The invention relates to a shading device (1), in particular a sunscreen roller blind, for a vehicle roof, comprising at least one length of sunshade (10) which can be rolled up for shading a light-permeable and/or open area of the vehicle roof (2), a tension bow (11) which is movable in a direction of travel (V) and to which the length of sunshade (10) is fastened, a drive mechanism (13) which can be actuated by a drive motor (12) and is designed to move the tension bow (11) back and forth between a first end position (P1), in which the length of sunshade (10) is unrolled, and a second end position (P2), in which the length of sunshade (10) is at least partially unrolled, a control unit (14) for controlling the drive motor (12), the shading device (1) comprising at least one opposing force element (15), in particular a stop element, for limiting a travelling movement of the tension bow (11), the control unit (14) being designed to control, in particular to deactivate, the drive motor(12) on the basis of an opposing force, in particular a stop force, and/or a driving torque of the drive motor (12) when the tension bow (11) reaches an end position (P1, P2) defined by the stop element (15). The invention further relates to a roof arrangement (100), in particular a sliding and/or lifting roof arrangement, having a corresponding shading device (1), and to a control method for a shading device (1).

    本发明涉及一种用于车辆车顶的遮蔽装置(1)、尤其遮阳卷帘,其包括:至少一个可以卷起的遮蔽长度段(10),用于遮蔽车辆车顶(2)的透光和/或敞开区域;在行进方向(V)上可移动地安装的张紧弓形件(11),遮蔽长度段(10)紧固到所述张紧弓形件(11)上;可以由驱动马达(12)操作的驱动机构(13),所述驱动机构被设计成使张紧弓形件(11)在遮蔽长度段(10)被卷起的第一端部位置(P1)与遮蔽长度段(10)至少部分地展开的第二端部位置(P2)之间来回移动;用于操控驱动马达(12)的控制单元(14),其中,遮蔽装置(1)包括至少一个反作用力元件(15),尤其止动元件,用于限制张紧弓形件(11)的行进运动,其中,控制单元(14)被设计成当张紧弓形件(11)到达由止动元件(15)限定的端部位置(P1、P2)时,基于反作用力、尤其止动力和/或驱动马达(12)的驱动转矩来操控、尤其关闭驱动马达(12)。此外,本发明涉及一种车顶布置(100)、特别涉及一种具有相应的遮蔽装置(1)的滑动和/或升降车顶布置,以及还涉及一种用于遮蔽装置(1)的控制方法。
