So much for the heated radar (gen 2) - EDIT: IT WORKS!

[FraserC]

I wonder if there is some type of application you can apply to the front so that snow has more difficulty sticking?

Rainex (or similar) might be worth a try.. I've used it for years on the windshield and it definitely weakens the bond between frost and ice and the glass.

I've tried Rain-X on cameras before, and while it does work, it only lasts one or two rainstorms before no longer repelling anything.

A while back there was a video where a Rivian engineer was talking about safety and repairability changes made to Gen 2. In that video he mentioned a heater grid for the radar to prevent ice/snow buildup. Unfortunately I am having a hard time finding that thread again

Utah has had an unusually dry winter thus far, but this morning we had snow for the first time in about a month. I took my R1S out in the snow for the first time this morning on the way to the gym. It did wonderfully for the first 20 minutes or so (highway assist, lane changes, everything great). But then I got the "sensors blocked" message. When I got to my destination there was, indeed a layer of slushy ice covering the entire front of the vehicle. A relatively thin layer, but it was there.

So... What gives?
I'm thinking there are 3 options
1) mine is broken
2) the engineer misspoke and there's no heater over the radar
3) I don't know how to activate it

As a sanity check I RFTMed and there's 0 mention of a radar heater that I can find.

If it does exist, is it activated alongside the window and side mirror defroster? Has anyone else played with this?

The Teslas do the same thing.

If a heated radar existed, wouldn't the activation tie with the heated mirrors instead of the rear window defrost? It would be worth a shot of activating the heated mirrors to see.

The heated mirrors and rear window are on the same button. You can't activate the mirrors alone. But I didn't try that button. So I'm going to do that next time it snows

Do you think it's possible they are integrating the Rivian system with the Mobileye? What I mean is right now the Mobileye is running the ADS but could the lane gap thing where it slows down or speeds up to make a lane change be Rivian's?

Rivian already does integrate the two, but not in the way you're describing. The MobilEye system is a black box to Rivian. It gets data out of, but doesn't feed data into, it. The ADAS, RAP in the case of Gen 2, uses it as a sensor. It will be replaced in software with Rivians stack once Rivian's implementation is ready.

Since we're on a rant anyway, I also suspect that's why we don't get regen on cruise or Highway assist. Mobile eye does not understand what Regen is. It's an off-the-shelf system meant to fit any vehicle. So all it knows is "brake"

MobilEye doesn't run the ADAS. And regen is still absolutely used with ACC and HWA. Friction brakes are slightly activated, and the pedal moves slightly, but the primary braking force is regen.

if only they could software update a front radar heater

It's far from scientific, sure. but I would not describe the brake pedal movement as slight on my vehicle. It moves pretty far when braking on HWA or ACC. When slowing down with just manual driving it will not move, even a little until I'm near a stop. (I do have regen assist turned off so I have a more clear indication of how much is regen vs friction brakes)

I've never heard of this capability in the R1 series. I am however confused how it's even remotely safe to "I took my R1S out in the snow for the first time this morning on the way to the gym. It did wonderfully for the first 20 minutes or so (highway assist, lane changes, everything great)."

How is it driving safely in ice/snow conditions to have highway assist on (enough to frost up the front of the car)? By the time an unanticipated skid/slide is initiated, highway assist cuts loose, and you've attempted to (likely over) correct, at the very least you'll be in the ditch. Please people, drive safe out there for the conditions.

I’m fairly confident, like others, that Mobileye “supervision” is providing all of the adas functionality in gen2 atm, the hardware in the gen2 R1’s is compatible with it - and the entire feature set both today, and promoted as coming soon, is exactly what “supervision” provides. Over time Rivian will want to divest itself of reliance on mobileye hardware and software, so I’d be surprised to see them feed the vector data provided by Mobileye into RAP. I would love to be proved wrong but I don’t think the RAP platform is doing much of any thing there yet - let’s hope this time round they can change the narrative.

Well at the very least I think they're collecting data and training their machine learning model. I suspect the virtualization are from the rivian system too

Sure - I should have specified that while I don’t think RAP is actively doing anything, 100% agree they are collecting data - this is implied by some of the options in the settings page for data sharing - though I forget the wording offhand, right now if you don’t share the internal camera data with Rivian, they simply disable it. The visualization is an interesting one - it’s probably where we will see rivians own models used 1st, but id Expect them to want to keep the adas platform consistent across both visualization and actuation for some time.

On multiple occasions I've watched my Rivian's network connection light up when it gets home and connects to Wi-Fi. It will immediately upload anywhere from 5-25 GB of data to Amazon servers every time I come home and it connects. That amount of consistent data has to be video/training data.

This is certainly not conclusive, but there are a couple of things I've seen that lead me to think the visualization is not coming from mobile eye:

1)The lane lines do not always line up with the position of the cars. I'll see the car visuals jump around quite a bit while the lane lines stay completely steady (or vice versa)
2) on multiple occasions I've had the visualizations completely break to where only the "lead vehicle" directly in front of me is shown, along with lane lines. In every instance where this has happened the ADAS remained 100% functional with no degradation.

That leads me to believe that the lane lines are from mobile eye and the rest of the visualizations are from the Rivian System's cameras. If there's a malfunction with the rivian system the visuals fall back to mobile eye with just the lead car.

I've also noticed the visuals making HUGE strides in fidelity and accuracy in the last 3 months. Way faster than I'd expect mobile eye to improve

So certainly nothing conclusive. But it does seem to add up to some degree

They absolutely use a MobilEye system, but only the outputs if their Gen 1 methodology is any indicator. Some background:

In an interview with “The InEVitable” podcast, Scaringe emphasized the limitations of Mobileye’s system for Rivian’s long-term goals in autonomy.

On Thursday, Mobileye shares crashed 22.48% percent to a new all time low of $16.28 per share.

“Gen 1 [R1T and R1S vehicles] had a collection of cameras. Importantly, the front-facing forward camera is a Mobileye-based system,” he noted.

“As a result of that, architecturally, it meant that we have a late fusion of information, because we take a camera that’s forward-facing from Mobileye that does a lot of processing, and it doesn’t give us RAW. The output of that is it detects objects, it classifies the objects, and assigns vectors to those objects,” Scaringe detailed.

The new Generation 2 (Gen 2) platform will feature a completely revamped camera system developed internally by Rivian, comprising 55 megapixels worth of cameras and five radars, including an imaging radar.

“Architecturally, that approach makes it very hard to use an AI-centric model, where you’re collectively using the full perception stack, having an early fusion, using more advanced AI training techniques to collectively assess from a perception point of view, what’s around you, and then using that to drive both the planning side, the path planning side, and then, of course, the controls. What went into Gen 2 is a whole new camera set. We have 55 megapixels of cameras.” the chief executive said.

With the in-house developed solution, Rivian will be able to increase by 10 times its compute power.

“We developed the cameras in-house. Five radars, including an imaging radar and the front-facing radar. Significantly more compute, about 10x the compute,” Scaringe stated.

“Moving away from Mobileye allows us to leverage early fusion and more advanced AI training techniques,” Scaringe said. This approach is expected to enhance the vehicle’s perception and path planning capabilities, paving the way for more sophisticated autonomous features in the future.
