The invention discloses a control method of a double-loop electronic hydraulic braking system comprising two channels, and belongs to the field of electronic hydraulic braking control. An actuating mechanism of the electronic hydraulic braking system of each channel is a braking control module formed by a double-loop braking main cylinder, an ejector rod, a lever structure of the ejector rod, a motor, a transmission structure of the motor and the like. According to the whole vehicle braking system, the electronic hydraulic braking systems of the two channels are used for controlling oil pressure of braking wheel cylinders of wheel edge brakes acting on the two wheels on the left side and the two wheels on the right side of the vehicle respectively, then the braking torque of the wheels is controlled, and two sets of independent braking systems are formed. The electronic hydraulic brake system of each channel controls a brake master cylinder in a double-loop mode, and double liquid loops of front wheels and rear wheels on the same side of the vehicle are formed. In addition, the control system can simulate an ABS system during emergency braking, it is guaranteed that the vehicle always keeps good direction stability and operability during emergency braking, sideslip and deviation are prevented, and the safety performance of the vehicle during braking is improved.
本发明公开了一种包含两通道的双回路电子液压制动系统的控制方法,属于电子液压制动控制领域,每一个通道的电子液压制动系统的执行机构由双回路制动主缸、顶杆及其杠杆结构、电机及其传动结构等共同组成一个制动操纵模块。整车制动系统由两个通道的电子液压制动系统分别控制作用车辆的左侧两个车轮和右侧两个车轮的轮边制动器制动轮缸油压,进而控制车轮的制动力矩,构成两套独立制动系统。每个通道的电子液压制动系统控制着一个双回路形式的制动主缸,构成车辆同侧前轮和后轮的液路双回路。该套控制系统还可在紧急制动时模拟ABS系统,保证车辆在紧急制动时始终保持良好的方向稳定性和可操作性,防止发生侧滑和跑偏,提高汽车制动时的安全性能。
