Abstract

In a vehicle display device equipped with a display on which a plurality of display zones is displayed, a user inputs through an operation lever a pointer moving request to move a pointer and a zone selection request to select another display zone as a selected display zone. An interface control part selects a reaction force map corresponding to the selected display zone after completion of the zone selection request from reaction force maps generated every display zone and stored in advance. Each reaction force map corresponds to each display zone and contains information of a reaction force corresponding to the position information of the button on the display zone. A reaction force supplying part supplies the reaction force to the operation lever on the basis of the selected reaction force map when the position of the pointer is overlapped with the button by the pointer moving request.

Claims

1. A vehicle display device comprising:

a display device equipped with a display mounted to a motor vehicle, a plurality of display zones being displayed on the display, and buttons being displayed on the display zones through which a user inputs operation instruction to control various types of operation regarding the motor vehicle;

an input means through which the user inputs a pointer moving request and a zone selection request, the pointer moving request being an instruction to move a position of a pointer displayed on the display in order to select the buttons, and the zone selection request being an instruction to select a new display zone as a selected display zone from the plurality of the display zones, the user selecting the button displayed on the selected display zone when the user moves the pointer onto the selected display zone;

a reaction force map storage means configured to store a reaction force map which being generated per display zone in advance, the reaction force map determining a reaction force to be supplied to the operation means on the basis of the position information of the button in the selected display zone;

a reaction force map selection means configured to select the reaction force map from a plurality of the reaction force maps so that the selected reaction force map corresponds to the selected display zone when the selected display zone is switched by the zone selection request; and

a reaction force supplying means configured to supply the reaction force to the input means on the basis of the selected reaction force map corresponding to the selected display zone when the pointer is overlapped with the selected display zone, on the basis of the pointer moving request to the pointer, with the button displayed on the selected display zone after completion of the selection of the display zone by the zone selection request.

2. The vehicle display device according to claim 1, further comprising an image generation means configured to generate the buttons per display zone, wherein the buttons are generated on the respective display zone by the corresponding image generation means,

wherein the reaction force supplying means receives the position information of the button displayed on the display zone transferred from the corresponding image generation means, and stores the reaction force map corresponding to the position information of each button for every display zone in advance.

3. The vehicle display device according to claim 1, wherein when the input means inputs the pointer moving request of moving the pointer to a boundary part between the selected display zone and the other display zone which is adjacent to the selected display zone, and the input means inputs the zone selection request to select another display zone as the selected display zone.

4. The vehicle display device according to claim 1, wherein each of the reaction force maps has the same resolution of the position information of each button.

5. The vehicle display device according to claim 1, wherein the input means is a joystick equipped with an operation lever which is deflected by the user, and the reaction force supplying means supplies a reaction force to the operation lever of the joystick in a direction which is opposite to the direction to which the user deflects the operation lever of the joystick.
