Will The Revolutionary Tesla Windshield Wiper Debut On The Cybertruck?

The flat windshield on the electric pickup truck may be ideal for that.

We try to cover everything related to exciting patents on the EV world. Weirdly, we missed reporting about a revolutionary windshield wiper Tesla trademarked in September 2019. Like the innovative wiring harness it patented in July 2019, we have not seen it in any car so far, but what if it was applied to the Tesla Cybertruck? Some of its characteristics suggest this wiper would be a perfect fit for the electric pickup truck.

Before we talk about this perfect match, it is vital to understand how the windshield wiper design makes it be a revolution. It has a single wiper, even if it can also work with two of them. What makes it unique is using an electromagnetic moving block that slides along at lead one guide rail.

The best way to understand this is by imagining how a maglev works. The moving block would be like the maglev moving from one side of the windshield to the other. Attached to it, the wiper would be the sole friction source for obvious reasons. And that’s the main advantage it presents.

With less friction, such a windshield wiper would need less energy to work. As you already know, any way to save energy in an electric car impacts range. In Tesla’s case, there is another need: Autopilot and FSD work solely with cameras. This new wiper would ensure the windshield offers a better view than traditional systems.

Although we have no idea if Tesla will ever manage to make it work, the Cybertruck seems to be the best vehicle for the company to test it. Mostly because of its flat windshield, even if the windshield drawings show the unusual one adopted by the Model Y and Model 3 – remember the patent is prior to the Cybertruck reveal, on November 21, 2019. That would ensure an even surface for the new equipment to wipe.

The very first vehicles had flat windscreens due to the glass technology available at the time. They were slowly abandoned due to being more fragile and prone to break with stones or even larger insects that hit them, especially at highway speeds. In Cybertruck’s case, that is not a concern. The electric pickup truck will use aluminum oxynitride, also known as Tesla Armor Glass.

Another great take would be to eliminate windshield wipers as a whole, either with hydrophobic materials or aerodynamic solutions that created an “air wiper” to keep things clear. But this is something many tried before and never succeeded. If Tesla can make the maglev wiper reach production without reliability or quality issues, in any of its vehicles, that would definitely be a win.

Maglev isn't really much of an advantage here, since the bulk of the friction is in the wiper anyway. This same idea could be implemented with a standard threaded rod based motor if you could get it to slew fast, strong and quiet enough. Having space for such a motor at one end of the rail is likely to be neigh impossible, so you'd need to add a gear transition which would be noisy.

You know this how?

EVERYTHING you expect in a vehicle is subject to fundamental change on this thing. If side mirrors weren’t on this prototype, I expect none in production.

To compare: side mirrors on the Leaf affected aerodynamics enough Nissan changed the shape of the headlights to compensate. Same problem remains, and I’d not be surprised if Elon found a way to viably do without entirely.

The side mirrors are missing now on the prototype, but they will, be installed when they finally are delivered to customers.
Maybe...maybe not. Tesla has been an advocate for cameras instead of mirrors for a long time. Safer and more reliable. I believe they are legal in some parts of the world. Who knows...it could happen.

It is interesting to see that the Sentry side cameras are now also displayed into the central display below the rear view mirror camera.

So basically side view mirrors cameras are already existing on any Tesla vehicle.

I think that the new Honda e is sold in Europe using cameras instead of side view and rear view mirrors.

I wonder if future Tesla vehicles will get additional display screens on each side of the dashboard on keep the central display?

Cameras instead of side mirrors are not safer. If Tesla wants to install side cameras in addition to mirrors .. ok.
Anybody who has driven a truck knows the mirrors are needed. They are required by law too. That will not change.
The law will most definitely change, the only question is when (in my opinion). It's all about demonstration of reliability and increased safety. Insurance companies will demand it at some point.

I'm also in the camp that side mirrors will no longer be required someday soon, but I think as part of that there will be a requirement for a mirror-looking-display in pretty much the same spot as the driver sees the mirror now, but inside the car. Maybe attached to the dashboard, A-pillar, or even the door itself, but probably the A-pillar. It would eliminate air drag and potentially narrow the overall car(or conversely, allow the Cybertruck to be 12" wider with even more aero drag), eliminate mirror-icing, and stuff like that.

I often look in my Model 3 and think just such a display would work perfectly where the small tweeters are located on the A pillar. Exactly where you would look in a conventional car.

As cute as those linear/lateral windshield wipers might be, I don't think they'll make it --- not practical. Regular wipers only require a single point of motion/clearance/freedom whereas the linear track requires 2+ feet of freedom to travel which going to be plugged up, messed up, etc with all sorts of crap, leaves, dirt, bugs, etc....

Will the Cybertruck come standard with rear view mirrors? Yes. Should there be an option to replace them with cameras? Yes. Right now my side cameras notify me of things in my blind spots I cannot see in the rear view mirrors letting me know I need to stomp on the accelerator if I still want to change lanes. THE best part of owning a P3 is there is nothing 99% of the vehicles on the road can do about if I do.

The downside of the cameras is during bad winter driving the cameras frequently get obscured. I know that because they are constantly warning me about it. I cannot see out of the rear view mirrors either but they do not warn me. LIDAR or IR cameras covering the vehicle would probably be better but they can get likewise obscured.
