Cruise Control Bug Not Fixed by 2020.8.1

edited November -1 in Model 3
I installed 2020.8.1, hoping the cruise control bug that prevents the plain old cruise control from engaging immediately after it’s set while driving up a grade would be fixed by the update, but it wasn’t.

Please fix this, Tesla.

    I must have just learned a new behavior, then because this doesn't bother me any more

    Sorry, I know this was discussed but I can’t remember, does the OP not have AP? Otherwise he’s misusing the term plain old cruise.

    There is no spoon responses are odd.

    What responses are those? If the car has AP or EAP it doesn’t has plain old cruise. Only early cars have that possibility

    I made note of the behavior that the OP brought to our attention because I saw it as well. I have HW3+FSD. So it really doesn't matter if the OP has regular cruise, AP, EAP or FSD, it does occur.

    That said, I guess I've just figured out how to engage TACC and AP without triggering the behavior, so it doesn't bother me any more. I'm now chalking it up as another "Right way, wrong way, Tesla way"

    (Borrowing from an old Navy saying: There's the right way, the wrong way and the Navy way. The squids who are reading this know what I'm talking about.)

    Not disputing its occurrence, just didn’t know if it was indeed limited to cars with only dumb cruise. If so, I wouldn’t be able to replicate it. I also don’t have any hills on my daily commute.

    Plain old, old fashioned, dumb, traditional cruise control is what I use. I do not use TACC or AP. I keep my attention on driving when I’m driving.

    I figure that if I use the word “bug” often enough, someone at Tesla might fix the problem. ; )

    Remind me again how to engage plain ol’ cruise control? I am soooo interested in this function as I rarely engage TACC.

    Sorry still confused a little by the way you state that you don’t USE TACC or autopilot. The only way to have dumb autopilot is if you purchased before AP was included and don’t have it or EAP. Otherwise one tap down is TACC.

    My car was delivered in October 2018, and I have neither Autopilot nor Full Self-Driving. Didn’t want them. Still don’t.

    Ok, that’s makes sense. It was the wording, “I do not to use” that I wasn’t sure about

    So after tapping down, you are pulling your foot off quicker than whatever mechanism the car uses that actually moves the pedal is fully engaged. Is that your complaint?
  • edited March 15
    Although there is no physical cable pulling a butterfly valve of a carburetor, the throttle control emulates that with a pedal that travels. If it were a touchscreen or a pressure transducer than the electronics could take over immediately. However, since you expect the pedal to be in the correct position for your foot to reengage after cruise is off, it mechanically has to be moved. What you’re experiencing is a little lag time for that to happen.

    Man, are you persistent. I am not using the car wrong.

    I live on a hill in a very hilly area, so I’ve had lots of opportunities to try lots of things. I’ve tried lifting off of the accelerator immediately after setting the cruise control, after a short pause, after a long pause and after a verrry long pause. I’ve tried toggling the set speed with the thumb wheel after setting the cruise control, but it still won’t engage without first decelerating significantly, sometimes up to 13 miles per hour.

    There’s definitely a bug in the system.

    Bug. Bug. BUG!

    Since you can replicate it and it is unsafe, pick a spot close to nearest Service Center where you can demonstrate. Go to SC and ask tech to take ride with you to observe problem and how to duplicate.

    If you are lucky, tech will say we can fix it and can duplicate to fix it.

    If unlucky it will be the dreaded "within normal limits" and your bug is a feature.

    Why would one feel the need to engage cruise control near their home, on a hill?

    ANY grade, anywhere.

    Someone once told me that “just because you can, doesn’t always mean that you should”

    Maybe thats the fix!

    Be nice. What PECo CT is reporting would be annoying as hell to me, and should be reported to Tesla as a bug. RayNLA, I don’t understand your desire to minimize that.

    Just recognize that Tesla doesn’t monitor these forums, and no one on here can help you. You’ll need to get someone s attention inside Tesla if you actually want this fixed.

    Ok...I’ll be nice. Thanks for the reminder. :)
    I think you summed the situation up completely by stating that no one here can help you.
    But I still question the use of cruise control anywhere near a residential area. Or maybe i’m misinterpreting the scenario that the OP described.
  • edited March 15
    Thanks for provided some details. Still need more though. Traveling uphill at a steady speed, tap down once, car indicates it’s in cruise, lift foot, car slowed down, then speeds up to where it was set? Is this your complaint?

    I’m a little confused by the statement “ but it still won’t engage without first decelerating” does cruise not engage when you tap down? Does it accelerate with the thumb wheel but when you lift your foot, it still slows down?

    When you turn the thumb wheel, the pedal should move down away from your foot, I’m still confused by your description, not just trying to tell you you’re doing it wrong.
