摘　　要：驾驶员希望通过转向盘的力矩信息感知汽车的行驶状态。文章主要研究汽车转向盘力特性与转向盘转角、车速、侧向加速度及转向阻力矩的关系,运用多变量模糊控制技术研究了线控转向系统的路感,通过ADAMS提供离线汽车数据,在Matlab/Simulink中对路感多变量模糊控制器进行了仿真,并对其中一种控制结构进行了硬件在环试验,给出了路感多变量模糊控制的一种参数调整方法以及路感数据。表明仿真同硬件在环仿真结果基本一致,验证了路感多变量模糊控制方法可行。The driver wants to apperceive driving status through the torque information of steering wheel.The force characteristic of steering wheel and steering wheel angle, speed and the relationship between lateral acceleration and steering resistance torque is studied. Using multivariable fuzzy control the road feeling of the wire steering system is analyzed. And through ADAMS the off-line automotive data is provided. Multivariable fuzzy controller have been simulated in the Matlab/Simulink, hardware-in-the-loop test of a kind of control structure is carried out. The adjustment method for the parameter of multivariable fuzzy control and the steering feel data is given. It is indicated that simulation is consistent with the results in the hardware loop test. It is verified that the road feel of multivariable fuzzy control is feasible.
