,TagSPECI:TECHNICAL FIELD
The present disclosure relates to warning system. In particular, embodiments disclose reverse gear warning system to generate a warning signal by the frontal vehicle horn when the reverse gear of the vehicle is engaged.
BACKGROUND OF DISCLOSURE
It is a mandatory law in many countries to have a warning device such as a horn in vehicles to warn the others of the approach of the vehicle or to alert the presence of a vehicle. Almost all the vehicle manufacturers mandatorily install frontal warning systems such as a vehicular horn.
Many of the auto manufacturers also install a reverse warning system such as audio warning indicators or musical warning system or buzzers to warn or alert the presence of a vehicle while it is reversing. Several automobiles install aftermarket warning instruments which are equipped at the rear end of the vehicle which offer variety of audio warnings in different tones, frequencies and amplitudes.
Some of the warning systems installed in the vehicles do not have an option to deactivate the system when the user does not see any requirement of the warning. At times like these, the warning system becomes an unnecessary nuisance to the public. Some of the aftermarket warning instruments installed in the vehicles have a high pitch frequency and amplitude of the warning tone which causes irritation to the onlookers and also increases the noise pollution in the environment.
Moreover, the warning systems installed in the vehicles cannot be activated or deactivated as per the user’s requirement. If the warning system installed in the vehicle is an aftermarket installation kit, this leads to workshop modification of the car electronics which may hinder or short circuit the electronics of the vehicle.
In light of the above, there is a need to provide a warning system in the vehicle which will detect the engagement of a reverse gear of the vehicle by generating a warning signal using only the frontal vehicle horn. Also, the warning signal generated by the vehicle horn would be regulated accordingly based on the situation and user’s requirement.

OBJECTIVES OF THE DISCLOSURE
One objective of the present disclosure is to generate a warning signal by using only the frontal vehicle horn when a reverse gear of the vehicle is engaged.
Another objective of the present disclosure is to regulate the frequency and amplitude of the vehicle horn by a regulating unit installed in a control unit of the vehicle.
Another objective of the present disclosure is to regulate the frequency and amplitude of the vehicle horn to a low pitch or a high pitch by the regulating unit installed in the control unit of the vehicle.
Another objective of the present disclosure is to provide a sensor at the rear end of the vehicle which detects any obstacle and generates signals to the control unit for regulation of the vehicle horn to a low pitch and a high pitch.
Another objective of the present disclosure is to provide a control switch in the vehicle to control the activation and deactivation of the warning system.

DETAILED DESCRIPTION OF THE DISCLSOURE

The foregoing has broadly outlined the features and technical advantages of the present disclosure in order that the detailed description of the disclosure that follows may be better understood. Additional features and advantages of the disclosure will be described hereinafter which form the subject of the claims of the disclosure. It should be appreciated by those skilled in the art that the conception and specific embodiment disclosed may be readily utilized as a basis for modifying or designing other structures for carrying out the same purposes of the present disclosure. It should also be realized by those skilled in the art that such equivalent constructions do not depart from the spirit and scope of the disclosure as set forth in the appended claims. The novel features which are believed to be characteristic of the disclosure, both as to its organization and method of operation, together with further objects and advantages will be better understood from the following description when considered in connection with the accompanying figures. It is to be expressly understood, however, that each of the figures is provided for the purpose of illustration and description only and is not intended as a definition of the limits of the present disclosure. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the figures, can be arranged, substituted, combined, and designed in a wide variety of different configurations, all of which are explicitly contemplated and make part of this disclosure.

Referring now to the drawings wherein the drawings are for the purpose of illustrating an exemplary embodiment of the disclosure only, and not for the purpose of limiting the same.
Figures 1 and 2 illustrates block diagram of the warning system (100) integrated into a vehicle (1). The vehicle (1) installed with the warning system (100) first detects the position of the gear lever. On engagement of the reverse gear of the vehicle (1), a control unit (2) which is configured in the vehicle (1) detects the engagement of the reverse gear of the vehicle (1). When the user engages the reverse gear, the reverse lamp switch (8) gets activated and the warning lamp provided at the rear end of the vehicle gets activated. The control unit (2) has an inbuilt regulating unit (5) which regulates the frequency and amplitude of the vehicle horn (4) to a low pitch frequency. The warning system (100) equipped in the present disclosure utilizes the frontal vehicle horn (4). The control unit (2) is connected to a reverse lamp switch (8) which on engagement of the reverse gear activates the visual lamp, which acts as the visual warning for the vehicle (1). Also, the reverse lamp switch (8) will provide electrical signal to the left turn indicator (11) and right turn indicator (12) only to the rear end of the vehicle (1) which start flashing sequentially providing a hazard warning signal. Therefore in the present disclosure, engagement of the reverse gear (3) will activate the reverse warning lamp along with the rear left and right turn indicators (11, 12) of the vehicle (1).
In an exemplary embodiment of the present disclosure, the control unit (2) is connected to a control switch (6) through which the user can activate or deactivate the warning system based on the requirement. The control switch (6) is provided at the reach of a user such as in the cabin of the vehicle (1) to control the activation and deactivation of the warning system.
In an exemplary embodiment of the present disclosure, a sensor (7) is installed at the rear end of the vehicle (1), wherein the sensor (7) detects any obstacle behind the vehicle (1). When the sensor (7) detects an obstacle in close proximity to the vehicle, a first signal (10) is given to the control unit (2), wherein the regulating unit (5) regulates the frequency and amplitude of the vehicle horn (2) to a high pitch warning signal.
In Figure 2, the flow chart of the logic of working of the warning system (100). The control unit (2) first detects the reverse gear engagement of the vehicle (1) by the user. When the reverse gear is engaged, a signal is received by the control unit (2). The control unit (2) is integrated with a regulating unit (5), wherein on engagement of a reverse gear, electrical signal will be given to the reverse lamp switch (8) which illuminates the reverse lamp which acts as a reverse visual warning signal. Further, the regulating unit (5) will regulate the frequency and amplitude and generate a regulated signal. The control unit (2) transmits the regulated signal to the vehicle horn (4) which will generate the reverse warning signal from the vehicle horn (4) to a low pitch audio warning signal. The regulating unit (5) has an inbuilt power resistor (not shown in figure) which regulates the amplitude in the generated signal.
In an embodiment of the present disclosure, a control switch (6) is connected to the control unit (2) through which the end user can activate or deactivate the warning system based on the requirement. If the user has engaged the control switch (6), the warning system (100) will continuously generate the warning signal in a low pitch during the operation of the vehicle (1). If the end user has disengaged the control switch (6), the warning system (100) will not generate any warning signal.
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 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 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. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
