Could Tesla be upgrading the repeater camera with a wider angle?
Cyber Owners/YouTube
Tesla continues to roll out Full Self Driving and has also increased the cost of FSD. The system is logging millions of miles and constantly improving as Elon Musk continues his quest to make driving safer, preventing injuries and saving lives. However, there are still many skeptics of the program that has the potential to revolutionize transportation as we know it.
Some of Tesla's most prominent supporters are its harshest critics, but Musk said at the Tesla shareholders meeting in August that he welcomes honest evaluations. The YouTube channel for CyberOwners has a truthful, well-explained assessment. Mike Hoffman of CyberOwners demonstrates and clearly explains one of the most significant issues with Tesla's ability to see its surroundings and navigate safely. The blind corner.
Video Explanation
We've all encountered these situations while driving. Something obstructs our view, and we must lean over the steering wheel while slowly creeping forward to see if it's safe to proceed. As Hoffman shows, the current camera setup has a large area it can not detect. But there are solutions, some that would cost a lot of money and some that could be a simple camera swap.
Hoffman believes Tesla may already be testing a new repeater camera. The repeater camera, more commonly known as the blind spot camera, is on the front fenders. These cameras capture video to the side and back of the vehicle. But Hoffman noticed something different in a video posted by Ashok Elluswamy (below), Tesla's Director of the Autopilot Program.
It appears the program is gathering data from the repeater camera that is further forward than the current camera view. There is also speculation that the video Elluswamy shows is from the b-pillar, the one that is between the front and rear doors. Hoffman says the camera sees much further ahead and is convinced a new repeater camera is being used.
Alternative solutions to this blind corner dilemma include adding cameras to the front bumper and fog lights or moving the b-pillar camera to the side mirror housing. However, this would require new cameras and wiring, which would mean the computer would have to analyze more video streams. This action would be a considerable cost for Tesla, and Hoffman believes a camera swap is much more probable.
Hoffman might be right. It would not be the first time Tesla has changed the repeater camera. When a software update in 2021 included the blind spot feature, some users discovered the repeater camera had glare and was not much help. Tesla changed those cameras out for free.
Most of Tesla's cameras are made to be quickly swappable. Repeater cameras and b-pillar cameras can be swapped out in less than five minutes. That said, this change would require Tesla to swap out potentially millions of cameras. Not a cheap solution, but perhaps the best one to improve another aspect of a system on the cutting edge of technology.
Tesla’s been on a roll with Supercharger improvements lately, from the 325kW charging update for the Cybertruck, to 500kW with V4 Superchargers coming next year. While those improvements have been limited to the Cybertruck, Tesla didn’t put all their focus on their new flagship vehicle, but looked at their more affordable vehicles as well.
LFP Battery Heating
Tesla’s Superchargers can now heat LFP Batteries - those that are in the Model 3 and Model Y Rear Wheel Drive variants. This applies to Long Range and Standard Range models, which saw a limited run. This is another update included as part of the 2024 Tesla Holiday Update - which really arrived with a lot of unannounced new features and capabilities.
The change is pretty interesting - Superchargers of the V3 and V4 variety can now pre-heat batteries for Model 3 and Model Y vehicles equipped with LFP battery packs. That means those vehicles are able to get back on the road faster when it's extremely cold. Of course, Tesla still advises you to precondition before you arrive, saving drivers time and money.
Max de Zegher, Tesla’s Director of Charging, also commented on the new feature. Essentially, Tesla is inducing an AC (alternating) ripple current through the battery to warm it up. Keep in mind that Superchargers are DC charging. That means it is possible to get a cold-soaked LFP vehicle on the road 4x faster than before, assuming that it didn’t precondition at all and that it is in the worst-case scenario (below 0ºF).
In essence, Tesla is using some engineering magic to turn the circuits inside the LFP battery into an electric heater - and powering that heater through the Supercharger. An AC ripple current is a small oscillation in the DC charging current that generates heat through electrical resistance, warming up the battery. Those ripples are a byproduct of converting AC to DC and back - so Tesla is using the onboard charger to induce those ripples to warm up the battery. Definitely an innovative technique that’s really only possible with the versatility of the NACS connector.
We’re hoping Tesla can implement this across their full lineup of vehicles, but we’ll have to wait and see how it is trialed across LFP vehicles first and if it is even possible on vehicles with 2170 or 4680 battery packs.
Tesla launched two FSD updates simultaneously on Saturday night, and what’s most interesting is that they arrived on the same software version. We’ll dig into that a little later, but for now, there’s good news for everyone. For Hardware 3 owners, FSD V12.6.1 is launching to all vehicles, including the Model 3 and Model Y. For AI4 owners, FSD V13.2.4 is launching, starting with the Cybertruck.
FSD V13.2.4
A new V13 build is now rolling out to the Cybertruck and is expected to arrive for the rest of the AI4 fleet soon. However, this build seems to be focused on bug fixes. There are no changes to the release notes for the Cybertruck with this release, and it’s unlikely to feature any changes when it arrives on other vehicles.
FSD V12.6.1 builds upon V12.6, which is the latest FSD version for HW3 vehicles. While FSD V12.6 was only released for the redesigned Model S and Model X with HW3, FSD V12.6.1 is adding support for the Model 3 and Model Y.
While this is only a bug-fix release for users coming from FSD V12.6, it includes massive improvements for anyone coming from an older FSD version. Two of the biggest changes are the new end-to-end highway stack that now utilizes FSD V12 for highway driving and a redesigned controller that allows FSD to drive “V13” smooth.
It also adds speed profiles, earlier lane changes, and more. You can read our in-depth look at all the changes in FSD V12.6.
Same Update, Multiple FSD Builds
What’s interesting about this software version is that it “includes" two FSD updates, V12.6.1 for HW3 and V13.2.4 for HW4 vehicles. While this is interesting, it’s less special when you understand what’s happening under the hood.
The vehicle’s firmware and Autopilot firmware are actually completely separate. While a vehicle downloading a firmware update may look like a singular process, it’s actually performing several functions during this period. First, it downloads the vehicle’s firmware. Upon unpacking the update, it’s instructed which Autopilot/FSD firmware should be downloaded.
While the FSD firmware is separate, the vehicle can’t download any FSD update. The FSD version is hard-coded in the vehicle’s firmware that was just downloaded. This helps Tesla keep the infotainment and Autopilot firmware tightly coupled, leading to fewer issues.
What we’re seeing here is that HW3 vehicles are being told to download one FSD version, while HW4 vehicles are being told to download a different version.
While this is the first time Tesla has had two FSD versions tied to the same vehicle software version, the process hasn’t actually changed, and what we’re seeing won’t lead to faster FSD updates or the ability to download FSD separately. What we’re seeing is the direct result of the divergence of HW3 and HW4.
While HW3/4 remained basically on the same FSD version until recently, it is now necessary to deploy different versions for the two platforms. We expect this to be the norm going forward, where HW3 will be on a much different version of FSD than HW4. While each update may not include two different FSD versions going forward, we may see it occasionally, depending on which features Autopilot is dependent on.
