Methods for opening and / or closing a door or flap of a motor vehicle are known from the prior art, in which an outside door handle designed as a handle is arranged flush in a motor vehicle door, the outside door handle having an actuating element. Upon actuation of the actuating element, the door outer handle is arranged by a drive device from its rest position, in which it is flush in the motor vehicle door, in a use position in which the outside door handle at least partially spaced from the body of the motor vehicle, in particular from the motor vehicle door, transferred. When extending the outside door handle from the rest position to the use position a door lock of the vehicle door is unlocked by the drive device at the same time. The inside door handle is decoupled from the drive device described above. Therefore, the door inner handle is assigned its own drive device.

From the DE 42 17 139 A1 is a handle assembly for pivoting a folding body part, in particular a luggage compartment lid of a passenger car known. The handle assembly has a first and a second handle part, which are pivotally mounted on the body part and can be displaced via an actuating element from a contour of the body part approximately flush rest position in a projecting over the contour and lockable position.

From the DE 10 2007 039 804 A1 a tailgate handle system has become known, which in a first embodiment in the lower region of the tailgate has two recesses, in each of which a handle is arranged and which are each closed by a cover flap. The handles are rotatably mounted about a second axis and are rotatable in their operating position in a rotational direction. The cover flaps are rotatably mounted about a third axis.

From the DE 10 2013 109 930 A1 has become known a drive arrangement for the motorized adjustment of a cover flap arrangement for a handle arrangement of a motor vehicle door. The cover flap assembly has two cover flaps. The drive arrangement has a drive motor and a drive train connected downstream of the drive motor with a feed gear for generating drive movements for the cover flaps.

The object of the invention is therefore to provide a method which is inexpensive and comfortable for a user feasible.

The object is achieved by a method for opening and / or closing a door or flap of a motor vehicle having at least one handle provided with a first actuating element, in particular an outside door handle, and a second handle provided with a second actuating element, in particular a door inner handle, wherein the first Handle and the second handle in each case by a common drive device between a Resting position and a use position is designed to be movable, a door lock, which is also connected to the drive device, in particular mechanically, and a control device for driving the drive device, wherein the control device is electrically connected to both the first handle and the second handle, wherein the drive device is coupled to the first handle and to the second handle and to the door lock, so that upon actuation of the first or second actuator by the drive device at least one handle is transferred to the use position and / or the rest position and the door lock unlocked and / or locked. The inventive method is now advantageously dispensed with a separate drive device for the inside door handle. Furthermore, the comfort for the user is improved by providing the door inner handle with an actuator. To leave the interior of the motor vehicle, the user only has to actuate the actuating element in order to unlock or lock the door lock, which may be designed as an electric door lock.

According to a preferred embodiment of the method can be provided that when operating the first actuating element or the second actuating element both the first handle and the second handle is transferred by the drive device in its position of use and the door lock is unlocked. This offers the advantage that a user who is located outside the motor vehicle can also open the door when required, thereby further improving the comfort for the user in the interior of the motor vehicle. It is also advantageous if the user would like to effect from the outside that a person within the motor vehicle has a comfortable access to the inside door handle.

According to an alternative embodiment of the method can be provided that upon actuation of the first actuator only the first handle is transferred by the drive device in its position of use and unlocks the door lock by the drive device, or that upon actuation of the second actuator only the second handle by the drive device is transferred to its position of use and the door lock is unlocked by the drive device. As a result, only the handle is moved in an advantageous manner, which was selected by the user by actuating the actuating element. As a result, the other handle remains in its rest position, so that the life of the handle is automatically extended due to a shorter service life.

According to a further preferred embodiment of the method it can be provided that the first and / or the second actuating element comprises a capacitive sensor and / or an optical sensor and / or a magnetic sensor which is switched during movement and / or approach of a body part and then forwards an electrical signal to the controller. Capacitive sensors, magnetic sensors and also optical sensors are due to their Small size very well suited to accommodate this in a handle. In this case, the optical sensor and / or the magnetic sensor and / or the capacitive sensor can both be arranged in the first and / or second handle, in particular in the inside door handle and / or in the outside door handle. These can then also work redundantly, so that if one sensor fails, the other sensor is activated.

According to a further preferred embodiment of the method can be provided that the first handle is flush in a body, in particular in a door or flap of the motor vehicle, is arranged. In the case of the outside door handle, the aerodynamic properties of the motor vehicle can be improved if the outside door handle remains in its rest position while driving. Thus, it can further be provided that from a predetermined speed of the motor vehicle, the outside door handle and / or the inside door handle is transferred from the use position to the rest position by the drive device. Therefore, the method can also be carried out very comfortably for the user if the second handle is arranged flush in a panel of the door or flap of the motor vehicle.

According to a further preferred embodiment of the method can be provided that the drive device is designed as an electric motor. The electric motor is a low-cost component that can be easily and safely connected to the control device.

The comfort of the method can be further improved for the user if, after a predetermined time t, the first handle and / or the second handle is automatically returned from the position of use back to the rest position. Thus, it is excluded that the user must operate the first and / or second actuator again.

The invention will be described in more detail with reference to an embodiment. The single FIGURE shows a block diagram with which the method according to the invention can be carried out.

In the single figure, a simplified block diagram is shown, with which the inventive method is described in more detail. As can be seen well in the figure, an outside door handle 1 (TAG) and a door inside handle 2 (TIG) are electrically connected to a controller 3 (ECU). The control device 3 is in turn provided with a drive device 4 (AV) designed as an electric motor. electrically connected. The control device 3 serves to control the drive device 4, which is mechanically and / or electrically connected to an electric door lock 5 (TS). The drive device 4 is consequently electrically coupled with the first handle, in particular with the outside door handle 1 and with the second handle, in particular with the inside door handle 2, as well as with the door lock 5, so that advantageously dispenses with a separate drive device for the door inner handle 2 can be.

The outside handle 1 designed as the first handle and the inside handle 2 designed as a second handle are arranged in or on a door or flap, in particular a tailgate, of a motor vehicle. Furthermore, the outside door handle 1 has a first actuating element and the inside door handle 2 has a second actuating element. In the present case, the outside door handle 1 is flush in a body, in particular in the door and / or the flap of the motor vehicle, arranged. The inside door handle 2 is also flush with a panel of the door of the motor vehicle and can be used by a user inside the motor vehicle. Both handles 1, 2 are moved by a common drive device 4 from a rest position, in which the respective handles 1.2 are flush, in a use position in which the respective handle 1, 2 are in an extended position or position, moves ,

In the following, the method according to the invention is described in order to open or close the door or flap of the motor vehicle. On the exact operation of a motor vehicle associated remote key is not discussed in detail in the present embodiment. It should be briefly mentioned here that the radio key performs a code query with another or the control device 5 when the first actuating element is actuated.

In the following, the entry procedure into the motor vehicle will be described. When the user stands in front of the locked motor vehicle, the user actuates the first actuating element, which is arranged on the outside door handle 1, by approaching the first actuating element with a body part, in particular the hand, or with the body part, in particular the hand , touched. This may be a visible to the user from the outside surface on a housing of the door outside handle 1, which is provided for example with ribs. Behind these ribs is a capacitive sensor, which is located inside the Housing the outside door handle 1 is arranged. Alternatively or additionally, this may also be an optical sensor, in particular a gesture sensor or a magnetic sensor. Upon actuation of the first actuating element by the user, which is arranged on the outside door handle 1, a signal is forwarded to the control device 3, which activates the drive device 4. Then arranged in the rest position flush in the body outside door handle 1 is transferred by means of the drive device 4 in its position of use. In this case, then both the outside door handle 1 is extended, and unlocked as the electric lock lock door lock 5 unlocked. In this position of use, the outside door handle 1 is spaced from the body, so that the user can grip or pull the outside door handle 1.

When the first actuating element is actuated, both the first handle, in particular the outer door handle 1, and the second handle, in particular the inner door handle 2, are transferred by the drive device 4 into their position of use. This can preferably be done simultaneously. After a predetermined time t, in particular if more than 10 seconds have elapsed after the use position has been reached, the first handle, in particular the outside door handle 1, and the second handle, in particular the inside door handle 2, automatically move again from the position of use by means of the drive device 4 transferred back to the rest position. Alternatively, the first handle and / or the second handle can be provided with a FederDämpfer system, so that when you release the drawn first and / or second handle this is independently transferred without the help of the drive device 4 back to its rest position, creating a anti-trap is realized, and whereby the energy costs for operating the drive device 4 can be reduced.

The Aussteigevorgang from the motor vehicle is essentially like the boarding process. However, the code request of the radio key with one or the control device 3 of the motor vehicle can be dispensed with here.

When boarding the user is inside the vehicle. When the user is in the, in particular locked motor vehicle, the user actuates the second actuating element, which is arranged on the door inner handle 2, by approaching the second actuating element with a body part, in particular the hand, or this with the body part, in particular the Hand, touched. This may be a visible to the user from the outside surface on a housing of the Türinnengriffs 2, which is provided for example with ribs. Behind these ribs is a capacitive sensor, which is arranged within the housing of the door inner handle 2. Alternatively or additionally, this may also be an optical sensor, in particular a gesture sensor or a magnetic sensor. Upon actuation of the second actuating element by the user, which is arranged on the door inner handle 2, a signal is forwarded to the control device 3, which activates the drive device 4. Then arranged in the rest position flush in the panel door handle 2 is transferred by means of the drive device 4 in its position of use. In this case, both the door inner handle 2 is then extended, and unlocked as the electric lock lock door lock 5 unlocked. In this position of use, the door inner handle 2 is spaced from the panel of the door so that the user can grasp the door inner handle 2. The user pulls on the inside door handle 2 and the door of the motor vehicle is opened. When the second actuating element is actuated during the raising operation, both the second handle, in particular the inner door handle 2, and the first handle, in particular the outer door handle 1, are transferred by the drive device 4 into their position of use. After a predetermined time t, in particular if more than 10 seconds have elapsed after reaching the position of use of the inside door handle 2, the second handle, in particular the inside door handle 2, and the first handle, in particular the outside door handle 1, from the use position again with the help of Drive device 4 automatically transferred back to the rest position.

According to an alternative to the entry and exit process described above, it can be provided that only the first handle, in particular the outside door handle 1, is transferred by the drive device 4 in its position of use and the door lock 5 is unlocked by the drive device 4 when operating the first actuating element, or that upon actuation of the second actuating element, only the second handle, in particular the door inner handle 2, is transferred by the drive device 4 in its position of use and the door lock 5 is unlocked by the drive device 4.
