In-vehicle display apparatus

An in-vehicle display apparatus comprising:

• an operation device including an operation knob which moves according to a user's operation;
• and
• a display control device including a display section to display a display window,
• the in-vehicle display apparatus displaying in the display section a cursor in association with a position of the operation knob, the cursor being used for selecting a set button selectable in the display window,
• the operation device further including a force applying section configured for applying force to the operation knob according to an instruction from the display control device,
• the display control device further including a storage section and a force application instruction portion,
• the storage section being configured to store a map specifying that, with respect to the display window containing a set button display region to display a series of set buttons in a line, when the cursor moves over the series of set buttons contained in the set button display region in one direction, a strength of a vibration applied to the operation knob is varied step by step in the one direction over the set buttons,
• the force applying section being configured to
• obtain, from the storage section, the map corresponding to the display window displayed in the display section, and
• instruct the force applying section to change the strength of the vibration applied to the operation knob step by step in the one direction over the set buttons when the cursor moves over the series of set buttons contained in the set button display region in the one direction.

An in-vehicle display apparatus to be used with an in-vehicle display device including a display section to display a window, the in-vehicle display apparatus displaying in the display section a cursor, the cursor being used for selecting buttons selectable in the display section, comprising:

• an operation knob configured to
• move in accordance with a user's operation, and
• control a position of the cursor displayed in the display section;
• a force applying section configured to apply a vibration and a reactive force to the operation knob, and
• a storage section configured to store a map that specifies a plurality of degrees of the vibrations with respect to a plurality of buttons displayed in the display section, wherein:
• a degree of the vibration specified to a button for a maximum value is larger than a degree of the vibration specified to a button for a minimum value;
• when a user operates the operation knob to move the cursor to an adjacent button, the force applying section applies a predetermined fixed reactive force to the operation knob;
• and
• when the operation knob is settled on a selected button by the user's operation, the force applying section applies the vibration to the operation knob in accordance with a degree of the vibration with respect to the selected button among the plurality of degrees of the vibrations specified by the map stored in the storage section.
