A method for transmitting data among components of the system electronics of mobile systems, where, to increase the security of the information exchange, it is proposed to encrypt the data to be transmitted. To this end, devices for encrypting and/or decrypting data to be transmitted or received are provided in the relevant system electronics components.

A method of producing a number of pressure sensors includes joining a plurality of support bodies to a metal component, the metal component forming a diaphragm, applying a thin-film coating to produce the sensor elements, and finally dividing the metal component provided with the thin-film coating and the support bodies into a plurality of pressure sensors, each having a single one of the support bodies so that the number of pressure sensors formed corresponds to the plurality of the support bodies.

The digital interface unit ( ) for control of a peripheral device, especially for controlling a magnetic valve for an injection device, includes a plurality of output registers ( to ), which store and output a set of control variables applied to the input sides of the respective output registers in response to a control signal ( , MST E). So that the control variables are output from the output registers exactly simultaneously even though they are received sequentially, at least one group of buffer registers ( to to ) is connected to the output registers ( to ). The buffer register or registers provides intermediate storage for the control variables prior to output from the interface unit.

The external intelligent component ( ) connected with a microprocessor system ( ) is described for essentially automatic control of a control element ( ) without burdening the microprocessor system operation. The control parameters for the control element ( ) are written into a data memory ( ) of the external component ( ) from the microprocessor system ( ) and are read out internally from the data memory ( ) during normal operation of the external component ( ). Control of the external component ( ) is possible by the microprocessor system ( ) without blocking the system bus ( ) of the microprocessor system ( ) using a control line from the microprocessor to a reset input (RESET) of a controller ( ) of the external component ( ).

A clock signal loading device for a processor of a controller connected to a network and a clock signal loading method are provided. The device includes a first oscillator for generating a clock signal that can be loaded to the processor, a controllable clock signal changer for changing the clock signal generated by the first oscillator, and a control device connected to the network for generating a control signal for controlling the clock signal changer as a function of the communication signals transmitted over the network. This device and method allows the frequency of the clock signal needed by the processor to be tuned in a simple and flexible manner.

A method and a device for controlling a load, in particular a solenoid valve for controlling the quantity of fuel to be injected. The load receives a bias current value before being activated. This bias current value is adapted.

A method and device for switching an inductor are described. A first terminal of the inductor may be connected to ground via a first switching device. A second terminal of the inductor is always connected to a voltage power supply. A second inductor may be connected to ground via a second switching device. The energy released in the second inductor when the current flow is interrupted is used to switch the first inductor.

A device for controlling a multi-cylinder internal combustion engine with a rotatable shaft has a transmitter wheel mountable on the rotatable shaft and having a number of uniform spaced angular marks spaced and at least one reference mark which as a synchronization mark for forming control pulses for the internal combustion engine, a sensor which senses the transmission wheel and supplies a rectangular output signal corresponding to its surface, a computing device which evaluates the output signal and compares time intervals of uniform signal flanks with one another or sets them relative to one another in a certain ratio, to recognize the reference mark, and after a first recognition of the reference mark occurrence of the reference mark by counting of the uniform signal flanks is recognized and in addition the distance of the signal flanks is tested and thereby the recognized reference mark is tested for plausibility, an error counter arranged so that when a non plausibility is recognized it is incremented by 1 and during computation of the control pulses the reference mark is considered and a next detection of the reference mark is performed with a same process until a counter condition of the error counter reaches a predetermined value, and when the counter condition reaches the predetermined value a synchronization is rejected and a new synchronization is performed.

Adjustable voltage divider produced by hybrid technology

A device for triggering an electromagnetic load. The load is formed by at least two partial inductances. The load can be connected to the ground via a first switching device, and a partial inductance can be connected to the ground via a second switching device. The first switching device is triggered as a function of a voltage measured between the partial inductance and the second switching device.

A method and a device for the closed-loop control of a control element having integral action, particularly an injection-timing device of a high-pressure fuel pump. Using a system deviation as a baseline, a controller preselects a driving signal to be applied to the control element. In the event of an error in the area of actual-value ascertanment, an emergency travel operation is initiated. A signal is applied to the control element, such that at least short-term, it assumes a defined position.

During a third phase, in addition to the control device, a second switching device is driven that is disposed parallel to the control device.

A method and an apparatus for controlling an electromagnetic switching member having an excitation winding and a movable armature. A first time point and a second time point define a time window. Within the time window, the current characteristic and/or the voltage characteristic is evaluated in order to detect a switching time point at which the armature reaches a new limit position. The time window is enlarged if no reliable switching time point was detected within the time window.

In a device and a process for controlling an injection actuator of a self-igniting internal combustion engine, on the basis of the operating conditions, a fuel amount signal (QKO) can be given, which depends at least on the driver's command. Under certain operating conditions, regardless of the driver's command, a minimum amount is injected to actuate the injection actuator.
