汽车线控转向系统稳定性控制策略研究
Research on the stability control strategy of vehicle steer-by-wire system
摘要
Abstract
With the vehicle steer-by-wire system as the research object,this paper builds a sliding mode observer for real-time estimation of the vehicle sideslip angle for active steering controller design.With the vehicle linear two-degree-of-freedom model being the reference model,an active steering sliding-mode controller based on perturbation compensation is designed,where the controller decides the additional front-wheel steering angle,allowing the vehicle response to follow the ideal yaw velocity and sideslip angle and improve the lateral stability of the vehicle.Finally,the effectiveness of the active steering control strategy is verified by the joint simulation platform of Carsim and Simulink under the working conditions of double lane change with low road adhesion coefficients with and without lateral winds.关键词
