Abstract

An onboard display device includes multiple screen data that define plural types of screen designs including a character string display frame with equal size; plural types of font data; and multiple character string tables which record character strings to be displayed on a screen with one of the screen designs defined by the plural types of screen data, are each provided for one of the plural types of font data, and include character strings whose written forms are altered according to character size defined by the font data so that the character strings can be contained in the display frame, wherein the decision unit 12 decides a display type to be used for screen display on a display unit, and the display unit 6 displays the screen using the screen data, font data and character string corresponding to the display type decided by the decision unit 12.

First claim

What is claimed is:

1. An onboard display device comprising:
a screen data storage unit for storing a plurality of screen data that define plural types of screen designs including a character string display frame with equal size;
a font data storage unit for storing plural types of font data;
a character string table storage unit for storing a plurality of character string tables each of which is associated with different types of the font data, each of the character string tables having a character string which is common between the character string tables, the common character strings indicating a same meaning and differing from each other in number of characters;
a display unit for displaying a screen using the screen data, the font data and a character string in the character string tables;
a controller programed to execute a process based on a decision by the onboard display device of a display type which indicates a combination of the screen data, the font data and the character string in the character string tables to be used for screen display on the display unit, the process comprising:
acquiring the screen data corresponding to the decided display type from the screen data storage unit;
acquiring the font data corresponding to the decided display type from the font data storage unit;
acquiring the character string in the character string table corresponding to the decided display type from the character string table storage unit; and
controlling the display unit so as to display the acquired screen using the screen data, the acquired font data, and the acquired character string.

2. The onboard display device according to claim 1 , further comprising:
a data communication device connected to an onboard network to acquire model information about the vehicle via the network,
wherein the onboard display device:
has correspondence information in which a plurality of models of vehicles and display types matching the models are set; and
decides the display type matching the model of the vehicle as the display type to be used for the screen display of the display unit by referring to the correspondence information in accordance with the acquired model information.

3. The onboard display device according to claim 1 , further comprising:
an operation unit manipulated by a user to select a display type; and
a set value storage unit for storing a set value designating the display type selected via the operation unit, wherein
the display type designated by the set value stored in the set value storage unit is decided as the display type to be used for the screen display of the display unit.

4. The onboard display device according to claim 1 , further comprising:
a vehicle speed measuring unit for measuring a speed of the vehicle, wherein
different display types are decided as the display type to be used for the screen display of the display unit depending on whether the vehicle is moving or not.

5. The onboard display device according to claim 4 , wherein
when the vehicle is moving, a display type of the combination, which includes the font data that defines the character size that enables the character string to be contained in the display frame, is decided as the display type to be used for the screen display of the display unit; and
when the vehicle is not moving, a display type of the combination, which includes the font data that defines the character size that enables a written form of the character string to be altered so as to be contained in the display frame, is decided as the display type to be used for the screen display of the display unit.
