【摘要】 利用三自由度车辆模型设计了模型预测控制器,发动机力矩PI控制器和制动力矩模糊控制器。并针对制动单移线转向行驶典型工况进行了仿真验证,结果表明,所设计的车辆稳定性控制器具有良好的控制效果,能够明显的改善车辆操纵稳定性;开发的制动力矩算法能够充分利用各个车轮的制动力,使得在发动机力矩改变和主动制动压力等输入都较小的情况下,获得较好车辆操纵稳定性。更多还原

【Abstract】 Model predictive controller,engine torque PI controller and braking torque fuzzy controller was designed based on the three degrees of freedom vehicle model.According to the simulation of single lane steering and brake typical conditions,the design for the vehicle stability controller has good control effect,can obviously improve the vehicle handling stability;The development of braking torque algorithm can make full use of each wheel braking force,makes the engine torque change and active braking pressure input smaller,obtains good handling stability of vehicles.更多还原
