Abstract
A hybrid drive apparatus has a first drive unit, a second drive unit, and a clutch by way of which the first drive unit and the second drive unit can be coupled. A method for controlling the hybrid drive apparatus includes decoupling the first drive unit and the second drive unit from each other, and operating the first drive unit at a no-load operating point. A first torque of the first drive unit is determined at the no-load operating point. The first and second drive units are coupled by way of the clutch. The first drive unit is then motored by the second drive unit at an operating point which corresponds to the no-load operating point. A second torque is determined, which is produced by the second drive unit, in order to motor the first drive unit at the operating point. Finally, a control of at least one of the drive units is adapted based on the difference between the first torque and the second torque.
