Tesla has released vision Park Assist with Tesla update 2023.6.9
@EVBaymax & @ManZoneBeer
Tesla has unveiled the Vision Park Assist feature with its new software update, version 2023.6.9 for non-FSD Beta vehicles. This cutting-edge feature employs the car's cameras to measure distances to nearby objects, offering users valuable parking assistance.
When Tesla removed ultrasonic sensors (USS) from their vehicles six months ago, some owners expressed concerns regarding the loss of parking assistance. In response, Tesla embarked on the transition towards a vision-based solution, culminating in the introduction of Vision Park Assist.
Accuracy of Park Assist
Twitter user @EVBaymax couldn’t wait till morning to test out the new Vision Park Assist feature. Equipped with his Model 3 and a measuring tape, @EVBaymax put the new technology to the test and shared it all on Twitter, providing some valuable insight into its performance. In one video, he said, “super-impressive what Tesla has been able to do. This is… Wow! I’m impressed.” @EVBaymax was showing the car within an inch or two of what the reading said inside the car.
However, he did spot something less impressive. When shifting into drive or reverse after being parked for a few minutes, a message pops up that says: Park Assist is Loading. That load took 6-8 seconds as the system recalls what was around it before it was parked. The time is quite a lag compared to the USS-enabled systems. @EVBaymax is hopeful this is addressed. However, the vehicle did eventually load the data it had before it was turned off, showing the same distance to the curb that was in front of it, even though the curb was out of view of the cameras.
Several online videos show a significant difference in readings between USS and Vision. USS mostly displays smooth readings with straight edges, but vision does not display many straight lines. When backing up to a curb, @EVBaymax notes that the line representing the curb is “squiggly and is moving.”
Availability
Although Park Assist was initially included in FSD Beta 11.3.2 and limited to North American markets, Tesla is rolling out Park Assist to additional markets with update 2023.6.9.
Currently, the Vision Park Assist feature is compatible with Model 3 and Model Y vehicles. Users also have the option to turn off Park Assist if they prefer, just like owners with USS. This innovative technology offers 360-degree detection, instead of just front and rear, as highlighted in our previous article.
Park Assist Detecting a Curb
One of the advantages of vision-based Park Assist is the ability to detect objects on the side of the vehicle. @EVBaymax does a great job illustrating that in this video below.
At this time, it appears that vehicles with ultrasonic sensors still offer a higher level of accuracy, however that could depend on the height of the object and the type of object itself.
Vision Park Assist does not currently apply to vehicles with ultrasonic sensors. However, since Vision Park Assist does provide some advantages over its hardware-based version, it'll be interesting to see if Tesla incorporates it into all vehicles in the future as the feature matures.
As more Tesla owners install and utilize Vision Park Assist, the feature is expected to improve. The company will use the collected data to enhance distance estimates, aiming for accuracy on par with sensor-based systems.
Tesla's Vision Park Assist offers visual and auditory alerts for objects in the vehicle's surroundings, utilizing the occupancy network to generate high-definition object outlines. However, it is essential to remember that this feature should be treated as guidance, not as a substitute for an attentive driver.
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.
Thanks to Greentheonly for helping us understand what happened with this release and for the insight into Tesla’s processes.
