REGENERATIVE BRAKING

[MakinDoForNow]

I don't screw with "L", but I believe it also turns on the ICE to gain some compression slowing and waste fuel. At least I believe it does in my C-Max when I accidentally pull the shift lever too far.

I believe engine braking has fuel injection turned completely off. Some are claiming excellent mpg in low. Engine braking doesn't occur until HVB is over 70% unless computer determines for other reasons to use engine braking. Possibly when motors in HF35 heat up to some point?

As we discussed elsewhere, you need to be very aware when using Adaptive Cruise Control in a hybrid (dunno about EB). You can slow VERY fast with no brake light indication. I was on an 80MPH interstate and came upon a 60 MPH vehicle. I was on the furthest setting of ACC, so the regen brakes took it right down with that 20 MPH speed drop with NO brake light...much to the surprise of the vehicle following me (my wife, on hands-free phone with me).

Looks like if the government finds out there are too many rear end collisions in the Maverick there's going to be another recall.

My Maverick won't be here till September + shipping time. I have a question:

The brake lights don't come on when the truck slows itself with heavy regen?
If this is true, it's going to take some getting used to. We don't use the brake pedal in our Model Y and the brake lights DO come on during regen. It's a pretty good safety feature to ensure that people behind you can tell you are slowing.

I've heard that some EVs set up for one pedal driving only put the brake lights on when the driver lifts off completely - if the driver 'feathers' the pedal the lights do not come on.

Bolt EV (and probably others) measure actual deceleration. Negative 0.3 G of slowing and the brake lights come on.

So coasting downhill at less than 0.3 G or not slowing at all, no brake lamps.

I just drive in normal mode and use the brake and accelerator to control the regen (when going downhill, the gas will first reduce the regen before it starts actually using the car's motors). Around town trips (where I never end up on a road with a higher than 35 mph speed limit) I usually average about 50-60 mpg, so I've never felt the need to try and hypermile it better than that.

(Overall I average about 40 mpg, but I do a lot of highway driving)

I can say that in my Model 3 (Tesla) I can avoid regen brake lights to a point; if I keep the throttle engaged such that the vehicle speed change does not exceed whatever is the programmed threshold, yes - but it only works if you have a long distance in which to stop and can do that slower slowdown/stop

So no not just 'feathering' but if the car exceeds the velocity reduction threshold it comes on; some EVs are lame though like the Ionic 5 which supposedly can come to complete stop in 1-pedal mode and never light up any brake lamps. Bad in my book!

That makes sense.

My experience with the regen in hybrid Maverick is you let go of the gas pedal it slows down but not enough to use it as braking power. It's no difference than letting go of the gas pedal in EB Maverick

What he said, unless I’m in low then a bit quicker slow down but not equivalent to braking.

Mine slows 35 mph to 3 mph in about 9 seconds. Equivalent to how normal people brake approaching red lights or stop signs.

Not quite as quick as the Bolt EV regeneration, which is 70kw. The Maverick is half, 32kw. And hey, the G force is about half also.

Might be why so many Mavericks are getting rear ended. I agree that this would be a great safety enhancement. If regen braking is happening, the brake lights should come on!

Buddy of mine uses L a lot, going down winding curvy hills in this rural area. His mileage is in the 50s. No, it does not light the brake lights, nor does "gearing down" in a manual transmission vehicle. The brake pedal isn't being pushed.

Teslas light their brake lights when they go into regen. You don't have to touch the brake pedal at all. There's no reason Ford can't do the same.

It lights up the brake lights even if you just lift off the throttle slightly if your speed is dropping. I'm followed my wife home enough to know that's the case. She isn't very steady-speed...

Well, in Tesla's case they're hard into the one pedal driving cult and that you should almost never use the brake pedal. To the point that they don't even have blended (regen + friction) on the brake pedal; that activates the friction brakes only.

I wouldn't call it a cult, but yes, it's very nice and really easy after about a minute of driving to get how it works. It's adjustable, of course. A nice effect is that after 3 years, the brake pads and rotors still look like new.

I dunno, I've seen the vigorously heated debates Tesla Stans get into defending 'Why don't Teslas support blended braking' comes up. Personally I think the most ideal is the Hyundai/Kia approach where you can adjust the one-pedal'ness, have blended braking, and also have a separate paddle for regen-only braking.
