汽车主动转向附加前轮转角控制的研究

随着汽车电子技术的发展,主动前轮转向系统作为一项新技术越来越受到人们的关注。提出了一种前轮转角反馈控制方法,首先,建立了汽车动力学模型和AFS模型,然后设计主动前轮转向附近前轮转角控制框图,利用Matlab/Simulink软件进行前轮转向角和附加前轮转角的仿真,从而实现附加前轮转角控制。结果表明:低速时,改善了车辆的转向灵活性;高速时,通过附加的前轮转角控制,能提高车辆转向的操作稳定性。

Study on Active Steering with Front Steering Angle Control of Automobiles

With the development of electronic technology,active front steering system is receiving more and more attention because of new technology.A feedback control method is proposed to control superposition angle.Firstly,a mathematics model AFS based on epicyclic train and vehicle dynamic model were built.Model of superimposition deflection angle control was designed.A simulation is performed by input of front steering angle and superimposition deflection angle by Matlab/Simulink.Results showed it is more easy an...
