The invention discloses an automobile anti-lock control method based on an electronic mechanical braking device, which comprises a vehicle single-wheel model, slip rate calculation, road adhesion coefficient calculation, expected slip rate, an ABS controller and the electronic mechanical braking device, and realizes closed-loop control of braking torque by controlling the wheel slip rate, so that the braking distance can be effectively shortened, and the braking efficiency is improved. And the driving safety of the vehicle is improved. According to the electronic mechanical braking device, a planetary speed reducing mechanism and a ball screw pair serve as a transmission mechanism for motor output torque, finally, a piston pushes a braking block to complete braking, a traditional hydraulic device is abandoned structurally, transmission is more stable, control is more accurate, and the emergency braking efficiency of a vehicle can be improved.

    本发明公开了一种基于电子机械制动装置及汽车防抱死控制方法,包括车辆单轮模型、滑移率计算、路面附着系数计算、期望滑移率、ABS控制器、电子机械制动装置,通过控制车轮滑移率来实现制动力矩的闭环控制,能够有效缩短制动距离,提高车辆行驶的安全性。本发明公开了一种电子机械制动装置,将行星减速机构和滚珠丝杠副作为电机输出力矩的传动机构,最终由活塞推动制动块完成制动,在结构上屏弃了传统的液压装置,使传动更平稳,控制更精确,有利于提升车辆的紧急制动效率。
