AUTOMATICALLY CONTROLLED BRAKING SYTEM FOR MOTOR VEHICLES AND RELATED METHOD OF ACTUATING AND CONTROLLING SUCH A SYSTEM

A braking system for vehicles (4) comprising one manual actuation element (8) connected to a processing unit, wherein the actuation element (8) is provided with contrasting means (32) to simulate an actuation trend, a first actuator device (36) connected to a first and to a second hydraulic circuit (40,44) of a respective first and second braking device (24',24"), the first actuator device (36) being actuated by the processing unit (28). The hydraulic circuits (40,44) respectively comprise a device for regulating the pressure (48,52) interposed between the first actuator device (36) and the corresponding braking device (24',24"), and connected to said processing unit (28), wherein the processing unit (28) is programmed to actuate the regulating devices (48,52) so as to set or vary the actuation pressures of the braking devices (24',24") regardless of the delivery pressures of the first actuator device (36).
