Abstract
A method for controlling an electrical machine of a hybrid drive includes: ascertaining at least one operating parameter value of the electrical machine; identifying an error, if the at least one operating parameter value does not correspond to the standard state of an operating parameter; and at least partially restricting the operation of the electrical machine as a propulsion unit if an identified error exists. The electrical machine is operated at least temporarily as a starter when an identified error exists, independently of the operation of the electrical machine as a propulsion unit.
