In this paper, output power distribution algorithm is proposed for the front- and rear-motors through system of four-wheel-drive (4WD) electric vehicles. Through system, optimal control obtained by applying a rate that increases battery range improving efficiency. Optimization according to vehicle driving conditions reduces unnecessary power- loss improves its energy efficiency high-efficiency ...

The existing energy management strategies for four-wheel-drive electric vehicles only take into account the vehicle consumption under static adhesion constraints. However, front and rear axle loads transfer dynamic conditions lead to variations of characteristics, which results in changes consumptions. In this paper, a multi-objective optimal torque distribution strategy is proposed, taking loa...

Design of reliable and robust controller for electric vehicle in urban and sub urban areas is very much challenging task due to time varying load torque requirement at the wheel of the vehicle. In this paper indirect field oriented vector control of induction motor, PI speed control with anti-windup scheme and hysteresis current control scheme have been proposed for three phase induction motor ...

In this paper, we will study a four-wheel drive electric vehicle (4WDEV)with two control strategies: conventional direct torque CDTC and DTC based on fuzzy logic (DTFC). Our overall idea in work is to show that the 4WDEV equipped with four induction motors providing of driving wheels controlled by ensures good stability different topologies road, bends slopes. increases range vehicle. Numerical...

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...

This research focuses on four-wheel-drive electric vehicles. On the basis of hierarchical coordinated control strategy, system driving force distribution regulation and differential braking was designed to increase vehicles steering stability under special road working conditions. A seven-degree-of-freedom model an vehicle established in MATLAB/Simulink, then a coordination Electronic program d...

For high-power electric vehicles (EVs), the drive propulsion based on induction motors is emerging as economical alternative. Compared to conventional motors, open-end winding motor (OEWIM) requires only half dc-bus voltage for given torque. The EV power train dual two-level voltage-source inverter (VSI)-fed OEWIM with isolated dc sources used in this research. uniform state-of-charge (SoC) dis...

An integrated fault-diagnosis algorithm for a motor sensor of in-wheel independent drive electric vehicles is presented. This paper proposes a method that integrates the high- and low-level fault diagnoses to improve the robustness and performance of the system. For the high-level fault diagnosis of vehicle dynamics, a planar two-track non-linear model is first selected, and the longitudinal an...
