DETAILED DESCRIPTION OF EMBODIMENTS
[014] The following detailed description illustrates embodiments of the present disclosure and ways in which they can be implemented. Although some modes of carrying out the present disclosure have been disclosed, those skilled in the art would recognize that other embodiments for carrying out or practising the present disclosure are also possible.
[015] FIG. 1 is a block diagram that depicts a two-wheeled electric vehicle with enhanced comfort, in accordance with an embodiment of the present disclosure. With reference to FIG. 1, there is shown the block diagram 100 of a two-wheeled electric vehicle 102 that includes a controller 104, a chassis 106, a stability control system 108, a tilt sensor 112, a seat adjustment system 110, and a rider 116.
[016] The controller 104 is configured to control motion of the two-wheeled electric vehicle differently in different levels of road, such as elevated road, slope road, and horizontal road level. Examples of the controller 104 may include but are not limited to, a processor, a co-processor, a microprocessor, a microcontroller, a complex instruction set computing (CISC) processor, an application-specific integrated circuit (ASIC) processor, a reduced instruction set (RISC) processor, a very long instruction word (VLIW) processor, a central processing unit (CPU), a state machine, a data processing unit, and other processors or circuits. Moreover, the controller 104 may refer to one or more individual controllers, processing devices, or a processing unit that is part of the two-wheeled electric vehicle 102.
[017] The controller 104 is operatively coupled to the stability control system 108 mounted on the chassis 106. The controller 104 receives tilt angle signals from the tilt sensor 114 of the stability control system 108. Based on these signals, the controller 104 executes deployment decisions for the set of balance wheels 204 when the detected tilt angle reaches a predefined threshold.
[018] In operation, the controller 104 processes the received tilt angle signals and compares them with predetermined threshold values. Upon detecting a tilt angle exceeding the threshold, the controller 104 automatically generates control signals to deploy the set of balance wheels 204. The controller 104 maintains continuous monitoring of deployment states through position sensors, ensuring proper stabilization support.
[019] The controller 104 manages transition between different stability states of the two-wheeled electric vehicle 102. During normal operation, the controller 104 maintains the set of balance wheels 204 in a retracted position. Upon detecting instability conditions through the tilt sensor 114, the controller 104 initiates the deployment sequence, activating the necessary actuators for balance wheel extension.
[020] In accordance with an embodiment, the two-wheeled electric vehicle 102 further includes a front-mounted passenger carrier system 228 integrated with a front floorboard area of the chassis 106. The front-mounted passenger carrier system 228 enables direct driver visibility of its contents. The front-mounted passenger carrier system 228 comprises mounting points positioned on the front floorboard area for secure integration with the chassis 102. The front-mounted passenger carrier system 228 provides several technical advantages through its integration with the front floorboard area. The front-mounted passenger carrier system 228 maintains the vehicle's center of gravity by centralizing additional load near the vehicle's midpoint. The front-mounted passenger carrier system 228 enables continuous monitoring during transit due to its position within the driver's line of sight. The front-mounted passenger carrier system 228 is specifically engineered to not interfere with vehicle handling or rider foot placement. The front-mounted passenger carrier system 228 includes structural reinforcements in the front floorboard area to ensure stable support without compromising integrity of the chassis 102.
[021] In accordance with an embodiment, the front-mounted passenger carrier system includes a removable pet carrier and mounting points positioned on the front floorboard area to maintain driver visibility of the pet carrier. Moreover, the front-mounted passenger carrier system allows pet owners to transport the pets safely and comfortably within view, enabling the driver to monitor the pet during the ride, which enhances both the driver's peace of mind and the pet's safety. As a result, by mounting the pet carrier on the two-wheeled electric vehicle 102 allows the controller 104 to minimize distractions, as the rider 116 can directly glance down rather than turning around or relying on rearview checks. Additionally, the removable nature of the carrier offers flexibility, letting users easily attach or detach the carrier as needed, making the two-wheeled electric vehicle 102 versatile and accessible for both pet and non-pet transportation scenarios.
[022] In accordance with an embodiment, the controller 104 further includes a manual override option to maintain the set of balance wheels in a fixed position. Moreover, the controller 104 is configured to provide an additional control, enabling them to manually lock the balance wheels in either the deployed or stowed position based on specific riding preferences or conditions. For example, the rider 116 who feel they need consistent stability support, regardless of speed, can choose to keep the balance wheels extended, while those navigating smoother or faster routes can choose to keep them retracted. As a result, the controller 104 is configured to enhance user confidence, as riders are empowered to adjust stability settings to their needs, making the two-wheeled electric vehicle 102 adaptable and accessible to a broader range of riders.
[023] In accordance with an embodiment, the controller 104 is further configured to detect speed of the two-wheeled electric vehicle and enable balance wheel deployment only below a predetermined speed threshold. In an implementation, the controller 104 is configured to ensure that the balance wheels are only engaged when the two-wheeled electric vehicle 102 is operating at lower speeds, such as during slow manoeuvres, stops, or in crowded environments. Therefore, by preventing balance wheel deployment at higher speeds, the controller 104 is configured to avoid unwanted drag and interference with the handling, maintaining a smooth, agile riding experience of the two-wheeled electric vehicle 102. Additionally, the controller 104 is configured to conserve energy by limiting the deployment mechanism's operation to low-speed scenarios, thus enhancing both the safety and efficiency of the two-wheeled electric vehicle 102 in order to enhance the user confidence by automatically adjusting support based on riding speed, providing an intuitive and secure riding experience.
[024] In accordance with an embodiment, the set of balance wheels are configured to retract against the chassis in a stowed position and extend laterally outward in a deployed position. The retraction of the set of balance wheels are used to provide flexibility by allowing the wheels to be tucked away when stability assistance is not required, optimizing the vehicle's manoeuvrability and reducing drag, thereby creating a versatile and rider-friendly commutation.
[025] In accordance with an embodiment, the stability control system 108 further includes status indicators to display current operating state of the set of balance wheels. The stability control system 108 is configured to provide real-time feedback to the rider 116 in order to enhance the safety of the rider by letting the rider 116 know the exact status of the wheels, particularly during transitions, for example, when the wheels are being deployed to aid stability or folded for increased manoeuvrability.
[026] Advantageously, the two-wheeled electric vehicle 102 includes multiple adjustable components in order to provide enhanced comfort and safety for family commuting. The two-wheeled electric vehicle 102 provides adjustable seat height and foldable backrests for both rider and pillion, ensuring optimal ergonomic positioning for different body types. Furthermore, the two-wheeled electric vehicle 102 includes a removable child seat with integrated safety features including belt and airbag, along with a dedicated removable pet seat 228 thereby, making the two-wheeled electric vehicle 102 versatile for various family transportation needs. The incorporation of foldable balance wheels mounted on the chassis provides additional stability support, particularly beneficial for elderly riders and beginners, while the adjustable shock absorber enhances ride comfort across different road conditions. As a result, the two-wheeled electric vehicle 102 is configured to optimize the family commuting experience by addressing the specific needs of different family members while maintaining safety and ease of use.
[027] FIG. 2A is a diagram illustrating an exemplary scenario of the two-wheeler electric vehicle with enhanced comfort, in accordance with an embodiment of the present disclosure. With reference to FIG. 2A, there is shown a diagram 200A depicting the exemplary scenario of the two-wheeled electric vehicle 102 with enhanced comfort. The two-wheeled electric vehicle 102 includes the chassis 106, and a pair of ground engaging members 204 operatively coupled with the chassis 106. In some examples, each of the pair of ground engaging members 204 includes wheels as shown in FIG. 1.

[028] In an exemplary scenario, the chassis 106 serves as a primary structural framework, forming a backbone of the two-wheeler electric vehicle 102 and extending from front to rear. The chassis 106 incorporates mounting points for the adjustable seat system 212 with height adjustment mechanisms 224. The adjustable seat system 212 includes a rider backrest 222 and pillion backrest 224, both being foldable for enhanced comfort. A removable child seat 226 is attached with a safety belt and an airbag that can be mounted on the adjustable seat structure. The ground engaging members 204 are complemented by the foldable balance wheels 206 mounted on the chassis through a folding mechanism, providing additional stability for elderly riders and beginners. The balance wheels 206 are deployed or folded based on the rider's preference and experience level. The pet seat 228 can be attached to the structure of the two-wheeled electric vehicle 102 for family transportation. The front storage compartment 218 houses the required controls and displays vehicle status through the cluster gauge 220. As a result, the two-wheeled electric vehicle 102 is configured to provide maximum comfort and safety for family commuting while maintaining the practical benefits of electric mobility.
[029] FIG. 2B illustrates another exemplary scenario of the two-wheeler electric vehicle, in accordance with an embodiment of the present disclosure. FIG. 2B is described in conjunction with the elements of FIGs. 1 to 2A. With reference to FIG. 2B, there is shown a diagram 200B that depicts another exemplary scenario of the two-wheeled electric vehicle 102.
[030] In another exemplary scenario, the balance wheels 206 are mounted alongside the main ground engaging members 204 through an engineered folding mechanism integrated with the chassis 106. Moreover, the balance wheels 206 can be folded away when not needed. The balance wheels 206 includes a robust mounting bracket, folding joints, and a locking mechanism that ensures secure deployment and retraction. The positioning of the battery pack 208 and the carrier 210 is optimized to maintain the centre of gravity of the two-wheeled electric vehicle 102 even when the balance wheels are deployed. The chassis 106 is used to reinforce the mounting points to support the balance wheel mechanism while ensuring structural integrity. As a result, the balance wheels 206 are used to enhance the family commuting safety while maintaining the overall versatility of the two-wheeled electric vehicle 102.
[031] FIGs. 3A and 3B are diagrams illustrating top views of a portion of the two-wheeled electric vehicle, in accordance with an embodiment of the present disclosure. Specifically, FIG. 3A is a diagram illustrating a top view of rear wheels of the two-wheeled electric vehicle in a stowed position, in accordance with an embodiment of the present disclosure, and FIG. 3B is a diagram illustrating a top view of rear wheels of the two-wheeled electric vehicle in a deployed position, in accordance with an embodiment of the present disclosure.
[032] With reference to FIGs. 3A and 3B, there is shown the ground engaging member 206 that represents a tire assembly that maintains primary contact with the road surface during vehicle operation. The set of balance wheels 204 are operatively coupled to actuators (not shown) mounted on the chassis through pivot joints.
[033] The stability control system 108 includes actuators coupled to the set of balance wheels 204 for automatic deployment and retraction. Such actuators may comprise electric motors with reduction gearing, hydraulic systems, or electromechanical mechanisms controlled by the controller 104. The stability control system 108 further incorporates position sensors integrated within the actuation mechanism for detecting complete deployment and retraction states of the set of balance wheels 204, providing real-time feedback about their positioning.
[034] In a first configuration, shown in FIG. 3A, the set of balance wheels 204 are in a stowed or retracted position, positioned substantially parallel and proximate to the ground engaging member 206. This configuration minimizes the vehicle's overall width during normal operation and reduces aerodynamic drag. Mechanical stops and locking mechanisms (not shown) secure the set of balance wheels 204 in this retracted position, with the position sensors confirming complete retraction.
[035] In a second configuration, shown in FIG. 3B, the set of balance wheels 204 are in a deployed or extended position, where the set of balance wheels 204 extend laterally outward from the ground engaging member 206 at predetermined angles. This configuration establishes a wider stability base for the two-wheeled electric vehicle 102. The deployment mechanism includes dampeners to ensure smooth extension and prevent sudden impacts during deployment. The position sensors verify complete deployment, while emergency release mechanisms (not shown) enable manual deployment in case of system failure.
[036] The transition between configurations is controlled by the controller 104 based on tilt sensor inputs. The actuators enable variable deployment speeds based on the urgency of stabilization requirements. Proximity sensors monitor the clearance between the set of balance wheels 204 and the ground engaging member 206 during transitions to prevent interference.
[037] FIGs. 4A and 4B are diagrams illustrating top views of a seat adjustment system of the two-wheeled electric vehicle, in accordance with an embodiment of the present disclosure. FIG. 4A depicts a top view of a seat base plate 402 having vertical slots 404 for facilitating height adjustment. The seat base plate 402 includes a central locking point 406, which engages with the locking element 408.
[038] FIG. 4B illustrates a side cross-sectional view of the slot-based height adjustment mechanism, showing the locking element 408 that interfaces with the vertical slots 404. The locking element 408 comprises a center shaft 410 with securing elements 412 that, when tightened, engage with the vertical slots 404 to secure the seat base plate 402 at the desired height position.
[039] The slot-based height adjustment mechanism works in conjunction with independently adjustable backrests for both rider and pillion (not shown in figures). While the vertical slots 404 and the locking element 408 enable height adjustment of the seat base plate 402, the independent backrest adjustability ensures customized support for both rider and passenger positions.
[040] In operation, the securing elements 412 are first loosened, allowing the center shaft 410 of the locking element 408 to slide freely within the vertical slots 404. For example, a rider of height 165 cm might position the seat base plate 402 at a lower slot position, while a rider of height 180 cm might utilize an upper slot position for optimal reach to the ground. Once the desired height is achieved, the securing elements 412 are tightened to firmly engage with the vertical slots 404, preventing any unintended movement during vehicle operation.
[041] The vertical slots 404 of the slot-based height adjustment mechanism are precision-engineered with graduated markings (not shown) to enable repeatable height settings. The vertical slots 404 incorporate wear-resistant surfaces to maintain smooth adjustment capability over extended use. The locking element 408 is designed with self-centering features to ensure even pressure distribution when secured, preventing any wobble or play in the seat base plate 402.
[042] The slot-based height adjustment mechanism, comprising the seat base plate 402, the vertical slots 404, and the locking element 408, incorporates built-in safety features while maintaining structural integrity for both rider and pillion loads during repeated adjustments. The locking element 408 includes a fail-safe retention feature that prevents complete disengagement from the vertical slots 404 during height adjustment, ensuring rider safety even when the securing elements 412 are loosened.
