Subsequently, the cursor is moved up / down or left / right by the identified movement direction and the movement amount from the identified cursor position (S407).

At this time, when the amount of movement in the direction of movement from the identified cursor position exceeds the range of the screen of the LCD panel unit 610 and the cursor comes to the edge of the screen, the cursor is moved while scrolling the screen of the LCD panel unit 610.

Thereafter, when the movement is completed (S408), the position of the new cursor is checked (S409), and the area of the confirmed position is controlled to be displayed to be distinguished from other regions (S410).

That is, when the controller detects a signal according to the rotation of the dial manipulation unit 620, the controller reads the rotation direction and the amount of rotation of the dial manipulation unit 620, and the read direction and the amount of rotation are determined by the movement direction of the cursor and After reading the specific driving control course details which are converted to the movement amount and located closest to the distance according to the movement amount from the position of the current cursor among the driving control courses located in this movement direction, the specific driving control course is read. The cursor is placed on the details and displayed to be distinguished from the details of other driving control courses.

In this case, the method for displaying the display to be distinguished from other driving control courses according to the position of the cursor reads the current position of the cursor and checks the display area of the driving control course details displayed at the read position. It is possible by controlling the LCD panel 610 so that the displayed area can be displayed brighter or darker than other areas.

On the other hand, in the above-described process, when the control unit determines that the read result according to the signal generated by the operation of the dial manipulation unit 620 is not a signal according to the rotation operation but a signal according to the pressing operation, the control unit displays the LCD panel 610 on the LCD panel 610. The position of the displayed cursor is checked and control is performed according to the details of the driving control course according to this position (S411) (S412).

In this case, the controller reads whether the option item exists in the driving control course where the cursor is located (S413), and if it is determined that the option item does not exist, displays the screen displaying the driving control courses as it is. Position the cursor (S417).

If it is determined that the option item exists in the operation control course where the cursor is located as a result of the reading, the details of the option items are extracted and displayed on the LCD panel 610 (S414).

Then, the user selects whether there is an item to change the contents among the option items displayed on the LCD panel 610 (S415). If the user selects that there is no option item to be changed, the screen is returned to display the driving control courses. Display to position the cursor (S418).

If it is selected that there is an option item whose content is to be changed, the selection menu of the option item is displayed in a down menu manner to position the cursor (S416) so that the user can change the content of the option item. .

Next, an embodiment of a display method of a down menu method according to an operation of the dial manipulation unit 620 will be described with reference to the accompanying drawings.
