TECHNICAL FIELD
[001] Present disclosure, in general, relates to a field of automobiles. Particularly, but not exclusively, the present disclosure relates to a tipper vehicle. Further, embodiments of the present disclosure discloses a method and a system for stabilizing the tipper vehicle during tipping operation.
BACKGROUND OF THE DISCLOSURE
[002] Generally, tipper vehicles comprises a load body which is configured to carry payload and a lift axle which may be employed when the tipper vehicle is loaded with the payload. The tipper vehicles are configured to tip or tilt the load body by elevating one end of the load body for unloading the payload. For example, a forward end of the load body elevates as it pivots about an axis parallel to an axle of the load body and the payload is unloaded from a rear side of the load body. During tipping of the load body, conventional tipper vehicles are subjected to instability, which may lead to toppling of the tipper vehicle. That is, during pivoting the load body to offload the payload, center of gravity of the tipper vehicle is shifted towards a rear side of the vehicle and leads to tipping over of the vehicle.

[024] Fig. 1 illustrates block diagram of a system (100) for stabilizing a tipper vehicle [not shown in Figs] during tipping operations. The tipper vehicle [hereafter interchangeably referred to as vehicle] may include a front axle and a rear axle which may be disposed rearward of the front axle. In an embodiment, the vehicle may include one rear axle or a plurality of rear axles depending on configuration of the vehicle. Further, the vehicle may include a lift axle. In an embodiment, the front axle, the rear axle and the lift axle are adapted to be fixed with wheels. In an embodiment,

the lift axle may be disposed between the front axle and the rear axle. The lift axle may be lifted away from and lowered onto to the ground based on requirement. In an embodiment, the lift axle may be lowered to the ground when the payload is received by the load body (i.e., in laden condition) and may be lifted from the ground when the payload is unloaded (i.e., in unladen condition) from the load body.
[025] In an embodiment, the lift axle may be equipped with one or more lifting members which may be adapted to lift and lower the lift axles based on requirement. In an embodiment, one or more the lifting members may be but not limiting to air bellows, a piston cylinder arrangement and the like. Further, the lift axles may be equipped with a lift axle suspension bellow (4) which may be adapted to perform suspension operations for the lift axle and also carry loads acting on the lift axle. In an embodiment, the lift axle may include a plurality of lift axle suspension bellows (4) for performing the suspension operations and carry loads, when the lift axle is deployed, i.e., lowered to and in contact with the ground. In an embodiment, the lift axle suspension bellow (4) and the one or more lifting member which may be associated with the lift axles may be operated by at least one of pneumatic and hydraulic means. That is, the lift axle suspension bellow (4) and the one or more lifting members may be operated by supplying fluids at predefined pressure.
[026] Further, the vehicle may include a chassis which may be supported on the front axle and the rear axle. Furthermore, the vehicle may include a load body which may be disposed on the chassis. The load body may be adapted to carry the payload and may be adapted to tip relative to the chassis to unload the payload. Additionally, the vehicle may include the system (100) for stabilizing the vehicle during tipping operations.
[027] The system (100) may include an angle sensor (1) which may be coupled to the load body. In an embodiment, the angle sensor (1) may be including but not limited to a hall effect sensor, a potentiometer, a capacitive sensor and the like. The angle sensor (1) may be configured to determine tipping angle of the load body. Further, the system (100) may include a valve (3) which may be fluidly coupled to the lift axle suspension bellow (4). The valve (3) may be adapted to regulate the pressure in the lift axle suspension bellow (4). In an embodiment, the valve (3) may be fluidly connected to a fluid source [not shown in Figs] and may be configured to supply fluid into and out of the lift axle suspension bellow (4). In an embodiment, the valve (3) may be a

pressure relief valve, a solenoid valve and the like. In an embodiment, the system (100) may include a single valve (3) for multiple lift axle suspension bellows (4) or may include one valve (3) corresponding to each lift axle suspension bellow (4) in the vehicle.
[028] Furthermore, the system (100) may include a pressure sensor (2) which may be coupled to the lift axle suspension bellow (4) and may be configured to determine pressure of fluid in the lift axle suspension bellow (4). In an embodiment, the pressure sensor (2) may be directly coupled to the lift axle suspension bellow (4) or may be coupled to any fluid line which is in fluid communication with the lift axle suspension bellow (4). As an example, the pressure sensor (2) may be including but not limited to resistance strain gauge pressure sensor, semiconductor strain gauge pressure sensor, piezoresistive pressure sensor, inductive pressure sensor, capacitive pressure sensor, resonant pressure sensor and the like. Additionally, the system (100) may include a controller (5) which may be communicatively coupled to the angle sensor (1), the pressure sensor (2) and the valve (3). The controller (5) may be configured to selectively regulate pressure in the lift axle suspension bellow (4) corresponding to tipping of the load body to stabilize the vehicle during tipping operation.
[029] In an embodiment, the controller (5) may be an electronic control unit (ECU) of the vehicle. In an example, the controller may be the ECU that controls the operation of the lift axle, and may also be referred to as the lift axle control unit (LACU). In another example, the controller may be dedicated to perform the functions to achieve the tipping stability as described herein, and may be coupled to the LACU to achieve the functions. The controller (5) may also communicate with other ECUs of the vehicle. Further, the system (100) may include a memory unit [not shown in Figs] which may be integrated with the controller (5) or may be a separate unit which may be communicatively coupled to the controller (5). In an embodiment, the controller (5) may include the memory unit which may be configured to store data. The memory unit may be configured to store a predetermined pressure for corresponding tipping angles. That is, the memory unit may include pre-stored data to determine the amount of pressure that may be required in the lift axle suspension bellow (4) for a corresponding tipping angle of the load body during unloading the payload.

[030] Further, in an embodiment, the controller (5) may be configured to receive the signals from the angle sensor (1), the pressure sensor (2), the valve (3), the memory unit and the like. That is, the controller (5) may be configured to receive the angle information from the angle sensor (1), receive the pressure from the pressure sensor (2) and for determines pressure that is to be present in the lift axle suspension bellow (4) for the received tipping angle of the load body, to stabilize the vehicle during the tipping operation. In an embodiment, the controller (5) may regulate pressure in the lift axle suspension bellow (4) by receiving real-time feedback of pressure in the lift axle suspension bellow (4) from the pressure sensor (2).
[031] In an operational embodiment, the system (100) enables regulating pressure in the lift axle suspension bellow (4) corresponding to tipping angle of the load body. Such a regulation stabilizes the vehicle. Upon tipping, the controller (5) may receive the tipping angle of the load body from the angle sensor (1). Further, the controller (5) may be configured to simultaneously receive pressure in the lift axle suspension bellow (4), from the pressure sensor (2) during the tipping operation. The controller (5) upon receiving the tipping angle from the angle sensor (1), may be configured to determine pressure which is to be present in the lift axle suspension bellow (4) for the received tipping angle of the load body. The controller (5), upon determining pressure that is to be present, may regulate pressure in the lift axle suspension bellow based on the determination. The regulation of pressure in the lift axle suspension bellow (4) relative to the tipping of the load body, facilitates in stabilizing the vehicle during unloading operations or tipping operations, as will be explained below:
[032] The controller (5) decreases pressure in the lift axle suspension bellow (4) by receiving real-time feedback of pressure in the lift axle suspension bellow (4) from the pressure sensor (2) relative to the tipping angle received from the angle sensor (1). The decrease in pressure in the lift axle suspension bellow (4) relative to the tilting operation of the load body may transfer some of the load previously exerted on the lift axle to the front axle of the vehicle. Thus, by reducing the pressure in the lift axle suspension bellow (4), the load on the front axle is increased, thereby redistributing the load between the front and the rear axles. The redistribution is such that a ratio of the load on the front axle to the load on the rear axle is increased. Thus, the instability that may otherwise be caused due to majority of loads acting on the rear axles is mitigated, and stabilizes the vehicle. The increased stability due to the regulation of pressure in the lift axle suspension

bellow (4) mitigates tipping over of the vehicle during unloading the payload. Additionally, such stability which may be facilitated due to regulation of pressure in the lift axle suspension bellow (4) during tipping enables the vehicle to unload the payload even on uneven surfaces without causing the vehicle to tip over.
[033] Referring now to Fig. 2, which is an exemplary embodiment of the present disclosure illustrating a flow chart of a method of stabilizing the vehicle during tipping operation. The order in which the method is described is not intended to be construed as a limitation, and any number of the described steps may be combined in any order to implement the method. Additionally, individual steps may be deleted from the methods without departing from the scope of the subject matter described herein. Furthermore, the method can be implemented in any suitable hardware, software, firmware, or combination thereof.
[034] At Block 201, upon operating the load body to unload the payload, the load body may tip. Upon tipping the controller (5) may receive the tipping angle of the load body from the angle sensor (1). The controller (5) may be configured to continuously receive the tipping angle throughout the tipping operation from the angle sensor (1). Further, the controller (5) may be configured to simultaneously receive pressure in the lift axle suspension bellow (4), from the pressure sensor (2) during the tipping operation. Upon receiving the tipping angle from the angle sensor (1), at Block 202, the controller (5) may be configured to determine pressure which is to be present in the lift axle suspension bellow (4) for the received tipping angle of the load body. The controller (5) determines the pressure which is to be present in the lift axle suspension bellow (4) to stabilize the vehicle during tipping operation.
[035] Upon determining pressure that is to be present, at Block 203, the controller (5) may regulate pressure in the lift axle suspension bellow (4) based on the determined pressure. The regulation of pressure in the lift axle suspension bellow (4) relative to the tipping of the load body, facilitates in stabilizing the vehicle during unloading operations or tipping operations. To regulate pressure in the lift axle suspension bellow (4), the controller (5) may operate the valve (3) which may be coupled to the lift axle suspension bellow (4). That is, the controller (5) may operate the valve (3) to regulate pressure in the lift axle suspension bellow (4). In an embodiment, the controller (5) may receive the real-time feedback of pressure in the lift axle suspension bellow (4)

corresponding to the tipping angle of the load body and regulates the pressure in the lift axle suspension bellow (4). The controller (5) may be adapted to selectively operate the valve (3) to decrease pressure in the lift axle suspension bellow (4), based on increase in tipping angle of the load body. That is, the controller (5) may operate the valve (3), such that, the increase in the tipping angle of the load body may be directly proportional to the decrease in pressure in the lift axle suspension bellow (4). That is, load taken up by the lift axle may reduce relative to the reduction in pressure in the lift axle suspension bellow (4) and correspondingly the load being reduced on the lift axle may be taken up by the front axles of the vehicle. Therefore, the center of gravity may shift towards the front axles and such distribution of load between the front and the rear axles stabilizes the vehicle and mitigates instability which may be caused due to majority of loads acting on the rear axles. The increased stability due to the regulation of pressure in the lift axle suspension bellow (4) mitigates tipping over of the vehicle during unloading the payload. Additionally, such stability which may be facilitated due to regulation of pressure in the lift axle suspension bellow
(4) during tipping enables the vehicle to unload the payload even on uneven surfaces without
causing the vehicle to tip over.
[036] For example, in loaded condition of the load body, the lift axle suspension bellow (4) may be pressurized with fluid at 10 bars. Upon tipping of the load body to 5 degrees to unload the payload, the controller (5) may receive the tipping angle of the load body from the angle sensor (1). Upon receiving the tipping angle from the angle sensor (1), the controller (5) may be configured to determine pressure which is to be present in the lift axle suspension bellow (4) for the received tipping angle of the load body by comparing data in the memory unit. The controller
(5) after determining the pressure which is to be present in the lift axle suspension bellow (4) to
stabilize the vehicle during tipping operation, decreases the pressure in the lift axle suspension
bellow (4) from 10 bars to about 8 bars [The numerical values mentioned for explanation of the
working the system are only approximations and it is envisaged that the values higher/lower than
the numerical values assigned to the parameters, dimensions or quantities fall within the scope of
the disclosure, unless there is a statement in the specification specific to the contrary]. Such,
reduction in pressure in the lift axle suspension bellow (4) in response to the unloading of the
payload, may decrease loads on the lift axle and the amount of load decreased on the lift axle may
be taken up by the front axles due to load distribution and shift in center of gravity. Such load

distribution increases stability of the vehicle and mitigates tipping over of the vehicle during unloading the payload.
[037] In an embodiment, the valve (3) may be a solenoid valve. Further, to enable reducing pressure in the lift axle suspension bellow (4), the system (100) may further include a release valve which may be coupled to the lift axle suspension bellow (4). When the solenoid valve may be operated by the controller (5), the release valve may receive an input signal corresponding to the opening of the solenoid valve. In an embodiment, the release valve may be configured to receive a signal corresponding to operation of the valve by the controller, where the release valve may release an amount of pressure in the lift axle suspension bellow based on the signal received. The input signal may be, for example, a pneumatic signal. Based on the input signal, the release valve may enable venting of the fluid in the lift axle suspension bellow (4), thereby causing a reduction in the pressure of the lift axle suspension bellow (4). Since the venting is based on the input signal, which in turn is based on the operation of the solenoid valve by the controller (5), the reduction in the pressure is carried out based on the signal from the controller (5).
[038] In an embodiment, the system (100) and the method enables the vehicle to carry out tipping operations stably and prevents tipping over of the vehicle. Further, the system (100) and method by increasing the stability of vehicle during tipping operation, facilitates tipping of the load body at higher tipping angles without causing the vehicle to tip over. The increased tipping angles lead to increase in productivity and decrease in time required for unloading. Additionally, such system (100) and method enables the vehicle to perform tipping operations on surfaces which are uneven.

Rather, variations to such systems and methods should be considered within the scope of the detailed description.

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.).
