    摘要: A device and a method for actuating an injector in a fuel-injection system of an internal combustion engine are described. Using a first calibration method and based on a control parameter, an injector parameter which characterizes the injection process is determined. Starting from this injector parameter, a first feature is determined for calibrating the injector. A second calibration method determines a second feature for calibrating the injector, based on an engine parameter. The first calibration method is monitored on the basis of the second feature.

    摘要: A method for operating an internal combustion engine is described. A base controlled variable for influencing an actual value of an operating variable of the internal combustion engine is ascertained. The actual value of the operating variable is compared to a setpoint value of the operating variable. A correcting variable is ascertained as a function of the comparison. A controlled variable is ascertained as a function of the base controlled variable and as a function of the correcting variable. An actual value of a state variable of the internal combustion engine is ascertained. A start point in time of a time interval of a critical state change of the internal combustion engine is ascertained as a function of the ascertained actual value of the state variable. The controlled variable is essentially ascertained from an intermediate controlled variable and a correcting variable following the start point in time.
