In order to evaluate the influence of the dynamics parameters of the electric vehicles on the ride comfort, an electric vehicle dynamic model is established to simulate under various operation conditions of the electric vehicles. The electric vehicle dynamic equations and parameters are then solved based on the Simulink model built on Matlab software. The acceleration responses at centre of gravity of the vertical and pitching electric vehicle vibrations are two objective functions. The research results show that the ride comfort of electric vehicles is greatly influenced by their dynamics parameters and strongly reduced in comparison with the traditional vehicles. Therefore, the electric vehicles equipped with in-wheel motors should be optimized or controlled to improve the ride comfort.

“…Particularly, the fuel cells or electric batteries were gradually studied and used on electric vehicles (EV) [3,4]. The design and optimization of the power battery and torque converter of electric motors to increase the dynamic stability of the EV were also considered [5,6]. The influence of the vibration of in-wheel motors on the wheel dynamic forces had been analyzed [4].…”

In order to increase the stability and movement safety of electric vehicles (EV) under various operation conditions, the battery mass distribution on the EV floor and its load dynamics are concerned in this study. An EV dynamic model with the different battery mass distributions on the EV floor is established and investigated. The EV dynamic equations are then solved via the Simulink model built on Matlab software. The acceleration responses at centre of gravity of the EV and wheel dynamics are two objective functions for evaluating the EV movement safety. The research results show that the optimal position of the battery mass distribution on the EV floor and the ratio between the battery mass and the EV body mass should be reached with from 1.2 to 1.4 m and ≤ 0.6, and the EV's velocity should be from 20 to 35 m/s, therefore, the EV movement safety is remarkably improved.

“…Abdussalam Ali A. O. and Başar Özkan analyzed the effect of in-wheel electric motors mass on the performance of passive and active suspension systems [4]. A modified GPSO-LQG controller is proposed by Fangwu Ma et al for one-quarter EV suspension with the purpose of optimizing suspension performance for entire speed ranges [5]. Liu M. et al proposed the ride comfort optimization of In-Wheel-Motor EV with In-Wheel vibration absorbers using two control methods such as the linear quadratic regulator (LQR) algorithm for suspension damper and the fuzzy PID method for in-wheel damper [6].…”

This paper presents the effect of in-wheel motor (IWM) suspension system on electric vehicle (EV) ride comfort. To analyze the impact on the vehicle ride comfort caused by IWM suspension system, a dynamic model of quarter vehicle is established with the combination of IWM and road surface roughness excitations. The weighted root-mean-square (r.m.s.) acceleration of the vertical vehicle body () according to the international standard ISO 2631-1 (1997) is selected as an objective function to analyze the effect of IWM suspension system when the road surface and IWM mass conditions change. The study results indicate that the effect of IWM suspension system on the EV ride quality is significant and the value of reduces by 8.6 % in comparison to without IWM suspension system. The IWM suspension system has significantly improved the EV ride quality when the road surface and IWM mass conditions change.
