by the assistant sitting in the passenger seat 7 is also prohibited during traveling, the usability is poor.

The present invention solves the above-mentioned problems of the prior art. Although the key input by a driver during traveling is prohibited, the key input by a person other than the driver, for example, an assistant sitting in the passenger seat or the like. Provides an on-vehicle display control device that is not prohibited.

[0005]

In order to achieve the above object, the present invention has a key operation section for controlling the display of the display section in response to a key operation and is installed at a position where a driver can operate in the vehicle compartment. The key input control, the key input control means for prohibiting the key input of the key operation portion while the vehicle is running, and the switch means installed in the inoperable portion of the driver. The key input prohibited state of the means is released when the switch means is operated.

[0006]

The present invention has the above-described structure, and key input is prohibited by the key input control means while the vehicle is running.
Also, when an assistant or the like operates the switch means while the vehicle is running, the key input prohibition state by the key input means is released, and if the key is operated while operating the switch means, the key input is accepted and the display unit responds to the key input. The display is controlled.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS.
Will be explained together. In FIG. 1, the same parts as those in FIG. 3 are designated by the same reference numerals. In FIG. 1, reference numeral 10 denotes a push button provided on the left end of the instrument panel 1, and the installation location of the push button 10 cannot be operated by a driver sitting in the driver's seat 6 but operated by an assistant sitting in the passenger seat 7. Selected as possible.

In FIG. 2, reference numeral 3 is a display unit including a liquid crystal display device, 11 is a switch which is turned on when the push button 10 is pressed, and 12 is a GPS (Global Positioning System).
The GPS receiver 12 is a receiver that receives radio waves transmitted from a plurality of artificial satellites and calculates the current position of the vehicle from the received data.
The current position data output from is input to the control circuit 13. Reference numeral 14 denotes an optical disk reproducing device, which reads map data and the like recorded on an optical disk such as a compact disk and outputs the map data and the like to the control circuit 13. Reference numeral 15 denotes a key input control circuit. The key input control circuit 15 inhibits the key input of various keys 4 when a running pulse generated from a running pulse generator is input while the vehicle is running, and also switches the keys. When 11 is turned on, the above-mentioned key input prohibited state is released, and the key input of various keys 4 can be input to the control circuit 13. The control circuit 13 processes the current position data input from the GPS receiver 12 and the map data input from the optical disk reproducing device 14 in response to various key inputs, and changes the display of the display unit 3. The display unit 3 displays the map currently being driven and the current position of the vehicle.

In the above-mentioned embodiment, when the automobile starts traveling, a traveling pulse is generated by the traveling pulse generator,
This traveling pulse is input to the key input control circuit 15.
When the traveling pulse is input, the key input control circuit 15 is in a key input inhibition state, and input of a switching signal to the control circuit 13 from a switch that is turned on / off by operating the various keys 4 is prohibited. Therefore, a driver who is seated in the driver's seat 6 and is driving the vehicle operates the keys 4, and commands such as map search, scale reduction, and destination setting are not accepted, and safe driving is ensured. On the other hand, the passenger seat 7
When the assistant sitting on the button operates the push button 10, the switch 11 is turned on, and the key input inhibition state of the key input control circuit 15 is released. Therefore, when the assistant operates the key 4 of the display device while continuing to hold down the push button 10, this key command is input to the control circuit 13 and calculation based on this key command is performed to perform map search, map scale change, and purpose. The ground setting operation becomes possible. The assistant pushes the button 10 while driving.
When the pressing of is stopped, the key input control circuit 15 returns to the key input prohibited state again.

The above embodiment is an example of controlling the prohibition and cancellation of the key input of the key 4 arranged on the outer peripheral portion of the display unit 3, but a switch made of a transparent electrode is provided on the front surface of the display unit 3. The present invention can also be applied to a display device having a switch provided with a plurality of pairs of light emitting elements and light receiving elements on the outer periphery of the front surface of the display unit 3 for controlling prohibition and release of key input. is there. Further, in the above-described embodiment, the push button 10 for canceling the key input prohibited state is installed at a location where the passenger sitting in the passenger seat can operate, but the driver cannot operate the push button 10, It is also possible to install the push button 10 at an operable position.
Further, in the above embodiment, the key input is prohibited by the traveling pulse, but the key input may be prohibited by setting the traveling state when the side brake is released.
Further, although the above embodiment is an example of the navigation device, the present invention displays the state of the on-vehicle audio device on the display unit of the display unit, and the switch installed on the outer periphery of the display unit or the front surface of the display unit. It can also be used as a display device for adjusting the sound quality, volume, and sound field of an audio device.

[0011]

As described above, the present invention has the above-described structure. While the vehicle is traveling, key input by the driver is prohibited, but key input by anyone other than the driver is not prohibited, so that safe driving is ensured. And has the advantage of improving the usability of the display device.
