Multi-layer Torque Distribution Strategy for Dual Traction Electric Vehicle
摘要
In this paper, a torque distribution strategy is proposed to improve vehicle performance especially in non-uniform driving condition. A set of rules are designed to re-orient the generated torque to the wheels that is susceptible of producing more propulsion torque. In non-uniform driving conditions, the rear or front vehicle differentials gets locked and delivers 95% of the generated torque that is on a ground surface with more friction coefficient in order to develop more propulsion force. The remaining 5% are transferred to the other wheels just to ensure its inertia. The vehicle in this study is driven using two permanent magnet synchronous motors, which are connected to front and rear vehicle wheels. The obtained simulation results are satisfactory and demonstrate the effectiveness of the proposed rule-based torque vectoring strategy.
