纯电动后驱汽车横纵向漂移动力学研究
Study on Lateral and Longitudinal Drift Dynamics of Battery Electric Rear-Drive Vehicles
摘要
Abstract
Analyzing the extreme drifting conditions of vehicle tires can greatly improve the horizontal and vertical control capabilities and driving safety of autonomous vehicles.This paper first adopts the UniTire model to describe the friction characteristics in high slip regions,and then optimizes the vehicle drift control algorithm.Next,based on the vehicle stability control principle,the target pressure for the wheel cylinder was calculated to achieve a quick return of the vehicle to steady straight-line driving after drifting.Finally,the rapid prototype verification was carried out on the CANoe's industrial computer platform by integrating DYNA4 and Simulink.The results show that the control algorithm proposed in this paper allows the vehicle to quickly achieve lateral and longitudinal stability during drifting and to promptly return to straight-line driving after drifting,meeting the real-time control requirements.关键词
