Abstract: A method for estimating the residual torque between the braked and braking elements of a vehicle that is characterized by the following phases: acquisition of the temperature value of said braking element; determination of whether said brake is activated when the temperature value is acquired; acceptance of the acquired temperature value if said brake is not activated at said acquisition time; if the acquired temperature value is accepted, automatically calculating a reference temperature using input from an N-dimensional calculation model with an N-dimensional vector of input variables; where said N-dimensional vector of variables includes at least the acquired temperature of said braking element; where said N-dimensional calculation model is an analytical or experimental characterization of the thermal behavior of the brake; estimating residual torque by comparing the accepted acquired temperature to the calculated reference temperature.

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.
