Description:SYSTEM AND METHOD FOR RIDER HELMET DETECTION TECHNICAL FIELD [0001] The present subject matter generally relates to automotive safety. More particularly, but not exclusively to a method and a system for a rider helmet detection for a rider riding a vehicle. BACKGROUND [0002] It may be appreciated that a glaring issue of non-compliance with helmet usage among riders of two-wheeler vehicles, such as motorcycles and scooters is prevalent. Often riders carry their helmets loosely in hand or perched atop their vehicles when not in the immediate presence of traffic authorities. Even when helmets were donned, a critical step of securing the strap is often overlooked, rendering the helmet as a protective gear significantly less effective in an event of an accident. Such widespread disregard for basic safety measures poses a severe risk not only to the riders themselves but also to other road users and pedestrians. [0003] Typically, manual helmet checks are done by authorities to prevent riders from riding the vehicles with the helmets. Traffic police or authorities conduct manual checks to ensure that riders are wearing helmets. Such methods rely on visual inspection and is subject to human error and inconsistencies in enforcement. [0004] Some vehicles are equipped with sensors that detect a presence of the helmet on the rider's head. However, such sensors may not accurately differentiate between a properly worn helmet and one that is simply placed on the head without the strap fastened. [0005] Therefore, there is a need in the art for a method and system for rider helmet detection for a rider riding a vehicle. [0006] Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of described systems with some aspects of the present disclosure,

[00057] Figure 3 exemplarily illustrates a flowchart (300) of method for rider registration in the vehicle (102), in accordance with an embodiment of the present disclosure. The flowchart (300) begins at start and moves to step 302. [00058] At 302, an operation of selecting a setting of an application associated with the vehicle (102) may be executed. Herein, an owner of the vehicle (102) may open the application on the instrument cluster (110) or a mobile device associated with the vehicle (102). [00059] At 304, an operation of verifying login credentials may be executed.

25 30 [00062] At 310, an operation of activating the first transceiver (104A), the second transceiver (106), and the third transceiver (108) may be executed. Herein, the first transceiver (104A), the second transceiver (106), and the third transceiver (108) may be Bluetooth devices. In case the first signal transmitted by the first transceiver (104A) is undetected, then the flowchart (300) moves to the block 314. At 314, a notification associated with a turning on of the first transceiver (104A) positioned at the first region of the head wearable device (104) is rendered. For example, the notification “Please wear your helmet” may be rendered on the display device associated with the vehicle (102). [00063] In case the first signal transmitted by the first transceiver (104A) is detected, then the flowchart (300) moves to the block 316. At 316, a notification requesting the user to sit on the vehicle (102) comfortably while wearing the head wearable device (104) with the locking mechanism such as, a strap locked may be rendered. [00064] At 318, a pairing request may be transmitted to the first transceiver (104A) from the second transceiver (106) and/or the third transceiver (108). Upon receiving the pairing request, the first transceiver (104A) may be paired with the second transceiver (106) and/or the third transceiver (108). Thus, the head wearable device (104) may be paired with the vehicle (102). In case the head wearable device (104) is unsuccessfully paired with the vehicle (102), then the flowchart (300) moves to the block 322. At 322, the first transceiver (104A) may be paired with the second transceiver (106) and/or the third transceiver (108) again. [00065] In case the head wearable device (104) is successfully paired with the vehicle (102), then the flowchart (300) moves to the block 324. At 324, the user may be registered. Herein, the processor may determine the first threshold angle of arrival of the second beacon from the first transceiver (104A) to the second transceiver (106). The processor may determine the second threshold angle of arrival of the second beacon from the first transceiver (104A) to the third transceiver (108). The processor may
15
determine a third threshold angle associated with a triangle
formed by the first transceiver (104A), the second transceiver (106), and the third transceiver (108)based on the determined first threshold angle of arrival and thedetermined second threshold angle of arrival. The processor may determine the first threshold distance of the first transceiver (104A) from the second 5 transceiver (106) and the second threshold distance of the first transceiver (104A) from the third transceiver (108) based on the determined first threshold angle of arrival, the determined second threshold angle of arrival, and the determined third threshold angle. The processor may register the user associated with the head wearable device (104) based on the determined first 10 threshold distance and the determined second threshold distance.
[00066] Figure 4 exemplarily illustrates a triangle (400) formed by the first transceiver (104A), the second transceiver (106), and the third transceiver (108)in accordance with an embodiment of the present disclosure. Thetriangle (400) includes a baseline 402, a first side 404, and a second side 406. 15 A length of the baseline 402 is d1, a length of the first side 404 is d2, and a length of the second side 406 is d3.
[00067]
It may be noted that triangulation is a method of positioning that makes use of trigonometric relationships, namely, the law of sines. By placing the second transceiver (106) and the third transceiver (108) at a fixed, known 20 distance from each other, and letting both measure the direction of the first beacon from the first transceiver (104A) of unknown position, it is possible to calculate that position. The law of sines is in accordance with an equation (1)which is:
??sin??=??sin??= ??sin??
(1)
25
where A, B, and C are the sides of the triangle, and a, ß, and ? are the opposite angles respectively. [00068] With respect to Figure 4, the needed information is the first angle of arrival ?2, the second angle of arrival ?3, to calculate the third angle ?1and the
16
transceiver (108)
. Upon determination of the first angle of arrival ?2 and the second angle of arrival ?3, the third angle ?1 may be determined by subtracting the first angle of arrival ?2 and the second angle of arrival ?3 from 180. Thereafter, the length of the first side 404 and the length of the second side 406 may be determined based on equation (1). Further, a distance “l” of the 5 first transceiver (104A) from the baseline 402 may be determined according to the equation (2):
??=??1sin??2 sin??3sin(??2+??3)

10 15 20 25 [00069] In a scenario, an owner purchases a vehicle equipped with the helmet detection system. The owner registers their Bluetooth-enabled helmet and establishes it as the primary helmet for the vehicle. Registration process may involve pairing the helmet with the vehicle's system via the instrument cluster. The owner adds additional users to the system through the instrument cluster. Each new user must wear a Bluetooth-enabled helmet during the registration process. To register a new user, the owner accesses the settings in the instrument cluster, enters the correct password, and pairs the new user's helmet using Bluetooth triangulation. To start the vehicle, the rider approaches with their registered Bluetooth-enabled key (mobile/key fob). The vehicle detects the key and enters idle mode. The rider puts on the registered helmet, ensuring that the helmet is positioned correctly on their head and the strap is securely fastened. The system uses Bluetooth triangulation to detect the presence and positioning of the rider's helmet. If the system verifies that the rider's helmet is correctly positioned and securely fastened, then the system enables the prime mover (engine) to start. If the helmet is not detected, not positioned correctly, or the strap is not fastened securely, then the system prevents the prime mover from starting. During the ride, the system continuously monitors the status of the rider's helmet using Bluetooth technology. If the rider removes the helmet or unfastens the strap while the vehicle is in motion, the system triggers an alert, such as a continuous beep sound or a visual notification on the instrument cluster. If the system detects unauthorized usage, such as a rider attempting to start the vehicle without a 30
17
5
10 15 20 25 30 registered helmet or with an improperly fastened helmet, the system prevents the engine from starting or may disable the engine if the violation occurs during the ride. The system provides real-time feedback to the rider through audio and visual alerts, reminding them to wear their helmet properly and securely fasten the strap. Thus, the system ensures that the vehicle's engine only operates when the rider wears a registered helmet correctly and securely, thereby enhancing rider safety and compliance with helmet usage regulations. [00070] In another scenario, the owner purchases a vehicle equipped with the system for helmet detection. The owner's Bluetooth-enabled helmet is registered as the primary helmet for the vehicle. Additional users are registered by the owner through the instrument cluster. The vehicle's system utilizes Bluetooth triangulation between two Bluetooth beacons (the first transceiver and the second transceiver) mounted on the vehicle, one at the front and one at the rear. During registration, the system records the distance between the two beacons, set at 2 meters for this example. A new user's helmet is registered by pairing it with the vehicle's system, ensuring the head's position registration. The rider approaches the vehicle with their registered Bluetooth-enabled key. The vehicle detects the key and enters idle mode. The rider puts on their registered helmet, ensuring proper positioning and secure strap fastening. The system calculates the angle of arrival of the Bluetooth beacon signal from the helmet transceiver to the vehicle's front and rear beacons. Let's say the first angle of arrival (from helmet to front beacon that is from the first transceiver to the second transceiver) is 30 degrees and the second angle of arrival (from helmet to rear beacon that is from the first transceiver to the third transceiver) is 150 degrees. The system compares these angles with threshold values (e.g., ±5 degrees of the expected values). If both angles fall within the threshold, the system enables the prime mover. During the ride, the system continuously monitors the helmet's position using Bluetooth signals. If the helmet is removed or the strap is unfastened while the vehicle is in motion, the system triggers an alert and may disable the engine. If unauthorized usage is detected, such as attempting to start the vehicle without a registered helmet, the engine remains disabled. The system

Thus, the system ensures that the vehicle's engine operates only when the rider wears a registered helmet correctly and securely fastens the strap, thus enhancing rider safety and compliance with helmet usage regulations. [00071] The proposed system and method provide real-time monitoring. The system provides real-time monitoring of the rider's helmet status, ensuring that the helmet is worn correctly, and the strap is securely fastened throughout the ride. This continuous monitoring enhances safety by minimizing the risk of helmet-related accidents. Further, by requiring riders to register their Bluetooth-enabled helmets with the vehicle's system, the system provides a robust user authentication mechanism. This helps prevent unauthorized usage of the vehicle and ensures that only registered users can operate the vehicle. [00072] The system uses triangulation method. The use of Bluetooth triangulation enables precise detection of the rider's helmet position and orientation relative to the vehicle's Bluetooth beacons. This triangulation method enhances accuracy in determining whether the helmet is worn correctly and securely fastened. By integrating Bluetooth technology with helmet detection sensors, the system enhances overall safety features in two-wheeled vehicles. It helps mitigate the risks associated with improper helmet usage, reducing the likelihood of head injuries during accidents. The use of Bluetooth technology and existing vehicle instrumentation keeps the implementation costs relatively low compared to other sophisticated safety systems. This makes the system accessible to a broader range of users without compromising on safety standards. [00073] The system supports multiple users, allowing vehicle owners to register additional users through the instrument cluster. This feature enables shared usage of the vehicle while maintaining individual user authentication and helmet compliance. The system automatically triggers alerts, such as audio beeps or visual notifications, if the rider's helmet is not worn correctly or the strap is not securely fastened. These alerts serve as immediate
