The front wheel steering system of conventional vehicle fails to keep the vehicle stable at high speeds and prove futile for heavy vehicles like tracks and trailers, especially in tight space. But if the rear wheels too could be steered, manoeuvrability of the vehicle will be enhanced. This results in the evolution Four-wheel steering (4WS). In 4WS, rear wheel are also steered in combination with the front wheels. This system helps in achieving superior cornering stability, improved steering responsiveness and precision, high -speed straight-li ....etc

Abstract:
An automatic jack and wheel change system having at least one inverted jack driven by an electric motor permanently attached to the vehicle. The system may employ a jack disposed between the front and rear wheel on each side of the vehicle, or it may be equipped with a jack at each of the four wheels. The system also features a novel wheel and hub-axle assembly featuring a split axle whose length may be adjusted by operation of an electric motor. The hub has a plurality of arms extending from the hub in a star-shape, each arm having ....etc

ABSTRACT


In day to day life accidental cases of the four wheeler vehicle is increasing. There are many reasons behind such type of deadly incidences. But main cause behind it is the unawareness of the driver or we can say diversion of the drivers mind at the time of the driving because of the use of the cell phone.
Whenever driver uses his cell phone at the time of driving he engaged his one hand for the holding of cell phone and also his mind gets diverted. Too overc ....etc

Abstract
This paper develops a trajectory planning algorithm for a
four-wheel-steering (4WS) vehicle based on vehicle
kinematics. The flexibility offered by the steering is
utilized fully in the trajectory planning. A two-part
trajectory planning algorithm consists of the steering
planning and velocity planning. The limits of vehicle
mechanism and drive torque are taken into account.
Simulation results are presented to illustrate the
application of the proposed algorithm.

Four-wheel steering, 4WS, also called rear-wheel steering or all-wheel steering, provides a means to actively steer the rear wheels during turning maneuvers. It should not be confused with four-wheel drive in which all four wheels of a vehicle are powered. It improves handling and help the vehicle make tighter turns.

Production-built cars tend to understeer or, in few instances, oversteer. If a car could automatically compensate for an understeer/oversteer problem, the driver would enjoy nearly ....etc

TO DESIGN & FABRICATE A SIX SLOT GENEVA WHEEL MECHANISM
INTRODUCTION
The Geneva mechanism is a timing device. It is used in many counting instruments and in other applications where an intermittent rotary motion is required. Essentially, the Geneva mechanism consists of a rotating disk with a pin and another rotating disk with slots (usually six) into which the pin slides. The Geneva mechanism was originally invented by a watch maker. The watch maker only put a limited number of slots in one of the rotating disks ....etc
