Abstract
A method and a device for operating a vehicle having a hybrid drive are described, in which a first drive unit and a second drive unit contribute jointly or individually to the drive of the vehicle, the first drive unit driving the second drive unit in the manner of a generator for charging an energy storage device, the first drive unit and the second drive unit being separable by a drive train element transferring a torque of the first drive unit. In a method in which it is ensured that the vehicle may continue to drive safely even in the event of a defect in a drive train element between the first drive unit and the second drive unit, the torque portion used for charging the energy storage device is reduced to a minimum torque, while the torque excess, which is reduced in the event of a defect in the drive train element but still exceeds the minimum torque, is utilized to propel the vehicle.
