A method for adapting the steering feel for a driver of a vehicle at an input element of the vehicle is described. The vehicle has a steer-by-wire steering system. The method comprises creating a reference of the steering feel. The method further comprises selecting scaling factors for the reference model such that characteristics of the steering feel remain constant for different steering ratios. The method further comprises adapting the steering feel using the scaling factors.

A method for controlling an electrically powered steering assistance system including an electric motor for providing assisting torque to an axle of a vehicle such that impact between a wheel and the wheel housing can be prevented. Electrically powered steering assist systems include an electric motor for providing an assist steering torque to the steerable wheels of the vehicle. The electrical current used by the electric motor has a typical dependence with the amount of output torque from the motor. The electrical current of the electrical current used by the electric motor exhibits distinguishable characteristics when the wheels reach the end stop in the wheel housing. By monitoring the electrical current used by the electric motor for providing the assisting torque it is possible to determine that the wheels have reached the end-stop.

The invention relates to a steering gear (11) for a vehicle having a helical gear (19), the helical gear (19) having a first gear wheel (21) and a second gear wheel (22) which engages with the first gear wheel (21), a first rotation axis (23) of the first gear wheel (21) being aligned so as to be transverse to a second rotation axis (24) of the second gear wheel (22), and an axis perpendicular (25) being aligned so as to be orthogonal to the first rotation axis (23) and to the second rotation axis (24), a smallest spacing between axes (26) between the first rotation axis (23) and the second rotation axis (24) coinciding with the axis perpendicular (25), and an engagement line (33) resulting by means of common contact points (34) of the two mutually engaged gear wheels (21, 22). In order to increase the diversity in terms of variants and/or to improve the adaptation possibilities, the steering gear (11) is characterized in that the engagement line (33) is spaced apart from the axis perpendicular (25).
