Abstract
In a method for controlling an electric pump drive motor of a power steering device, a high output stage and a low output stage are provided, in which the motor can be operated. Between the two output stages at least one further middle output stage in which the motor can be operated is provided. A switchover between the three output stages takes place as a function of the current consumption of the motor.
