Control method of double-loop electronic hydraulic braking system comprising two channels

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.
