Tesla V9 Has New Feature To Prevent Unintended Acceleration

Crashed White Tesla Model X

No more wall hitting, okay?

Over the past several years, from time to time there were reports that Tesla drivers crashed because of unintended acceleration – it was unintended by the driver, who wanted to stop, but we believe that at least in most cases it was driver error by confusing the acceleration and braking pedals.

Tesla would’ve been in trouble if there was a technical/software problem that would accelerate the car while braking. Luckily, it seems that there was no problem on the manufacturer side.

However, to double secure drivers from crashing those crazy-quick cars, Tesla included in the V9 software version available for over-the-air-update, a new feature: Obstacle-Aware Acceleration.

When enabled, the feature limits acceleration if an obstacle is detected in front of the car (applies only while driving at low speeds).

Screenshots of the new feature were provided by Bonnie Norman, see below:

“…that would accelerate the car while breaking.”

Presumably braking was intended here, altho I suppose it’s possible… 😉


The aggravating instances of posters not identifying the differences between braking and breaking as well as lose and loose is tolerable. When an automobile related article misses the distinction between break and brake, I really start to wonder.

Correlation is NOT Causation.

Nope, not a GrammarNazi. The Nazis where not good people. More like #GrammarSurgeon

It would appear the owner has the option to turn the feature on or off, should be locked in ON.

I can see where having this feature on would interfere in racing situations. As you exit a turn with someone in front of you, you would need to be able to use all acceleration in order to maintain the gap.

Seems like the default should definitely be ON. I’m trying to think of any reason to turn it off. Maybe if that kept you from getting close to the back wall of the garage when you park?

It doesn’t stop entirely; it just slows acceleration — thus shouldn’t affect parking.

Definitely want to turn this off during a zombie apocalypse. Though I guess as long as you are going fast enough, it would override it.

That’s good

Good. This seems like something that should have fixed long ago.

And yeah, I know they worry about false-positives but that’s not much of a worry in a standing still or barely moving situation.

BTW, this worry about false positives (while driving at highway speed) just shows you how the technology really isn’t where it needs to be. I’m glad Tesla has pulled back on their “full autopilot” offering…it was always a pie-in-the-sky dream that it would be ready quickly.

It’s not really a “fix” (as if there was a problem), but rather idiot prevention feature.

I believe they actually had this feature in the X already (not toggleable) and false positives do cause a problem. There are certain places that have on ramps controlled by a stop sign with no space after stop sign to get up to speed (a concrete example is the ramp to cross the bay bridge from Treasure Island to San Francisco). That means you have to floor it from a stop to get the car up to speed. A false positive on this caused someone’s car to limit acceleration and cars in the back almost hitting them.

Damn , Tesla thwarts the actions of would be terrorists who hijack a Tesla in order to run down pedestrians. Said terrorists will be like Deadpool on a zamboni in Deadpool1.
+1 Tesla

Working at low speeds only, man.

The real question is, is it enabled by default?
