Brake Assist?

SwedeSpeed · Jul 12, 2013

I took the Riot to San Fransisco yesterday for a little cruise and noticed that it handled the hills quite well. I have the 2014 Sport 4x2 in Manual, and have been relatively disappointed in the torque of the engine as I am used to driving a little sportier sedans.

The riot however held-up really well and was able to handle the steep slopes no problem. I noticed when taking off up the hill at a standstill that it was not necessary to utilize the E-Brake to prevent rolling.

Is anyone aware if there is some sort of brake-assist mechanism that aides in ascending slopes from a stand-still?

It is definitley helpful!

Yes, Patriot comes standard (?) with hill assist programmed.

aroundincircles · Jul 12, 2013

Yes, I believe it does have a break assist on the manual.

The4WDPatriot · Jul 12, 2013

Yes, the manual Patriots have hill start assist standard.

I believe all patriots have a hill start assist program.

I'm pretty sure it's just the manual ones. But I could be wrong.

Not all manual Pats have HSA (mine doesn't; I barbecued my clutch a bit on those same SF hills). I believe it's available on everything except Sport 4x2 models.

I have the 2014 4x2!

for the 2014's its listed as a standard feature for a base model, so its probably something that was standard after 2010 or something...

That's what I was thinking.

I have a 2014 Pat Lat 6 SPD. Sticker says hill start assist. I stop on a hill, release brake to gas, and it drifts backwards. Is it not working properly?

AmericanPatriot · Dec 22, 2013

I have a 2012 4x2 sport with a manual and I have it as well. I think it's standard at least since the 2011 refresh.

Chrysler engineers program their vehicles to use the hill start assist when there is at least a 7% grade. Any less and it won't operate.

How do I know this?... My father is an electrical engineer at Chrysler and he works on ESP system for all RAMs, Challengers, 300s, and Chargers.

Won't work on more than 8% grade. How do you program this on/off without EVIC? I've read of a "wheel dance," but want to know if anyone has done this to a 2014 Pat. Thanks in advance.

Oh, the questions I have for your father...

O'DubhGhaill · Dec 23, 2013

Well, wheel dance does not have any effect on the HSA, no flashing of the esc malfunction indicator...

I'm glad someone brought this up. It doesn't matter how steep of a hill I'm on, it will roll backward when I let my foot off the brake. I have the 6 speed auto/FDI. Our Challenger with an automatic, it works perfectly and I can turn it on and off at the steering wheel buttons. It also doesn't matter how steep of a hill I seem to be on. The rear brakes bite, then you can feel them release as you roll away.
I was starting to think the "brake assist" was how it seems to hold itself back rolling DOWN a long hill. Am I the only guy who notices that?

Well, two terms are being used, one incorrectly to describe another.

Hill Start Assist is different than Brake Assist.

HSA is supposed to prevent roll back when the vehicle is over a certain angle but Brake Assist is a computer function that will apply brakes with full force if it detects a certain style of hard braking.

I *think* we all have Brake Assist. Basically studies show that under emergency braking drivers tend to hit the brake, lift and then hit them again. If the Patriot detects that pattern it will "help" your braking by applying them to max force for you.

I discovered this on a logging road covered in rip rap when a black bear stumbled out in front of me. It was pretty spectacular stopping I will say.

Find a empty parking lot and give it a shot, see how it works. You have to really stomp on your brake, lift for a nano second and get on them again....the vehicle will be stopping far out of proportion to what your leg force is saying.

Don't do it too often while testing, it really grinds down the rear pads in rear drum equipped units...ask me how I know. don't know what repeated use would do to 4 wheel disc brakes but it is supposedly an emergency only function, eh?

I don't believe my CVT, FWD Sport has Hill Start Assist so I can't comment on that. Maybe check with your dealer as to if it can be programmed in or out...maybe some of you got missed?

Window sticker on our 2014 pat lat 6spd FDI states HSA, but like 2LZ, it doesn't matter how steep, it still rolls back after braking on a steep hill. Looks like something for the dealer to check.

Does it roll back a bit and then tighten up or just keep on rolling?

If you were to not let out the clutch or give an auto some fuel.

I don't know why they would bother with Hill Assist in an automatic vehicle.

Darn, now I'm interested in this...I'm supposed to be wrapping oysters with bacon for tomorrow's breakfast.
