Abstract
Steer-by-wire steering systems for vehicles and related methods are described herein. An example steer-by-wire steering system includes a steering wheel angle sensor to detect a current steering wheel angle (α) of a steering wheel of the motor vehicle, a steering actuator to generate a variable steering torque on a steerable wheel of the motor vehicle, a steering angle sensor to detect a current steering angle (β) of the steerable wheel, and a steer-by-wire controller to process signals from the steering wheel angle sensor and the steering angle sensor and control the steering actuator based on the signals. The steer-by-wire controller is configured to vary a transmission ratio between a change in the steering wheel angle (α) and a change in the steering angle (β).
