Can someone explain this to me like I'm a child? I mean, I can already K-turn in a car with no patented technology. This sounds different than tank turn, since wheels are spinning in opposite directions for that to happen. This just sounds like spinning the front wheels while dragging the rears. What does that accomplish?
Sounds like a low speed version of a J turn instead of a 3 point turn.

Looking at the full application, the broadest claims (the claimed scope of the patent) are for a K-turn (which is described as a turn with a pivot point somewhere beneath the vehicle) being accomplished by applying forward torque to front wheels and reverse torque (through braking or motors) to rear wheels.
Not sure that’s good enough for a child but, in short, I think this would cover a tank turn as well as just braking the rear inside wheel while powering forward with the front wheels.

Changes where the central pivot of the vehicle is. Ends up making a much tighter turn. They helpfully include vector math on the patent figure showing that the forward motion from the front tires cancels out with the backwards motion of the rear tires. The front of the vehicle will basically move sideways instead of forward at an angle.

Basically a tank turn plus steering. Think of coming up to a narrow trail point that is basically like a 90 degree turn that's too tight to make a turn into normally without scraping the sides. Now just shift the pivot point to between the rear wheels by rotating them backwards at the correct rate to maintain an "anchor", and steering the frontend around an arc to point the nose in the desired direction. Sure there's some sideways slippage of the tire, but you aren't making that turn without it. Handy. Works every time. Austin Powers - 3 point turn / maneuvering / parking Scene - YouTube

Doesn't the Bronco have this turn via one of the of road buttons? Tire drag turn or something?

Trail Turn Assist, but it uses the inside brake to get the vehicle to pivot. The K turn uses the rear inside tire moving backwards faster than the rear outside tire...and I assume the opposite to be true when maneuvering forwards, just that the rear outside tire would move faster than the inside tire to complete the turn.

I thought about that too. As Rivian’s application is written, the Bronco would infringe Rivian’s claimed patent. The Rivian application describes the turn being accomplished by having forward torque on the front wheels and a negative torque on at least one rear wheel. The rear wheel doesn’t have to spin backwards — in fact the patent application states it can be static in relation to the ground (not turning) to accomplish the K-turn.

Of course, keep in mind this is only Rivian’s application. It hasn’t issued as a patent. It is normal for an applicant to claim they’ve invented everything under the sun. The next phase involves Rivian negotiating with the patent examiner as to what they truly have invented, and this application may be much narrower when it actually issues as a patent.

US20210229514 - SUSPENSION WITH JOUNCE BUMPER BALANCED FOR CASTER CONTROL




Rivian R1T R1S Cool Rivian Patent/TradeMark Info m8jgAjupvrlM6NQ7oMOfxMZnxkL?docId=id00000110655226



Abstract
(EN)
A suspension includes a jounce bumper, and a striker. A spring biases the knuckle toward a first position. One of the spring and the jounce bumper is disposed forward of a kingpin axis of the knuckle and the other of the spring and the jounce bumper is disposed rearward of the kingpin axis. When in a first position, the spring is a first spring length. When in a second position, the spring is shorter than in the first position and the jounce bumper contacts the striker. When in a third position, the spring is shorter than in the second position and the jounce bumper is compressed against the striker to be shorter than in the second position. When moving between the second and third positions, the spring and jounce bumper impart moments on the knuckle that approximately balance each other to maintain a desired caster angle.

Even before the Bronco, the Landcruiser had turn assist which drags the tire for a tighter turn

AUTOMOTIVE VEHICLE SLIDING SIDE DOOR WITH DUAL GUIDE RAIL


https://patentscope.wipo.int/search...31&tab=NATIONALBIBLIO&_cid=P12-KTSSYG-77064-1

The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

Automotive vehicles typically have multiple doors for ingress and egress of vehicle occupants. For some vehicles, especially for larger vehicles such as minivans, a sliding door is sometimes used together with or instead of conventional swing doors. A sliding door may have various benefits over a hinged door, including functional benefits, ease of access, reduced outboard door swing, and avoidance of obstructions next to the vehicle.

Implementation of a sliding door design entails provision of sufficient space for the door mechanism and its components and may be limited depending on the vehicle type and styling considerations. In some instances, space constraints for various automotive vehicles may not permit for the utilization of a conventional sliding door mechanism. For example, space at the rear of the vehicle may not provide adequate room for the mechanism of a conventional sliding door. Additionally, a conventional sliding door does not travel the full extent of its own length during opening, and so the door opening in the vehicle body for ingress and egress may be partially obstructed by a forward portion of the sliding door. Thus, a conventional sliding door mechanism is not able to permit longer sliding door travel without the rear length of the vehicle itself being increased.

Are they.....putting a sliding door on the R1S??? Or a potential next model?? This seems way in left field, I'm curious.

Sounds like they're planning an adventure mini van, for those soccer games in wild places.

Rivian is all about filling the niche markets. This will help them coin the term "soccer dad" with a positive spin.
