DETAILED DESCRIPTION

[0001] Generally, one or more rear-view mirrors disposed on a two-wheeled vehicle facilitates a driver of the vehicle in navigating the vehicle in different traffic
5 conditions or on highways. Since, the two-wheeled vehicle is an open type vehicle and the rider is not seated in a closed environment as compared to a three or four wheeled vehicle, the parts enabling the rider in a safe trip is more crucial for the two-wheeled vehicles. The one or more rear view mirrors are disposed on a handlebar assembly, facing towards the rider of the vehicle, so that the rear of the
10 rider is visible to the rider. The rider can keep vigilance on the vehicles by using the rear-view mirrors, coming from behind so as to navigate his/her vehicle accordingly, while moving on roads to avoid any accident due to negligence, rash driving, and in any other types of situations.
[0002] The one or more mirrors are rear view mirrors which is adjusted manually
15 in many vehicles including three-wheeled and four wheeled vehicles. The manual adjustment of the one or more rear-view mirrors, before starting the vehicle, is prone to human error. This leads to mis adjustment of the mirror, causing difficulty for the rider while riding the vehicle. Many-a-times, the rider of the vehicle tends to adjust the vehicle while riding the vehicle itself which is very dangerous as the
20 rider has to take his/her one hand off the handle bar assembly to adjust the one or more rear view mirrors. Letting the rider’s hand off the handle bar assembly and the inattentiveness of the rider can disturb the balance of the vehicle and may lead to collision with nearby vehicles or any other objects in proximity.
[0003] In an attempt to address the problem, many manufacturers are providing a
25 switch operated adjustment means to adjust the one or more rear view mirrors. This solution is well suited for the three or four wheeled vehicle, where the rider is seated in a closed environment and it is difficult for the rider to reach to the both of the rear-view mirrors disposed on both front sides of the vehicle, and thus the rider can adjust the mirrors by pressing the switch for adjustment. In this case also, the rider
30 has to let go off his/her hands off a steering assembly of the vehicle. The switch

operated adjustment is also prone to human error as the adjustment is controlled by the rider itself.
[0004] Therefore, there is need to provide an automatic rear view mirror adjustment system which can provide proper positioning of the mirror without requiring the
5 inputs from the rider, thus acting as a safety feature. Thus, there is a need to overcome the above-mentioned problems and other problems of known art.

The automatic rear view mirror adjustment system 200 includes one or more capturing device 202, one or more control unit 204, one or more rear view mirror 206, and a vehicle ignition switch 208. The one or more capturing device 202 captures a picture of a rider of the vehicle 100. The capturing device 202 may include one of the smart
25 device cameras, a high-definition camera, an on-body vehicle camera and the like. The one or more rear view mirror 104a includes one or more than one rear view mirror 104a provided on the handle bar assembly 104 of the two-wheeled vehicle 100 for the rider. The rear-view mirrors 104a facilitate the rider to be able to view the vehicles coming from behind, to navigate the two-wheeled vehicle 100
30 accordingly, while moving on roads to avoid any accident due to negligence, rash driving, and in any other types of situations. The rear-view mirrors 104a are placed

on both the sides of the handlebar assembly so that the rider is aware of the vehicles coming from behind both on the right side as well as the left side of the vehicle 100. The one or more control unit 204 can be vehicle control unit or a dedicated control unit as well. The vehicle ignition switch 208 is provided in a front portion of the
5 vehicle 100, below the handle bar assembly 104, facing towards the rider. The one or more capturing device 202 is disposed on a rear portion of the handle bar assembly104, facing a rider of the vehicle 100.
[00017] The one or more capturing device 202 capture the picture of the rider. Based on the captured picture, the one or more control unit 204 calculates the height
10 of the rider. Based on the calculated height of the rider, the control unit 204 is configured to control the motor unit (not shown) to adjust the one or more rear view mirror to suit the height of the rider, facilitating automatic adjustment of the rear- view mirror 104a for ensuring safety of the rider and ensuring riding comfort. In an embodiment the motor unit is a stepper motor. However, any type of motor can be
15 utilized to move the rear-view mirrors 104a.
[00018] Fig.3 exemplarily illustrates a Flowchart illustrating the steps for an automatic rear view mirror adjustment as per an embodiment of the present invention. The proposed method controls the position of the one or more rear view mirrors 104a automatically whenever the vehicle 100 is in ON condition. To
20 automatically control the position of the rear-view mirrors 104a, the control unit 204 in the vehicle checks the vehicle ignition condition and confirms if an ignition key (not shown) is switched ON or OFF. The control unit 204 further checks whether the rider is in seating position or not and then the control units 204 checks whether the handlebar 104 angle is less than an adjustment angle or not. In the
25 present embodiment, the control unit 204 checks if the handlebar 104 is tilted at one side, if the handlebar 104 is tilted at one side that means the vehicle 100 itself is tilted at that side as well. So, the control unit 204 do not make any adjustment in the rear-view mirror 206 in that condition, as it will lead to wrong adjustment of the rear-view mirrors 206. Thus, the control unit 204 checks if the handle bar 104 tilt
30 angle with respect to a ground level is less than the adjustment angle or not, if not, then the control unit 204 do not make any adjustment to the rear-view mirrors 206.

Therefore, after satisfying all the above three conditions that is the rider is in seating position, the vehicle ignition key is in ON position, and the handlebar angle 104 is less than the adjustment angle, the control unit 204 captures a picture of the rider. The adjustment angle is pre-stored in the control unit 204. Based on the captured
5 picture, the control unit 204 calculates the height of the rider. After calculating the height, the control unit 204 adjusts the one or more rear view mirrors 206 by moving it up or down, based on the rider’s height. The one or more control unit 204 employs the motor unit to move the one or more rear view mirrors 104a up and down. [00019] The present invention provides an automatic mirror adjustment system 200
10 which automatically adjusts the mirror 104a in accordance with the height of the rider of the vehicle 100. This eliminates any error in rear view mirror adjustment due to human error, eliminating any navigating difficulty to the rider while riding the vehicle 100. The present invention removes the necessity of letting the rider’s hand off the handle bar assembly 104 while riding, thus ensuring safety and
15 enhancing riding comfort, while riding the vehicle 100. Many other improvements and modifications may be incorporated herein without deviating from the scope of the invention.
