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: A method of estimating wear of a vehicle brake element including at least a braking disk (10), a wearable block of friction material (20) and a support back plate (40) of the block of friction material (20), comprising at least: —providing a temperature sensor (100) configured and placed to sense the temperature of the support back plate (40) —providing an Electronic Processing Unit (200) connected to the temperature sensor (100); —providing an acquisition of the sensed temperature of the support back plate (40), a generation of a temperature signal of the sensed temperature and a transmission of the temperature signals to the Electronic Processing Unit (200); —and the Electronic Processing Unit (200) providing an estimation (500) of the thickness of the wearable block of friction material (20) by processing of the temperature signals.

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.
