Abstract

A drive controller for controlling to change the orientation of a display surface of a display in accordance with the seating position of occupants aboard a vehicle. A display unit is rotatably mounted on a vehicle. A controller automatically rotates the display unit to a first position where the display surface is oriented toward a driver seat, when an occupant is seated solely in the driver seat. The controller rotates the display unit to a third position where the display surface is oriented toward a front passenger seat, when an occupant is seated solely in the front passenger seat. The controller rotates the display unit to a second position where the display surface is oriented toward the middle point between the driver seat and the front passenger seat, on detecting both of the occupants are seated respectively in the driver seat and the front passenger seat.

Claims

1. A drive controller, comprising:

a display, mounted on a vehicle, having a display surface;

a drive device for driving the display to change the orientation of the display surface;

a seating position detector for detecting seating position of one or more occupants aboard the vehicle; and

a controller for controlling the drive device so as to orient the display surface in accordance with the seating position of the one or more occupants.

2. The drive controller according to claim 1,

wherein

the seating position detector is capable of detecting seating of the occupant in a driver seat and a front passenger seat respectively;

the drive device is capable of driving the display to a first position, a second position and a third position, the first position where the display surface is oriented toward the occupant seated in the driver seat, the second position where the display surface is oriented toward both of the occupants seated in the driver seat and the front passenger seat, the third position where the display surface is oriented toward the occupant seated in the front passenger seat;

the controller controls the drive device to drive the display to the first position when the seating position detector detects seating of the occupant in the driver seat and does not detect seating of the occupant in the front passenger seat;

the controller controls the drive device to drive the display to the second position when the seating position detector detects seating of the occupants both in the driver seat and in the front passenger seat; and

the controller controls the drive device to drive the display to the third position when seating position detector detects seating of the occupant in the front passenger seat and does not detect seating of the occupant in the driver seat.

3. A control method for controlling an orientation of a display surface of a display, comprising:

detecting the seating position of one or more occupants aboard the vehicle; and
