Abstract

Drive unit for a vehicle including at least one drive wheel, the drive unit having an internal combustion engine, and, between the internal combustion engine and the at least one drive wheel, a clutch for transmitting a torque between the internal combustion engine and the drive wheel, as well as a vehicle control for controlling or regulating the internal combustion engine as a function of the speed of the clutch on the side of the internal combustion engine and/or as a function of the speed of the clutch on the side of the drive wheel.

Claims

1. A method for operating a drive unit (16) for a vehicle, including at least one drive wheel (8, 9), the drive unit (16) having an internal combustion engine (1) and having, situated between the internal combustion engine (1) and the at least one drive wheel (8, 9), a clutch (2) for transmitting a torque between the internal combustion engine (1) and the drive wheel (8, 9), wherein the internal combustion engine (1) is controlled or regulated as a function of the speed of the clutch (2) on the side of the internal combustion engine (1) and/or as a function of the speed of the clutch (2) on the side of the drive wheel (8, 9).

2. The method as recited in claim 1, wherein the internal combustion engine (1) is controlled or regulated as a function of the time derivative of the speed of the clutch (2) on the side of the internal combustion engine (1) and/or as a function of the time derivative of the speed of the clutch (2) on the side of the drive wheel (8, 9).

3. The method as recited in claim 1 or 2, wherein a setpoint value for the torque of the internal combustion engine (1) is determined as a function of the speed of the clutch (2) on the side of the internal combustion engine (1) and/or as a function of the speed of the clutch (2) on the side of the drive wheel (8, 9).

5. The method as recited in claim 2, 3, or 4, wherein a setpoint value for the torque of the internal combustion engine (1) is determined as a function of the time derivative of the speed of the clutch (2) on the side of the internal combustion engine (1) and/or as a function of the time derivative of the speed of the clutch (2) on the side of the drive wheel (8, 9).

6. The method as recited in claim 3 or 5, wherein the internal combustion engine (1) is controlled or regulated as a function of the setpoint value.

7. The method as recited in one of the preceding claims, wherein the torque of the internal combustion engine (1) is restricted and/or the setpoint value is a maximum value that is not to be exceeded.

8. The method as recited in one of the claim 2 through 6, wherein the torque of the internal combustion engine (1) is restricted when

9. The method as recited in claim 8, wherein the restriction of the torque of the internal combustion engine (1) is ended when

10. A drive unit (16) for a vehicle, including at least one drive wheel (8, 9), in particular a drive unit (16) operable according to a method as recited in one of the preceding claims, the drive unit (16) having an internal combustion engine (1) and having, situated between the internal combustion engine (1) and the at least one drive wheel (8, 9), a clutch (2) for transmitting a torque between the internal combustion engine (1) and the drive wheel (8, 9), wherein the drive unit (16) has a vehicle control (15) for controlling or regulating the internal combustion engine (1) as a function of the speed of the clutch (2) on the side of the internal combustion engine (1) and/or as a function of the speed of the clutch (2) on the side of the drive wheel (8, 9).

11. A drive unit (16) for a vehicle, including at least one drive wheel (8, 9), in particular a drive unit (16) operable according to a method as recited in one of the preceding claims, the drive unit (16) having an internal combustion engine (1) and having, situated between the internal combustion engine (1) and the at least one drive wheel (8, 9), a clutch (2) for transmitting a torque between the internal combustion engine (1) and the drive wheel (8, 9), wherein the drive unit (16) has a vehicle control (15) for controlling or regulating the internal combustion engine (1) as a function of the time derivative of the speed of the clutch (2) on the side of the internal combustion engine (1) and/or as a function of the time derivative of the speed of the clutch (2) on the side of the drive wheel (8, 9).

12. A vehicle control (15) for a vehicle, including at least one drive wheel (8, 9) and a drive unit (16), in particular a drive unit (16) operable according to a method as recited in one of claims 1 through 9, the drive unit (16) having an internal combustion engine (1) and having, situated between the internal combustion engine (1) and the at least one drive wheel (8, 9), a clutch (2) for transmitting a torque between the internal combustion engine (1) and the drive wheel (8, 9), wherein the vehicle control (15) is configured for controlling or regulating the internal combustion engine (1) as a function of the speed of the clutch (2) on the side of the internal combustion engine (1) and/or as a function of the speed of the clutch (2) on the side of the drive wheel (8, 9).

13. The vehicle control (15) for a vehicle, including at least one drive wheel (8, 9) and a drive unit (16), in particular a drive unit (16) operable according to a method as recited in one of claims 1 through 9, the drive unit (16) having an internal combustion engine (1) and having, situated between the internal combustion engine (1) and the at least one drive wheel (8, 9), a clutch (2) for transmitting a torque between the internal combustion engine (1) and the drive wheel (8, 9), wherein the vehicle control (15) is configured for controlling or regulating the internal combustion engine (1) as a function of the time derivative of the speed of the clutch (2) on the side of the internal combustion engine (1) and/or as a function of the time derivative of the speed of the clutch (2) on the side of the drive wheel (8, 9).

4. A method for operating a drive unit (16) for a vehicle, including at least one drive wheel (8, 9), the drive unit having an internal combustion engine (1) and having, situated between the internal combustion engine (1) and the at least one drive wheel (8, 9), a clutch (2) for transmitting a torque between the internal combustion engine (1) and the drive wheel (8, 9), wherein the internal combustion engine (1) is controlled or regulated as a function of the time derivative of the speed of the clutch (2) on the side of the internal combustion engine (1) and/or as a function of the time derivative of the speed of the clutch (2) on the side of the drive wheel (8, 9).
