Steering independent electronic differential based traction control system for independent wheel drive neighborhood electric vehicle

Abstract

This paper presents the modeling, analysis and simulation of electronic differential (ED) based traction control (TC) model for a neighborhood electric vehicle (NEV) with distributed drive power train configuration. This system supervises the torque-speed variation of the independently equipped motor to wheel at various cornering maneuvers of the vehicle. The core concept of this paper is to decrease the system complexity and improving efficiency in neighborhood driving environment. Therefore unlike the conventional ED model, the proposed model eliminates the active involvement of steering wheel feedback and velocity feedback to realize the differential action. Along with the ED system, a TC system relying on road-tire interaction is also proposed to regulate the wheel slip during traction and braking conditions. The ED based TC system established necessary vehicle motion stabilization at various turning maneuvers. The performance of the proposed concept is investigated by various model simulations and analysis. The comparative results with the conventional system present the effectiveness and applicability of the proposed model. © JES 2020. on-line: journal.esrgroups.org/jes.
