Automatic Hold When Stopped (Implemented)

Now Implemented!


When the vehicle is in Drive and speedometer reading is zero, a brake is applied to “Hold” the car at zero until you press the accelerator, whereupon the brake is released. This would enhance the “Hill Start Assist” feature which only applies the brake for one second and only when you are on an uphill incline (in Drive — downhill incline in Reverse). Why not allow you to take the foot on the brake immediately and have the hold apply until you press the accelerator?


This is a feature already available on the Lexus LS460 since 2007. It has a steering wheel button that must pressed to start the feature. It is always disabled when first starting the car.

It may not be possible to add it as a software only feature, if the parking brake is required to activate/release quickly (Lexus uses the parking brake for this feature). The Tesla parking brakes may not switch state fast enough. Hill hold works by using the motor to hold the position, and it may quickly overheat while using a huge amount of energy to maintain the braking function for more than a few seconds.


Now available with version 7.0 software.

My desired function would be the exact same as the Mercedes Benz HOLD function:

- creep mode is active

- break down to zero

- push the break pedal harder to activate HOLD function (otherwise creep mode is active)

- release with accelarator pedal


Brake hold is one of my favorite features on my Lexus LS460.  Once you get used to it, it is annoying to not have it.
Status indicates this is now available with version 7.0 software. But I'm at version 9.0 and cannot use the harder push on the brake to lock them until the accelerator is pushed. Does this only apply to certain generations of vehicles? Mine is 2013.
If this has been implemented, how does it work?  I’d love to enable it.
Are you sure this has been implemented? I don’t seem to have it on my 2013 S 85, or if I do I’ve no idea how to enable it.  The car does keep the brake on for a couple of seconds at a standstill, but it's not a complete solution - brake should stay on until accelerator pressed.
This was definitely implemented in my most recent software update as of Nov 2019 for my Model S 2019 vehicle.    Regen is improved, and it now also includes a smooth transition to friction brakes as it nears full stop.  This holds the vehicle in a full stop without backsliding, even on slopes, without ever having applied the brake pedal.   We now essentially have one-pedal driving, (except for hard braking in emergencies).
