Abstract

A display device for a hybrid vehicle having a first drive source and at least one second drive source for driving the hybrid vehicle according to a load requirement by the driver. The display device has at least one display component for displaying a value of a load requirement predetermined by the driver at a specific time and, when the hybrid vehicle is driven exclusively by the at least one second drive at said time, at least one additional display component is provided for visualizing a limit of a maximum load requirement retrievable by the driver at said time, wherein if said load requirement is exceeded, the first drive source is also or exclusively activated for driving the hybrid vehicle. At least one further display component can be activated, via which the visualization of at least one such mode of operation of the hybrid vehicle is possible.

First claim

What is claimed is:

1. A display device for a hybrid vehicle having a first drive source and at least one second drive source of a different type than the first drive source for driving the hybrid vehicle in accordance with a load requirement from a driver, the display device comprising:
at least one first display component for displaying a value of a load requirement specified by the driver at a specific point in time, and, when the hybrid vehicle is driven exclusively by the at least one second drive source in a first operating mode at the specific point in time,
at least one second display component is provided for visualizing a limit of a maximum load requirement available for drawing by the driver in the first operating mode at this point in time, where exceeding this limit causes the first drive source for driving the hybrid vehicle to be activated in addition or exclusively;
at least one third display component being activatable with which it is possible to visualize a second operating mode of the hybrid vehicle in which the maximum load requirement available for drawing by the driver when the hybrid vehicle is driven exclusively by the at least one second drive source at the specific point in time is increased as compared to the first operating mode,
wherein the at least one second drive source is electric powered.

2. The display device according to claim 1 , wherein the first drive source is an internal combustion engine and the second drive source is an electric machine that can be operated as an electric motor.

3. The display device according to claim 1 , wherein the at least one first, second and third display components are each implemented or represented in the manner of a pointer.

4. The display device according to claim 3 , wherein the at least second and third display components are at least sometimes represented as a pointer that are discontinuous in the longitudinal direction.

5. A method for displaying, on a display device, values of a load requirement on a drive train of a hybrid vehicle having a first drive source and at least one second drive source of a different type than the first drive source for driving the hybrid vehicle, the method comprising:
displaying, by a first display component, a value of a load requirement specified by a driver at a specific point in time;
visualizing, when the hybrid vehicle is driven exclusively by the at least one second drive source in a first operating mode at this point in time, at least one limit of a maximum load requirement available for drawing by the driver at the specific point in time, where exceeding this limit causes the first drive source for driving the hybrid vehicle to be activated in addition or exclusively and where the limit is displayed by a second display component; and
activating a visualization of a second operating mode of the hybrid vehicle in which the maximum load requirement available for drawing by the driver when the hybrid vehicle is driven exclusively by the at least one second drive source at the specific point in time is increased as compared to the first operating mode, a limit of the maximum load requirement of the second operating mode being displayed by a third display component.

6. The method according to claim 5 , wherein an internal combustion engine is used as the first drive source, and an electric machine that can be operated as an electric motor is used as the second drive source.

7. The method according to claim 5 , wherein a brief audible signal is output upon activation and/or deactivation of the second operating mode that increases the maximum load requirement that can be drawn.

8. The method according to claim 5 , wherein a brief visual signal is output upon activation and/or deactivation of the second operating mode that increases the maximum load requirement available.

9. The method according to claim 5 , wherein the visualization of the second operating mode that increases the maximum load requirement available for drawing only takes place after activation of the second operating mode.

10. The method according to claim 5 , wherein the visualization of the second operating mode that increases the maximum load requirement available for drawing takes place continuously.

11. The display device according to claim 1 , wherein a reversal in a graphical representation of the second and third display components takes place due to activation and/or deactivation of the second operating mode that increases the maximum load requirement available for drawing.

12. A hybrid vehicle having at least one display device according to claim 1 .

13. The display device according to claim 1 , wherein a position of the second and third display component is movable on the display device, such that the maximum load requirement indicated by the second and third display component is able to increase or decrease.

14. The display device according to claim 1 , wherein when the hybrid vehicle is in the first operating mode, the second display component is displayed in solid lines and the third display component is displayed in dashed lines and when the hybrid vehicle is in the second operating mode, the second display component is displayed in dashed lines and the third display component is displayed in solid lines.

15. The method according to claim 5 , wherein a position of the second and third display component is movable on the display device, such that the maximum load requirement indicated by the second and third display component is able to increase or decrease.

16. The method according to claim 5 , wherein when the hybrid vehicle is in the first operating mode, displaying the second display component in solid lines and displaying the third display component in dashed lines and when the hybrid vehicle is in the second operating mode, displaying the second display component in dashed lines and displaying the third display component in solid lines.

17. The method according to claim 5 , wherein the at least one second drive source is electric powered.
