Abstract
Injectors each having a piezo actuator are assigned to cylinders of an internal combustion engine. A regulator device is configured for furnishing a cylinder-specific controlled variable and a command variable to a controller whose primary manipulated variable is a variable representing an electrical power supplied to the piezo actuator during a control cycle. A manipulated variable splitting unit is provided whose input variable is a regulator-determined regulator value of the primary manipulated variable and is configured for determining a total value of the primary manipulated variable according to the regulator value. It is also configured for splitting the total value into a primary value of the primary manipulated variable and into a secondary value of a secondary manipulated variable according to a lower and/or upper threshold value of the total value.
