Abstract
Electronic Parking Brake system (EPB, Electronic Parking Brake) is a
kind of electric equipment to improve the driver's manipulation
convenience and parking safety.EPB is also the development direction
of vehicle parking brake system.
This thesis introduced present application situation,development
trend ,the function and significance of development of electronic
parking brake system. on the basis of analysis of national standard,
the thesis designed the function of electronic parking brake system
and gived a detailed description of the electronic brake system
actuator design.According to the requirement of the gradient parking
brake force was calculated.According to the power motor was selected,
According to the transmission ratio, reducer was selected. According
to the strength, wear resistance and stability the screw nut was
designed.
After analysis, the system achieves the expected design functionand
realizes the research program correctness and feasibility.
Keywords electronic parking brake, motor, reducer, screw and nut

1.1 电子驻车制动系统简介
随着科学技术的不断发展与进步，人们对汽车安全性的要求与日俱增，而
优异的制动性能以及一体化的底盘综合控制技术是现代汽车安全性的一个重要
评价标志。大到传统的拉线式油门、雨刮器等，均被电子油门及能随外界雨量
大小而自我调节的智能雨刮器系统所取代[1]
。传统机械制动系统为确保车辆不
溜车，人们不得不拉起手动制动杆。随着机电技术的发展，电子技术不断渗入
到了汽车的制动系统，出现了汽车电子驻车制动系统（EPB），只需按下EPB按
