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.
