A Study of Brake Pressure Increase Velocity in Anti-Lock Brake System Control

摘要: 研究制动压力增长速率对制动防抱死系统(ABS)控制效果的影响. 采用PWM控制方法,在制动压力增长过程中,通过改变占空比达到改变制动压力增长速率的目的. 提出了偏离度的概念.研究表明,使偏离度最小化的占空比能使制动压力增长速率达到最优,该方法显著提高了ABS控制效果.

Abstract: Velocity of pressure increase impacting on the anti-lock brake system(ABS) control is studied. In order to change the velocity of pressure increase, PWM control is adopted and duty cycle changed. Advanced concept of dispersion degree, duty cycle that minimizes the dispersion can optimize the velocity of pressure increase and improve the ABS control.
