Abstract

A method for the electric control of an actuator of an injection valve in an injection facility for an internal combustion engine has the following steps: specifying a target value for a controlled variable (E) of the actuator, pilot controlling the controlled variable (E) according to a pilot control characteristic that is specified by an axis section (OffsCal, Offs-Real) and a characteristic gradient, wherein as part of the pilot control corresponding to the specified target value according to the pilot control characteristic a control variable for the electric control of the actuator is determined, and readjustment of the pilot control characteristic, wherein a control deviation (ΔE) is ascertained as part of the readjustment and the pilot control characteristic is adapted as a function of the control deviation (ΔE). It is proposed that as part of the readjustment the axis section of the pilot control characteristic is set.
