    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： An electrical machine in a motor vehicle is controlled by an inverter, which motor vehicle has an automatically or manually actuatable transmission. The electrical machine generates, in generator mode, electrical energy that is stored in an energy reservoir. In a fault situation, at least one variable characterizing the charge state of the energy reservoir is detected and compared with a predefined lower threshold value, and upon a shortfall below the lower threshold value, the electrical machine is switched into a freewheeling mode by opening the inverter's switching elements. For an automatic transmission, a higher transmission ratio than a present transmission ratio is additionally established; for a manual transmission, the driver is notified by a message that a lower gear needs to be engaged.
