The method 300 further includes at a step 308, communicating, by the control unit 108, the signal to the brake system 20 of the vehicle 10 for applying brake for reducing speed of the vehicle 10 or to stop the vehicle 10 based on the inputs from the first image capturing device 102, the second image capturing device 104, and the sensor 106.
[042] In an embodiment, the method 300 at the step 308 further includes, communicating the signal to the brake system 20 of the vehicle 10 for applying brake for reducing speed of the vehicle 10 with the pre-defined gradient or stopping the vehicle 10 completely, when there is at least one of the one or more object(s) in front of the vehicle 10 and the rotation of the rider’s head is greater than the pre-defined threshold value which signifies inattentiveness of the rider towards the front of the vehicle 10.
[043] In an embodiment, the method 300 includes a step of receiving information, by the control unit 108, about a present speed of the vehicle 10. In an embodiment, the method 300 includes a step of computing, by the control unit 108, a distance of the one or more object(s) from the vehicle 10 and time required to reach by the vehicle 10 based on the present speed of the vehicle 10.
