Abstract: In a method for operating a longitudinally guiding driver assist system of a motor vehicle, wherein a comfort curve speed is determined as a function of curve data, wherein the curve data are commensurate with at least one curve to be driven through next by the motor vehicle, wherein a target speed is determined as a function of the curve comfort speed at a defined point of the curve, and wherein the speed of the motor vehicle is adjusted as a function of at least the target speed of the motor vehicle.

Abstract: An operator control element with magnetic return for a number of switching and/or control functions: includes an abutment part; an actuating part which can be moved, for example displaced and/or pivoted, by hand from an inoperative position in at least two opposite directions with respect to the abutment part; magnetic return means for returning the actuating part into the inoperative position; and detection means for producing an electrical signal corresponding in each case at least to the maximum positions and the inoperative position of the actuating part the magnetic return means include at least one actuating part-side ring magnets and one abutment part-side ring magnet arranged in the inoperative position such that the end faces thereof face one another and are spaced apart. They are arranged so as to pull the actuating part towards the abutment part and that they are concentric.

Abstract: Method for operating a longitudinal driver assistance system (2) of a motor vehicle (1), which controls, in a pure follow mode, the speed of the motor vehicle (1) such that a distance to a vehicle in front as the control object remains constant, and which, in a free travel mode, controls the speed to a desired speed, a likelihood of the vehicle (14) in front of pulling out being determined depending on sensor data of at least one ambient sensor. The control with respect to the vehicle (14) in front and/or the control in the free travel mode is modified or ended directly after termination of the follow mode depending on the pulling-out likelihood.

Abstract: A method for operating a longitudinally guiding driver assistance system of a motor vehicle, especially of an ACC system, which is designed to control the speed of a motor vehicle to a desired speed in a free travel mode and/or keeps a controlled distance to a vehicle in front as the control object in a follow mode, at least one control parameter influencing control being adapted depending on at least one item of traffic information that describes traffic conditions on the currently traveled route, especially in the further course of the route, information is received from an external transmitter.

Abstract: The invention relates to a rotary control element comprising a control element body and a rotary button (1) mounted so as to be rotatable about at least one axis of rotation (9), wherein the control element body and the rotary button (1) cooperate such that a first associated switching function is provided by rotating the rotary button (1). The rotary control element according to the invention is characterized by the rotary button (1) being mounted so as to be displaceable relative to the control element body in at least one direction which is substantially perpendicular relative to the axis of rotation (9), with at least one additional switching function being provided.

Abstract: A method for testing the operability of a driver assistance system installed in a test vehicle and operating based on information supplied by sensors which detect a target vehicle traveling in the environment of the test vehicle, in particular a driver assistance system intervening in the longitudinal or transverse guidance of the motor vehicle, includes outputting control signals via a wireless communication link to at least partially control from the test vehicle the operation of the target vehicle for intentionally performing at least one defined driving maneuver.

Abstract: The haptic feedback of a tilt is resource-intensive to produce for conventional operating elements. Consequently, the invention provides an operating element whose tilt haptics are easy and economical to produce. This is achieved by the means that a ball can be moved against an elastic element in the direction of the longitudinal axis of the lever, and in that the ball can also be supported in a detent arranged in a housing in order to produce the haptic feedback.

Abstract: A system is provided that operates on the magnetorheological principle as a detent or wiper element and/or for electrical detection of direction of rotation. The system includes a gear pump, a rotary knob, and at least one gear. The gears is mechanically driven by the rotation of the rotary knob. A magnetorheological fluid is moved and/or pumped within a channel or ring. The viscosity of the fluid is changed by a pulsed magnetic field at a first coil that is provided on the channel, and thereby a change in the torque or the detent is produced. A second coil that is provided on the channel senses a direction of rotation of the rotary knob.

Abstract: A rotary knob device (1, 20) having a key function includes a key (5, 30) in a rotary knob (2, 23), which is operated separately from the rotary knob so that the key (5, 30) need not also be moved when the rotary knob (2, 23) is moved. In this regard, a holder (6, 24.1) is provided inside the rotary knob (2, 23), on which the rotary knob (2, 23) and the key (5, 30) are mounted to be thereby linked together structurally while functioning separately. The rotational control is transmitted by the rotary knob (2, 23), while key, linear movement, control is transmitted through the separate key (5, 30).

Abstract: A rotary switch or controller is structured to have a so-called impact criteria or characteristic by having members with predetermined yield, or breaking, points (5, 6) which are integrated into the rotary switch (1) so that when a high force acts on the rotary switch (1), a top part (2) of a rotary switch or rotary controller (1) is allowed to be collapsed into a front panel (4) of a passenger vehicle or commercial vehicle on which the rotary switch is used. These yield elements (5, 6) may be structured as ribs (6) that have intended breaking points (6.1) therebetween, or may be structured as spring elements (5).
