MODELING AND SIMULATION OF FOUR-WHEEL STEERING SYSTEM FOR A PASSENGER CAR
Authors
Abstract
The steering system plays a vital role in a car, allowing
the driver to turn the vehicle effortlessly, and it is the most
important system for handling. In a conventional steering
system, the driver has to put more effort into steering on small
and narrow roads. In this paper, we propose an idea to
implement a steering system for the rear wheels in addition to
the front wheels, resulting in a four-wheel steering system. This
will enable the driver to seamlessly turn the vehicle without any
extra effort. To construct this model, we have considered the
specifications of the Maruti Alto K10 car. The working
principle of our model is based on the Rack and Pinion
mechanism. The model consists of two rectangular-shaped
racks: one is connected to the front wheels, and the other is
connected to the rear wheels. During parking and low-speed
maneuvers (less than 40 km/h), when the front wheels are
steered, the rear wheels turn in the opposite direction,
reducing the turning radius and allowing the car to take sharper
turns. In this study, modeling is done using SolidWorks
software and vehicle behaviour is analyzed using a MATLAB
Simulink model. Simulation results show that the proposed
model reduced the turning radius by 30% and also enhances
vehicle handling performance.
