Patent ID: 7693644

Claim:
A regulator device for compensating for dispersions of a plurality of piezo actuated injectors in each case are assigned to cylinders of an internal combustion engine, comprising: a control device configured to provide a cylinder-specific controlled variable and a command variable, of which a primary manipulated variable is a variable that represents an electrical power supplied during an activation cycle to the piezo actuator; and a manipulated variable splitting unit where the input variable is a regulator value of the primary manipulated variable determined by the regulator is embodied for determining a total value of the primary manipulated variable as a function of the regulator value, for splitting the total value into a primary value of the primary manipulated variable and a secondary value of a secondary manipulated variable as a function of a lower and/or upper threshold value of the total value where the manipulated variable splitting unit increases the secondary value beyond the amount needed for implementing the difference between the total value and the primary value if the regulator value exceeds the upper threshold value, and retaining the increase until the regulator value falls below a hysteresis threshold value in relation to the upper threshold value.
