Abstract
A method of calculating the voltage setpoint of a piezoelectric element as a function of a rail pressure is provided, in which a corrected voltage setpoint is formed by, among other adjustments, using a multiplier as a function of a temperature of the piezoelectric element. Additional adjustments for forming the corrected voltage setpoint includes adjusting the setpoint control voltage by multiplication by at least one correction value (multiplier) and/or by addition of at least one correction value (addend).
Claims4
A method of calculating a voltage setpoint of a piezoelectric element as a function of a rail pressure, comprising:
- adjusting a setpoint control voltage by at least one of multiplication with at least one correction multiplier value and addition of at least one correction addend value;
- and
- adjusting the setpoint control voltage as a function of a temperature of the piezoelectric element by using a further multiplier;
- wherein a corrected voltage setpoint is formed from the adjustments.
