Ford is joining other automotive companies in the development of a steer-by-wire system, as indicated by a newly surfaced patent filing.
This specific filing was made public by the United States Patent and Trademark Office (USPTO) on November 19, 2024, although it was submitted by Ford more than two years prior, on November 14, 2022. The focus of this document is not on the general concept of steer-by-wire, but rather on a particular functionality within such systems.
The steer-by-wire system removes the physical link between the steering wheel and the tires, which means there is no inherent resistance at the wheel when the car is stationary. Ford points out in its application that this could pose a concern for drivers who rely on the steering wheel as a grab handle when entering or exiting the vehicle, as it would rotate freely.
According to the details in the patent application, Ford proposes using sensors to detect when a driver is about to get in or out of the vehicle. This detection would trigger an actuator to apply torque to the steering wheel, securing it in position for those who wish to use it as a handle. This function would be more beneficial in larger pickups and SUVs, where passengers are more inclined to utilize the steering wheel for support when climbing in.

Steer-by-wire technology, first introduced by Infiniti in 2013 with its Q50 sedan, has garnered increased interest among car manufacturers over the years. Toyota has crafted its own iteration of the system, which is currently implemented in the Lexus RZ electric crossover sold outside the U.S., paired with a steering yoke. A patent application from 2023 suggested that Toyota may also consider adapting this technology for the U.S. market.
The Tesla Cybertruck makes use of a steer-by-wire system, and in 2019, Apple filed a patent application for its own version, as part of the tech company’s now-defunct electric vehicle initiative.
