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 (&#x3b1;) 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 (&#x3b2;) 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 (&#x3b1;) and a change in the steering angle (&#x3b2;).

Steer-by-wire steering systems for vehicles and related methods

A motor vehicle including a steering mechanism, a steering gear mechanically decoupled from the steering mechanism, a drive unit for driving the steering gear, and a transmission unit connecting the drive unit in a torque-transmitting manner to the steering gear. The transmission unit including a first torque transmission path and a second torque transmission path wherein the transmission unit has a redundancy.
