Tesla Update Returns Automatic Emergency Braking To Impacted Vehicles

Well, if this works as planned, Consumer Reports will have yet another Tesla story to publish.

We recently shared the Consumer Reports story regarding Tesla turning off automatic emergency braking on some of its vehicles, while the new system underwent validation. Basically, Tesla changed out some hardware and had to assure that the system was functioning properly after the change. According to Consumer Reports, the automaker said it would take about six weeks to complete the validation. It’s been four weeks since then, so Tesla is actually ahead of schedule. An automaker spokesperson stated:

Tesla

Model S Automatic Emergency Braking Test

“We recently introduced some minor hardware changes to the Autopilot system in new cars, and we are now in the process of robustly validating the new hardware using real-world driving data. During that process, Automatic Emergency Braking will temporarily be inactive and will instead be in shadow mode, which means it will register how the feature would perform if it were activated, without taking any action. This temporary calibration period is standard Tesla protocol and is done out of an abundance of caution.”

During the validation period, the automaker had the feature engaged in “shadow” mode in all affected vehicles. Tesla reminded that this type of calibration is standard for its vehicles due to continual hardware updates and the over-the-air software update system.

Although this process may cause an inconvenience to owners, it provides the safest situation and assures that all vehicles are incrementally up to date. In a traditional OEM situation, something of this nature may require a recall. Additionally, to get new hardware and updated software in OEM models, you generally need to purchase a new car. Legacy automakers make these type of updates on a model year basis and only to certain models or trims, rather than continuously and fleet-wide.

Tesla is currently updating all impacted vehicles to have full-fledged automatic emergency braking. So, it seems the system must be working as planned. According to Electrek, the feature will still be limited to 50 mph, but this is an improvement over a previous limit of 28 mph. The latter limit is one that Consumer Reports equitably held against the Silicon Valley automaker when it chose not to upgrade the vehicles’ safety ratings.

The automaker is eventually expected to remove the limit on speed so that the feature will work at highway speeds.

    Consumer Reports needs to start paying Tesla royalties, for all the free publicity CR is getting by riding the coat-tails of Tesla’s popularity. 😉

    And regarding Tesla actually being ahead of schedule: Tesla had better be careful, or that might become a habit! 😀

    1. Pinewold says:

      Since the most useful case for AEB is on a highway, 50 miles an hour is not enough and Consumer Reports may not fell obligated to change their rating yet. Since there is still more work to be done, say delivery is early seems premature.

      1. scottf200 says:

        Is there proof that AEB is engaged more at highway speeds >50? I would rather expect stop and go traffic on highways or around town in 40-45 speed limit zones.

  2. zzzzzzzzzz says:

    Bare bones $17k Corolla LE has AEB as standard feature, functional up to 110 mph and not confused by “too bright sky”, “white trailers” or overhead bridges.

    Now these $100k supposedly “luxury” and “bleeding edge” cars can’t get AEB functional even at 50 mph and need people inside as guinea pigs to do their testing?? What a brainwashed idiot fanboy can cheer such?

      Not capable of steering itself down the highway, either. Thank goodness Tesla has such high aspirations.

      I guess you’re in no danger there, zzzzzzzzz.

      1. Four Electrics says:

        If Teslas cannot autostop, perhaps they shouldn’t autosteer (or auto-go). For an allegedly safety-focused company, Tesla sure is confused about the proper order in which to do these.

    2. Nix says:

      Who says they can’t get it functional above 50 mph?

      They just haven’t released that part of the feature to the public yet. That doesn’t mean that they haven’t already gotten the system completely functional in test cars at 50+ mph.

      It is sad when some folks confuse a high level of due diligence and very conservative approaches to safety with inability. They are not the same.

      1. Four Electrics says:

        I, too, have implemented AEB, as well as full level 5 self driving, in my own yet-to-be-released car. I’m pretty conservative about releasing it, though. Just ask my girlfriend. If you can find her, that is. She’s… in Canada.

        In all seriousness, the conservative move is to not release a car unless all safety features work. Imagine a car where the seat belts were “coming soon.” For shame.

    “Impacted”? I see what you did there.

  4. Nix says:

    I can see this story is already headed to massive concern trolling. We had that with the original story, and it all turned out to be overblown.

    But the same folks who made the issue overblown aren’t here to admit they they went completely overboard over something that is being addressed in weeks. They are here to do it all again.

    Sad.
