A method for changing from electrical operation to hybrid operation in a vehicle hybrid drive is provided. The method includes detecting an increase in a target traction power and starting the internal combustion engine. When the internal combustion engine starts, the method includes outputting a positive torque by generating an increasing generator power. The generator power is used together with an electrical power of a storage unit for generating electrical traction power. The generator power is generated while the internal combustion engine is not yet fully coupled to an output. The method includes fully coupling the internal combustion engine to the output after the generation of the increasing generator power has begun. After the internal combustion engine has been fully coupled, the method includes reducing the electrical power of the storage unit to a non-positive value and adjusting the generator power in accordance with a predetermined energy balance.
