Abstract
A method for operating a hybrid drive device for a motor vehicle. The hybrid drive device includes at least one first drive unit and one second drive unit. The first drive unit and the second drive unit can be operatively connected mechanically by means of a clutch. To start the first drive unit, the clutch is at least partially closed, and the first drive unit is thus accelerated by means of the second drive unit. During the starting of the first drive unit, the second drive unit is operated with speed regulation.
Claims8
A method for operating a hybrid drive of a motor vehicle, wherein the hybrid drive has at least one first drive unit and one second drive unit, wherein the first drive unit and the second drive unit can be operatively connected mechanically by means of a clutch, the method comprising:
- starting the first drive unit by at least partially closing the clutch and thus accelerating the first drive unit by means of the second drive unit, and
- regulating the speed of the second drive unit during starting of the first drive unit.
A controller for operating a hybrid drive of a motor vehicle, the hybrid drive having at least one first drive unit and one second drive unit,
- wherein the first drive unit and the second drive unit can be operatively connected mechanically by means of a clutch,
- and wherein the controller is configured to
- control the clutch to start the first drive unit and so that the first drive unit is accelerated by the second drive unit,
- regulate the speed of the second drive unit during starting of the first drive unit.
A hybrid drive for a motor vehicle, the hybrid drive comprising:
- at least one first and one second drive unit,
- a clutch, and
- a controller,
- wherein the first drive unit and the second drive unit can be operatively connected mechanically by means of the clutch,
- and wherein the controller is configured to control the clutch to start the first drive unit when the clutch is at least partially closed and the first drive unit is thus accelerated by the second drive unit,
- wherein the at least one controller regulates the speed of the second drive unit during the starting of the first drive unit.
