Nationality: Indian
The following specification particularly describes the invention and the manner in which it is to be performed.

TECHNICAL FIELD
Present disclosure, in general, relates to a field of automobiles. Particularly, but not exclusively, the present disclosure relates to controlling an operation of a wiper assembly of a windshield. Further, embodiments of the present disclosure relate to a method of controlling the wiper assembly based on position of the wiper assembly.
BACKGROUND OF THE DISCLOSURE
Generally, vehicles are equipped with a wiper assembly to sweep a windshield. The wiper assembly includes a wiper base connected to a body of the vehicle, where the wiper base includes an electric motor. Further, a wiper arm is connected to the wiper base and rotatable about the wiper base. The wiper arm includes a wiper blade that is always in contact with the windshield and selectively sweeps the windshield of a vehicle due to rotation of the wiper arm about the wiper base. The wiper assembly is often actuated either manually by hand from an occupant of the vehicle or automatically by a powered source such as the electric motor in order to clear the windshield of obstructive particles such as dust, fog, snow and the like covering field of view of a driver and/or a passenger in the vehicle.
Usually, the wiper blades have short service life is typically short and may require replacement every now and then. The blades are prone to damage due to atmospheric conditions including temperature changes, dust and/or dirt accumulation at interface of the wiper blade and the windshield as long as the blade is in contact with the windshield. To avoid damage to the blade of the wiper assembly, the wiper assembly is manually lifted by pivoting the wiper arm about the wiper base from the windshield when the vehicle is not in use. Manual lifting of the wiper blade from the windshield requires a passenger and/or driver to step out of the vehicle which is tedious, inconvenient and may not be possible under some conditions or in many occasions the user may forget to lift the wiper blade above the windshield.
Conventionally, a control system to selectively lift and forcefully drop the wiper onto the windshield to disperse accumulated snow on windshield of a vehicle is known. The wiper is raised to a substantial height from the windshield and is suddenly dropped by the control system onto the windshield to clear the accumulated snow on the windshield. Such control systems avoid the user from coming out of the interior of the vehicle to clear the snow accumulated on the windshield. However, such control systems may not be suitable to completely avoid contact of the wiper assembly with the windshield in conditions such as parked condition and the like.

The present disclosure is directed to overcome one or more limitations stated above or any other limitations associated with the conventional mechanisms.

Further, the electric linear actuator may be configured to pivot the wiper arm (5) about the wiper base (4) toward the windshield (9) by retracting the plunger (2a), thereby lowering the wiper arm (5) along with the wiper blade (6) towards the windshield (9)

for sweeping the windshield (9) upon being actuated by the control unit (3) based on the at least one second signal indicative of the operative position.
Referring now to Figures 2c and 2d, the actuator (2) may include at least one feedback sensor positioned within the wiper assembly (1) to detect contact of the wiper assembly (1) with the windshield (9) while the actuator (2) may be actuated to lower the wiper assembly (1). In an embodiment, the at least one feedback sensor may include a hall effect sensor, an optical sensor and the like. The at least one feedback sensor may detect a gap formed between the wiper assembly (1) and the windshield (9) due to wear and tear of the wiper blade (6), as can be seen in Figure 2c, and may be configured to transmit at least one feedback signal to the control unit (3). The control unit (3) may be configured to actuate the actuator (2) to pivot and lower the wiper assembly (1) so as to compensate for the gap, as can be seen in Figure 2d, detected by the at least one feedback sensor, to thereby avoid improper cleaning of the windshield (9) due to wear and tear of the wiper blade (6) in the operative condition. In an embodiment, lowering of the wiper blade (6) upon receiving the at least one feedback signal may allow the wiper blade (6) to sweep the windshield (9) with a predetermined pressure, thus ensuring proper sweeping of the windshield (9). In an exemplary embodiment, the predetermined pressure may range between 0.1 kPa to 0.3 kPa. Further, the pressure distribution by the wiper blade (6) may vary along the length of the wiper blade (6) based on the structure of the wiper blade (6) and the type of contact established between the wiper blade (6) and the windshield (9). The predetermined pressure is subject to change based on the material of the wiper blade (6) and the way it is engaged with the windshield (9).
Referring now to Figures 2a and 2b, which illustrate different configurations of the system (100) for operating a wiper assembly (1) in the operative condition and the non-operative condition. The wiper assembly (1) may be configured to engage with the windshield (9) to selectively sweep the windshield (9) in the operative condition as can be seen in Figure 2a. The control unit (3) may be configured to actuate the actuator (2) to lift the wiper blade (6) to a predetermined height from the windshield (9) upon receiving at least one second signal. The wiper blade (6) may be pivoted about the wiper base (4) thereby displacing from the windshield (9) to a predetermined height of 4.5mm to 6.5 mm to avoid contact of the wiper blade (6) the windshield (9) as best seen in Figure 2b. With such configuration, the system (100) may automatically lift the wiper assembly (1) from the windshield (9) based on operative condition

of the wiper assembly (1) and damage to the wiper blades of the wiper assembly (1) due to contact with the windshield (9) may be minimized or eliminated.

EQUIVALENTS
With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system (100) having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C,

etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system (100) having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
In addition, where features or aspects of the disclosure are described in terms of Markush groups, those skilled in the art will recognize that the disclosure is also thereby described in terms of any individual member or subgroup of members of the Markush group.
While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art.
