Basic Study on Traction Control of Electric Vehicle

Abstract

Recent researches of electric vehicle are normally focused on batteries and motors themselves. However electric vehicle can achieve high performance motion control by taking advantage of its excellent controllability. In this paper, we propose “traction control”. First, we clarify the static characteristic of vehicle slip phenomena by introducing “constant slip ratio curve”. Next, we propose “model following control” and “slip ratio control” and show their effectiveness by experiments using a real test vehicle.
