四轮独立驱动电动车 ARS 与 DYC 集成控制与试验
Simulation and experiment of integration control of ARS and DYC for electrical vehicle with four-wheel-independent-drive
摘要
Abstract
To improve the stability of four-wheel-independent-drive (4WID ) and four-wheel-independent-steering (4WIS ) electric vehicles,a novel integrated control strategy was proposed to combine active rear-wheel steering (ARS)with direct yaw-moment control (DYC).The advantage of horizontal control margin was used to decrease longitudinal control.To maintain the desired steering characteristics using control system,the variable steering ratio reference model was adopted.ARS controller and nonlinear DYC controller with sliding mode variable structure were adopted to compensate the inadequate control within the linear range of tire and improve the handling performance within the nonlinear range of tire.A real vehicle test was conducted based on double lane-change test.The results show that the integrated controller is superior to both ARS and DYC controllers to improve the handling stability of vehicles and reduce the need of yaw moment.The integrated controller can enhance the vehicle longitudinal stability margin and is effective.关键词
