摘要： A braking system for vehicles (4) comprising
- a pilot pump (8) equipped with a manual actuation means (12), a lever and/or pedal, which is fluidically connected, through a first hydraulic conduit (16), to a sorbing device (20) that simulates the actuation resistance offered by a hydraulically operated braking device (24), wherein along said first hydraulic conduit (16) is arranged a first shut-off valve (28),
- a second hydraulic conduit (32) operatively connected to at least one braking device (24) associated with a wheel of said vehicle, said second hydraulic conduit (32) being connected to the first hydraulic conduit (16) through a second shut-off valve (36),
- the system (4) comprising a processing and control unit (40) operatively connected to the pilot pump (8) and motor means (44) for actuating said at least one braking device (24), the processing and control unit (40) being programmed so as to actuate the braking device (24) via the motor means (44) as a function of the actuation of the pilot pump (8) through the manual actuation means (12), in a "by-wire" operating condition,
- in said "by-wire" operating condition, the first shut-off valve (28) being selectively opened and the second shut-off valve (36) being closed. Advantageously, the processing and control unit (40) is programmed to oversee the operation of the braking system (4) so as to correct the braking action requested by the user via the manual actuation means (12), by actuating the motors means (44) so as to avoid the locking of one or more wheels or the onset of instability of the vehicle during braking, said processing and control unit (40) being programmed to induce on the manual actuation means (12) at least a vibration when it corrects the braking action requested by the user.
