The invention relates to a method for operating an electric machine (1) by means of a triggering system. According to said method, an operational parameter of the electric machine (1) and/or the triggering system is monitored, the plausibility of the input parameters is checked via the check sum and relevance with respect to the current situation, the admissibility of a real moment (Mist2) of the electric machine (1) is verified in accordance with the operating state of the electric machine (1), and an error reaction is induced when the input parameters are not plausible or the real moment (Mist2) is inadmissible. In addition, verification is made as to whether the planned change in the rotational speed can be implemented, and the electric machine (1) is switched into a more favorable mode of operation when said change cannot be implemented. The admissibility of the real moment (Mist1) is preferably verified in such a way that maximum and minimum admissible threshold moments Mmax_z and Mmin_z are formed while Mist2 is compared step by step to a value Mist1, the thresholds Mmax_z and Mmin_z, and a reduced and delayed setpoint moment Msoll_r. The invention can be utilized for monitoring an electric machine (1) used as a starter/generator in a motor vehicle. |
