摘要
为了提高制动过程的舒适性并消除制动操作时的不适感,考虑到制动踏板感觉是线控制动系统研究的核心内容并直接关系到车辆的驾驶舒适度及行驶安全性,利用踏板行程模拟器来模拟制动踏板感觉,并分析比较传统制动系统和带有踏板行程模拟器的线控制动系统.利用AMESim软件建立踏板行程模拟器模型,利用MATLAB/Simulink软件设计踏板行程模拟器的单神经元自适应智能PID控制策略.设置传统车辆制动系统台架试验基本参数并进行仿真验证,最终得出该线控制动系统中的踏板行程模拟器和控制策略均能达到传统制动系统的性能要求,并有效地改善了制动过程中的舒适度.
To improve the braking comfort, the brake pedal feel was simulated by pedal stroke simulator with the consideration of brake pedal feel as core part of brake-by-wire system and direct relationship to driving comfort and safe travel performance of vehicle. The brake-by-wire system with pedal stroke simulator was analyzed and compared with the traditional braking system. The pedal stroke simulator model was established by AMESim software, and a single neuron adaptive intelligent PID control strategy of pe- dal stroke simulator was designed by MATLAB/Simulink software. The basic parameters of bench test of traditional vehicle braking system was set to be simulated for validation. The simulation results show that the pedal stroke simulator and the control strategy can meet the performance requirements of traditional braking system with improved braking comfort.
