Abstract
An arrangement () for specifying the pressure (), produced by a pump () driven by an electric motor (), includes a processor () which derives a target pressure value () from an internal torque value () and a loss torque (). The arrangement () further derives () the internal torque value () from a motor current value () and a motor constant k.
