Method for displaying the remaining range of a motor vehicle
First Claim
1. A method for displaying a remaining range of a motor vehicle using an information device of the motor vehicle including a device for determining a fill level of an energy storage unit of the vehicle, a computer for determining estimated values relating to the remaining range, and a graphical display device for displaying the remaining range, the method comprising the acts of:
- repeatedly determining estimated values relating to the remaining range of the motor vehicle based on the fill level of the energy storage unit and at least one additional state of the motor vehicle that influences the remaining range;
determining a first remaining-range value based on the estimated values and displaying the first remaining range value as a first display value by a first graphical element on the display device;
determining an updated second remaining-range value during the display of the first display value;
determining a difference in terms of amount between the first remaining-range value and the updated second remaining range value;
if the difference exceeds a predetermined threshold value, displaying the second remaining-range value as a second display value by a second graphical element in addition to the first display value on the display device;
determining an updated third remaining range value during the display of the first display value and the second display value; and
if the updated third remaining-range value is closer to the second remaining-range value than to the first remaining-range value, accepting the second remaining-range value as the first display value and displaying the second remaining-range value by the first graphical element.

Abstract
A method displays the remaining range of a motor vehicle. The method determines repeatedly estimated values relating to the remaining range of the motor vehicle based on a fill level of an energy storage unit and at least one additional motor-vehicle state influencing the remaining range. A first remaining-range value is determined based on the estimated values and displayed as a first display value by a first graphical element on the display device. An updated second remaining-range value is determined during the display of the first display value. If the difference, in terms of amount, between the first and the second remaining-range values exceeds a predetermined threshold value, the second remaining-range value is displayed as a second display value by a second graphical element in addition to the first display value on the display device.

6. A method for displaying a remaining range of a motor vehicle using an information device of the motor vehicle including a device for determining a fill level of an energy storage unit of the vehicle, a computer for determining estimated values relating to the remaining range, and a graphical display device for displaying the remaining range, the method comprising the acts of:
-
repeatedly determining estimated values relating to the remaining range of the motor vehicle based on the fill level of the energy storage unit and at least one additional state of the motor vehicle that influences the remaining range; determining a first remaining-range value based on the estimated values and displaying the first remaining range value as a first display value by a first graphical element on the display device; determining an updated second remaining-range value during the display of the first display value; determining a difference in terms of amount between the first remaining-range value and the updated second remaining range value; if the difference exceeds a predetermined threshold value, displaying the second remaining-range value as a second display value by a second graphical element in addition to the first display value on the display device; during the display of the first display value and before the display of the second display value, monitoring a change of the at least one additional state of the motor vehicle that influences the remaining range; and if a remaining-range change in terms of amount resulting from the change of the state of the motor vehicle exceeds a predetermined change threshold value, displaying a third graphical element representing the remaining-range change in addition to the first display value. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14)

15. A method for displaying a remaining range of a motor vehicle on a display device, the method comprising the acts of:
-
repeatedly determining estimated values indicative of a remaining-range of the motor vehicle as a function of a consumable quantity stored in the vehicle and an additional state of the motor vehicle that influences the remaining-range; displaying a first graphical element on the display device, the first graphical element being indicative of a first remaining-range value determined based on the estimated values; during the display of the first graphical element, determining an updated second remaining-range value; if a difference in terms of amount between the first and the second remaining-range values exceeds a predetermined threshold value, displaying a second graphical element in addition to the first graphical element, the second graphical element being indicative of the second remaining range value; determining an updated third remaining-range value while displaying the first and second graphical elements; and if the third remaining-range value is closer to the second remaining-range value than to the first remaining-range value, displaying the second remaining-range value through the first graphical element. - View Dependent Claims (16, 17)

18. A method for displaying a remaining range of a motor vehicle on a display device, the method comprising the acts of:
-
repeatedly determining estimated values indicative of a remaining-range of the motor vehicle as a function of a consumable quantity stored in the vehicle and an additional state of the motor vehicle that influences the remaining-range; displaying a first graphical element on the display device, the first graphical element being indicative of a first remaining-range value determined based on the estimated values; during the display of the first graphical element, determining an updated second remaining-range value; if a difference in terms of amount between the first and the second remaining-range values exceeds a predetermined threshold value, displaying a second graphical element in addition to the first graphical element, the second graphical element being indicative of the second remaining range value; monitoring for a change of the additional state of the motor vehicle during the display of the first and second graphical elements; and if a remaining-range change resulting from the monitored change of the state of the motor vehicle exceeds a predetermined change threshold value, displaying a third graphical element indicative of the remaining-range change in addition to the first graphical element.
