Abstract

The present invention is directed to a vehicle braking system having a stroke simulator and a servo device, which includes a pressure generator for generating a hydraulic braking pressure, a wheel brake cylinder operatively mounted on each wheel of the vehicle, a pressure control valve device which is disposed in a passage for communicating the pressure generator with the wheel brake cylinder, to control the hydraulic braking pressure supplied to the wheel brake cylinder, and an electronic controller for controlling at least in response to an amount of operation of the brake pedal. A master cylinder is provided for communicating with the wheel brake cylinder and supplying the hydraulic braking pressure into it in response to operation of the brake pedal, when at least one of the pressure generator, the pressure control valve device and the electronic controller is abnormal. A stroke simulator is connected to the master cylinder, and arranged to allow the brake pedal to advance in response to the amount of operation of the brake pedal. And, a servo device is provided for assisting the master cylinder to operate when at least one of the pressure generator, the pressure control valve …
