Abstract
A method operates a hybrid drive of a motor vehicle, which hybrid drive has an internal combustion engine and a first electric machine. The method generates, in response to a predefined setpoint torque value, a composite torque which drives the motor vehicle. In a transient operating mode which occurs during a change of the predefined setpoint torque value by a value, the composite torque is generated by summing a drive torque which is generated by the internal combustion engine and a drive torque which is generated by the first electric machine. At least one second electric machine is provided which is switched on during the transient operating mode in order to generate the composite torque of the internal combustion engine and of the first electric machine.
