Abstract
A method for operating a drive motor of a drive system, including the following: providing a control variable, which is ascertained as a function of one or multiple state variable(s) of the drive system and as a function of a default variable, to an output stage for operating the drive motor; reading the control variable previously provided to the output stage back from the output stage to obtain a read-back control variable; ascertaining a back-calculated torque from the read-back control variable; comparing the back-calculated torque and a predefined monitoring torque; and providing the control variable or an alternative control variable ascertained from the monitoring torque to the output stage as a function of a result of the comparison for the purpose of operating the drive motor.
