DESC:FIELD OF THE INVENTION:
This invention presently relates to the field of Telematics and Internet of Things (IoT).

Particularly, this invention relates to safety of vehicles and its riders / drivers through a set of pre-defined alerts / telephonic communication triggered by pre-defined emergency or critical events.

BACKGROUND OF THE INVENTION:
Road accidents rank 4th among the leading causes of death in the world. Nearly 1.3Mn people die in roads accidents worldwide every year. India alone contributes 12% of these deaths. Among these, 30% of the road accident deaths in India are due to two-wheeler accidents. Approximately, 120 people die every day in India of two-wheeler accidents alone.

Studies have shown that, in the event of an accident, many lives could be saved if accident information reached emergency services immediately on the occurrence of the accident. The timely and accurate detection and reporting of an accident is of utmost importance to both the state and its citizens.

Around 50% of two-wheeler riders are under 30 years of age and are found doing high speed riding. This comes with its own demerits and leads to accidents on roads. When rider experiences a fall, which is critical, there is usually no way for a passing by traveller to locate his identity along with the contact details. Largely, all cell phones are locked or are not in a condition to be used after a critical fall. Under these circumstances, it's the local police that tries to establish connect with the family of the rider. This is done by getting details from the RTO and this process takes a lot of time.

Also, around 60% two wheelers are sold in rural India. For a villager to commute from one village to another or to the nearest cities, using two-wheeler, they have to take internal roads or use national highways. Internal roads are not frequented much. And highways are always prone to high speed traffic and accidents.

Another teething problem related to two-wheelers theft. On an average 450 vehicles are stolen every day. Share of two-wheeler theft is 80% of overall motor vehicle theft. Value of the stolen Vehicle in 2015 was Rs. 4375Mn

When a two-wheeler is stolen, or moved from a standing place, without actual owner riding it, there exists no technology that could communicate to owner about the event, in real time.

Time is of great essence under both the conditions. The first 2 hours from the time of accident are considered golden hours and timely help can save life of the rider/driver when he/she meets with an accident.

Similarly, vehicle theft can also be prevented if timely information is provided to the stake holder/owner of the vehicle.

Therefore, there is a need for a system and method which uses technology to enable instant communication with the rider/emergency contacts, in real time without any delay.

Technology that is integrated into a phone, which is a device used by a large part of the world’s population, would drastically improve the chances of survival of accident victims.

OBJECTS OF THE INVENTION:
An object of the invention is to provide an accident detection and communication over telephone call and SMS which employs an electronic device installed on two-wheeler/vehicle.

Another object of the invention is to provide an accurate accident detection and communication system which eliminates false positives and false negatives.

Yet another object of the invention is to provide an accident detection and communication system which informs a pre-defined contact/s of an accident victim.

Still another object of the invention is to provide an accident detection and communication system which does not need human intervention.

SUMMARY OF THE INVENTION:
Certain embodiments of the present invention can enable this device with the help of gyroscope sensor to detect the emergency or critical scenario triggered by certain events related to a vehicle or its rider/driver.

DETAILED DESCRIPTION OF THE ACCOMPANYING DRAWINGS:
According to this invention, this is provided an emergency or critical scenario detection and communication system concerning a vehicle. Whenever a vehicle enters into a predefined state it sends out an alarm / communication / notification to either owner / owner’s pre-defined contacts related to the state of the vehicle.

Figure 1 is a functional block diagram of the device hardware system.

The device (10) comprises of a set of sensors (12) configured with the vehicle in order to sense various pre-determined data points pertaining to the vehicle. A controller (14) is configured to process the data received both from sensors (12) and transceivers (18). Controller, (14) after processing the data, takes relevant action. For example, if information is received by the controller (14) from the servers (22) through transceivers (18) for immobilizing the vehicle then controller (14) will activate the switch (16) to immobilize the vehicle. Another example is, after receiving the data from sensors (12), the controller (14) looks for outlier in the data and after screening the outliers it transmits the data to servers (22) through transceivers (18).

In at least an embodiment, Gyroscope data is sensed.

In at least an embodiment, Accelerometer data is sensed.

In at least an embodiment, GNSS (13) data is received.

In at least an embodiment, vehicle’s ignition data is sensed.

In at least an embodiment, a first timer is provided, this first timer starts, and produces a first leaning timed signal, when gyroscope senses leaning angle of the vehicle greater than a pre-defined threshold (e.g. 45%) which is greater than the leaning angle of the vehicle resting on its side stand and this first timer stops after a pre-defined duration of time and produces a second leaning timed signal only if the gyroscope continues to record a leaning angle greater than the pre-defined threshold even after expiration of the pre-defined timed duration of the first timer. This first timer ensures that a confirmed fall is determined only when the pre-defined timer duration is breached.

In at least an embodiment, a second timer is provided, this second timer starts, and produces a first response timed signal, when a moving fall is determined and this second timer stops only when a user interacts with the application / second timer associated with this device. This second timer ensures that notifications / alarms should go out only when the user is unable to respond / react / interact with this device, thereby ensuring a serious fall.

In at least an embodiment, at least a switch (16) is operated by controller to immobilize the vehicle.

In at least an additional embodiment, speed of the vehicle is calculated with the help of GNSS data.

In accordance with yet another embodiment of this invention, there is a location determination mechanism i.e. GNSS (13) configured to determine location of the vehicle. A controller (14) continuously receives location data from GNSS (13) and sends it to servers (22) through transceivers (18) on continuous basis.

In accordance with another embodiment of this invention, there is a logging mechanism (22) configured to at least maintain a log of the geo-position(s) of the vehicle.

In accordance with yet another embodiment of this invention, trigger point definition mechanism is configured to pre-define trigger point based on a combination of sensed data from the sensors and the location data. A comparator checks for breach of the trigger points and in the event that the trigger point is breached, a pre-defined notification (alarm, message, etc.) is sent out to a set of pre-defined contacts. The notification is sent by a notification engine configured to send out notifications.

In at least an embodiment, a fall detection mechanism is deployed to detect if there is a fall. Further to determination of fall, speed is sensed and correlated with the fall parameters in order to determine if it was a stationary fall (non-critical) or a moving fall (critical).

A stationary fall is a function of sensed ignition data, sensed gyroscope data, sensed speed, and first timer.

In at least an embodiment, a stationary fall is determined by the controller when ignition data shows that ignition is off and speed of the vehicle is zero and gyroscope data shows that lean of the vehicle is greater than a pre-determined angle and that the leaning occurs for more than the time duration defined by the first timer.

A moving fall is a function of sensed ignition data, sensed accelerator data, sensed gyroscope data, sensed GNSS data, and / or its combinations.
In at least an embodiment, a moving fall is determined by the controller when ignition is “ON”, and there is a speed in the vehicle and gyroscope data shows that lean of the vehicle is greater than a pre-determined angle for a time duration that is greater than that defined by the first timer, and no response has been received by a user even after expiration of the time defined by the second timer.
In at least an embodiment, a moving fall is determined by the controller when GNSS data shows displacement, over a period of time as defined by the first timer, gyroscope data shows that lean of the vehicle is greater than a pre-determined angle for a time duration that is greater than that defined by the first timer, and no response has been received by a user even after expiration of the time defined by the second timer.

In response to determination of a moving fall, an alert to the rider is sent by the notification engine in order to prompt a response. In the event that there is no response from the rider, the fall is categorised as a high-intensity critical fall and the notification engine is then configured to send out notifications to pre-defined personnel such as paramedics, police, response team, family, friends, or the like that have been pre-configured by the user.

The technology has the ability to report an accident even when the rider has been physically incapacitated by the accident.

This technology has an ecosystem that consists of an electronic device installed on a vehicle (two wheeler), on cloud servers and the mobile phone of the rider.

In at least an embodiment, the controller is configured to provide an alert when an authorised attempt is made to move the vehicle with or without ignition being switched on. A user can choose if he or she wants an alert of vehicle movement with or without ignition being on. Using just gyroscope data and GNSS data, the controller determines that the vehicle has been moved, without ignition, and an alert is provided to the user. In cases, where the user chooses to use ignition data, as well, the controller is configured to use at least gyroscope data and / or GNSS data and ignition data to determine that the vehicle has been moved with ignition.

Figure 2A is an installation example of the hardware on vehicle of the user.

The device (20) is placed securely on the chassis of a vehicle (10) which is to be monitored for various parameters. Specifically, this device is placed in communication with the chassis below an area where a pillion rider rides so that it receives continuous uninterrupted strong GNSS signals. Device is not visible from outside and it is secured using steel tie cables on the chassis of the vehicle so that vehicle vibrations are captured accurately and it not easy to open and remove. Also, the device is placed in such a place so that there is no hindrance in receiving GNSS signal. In at least an embodiment, the device is configured to receive GNSS signal from either of GPS, GLONASS, and BeiDou constellations.

Figure 2B is flow diagram as an installation example of the hardware on vehicle of the user.

External body parts of the vehicle are opened (212). Then, a pre-defined place on the chassis of the vehicle is determined (214). The device, of this system and invention, is secured (216), preferably, with a steel tie cable on the chassis of the vehicle. Harness cable (218) is laid and connected to the device. Power connections (220) are made to the device. Ignition sensing connection (222) is made to the device. The external body parts of the vehicle are assembled with the device in place (224).

Figure 3 is a flow diagram illustrating mapping of the hardware system to mobile phone of user and to our servers to enable the device to respond to potential emergency situations.

Firstly, software application is uploaded on user’s mobile (312) associated with the vehicle. Application is communicably coupled with the device and the vehicle (314, 316, 318 320). Emergency contact details of the user are input in the application (322) along with insurance details (324). User data is automatically updated on a server of this system (326).

Device is now mapped with user’s mobile phone and our servers to respond to emergency situation.

Figure 4 is a flow diagram illustrating calibration of the device.

It is ensured that that the vehicle is stationary and not parked on an incline. In case of two-wheelers, the vehicle should be on the main stand during initialisation (412). The application on the user’s mobile is activated (414, 416) for calibration (418, 420). Calibration information is automatically updated on a server of this system (326). Now, device is ready to capture the lean angle of the vehicle the accurately and same gets transmitted to our servers.

Figure 5 is a functional block diagram of the IoT ecosystem along with hardware and mobile phone of user.

Reference numeral 10 refers to vehicle with device installed in it. Reference numeral 30 refers to a user’s or a rider’s mobile that is communicably coupled with this device. Reference numeral 40 refers to a communication tower that facilitates communication of device with our servers at pre-defined events as per an embodiment of the invention. Reference numeral 50 refers to Global Navigation Satellite which helps in determining the location of the device at pre-defined events as per an embodiment of the invention. Reference numeral 60 refers to a server of this system.

Figure 6 is a flow diagram illustrating an example of a technique for automatically providing a failsafe way of detecting and responding to a potential emergency. In this example, the vehicle is a two-wheeler and emergency situation that is being detected is a vehicle fall when it is in motion.

Sensors associated with this device comprise at least a GPS, at least an accelerometer, and at least a Gyroscope, and at least an ignition sensor. With data from at least a configuration of these sensors, the device is enabled to capture GNSS signal along with vehicle lean angle. The sensor data is passed through a filter and filtered data is collated from the sensors. Lean angle is a function of rotational angle with respect to a vertical. During initialisation, a two-wheeler vehicle is kept in a vertical position and sensors are calibrated to read and reference vertical position data, of the vehicle, for purposes of comparison. GNSS sensor gives coordinates for any position from any of the constellations including GPS constellation, GLONASS constellation, and BeiDou constellation.

A Gyroscope is configured to give acceleration readings and an ignition sensor senses if the vehicle is ON.

A first comparator is configured to compare is senses speed is greater than zero “0”. A second comparator is configured to compare is lean angle is greater than 45 degrees. Fall is computed as a function of speed and lean angle; therefore, a moving fall is determined as speed greater than zero and lean angle greater than 45 while a stationary fall is determined as speed equal to zero and lean angle greater than 45 degrees.

As soon as lean angle is detected to be more than 45 degrees, a first timer is triggered. If lean angle becomes lesser than 45 degrees, within this first timer duration, then again speed measurement and lean angle measurement continues in a loop. If first timer expires and lean angle is still more than 45 degrees, then a ‘fall’ is determined.

In response to a determined fall, an alarm is sounded on the user’s/ rider’s phone and there is a second timer window where rider can acknowledge if he or she is fine. If user acknowledgement is received, then it is minor fall and it does not warrant any action.

However, in case no acknowledgement is received, received in this second timer window, then following action takes place.
a) SMS alert including geo location is sent to emergency contacts of the rider
b) Call is placed to emergency contacts of the rider
c) Call is placed to nearest hospital
d) Emergency contacts and hospital speak to each other
e) Hospital sends medical help to accident location

Figure 7 illustrates a battery saving mechanism (70) used, in this system, with the device of this invention.

The device, of this invention, consumes near to zero power from the vehicle’s battery. When vehicle is stationary (i.e. speed=0), ignition is OFF and there is no displacement in the location of the vehicle. In this mode, the device, of this invention, is configured to shut itself off. As soon as there is a physical motion or vibration in the vehicle, the device is configured to switch itself ON.

A battery saving mechanism (70) is configured to achieve this functionality. In this battery saving mechanism, a mechanical normally open switch (72) is coupled with electronic switches (74) configured in this battery saving mechanism. Preferably, a vibration sensor is used as the mechanical normally open switch so that whenever there is physical motion or vibration associated with the vehicle, this mechanical switch (72) oscillates between its open and closed states. If this switch were used as a standalone switch, then each time there is movement of vibration associated with the vehicle, the device (10), of this invention, would also switch ON and switch OFF; this is undesirable. To overcome this, a latching circuit (76) is configured that stays ON whenever the mechanical switch goes ON at the first instance owing to motion or vibration. This latching circuit (76) keeps the device ON irrespective of the fact that the mechanical switch (72) is oscillating between its ON and OFF state. Once certain pre-defined parameter / state is achieved where the system determines that the device (10) needs to be shut down, then the latching circuit is broken with signals received from the controller and subsequently, the device shut down.

The TECHNICAL ADVANCEMENT of this invention lies in providing a device which accurately determines if the vehicle associated with it has one of the problems associated with it, with no false positives or no false negatives:
a) Stationary fall of the vehicle from its resting position;
b) Moving fall of the vehicle while being driven;
c) Ignition tampering of the vehicle;
d) Moving of the vehicle, without the user, without it being switched on;
e) Moving of the vehicle, without the user, while being switched on;
f) Notifying pre-determined contacts upon determination of a moving serious fall;
g) Notifying the user upon determination of a stationary fall;
h) Notifying the user upon ignition tampering;
i) Notifying the user upon movement of the vehicle without it being switched on;
j) Notifying the user upon movement of the vehicle with its ignition being switched on.

While this detailed description has disclosed certain specific embodiments for illustrative purposes, various modifications will be apparent to those skilled in the art which do not constitute departures from the spirit and scope of the invention as defined in the following claims, and it is to be distinctly understood that the foregoing descriptive matter is to be interpreted merely as illustrative of the invention and not as a limitation.
