Abstract

A travel route display device ( 1 ) includes a display unit ( 130 ), a topographical data storage unit ( 110 b ) that stores three-dimensional topographical data, a travel data storage unit ( 110 c ) that stores travel data relating to a travel route of a vehicle and a driving status of the vehicle on the travel route, and a control unit ( 120 ) that, when displaying the topographical data stored in the topographical data storage unit ( 110 b ) on the display unit ( 130 ), simultaneously displays, on the display unit ( 130 ), the travel route indicated by the travel data stored in the travel data storage unit ( 110 c ) in a display mode that corresponds to the driving status.

First claim

What is claimed is:

1. A travel route display device comprising:
a display unit;
a topographical data storage unit that stores three-dimensional topographical data;
a travel data storage unit that stores travel data relating to a travel route of a vehicle and a driving status of the vehicle on the travel route, wherein the travel data includes, in association with a position of the vehicle, at least two selected from: a speed of the vehicle, an acceleration of the vehicle, or a gradient of the vehicle as the driving status; and
a control unit that, when displaying the topographical data stored in the topographical data storage unit on the display unit while the vehicle is driving, simultaneously displays, on the display unit, the travel route indicated by the travel data stored in the travel data storage unit in a display mode that corresponds to the driving status, wherein the control unit, when displaying the travel route, changes the display mode in accordance with a change of at least two selected from: the speed of the vehicle, the acceleration of the vehicle, or the gradient of the vehicle, and wherein the control unit, when displaying the travel route, draws the travel route as a line or dots, and the control unit sets: a width of the line of a portion where at least two selected from the speed, gradient or acceleration are equal to or greater than prescribed values to be wider, a thickness of the line of the portion to be greater, or a size of the dots of the portion to be larger than those of other portions.

2. The travel route display device according to claim 1 , wherein the control unit draws the travel route as a line, and changes a width of the line on the travel route based on the driving status.

3. The travel route display device according to claim 2 , wherein the control unit, when displaying the travel route, adds information that indicates an advancement direction of the vehicle.

4. The travel route display device according to claim 2 , wherein the control unit, when displaying the travel route, causes a display mode for a section in which the driving status is within a range of a prescribed value to be different from a display mode for another section.

5. The travel route display device according to claim 1 , wherein the control unit draws the travel route as a line having a three-dimensional thickness in a direction perpendicular to the travel route, and changes the thickness based on the driving status.

6. The travel route display device according to claim 5 , wherein the control unit, when displaying the travel route, adds information that indicates an advancement direction of the vehicle.

7. The travel route display device according to claim 5 , wherein the control unit, when displaying the travel route, causes a display mode for a section in which the driving status is within a range of a prescribed value to be different from a display mode for another section.

8. The travel route display device according to claim 1 , wherein the control unit draws the travel route as a dotted line that includes a plurality of dots, and changes a size of the dots included in the dotted line based on the driving status.

9. The travel route display device according to claim 8 , wherein the control unit, when displaying the travel route, adds information that indicates an advancement direction of the vehicle.

10. The travel route display device according to claim 8 , wherein the control unit, when displaying the travel route, causes a display mode for a section in which the driving status is within a range of a prescribed value to be different from a display mode for another section.

11. The travel route display device according to claim 1 , wherein the control unit, when displaying the travel route, adds information that indicates an advancement direction of the vehicle.

12. The travel route display device according to claim 1 , wherein the control unit, when displaying the travel route, causes a display mode for a section in which the driving status is within a range of a prescribed value to be different from a display mode for another section.

13. A non-transitory travel route display program allowing a computer to execute the steps of:
acquiring three-dimensional topographical data from a topographical data storage unit that stores the topographical data;
acquiring travel data relating to a travel route of a vehicle and a driving status of the vehicle on the travel route from a travel data storage unit that stores the travel data, wherein the travel data includes, in association with a position of the vehicle, at least two selected from: a speed of the vehicle, an acceleration of the vehicle, or a gradient of the vehicle as the driving status;
when displaying the topographical data on a display unit while the vehicle is driving, simultaneously displaying, on the display unit, the travel route indicated by the travel data stored in the travel data storage unit in a display mode that corresponds to the driving status;
when displaying the travel route, changing the display mode in accordance with a change of at least two selected from: the speed of the vehicle, the acceleration of the vehicle, or the gradient of the vehicle; and
when displaying the travel route, drawing the travel route as a line or dots and setting: a width of the line of a portion where at least two selected from the speed, gradient or acceleration are equal to or greater than prescribed values to be wider; a thickness of the line of the portion to be greater; or a size of the dots of the portion to be larger than those of other portions.

14. A travel route display device comprising:
a display unit;
a topographical data storage unit that stores three-dimensional topographical data;
a travel data storage unit that stores travel data relating to a travel route of a vehicle and a driving status of the vehicle on the travel route, wherein the travel data includes, in association with a position of the vehicle, at least two selected from: a speed of the vehicle, an acceleration of the vehicle, or a gradient of the vehicle as the driving status; and
a control unit that, when displaying the topographical data stored in the topographical data storage unit on the display unit while the vehicle is driving, simultaneously displays, on the display unit, the travel route indicated by the travel data stored in the travel data storage unit in a display mode that corresponds to the driving status, wherein the control unit, when displaying the travel route, changes the display mode in accordance with a change of at least two selected from: the speed of the vehicle, the acceleration of the vehicle, or the gradient of the vehicle, wherein the control unit, when displaying the travel route, draws the travel route as a line or dots, and the control unit sets: a width of the line of a portion where at least two selected from the speed, gradient or acceleration are equal to or greater than prescribed values to be wider, a thickness of the line of the portion to be greater, or a size of the dots of the portion to be larger than those of other portions; and wherein the control unit sets the width of the line, the thickness of the line, or the size of the dots to increase as an amount of deviation from the prescribed value increases.

15. A travel route display device comprising:
a display unit;
a topographical data storage unit that stores three-dimensional topographical data;
a travel data storage unit that stores travel data relating to a travel route of a vehicle and a driving status of the vehicle on the travel route, wherein the travel data includes, in associat
