Evaluation of Proposed Controller using Prototype Vehicle with Dual Motor System for EV.

Abstract

We propose a new controller for a large EV drive system that combines two motors and planetary gears. In previous work, it was confirmed via the use of a test bench that the proposed controller can drive the system with less shock than the conventional controller. This paper presents the results of vibration evaluation on a proving ground using a prototype vehicle with a conventional controller and the proposed controller. A discussion of the experimental results is also provided. We used the evaluation methods used in trains to assess the experimental results because the prototype vehicle we developed is a fully electric vehicle. As a result of this study, it was confirmed that the proposed controller is more effective for actual vehicles than the conventional controller.
