摘要

Electric vehicles (EVs) together with batteries, fuel cells, and hybrid vehicles have been developed worldwide as a solution to energy and environmental problems. In the existing controller, the stability of the vehicle is not maintained and also the constant slip ratio is effective only when the vehicle is going straight. In addition, the torque ripple is high due to the vibration and noise which occurs in the motor which results in a lack of efficiency in optimization. Thus, this work proposed an Intellectual Power Management Unit (PMU) controller where it is imposed with the Distribution of Torque (DOT) Algorithm to sustain the stability of the vehicle. Also, the Slip Rate Reckoner (SRR) technique is proposed which provides a constant slip ratio even during cornering which maintains tire traction. To control the torque during the operation Enhanced Torque Assignor (ETA) technique is implemented to reduce the ripple in the torque. Finally, the Stator core (SC) geometry optimization is proposed in the motor by which maximum torque efficiency is achieved. Thus, the overall work enhances the intellectual PMU controller to improve the performance of the electric drive-in vehicles by improving the efficiency of optimization.
