Preventing roll backs with creep off...

I prefer to drive with the creep off, and I have noticed the roll back issue.


This seems to work for me to stop it. Just one firm brake pedal push does it. Then I'm off the brake entirely with no roll back.



It seems to put a hold on the wheels as if the parking brake were on (but that light does not come on).

As long as you are on an incline hill, my understanding is this will work (creep on or off). Once you tap the accel, it will disengage the brake hold. Does not work on a decline as I have tried and it will not engage. On the slightest incline it does work for me.

Same here. It's actually kind of annoying that it doesn't automatically engage on slightly steeper hills. On very gentle uphill slopes the brake engages automatically when the car's velocity drops to 0. I don't understand why it can't do that on steeper hills.

It's also kind of frustrating that it doesn't work on a decline ... there is so little resistance in the drive train that the car starts rolling on an imperceptible downward slope.

Both of these would be software fixes. Will JLR have the attention to detail and the resources to address these small but noticeable issues?

I'm sure this has been answered elsewhere, just can't find it...

I drive on high-regen with creep off, however, my car does roll-back on any degree of incline, and no brakes are ever engaged until I tap the brakes. Is this a feature I need to turn on somewhere? I've heard people comment that there is a brake hold that happens automatically when the car starts rolling back ...

From the I-Pace manual:
BRAKE HOLD

Brake hold automatically activates when using the brakes to bring the vehicle to a stop on an incline. The feature operates in Drive (D) and Reverse (R), holding the brakes on until the accelerator pedal is applied. As the accelerator pedal is applied, the system automatically releases the brakes for a smooth pull away.

Thanks. I also read that, I guess what I was missing (and hoping) is that when the car comes to a stop through high-regen, NOT brakes, that it would apply the brake hold before starting to roll back. Apparently, there is no way to set that up, so you have to kind of "tap" the brakes, not super hard, but hard enough, you can then let go and brake hold will catch on (I was out playing with this on my last drive, and that's what I got) Good enough I guess!

Yes, it does take a hardish tap on the brake to engage. It is the same as my Tesla Model S. It still baffles me why they would design this to work only on an INCLINE and not the DECLINE (Tesla works in both directions). What could the reasoning be behind this?
