In this paper, an intelligent electric power steering system is proposed to replace a traditional hydraulic power steering system and implemented in a real light hybrid electric vehicle. An intelligent fuzzy control algorithm is applied to yield basic assist logic, return compensation logic, damping compensation logic, and inertia compensation logic in an assist steering system. According to st...

In the last years we have witnessed a growing interest, by the academic community and the automotive industry, in the multi-motor electric vehicles. The electrical nature of the propulsion is going to stress even more an increasing insertion of electronic devices in the vehicles. Furthermore, carmakers are performing research and already presented some vehicles based on the concept of X-By-Wire...

Motor patterns displayed during active electrosensory acquisition of information seem to be an essential part of a sensory strategy by which weakly electric fish actively generate and shape sensory flow. These active sensing strategies are expected to adaptively optimize ongoing behavior with respect to either motor efficiency or sensory information gained. The tight link between the motor doma...

Control action is performed by pulse width modulated (PWM) signals generated in dSpace board using Simulin...

This paper deals with sensor fault detection within a reconfigurable direct torque control of an induction motor-based electric vehicle. The proposed strategy concerns current, voltage, and speed sensors faults that are detected and followed by post faulttolerant control to allow the vehicle continuous operation. The proposed approach is validated through experiments on an induction motor drive...

The paper considers abnormal operation modes of an electric drive power subsystem with permanent magnet synchronous motor (PMSM), such as breakdown and burnout of IGBT-transistor in the three-phase inverter. The effect of these faults on the spectrum and form of the currents in the windings of the synchronous motor was studied. Heuristic algorithms based on the form features of the winding curr...

The paper present’s a survey of the wheel vehicles drives with electric and hybrid drive system. For electric and hybrid vehicle applications, wheels motor and magnetic circuits cutting motor drives, represented a new attractive solution for their lightness and compactness. The wheels are directly driven by the electric motor, and the gears are not necessary anymore. An alternating solution of ...
