Title:
HYDRAULIC REGULATION UNIT FOR BRAKING SYSTEM IN AUTOMOBILE, BRAKING SYSTEM AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2021/208594
Kind Code:
A1
Abstract:
A hydraulic regulation unit for a braking system of an automobile, comprising a first liquid storage device (29), a second liquid storage device (2), a first fuel return pipeline (110) and a second fuel return pipeline (120). The first fuel return pipeline (110) is configured to be connected to brake wheel cylinders (151), (152) of the automobile, to convey braking liquid in the brake wheel cylinders (151), (152) of the automobile to the first liquid storage device (29), so as to reduce the pressure of wheels of the automobile. The second fuel return pipeline (120) is configured to be connected to the brake wheel cylinders (151), (152) of the automobile by means of fuel inlet pipelines (130), (140) of the braking system, to convey the braking liquid in the brake wheel cylinders (151), (152) of the automobile to the second liquid storage device (2) by means of the fuel inlet pipelines (130), (140) of the braking system, so as to reduce the pressure of the wheels of the automobile, thereby improving the pressure-reducing efficiency of the braking system. Further provided are a braking system for an automobile, an automobile and a control method.
