Side view mirror wiper system is a wiper assembly for a vehicle door mirror which allows a user to activate a switch within the drivers compartment to send electrical current to a DC motor within the mirror housing to turn on a wiper and clear rain, dew, snow, and dust from the mirror surface to allow clear side and rear viewing through the mirrors to promote safer driving conditions.

The present invention relates to a brushless direct current electric motor (1), in particular for a wiping system, comprising: a rotor (15) comprising a control magnet, a stator (3) having electromagnetic excitation coils (9) of the rotor (15), at least one Hall effect sensor (23) configured to detect an angular position of the control magnet (21), a control unit (25) connected to said Hall effect sensor (23) and configured to determine at least one angular position of the rotor (15) in relation to the stator (3) from the signals (H) from the Hall effect sensor (23) and to generate control signals (C) to power the electromagnetic excitation coils (9) of the stator (3) as a function of the determined angular position of the rotor (15), in which the control unit (25) comprises a clock (26) and is configured to: estimate the angular position of the rotor (15) at a plurality of predetermined instants (i.sub.21 . . . i.sub.25) lying between two changes of state of the Hall effect sensor (23) from the instants (I0, I1) of the preceding changes of state, determine values of the control voltages associated with the angular positions of the rotor (15) estimated for the predetermined instants (i.sub.21 . . . i.sub.25), said voltage values making it possible to generate a substantially sinusoidal control signal (C), generate a substantially sinusoidal control signal (C) from the determined voltage values.

The invention relates also to a gear motor, a wiping system and a method for controlling the electric motor (1).

A wiper controller includes an acquirer and a determiner. The acquirer acquires a value related to an electric current flowing through a wiper motor driving a wiper reciprocating between a first position and a second position. The determiner determines that a position of the wiper is either the first position or the second position based on a temporal change of the electric current flowing through the wiper motor.

The swing member (63) to be subjected to swinging drive is integrally provided to the output shaft (56) outside the speed reducer case (52), the speed reducer case (52) is provided with a pair of swing regulating portions (61, 62) which prevents the swing member (63) from being moved beyond the wiping-allowable limit angle (b) by contacting the swing member (63). As a result, the swing member (63) and the swing regulating portions (61, 62) can collectively form the regulating member (60). As a result, essential components (such as fixing plate) can be omitted from the conventional wiper apparatus. Therefore, the wiper apparatus can be improved in assembly workability, size and weight by reducing the number of components thereof, and provided with a regulating member (60) which prevents the wiper member being moved beyond the wiping-allowable limit angle (b).

The invention relates to a wiper motor (10) for the cleaning of vehicle windows, with an output element (17) rotatable about an axis (19), wherein in the output element (17) at a distance (a) the first axis (19) a bearing mount (25) is constructed for a drive lever (30) for driving a wiper shaft (11), wherein the wiper shaft (11) is pivotably mounted in a further axis (16) arranged at least substantially parallel to the axis (19) of the output element (17), and wherein the drive lever (30) is received with an extension (35) in a clamping manner in the bearing mount (25) and extends at least substantially in a plane arranged perpendicularly to the axes (16, 19). According to the invention, it is provided that the extension (35) has a fastening region (36) in the shape of a spherical segment, which cooperates with the bearing mount (25), and that the extension (35) is pivot able about a centre point of the fastening region (36).

Disclosed embodiments relate to a windscreen wiper drive of a windscreen wiper device of a rail vehicle. The drive includes at least one electric motor, a gear, the input shaft of which being connected to an output shaft of the electric motor, wherein an output shaft of the gear is provided for driving at least one windscreen wiper arm of a windscreen wiper, which arm swings back and forth with the output shaft, a rotation angle sensor unit, which detects a rotation of at least one element of the windscreen wiper drive, and a mechanical rotation angle limitation, which mechanically limits a rotational movement of at least one element of the windscreen wiper drive. The electric motor is formed by a disc motor and the gear is formed by a planetary gear.

A motor vehicle windshield wiper system includes a windshield wiper and a controller. The controller is configured, in response to a threat of freezing precipitation, to park the windshield wiper in a parked position with a first end of the windshield wiper oriented toward a top edge of the windshield and a second end of the windshield wiper oriented toward a bottom edge of the windshield. A related method of minimizing ice and snow buildup on a windshield wiper is also disclosed.

A support structure for a front wiper device for a vehicle having an annular pivot cap which surrounds, under a deck garnish, a periphery of a pivot on which a base end portion of a wiper arm is supported is provided. The pivot cap includes a bottom plate section that is in an annular shape surrounding the periphery of the pivot, and is extended to a vehicle front side, and a flange section extending upward from an edge portion of the bottom plate section. The flange section is opened at a vehicle front side, and is provided with an opening. In a region at a vehicle rear side and at an electric motor side, of the bottom plate section, a protrusion that protrudes upward from a region at a side opposite to the electric motor is included.
