摘　　要：为了使驾驶人在驾驶大型动力模块车组时获得力反馈真实感,提出基于伺服电机扭矩控制的转向盘力觉真实感系统。基于普通车辆的转向系特性,建立转弯时单个转向轮的转向力修正模型,据此利用动力模块车组同一轴线上2个悬挂转角与转向盘转角的数学关系,建立动力模块车组转向盘转向力模型,在此基础上构建伺服电机驱动的转向盘转向力模拟试验平台和虚拟车辆行驶环境。结果表明:数字转向盘的转向力矩曲线与普通车辆转向力矩特性相近,符合中国标准的规定,验证了所提方法的有效性。To obtain the force sensing during operating steering wheel of large powered modular vehicle, a new steering system with force feedback based on torque control of servo motor was proposed. Based on steering characteristics of common vehicles, a modified force model of single steering tire was built for common vehicles during steering, and then the force model of steering wheel of modular vehicles was built by using the relationship between steering angles of steering wheel and two suspending groups in the same axle. Based on the model, a servo motor driving experimental platform was built to simulate the force sensing on steering wheel of modular vehicles, and also a virtual driving circumstance was constructed to support the experiment. The results show that the steering torque curves are similar to that of common vehicles, satisfying the national standard. The proposed method is verified to be effective.
