HYDRAULICALLY ASSISTED HYDRAULIC BRAKING SYSTEM

摘要

The invention relates to an electrohydraulically assisted hydraulic braking system including a master cylinder (100) comprising a thrust chamber (105) and receiving brake fluid under pressure from an accumulator (300) in accordance with a control and using a solenoid valve (200) controlled by a computer (400) by means of the signal output by the sensor (410) of the brake pedal (411) and an electric power source (450) powering at least the solenoid valve (200), the computer (400) and the sensor (410). An auxiliary generator (470) is connected under the control (472) of the computer (400) to the circuit (L0, L1, L2, L3) that powers the computer (400), to the sensor (410) and to the solenoid valve (200) in the event of detecting a fault in the main power source (450), in order to enable the emergency actuation of the solenoid valve (200) and the powering of the brake circuit (C1, C2) for a limited number of brake strokes.
