A method for determining a driver's manual torque at a steering wheel of a vehicle which includes sensing a steering angle speed by a steering angle sensor, sensing a steering torque by a steering torque sensor at a steering column connected to the steering wheel, estimating a driver's manual torque applied by a driver at the steering wheel based on the sensed steering angle speed and the sensed steering torque by a Kalman filter by a controller, wherein during the estimation of the driver's manual torque a frictional torque is considered, and the frictional torque is estimated based on the steering torque which is sensed by the steering torque sensor, wherein the estimated frictional torque is taken into account as an interference factor during the estimation of the driver's manual torque in the Kalman filter. Also disclosed is an associated device.
