Abstract

A driver assistance system for driver assistance for consumption controlled driving combines tactile and visual feedback functions, especially in the form of a drive configuration, a display concept and/or a deceleration assistant, wherein the emphasis is, on the one hand, on a modified accelerator pedal characteristic and, on the other hand, on the ECO tips for interactive output of efficient driving instructions.

First claim

What is claimed is:

1. A driver assistance system for assisting a driver in achieving consumption-controlled driving, the driver assistance system comprising:
an electronic control system; and
a display operatively coupled with the electronic control system and providing a visual feedback function for the driver, wherein
in at least one defined economical driving mode, the electronic control system is operatively configured to display at least one of an interactive efficiency-based evaluation and recommendation of a current driving style of the driver on the display instead of a conventional fuel consumption display, and
the interactive efficiency-based evaluation is an efficiency range that is provided on the display, the efficiency range being indicative of a range of accelerator pedal angles.

2. The driver assistance system according to claim 1 , wherein the efficiency range is bar-shaped and continuously visible, when the current driving style of the driver is efficient and/or is following or has followed a recommendation, the bar-shaped efficiency range being visually highlighted.

3. A driver assistance system for assisting a driver in achieving consumption-controlled driving, the driver assistance system comprising:
an electronic control system; and
a display operatively coupled with the electronic control system and providing a visual feedback function for the driver, wherein
in at least one defined economical driving mode, the electronic control system is operatively configured to display at least one of an interactive efficiency-based evaluation and recommendation of a current driving style of the driver on the display,
the display provides a continuously visible efficiency range, when the current driving style of the driver is efficient and/or is following or has followed a recommendation, the continuously visible efficiency range being visually highlighted, and
the continuously visible efficiency range being indicative of a range of accelerator pedal angles.

4. The driver assistance system according to claim 1 , wherein at least one of an arrow, a symbol, and text information is additionally displayed on the display as a recommendation until the driver follows or has followed the recommendation.

5. The driver assistance system according to claim 3 , wherein at least one of an arrow, a symbol, and text information is additionally displayed on the display as a recommendation until the driver follows or has followed the recommendation.

6. The driver assistance system according to claim 1 , wherein
the range of accelerator pedal angles is an accelerator pedal characteristic-based efficiency range,
the efficiency range is bar-shaped, and
a marker is provided on the bar-shaped efficiency range, the marker being indicative of a current accelerator pedal angle in the accelerator pedal characteristic-based efficiency range, the indication being independent of any highlighting of the marker.

7. The driver assistance system according to claim 3 , wherein
the range of accelerator pedal angles is an accelerator pedal characteristic-based efficiency range,
the continuously visible efficiency range is bar-shaped, and
a marker is provided on the bar-shaped continuously visible efficiency range, the marker being indicative of a current accelerator pedal angle in the accelerator pedal characteristic-based efficiency range, the indication being independent of any highlighting of the marker.

8. The driver assistance system according to claim 6 , wherein a bar-shaped dynamic range is provided on the display to the right of the bar-shaped efficiency range, said bar-shaped dynamic range not being highlighted in any case; and
wherein the marker for representing the current accelerator pedal angle is provided in the bar-shaped dynamic range only if the accelerator pedal angle is located in an accelerator pedal characteristic-based dynamic range assigned to the bar-shaped dynamic range.

9. The driver assistance system according to claim 7 , wherein a bar-shaped dynamic range is provided on the display to the right of the bar-shaped continuously visible efficiency range, said bar-shaped dynamic range not being highlighted in any case; and
wherein the marker for representing the current accelerator pedal angle is provided in the bar-shaped dynamic range only if the accelerator pedal angle is located in an accelerator pedal characteristic-based dynamic range assigned to the bar-shaped dynamic range.

10. The driver assistance system according to claim 6 , wherein a bar-shaped recuperation range is provided on the display to the left of the bar-shaped efficiency range; and
wherein in an overrun mode of an internal combustion engine of the vehicle, the bar-shaped recuperation range is highlighted along with the bar-shaped efficiency range in order to indicate an increase in energy.

11. The driver assistance system according to claim 7 , wherein a bar-shaped recuperation range is provided on the display to the left of the bar-shaped continuously visible efficiency range; and
wherein in an overrun mode of an internal combustion engine of the vehicle, the bar-shaped recuperation range is highlighted along with the bar-shaped continuously visible efficiency range in order to indicate an increase in energy.

12. The driver assistance system according to claim 8 , wherein a bar-shaped recuperation range is provided on the display to the left of the bar-shaped efficiency range; and
wherein in an overrun mode of an internal combustion engine of the vehicle, the bar-shaped recuperation range is highlighted along with the bar-shaped efficiency range in order to indicate an increase in energy.

13. The driver assistance system according to claim 9 , wherein a bar-shaped recuperation range is provided on the display to the left of the bar-shaped continuously visible efficiency range; and
wherein in an overrun mode of an internal combustion engine of the vehicle, the bar-shaped recuperation range is highlighted along with the bar-shaped continuously visible efficiency range in order to indicate an increase in energy.

14. The driver assistance system according to claim 1 , wherein the display further comprises an additional reference field for recommending a plurality of economical driving styles; and
wherein for each recommended driving style at least one symbol, text instruction, and text information is provided in succession in the additional reference field.

15. The driver assistance system according to claim 3 , wherein the display further comprises an additional reference field for recommending a plurality of economical driving styles; and
wherein for each recommended driving style at least one symbol, text instruction, and text information is provided in succession in the additional reference field.

16. The driver assistance system according to claim 2 , wherein the electronic control system is operatively configured to activate a defined accelerator pedal characteristic as a driver configuration providing a tactile feedback function; and
wherein a first metering range of the defined accelerator pedal characteristic for an efficient driving style has a comparatively flat gradient, a second notification range for signaling a departure from the efficient driving style has a gradient change toward zero, and a third dynamic range with a comparatively steep gradient during which efficiency criteria are not being complied with; and
wherein only the first metering range in the form of the bar-shaped efficiency range and the third dynamic range in the form of a bar-shaped dynamic range are indicated on
