Abstract

The invention relates to an integrated type electronic hydraulic braking system. The integrated type electronic hydraulic braking system comprises a shell body, a main cylinder (15), a motor (16), a pedal push rod (2), a main cylinder push rod (5), a pedal feeling simulator, and a displacement sensor, wherein the main cylinder (15) is connected with the shell body, the output end of the motor (16) is connected with a plunger of the main cylinder (15) through a main cylinder connector (12), and the pedal push rod (2) is connected with a braking pedal; one end of the main cylinder push rod (5) is connected with the pedal push rod (2), the main cylinder push rod (5) slides in the axial direction of the shell body along with the pedal push rod (2), and the other end of the main cylinder push rod (5) and the main cylinder connector (12) are oppositely arranged with a reserved gap to form a decoupled structure; and the pedal feeling simulator is arranged outside the shell body, and connected with the pedal push rod (2), and the displacement sensor is arranged in the shell body. Compared with the prior art, the integrated type electronic hydraulic braking system is available for a traditional vacuum servo brake connector, a sensor is not needed to be additionally installed, and the functions of power-assisted brake, active brake, regenerative brake, auxiliary brake and the like can be achieved; and the integrated type electronic hydraulic braking system has the advantages of being highly integrated, simple and reliable in structure, low in cost, high in universality, and the like.

Description

technical field [0001] The invention relates to an automobile braking structure, in particular to an integrated electronic hydraulic braking system and method. Background technique [0002] In order to solve the serious problems brought about by the growth of car ownership, electrification and intelligentization of vehicles are an important direction for the automotive industry to seek breakthroughs. In urban working conditions, the braking of the car is relatively frequent, so the energy consumed accounts for a large part of the total energy consumed by the car. An important difference between electric cars and traditional cars is the introduction of regenerative braking in the braking system, regenerative braking The recovered energy can increase the mileage of the car, make up for the shortcomings of the current battery technology, and achieve the purpose of energy saving and environmental protection; in addition, the power source of the electric car is completely or part...
