Study on Differential Assist Steering System with Double In-Wheel Motors with Intelligent Controller
The purpose of this paper is to present a novel controller of differential assist steering system. Firstly, the integrated controller module in electric vehicle is investigated, in which the front axle is refitted for two in-wheel motors. Secondly, genetic algorithm is used to optimize the control d...
