Abstract

In a method for informing a driver of a vehicle about a capability of an electric motor in the vehicle to output a minimum power able to be requested by the driver, a variable display of a display element is implemented depending upon whether the requestable minimum power is able to be provided by the electric motor over a specifiable period of time.

Claims

1-8. -8. (canceled)

9. A method for informing a driver of a vehicle about a capability of an electric motor in the vehicle to output a minimum power able to be requested by the driver, comprising:

providing a variable display of a display element depending upon whether the minimum power is able to be provided by the electric motor over a first specified period of time.

10. The method as recited in claim 9, wherein the display element is displayed as a function of a period of time over which the minimum power is able to be provided at the maximum by the electric motor.

11. The method as recited in claim 10, wherein the period of time over which the minimum power is able to be provided at the maximum by the electric motor is displayed.

12. The method as recited in claim 9, wherein the minimum power is able to be requested through an input by the driver only when the minimum power is able to be provided at least over the specified period of time.

13. The method as recited in claim 12, wherein (a) if at a first point in time at which the minimum power is requested by the driver, the minimum power is able to be provided at the maximum over a period of time which is shorter than the specified period of time, and (b) if at a subsequent second point in time, the period of time over which the minimum power is able to be provided at the maximum is at least equal to the specified period of time, indicating condition (b) to the driver.

14. The method as recited in claim 12, wherein in the event that while the minimum power is being provided, the period of time over which the minimum power is able to be provided at the maximum by the electric motor falls short of a second specified period of time, providing an indication of the existence of the shortfall to the driver.

15. A control device for controlling a display unit to inform a driver of a vehicle about a capability of an electric motor in the vehicle to output a minimum power able to be requested by the driver, comprising:

an arithmetic logic unit;

a first interface to the display unit; and

a second interface to an energy accumulator of the electric motor of a vehicle;

wherein the control device controls the display unit to provide a variable display of a display element depending upon whether the minimum power is able to be provided by the electric motor over a specified period of time.

16. The control device as recited in claim 15, further comprising:

a third interface to an input unit for the driver to request the minimum power from the electric motor.
