Another aim of the present disclosure is to develop a tank slapper prediction and prevention system, that prevents the rapid and random movement of a handlebar while moving over pothole or bump.

Another aim of the present disclosure is to develop a tank slapper prediction and prevention system having design flexibility.
Accordingly, the present disclosure relates to the construction and mechanism of a tank slapper prediction and prevention system for vehicles such as two-wheelers, three wheelers and the like. Such vehicles have a handlebar to steer the vehicle. The handlebar along with other related parts of such vehicles may have different configuration to adapt the tank slapper prediction and prevention system. Accordingly, the components of the tank slapper prediction and prevention may have different dimension and different outer look depending on the size and configuration of the vehicle. Specifically, the present disclosure relates to develop a tank slapper prediction and prevention system for two-wheelers.
The term 'tank slapper' may be known by a person skilled in the art, which may be defined as a phenomenon of the rapid and random movement of the handlebar when the handlebar hits an undulation on road. The undulation may be potholes, bumps and other obstacles that makes the road surface uneven. It has been seen that when two-wheelers pass through undulations, a rapid and random motion occurs in the handlebar that jolts the rider. The rapid and random movement of the handlebar may cause of unbalancing the two-wheeler. Accordingly, the tank slapper prediction and prevention system are configured to predict undulations on road and prevent the rapid and random movement of the handlebar, respectively. The provision of the tank slapper prediction and prevention system is to temporarily increase the power or torque which is required to rotate the handlebar so as to prevent the rapid and random movement of handlebar. The handlebar rotation effort will be increased only for the duration when the vehicle is passing through undulation.
It should be understood that above configuration is for the sake of describing the invention properly. There may be other configurations which will be obvious to person skilled in the art in view of the present patent application.

Further embodiments of the present disclosure disclose a tank slapper prediction and prevention system configured for predicting undulations on road and preventing the rapid and random movement of the handlebar to eliminate the risk of unbalancing of two-wheeler. The tank slapper prediction and prevention system are herewith in referred to a system.
Reference will now be made to the tank slapper prediction and prevention system which is explained with the help of figures. The figures are for the purpose of illustration only and should not be construed as limitations on the assembly of the present disclosure. Wherever possible, referral numerals will be used to refer to the same or like parts.
Figure 1 illustrates a two-wheeler (1) vehicle which comprises a handlebar (2). According to an embodiment of the present disclosure, the handlebar (2) of the vehicle is connected to a front wheel assembly of the two-wheeler (1). The front wheel assembly comprises a front wheel (4). A pothole/bump (3) is constructed at some distance from the front wheel (4) of the two-wheeler (1) that defines a situation in which the front wheel (4) of the two-wheeler (1) may pass through the pothole/bump (3), by which a rapid and random movement of the handlebar (2) may occur.
Figures 2a and 2b illustrate a situation in which the front wheel (4) of the two-wheeler
(1) is in the pothole/bump (3) and the handlebar (2) is in tilted position. The system is configured with the two-wheeler to predict undulation as pothole/bump (3) on road and increase power/torque against the rapid and random movement of the handlebar
(2) for resisting the undesired movement of the handlebar (2).
Figures 3 to 8 illustrate the system which comprises an optical sending and receiving unit (5), an Electronic Control Unit (ECU) and a force resistance unit (6). The optical sending and receiving unit (5) is configured to predict the undulation on road which is adapted to be positioned in front of the front wheel (4) of the two-wheeler (1). The

unit (5) to receive predicted signals and the force resistance unit (6) to provide processed signals. The ECU (not shown) is configured to process the predicted signals received from the sensing unit of the optical sending and receiving unit (5) and provide processed signals to the force resistance unit (6). The force resistance unit (6) is adapted at the handlebar of the two-wheeler (1). The force resistance unit (6) is configured to provide resistance based on the processed signals against rapid and random movement of the handlebar (2). The said resistance may be in form of power/torque provided to handlebar (2) for resisting the rapid and random movement thereof.
In an embodiment of the present disclosure, a first way to resist the rotation of handlebar (2) is disclosed. The first way to resist the rotation of handlebar (2) may be by using electromagnetic induction, as shown in figures 3 and 4. The force resistance unit (6) comprises a plurality of coils (7) disposed at the handlebar and a Metal Oxide Semiconductor Field Effect Transistor (MOSFET) (12) coupled with the plurality of coils (7) and a plurality of magnets (8). The plurality of coils (7) may be mounted at middle of the handlebar (2) so that the coils (7) can move with the movement of the handlebar (2). The plurality of magnets (8) are positioned adjacent to the plurality of the coils (7) to create electromagnetic induction (13) therein between. The set of magnets (8) are fixedly mounted on a mounting bracket (9) of the two-wheeler (1), as shown in figures 3 and 4. The plurality of coils (7) are configured to ensure the electromagnetic induction (13) with varying intensity, depending on the location of the coils (7). The movement of the plurality of coils (7) in respect of the set of magnets (8) may be cause for the induction of current in the plurality of coils (7). The ECU is configured for providing excitation current to the coils (7). The MOSFET (12) is configured to switch the excitation current in the coils (7) from OFF to ON state or vice versa. The MOSFET (12) is operatively coupled to the ECU for switching from exited state (ON state) to non-exited state (OFF state) and vice versa. The switching action by the MOSFET (12) will be done based on the input received from the ECU. In excited state (ON state), the resistance will be provided against the rapid and random movement of the handlebar (2), based on the excitation current provided by

the ECU. In non-exited state (OFF state), no resistance will be provided to the handlebar.
The plurality of coils (7) along with the MOSFET (12) may be shorted for generating the electromagnetic force against to the rapid and random movement of the handlebar (2). The force resistance unit (6) with electromagnetic induction (13) can be turned ON and OFF very quickly.
In another embodiment of the present disclosure, a second way to resist the rotation of handlebar (2) is disclosed. The second way to resist the rotation of handlebar (2) may be by using hydraulic resistance, as shown in figures 5, 6 and 7. The force resistance unit (6) comprises a set of plungers (14), a channel (15) filled with liquid, a valve (16) and a servo motor (17). The set of plungers (14) has two ends: first end (14a) and second end (14b). The first end (14a) of the set of plungers (14) is connected to the handlebar (2) so that the plungers (14) can move with the movements of the handlebar (2) whereas the second end (14b) of the set of plungers (14) is facilitated by the channel (15) so that the set of plungers (14) can move in the channel (15). The channel (15) may be fixedly mounted on the vehicle main body. The movement of the plungers (14) corresponds to the movement of the handlebar (2). The valve (16) is disposed in the channel (15). The servo motor (17) may be mounted on the channel (15). The servo motor (17) is coupled to the valve (16). The servo motor (17) is operatively coupled with the ECU to control the position of the valve (16). The servo motor (17) operates the valve (16) based on the processed signals received by the ECU. The valve position defines the amount of power/torque that to be generated to resist the rapid and random movement of the handlebar (2). In operation, when the valve is opened, no power/torque will be generated to resist the rapid and random movement of the handlebar (2) as the liquid can flow freely within the channel (15) as per the position of the plungers (14), as shown in figure 7. When the valve (16) is closed, it restricts the liquid to flow within the channel (15) by which an amount of torque/power generates to prevent the rapid and random movement of the handlebar, as shown in figure 6. When the valve (16) is at partially closed position, the two-

wheeler (1) is at high speed to weight up the handlebar (2). The force resistance system (6) with hydraulic resistance may compact, proven and provide variable turning resistance to the two -wheeler (1) depending upon the speed thereof.
Figure 8 illustrates the optical sending and receiving unit (5) adapted at front wheel of the two-wheeler. The optical sending and receiving unit (5) comprises a sensing unit (19, 20) and an extension (18). The sensing unit (19, 20) is configured to predict the undulations such as potholes, bumps, and other obstacles on road. Preferably, the sensing unit (19, 20) is configured to measure the size of the said undulations. The Electronic Control Unit (ECU) is electronically coupled with the sensing unit (19, 20) to receive predicted signals. The sensing unit (19, 20) comprises an optical output (19) and an optical receiver (20). The optical output (19) may be a sensor which includes a laser beam, and the optical receiver (20) may have a camera. The laser beam may be projected on the road at predefined angle. The laser beam and camera, both are positioned in front of the front wheel (4) of the two-wheeler (1). The camera is configured for scanning/recording/observing the laser beam. If an undulation comes in front of the front wheel (4), the laser beam will be distorted. Subsequently, if the said undulation is a bump (3), the laser beam will be appeared closer to the front wheel whereas if the said undulation is a pothole (3), the laser beam will be appeared away from the front wheel (4). The camera observes the said distortion of the laser beam and generates a measured value based on the said distortion. The measured value may indicate the size and/or depth and/or height of the pothole/bump (3). The measured valve depends upon the distortion of the laser beam. The extension (18) may have a shape of a mounting arm or the like. The extension (18) is adapted to accommodate the laser beam and camera at front of the front wheel (4) of the two-wheeler (1). The extension (18) has a first end (18a) and a second end (18b). The first end (18a) is located in front of the front wheel (4) to adopt the laser beam and camera whereas the second end (18b) of the extension (18) may be coupled to mountings of the two-wheeler (1). The laser beam and camera is positioned below axis of a front wheel (4) axle to prevent collision of the optical sending and receiving unit (5) with the obstacle, in case of a minor frontal collision of the two-wheeler (1).

Accordingly, the tank slapper prediction and prevention system enable the advancement in vehicle safety and even user safety by preventing unbalancing of the two-wheeler. The resistance power/torque generation is based on the condition of road surface. The tank slapper prediction and prevention system contain active variable resistance system. The feedback will be generated as per the variation in speed of the two-wheeler.
