ABSTRACT:
An electrically controlled braking system allows a pedal stroke produced by an operation of a brake pedal to be detected by a stroke sensor and to be input to a controller, which in turn controls a brake pressure generated by a brake pressure generator in accordance with the magnitude of the pedal stroke. A pedal reaction unit is added to the brake pressure generator. The pedal reaction unit comprises an air cylinder connected to the brake pedal, the stroke sensor which detects the pedal stroke, and a pair of solenoid operated open/close valves for feeding the air pressure from an air tank to, or displacing the air pressure from, the air cylinder. The controller causes the air to be fed to or displaced from the air cylinder in accordance with the magnitude of the pedal stroke detected by the stroke sensor, thus producing a pedal reaction having a controlled magnitude.
