Abstract

When a CPU judges that a vehicle is stopped, a display image surrounded by a separator is displayed in such a first quality that a driver can watch while the display image is moving from a first display area to a second display area, and the motor is driven in a relatively low first speed to move the separator. When the CPU judges that the vehicle is running, the separator is rapidly moved and data about the vehicle such as warning is rapidly displayed.

Claims

1. A display apparatus for a vehicle comprising:

a display device for displaying data about the vehicle;

a display controller for controlling in such a way that according to a predetermined signal, a first data about the vehicle displayed on a first display area is shifted to a second display area, and a second data about the vehicle is displayed on the first display area;

a display separator surrounding the first data for separating the first data from the other data;

a movement controller for moving the separator synchronized with the first data by driving a motor connected to the separator through gears in predetermined speed and torque; and

a judging device for judging whether the vehicle is moving or stopping,

wherein when the judging device judges that the vehicle is stopping, the display controller controls that while the first data is moved from the first data area to the second data area, the first data is displayed in a first image quality which allows a driver to watch the first data, and the movement controller controls the motor in a first lower speed for moving the separator,

wherein when the judging device judges that the vehicle is moving, the display controller controls that while the first data is moved from the first data area to the second data area, the first data is displayed in a second image quality lower than the first image quality, and the movement controller controls the motor in a second higher speed for moving the separator.

2. The display apparatus for a vehicle as claimed in claim 1,

wherein when the vehicle is judged stopping, the motor is driven in a lower torque for moving the separator than when the vehicle is judged moving.

3. The display apparatus for a vehicle as claimed in claim 1,

further comprising a thermometer for detecting a temperature around the movement controller,

wherein when the thermometer detects such a low temperature that the separator couldn'"'"'t move smoothly, the movement controller controls that the motor is driven in a higher torque than when the thermometer detects more than such a low temperature.
