Disable down hill speed control? Hybrid co pilot 360

[hj630]

When I go downhill, there is a green icon on my dash and my truck will stay the same speed. I googled and it looks like a feature on co pilot 360 and says there is a button on center console to disable it. But I couldn’t find it. Anyone know how to disable it? Also iOS there a way to let the truck to remember the drive mode from last time?

Are you sure that's related to CP360? When I drove a hybrid Maverick for a day it seemed like that was for regenerating electricity with the electric unit. If that's the case why would you want to? You'd be kind of defeating the purpose of having a hybrid.

It only activate when going downhill. Regen is not 100% efficient. You’d want to preserve the momentum to get max efficiency. Plus I can brake to regen if it’s going too fast.
I found a link. Problem is, it activate regardless of my speed, unlike the website that says only activate <20mph

You just said it keeps you at the same speed. Pretty sure it's not using the brakes but the electric motor as a generator to keep the Maverick at the same speed. Therefore you're in regen mode. Not sure how you could do that more effectively than a computer.

I guess you don’t understand me. Regen say you have 90% eff. Then you use that energy and convert to kinetic energy, say motor and battery efficiency is 80%. Now you are at 72% eff. But if you don’t Regen and just let car accelerate, you have 100% kinetic energy

Not really and your use of percentages is odd and confusing. If the speed limit is 60 and by virtue of gravity the truck wants to accelerate on a downhill based on it's potential energy at the top you have kinetic energy based on whatever speed you're going. On the other hand, when your green light is lit and keeping you at 60mph on that downhill, you have the truck's potential energy being converted to the kinetic energy required to maintain that 60mph speed limit but the regen also stores some of that potential energy in the form of electricity stored in the battery. If you let the truck coast to whatever speed the hill dictates, you only have kinetic energy. If you use your brakes to slow the vehicle down to the speed limit, now you're converting kinetic energy into heat and some electricity via regen instead of the potential energy of electricity via pure regen.

button on center console to disable it.

Look for an option in the center-display Settings menu to enable or disable Hill Assist. Ford's Owners' Manuals need correction; can you find the Hill Assist icon in yours? I can't.

This doesn't sound right. In both C-Max and Escape, it only activates down hill at speed. I have seen Escape owners report problems due to bad calibration of the level sensing system; maybe yours is mis-calibrated and thinks it's all downhill?

On flat ground, there is off-throttle regen braking, but it's weak. Eco mode doubles it. Slippery mode halves it. None of this has the Hill Assist light on.

... your use of percentages is odd and confusing.

Not really. In linear systems, losses are cumulative. If regen braking is 90% efficient putting DC into the HVB, and the motors are 80% efficient turning HVB power into motion, the system efficiency is the product, 72% = (0.9 x 0.8)x100.

I look at it this way. More of a "use it or lose it" situation once gas is out of the tank.
