Embodiment approach 1

[0026] First, the "vehicle device" in the present invention refers to a device installed in a vehicle such as a car navigation system or a car audio system, and refers to a device that has a use screen between the vehicle passenger (hereinafter referred to as the user) and the vehicle passenger (hereinafter referred to as the user). Displayed man-machine interface (man-machine interface) equipment.

[0027] The vehicle-mounted display device according to the present invention is used as the display device of the above-mentioned vehicle-mounted equipment, and displays information on a display screen as a human-machine interface or in a display frame of an instrument panel.

[0028] Here, problems in the case of switching only character string fonts without changing the screen layout on the display screen of the car navigation system will be described.

[0029] figure 1 It is a diagram showing an example of font switching on a display screen, and shows a case where a font is sw...

Embodiment approach 2

[0090] Figure 8 It is a block diagram showing the configuration of a car navigation device to which the car-mounted display device according to Embodiment 2 of the present invention is applied. exist Figure 8 In the illustrated car navigation device 1A, the structure for realizing the navigation function and the structure for realizing the function of the car-mounted display device according to the second embodiment are the same as those described in the above-mentioned first embodiment. figure 2 are basically the same, but the difference is that the set value storage unit 18 is set instead of figure 2 The vehicle information acquisition unit 13 in the shown structure. The set value storage unit 18 is a storage unit that stores the set values ​​of the display types described in Embodiment 1 above.

[0091] The combination of the screen design and the font can be switched according to the user's setting. In this case, there is an advantage that the screen display that th...

Embodiment approach 3

[0094] Figure 9 It is a block diagram showing the configuration of a car navigation device to which the car-mounted display device according to Embodiment 3 of the present invention is applied. exist Figure 9 In the car navigation device 1B shown, the structure for realizing the navigation function and the structure for realizing the function of the car-mounted display device according to the third embodiment are the same as those described in the above-mentioned first embodiment. figure 2 Basically the same, but the difference is that the vehicle speed measuring part 19 is set to replace figure 2 The vehicle information acquisition unit 13 in the shown structure. The vehicle speed measurement unit 19 is a component that measures the vehicle speed of the vehicle on which the car navigation device 1B is mounted.

[0095] The determination unit 12 in Embodiment 3 sets the display type according to whether the host vehicle is running or parked. Based on the vehicle speed ...

Abstract

A vehicle-mounted display device is provided with character string tables in which a plurality of sets of screen data defining a plurality of screen designs including display boxes with the same size for displaying a character string, sets of font data relating to a plurality of types of font, and character strings to be displayed on the screen of each screen design defined by data relating to a plurality of types of screens are registered, which are provided for the respective sets of font data relating to the types of font, and in which the expressions of character strings are varied depending on the character size defined by the font data so that the character strings are displayed within the display box. An identifying unit (12) identifies the type of display used for the screen displayed on a display unit, and a screen using the screen data, font data, and character strings corresponding to the type of display identified by the identifying unit (12) is displayed on the display unit (6).

Description

technical field [0001] The present invention relates to a vehicle-mounted display device for displaying information on, for example, a display screen of a vehicle-mounted device or a display frame of an instrument panel. Background technique [0002] Generally, in-vehicle devices such as car navigation or car audio are designed so that one type of in-vehicle device can be loaded in multiple vehicles. Under such circumstances, it is desirable for both the in-vehicle device manufacturer and the automobile manufacturer that a single type of in-vehicle device can be applied to as many types of vehicles as possible. [0003] From the viewpoint of in-vehicle equipment manufacturers, the reason is as follows. They worry that if there are many types of in-vehicle equipment, manufacturing management will become complicated with the increase in types, and management costs will increase. In addition, from the viewpoint of automobile manufacturers, they worry that if dedicated in-vehic...
