Anyone planning HAC (Hill Assist) retrofit?
 

Hi Guys,

I found out about this technology when I went on my recent trip to Ireland. I rented a car (Ford Fiesta 2015/16 base model), and noticed that when I was on a hill, and when I release the brake while engaging the clutch, the car will not slide backwards, at first I thought it was my awesome clutching, but then I tested and realized it was HAC..

Now my question is, for a such economy car and it was able to have this feature, should it be easy to do a retrofit to our cars? I know the 2017s will have them, so wanted to see if anyone has already done/planning to to a HAC to prior 2017 models.. I am interested!

Thanks,

IIRC 2012 and up Camaro have that feature. I noticed when my coworker gave me a ride on a zL1

Not really.

I figure that anyone that needs that on a car, should have gotten a car with an automatic transmission.

;)

TBH I would still love that feature for when I'm stuck in traffic on a hill. But no, never thought of even looking for a retrofit.

Agreed. Zero interest.

Nope.

Nah. Using the handbrake works just as good.

I bet it is way more expensive to retrofit than you think. It's a cute feature but I wouldn't pay $ for it.

yea, just thought if a base fiesta has it, shouldn't be expensive to put one in. As much as i like the challenge, I just don't have the typical commute with that type of road conditions; but on the rare occasion that i end up in SF stuck on a hill in traffic, I don't like risking it.

I imagine it is like cruise control or something. Cheap and easy for the manufacturer to add a switch and program the ECU for it. But a bit more involved if you trying to DIY.

Funny enough the Genesis R Spec with no cruise control was the biggest turn off to me about that car

Naw no interest here! Use the ebrake lol

After all, it's one of things that should be tought to get licence, no?

It possible it could all be done with software using existing hardware


however I doubt anyone is going to spend the time to hack the ABS system and write code for engine and ABS/VSC control units, and it likely a legal minefield to alter ABS safety system code to get it to apply brake when 0 speed detected and clutch depressed, then release on throttle clutch released and speed above zero.

I remember reading about this feature on older subarus, they were a mechanical system and people would sometimes have the problem of the brakes not releasing when they should, or getting stuck.

One less thing to break, less complicated, etc. etc.
