Abstract: Methods and devices for estimating a residual torque between the braked (e.g., brake disk or drum) and braking elements (e.g., support plate or friction block) of a vehicle based on acquired and reference temperatures, where the reference temperature can be calculated using an N-dimensional calculation model with an N-dimensional vector of input variables, and where said N-dimensional calculation model can be an analytical or experimental characterization of the thermal behavior of the brake.

Abstract: Various systems, devices, and methods for a vehicle smart brake pad comprising a sensor such as a force sensing device, and a production process thereof. For example, a production process of a vehicle brake pad can include the following steps in time sequence: applying an electrical circuit a support plate; screen printing on the electrical circuit of at least a first electrode; screen printing on the at least first electrode of a sheet of piezoelectric material; screen printing on the sheet of at least a second electrode; applying a friction pad on the support plate; and bulk polarizing the sheet of piezoelectric material by a supply of power to the at least first and second electrodes.

Abstract: Various residual braking torque indication devices, systems, and methods are described. The devices, systems, and methods can include a sensorized brake pad. An output signal of the sensorized brake pad can be processed to provide an indication of a residual braking torque. The residual braking torque indicator can be calibrated to reference data to provide an actual measurement of the residual braking torque.

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.
