    摘要： In order to ensure, when the drive (1) is in a non-operating state, a self-locking that counters a change in position of the wiper (5), an electronically implemented self-locking is provided. To this end, the controller (S) of the wiper system monitors the wiper (5) during the non-operating state of the drive (1) by evaluating the position sensor signals for a change in position and, in response to the position monitoring, activates the drive (1) in order to return the wiper (5) into a set position (U, P).

    摘要： A vehicle rain sensor system for detecting precipitation on an exterior surface of a window (19) including an illumination sensor (36) that is decoupled from the window. The illumination sensor is preferably an imaging array sensor which communicates a signal control (42) which further determines whether rain is present on the window. The control preferably includes an edge detection (44) for detecting edges of precipitation droplets on the window and activating the windshield wipers (22) of the vehicle when the number of edges detected exceeds a predetermined threshold value. The rain sensor system may further include a polarizing filter (62) and an illumination source (55), such that rain sensor system may not only prevent false signals of rain when only fog is present on an interior surface (28) on the window, but also allows the rains sensor system to actually detect fog particles on an interior surface on the window, thereby allowing the control to further be connected to a ventilation blower within the vehicle for the purpose of activating the blower to eliminate the fog.

    摘要： The invention concerns a method for controlling a wiper motor of a wiper device for a motor vehicle windshield. The invention also concerns a control unit implementing the inventive method and a wiper device for a motor vehicle windshield. The invention is characterised in that the control unit (20) produces a control of the electric motor (19) which powers a wiper blade (15) on a windshield sweeping between two end-of-travel test zones. In each end-of-travel zone, there is a software end-of-travel stop which is moved by a predetermined value after each passage on the software stop, the latter always remaining in it test zone, thereby providing self-adaptation of the sweeping limits in time. The invention also enables to detect the presence of obstacles on the wiper blade path.

    摘要： The invention relates to a windscreen wiper system comprising two opposed wipers (1, 2), each of which can be driven by means of a separate motor (M FS, M BS). A control unit (7) is provided in order to control the motors (M FS, M BS) independently of one another using control signals. According to the invention, the motors (M FS, M BS) of the wipers (1, 2) are controlled by the control unit (7) in order to define a temporally dependent angular position of the wipers in accordance with a trigonometric function φ(t).

    摘要： A spindle (249) and a position-limiting ridge (50) protrude from an inner surface (221) of a cover (22) to rotatably support a follower (23) made of an electrically conductive metal plate. A cylindrical engaging portion (232) of the follower (23) slidably engages the spindle (249). A toothed washer (51) is fitted around the spindle (249) to clamp a contact portion (236) of the follower (23) between the position-limiting ridge (50) and the toothed washer (51) in a rotatable manner. A switching pattern (26) is provided in the inner surface (221) of the cover (22). Contact terminals (231) that engage and disengage with the switching pattern (26) based on rotation of the follower (23) are integrally formed in the follower (23). An engaging hole (24) penetrates through the follower (23). An engaging protrusion (25) on a carrier (19) is received within the engaging hole (24). The follower (23) is rotated through engagement between the engaging protrusion (25) and the engaging hole (24) when the carrier (19) rotates in a forward rotational direction (R).
