Abstract: A driving system for at least automated longitudinal guidance for a motor vehicle is designed to determine or receive a virtual acceleration for the motor vehicle, to determine, for each of at least two further road users in the environment of the motor vehicle, the duration until a virtual collision of the motor vehicle with the road user in question, in each case at least in dependence on the virtual acceleration of the motor vehicle, to select one of the at least two further road users as a target object in dependence on the respective durations until a virtual collision of the motor vehicle with the respective road users, which durations were determined for the at least two further road users, and to determine the longitudinal guidance for the motor vehicle in dependence on the road user selected as the control object.

Abstract: A driver assistance system is configured to determine or receive a setpoint value for a control variable of the motor vehicle, to determine or receive an actual value for the control variable of the motor vehicle, to determine a correction value for reducing a deviation between the setpoint value for the control variable and the actual value for the control variable depending on the deviation between the setpoint value for the control variable and the actual value for the control variable, to compare the correction value with a first threshold value, and at least to limit a future change in the setpoint value for the control variable which increases the deviation between the target value for the control variable and the actual value for the control variable depending on the comparison of the correction value with the first threshold value.

Abstract: A control unit for a vehicle is configured to determine, during an approaching manoeuvre of a distance controller and/or cruise controller of the vehicle towards a vehicle in front, whether or not the vehicle will overtake or can overtake the vehicle in front during the approaching manoeuvre. Furthermore, during the approaching manoeuvre, the control unit is configured to adjust a behaviour of the cruise controller and/or adaptive cruise controller of the vehicle on the basis of the above determination.

Abstract: A method is provided for resuming the movement of a motor vehicle after unforeseen stopping in an automated parking process performed by a parking assistance system having automated longitudinal and transverse guidance. If the vehicle is stopped, a decision is made about a resumption of movement of the vehicle in the prior direction of travel that existed before the vehicle was stopped. The decision is made in dependence on the remaining travel path from the current position to the next planned stopping point of the trajectory lying in the prior direction of travel. A stopping point of the trajectory can be a reversal point or the final parking position, for example. If the decision is positive, the movement of the vehicle is resumed in the prior direction of travel. If the decision is negative, the movement of the vehicle is resumed against the prior direction of travel. Alternatively, in the case of a negative decision, the movement of the vehicle may not be resumed and the parking process may be ended.

Abstract: A relative pressure measuring instrument has a reference pressure feed that offers a high measure of safety and is easy to produce.

Abstract: A pressure sensor element for mounting in a connecting element comprises an isolator body with a laterally projecting membrane. The laterally projecting membrane covering an opening of a passage through which the pressure present at the surface of the membrane is conveyed to a pressure transducer element by means of a hydraulic fluid. In order to mount the pressure sensor element, it is secured in a mounting aperture of the connecting element. The projecting perimeter of the membrane is secured to the surface surrounding the mounting aperture of the connecting element by means of a continuous seam. A membrane type ring in combination with a conventional membrane may be substituted for the projecting membrane, wherein the membrane type ring covers the gap between the pressure sensor element and the adapter element.

Abstract: The aim is to specify a relative pressure measuring instrument having a reference pressure feed that offers a high measure of safety and is easy to produce, having a relative pressure measuring cell (1) having a pressure sensitive element (3), on whose process-facing side there is present during operation a pressure (p) to be measured, on whose process-averted side there is present during operation a reference pressure (pR) to which the pressure (p) to be measured is to be referred, a support (5) on which the relative pressure measuring cell (1) is arranged and which is enclosed in a housing (9), a process connection (15), that is connected to a process-facing end of the housing (9), a measuring instrument housing (17) that is arranged at a process-averted end of the housing (9), and a reference pressure feed through which during operation the reference pressure (pR) is led to the process-averted side of the pressure sensitive element (3), and which leads completely out of the relative pressure measuring inst

Abstract: A pressure sensor element for mounting in an adapter element (40) comprises an isolator body (10) with a laterally protecting membrane (20). The membrane (20) covers an opening of a passage (12) through which the pressure present at the surface of the membrane (20) is conveyed to a pressure transducer element (30) by means of a hydraulic fluid (32). In order to mount the pressure sensor element, it is secured in a mounting aperture of the adapter element (40). The projecting perimeter of the membrane (20) is secured to the surface surrounding the mounting aperture of the adapter element (40) by means of a continous seam. A membrane type ring in combination with a conventional membrane may be substituted for the projecting membrane, wherein the membrane type ring covers the gap between the pressure sensor element and the adapter element.

Abstract: The electrodes of these pressure or differential pressure sensors are formed using a technique other than silk-screen printing or sputtering: The pressure sensor (10) has a substrate (1) and a first major surface (11), a second major surface (12) and a circumferential surface (13. A plate-shaped electrode (14) of electrically conductive material is secured in a recess (15) in the major surface (11) in a high-pressure-resistant and high-vacuum-tight manner by a joining material (16). A through connection (17) is provided from the electrode (14) through the substrate (1) to the major surface (12) or the circumferential surface (13). A diaphragm (2) of ceramic, glass, or single-crystal material is attached to the substrate (1) outside the recess (15) along a joint (18) by a joining material (26), and forms itself a further electrode or is covered, on a surface facing the electrode (14), with a further electrode (24) which is contacted through the joint (18).
