A steer-by-wire steering system for a vehicle, with a driver-operable control element for steering angle input, an actuating mechanism for setting a wheel setting angle, and a control unit which is configured, on a basis of a steering angle of the control element and a vehicle speed, to output a map for the setpoint of a position of the actuating mechanism. A wheel setting angle is able to be set by the actuating mechanism depending on a set steering angle and on a vehicle speed. A maximum settable wheel setting angle and/or a maximum settable steering angle is limited depending on the vehicle speed. A method is also described for producing a map for the setpoint of a position of the actuating mechanism, for example of the wheel setting angle, in a steer-by-wire steering system.
A steer-by-wire steering system for a vehicle, comprising:
A method for producing a map for a setpoint of a position of an actuating mechanism in a steer-by-wire steering system for a vehicle, comprising adapting a map by a control unit on a basis of a steering angle and a vehicle speed, such that a wheel setting angle that is settable by the actuating mechanism depends on a set steering angle and on a vehicle speed, and limiting a maximum settable wheel setting angle and/or a maximum settable steering angle, depending on the vehicle speed.
The steering system as claimed in 11, wherein the speed-dependent steering angle (x1), up to which the ratio between a deflection of the control element and the wheel setting angle set by the actuating mechanism is constant, and/or the speed-dependent amplification factor (a1) and/or the position of the turning point and/or the maximum settable wheel setting angle and/or the maximum settable steering angle are stored in a look-up table for different vehicle speeds.
