INTRODUCTION          A transmission is a machine in a power   transmission system, which provides controlled application of the power. Often the term transmission refers simply to the gearbox that uses gears and gear trains to provide speed and torque conversions from a rotating power source to another device.               The term transmission refers to the whole drivetrain, including clutch, gearbox, prop shaft (for rear-wheel drive), differential, and final drive shafts. In American   English, however, the term refers more specifically to the gearbox alone, and detailed usage differs. Engine transmission system                         The most common use is in motor vehicles, where the transmission adapts the output of the internal combustion engine to the drive wheels. Such engines need to operate at a relatively high rotational speed, which is inappropriate for starting, stopping, and slower travel. The transmission reduces the higher engine speed

  STEERING SYSTEMS INTRODUCTION           Steering  is the collection of components, linkages, etc. which allows              any  Vehicle   ( car , motorcycle , bicycle ) to follow the desired course. An exception is the          case of rail transport  by which rail tracks  combined together with railroad switches  (and        also known as 'points' in British English) provide the steering function. The primary              purpose of the steering system is to allow the driver to guide the vehicle.                                            Four wheel steering is a method developed in  automobile industry for the effective turning of the  vehicle and to increase the maneuverability. In a typical  front wheel steering system the rear wheels do not turn  in the direction of the curve and thus curb on the  efficiency of the steering. In four wheel steering the rear  wheels turn with the front wheels thus increasing the  efficiency of the vehicle

INTRODUCTION                                  This Auto pilot mode Technology is a research project. By implementing this technology in vehicles enables it to self-drive in the highway roads without the control of the   humans. This  technology creates a new revolution in the Automobile and transport field. It helps the user to save    their valuable time which is wasted while driving and it is not necessary for the drivers to be always seated in the driver seat except the places, where the signals and road counters present. Many accidents are occurred due to the carelessness of the drivers. This can be avoided by implementing this Autopilot mode technology. In this technology many advanced equipment’s are going to be used to make a safe journey. This Autopilot mode technology is going to be created by the combination of various departments in Engineering. But among these departments of Engineering four departments are going to play a major role.
