The following specification particularly describes the invention and the manner in which it is to be performed.
TECHNICAL FIELD
[001] The disclosure herein generally relates to an automobile system, and, more particularly, to a vehicle pedal adjustment unit and method thereof.

BACKGROUND
[002] Pedal is a frequently operating part used by a driver while driving an automobile. Operating convenience of the pedal, and height of the pedal is an important factor for safety of driving the automobile. Also, in order to guarantee adaptation of vehicle to an individual (e.g., driver), and different body dimensions or physical characteristics of one or more drivers. The physical characteristics of the individual who drives the vehicle are not known a priori. In the majority of motor vehicles available on market, set of pedals and dashboard are arranged in fixed positions, steering wheel is generally height-adjustable, and seat is adjustable. Foot length and sitting posture of the drivers with different body sizes are different, and requirements for the height of the pedal can be different for different sitting postures and different lengths, which results in that the pedal with fixed height cannot meet the requirements for the operation convenience of the drivers with different body sizes.
[003] With reference to FIG. 1 is a side view of a typical vehicle pedal unit. A fulcrum 102 is in a fixed position, thereby resulting in height of a pedal 104 is also fixed. Hence, drivers such as physically challenged (e.g., handicaps, 5th to 95th percentile person) who are not feeling comfortable and tend to suffer while operating the pedals. During emergency, inefficient actuation of the pedal might lead to a major accident. The drivers need to adjust the pedal height if he/she is very short or handicap by reaching a service station, which creates the fixed pedal position. And it would be difficult for another person when he/she is driving the vehicle.

[035] At step 702, a request is received at the interactive touch panel 202A of the cluster interactive display unit 202 to adjust a position of the pedal 304 of the vehicle. At step 704, the request is processed by setting a pedal position corresponding to the one or more physical characteristics of user in the interactive touch panel 202A. The one or more physical characteristics of the user corresponds to the length of the foot of the user. The slider in the interactive touch panel 202A of the cluster interactive display unit 202 is dragged to set the pedal position corresponding to the one or more physical characteristics of the user. At step 706, the ultrasonic sensor 216A which is attached to the motor assembly 306 is activated to determine the pedal height based on the one or more physical characteristics of the user. The pedal height corresponds to a distance between the pedal 304 and the bracket 308 attached at the floor of the vehicle. At step 708, the floating fulcrum 302 is moved by the motor assembly 306 in a forward direction, or in a backward direction, thereby the position of the pedal 304 is dynamically calibrated based on the measured pedal height. The floating fulcrum 302 is connected to the motor assembly 306.
[036] The pedal 304 is connected to the yoke 314 by the pin 318. The pin 318 is configured to have a sliding motion inside the bracket 308. The yoke 314 includes the threaded shaft 324 which is engaged to the motor assembly 306. The motor assembly 306 includes the rotor nut 404, whose translation movement is arrested, and rotary movement is increased. The rotor nut 404 is secured tightly with the motor assembly 306. The threaded shaft 324 is rotated at ‘n’ times through the rotor nut 404 and the motor assembly 306 to increase a speed of rotation of the threaded shaft 324. The rotor nut 404 corresponds to the winding 402 of the stator 406 in the motor assembly 306. The motor assembly 306 is energized to rotate the rotor nut 404, which allows the threaded shaft 324 to move in a linearly movement and varies a position of the pedal 304 accordingly.
[037] In an embodiment, the floating fulcrum 302 is moved by the motor assembly 306 towards a first position, thereby calibrating a position of the pedal 304 towards a first user, when (a) a distance or movement of the threaded shaft 324 is maximum, and (b) a distance between the pedal 304 and the bracket 308 attached at the floor of the vehicle is maximum. In an embodiment, the first position of the floating fulcrum 302 is away from the bracket 308 attached at the floor of the vehicle. The foot length of the first user is short. In an embodiment, the floating fulcrum 302 is moved by the motor assembly 306 towards a third position, thereby calibrating a position of the pedal 304 away from a third user, when (a) a distance or movement of the threaded shaft 324 is minimum, and (b) a distance between the pedal 304 and the bracket 308 attached at the floor of the vehicle is minimum. In an embodiment, the third position of the floating fulcrum 302 is closer towards the bracket 308 attached at the floor of the vehicle. The length of the foot of the third user is long.
[038] The embodiments of present disclosure herein addresses unresolved problem of adjusting the height of the pedal according to drivers with different body types or sitting postures of the drivers. The embodiment thus provides the vehicle pedal adjustment unit to dynamically adjust the pedal of the vehicle. The embodiment thus provides a mechanism to vary the fulcrum position of the pedal in order to vary corresponding effective pedal position that can be accessed by the driver. In typical approach as depicted in FIG. 1 (Prior art), the fulcrum is in a fixed position, thereby resulting in height of the pedal is also fixed. However, the proposed design overcome the challenges by providing the floating fulcrum which varies based on the driver’s physical characteristics, thereby position of the pedal is varied. Moreover, the embodiments herein further resolves ergonomic position of the pedal but is not limited to e.g., a brake, a clutch, and an accelerator as per drivers wish i.e., suitable for all kinds of persons/drivers e.g., 5th percentile to 95th percentile and Handicaps. Customized pedal position can be saved by custom settings option based on the passenger's requirement i.e., enables the different persons to drive the vehicle. The ultrasonic sensor is available at affordable price, more reliable and can work efficiently even during night. The proposed approach can be implemented in truck, car, bike, bus, auto etc. In the proposed approach, a clutch pedal are set at height same as height of a brake pedal. The brake pedal is set higher than an accelerator pedal by minimum of 2 inch for adhering safety of the customers and passengers. the proposed approach is compatible for (a) a manual transmission vehicle with the brake, the clutch, and the accelerator, and (b) an automatic transmission vehicle with only the brake, and the accelerator.
