Abstract

Hub-motor driven electric vehicles consider the upcoming technology in the vehicle industry. It has several merits such as lightweight, good accelerator responsiveness, flexibility when designing different drivetrains, operated at most operative efficiency points, and increased space-saving compared with the traditional electric vehicle driven by a central motor. The energy demand around the world is increasing dramatically. So, the researchers seek to find alternatives to the non-renewable resources represented by fossil fuels. Electric vehicles are the most suitable vehicle to avail of this type of energy due to their high efficiency and zero fuel consumption and emission. The electric-powered vehicle is distinctive with low noise and vibration which improves the vibration characteristics compared with internal combustion engine vehicles. In this paper, eight degrees of freedom passive quarter car suspension system of an in-wheel drive powered electric vehicle equipped with a battery/ultracapacitor hybrid energy storage system is studied and analyzed. The system was simulated and tested in both time and frequency domains via the MATLAB/Simulink environment.

Highlights

Big efforts are employed to solve the problem of diminishing non-renewable resources and save the world from harmful emissions emitted from the internal combustion engine vehicles
The in-wheel motor electric vehicle is an electric vehicle in which the motor is installed on the hub of each wheel
The results showed that the enhancement was done by the active suspension system for the converted vehicle in both ride comfort and handling performance which can be considered as an alternative to the real electric vehicle suspension system [5]

Summary

Introduction

Big efforts are employed to solve the problem of diminishing non-renewable resources and save the world from harmful emissions emitted from the internal combustion engine vehicles. Electric vehicle (EV) is one of the most promising technologies in the last decade. It offers a great solution for the oil shortage and global warming problem [1]. The vehicle vibration responses are determined by its suspension system performance to isolate the vehicle from the vibration produced from the road and powertrain. The in-wheel motor electric vehicle is an electric vehicle in which the motor is installed on the hub of each wheel.
