Abstract:

The most conventional and general steering arrangement is to turn the front wheels using a hand operated steering wheel which is positioned in front of the driver. The four wheel four mode steering system is a modification for the present steering which is used for the improvement of easiness for vehicle handling. The four wheel four mode steering system assists the driver by controlling the steering angle of the vehicle's four wheels as the requirement of the driver, for making the parking and handling at congested areas easier. For meeting the application the rear wheels steer in the opposite direction or in the same direction of the front wheels, allowing reduced turning radius or sliding of vehicle to sideways; also steering each wheel in opposite direction to rotate the vehicle about its position. It is able to transmit the motion that is given on the steering wheel to the rear wheels and is able to control the front wheels as per our requirements, which is the basic idea of our project four wheel four mode. In convertible four wheel steering with four mode operation four steering modes can be changed as needed which assists in parking at heavy traffic conditions, when negotiating areas where short turning radius is needed, when rotation of the vehicle about its position (360 degree rotation) and in off road driving.

Abstract:

Energy demands are rising as a result of the world's fast urbanization, and sustainable power sources are becoming more and more crucial. In this study, a novel method of harnessing renewable energy is investigated through the use of cutting-edge speed bumps. Advanced piezoelectric materials used in these speed bumps enable them to produce electricity from the kinetic energy of moving automobiles. Our study focuses on the design, testing, and application of these intelligent speed bumps in urban and busy regions. In order to minimise interruption and maximise energy generation, it also evaluates the viability of integrating these power-producing speed bumps into current road infrastructure. This comprehensive evaluation covers more ground than just how well the speed bumps work. It also looks at how they affect traffic safety, the reduction of carbon emissions, and the overall objective of promoting sustainability in urban areas. Beyond the traditional scope, it is a deliberate attempt to present a nuanced understanding of their potential. The focus of our investigation shifts to economic feasibility as we go deeper into the nuances of this revolutionary technology.
