摘要： 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.

摘要： A method in which at least one piezoceramic sensor, which converts every mechanical force to which it is subjected into an electrical signal and having a Curie temperature higher than 200° C., is solidarized directly onto the surface of a metal support element of a vehicle braking element, which during use faces a vehicle element to be braked. While in contact with such a surface, an electrical circuit is implemented that picks up and eventually processes the electrical signal, the electrical circuit being connected with a connector integrated with the metal support element. An electrically insulating layer sandwiches the at least one piezoceramic sensor and the electrical circuit, and a block of friction material with an underlying damping layer is formed upon the electrically insulating layer. After forming the block of friction material, the piezoceramic sensor is polarized by applying a predetermined potential difference thereto by means of the connector.
