HYDRAULIC BRAKING SYSTEM ENABLE TO STEADILY STOP A VEHICLE IN THE MALFUNCTION OF AN AHB DEVICE BECAUSE THE BRAKING PRESSURE IS GENERATED BY USING AN ESC SYSTEM INSTEAD OF THE AHB DEVICE

摘要

PURPOSE: A hydraulic braking system is provided to reinforce the running stability on a dried, rainy, gravel, snowy road etc. by instantaneously and independently controlling driving wheels to maintain the stability when a vehicle is about to slip.;CONSTITUTION: A hydraulic braking system comprises an AHB(Active Hydraulic Booster) device(100) and ESC(Electronic Stability Control) system(200). The AHB device stops a vehicle by generating a first braking pressure because the AHB device controls the hydraulic pressure transmitted to a master cylinder from a accumulator when a brake pedal operates. The ESC system stops a vehicle by generating a second braking pressure because the ESC system controls the hydraulic pressure transmitted from the master cylinder to each cylinder. The ESC system generates the fist braking pressure instead of the AHB device in the malfunction of the AHB device.;COPYRIGHT KIPO 2012
