Project Summary

Innovations in electric vehicles are undoubtedly crucial for the future of the automotive industry. This project aims to open doors towards the concept of green mobility with features that portray the advantages of battery-operated vehicles over traditional fuel-powered ones. This will change the way that we have thought of cars up till now. Our objective is to design, simulate and manufacture an electric vehicle that steers via a complex wheel-hub assembly that can allow free rotation of individual wheels up to angles of 90 degrees whilst simultaneously ensuring an efficient means of power transmission. Moreover, a series of sensors are attached to the vehicle to assist the driver and detect potential accidental hazards. The objective is to manufacture an eco-friendly electric vehicle that can reduce the problems of pollution, accidents, traffic, parking and give the users an experience of a lifetime by eliminating driving restrictions and immense handling skills required to drive a car. This model is 37.5% more efficient than the previous similar mechanisms because of minimized motors utilization overcoming similar tasks. Some key features of the model include:

• 90-Degree Wheel Rotation
• Parallel Parking
• Swift Lane Changing
• Crab-Walking (Diagonal Movement)
• Minimized Turning Radius
• Electronic Steering System
• Safety Monitoring and Driver’s Assistance
• Display for Driver’s Visualization

Project Objectives

Design and development of a four-wheel steering system with:

• Individual wheel hub design which allows rotation of wheels in 2D (axial and transverse).
• Sensor implementation for safety monitoring and driver assistance.
• Advanced parking system with parallel movement.

Project Implementation Method

The project aims to design and fabricate a steering system to increase the manoeuvrability of an electric vehicle by utilizing the concept of wheel rotation. This design will provide the vehicle with parallel movement, traditional steering, smaller turning radius and a high-speed profile for better handling. Motors will be used for the rotation, and they will be incorporated in a specially designed wheel assembly made of combination of bevel and spur gears. For safety purposes, important measurements and other aspects of driver assistance, the use of electronic sensor(s) is intended.

Method steps include:

• Detailed research and study for efficient car handling and manoeuvrability.
• Design, analysis and simulations of wheel hub and 2D rotation.
• Programming and placements of motors and respective sensor(s).
• Fabrication and manufacturing of Electric Vehicle with four-wheel steering system.
• Testing and evaluation of wheel rotation and desired motions.
• Programmable and convertible to autonomous for future considerations.

Benefits of the Project

The automobile industry is constantly on the lookout for new technology that can enhance both driver experience and vehicle performance. It is obvious that the world population is increasing, causing the need for more personal vehicles to surge along with it. This means that there is a greater risk of accidents, as well as severe problems of traffic and parking. Moreover, an increase in the number of vehicles also means an increase in global pollution, which pushes us to think more about the development of electric vehicles.

Our project aims to provide a solution for the above problems and promote a safer future using some of the latest technologies present today. To assist with parking and changing lanes, our model will be built with 90-degree rotating wheels with a unique wheel design and a carefully crafted steering mechanism that can assist the driver to switch between different modes of operation whenever the need arises. Additionally, this technology will be implemented into an electric vehicle, instead of one that operates on fuel, to combat the problem of pollution. Also, the model will be equipped with extremely responsive electronic sensors that can alert the driver of potential accidents on the road, as well as aid with parking in parallel mode.

The objective is prolonged use in the automobile industry, with the advanced parallel-parking system. The steering mechanism may also be used for swift handling of any vehicle. The applications of this project are not limited just to the automotive industry, as it could be used to numerous other industries including robotics as delivery robots, carrying natural disaster relief packages, all-terrain bots etc. as well as industrial transportation to carry large machines without having to change its orientation.

Target Industries: Automotive, Robotics, Transportation, Warehouse, Delivery, Agriculture, etc.
