Hill Hold Function

[tezco]

Does this also disable creep for a second when you are stopped on level ground, or is there some degree of slope required to activate? (Note that I'm leaving the name out of this to avoid another side trip....)

I also noted that Hill Assist doesn't work in reverse but I'm okay with that. Perhaps in the future they can implement a control allowing the user to decide if it should work in reverse or not.

I know this was just clarified two posts above, but I want to specifically reply to your posts. It DOES work in reverse, but only if you are facing downhill. It basically keeps the car from going the opposite direction from what mode (drive or reverse) you are in due to a steep enough hill.

We have 5.9 installed on our car now and hill hold works great, but my wife noticed today that it doesn't seem to work in reverse. Any thoughts out there as to whether it would be beneficial or detrimental for the hill hold to work while in reverse?

The beneficial case would be when you are backing out of a parking space on a steep hill, the car won't roll down the hill when you move from the brake to the accelerator pedal. But the detrimental case under the same circumstances might be that you want gravity to roll you down the hill a bit while you are maneuvering into the space on the hill (basically once you are lined up in the spot, just using the brake to modulate your position, rather than having to go back and forth between the accelerator and brake to do so).

Curious as to what people might think about having hill hold engaged while in reverse.

I believe TM is calling it Hill Start Assist or some such.

Messing around with it today, on slight hills, the length of time which I held the brakes prior to releasing seemed to affect wether the hill assist came on or not.

I'm curious about the behavior of the hill assist. Specifically, it was suggested above that it would release immediately when the accelerator is pressed. Can someone who has 5.9 please report back? If it does not, I may delay installing 5.9 because 1 second is much too long to wait if it doesn't release on the accelerator press.
Also I've seen no reference to an on-off selection, any confirmation here either?

I have 5.9 and Hll Assist does release immediately and smoothly as soon as you press down on the go pedal. If you take your foot off the brake when Hill Assist is engaged and do not press the go pedal you have about one second before the brakes release.

There is no on/off function in the control settings for Hill Assist. It is always available. You can't turn it off. I'm fine with that. I think it works quite well.

Agreed, very happy with the feature and was a great addition.

That's a relief. It would be too embarrassing to fight the brake while somebody gets the jump at a light. If it works that well I don't care about an "off."

I agree. This new feature seems well implemented.

Thank you Tesla for this new feature!

Living in the Seattle area, I use this every single day. And on the super-steep downtown Seattle hills it's a godsend; no more large rollbacks!

Agreed, great added feature. Works well.

Had it for about 2 weeks now. Very pleased. There are one or two places on my (off-highway) commute that it engages. It behaves like a feature, not like something taking over. Excellent job Tesla!
