using an electric differential (ed) in electric vehicle has many advantages such as flexibility and direct torque control of the wheels during cornering and risky maneuvers. despite its reported successes and advantages, the ed has several problems limits its applicability, for instance, an increment of control loops and an increase of computational effort. in this paper, an electric differenti...

Thanks to the development of electric motors and batteries, the performance of EV is greatly improved in the past few years. The most distinct advantage of an EV is the quick and precise torque response of the electric motors. A further merit of a 4 in-wheel-motor drived electric vehicle (4WD EV) is that, the driving/braking torque of each wheel is independently adjustable due to small but powe...

Abstract: This paper presents an in-wheel vibration absorber for in-wheel-motor electric vehicles (IWM EVs), and a corresponding control strategy to improve vehicle ride comfort. The proposed in-wheel vibration absorber, designed for suppressing the motor vibrations, is composed of a spring, an annular rubber bushing, and a controllable damper. The parameters of the in-wheel spring and rubber b...

In addition to clean transportation and energy savings, electric vehicles can inherently offer better performance in the field of active safety and dynamic stability control, thanks to the superior fast and accurate control characteristics of electric motors. With the novel wheel status parameter TA for electric vehicles proposed by the authors in an earlier publication, a new TA index (TAI)-ba...

Tire forces are at the heart of the dynamic qualities of vehicles. With the advent of electric vehicles the precise and accurate control of the traction and braking forces at the individual wheel becomes a possibility and a reality outside test labs and virtual proving grounds. Benefits of individual wheel torque control, or torque-vectoring, in terms of vehicle dynamics behavior have been well...

In this paper, a robust wheel slip control system based on a sliding mode controller is proposed for improving traction-ability and reducing energy consumption during sudden acceleration for a personal electric vehicle. Sliding mode control techniques have been employed widely in the development of a robust wheel slip controller of conventional internal combustion engine vehicles due to their a...

The precise position control, of multi-motor electric vehicles (EVs) by generating the asymmetric pulse generation is presented. The energy saving algorithm is implemented in the power drain control of EV system to improve the electrical safety and slip control of electric vehicle. The acceleration and Deceleration of the electric vehicle for wheel slip control were analyzed using the parameter...

An in-wheel motor electric vehicle has high unsprung mass because of its in-wheel motor, which decreases vehicle ride comfort and vehicle safety. This paper presents a controllable suspension employing an optimal design hybrid damping control strategy based on ideal skyhook and groundhook as a reference. A sliding mode controller is designed to make the plant track the ideal reference model. Th...
