Downhill Assist Control

73

Now Implemented!

Description

Offer a downhill assist control for descending in icy conditions.  Some automakers call it Hill Decent Control (HDC).

Competitive/Pricing/Notes

In slippery/snowy conditions downhill assist control can stabilize a car when descending a steep slope. The all-wheel-drive option helps going uphill, but no additional improvement when descending! That’s why there are some roads in the alps that are closed in winter for cars without all-wheel-drive when going up – but for descending all cars are required to use snow chains.

Especially the heavier weight of cars like a Model S is a major disadvantage in conditions like steep slippery (downhill) slopes.

Moderator: Some Toyota SUVs offer Download Assist Control, but we didn’t see any other manufacturer offering it. This may mean it’s protected with patents.

Status

Tesla has advanced stability and traction control system, which works significantly better than ICE cars and is likely in the same league as ICE downhill assist systems.

Already implemented with TACC; regen is plenty strong enough EXCEPT when you have just filled the battery up completely so there is no place to put the generated juice.

On TACC, my speed on my P85D stays exactly on the setting up and down steep hills.

Regen is not strong enough to keep the car slow enough, e.g. 7 km/h

It doesn't do this?  I would think with regen engaged that it would take a heck of a hill to increase speed over TCC settings.  Okay, I don't have the car..but I ordered one.  Let me know!
