Method and device for estimating a steering wheel torque for a mechanical feedback at a steering wheel of a steering system of a motor vehicle

A device for estimating a steering wheel torque for a mechanical feedback at a steering wheel of a steering system of a motor vehicle, comprising:

• an input for receiving and/or detecting at least one current measurement value of at least one state variable of the motor vehicle;
• a controller for estimating a current steering wheel torque and for outputting the estimated steering wheel torque as a steering wheel torque signal;
• wherein
• the controller is configured to conduct the estimation using a parameterizable steering model, to feed current measurement values of at least a subset of the at least one state variable as input data to the parameterizable steering model, and to estimate nonlinearities of the steering system based on the current measurement values of at least the subset of the at least one state variable using a method of artificial intelligence.
