Abstract

Each of an accelerator operation amount and a brake operation amount is displayed as an amount of displacement in the same direction (same side) from a reference position. Also, respective boundaries (or ranges) are displayed in the same direction for determining whether or not the accelerator operation amount during accelerator operation is in a fuel efficient region and whether or not the brake operation amount during the brake operation is in the fuel efficient region. With such a configuration, respective target positions (positions of the respective boundaries (ranges) for determining the fuel efficient region) during accelerator operation and during brake operation are in the same side, thus a driver can operate the vehicle without confusion.

Claims

1. A display device for displaying a driving operation state of a vehicle by a driver,

wherein in response to an accelerator operation, an accelerator operation amount is displayed as an amount of displacement from a reference position in one direction, and a boundary or range is displayed at a position spaced apart from the reference position by a prescribed distance in the one direction such that the accelerator operation amount can be visually determined to be in a fuel efficient region, and

wherein in response to a brake operation, a brake operation amount is displayed as an amount of displacement from the reference position in the one direction, and a boundary or range is displayed at a position spaced apart from the reference position by a prescribed distance in the one direction such that the brake operation amount can be visually determined to be in the fuel efficient region.

2. The display device according to claim 1,

wherein during the accelerator operation, neither the brake operation amount nor the boundary or range for visually determining the brake operation amount being in the fuel efficient region is displayed.

3. The display device according to claim 1,

wherein during the brake operation, neither the accelerator operation amount nor the boundary or range for visually determining the accelerator operation amount being in the fuel efficient region is displayed.

4. The display device according to claim 1,

wherein both the boundary or range for visually determining the accelerator operation amount and the boundary or range for visually determining the brake operation amount are displayed at a position spaced apart from the reference position by the same distance.

5. The display device according to claim 1,

wherein the vehicle is an idle stop vehicle capable of performing an automatic engine stop based on the brake operation amount, and

wherein a display during the brake operation before the automatic engine stop is a display of a boundary or range for visually determining whether or not the brake operation amount is in an automatic engine stop permission range.

6. The display device according to claim 1,

wherein the vehicle is an idle stop vehicle capable of performing an automatic engine start based on the brake operation amount, and

wherein a display of the brake operation amount during the automatic engine stop is a display of a boundary or range for visually determining whether or not the brake operation amount is in an automatic engine start permission range.

7. The display device according to claim 1,

wherein the vehicle is an idle stop vehicle capable of performing an automatic engine start based on the brake operation amount, and

wherein a display during the automatic engine stop is a display selected from the following three displays:

a display of a boundary or range for visually determining whether or not an electrical power use state is in an automatic engine stop continuable range;

a display of a boundary or range for visually determining whether or not an air conditioner use state is in the automatic engine stop continuable range; and

a display of a boundary or range for visually determining whether or not the brake operation amount is in an automatic engine start permission range.
