What is Hill Hold Control

Hill hold control unlock ???? How to do

Hey guys,

please don't hit it, I've tormented the search umpteen times but still haven't found what I am looking for.

Would you be nice if you could provide me with a suitable link or answer ...

So:

How can I have the hill hold function activated at the FOH on my GTC (see signature)?

Is it just a software thing that can be unlocked via Tech 2 `?

Is that correct???

Thank you in advance and have a very Merry Christmas ...

Regards Alex ...: lol:: lol:: lol:

Of course, you can't find anything by searching, the function is also called Hill-Start-Assist or Hill-Start Assist.

And that is not a function that you just have to activate, you need at least a yaw rate sensor with cross-axis detection and of course ESP (if necessary with analog valves)

Hi BlackTM,

what kind of minimum configuration do you have to have (theoretically) to activate this feature?

greetings

I find the question much more interesting: How can you switch off the part?

The hill start assistant really gets on my nerves ... Can you deactivate it without FOH? Or are several other things connected with this?

@ globalwalker

The highest quality ESP should enable HSA, iirc is installed with DDS (and of course HSA).

I don't know to what extent which built-in yaw rate sensor delivers cross-axis values, but that can be found out by determining the part numbers and their use at the FOH.

Switching off the HSA is practically not possible without other failures because, as I said, it is in the ESP. The FOH may deactivate it.

Why is he getting on your nerves? It doesn't interfere with starting up, it just prevents it from rolling backwards. I think it's awesome, you don't need the handbrake all the time.

I also think that's nice and it not only prevents rolling back but also rolling down (e.g. when entering an underground car park);)

So I learned at the driving school that you can start with sensitivity on any incline without a handbrake and that (e) still works.

If I now want to start on a steep incline, I feel annoyed about the delay until the brake is released.

But if you always get off the brakes out of habit and then let the clutch come on, this may be a relief.

In my opinion, the hill start assist is only useful if the car is really full to the brim or when towing a trailer.

I also have the hill start assistant, it is very different for me when it goes, does it have anything to do with the incline?

Sometimes the car stops on the mountain and sometimes it rolls back, so until now that hasn't convinced me that much or I'm doing something wrong.

@ Picnicker83, I take from your statements you are still standing with your left foot on the brake while you let the clutch come on at the same time. Do you work at the circus ?;)

Seriously, I see no reason the handbrake Not to use, and that the driving school should have taught something like that, I don't know either. In any case, it goes more smoothly and guaranteed without rolling back than jumping from the brake to the clutch in a fraction of a second.

When I look at your Sig, this drive has a very benevolent clutch modulation (I also drove for 1 year). Whether this is beneficial for clutch wear is another matter.

Right foot on the brake, let the clutch come with the left until you have the "starting point", get off the brake (the car stops because of the clutch and can't roll) and hit the gas. It works great and has not caused excessive clutch wear on any of my cars.

If you know your clutch well, it should actually work well with every engine variant.

Maybe some will say: "I won't let a youngster explain to me how to drive", but that's how my driving instructor taught me and so far I've been doing it for almost seven years. Just give it a try ...

Hi,

every rotation rate sensor supplies lateral acceleration values, otherwise the ESP would not work, what you mean is a longitudinal acceleration sensor and not every rotation rate sensor has that.

If it is a Bosch sensor, there is 1 rotation rate sensor and 1 lateral acceleration sensor in the expansion stage. And then there is also the version which has a longitudinal acceleration sensor installed, with this expansion stage it is then possible to have a hill hold function.

If the 'small' sensor is installed, it is not possible to activate the HillHoll function!

You are absolutely right about that, of course right Foot on the brakes ... what a mistake on my part. Just forget about my contribution ..!: O

Do I get you wrong or do you really wait until the assistant releases the brake and only then do you drive off?
