2. Description of the Related Art Navigation devices provide route guidance so that they can visit a destination for the first time by car. In recent years, performance and functions such as navigation accuracy, operability, and visibility have been improved. Technology development for this is being actively carried out, and various types are proposed. The navigation device includes a display screen used for setting a route and a display screen which is opened automatically at the time of guidance for guiding a route or in response to a driver's request. The display screen after the start of the guidance includes a section diagram that guides a wide area of several sections including the section currently being driven in at least the entire route including a plurality of sections in which a route is set, and an intersection for performing guidance at an intersection. It has figures etc.

[0003] These sections and intersections, as well as information on remaining distances, names, right and left turns, etc., are provided for intersections to be turned so that the route can be traveled without fail. Teach features, etc. so that they can be confirmed, provide guidance by voice as well as display, display the route on a map, guide on the route in actual running, and automatically follow the route You can scroll the map to check the route.

In such a navigation device,
In order to set a route, it is necessary to input a departure place and a destination. When the departure place and the destination are determined by this input, route search processing is performed from road information data around the departure place and the destination and between them. Is performed, and an optimum route is set from a plurality of routes. As an input method of the departure place and the destination, for example, the registration positions to be registered such as the departure place and the destination are divided into genres such as sightseeing, parking lots, restaurants, etc.
It also has a method of entering codes by dividing them into regions such as prefectures and cities, entering the code, entering a code number, displaying a menu and sequentially selecting and entering from the menu, and having node data. A road network is defined by linking the node data, and a method of inputting a position using coordinate values of east longitude and north latitude and a method of inputting a telephone number have been proposed. Furthermore, the current location or any departure location and destination
In addition to searching for routes between points, there is also a method in which a search is performed by designating a passing point, a priority of a toll road, and the like.

[0005] An example of this type of apparatus is disclosed in Japanese Unexamined Patent Publication No. 2-1.

In a conventional navigation device, when a destination is set, input keys are displayed in the same color on the destination setting screen both during stopping and during traveling. In addition, when an input key that cannot be operated during traveling is touched among the operated input keys, a message to that effect is displayed. In particular, if the user is a beginner, even if there are input keys that can be operated while driving and input keys that cannot be operated on the same screen, it is difficult to distinguish between operable input keys and operation prohibited input keys. Therefore, the input key for which operation is prohibited is operated. In this case, there is a problem that even if a message indicating that the operation cannot be performed is displayed, it is difficult to determine which input keys are prohibited from being operated.

[0007] In addition, even though the operation is prohibited, it looks like an input key that may be touched, so that a message is displayed indicating that the operation has been performed inadvertently and the operation cannot be performed. is there. Furthermore, even when the vehicle is stopped and touched because it cannot be operated during traveling, if it is touched at the same time as stopping, an operation prohibition message may be issued due to the processing timing on the system side, In some cases, if you want to input early, the input is delayed.

An object of the present invention is to solve the above-mentioned problems and to provide an information display device for a vehicle which facilitates identification of an input key whose operation is prohibited during traveling and enhances safety during traveling. It is intended for.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram for explaining one embodiment of a vehicle information display device according to the present invention, and FIG. 2 is a diagram showing an example of a screen transition by a key operation during traveling / stop.

In FIG. 1, a vehicle speed sensor reading unit 1
Is for reading a signal of a vehicle speed sensor composed of, for example, a wheel tachometer or an accelerometer.
Is to determine whether the vehicle is in a running state or a stopped state from a read signal of the vehicle speed. The day / night detector 3 detects day or night from the state of the illuminometer and the light switch. The touch detection unit 4 detects a touch position by scanning vertical and horizontal lines of the touch panel combined with the screen of the display. The pallet control unit 5 has a plurality of pallets in which the colors of the respective drawing elements are set, and controls switching of the pallets according to whether the pallet is running, stopped, or day or night. The screen transition is controlled according to the detection content of the touch position whether the vehicle is running or stopped. The screen drawing unit 7 draws the screen controlled by the screen transition control unit 6 with the color set in the pallet of the pallet control unit 5.

FIG. 2 shows an example of a screen transition controlled by the screen transition control unit 6. In the navigation device, in order to set a route, it is necessary to input and set the departure place and the destination as described above. When the departure place and the destination are determined by this setting, the departure place and the destination are set. A route search process is performed from the road information data in the vicinity of and in between, and an optimum route is set from a plurality of routes. FIG. 2 shows the destination setting screen used in this case.
As shown in (a), the type of input when setting a destination such as "telephone number", "facility name", "address", "home", "memory point", "last departure point" is selected. The input key is displayed.

The "telephone number" is used when a point registered with the telephone number in advance by inputting the telephone number is set as the destination, and the "facility name" is used for the city hall,
It is used when selecting and setting a destination by the name of a facility such as a station, a fire station, a police station, a library, a public hall, a parking lot, and the like. "Address" is used when specifying and setting an address as a destination, and "Home" is used when setting a home registered in advance as a destination. The “memory point” is used when the user registers an arbitrary point in advance and sets it as a destination, and the “previous departure point” is used when returning to the previous departure point. It is used to set as a ground. Of these, "Home" and "Last departure place" can be set destinations with one touch, but other input keys can be used for further operations such as number input, facility name selection and input. Will be needed.

Therefore, according to the present invention, an input key which can be operated even while traveling between "home" and "last departure place" where a destination can be set with one touch, and an input key which inhibits operation while other input keys are traveling. As shown in FIG. 2 (b), when the vehicle is stopped, the input keys displayed in the same color are in a running state. As shown in FIG. it's shown. When an input key for operation inhibition, for example, an input key for a telephone number is operated during traveling, a message to that effect is displayed as shown in FIG. 2 (c). When the "home" input key is operated, the point set input key is displayed as shown in FIG. 2 (d), and the destination setting is terminated by operating this key. In this case, the eight-direction cursor △ is displayed in an unusable color. The palette is switched so that the colors for the keys that cannot be used are inconspicuous colors such as dark colors and colors similar to characters.

Next, the processing of each unit shown in FIG. 1 will be described. FIG. 3 is a diagram for explaining a process of a traveling / stop determination unit, FIG. 4 is a diagram for explaining a process of a touch position detection unit, FIG. 5 is a diagram for explaining a process of a screen transition control unit,
FIG. 6 is a diagram for explaining a screen transition processing subroutine.

As shown in FIG. 3, the traveling / stop judging section 2 examines whether or not there is data from the vehicle speed sensor, and sets "running" if there is, and sets "stop" if not. The touch position detection unit 4 scans each line at regular intervals as shown in FIG. 4 to acquire touch position data, and notifies the screen transition control unit 6 of touch data if there is touch data. The screen transition control unit 6 acquires the touch data from the touch position detection unit 4 and the traveling / stop data from the traveling / stop determination unit 2 as shown in FIG. The screen transition process checks whether the touch position is valid as shown in FIG. 6, whether or not the vehicle is running, and whether or not the input key is an operation prohibition input key.
If the touched position is an operation-inhibited input key, an operation-inhibition message is displayed. If the touch position is not an operation-inhibited input key, screen information to be drawn is set.
Is given a screen drawing instruction to draw a predetermined screen. Also,
If the touch position is not valid and the vehicle is not running, a predetermined screen is drawn.

The day / night detector 3 checks at regular time intervals whether the light switch is on, as shown in FIG. 7. If the light switch is on, the light switch is set to "day"; if not, the light switch is set to "night". Set. On the other hand, the pallet control unit 5 checks at regular time intervals whether or not the vehicle is running and whether it is day or night, and according to the contents, determines whether the vehicle is stopped, the pallet in the daytime, Parked at night, pallets at night,
Set one of "Pallets at night while driving". The screen control unit 7 acquires palette data and screen information as shown in FIG. 9 and draws the color of each drawing element on the screen in the color of the palette data.

FIG. 10 is a diagram showing an example of correspondence between screen elements and palettes, FIG. 11 is a diagram showing an example of daytime palette data, and FIG. 12 is a diagram showing an example of nighttime palette data. On the screen to be drawn, the selection switch has an upper frame, a lower frame, a background, and a character drawing element, and the other screen elements have screen backgrounds of a display unit and an input unit, and a title. And display elements of each item, a drawing character of an item character, and a destination / passing point mark. In the present invention, each of these elements is assigned a pallet No. as shown in FIG. The pallet No. is set on the upper frame, the lower frame, and the background of the traveling operation selection switch and the traveling operation prohibition selection switch. 1, 13, 14, 5, 6, and 9 are separately set. The pallet data at daytime as shown in FIG. 11 and the pallet data at night as shown in FIG. In this way, in daytime and nighttime, the pallet data is changed so that the overall brightness does not become difficult to see due to daylight or nighttime darkness. The palette data is changed in the background. That is, in both the daytime pallet data shown in FIG. 11 and the nighttime pallet data shown in FIG. 12, the data other than the upper frame, the lower frame, and the background of the traveling operation prohibition selection switch are the same during stopping and traveling, Also, while the vehicle is stopped, the data of the upper frame, lower frame, and background of the traveling operation prohibition selection switch are the same as those data of the traveling operation enabled selection switch. The upper frame, lower frame, and background data are changed. In addition, the data of the upper frame, lower frame, and background of the operation-inhibited operation selection switch are R (red),
While G (green) and B (blue) use chromatic colors with different values while the vehicle is stopped, when the vehicle is running, the values of R, G, and B are the same in achromatic colors (gray or white, Black) and the same as the screen background. For example, in the daytime, if the white data is (F, F, F), bright data (D, D, D) close to the white data is obtained. , 0).

It should be noted that the present invention is not limited to the above embodiment, and various modifications are possible. For example, in the above embodiment, the pallets were switched between day / night,
It goes without saying that a common pallet may be used at night. In addition, the example in which the input keys are displayed on the screen and the touch operation is performed by combining the touch panel has been described. The present invention may be similarly applied to those configured as above. A key that inhibits input during traveling is a case where a key operation until a certain function is set consists of a plurality of designations, such as a facility name input. Therefore, a key input operation that can be performed by setting once or twice can be input even during traveling. Furthermore, the present invention may be similarly applied to a case where guidance for course guidance and information necessary for a user are presented on a screen. For example, for information that will take a long time to be obscured by the screen for confirmation, the information can be easily confirmed on the screen while traveling by controlling the display in the same way as the operation prohibition key when driving, necessary for the driver Information can be easily displayed. As one mode of controlling the color of such operation-prohibited keys and the like, if the color is the same as the background color,
You can virtually erase the key.
