• a first sensor assigned to a drive element is provided, which can distinguish at least between a setting-up process and a manual opening process of the motor vehicle door. This is intended to provide a low weight at the same time as improved comfort.
• a force measuring device is accommodated in a setup device in such a way that a movement of a transmission carrier can be detected.
• the gear carrier represents a component of a gear, which belongs to the electric motor drive and is arranged between the mounting element and the electric motor drive.

• a locking means and in particular a locking lever is additionally provided.
• the locking means or the locking lever can be controlled electronically, in particular with the help of the electric motor drive.
• the sensor can be used to detect a force acting on the installation device.
• the procedure is such that the pulling force of an operator is detected with the help of the sensor, thereby initiating unlocking of the locking means or locking lever.
• the primary purpose of the locking means or locking lever is to be able to realize the possibility of a closing movement using the setting device.
• the setting-up device can work as a combined setting-up and closing device.
• the sensor ultimately takes on a security function in such a way that the locking can be stopped, prevented or canceled if excessive forces occur. This prevents any damage to the installation device.
• the state of the art has proven itself in principle, but still offers room for improvement.
• the general problem with such installation devices is that forces acting on them or on the motor vehicle door from outside are not controlled or can only be controlled to a very limited extent. These external forces can be, for example, wind acting on the motor vehicle door.
• the invention is based on the technical problem of further developing such an installation device in such a way that, in particular, independent opening processes of the motor vehicle door following an installation process can be controlled.
• the invention proposes in a generic setup device that the traversing element can be acted upon or is acted upon, at least independently of the operator, in accordance with signals from the sensor.
• the traversing element is initially acted upon independently of an operator or the intervention of an operator. This means that the movement element is acted upon predominantly and at least independently of the operator.
• the traversing element is acted upon depending on signals from the sensor. If, for example, the sensor assigned to the installation element registers a low or even decreasing force during the installation process using the electric motor drive, this indicates that the motor vehicle door moved with the aid of the installation device is also subjected to external forces. These external forces can be, for example, a gust of wind or gravitational forces that act on the motor vehicle door, for example when parking on a slope.
• the invention In order to be able to determine such an external force that additionally acts on the motor vehicle door or an associated motor vehicle wing, the invention generally proceeds in such a way that, for example, in a control unit that is already provided for acting on the electric motor drive as well as for reading out the sensor time-dependent force curve for acting on the installation element is stored as a target force.
• This time-dependent force curve can be an averaged force curve, which has previously been recorded or determined, for example, by operating the setup device several times in a motor vehicle located on one level and then the respective curve of the force detected using the sensor over time recorded and then averaged.
• This target force is checked for deviations with the actual measured force. If the actual force is below the target force, this indicates additional forces acting on the motor vehicle door (and acting in the opening direction).
• the procedure can also be such that the actual force acting on the installation element and determined using the sensor is simply measured (independent of time) and compared with the target force stored in the control unit.
• This target force represents a maximum force that occurs when the installation element is acted upon when the motor vehicle is in one plane. As soon as this target force of the measured actual force is undershot, this indicates that additional external forces are acting on the motor vehicle door or its motor vehicle wing, for example in the form of wind or as a result of gravity.
• the target force which has been stored in the control unit and is compared with the actual force actually acting on the sensor, can also simply be designed as an average force acting on the installation element (and not as a maximum force as before), which is observed when the motor vehicle is on the plane and no additional force acts on the motor vehicle door due to, for example, wind.
• a corresponding target force curve can be determined over time and saved in the control unit.
• the target force or the target force curve over time is compared with the actual force actually acting on the erection element or the actual force curve over time. As soon as the comparison shows at this point that the actual force or the actual force curve over time indicates that an additional external force is acting on the door leaf of the motor vehicle door, the control unit ensures that the traversing element is acted upon.
• the action on the traversing element as a result of an external force acting on the motor vehicle door corresponds to the traversing element holding the positioning element or the motor vehicle door in place.
• the invention ensures that following an erection process using the erection device according to the invention, the erected motor vehicle door cannot swing open in an uncontrolled manner. This prevents any damage to the motor vehicle door as well as, for example, accident situations in such a way that the motor vehicle door in question swings open onto, for example, a cycle path and a cyclist could collide with the motor vehicle door in question.
• the moving element can engage a locking bolt or striker, which is generally located on the associated motor vehicle door.
• a locking bolt or striker which is generally located on the associated motor vehicle door.
• the moving element it is also possible for the moving element to engage behind another hook or a recess in the motor vehicle door and in this way ensure that the motor vehicle door cannot swing open in an uncontrolled manner.
• the control unit Since the previously mentioned target force or the target force curve over time is stored in the control unit, there is also the possibility of not only preventing the motor vehicle door from opening automatically when an external force attacks the motor vehicle door and in this way ensures that the actual force acting on the motor vehicle door or the actual force curve over time is ultimately "below” the target force or the target force curve over time. But there is the additional possibility that when held With the help of the sensor assigned to the positioning element, an additional external force acting on the moving element is determined, which can be traced back, for example, to an operator who wants to open the motor vehicle door. This additional force can now be used so that, depending on this, the control unit controls the moving element deactivates or ensures that the travel element releases the installation element and/or the motor vehicle door.
• control unit acts on the deactivated traversing element depending on signals from the sensor and when an additional external force occurs to hold the installation element or the motor vehicle door in place.
• the loading corresponds to the deactivated one Moving element ensures that the installation element or the motor vehicle door are held in place.
• the design is such that the control unit acts on the activated traversing element depending on signals from the sensor and again when an additional external force occurs to release the installation element or motor vehicle door. In this case, the installation process itself is completed and the traversing element is activated.
• the traversing element is used by an operator to lock the motor vehicle door. It is also conceivable in this context that the activated traversing element is or can be released in the sense of an emergency unlocking.
• the senor can be assigned to the electric motor drive. It has proven to be particularly advantageous if the sensor is integrated into the electric motor drive. Such an integration can advantageously be implemented in such a way that the electrical current consumed by the electric motor as part of the electric motor drive is measured using the sensor. For this purpose, a separate and additional sensor is strictly not required, but rather the course of the electrical current drawn by the electric motor can be recorded over time.

In this case, the moving element actually ensures that the positioning element or the motor vehicle door is held in place.
