As can be seen from Fig. 1, the actuating arrangement comprises for opening and closing swiveling vehicle wings 3 a control unit 1, a fluid drive 2, which, for example a controlled fluid drive 2.1, 2.2 and an uncontrolled Fluid drive 2.3, 2.4 comprises a sensor unit 4, which comprises a rotation angle sensor, a memory 5, which can also be part of the control unit 1, and control elements 6, which, for example, in the vehicle interior, on the trunk lid or are arranged on a portable remote control. The controlled one Fluid drive comprises a hydraulic unit 2.1 and one Hydraulic cylinder 2.2. The uncontrolled fluid drive includes a Gas spring pair 2.3 and 2.4.

2 shows a schematic representation of a control sequence of the trunk lid 6. If you want to open which of the Control unit 1 is transmitted via controls 6 controls Control unit 1 to the controlled fluid drive 2.1, 2.1, so that the boot lid 6 from its starting position A in the direction End position E is moved. This is in the diagram by the arrow Opening direction OR shown. When reaching a first from Vehicle manufacturer predetermined opening angle O1, which in Memory 5 is stored, the control unit switches the hydraulic unit 1 from. For the last movement phase of the opening movement between the first predetermined opening angle Oil to the end position E, the boot lid 6 is only through Gas spring pair 2.3, 2.4 driven. The hydraulic cylinder 2.2 is released in this phase, so that the piston rod through the drive lever 3 is moved further in the opening direction.

In the event of a request for closure, which the control unit 1 likewise is transmitted via the controls 6, switches Control unit 1, the hydraulic unit 2.1 again, the Hydraulic cylinder 2.2 now in the opposite direction is pressurized. To do this, the control unit activates 1 corresponding fluidic switching elements, for example a Multi-way valve. The boot lid 3 is now from its end position E moved in the direction of its starting position A. This is in the diagram represented by the arrow closing direction SR. When reached a second specified by the vehicle manufacturer Opening angle O2, which is also in memory 5 is stored, the control unit 1 switches the hydraulic unit 2.1 again. In the last movement phase of the Closing movement between the second predetermined opening angle O2 and the starting position A only the spring force of the Gas spring pair 2.3, 2.4 against the weight of the boot lid 3. The spring force of the gas spring pair 2.3, 2.4 is so dimensioned that the weight of the boot lid 3 is sufficient, to reach the starting position A. The hydraulic cylinder 2.2 is in this phase as well as the opening movement released so that the rod head through the drive lever 3rd is moved further in the closing direction.

Other opening angles can also be used Opening angle for an intermediate layer, for example by the user, be programmed. Such an opening angle is in the diagram Z is drawn, which is the limitation of the opening angle represents a collision with a removable roof structure, for example, a ski box or a surfboard. Is such an opening angle for an intermediate layer stored in memory 5, then an opening operation of the Rear lid stopped when this opening angle Z is reached. The opening angle is programmed using a Input system in the vehicle interior or through a special one Operating sequence of the control element. So the programming process for example by operating a certain control element for a specified period of time (e.g. 5 seconds) and then opening the boot lid until reaching the desired opening angle and pressing the control element again for a specified period of time to take over the desired opening angle in the memory 5. In addition, desired Opening angle in the workshop via a programming device, which is connected to the vehicle bus in the Memory 5 can be entered.

To detect whether a given opening angle has been reached, the control unit 1 compares the at regular intervals Output signals of the sensor unit 4, which the current opening angle correspond with the saved opening angles. If there is a match, a controlled drive is switched off, or the movement of the vehicle wing stopped.

As can be seen from Fig. 3, the controlled fluid drive comprises a hydraulic unit 2.1, a hydraulic cylinder 2.2 and a drive lever 7 and is in the right side area of the Trunk arranged. The driving force of the hydraulic cylinder 2.2 is on the drive lever 7 and an axis 8 on one Transfer lever of the right multi-joint hinge 9, wherein the drive lever 8 articulated with the rod head of the hydraulic cylinder 2.2 is connected. About the multi-joint hinge 9 is the boot lid 3 around a horizontal vehicle transverse axis pivoted on the body. The discharge of the Trunk lid 3 takes place on both sides of the trunk lid 3 the multi-joint hinges 9 by one uncontrolled Fluid drive 2.3, 2.4. The uncontrolled fluid drives 2.3, 2.4 are designed as gas pressure springs 2.3, 2.4 and under mirror symmetry Arrangement in the right or left water drainage channel arranged. Fig. 3 shows the boot lid in its initial position A (closed).

Fig. 4 shows the trunk lid 3 in its end position E (completely open). The telescopes as uncontrolled fluid drives 2.3 and 2.4 serving gas springs 2.3, 2.4 are complete in the shown extended position in which the gas springs 2.3, 2.4 the maximum possible opening angle E of the boot lid limit and form the stop.

Fig. 5 shows the arrangement of the rotation angle sensor 4 on the hinge bracket 10. The angle of rotation sensor 4 is over a Coupling rod 4.1 connected to the drive lever 7 to the Position to be continuously recorded and sent to the control unit 1 forward. The control unit 1 evaluates this current Opening angle compares this with the saved one predetermined opening angles. The control unit also determines 1 a current change in opening angle and compares it with the normal change in opening angle, which depends on the running time the opening or closing movement is dependent. Will inside of a given time window (e.g. 100 ms) none If the change in the opening angle is recognized, the control unit closes an obstacle in the direction of movement of the boot lid 3 and stops the opening process. Then the Direction of movement of the boot lid 3 reversed and up to Starting position of the interrupted closing or opening movement executed.
