Description:
CROSS-REFERENCE TO RELATED APPLICATION 
       [0001]    This application claims priority to German Patent Application No. 102014016570.1, filed Nov. 8, 2014, which is incorporated herein by reference in its entirety. 
       TECHNICAL HELD 
       [0002]    The present disclosure pertains to a door for a vehicle with an integrated control panel for controlling actuators such as, for example, servomotors of an exterior rearview mirror that are arranged on the door or at other locations of the vehicle. 
       BACKGROUND 
       [0003]    A vehicle door of this type is known from DE 10 2005 036 001 A1, which addresses the problem of comfortably controlling functionally identical actuators provided in several sets at different locations of the motor vehicle such as, for example, actuators of a left and a right exterior, rearview mirror, power windows or seat adjusters, with a limited number of control elements. In particular, a selection control element is used to select one of several functionally identical actuators, with a control element, by means of which the motions of the respectively selected actuator can be controlled. In this way, one and the same control element can serve for successively controlling different actuators. This is particularly advantageous if the actuator has several degrees of freedom of motion as it is the case with an exterior rearview mirror because the control element for such an actuator is relatively expensive and has a substantial space requirement. However, this conventional concept cannot be used in instances, in which several functionally dissimilar actuators have to be controlled and their potential motions cannot be intuitively associated with the degrees of freedom of the assigned control element. 
       SUMMARY 
       [0004]    In accordance with the present disclosure, a door for a motor vehicle is provided with an integrated control panel that also enables comfortable control of functionally dissimilar actuators within a confined space. 
         [0005]    According to an embodiment of the present disclosure, a vehicle door features a control panel arranged on the inner side thereof. The control panel is realized in the form of a touchscreen that can be switched over between at least two display modes. The touchscreen displays a first control element for controlling a first actuator of the vehicle in the first display mode and a second control element for controlling a second actuator, which is dissimilar from the first actuator, in the second display mode. The touchscreen makes it possible to respectively realize the different control elements dissimilar such that their potential controls can be intuitively associated with the potential motions of the actuators. The respectively displayed control element furthermore enables the user to ascertain the current display mode of the control panel and whether an actuation of the displayed control element can lead to the desired reaction or the control panel initially needs to be switched over into a different display mode. 
         [0006]    If the number of display modes is small, a selection control element may be additionally displayed in each display mode. This selection control element can be actuated by the user in order to switch into another display mode assigned to the respective selection control element. Alternatively, a selection mode may be provided, in which the control panel displays at least one selection control element for selecting between the first and second display modes. 
         [0007]    The actuators controlled by means of the control panel may fulfill various functions in the motor vehicle. For example, they may control the position of an exterior rearview mirror, a seat or a side window, but they may also open or close a door, a hood or trunk lid or a fuel door of the vehicle, as well as lock and unlock such components in the closed position. 
         [0008]    In the first and the second display modes, a symbol specific to the respectively active display mode should be visible on the touchscreen such that the user can at all times ascertain which actuators can be controlled in the current display mode. In order to select between functionally identical actuators, the touchscreen may in the first display mode display a selection control element, by means of which the first actuator of a plurality of actuators can be selected. 
         [0009]    The touchscreen may be integrally installed into the door. According to an advantageous enhancement, the touchscreen forms part of a mobile device that is removably accommodated in a mount of the vehicle door. Due to its small dimensions on the one hand and its widespread use on the other hand, a smartphone may be considered as such a mobile device. 
         [0010]    Since a broad variety of different models of such devices are in use, the mount should include an exchangeable adapter for accommodating the mobile device in a form-fitting fashion. 
         [0011]    A charging socket for charging a rechargeable battery of the mobile device is well suited for promoting the willingness of the user to place the respective mobile device into the mount. If the mobile device is a mobile telephone, it should be connected to a hands-free speakerphone when it is positioned in the mount. In this way, it can be simultaneously ensured that a user, who uses the telephone while driving, complies with the applicable laws by carrying on the conversation via the hands-free speakerphone. 
         [0012]    The mobile device should be designed for automatically detecting when it is accommodated in the mount. Such a detection may serve different purposes such as, for example, automatically linking the mobile telephone and the hands-free speakerphone. In the context of the present disclosure, the detection of the mobile device being accommodated in the mount particularly should serve to switch the touchscreen into one of the above-described display modes. 
         [0013]    The display mode of the touchscreen may furthermore be switched over in accordance with a state of motion of the vehicle. In this context, particularly a display mode that allows the control of doors, hatches or the fuel door of the vehicle may be blocked while the vehicle is in motion in order to preclude an inadvertent actuation of these elements by the user.

     DETAILED DESCRIPTION 
       [0023]    The following detailed description is merely exemplary in nature and is not intended to limit the invention or the application and uses of the invention. Furthermore, there is no intention to be bound by any theory presented in the preceding background of the invention or the following detailed description. 
         [0024]      FIG. 1  shows the lower part of a door  1  of a motor vehicle, in this case the driver&#39;s door, viewed from its inner side. Interior trim panel  2  of plastic conventionally covers large sections of the door panel. An armrest  3  is formed in a central region of the interior trim panel  2 . A handle  5  extends obliquely upward from the horizontal upper side  4  of the armrest  3 . A control panel in the form of a touchscreen  6  is arranged in the upper side  4  at the base of the handle  5 . 
         [0025]    The touchscreen  6  and an assigned control unit may be integrally installed in the door  1 , The control unit acts as display driver for the touchscreen  6 , detects when and where the touchscreen  6  is contacted by a finger of the user and outputs control commands to actuators of the vehicle derived from the finger contact. 
         [0026]    In the example illustrated in  FIG. 2 , only a recess  7 , in which an adapter  8  is detachably accommodated, is integrated into the upper side  4  of the armrest. The adapter  8  in turn features a recess  9  that is adapted to the shape of a smartphone  10  placed therein for holding the smartphone in a form-fitting fashion. The touchscreen of the smartphone serves as the above-described touchscreen  6  and its processor serves as the display driver. 
         [0027]    A charging socket  11  of the adapter is coupled to the smartphone  10  in order to connect the smartphone to the vehicle battery and charge its rechargeable battery. The charging socket  11  typically includes a USB connection between the smartphone  10  and other users of an internal network of the vehicle so as to allow data communication there between. When the smartphone is inserted into the recess  9 , for example, such a communication with another user enables the smartphone  10  to detect that it is located in a vehicle, as well as to subsequently establish a link with a hands-free speakerphone of the vehicle on the one hand and to start a utility program described in greater detail below with reference to  FIGS. 3-8  on the other hand. 
         [0028]    An edge of the recess  9  located opposite of the charging socket  10  is in this case formed by a latch  13  that is rotatable about an axis  12  extending perpendicular to the plane of section. The latch encompasses the smartphone  10  in a form-fitting fashion in its position illustrated with continuous lines in  FIG. 2  and can be pivoted in the clockwise direction about the axis  12  into an orientation illustrated with broken lines, in which the smartphone  10  is lifted out of the recess  9  by an arm  15  of the latch  13  and can be removed by the user, via pressing on an actuating surface  14 . 
         [0029]    When the smartphone  10  is inserted into the recess  9  by the user while the vehicle is at a standstill and the smartphone  10  detects this, for example, based on the communication with another user of the vehicle network via the charging socket  11 , it initiates an application program, in which it can serve as control element for various actuators of the vehicle. 
         [0030]    According to an embodiment, the application program starts with a selection control mode, in which various selection control elements  16 - 19  are defined on the touchscreen  6  as illustrated in  FIG. 3 . A user contacting one of these selection control elements  16 - 19  with a finger is respectively interpreted as inputting a selection command. The boundaries of the control elements  16 - 19 , which are illustrated with broken lines in  FIG. 3 , do not have to be visible on the touchscreen  6 . However, symbols  20 - 23  are visible within the boundaries of the control elements  16 - 19  and intuitively reveal to the user which actuators can be accessed with the different control elements  16 - 19 . For example, the servomotors of exterior rearview mirrors of the vehicle are indicated with the symbol  20 , power windows with the symbol  21 , servomotors of a seat, typically the driver&#39;s seat, with the symbol  22  and a fuel door locking mechanism with the symbol  23 . Other control elements and symbols may serve for locking doors, a hood or trunk lid of the vehicle or, particularly in the case of a trunk lid, for actuating a servomotor that drives the trunk lid motion. 
         [0031]    The link with the on-board network of the vehicle enables the smartphone  10  to detect when the vehicle begins to move. It would be conceivable that individual selection control elements are deactivated when the vehicle is in motion and the symbols assigned thereto preferably are also no longer displayed. This may concern, for example, the control element  19  for the fuel door locking mechanism, which preferably should not be actuatable while the vehicle is in motion. Unlocking or adjusting the hood or trunk lid should also be prevented while the vehicle is in motion. 
         [0032]    When the selection control element  16  is actuated, the touchscreen  6  switches over into a first control mode illustrated in  FIG. 4 . The control elements  24 ,  25  make it possible to select a left or a right exterior rearview mirror of the vehicle. If applicable, a color change of the corresponding control element  24  or  25  may indicate which of the two exterior rearview mirrors has been selected. 
         [0033]    Four additional control elements  26  are defined at the points of an arrow cross  27  illustrated on the touchscreen  6 . Two opposite control elements  26  control pivoting motions of the respectively selected exterior rearview mirror about one of two pivoting axes in respectively opposite directions. A control element  28  in the center of the arrow cross  27  may be provided for jointly retracting and extending the exterior rearview mirrors. 
         [0034]    A control element  29  may be provided for returning to the selection mode according to  FIG. 3 . Alternatively, the return to the selection mode could also take place when no contact of the touchscreen  6  by the user is detected during a predefined waiting or idle period or, for example, a command gesture such as a swiping motion over a large portion of the touchscreen is detected instead of the user tapping on an individual control element. 
         [0035]    A second control mode illustrated in  FIG. 5  is activated by actuating the selection control element  17 . Four selection control elements  30  on the corners of the touchscreen  6  are assigned to the four doors of the vehicle and enable the user to specify on which door a power window should be opened or closed by means of large-surface control elements  31  that are centrally positioned on the touchscreen  6 . 
         [0036]      FIG. 6  shows the touchscreen  6  in a control mode that can be selected by means of the selection control element  18  according to  FIG. 3 . In this case, control elements  33 ,  34  are superimposed on a schematic top view of the driver&#39;s seat  32 . The control elements  33  illustrated on the seating surface control a forward or backward motion of the entire seat  32  and the control elements  34  illustrated on the backrest control the inclination of the latter. Although the driver&#39;s seat  32  has in this case two degrees of freedom of motion analogous to the exterior rearview mirrors, the arrangement of the control elements  26  illustrated in  FIG. 4  would not allow an intuitive control of the driver&#39;s seat  32 . The touchscreen  6  makes it possible to always position and, if applicable, combine the control elements with explanatory symbols such as, e.g.,  27  or  32  in such a way that an intuitive control can be realized. 
         [0037]    The control mode illustrated in  FIG. 7  can only be selected by means of the selection control element  19  when the vehicle is at a standstill. The symbols  36 ,  37 ,  38  assigned to the control elements  35  in this mode respectively refer to the functions of the corresponding control elements  35  for unlocking a hood, a fuel door or a trunk lid. They may change their appearance depending on the state of actuation, e.g., in that the hood illustrated with broken lines in the symbol  36  is illustrated with continuous lines as soon as the corresponding control element has been actuated and the hood has been unlocked. 
         [0038]      FIG. 8  shows another control mode, in which a schematic top view of the passenger compartment of the vehicle is displayed on the touchscreen  6 . In this case, the illustrations of the doors  39  serve as symbols that mark the position of control elements  40 , by means of which the respective locking mechanism of the corresponding door is controlled. Another control element  41  may be superimposed on the illustration of the rear seats in order to activate and deactivate a child safety lock on the rear doors. 
         [0039]    While at least one exemplary embodiment has been presented in the foregoing detailed description, it should be appreciated that a vast number of variations exist. It should also be appreciated that the exemplary embodiment or exemplary embodiments are only examples, and are not intended to limit the scope, applicability, or configuration of the invention in any way. Rather, the foregoing detailed description will provide those skilled in the art with a convenient road map for implementing an exemplary embodiment, it being understood that various changes may be made in the function and arrangement of elements described in an exemplary embodiment without departing from the scope of the invention as set forth in the appended claims and their legal equivalents.
