Method for estimating a steering torque, in particular for the lateral control of a vehicle, comprising the steps of detecting at least one signal on a current vehicle state and/or current vehicle environment, determining a desired steering angle by a steering control unit based on the at least one detected signal, estimating a vehicle lateral force on the basis of a tire dynamics model, including the determined steering angle as an input factor, estimating a vehicle lateral force on the basis of a lateral dynamics model, correcting the lateral force value estimated by the tire dynamics model on the basis of the lateral force value estimated by the lateral dynamics model, estimating a self-aligning torque based on the corrected lateral force value, and estimating a steering torque from the estimated self-aligning torque.
