Abstract
A method for operating an electric machine with a driver system is provided, in which an operating variable of the electric machine and/or of the driver system is monitored. The validity of the input variables is checked with regard to their checksum and whether the input variables are up-to-date, and the permissibility of an actual moment (Mist2) of the electric machine depending on the operating state of the electric machine is checked. In case of invalid input variables or invalidity of the actual moment (Mist2), a fault reaction is initiated. In addition, the implementability of the planned change of rotary speed is checked and, in case of non-implementability, changed over into a more favorable mode of operation of the electric machine. An electric machine used as a starter/generator in a motor vehicle can be monitored.

21. A method for operating an electric machine with a driver system, in which an operating variable of the electric machine or of the driver system is monitored, comprising:
-
checking the validity of input variables of the driver system in two independent function blocks, in parallel; and producing a fault reaction, if at least one of the two function blocks determines that at least one of the input variables is invalid. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
