[0177] A brake system B of a second embodiment, which differs from that of the first embodiment only in the structure of the power loss failsafe unit 9, will be described below.

[0178] Specifically, such as Figure 13 As shown, the brake system B of the present embodiment is equipped with a power loss failsafe unit 9A. The same reference numerals as employed in the first embodiment will denote the same components, and detailed description thereof will be omitted here.

[0179] The power loss failsafe unit 9A is equipped with a solenoid valve 91 , a pressure regulator 96 serving as a stroke chamber pressure regulator, a check valve 93 , and pipes 95 , 97 and 98 . The pipe 98 is connected at one end thereof to a portion of the pipe 90 extending between one end of the solenoid valve 91 and the seventh port 11h, and is connected at the other end thereof to one end of the pressure regulator 96 . A pipe 97 is connected at one end thereof to the other end of the pressure regulato...

Abstract

A braking device for a vehicle is provided which includes a power fail-safe mechanism which works to create frictional braking force at a wheel of the vehicle in the event of loss of electric power. The braking device is equipped with an electromagnetic valve which is of a normally closed type. In the event of loss of electric power in the braking system, the electromagnetic valve is closed to block fluid communication between a hydraulic booster and a brake fluid reservoir, so that a stroke chamber in the hydraulic booster is hermetically closed. This enables the pressure in a master cylinder to rise in response to depression of a brake pedal to develop the frictional braking force.

Description

technical field [0001] The present disclosure generally relates to a braking system for a vehicle for controlling braking force applied to, for example, an automobile. Background technique [0002] EP2212170A2 teaches an automotive braking system designed to control the braking force applied to a vehicle. The brake system is equipped with: a pedal simulator for simulating the characteristics of a conventional booster system felt by the operator of the vehicle at the brake pedal; The pressure is boosted to create pressure in the master cylinder, which is applied to friction braking. [0003] Hybrid vehicles are generally equipped with a regenerative braking system for generating regenerative braking force upon initial operation of a brake pedal without generating frictional braking force by hydraulic pressure in wheel cylinders. A hydraulic booster as used in a hybrid vehicle is equipped with a dead stroke mechanism that prevents hydraulic pressure from rising when a brake ...
