The present disclosure generally relates to urban mobility, and more particularly, to two-wheeled vehicles. More particularly, the present disclosure relates to a method and system for detecting helmets inside the two-wheeled vehicle trunk.
Helmets are an essential part of urban mobility. Typically, helmets are stored in vehicle trunks, and in some two-wheelers that do not have a trunk, external locking devices are installed on the two-wheeler for locking the helmet thereto. A disadvantageous aspect of such helmet containing methods is that these methods leave the helmets susceptible to theft.
In order to protect helmets from being stolen, various passive helmet detection methods and systems have been developed in the art. Some such conventional schemes include the use of scales, passive RFID tags, electronic locks, and other means that cannot be programmed. As a result, there is no way to accurately identify the helmet. As such, a disadvantageous aspect of the conventional means is that the helmet may be replaced with another one. In one aspect, if the helmet is replaced or stolen, when replacing them, the provider/user must update the scooter control program. Updating the scooter control program is an arduous task that needs time and technical expertise, which is not helpful for the end user of the scooter. Another disadvantageous aspect of the conventional schemes is optimization of battery consumption while maintaining the accuracy of the radio systems in urban environments and high electromagnetic noise.
Therefore, there is a need for a helmet detection method and system that overcomes the aforementioned disadvantageous aspects of the conventional helmet detection schemes and methods.

The present subject matter envisages a helmet detection system and method, wherein the helmet detection scheme is configured as an active circuit system. In one embodiment, the helmet detection system is deployed on a two-wheeled vehicle. In one embodiment, the two-wheeled vehicle is a scooter. In another embodiment, the two-wheeled vehicle is a motorcycle having a discrete trunk assembled on the body of the motorcycle.
The helmet detection system, in accordance with the present subject matter, comprises a first transceiver. The first transceiver is configured in a trunk of the two-wheeled vehicle. In one embodiment, the first transceiver is configured at the base of the trunk of the two-wheeled vehicle. In one embodiment, the trunk has a size big enough to accommodate two helmets, including one for the rider and one for the pillion passenger. The system further comprises at least one second transceiver that is provided on one or more helmets placed inside the trunk of the two-wheeled vehicle. The system further comprises a transmission device coupled to the first transceiver.
The operation of the helmet detection system, in accordance with an embodiment of the present subject matter, is described herein. The transmission device is configured to detect the opening and closing of the trunk. Once the transmission device detects that the trunk has been opened by a user, the transmission device triggers the first transceiver to initiate and send a first detection signal for detecting the presence of one or more helmets within the trunk of the two-wheeled vehicle. The second transceivers on the helmet are configured to receive the first detection signal and respond with a response signal indicating the presence thereof. In one embodiment, the response signal includes a unique identity marker associated with the one or more helmets. Such an identity marker allows the system to detect that the helmet has not been replaced, and that the helmet being detected is the actual helmet that is paired to the first transceiver. As such, the system concludes that there has been no tampering or any suspicious event that has taken place with the helmet. Similarly, the absence of the response signal for a predetermined time period is an indication that the helmets are not present in the trunk, and that the helmets are stolen.
The first transceiver, in accordance with an embodiment of the present subject matter, sends the information associated with the response signal to the transmission device, subsequent to which the transmission device transmits the information to a base controller for further processing. In one embodiment, the base controller is a central application server, wherein such information allows the central application server to detect the presence or absence of the helmets within the two-wheeled vehicle. In one embodiment, the central application server need not take any action when the response signal indicates the presence of the helmet within the trunk. In another embodiment, the central application server can be configured to create an alert for the owner of the two-wheeled vehicle. The alert can include information about the last known location of the helmet and the contact details of a nearest police authority office near the last known location. In one embodiment, the helmet can include a GPS unit that can facilitate tracking of the helmet. The tracking information can assist the police authorities to track down the helmet and catch the thief.
The system 100 further comprises at least one second transceiver Rx1, Rx2 corresponding to at least one helmet 102 provided on the body of the helmet 102.

In one embodiment, the at least one second transceiver Rx1, Rx2 comprises firmware to respond to the first detection signal with a response signal, wherein the response signal includes a unique identity marker corresponding to the helmet 102. In accordance with an embodiment of the present subject matter, the unique identity marker allows the user to identify the helmet correctly to ensure that the helmet has not been replaced with another inferior quality helmet. If the response signal contains incorrect unique identity marker, it means that the trunk doesn't contain equipped helmet and the smart system is processing such response as the absence of the helmet. Such a feature is especially advantageous in applications where a single vehicle is used by multiple users, for example, scooter rental agencies. In another embodiment of the present subject matter, the helmet 102 can also include a GPS unit provided therein for facilitating the tracking of the helmet in case of theft. The tracking information can be used by relevant police authorities to track the helmet and bring the thief to justice before the relevant judiciary courts.

The transmission device 104 is further configured to transmit information associated with the response signal to a base controller 106.
In an alternative embodiment, the base controller is at least one of a user smart device and a central application server. In one embodiment, the base controller 106 is a central application server, wherein such information allows the central application server to detect the presence or absence of the helmets within the two-wheeled vehicle. In one embodiment, the central application server need not take any action when the response signal indicates the presence of the helmet within the trunk 150A. In another embodiment, the central application server can be configured to create an alert for the owner of the two-wheeled vehicle, wherein the alert can include information about last known location of the helmet and the contact details of a nearest police authority office near the last known location. In one embodiment, the helmet can include a GPS unit that can facilitate tracking of the helmet. The tracking information can assist the police authorities to track down the helmet and catch the thief.
The firmware of the first transceiver Tx is implemented on a microcontroller of the first transceiver Tx.

The tracking information can assist the police authorities to track down the helmet and catch the thief.
One exemplary application of the system 100 and method 300 that can be usable in the scooter rental agency is described herein. A scooter rental agency is a service provider wherein a user registers with a central rental agency server via a user smart device to become a registered user of the scooter rental agency. Registered users of the scooter rental agency have access to scooters that are parked at various locations within a city. To avail the facility of using the scooter, the user is required to put up a request for the same via a smart device application provided on the user smart device. Once such a request is made, the central rental agency server identifies an available scooter for the user in the user's vicinity. The details of such a vehicle are then provided to the user.
Once the user identifies the allotted vehicle, the user proceeds to open the trunk of the vehicle to gain access to the helmets. As soon as the user opens the trunk, the transmission device 104 triggers the first transceiver Tx of the vehicle to detect the presence of the helmet within the trunk 150A of the vehicle. If the system 100 detects the presence of the helmet within the trunk 150A, the same information is conveyed by the transmission device 104 to the base controller 106, which in this case is the central rental agency server. The central rental agency server does not take any action in case the helmets are present.
Another action that the central rental agency can be configured to perform is generating an alert to alert the user that the vehicle is being reallotted because of absence of a helmet inside the vehicle. Furthermore, the central rental agency server can be configured to initiate GPS tracking of the helmet, in accordance with one embodiment. More specifically, the tracking of the helmets can be facilitated by the GPS units GPS 1, GPS 2 provided inside the helmet. The tracking information can be shared with the law enforcement authorities.
One aspect of the system 100 and method 300 that is important to consider is that during a course of a trip, a user can open the trunk 150A multiple times. However, the first transceiver Tx is not triggered every time the trunk 150A is opened to check the presence of the helmet within the trunk 150A. In one implementation, the transmission device 104 provided adjacent the trunk 150A stores the status of helmet check in a memory, and when the ride finishes then the helmet check parameter is reset so that the helmet check can be performed the next time the trunk is opened at the start of the next trip. More specifically, the decision, regarding when the ride finishes, is computed by checking if the current location of the scooter matches with the ride destination that the user provided on the central rental agency application on the user smart device.
An advantageous aspect of the system 100 and the method 300, in accordance with the present disclosure, is the active circuit system configuration of the first and second transceivers. If the helmet is stolen or requires replacement, the active circuit system configuration of the system allows the user to re-program the system 100 for accepting a new unique identity marker of the replacement helmet. More specifically, the first transceiver includes a microcontroller(s) containing the firmware that can be re-programmed to accept the new unique identity marker. As such, the efforts associated with completely re-programming the scooter operation algorithm is eliminated, and the user only has to reprogram a small part of the scooter instead of re-programming the entire scooter operation algorithm.
