Method for estimating a steering torque (28), in particular for the lateral control of a vehicle (34), comprising the steps of detecting at least one signal on a current vehicle state and/or current vehicle environment, determining a desired steering angle (δ) by a steering control unit (42) 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 (δ) 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 (32) based on the corrected lateral force value, and estimating a steering torque (28) from the estimated self-aligning torque (32).
