Abstract: Various braking devices, systems, and methods are disclosed. In some embodiments, the braking device includes a support element, a block of friction material supported by the support element, at least one piezoceramic sensor supported by the support element and interposed between the block of friction material (and the support element, and a protective element located at the piezoceramic sensor and embedding the latter. The protective element can have one or more layers of resin-based material applied to protect the piezoceramic sensor and direct a predetermined part of the external compression force onto an area of the support element surrounding the piezoceramic sensor. In some embodiments, a signal transduction device is provided and includes at least one piezoceramic sensor supported on a support element and has an integral protective coating having properties of mechanical and temperature resistance.

Abstract: Various antilock braking systems, devices, and methods using sensorized brake pads are disclosed. In some embodiments, the present disclosure provides a method for improving the performance of an antilock braking (ABS) and anti-slip regulation (ASR) system of a vehicle. The method can include detecting the actual value of the coefficient of friction (e.g., between a tire and the ground), updating the coefficient of friction during braking using the braking torque data derived from at least one braking pad of each wheel, and adjusting brake force. For example, the brake force can be adjusted as a function of and/or to be approximately equal to the value of the actual tire-road friction during braking.

Abstract: A brake element is sensorized by at least one piezoceramic sensor arranged between a metallic support element and a block of friction material of a brake element, the sensor being completely embedded within the block. An electrical voltage signal generated by at least one piezoceramic sensor, without the need for a power supply, is picked up by an electrical circuit integrated into the metallic support element. The electrical voltage signal is processed in the form of equal length of samples per unit of time of the detected signal by successively processing in real time each sample of equal length of time sample of the signal by applying an algorithm. The algorithm is selected from at least one of a sequence of integrations of voltage values in the sample carried out in an interval of time in the order of milliseconds; FFT voltage data sample; and integral of the voltage data sample.

Abstract: A method in which at least one piezoceramic sensor and an electric circuit to collect an electric signal emitted by the piezoceramic sensor when subjected to a mechanical stress and possibly processing it are made as an electrically insulated unit. The unit is equipped with at least a branching ending with respective electric contacts and having the connected at least one piezoelectric sensor. The electric circuit and the at least one sensor are mechanically fixed integral with a first surface of a supporting metal element of a brake pad. Branching is formed so as to position the at least one piezoelectric sensor at a predetermined point of the first surface.
