Abstract

An in-vehicle display device is provided which includes a unit having a mounting portion and a display panel, a driving mechanism for moving the display panel, a status detection portion for detecting the status of on-vehicle equipment, and a control circuit for controlling the operation of the driving mechanism in response to a detection signal from the status detection portion. The mounting portion includes a housing for housing the display panel and is installed in the ceiling in a vehicle. The display panel has an upper end that is mounted, for rotation about a shaft, to the front end of the housing. The driving mechanism includes a motor and transmission portion for transmitting the power of the motor to the display panel. The status detection portion includes a gear sensor, a key sensor, a signal output portion, and an operation panel for operating the vehicle-mounted electronic equipment.

Claims

1. An in-vehicle display apparatus comprising:

a display portion having a screen for displaying video information, said display portion being mounted to a ceiling in a vehicle for movement between an open position, in which the screen of said display portion is viewable by at least one passenger, and a closed position, in which said display portion is housed in the ceiling and is not viewable by the passenger;

a driving mechanism for moving the display portion, said driving mechanism including a motor as a driving source for said driving mechanism;

status detection means for detecting the status of on-vehicle equipment and for sending a detection signal; and

control means for controlling the operation of said driving mechanism in response to the detection signal from said status detection means.

2. An in-vehicle display apparatus according claim 1, wherein:

said status detection means includes a gear status detection portion for detecting the gear status of the vehicle; and

said control means includes a reverse gear determination portion for determining that said status detection means detects a reverse gear operation, and a close operation instructing portion for outputting an instruction signal for operating the motor so as to cause said display portion to move to the closed position when the reverse gear determination portion determines the reverse gear operation.

3. An in-vehicle display apparatus according to claim 1 or 2, wherein:

said status detection means includes a key status detection portion for detecting the status of the ignition key of the vehicle; and

said control means includes a key determination portion for determining that said status detection means detects removal of the ignition key, and a close operation instructing portion for outputting an instruction signal for operating the motor so as to cause said display portion to move to the closed position when the key determination portion determines removal of the ignition key.

4. An in-vehicle display apparatus according to one of claims 1 to 3, wherein:

said status detection means includes an equipment status detection portion for detecting the status of vehicle-mounted electronic equipment; and

said control means includes an equipment status determination portion for determining that the equipment status detection portion detects a state in which no video needs to be displayed on the vehicle-mounted electronic equipment, and a close operation instructing portion for outputting an instruction signal for operating the motor so as to cause said display portion to move to the closed position when the equipment status determination portion determines the state in which no video needs to be displayed.

5. An in-vehicle display apparatus according to one of claims 1 to 4, further comprising operation means for entering an operation instruction, wherein said control means includes a close operation instructing portion for outputting an instruction signal for operating the motor so as to cause said display portion to move to the closed portion in response to the operation instruction from said operation means.

6. An in-vehicle display apparatus according to one of claims 2 to 5, wherein said control means includes an open operation instructing portion for outputting an instruction signal for operating the motor so as to cause said display portion to move to the open position when no instruction is inputted from said status detection means or said operations means.

7. An in-vehicle display apparatus according to one of claims 1 to 6, wherein said display portion includes a power circuit for supplying power thereto, and said control means includes a power supply switch portion for opening the power circuit when the close operation instructing portion outputs the instruction signal for operating the motor.
