A method for transferring data from an actuating element to a control unit activating the actuating element. The control unit activates an inductance contained in the actuating element, for the transfer of the data in the actuating element in parallel to the inductance, a load being connected in parallel, or not.

A device and a method for switching over a semiconductor switch with a switching signal acting on a control connection of the semiconductor switch, the switching signal being switched over as a response to registering a switchover of an activation signal; a down time being ascertained between the start of the switchover of the switching signal and the switchover of the semiconductor switch; the switchover of the semiconductor switch being delayed by a waiting period, for example by delaying the output of the switching signal and/or changing the signal level, so that an actual switching time, corresponding to a setpoint switching time, between the registration of the switchover of the activation signal and the switchover of the semiconductor switch is obtained.

Method for switching over a semiconductor switch

A method for operating a valve actuated by way of an actuator, in particular a fuel injection valve of an internal combustion engine of a motor vehicle, in which a first delay time is identified, which time characterizes a time difference between a point in time of a first change in an energization signal for the actuator and a point in time of a first change in the operating state of the valve corresponding to the first change in the energization signal. According to the present invention, from the first delay time at least one second delay time of the valve is inferred, which latter time characterizes a time difference between a point in time of a second change, different from the first change, in the energization signal and a point in time of a second change in the operating state of the valve corresponding to the second change in the energization signal.

Method and control tool for operating a valve

A method for operating a valve, in particular a fuel injector of an internal combustion engine of a motor vehicle, in which an auxiliary variable is obtained as a function of at least one electrical operating variable of an electromagnetic actuator driving a component of the valve, in particular a valve needle, and in which the auxiliary variable is checked for the presence of a predefinable characteristic. A reference variable is ascertained as a function of the auxiliary variable, the auxiliary variable is modified as a function of the reference variable to obtain a modified auxiliary variable, and the modified auxiliary variable is checked for the presence of the predefinable characteristic.

Method and control unit for operating a valve

In a method for operating a fuel injector, a transition range of the characteristics curve of the injector is detected individually and adapted continuously, so that a monotonous characteristics curve is formed, with whose aid high metering precision of the injector is achieved.

Method for operating a fuel injector of an internal combustion engine, and control device for an internal combustion engine

A method for operating a valve, in particular a fuel injector of an internal combustion engine of a motor vehicle, in which an auxiliary variable is obtained as a function of at least one electrical operating variable of an electromagnetic actuator driving a component of the valve, in particular a valve needle, and in which the auxiliary variable is checked for the presence of a predefinable characteristic. A reference variable which characterizes the operating behavior of the electromagnetic actuator is ascertained, the auxiliary variable is modified as a function of the reference variable to obtain a modified auxiliary variable, and the modified auxiliary variable is checked for the presence of the predefinable characteristic.
