Tesla's FSD hardware 4.0 to use cameras with LED flicker mitigation

By Nuno Cristovao

At Tesla's AI Day event last summer, Elon answered some questions during the Q&A portion of the event that revealed Tesla's plans for FSD hardware.

Elon informally announced that Tesla is already researching the next major hardware revision for full self-driving.

Elon said that he expects the current hardware in today's vehicles to be capable of "super-human" driving, but Tesla will continue to update their cars to have the most powerful hardware available.

Elon guessed that Tesla may release FSD hardware 4.0 with the introduction of the Cybertruck. Since the Cybertruck won't be released until the end of this year at the earliest, we may even see new hardware before its arrival, although this is unlikely.

In another question related to new hardware, Elon also said that Tesla is looking into new cameras. He was clear that the current cameras aren't a hindrance, but if Tesla can do better, then they will.

Elon didn't go into details about whether the new cameras would be tied to the Cybertruck or hardware 4.0. He also didn't mention specifically whether the new cameras would be higher resolution, contain larger sensors, or possibly even be placed in different locations.

Tesla currently utilizes three separate front-facing cameras in the housing at the top of the windshield. The camera unit contains wide-angle, standard, and narrow view lenses with three separate CMOS sensors.

Each sensor has a resolution of 1280x960 or about 1.2 megapixels.

According to Chris Zheng on Twitter, who has connections with some Tesla suppliers, Tesla is planning to use Sony's new IMX490 automotive sensor in their upcoming hardware 4.0 revision.

This new sensor offers many benefits over the current sensors that Tesla uses in their vehicles.

The new sensors support a much higher resolution of 2896x1876. That's 5.4 megapixels compared to the 1.2 megapixels that Tesla's current front-facing cameras support.

At more than four times the resolution of current sensors, these new sensors will allow Tesla to more accurately detect objects that are required for FSD.

Detecting road edges and lane markings that are further away are especially difficult. Due to the angle of the road and the current image resolution, Tesla often has to make assumptions based on just a few pixels.

The increased resolution will offer a more detailed image and should improve the accuracy in these situations.

The new wide-angle sensor may also allow Tesla to drop the number of cameras used in the front-facing module. Due to the higher resolution in these sensors, Tesla may be able to use this wide-angle sensor to interpret objects that previously required the use of the standard or telephoto lenses before. This may allow Tesla to reduce the number of cameras that are required in the front of the vehicle from three down to two or even a single lens.

The new camera sensor also supports HDR shooting at 10 bit and 40 FPS, offering better contrast and richer colors. It's not clear whether Tesla would take advantage of HDR as it would require more power to process, but it's something Tesla may consider depending on the compute power available.

More importantly, the new sensor will also support LED flicker mitigation. Camera sensors often have a hard time capturing the light emitted from LED lights in a constant fashion. Since LEDs are widely used in electronic signs and traffic lights this will be an important feature and should make it easier for Tesla to interpret such signs.

Tesla is working closely with Samsung to produce their next-generation chips that will be used in FSD hardware 4.0. Tesla will likely launch updated cameras at the same time they introduce a new FSD computer.

It makes sense for Tesla to introduce this new hardware in a new model first before retrofitting new camera modules into existing models.

Tesla FSD V12.5 to Enable Sunglasses-Friendly, Nag-Free FSD

Tesla has made some significant improvements with FSD 12.4, primarily, the removal of the steering wheel nag under certain conditions. However, there’s a caveat – you can’t wear sunglasses.

According to Elon Musk, FSD v12.5 will introduce support for nag-free FSD, even if you’re wearing sunglasses.

FSD V12.5 is an Upgrade

Ashok Elluswamy, Director of Autopilot Software, also took to X recently to mention that v12.5 is a big improvement to FSD v12.4. While he didn’t mention any specific details, this lines up with some of Musk’s previous comments that each FSD v12 iteration will see major improvements to the FSD model.

Elon also mentioned that while Tesla has a massive fleet of cars, their laser focus on making FSD work, rather than touting every daily achievement – has been their key to making generalized self-driving cars work.

FSD v12 has been pretty much a complete rewrite of the FSD city streets software stack, with drastic improvements over FSD v11. However, certain parts of the software stack haven’t been updated yet. Some features, like the updated highway stack are expected to be in FSD v12.5, which Musk confirmed recently. However, other features such as Park Seek and Banish Autopark, which were expected to arrive with FSD V12.4 are still up in the air.

What about V12.4?

FSD V12.4.3 is currently out to about 5% of the fleet (about 20-25% of FSD users) and hasn’t been pushed out again since about July 10th. Our new auto updating statistics pages can help break this down for folks who are curious.

Given that it’s been some time since any new vehicles have received V12.4.3, it seems the rollout has been stopped. There could be any number of reasons for this – including software bugs, or a lack of confidence with FSD. Additionally, it could just halted in favor of focusing resources on V12.5.

While we’d love to see more vehicles get v12.4.3, we’re likely to see v12.4.4 or v12.5 being the next big waves of deployments to customers. Either way, early-access testers and Tesla ADAS testers will receive these updates first, and then they’ll roll out to the vast majority of customers once Tesla feels confident there aren’t any major issues. Tesla does all this testing in the name of safety, and it's essential that bug-free versions of FSD are the versions that are rolled out wide.

So, for now, leave your sunglasses on and hang tight for the next FSD update.

Tesla Aims To Launch Cybertruck in Canada After Transport Canada Makes Exception for Steer-by-Wire

By Karan Singh

Tesla has confirmed that they’re aiming to launch the Cybertruck in Canada later this year. Transport Canada recently granted Tesla and the Cybertruck a unique exemption to allow steer-by-wire functionality (h/t Sawyer Merritt).

Steer-By-Wire Exemption

We previously reported that the Cybertruck was facing delays due to a steer-by-wire regulatory issue with Transport Canada. On Friday, July 19th, Transport Canada issued a message stating that they would exempt the Cybertruck, for all its models, from part of Canada’s Motor Vehicle Safety Act, which currently doesn’t permit the usage of steer-by-wire systems.

The period that the exemption begins seems to be immediate – July 19th, 2024, and will last through July 18th, 2029, whereafter regulation should supersede the exemption. In the meantime, Tesla will provide a semi-annual incident report, beginning on January 18th, 2025, including information on steering system malfunctions or failures, as well as corrective measures and customer complaints.

It seems that Transport Canada will also have to be notified every time Cybertruck’s steering software is provided with an OTA update, which could result in some update delays in Canada.

Canadian Cybertruck Soon?

With all this information, it sounds like Tesla is aiming to launch the Cybertruck to Canadian customers sometime relatively soon, as they stated they’re still aiming by the end of the year. There is a good chance that they may begin converting pre-orders to orders once Tesla. Tesla hasn’t commented on which model will be available in Canada, but it wouldn’t surprise us if it’s limited to the Foundation series in Canada in the initial release.

We could expect the first customer Cybertrucks (Roshel Defence and a few private importers notwithstanding), to be on Canadian roads in just a couple of months.
