Abstract: 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.

Abstract: A braking system for vehicles may have a control unit for two brake groups operatively connected to electromechanical actuators for each brake group through a relative piloting device. Each control unit may be powered by a power source and being galvanically isolated from other power sources. Each control unit may be programmed to implement, via a piloting device, a standard braking strategy in case of detection of a standard operation of each brake group and a fault braking strategy, if it detects an electrical fault of one or more of the brake groups.

Abstract: 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.
