Abstract: A method (400) for controlling the braking action applicable by a brake caliper on a mechanical movement member of a vehicle, said brake caliper being actuatable by an actuator assembly comprising at least one electric motor and an actuator of the brake caliper, the electric motor being operatively connected to the actuator by means of a transmission mechanism, the electric motor being configured to operate the actuator by means of the transmission mechanism. The method (400) comprises the steps of: receiving (401), by an electronic control unit operatively connected to the actuator assembly, an input signal representative of a braking request; determining (402), by the electronic control unit, on the basis of the received input signal, a first reference value of a position of a component in the actuator assembly and a second reference value of a parameter representative of the braking action applicable by the brake caliper by means of the actuator assembly; determining (403), by the electronic control unit, a first feedback value of the position of a component in the actuator assembly; determining (408), by the electronic control unit, a second feedback value of the parameter representative of the braking action applicable by the brake caliper by means of the actuator assembly; generating (411), by the electronic control unit a first intermediate control signal of the actuator assembly on the basis of the comparison between the first feedback value of the position of a component in the actuator assembly and the first reference value of the position of a component in the actuator assembly; and a second intermediate control signal of the actuator assembly on the basis of the comparison of the second feedback value of the parameter representative of the braking action applicable by the brake caliper by means of the actuator assembly and the second reference value of the parameter representative of the braking action applicable by the brake caliper by means of the actuator assembly; generating (412), by the electronic control unit, a control signal of the actuator assembly on the basis of the first intermediate control signal of the actuator assembly and of the second intermediate control signal of the actuator assembly; providing (417) to the electric motor of the actuator assembly, by the electronic control unit, the generated control signal.

Abstract: 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.
