Abstract

A hybrid motor vehicle device with a data input unit, which has at least one operating element for a user input of at least one drive distance parameter, and with a calculating unit, which is provided to adapt a hybrid operating strategy to the at least one drive distance parameter. The calculating unit in at least one hybrid operating mode is provided to assign the at least one operating element to a destination-independent input function of the at least one drive distance parameter characterizing a predicted drive distance.

Claims

1. A hybrid motor vehicle device, comprising:

an internal combustion engine;

a battery device;

an electric motor, which is used as a sole drive source;

a data input unit, which has at least one operating element for a user input of at least one drive distance parameter; and

a calculating unit, which adapts a hybrid operating strategy, wherein the hybrid operating strategy controls activation of the internal combustion engine according to the at least one drive distance parameter,

wherein the calculating unit, in at least one operating mode, assigns a destination-independent input function as the at least one drive distance parameter characterizing a predicted drive distance.

2. A hybrid drive device according to claim 1, wherein the data input unit transmits a predicted drive distance to the calculating unit as the at least one drive distance parameter.

3. A hybrid drive device according to claim 1, wherein the calculating unit has at least a first and a second hybrid operating mode and the data input unit allows selection of the hybrid operating modes.

4. A hybrid drive device according to claim 3, wherein the first hybrid operating mode is a long distance hybrid operating mode in which the calculating unit provides the drive distance parameter depending on a charging state.

5. A hybrid drive device according to claim 4, wherein the calculating unit calculates a maximum purely electrical drive distance in the long distance hybrid operating mode and provides a multiple of the purely electrical drive distance as drive distance parameter.

6. A hybrid drive device according to claim 3, wherein the calculating unit assigns a selecting function for the direct selection of the first hybrid operating mode to the at least one operating element.

7. A hybrid drive device according to claim 6, wherein the at least one operating element is a key button.

8. A hybrid drive device according to claim 1, wherein the calculating unit assigns an input function for a drive distance desired by an operator to the at least one operating element.

9. A hybrid drive device according to claim 1, wherein the data input unit transmits an allowance for a purely electrical drive distance to the calculating unit as a further drive distance parameter.

10. A hybrid drive device according to claim 1, wherein the data input unit transmits a drive distance profile to the calculating unit as a further drive distance parameter.

11. A hybrid drive device according to claim 10, wherein the calculating unit assigns a destination-independent input function for the drive distance profile to the at least one operating element.

12. A hybrid drive device according to claim 3, wherein the calculating unit assigns a selection function for the direct selection of the second hybrid operating mode to the at least one operating element, wherein the calculating unit holds or increases a charging state.

13. A hybrid drive device according to claim 1, comprising:

a storage unit that stores at least one drive distance parameter set with at least one destination-independent drive distance parameter.

14. A hybrid drive device according to claim 13, wherein the calculating unit saves a driven distance data set in the storage unit.

16. A hybrid drive device according to claim 1, wherein the calculating unit is independent of a navigation unit.

17. A hybrid drive device according to claim 1, wherein the calculating unit has a short distance operating mode, in which it switches to a purely electrical drive mode.

18. A hybrid drive device according to claim 1, comprising:

a charging device that charges the battery device.

19. A method for a hybrid motor vehicle device that comprises an internal combustion engine, a battery device, an electric motor, which is used as the sole drive source, a data input unit and a calculating unit, the method comprising:

receiving, by at least one operating element of the data input unit, input of at least one drive distance parameter;

adapting, by the calculating unit, a hybrid operating strategy that controls activation of the internal combustion engine according to the at least one drive distance parameter; and

assigning, by the calculating unit in at least one operating mode, a destination-independent input function for the at least one drive distance parameter characterizing a predicted drive distance.
