Abstract
In a method for determining the actuator energy required for the different injection types of an actuator of an internal combustion engine, the actuator is impinged by a control signal in such a way that an actuator signal is generated and an injection parameter of the internal combustion engine is set in such a way that said actuator signal is generated at a specific stored time. The first injection type in the combustion cycle is first deactivated in order to determine the actuator energy of said type from the second injection type.
