Automobiles plays a crucial role in every individual life. The importance for automobiles is growing a lot in past few years. Automobiles consists of several systems, which helps in normal functioning, some of these are Lubricating System, Gear System, Engine, Steering System and etc.., Generally most of the automobiles consists of manual gear shift which is bit difficult to handle and occupies specific space. These problems can be solved by introducing touch screen based gear shift, which can be precise and effective. By introducing this system accessing of automobiles becomes easier and also requirement of effort will be very less.
Chapter: 1 Introduction 1.1 About suspension system: Suspension takes care of shock and diffuses the kinetic energy with the help of shock absorber. Suspension system takes care of the vehicle's handling thus it provides comfort to the rider because suspension system separates the vehicle from speed breakers, vibration and road discontinuity. Suspension system work in two cycles-the compression cycle and the extension cycle. Engineers have made suspension system that can provide both ergonomic comfort and high speed performance. In past telescopic suspension was there in practice for the two-wheeler.
It is important to design a cockpit that can give comfort to the driver. Improper design of the cockpit can make the driver uneasy, feel uncomfortable and can affect the driver’s driving performance. Comfort in the human-machine interface and the mental aspects of the product or service is a primary ergonomic design concern. Comfort is one of the greatest aspects of a design’s effectiveness and is a primary ergonomics design concern. The utility of
In control system design the modeling of a dynamic system is important as it represents the behaviour and characteristics of the system being controlled. In vehicle dynamic studies, the mathematical modeling of vehicle dynamic motion is done based on physical laws that describe the forces and moment acting on the vehicle body and tyres. The vehicle mode with steering system is drawn in Fig. 1. The equations of Vehicle dynamics are as follows: m( ˙vy + vxγ) = (Fx 1 + Fx 2)sinδf + Fy 3 + Fy 4 +(Fy 1 + Fy 2)cosδf (1) Iz γ˙ = (Fy 1cosδf + Fy 2cosδf + Fx 1sinδf + Fx 2sinδf)lf −(Fy 3 + Fy 4)lr + Mc (2) Mc = t w2 (Fx 1cosδf − Fx 2cosδf − Fy 1sinδf + Fy 2sinδf +Fx 3 − Fx 4) (3) The front wheel steer angle used in these equations is δf and is given by δ
In the preferred embodiment of the present invention, the electronic type brake is employed, and the electric current flowing through this brake is adjusted, so that the velocity of the vertical movement of the spindle sleeve (which is defined to be the ratio of the vertical moving distance to the revolutions of the spindle) can be automatically adjusted. For this purpose, an overall supervising controller in the form of a micro-controller is provided to receive sensed data from a spindle revolution sensing section, a revolution deviation (difference) sensing section, a spindle sleeve position sensing section and a manipulation switching section so as to output computed control data to an electronic brake control section, a motor forward/reverse driving section and an operation and alarming display section. Thus during a tapping or drilling operation, the
It is more practical significant that the tire vertical and cornering parameters are affect on vehicle handling and ride comfort. The vertical stiffness and cornering stiffness of tires on vehicle handling characteristics can be obtained by the simulation process. Vehicle dynamics is the study concerned with the motion of vehicles on a road surface. The vehicle which includes the
In this developed system, the various colour strips are marked on roads and vehicles will have a colour detecting sensor located below the bumper on chassis of vehicle which will recognize the colour of colour strips marked on roads and accordingly maintain the vehicles speed in that particular limit. In this way, this system reduces the road accidents and gets driving comfort for the driver because of limited speed. The different areas where the automatic speed control system recommended are • Mostly useful to avoid an accidents on turning area/sharp corners in government area (offices), defence / camp area or Residential area, school zones and villages that are located at the highways and beside the highways. • Sometimes on zigzag roads speed limit takes place. In such case, also this system plays an important role to avoid accidents.
The amount of noise and vibration reaching people are different from one another. The interior noise of vehicle also depends upon the type of vehicle and the occupied space considered. The noise of a vehicle is due primarily to the engine, transmission system and accessories, road excitation, and air buffeting. The noise is produced by complex vibrations of the outer surfaces of the
Introduction: The automotive chassis provides the strength necessary to support the vehicular components and the payload placed upon it. The suspension system contains the springs, the shock absorbers, and other components that allow the vehicle to pass over uneven terrain without an excessive amount of shock reaching the passengers or the cargo. The steering mechanism is an integral portion of the chassis, as it provides the operator with a means of controlling the direction of travel. The tyres grip the road surface to provide good traction that enables the vehicle to accelerate, brake, and make turns without skidding. Working in conjunction with the suspension, the tyres absorb most of the shocks caused by road irregularities.
The main purpose of this kind of braking system to sense the obstacles at rear and actuate the brake for prevention purpose. CHAPTER 1 1. Introduction 1.1 BRAKE 1.1.1 NEED OF BRAKE The vehicle had been started, accelerated and was running on the road, which is now to be stopped. Stopping of the vehicle is as necessary as its starting. Once vehicle is started, it must be stopped somewhere.
