Abstract

The vehicle-mounted display unit includes a display having a meter area and an auxiliary indication area. The meter area indicates a dial image for showing measured values of an operational condition of a motor vehicle. The auxiliary indication area indicates information other than the measured values. The display unit has a control device for controlling contents indicated on the display. The control device indicates a normal length pointer extended in the auxiliary indication area at a normal indication state, while the control device indicates a shorter length pointer in the auxiliary indication area when the other information is indicated.

Claims

1. A vehicle-mounted display unit, comprising:

a display having a meter area and an auxiliary indication area, the meter area indicating a dial image for showing measured values of an operational condition of a motor vehicle, and the auxiliary indication area indicating information other than the measured values; and

a control device for controlling contents indicated on the display,

wherein the control device selectively provides a normal indication or a maintenance indication in the auxiliary indication area, the normal indication including the dial image and a normal length pointer which extends into the auxiliary indication area, and the maintenance indication including an animation for maintenance of the vehicle, and

wherein the control device controls the display such that the maintenance indication includes a pointer shorter than the normal length pointer.

2. The display unit recited in claim 1, wherein a three-dimensional indication is applied to the animation.

3. A vehicle-mounted display unit, comprising:

a display having a meter area and an auxiliary indication area, the meter area indicating a dial image for showing measured values of an operational condition of a motor vehicle, and the auxiliary indication area indicating information other than the measured values; and

a control device for controlling contents indicated on the display,

wherein the control device displays a normal length pointer in the auxiliary indication area in a normal indication state and a shorter length pointer in the auxiliary indication area when the information other than the measured values is indicated.

4. The display unit recited in claim 3, wherein the control device changes the length of the pointer such that a distal end of the pointer is constant in a radial distance from a pivot of the pointer.

5. The display unit recited in claim 4, wherein the control device changes the length of the pointer from a longer length to a shorter length via an intermediate length.

6. The display unit recited in claim 3, wherein the control device displays the pointer with an afterimage positioned in a trailing side of the pointer when the pointer moves.
