Research on ideal transmission ratio of steering-by-wire system considering driving style
摘要
Abstract
Current design methods of transmission ratio fail to consider the individualized requirements of drivers with distinct driving styles.To address the issue,this paper proposes a new approach to designing transmission ratio for automotive steer-by-wire systems with consideration of driving styles.First,the ideal transmission ratio is determined by fusing the yaw rate gain and the lateral acceleration gain with certain proportions based on the characteristics of vehicle steering gain.Then,driving styles are classified into three types:conservative,moderate and aggressive.On the basis of the proportionally fused ideal transmission ratio,a fuzzy controller is employed with the steering wheel angle and vehicle speed as inputs to dynamically adjust the weight of the yaw rate gain,thus obtaining the ideal transmission ratio adaptable to different driving styles.Finally,the effectiveness of the ideal transmission ratio for different driving styles is verified through simulation in various working conditions on the Matlab/Simulink-CarSim joint simulation platform.Results show the ideal transmission ratio not only meets the requirements of drivers with different driving styles for vehicles'dynamic response,but also markedly enhances their handling stability and safety.关键词
