Method of calculating a target voltage for a piezoelectric element

A multiplier (30) uses a temperature (16) for a piezoelectric element (10) to adjust a voltage set-point (14). An adjusted voltage set-point (28) to be calculated is formed from a voltage set-point (14) through multiplication with an adjustment value/multiplier (24) and/or through addition with an a...

More Information
Summary:A multiplier (30) uses a temperature (16) for a piezoelectric element (10) to adjust a voltage set-point (14). An adjusted voltage set-point (28) to be calculated is formed from a voltage set-point (14) through multiplication with an adjustment value/multiplier (24) and/or through addition with an adjustment value/summand. The multiplier/summand are formed from specific data for the piezoelectric element and for tolerances in an injector.
