Piezoelectric actuator control method for a vehicle combustion engine fuel injector, whereby a value characterizing the onset of hydraulic triggering is measured and used to determine a correction value for a predefined set value

摘要

Method for controlling a piezoelectric actuator that service to control a fuel injector, in which a value is determined that characterizes the beginning of hydraulic triggering. The value is compared with a predefined set value and based on the comparison a correction value is determined for a regulating value. Independent claims are also included for the following; (1) a device for controlling a piezoelectric actuator; (2) stored software.
