The invention relates to a method for estimating a steering wheel torque (11) for mechanical feedback on a steering wheel (55) of a steering system (52) of a motor vehicle (50), comprising: receiving and/or detecting at least one current measured value (5-x) of at least one state variable (51-x) of the motor vehicle (50) via a suitable input means (2); estimating a current steering wheel torque (11) by means of the controller (3); outputting the estimated steering wheel torque (11) as a steering wheel torque signal (12); wherein the estimation is carried out by means of a parameterizable steering model (6), the current measured values (5-x) of at least a subset of the at least one state variable (51-x) being supplied as input data to the parameterizable steering model (6) for this purpose, and wherein a nonlinearity (10) of the steering system (52) is estimated by means of an artificial intelligence method (9) on the basis of the current measured values (5-x) of at least the subset of the at least one state variable (51-x). The invention further relates to an associated device (1) and a motor vehicle (50).
