Abstract

A method for operating a transmission device for a motor vehicle. A driving gear is selected from a quantity of driving gears and set to the transmission. At the same time, in a normal operating state, the driving gear quantity is compiled from a specific number of driving gears contained in a total quantity of the driving gears, containing all of the driving gears. The driving gear quantity is compiled as a function of at least one state variable of the motor vehicle.

First claim

The invention claimed is:

1. A method for operating a transmission device for a motor vehicle, comprising:
a driving gear is selected from a driving gear quantity and set to a transmission, wherein in a normal operating mode, the driving gear quantity is compiled from a specified number of driving gears contained in a total driving gear quantity, wherein the total driving gear quantity contains all of the driving gears of the transmission, and wherein the driving gear quantity is compiled as a function of at least one state variable of the motor vehicle, and wherein the driving gear is selected independently from the compiling of the driving gear quantity.

2. The method according to claim 1 , wherein a smallest driving gear of the driving gear quantity is greater than a smallest driving gear of the total driving gear quantity.

3. The method according to claim 2 , wherein the smallest driving gear of the driving gear quantity corresponds to the driving gear following the smallest driving gear of the total driving gear quantity.

4. The method according to claim 2 , wherein the smallest driving gear of the driving gear quantity is designed as a start-up gear.

5. The method according to claim 1 , wherein the state variable is at least one of the driving gear that is currently set to the transmission, a selected driving program, a selected driving mode, an ambient temperature, an operating value of a trailer, an ambient air pressure, a geodetic height and a driver profile.

6. The method according to claim 1 , wherein when an accelerator pedal threshold value is exceeded by an accelerator pedal position, the normal operating mode is switched to an alternative operating mode in which the driving gear quantity corresponds to the total driving gear quantity.

7. The method according to claim 1 , wherein the compilation of the driving gear quantity is carried out when a driving speed of the motor vehicle is below a driving speed threshold.
