    摘要: In a method for operating an at least three-phase electric machine used as a drive assembly in a motor vehicle, which is actuated via an inverter, the inverter including switching elements in the form of half bridges which are in each case electrically connected to a respective phase of the electric machine, when a first switching element of a first half bridge connected to a first phase is permanently closed/opened on account of failure, a second switching element of the first half bridge is permanently opened/closed and, in a first angular range of an electrical rotation, which is uninfluenced by the first phase, all switching elements of the additional half bridges are actuated in the usual manner.

    摘要: 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.
