Abstract:
1. A method for controlling a motor, comprising: dividing a pulse-width-modulated switching signal into a predefined plural number of pulse-width-modulated control signals; defining a functional channel for each pulse-width-modulated control signal such that there is the predefined plural number of functional channels; driving a bridge circuit with the functional channels; controlling and driving the motor with the bridge circuit; generating a mutually independent switch-off signal for each functional channel such that the predefined plural number of switch-off signals is generated; supplying the switch-off signals independently of one another, to a decoupling unit; decoupling the switch-off signals from one another in the decoupling unit; and switching off the functional channels independently of one another on the basis of at least one of the switch-off signals.
