Suddenly speed up after disable autonomous driving

[kozakurayuua]

Hi guys
Any one has the experience when we push up right stick to cancel autonomous driving, occasionally the car speed is increasing instead of decreasing as expected? I almost hit front car and must use break, of course the system gives me a "hard break" and decreased my safety score. ( Although it's a miner,but I don't like it) Well, I thought 3 seconds rule should be applied but a big NO. I got this again today. The firmware is the latest 2022.12.3.12. MYP. The location is at the south exit 382 of highway 101. I turned right to central expressway. (It's a strange location, autonomous driving almost fail at that exit everytime )

Thanks

If you push up on the gear shift and hold it for a second or more, the car shifts into neutral. Any chance that's what happened to you?

Yeah, that's one thing hope to know how you guys cancel the autopilot? I always judge by hearing the "ding-dong" when I disengage the autopilot or kick it in. In a heavy traffic area, I barely have time to check the screen. (I am always very nervous when behind the wheel) Thanks for your feedback, I will check if it's shifted into neutral or not next time.

I usually just tap the brake if I want to cancel AP. Using the gear shift is clunky.

Since I have FSD beta, it's been a while since I've used AP, but as I recall, if you disengage AP by only turning the steering wheel, TACC remains active, so the car might unexpectedly speed up if traffic opens up ahead of you. I know this happens with FSD beta.

Raising the right stalk or tapping the brakes always puts the car into manual operation.

Tap the brake. It's as easy as it gets

I always push the gear shift up to cancel autopilot and it has never accelerated. Starts regen breaking right away unless I hit the pedal.

I am on the same version as you.

just press the lever up, how is that clunky?

I find it clunky, and there's a slight chance that you'll accidentally shift into neutral. Do what works for you.

I usually tap the lever up - never had any problems accidentally going into reverse. I guess either works for me, whatever happens to be most convenient.

As far as the original question is concerned I’ve never had anything like that happen. My first thought was that s/he disengaged AP but left TACC on.

That was my first thought too, but I think the only way to cancel Autosteer but leave TACC enabled is to steer manually. Also, even if TACC remained on, I don’t know what would make it speed up under those conditions. Hopefully the OP will figure it out and enlighten us.

Hi All
Thanks for the inputs.
I seem found the root cause. sometimes, I subconsciously use the right lever as a turning signal. The car jumps into AT again. I have to get rid of the habit.

 

[sleepydoc]

Well, that would explain it! Why do you use the right stalk as a turn signal? The left stalk is such a universal control it seems like an odd thing to mix Up.

It’s not universal. Many makes have the indicator stalk on the other side

I believe you, but I cannot think of an American manufactured automobile with the signal stock not on the left-hand side. So, please, name same makes worth the signal stalk on the right-side.

There aren't any American manufacturers I know of. It's easier for you to Google the topic. It's an over-discussed subject.

Over discussed yet you couldn’t name one lol.

You can’t shift into neutral while in motion… it literally tells you you can’t if you try

Not true, and I tried it this morning in my wife's Model 3 to make sure. If you push up on the gear stalk (when in D) but don't hold it long enough, you'll see an alert message saying you have to hold it up for 1+ seconds to engage neutral. If you do hold the stalk up long enough, you won't see the alert and it will shift in neutral.

Correct. And if you are driving slow enough, you can put the car in reverse without stopping (usually).
