A method for controlling wheel slip in a braking system of a vehicle includes receiving, by an input interface module of a slip control module, information representative of the vehicle and information representative of an estimate of the status of the vehicle, outputting, by the input interface module, input wheel slip control information, determining, by a parameter self-loading module, based on information representative of the vehicle and information representative of an estimate of the status of the vehicle, wheel slip control parameters, determining, by a plurality of wheel slip control enabling modules of the slip control module, a plurality of enabling signals of the wheel slip control, and determining, by each closed-loop wheel slip control module of a plurality of closed-loop wheel slip control modules of the slip control module a setpoint value of a control variable to be applied to a respective corner of the vehicle to minimize error between the defined slip setpoint and the estimated wheel slip value.

A method for detecting malfunctions of a motor vehicle electro-actuated brake apparatus may include the steps of providing, in an electronic control unit, a functional control block and a first functional block having a numerical model representative of the electro-actuated brake caliper. The method may also include providing a target signal to the functional control block for generating the control signal to operate the electro-actuated brake caliper. The method may also include providing the target signal to the first functional block for generating a first signal. In the method, the first signal may be compared with a feedback signal for generating an error signal to be sent to the electronic control unit. Further, the method may include performing, by the second functional block, an error validation check to provide information on the operating state of the electro-actuated brake caliper to the electronic control unit.

A method for controlling the braking action applicable by a brake caliper on a mechanical movement member of a vehicle is described. An electronic control unit operatively connected to an actuator assembly receives an input signal representative of a braking request. The unit determines 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 a brake caliper via the actuator assembly. The unit determines at least one feedback value of the position of a component in the actuator assembly. The unit also generates at least one control signal for the actuator assembly based on feedback values and the reference values.

A locking device of an electromechanically-operated brake caliper for a disc brake, comprising a ratchet comprising a rotating element having at least one first cam and one first follower pushed elastically against said rotating element, configured to act in conjunction with said at least one first cam to allow the rotation of the rotating element in a first direction of rotation, and to prevent the rotation of the rotating element in a second direction of rotation, opposite to said first direction of rotation; a selector element sliding between a first selector element position and a second selector element position, said selector element being adapted to operate said first follower so that, in said first selector element position, said selector element keeps said first follower in a disengaged position away from the rotating element in which the application of a parking braking action is prevented, and so that, in said second selector element position, the selector element keeps said first follower in an engaged position in contact with said rotating element in which a parking braking action can be applied; said selector element having a second cam and said first follower having a first follower opening forming a second follower, said second cam being configured to act in conjunction with said second follower to operate said first follower between said engaged position and said disengaged position.
