Automatic control braking system for vehicles

A braking system for vehicles, comprising:

• a master cylinder,
• at least one braking device,
• the master cylinder being provided with a first and a second output circuit, containing the same brake fluid, wherein the first output circuit is intercepted by a first control valve fluidically connected to a braking simulator and to said at least one braking device so as to alternately connect the first output circuit to the braking simulator or to said at least one braking device for its actuation, and the second output circuit is fluidically connected to said at least one braking device for its actuation,
• an automatic hydraulic actuation unit operatively connected to the master cylinder by a hydraulic actuation circuit containing an actuation fluid distinct from said brake fluid and fluidically separated from it,
• at least one processing and control unit of the system that supervises the operation of the braking system,
• wherein
• the master cylinder comprises a pump body that houses a first and a second float fluidically connected respectively to the first and second output circuit to pressurise said brake fluid,
• wherein the first float is operatively connected to a manual actuation device, and the second float is operatively connected to the unit automatic hydraulic actuation unit to be actuated by the hydraulic actuation circuit,
• wherein the first float is provided with a first pumping head slidingly housed inside a first output volume of the pump body, the second float is provided with a second pumping head slidingly housed inside a second output volume of the pump body, said first and second output volume being fluidically separated from each other.
