A device and a method are described for controlling an electromagnetic user, especially a magnetic valve for influencing the fuel quantity to be injected into an internal combustion engine. At least one switching time of the user is taken into consideration in the control. The at least one switching time is ascertained starting from a current value.

Method and device for controlling an electromagnetic consumer

An arrangement for monitoring the drive of an actuator includes an output-stage component which includes a counter. With the aid of the counter, the switch-on time of the actuator is determined. The determined switch-on time is made available to the microcomputer for diagnostic purposes.

Method and arrangement for monitoring the drive of an actuator

Method for operating an internal combustion engine in which fuel is injected into a combustion chamber by an injector. The injector has a drivable piezo-actuator. A setpoint value is generated for driving the piezo-actuator. A setpoint charge quantity (QC) is determined from the setpoint value, and an actual charge quantity (QC) supplied to the piezo-actuator is determined. The setpoint charge quantity (QC) and the actual charge quantity (QC) are combined, and the combined result (S) acts upon the drive circuit of the piezo-actuator.

Method, computer program, memory medium and control and/or regulating unit for operating an internal combustion engine, as well as internal combustion engine, in particular for a motor vehicle
