Filed with the United States Patent and Trademark Office in September 2020 and published March 31 of this year,
is for"crawl operations for four-wheel steering vehicles." An accompanying image shows a previous-generation Ford F-150 Raptor , but with front and rear motors, indicating this system will be used with electric trucks.One thing Ford describes is turning the front wheels in one direction, and the rear wheels in the opposite direction. By applying power, this would allow a vehicle to move sideways left or right on a loose surface, the automaker claims.
Ford doesn't stop there, though. The automaker also describes steering the wheels individually. That means the wheels on either axle could be turned in opposite directions, with one wheel pointing left and and one pointing right. Such a system would likely be reserved for off-road use. Ford specifically mentions loose surfaces like snow, sand, and mud, but not pavement. The automaker seems to think this setup could help if a driver gets very stuck, as turning the wheels in different directions could potentially gain traction.As with all automotive patents, though, there is no guarantee that this elaborate steering system will make it to production.
These guys need to stop patenting what others already have done. 🤣🤣
