VEHICLE BRAKING SYSTEM

A vehicle braking system comprises a master cylinder (MC) for generating a fluid pressure that causes the actuation of brake devices (F1, F2, F3, F4) associated with the wheels of a vehicle following an intervention on a brake pedal (P). In the delivery line (MC1, MC2) of the master cylinder (MC) there is a pressure transfer device (PT1, PT2, PT3, PT4), which generates a pressure in the hydraulic actuating line (AL) of a respective brake device (F1, F2, F3, F4) following a fluid pressure communicated to a first inlet (24) of the pressure transfer device from the delivery line (MC1, MC2) of the master cylinder (MC) and/or following a fluid pressure supplied to a second inlet (25) of the pressure transfer device from an electrically-operated fluid pressure source (EHAS). A solenoid valve (EV1, EV2) for enabling/disabling the master cylinder (MC) is interposed in the delivery line (MC1, MC2) of the master cylinder (MC). An electronic controller (E) controls the enabling/disabling solenoid valve (EV1, EV2), and the electrically-operated fluid pressure source (EHAS) to create different operating modes of the system. The system does not include any vacuum-operated servo-assisting devices. The master cylinder (MC) is associated with a hydraulic device for adjusting the feeling on the brake pedal (PFP), in which a fluid pressure is generated that opposes the brake pedal (P) actuation. The electronic controller (E) controls the pressure in the device for adjustment of the feeling on the pedal (PFP) by means of a proportional solenoid valve (11) that regulates the communication of the pressure chamber (7) of the device for adjudtment of the feeling on the pedal (PFP) with the discharge and supply reservoir (S).
