2. ABSTRACT (IN APPX. 200 WORDS):
Now a day’s most of the vehicles use the two wheel steering mechanism as
their main handling system. But the efficiency of the two wheel steering vehicle is
proven to be low compared to the four wheel steering vehicles. Four wheel
steering system can be employed in some vehicles to improve steering response,
increase vehicle stability while moving at certain speed, or to decrease turning
radius at low speed.
Four-wheel steering is a technologically, tremendous effort on the part of
automotive design engineers to provide near-neutral steering. In situations like
low speed cornering, vehicle parking and driving in city conditions with heavy
traffic in tight spaces, high speed lane changing would be very difficult due to
vehicle’s larger wheelbase and track width which brings high inertia and traction
into consideration. Hence there is a requirement of a mechanism which result in
less turning radius and it can be achieved by implementing four wheel steering
mechanism instead of regular two wheel steering.
Four-Wheel Steering System is not a new technology but has it not gained
popularity over Two-Wheel Steering System even though experiments have
proved that it has excellent maneuverability, high stability and it is a solution to
over steer/under steer. If Four-Wheel Steering is a better replacement for age old
3. WHAT ARE THE EXISTING SYSTEM/S IN THAT PARTICULAR DOMAIN THAT YOU HAVE
SURVEYED (IN 500 WORDS):
CONVENTIONAL STEERING SYSTEM
Usually during the steering of the vehicle, only the front wheels are steered
towards right or left according to the requirement and the rear wheels are
followers of the front wheels in this system. Generally it required conventional
rack & pinion gear system for turning of both front wheels.
4. HOW IS YOUR PROJECT DIFFERENT FROM THE EXISTING SYSTEM (IN 500 WORDS):
The purpose of this system is to significantly reduce the turning radius of
the vehicle, thereby improving the performance of the vehicle during
competition. Many factors were taken into account when designing this
system. The foremost criteria of the design were the reduction of the turning
There are some points to describe my project different from existing
1. Superior cornering stability.
2. Improved steering responsiveness and precision.
3. High speed straight line stability.
4. Notable improvement in rapid lane changing maneuvers.
5. Relative wheel angles and their control.
6. Smaller turning radius and tight space maneuverability at low speed.
5. WHY HAVE YOU CHOSEN THE TOOL/TECHNOLOGY/LANGUAGE FOR DEVELOPING
THIS PROJECT? (IN 500 WORDS):
We chose Auto Cad and Pro E software for designing of project and for force
We are also using various machines like lath, welding, drilling etc. for
assembling or machining purpose as required.
6. WHAT ARE THE FUNCTIONAL & NON FUNCTIONAL REQUIREMENTS OF YOUR
PROJECT? (IN 500 WORDS):
We required a work shop for machining of parts and assemble together to
complete the project, welding shop also required for permanent joining of the
Non Functional Requirements -
Industrial visit to any automobile industries may be required, study of
material searched from sites and guidance of respected guides also required.
