摘要
本文分析了汽车车轮制动瞬态动力学,结合精确的15自由度空间刚体动力学模型,定量地分析了车轮抱死松开所获得的加减速度值,并为防抱制动提供了准确的加减速度阈值,同时考虑到防抱制动系统本身装置的特性,提出了最佳又符合实际的制动力矩控制参数,使仿真结果更接近实际。为电子防抱制动系统的研究提供较完整的理论体系和分析方法,并开发了汽车电子防抱制动系统模型(HVOSM—ABS)及模拟程序。该程序具有16种不同的控制方法,适用于各种不同结构制动器的液压制动系统。
This paper analyzes the transient dynamics of wheel braking and the values of acceleration and deceleration during wheel's lock and release based on accurate 3D rigid body dynamics model with 15 degrees of freedom and defines the acceleration and deceleration thresholds for ABS. Taking into account the characteristics of ABS devices, the paper also presents the optimal brake torque control parameters which make the simulation result more practical. Finally, the model of automotive electronic and lock brake system has been set up, and the simulation program developed, which provides 16 kinds of control methods and is suitable for the hydraulic brake systems with different structure.
