Abstract

A motor vehicle, in particular a passenger motor vehicle, has a drive train which has a drive assembly, at least one gear mechanism and a plurality of drive axles. The drive train has at least one transverse lock for locking a rotational speed equalization between wheels of one drive axle and at least one longitudinal lock for locking a rotational speed equalization between two drive axles. A torque distribution of the drive train, namely a torque distribution between the drive axles of the drive train and/or a torque distribution between the wheels of the drive axles, can be determined and visualized for a driver.

Claims

1. A motor vehicle, including passenger motor vehicles, comprising:

at least one drive train having a drive assembly, at least one gear mechanism and a plurality of drive axles with wheels, said drive train further having at least one transverse lock for locking a rotational speed equalization between said wheels of one of said drive axles and at least one longitudinal lock for locking a rotational speed equalization between two of said drive axles; and

a display receiving information from said drive train for determining and visualizing a torque distribution of said drive train, said display visualizing to a driver at least one of the torque distribution between said drive axles of said drive train and the torque distribution between said wheels of said drive axles.

2. The motor vehicle according to claim 1, wherein said drive train has two of said drive axles, and at least one of the torque distribution between said two drive axles and the torque distribution between said wheels of said drive axles can be determined and visualized.

3. The motor vehicle according to claim 1, wherein the torque distribution is visualized as a pictogram on said display, said pictogram showing at least said drive axles of said drive train and, next to said drive axles, a torque ratio between a torque present at said respective drive axle and an overall torque.

4. The motor vehicle according to claim 1, wherein the torque distribution is visualized as a pictogram on said display, said pictogram showing at least said drive axles of said drive train together with said wheels assigned to said drive axles and, next to said wheels, a torque ratio between a torque present at said respective wheel and an overall torque.

5. The motor vehicle according to claim 3, wherein said torque ratio is visualized graphically at least as one of bars, columns, numerically as numbers, and numerically as percentages.

6. The motor vehicle according to claim 4, wherein said torque ratio is visualized graphically at least as one of bars, columns, numerically as numbers, and numerically as percentages.

7. The motor vehicle according to claim 1, wherein said display visualizes at least one determined longitudinal lock value corresponding to a maximum possible proportion of a nominal torque of a lock which can be routed to one of said drive axles.

8. The motor vehicle according to claim 1, wherein said display visualizes at least one determined transverse lock value corresponding to a maximum possible proportion of a nominal torque of a lock which can be routed to one of said drive axles.
