Abstract: Processing and transmitting of data within a functionally safe electronic system having at least two subsystems, each of which comprises at least one safety component, and each of which complies with a specific safety level for functionally safe data processing. Embodiments process data using the safety component of a first one of the subsystems into functionally safe data of a first safety level, and add an indication attribute indicating suitability of these data for use of this first safety level; transmitting the data to a second one of the subsystems; and checking the received indication attribute, by the second subsystem using the safety component, to determine whether the safety level indicated by this indication attribute is different from the safety level the second subsystem complies with; and, if the check reveals non-equal safety levels, further processing the data in functionally a safe manner based on the lower safety level.

Abstract: The present invention relates to a joint unit for an articulated connection of at least one first component and one second component. The joint unit comprises a joint body, in particular a sleeve-like joint body, connectable to the first component. A first joint element is arranged rotatably supported about a first axis of rotation in the joint body. The first joint element has at least one bearing section that receives a second joint element that is rotatably supported about a second axis of rotation and that is connectable to the second component.

Abstract: A method for operating a quantity-controlled internal combustion engine having at least two cylinders, including the following steps: ascertaining a present operating state; determining a number of cylinders or cylinder groups to be deactivated in dependence on the present operating state; deactivating or keeping deactivated a fuel supply for at least one cylinder to be deactivated or at least one cylinder group if at least one cylinder or at least one cylinder group is to be deactivated; and opening a flow-influencing element associated with the at least one cylinder or the at least one cylinder group for a fresh mass supply to the at least one cylinder to be deactivated or the at least one cylinder group to be deactivated.

Abstract: A switchover method for a solenoid valve, operated in analogized form, in an electrohydraulic brake system, in which method the solenoid valve can assume a closed position, an open position and a multiplicity of intermediate positions in accordance with electrical actuation or regulation, and wherein the actuation or regulation is performed as a function of a known current-pressure characteristic curve of the solenoid valve. Upon a switchover of the solenoid valve, a pressure-dependent and/or current-dependent magnetic hysteresis characteristic of the solenoid valve is compensated directly without prior modification of the present hysteresis characteristic. An electrohydraulic brake system and the use of the brake system is also disclosed.

Abstract: A control valve conditioning method in an electrohydraulic pressure control unit comprising at least one electrically triggered solenoid valve that is controlled in an analog manner. The solenoid valve is operated at a specific operating current according to a functional correlation or characteristic diagram between the valve current and the differential pressure characteristic curve when the pressure is controlled, said functional correlation or characteristic diagram being stored in the pressure control unit. The method comprises the following steps: a) temporarily applying at least one anti-hysteresis pulse to the solenoid valve during which a current is set far below or far above the operating current in the valve; b) applying the anti-hysteresis pulse at the desired operating current before or during controlled operation, and c) applying the anti-hysteresis pulse wherein the duration is limited in such a way that the anti-hysteresis pulse has largely no influence on the brake pressure.
