A method for operating a hybrid drive of a vehicle, having an internal combustion engine and having at least one electric drive, to which at least one traction battery is assigned, as well as to a hybrid drive, especially a parallel hybrid drive. The internal combustion engine is able to be started

대표청구항 ▼

1. A method for operating a hybrid drive of a vehicle having an internal combustion engine and at least one electric drive to which at least one traction battery is assigned, the method comprising: starting the internal combustion engine from a purely electrical driving operating mode of the hybrid drive using a direct start without a starter;wherein the internal combustion engine of the hybrid drive is started as a function of a torque command of a driver, if the at least one electric drive is not able to implement a desired torque;wherein in response to a non-presence of direct start readiness of the internal combustion engine, a slip torque-regulated separating clutch transmits an engine drag-torque to the internal combustion engine; andwherein after an expiration of a time span within which the internal combustion engine is not started, the separating clutch is opened and the internal combustion engine stops oscillating within a settling oscillating range, the settling oscillating range being within a target shut-off range. 2. The method as recited in claim 1, wherein the starting is performed without assistance from sources that are configured to start the internal combustion engine by cranking from outside the internal combustion engine. 3. The method as recited in claim 1, wherein in response to a presence of direct start readiness of the internal combustion engine, the internal combustion engine is started in response to opened separating clutch. 4. The method as recited in claim 1, wherein in response to an increasing torque command by the driver, the internal combustion engine is started by a dynamic direct start using a start command to a controller. 5. The method as recited in claim 1, wherein the target shut-off range of the internal combustion engine is defined by a setting of at least one cylinder between 100° and 120° past top dead center. 6. The method as recited in claim 1, wherein the hybrid drive is monitored by a controller which has subordinate to it a controller for the internal combustion engine, a controller for the at least one electric drive and a controller for a separating clutch, and the controller implements the torque command of the driver using the at least one electric drive. 7. A parallel hybrid drive of a vehicle, comprising: an internal combustion engine;at least one electric drive; andat least one traction battery assigned to the at least one electric drive;wherein a direct start of the internal combustion engine from a purely electrical driving operating mode of the hybrid drive is performed without using a starter;wherein the internal combustion engine of the hybrid drive is started as a function of a torque command of a driver, if the at least one electric drive is not able to implement a desired torque;wherein in response to a non-presence of direct start readiness of the internal combustion engine, a slip torque-regulated separating clutch transmits an engine drag-torque to the internal combustion engine; andwherein after an expiration of a time span within which the internal combustion engine is not started, the separating clutch is opened and the internal combustion engine stops oscillating within a settling oscillating range, the settling oscillating range being within a target shut-off range. 8. The drive of claim 7wherein the direct start is performed without assistance from sources that are configured to start the internal combustion engine by cranking from outside the internal combustion engine. 9. The drive of claim 7, wherein in response to a presence of direct start readiness of the internal combustion engine, the internal combustion engine is started in response to opened separating clutch. 10. The drive of claim 7, wherein in response to an increasing torque command by the driver, the internal combustion engine is started by a dynamic direct start using a start command to a controller. 11. The drive of claim 7, wherein the target shut-off range of the internal combustion engine is defined by a setting of at least one cylinder between 100° and 120° past top dead center. 12. The drive of claim 7, wherein the hybrid drive is monitored by a controller which has subordinate to it a controller for the internal combustion engine, a controller for the at least one electric drive and a controller for a separating clutch, and the controller implements the torque command of the driver using the at least one electric drive.
