Abstract: An electromagnetic actuating device (10) has an energizable stationary spool element (1) having a stationary core area (2), an anchor unit (3) moveable relative to the spool elements (1) and the core area (2) and has permanent magnet elements (4) and a pestle (5) disposed on one end and having a free end section (5a) for engaging in an actuating partner, the anchor unit (3) being moveable along a longitudinal movement axis (L) in at least two actuating positions (A,B), and the actuator (10) having retaining elements (7) which are spaced apart from the core area, are permanent-magnetically flux-conductive and are formed in such a manner in a third actuating position (C) between the first and second actuating positions (A,B) for interacting with the permanent magnet elements (4) of the anchor unit (3) that the anchor unit is retained in a third actuating position (C) between the first and second actuating positions (A,B) and/or exerts a predefined force potential towards the actuating partner.

Abstract: An aerodynamically effective device for a motor vehicle has an air guide element that can be moved between a position of rest and at least one operating position, a drive unit for moving the air guide element, and a control unit. The control unit is adapted to instruct the drive unit to move the air guide element from the position of rest into the operating position, on reaching a first vehicle speed threshold value. Furthermore, the control unit is adapted to carry out a function test of the drive unit below the first vehicle speed threshold value.

Abstract: A hinge for pivoting a flap, and in particular, to a hinge for pivoting a flap on a motor vehicle. The hinge aids the closing of the flap and includes two linkages or legs which are arranged rotatably around at least one axis of rotation and are connected with one another. A transmission is arranged for transmitting a torque formed during a closing movement of the hinge to a flywheel mass for the accumulation and subsequent aiding and continuation of the closing movement.

Abstract: A system is provided in order to automatically close a filler inlet compartment lid of a car when the lid is in an unintended open position. When predefined signals which are considered to indicate the termination of a refueling operation occur, the system activates a filler inlet compartment lid closing mechanism so that the filler inlet compartment lid is automatically closed and locked. This can take place when the filler inlet compartment lid is completely open or when the lid is in an only slightly lifted intermediate position. The filler inlet compartment lid may reach such a slightly lifted intermediate position, for example, in a drive-through car wash when triggered by the pressure of the car wash brushes.

Abstract: A wheel suspension system for steerable rear wheels of a motor vehicle, having a double-wishbone construction. An upper wheel suspension element and a lower wheel suspension element comprise an A-frame arm arrangement and an opened-up A-frame arm arrangement. A rod link is assigned either to the upper or lower suspension link, and one of the control arms or the rod link is connected with at least one control cylinder for the steering of the rear wheels.

Abstract: A four-wheel steering arrangement for motor vehicles is provided with a first steering device for the front wheels operated by a steering wheel and a second steering device for the rear wheels, which are held by wheel suspension links. The rear wheels are controlled by a hydraulic adjusting device and are adjusted at a variable wheel steering angle ratio with respect to the front wheels, as a function of determined driving condition quantities which are fed to an electronic control unit, particularly a vehicle computer. The steering device comprises a hydraulic control cylinder having a restoring device. This restoring device is connected by adjusting elements providing for the adjustment of the rear wheel steering angles so that they can be swivelled around an axis of rotation formed by support joints between the wheel carrier and the wheel suspension link for steering and are slowly returned to a non-steering position upon system failure.
