One Pedal, Again!

Exactly!

So lets address that.

1. There is no DRAG effect using 1pd driving. You can possibly slow down, by regenrative braking, in the exact same way using the brake pedal provides. Yes, if you let off the accelerator you slow down, which is different than in 2pd driving, but that is literally the POINT of 1pd driving so using that as a "difference" shows a lack of understanding of the topic.

2. Yes, there is a coasting period. That is quite obvious and I really hope you don't need that explained to you. Again, that is the ENTIRE point of 1pd driving. Obviously letting off the accelerator in 2pd driving coasts, no crap. We are WELL beyond that. If that is your argument then you really need to catch up to the points here.

3. Yes, the vehicle slows down the same way. I don't understand how you are lost here. If you release the accelerator a set amount regenerative braking slows the vehicle a set amount, in exactly the same way as if you press the brake pedal a set amount. The electrical and mechanical systems work exactly the same, where the drive makes their inputs is what changes, but that does NOT change how the systems work. And energy coach identifies if you brake MORE than regen can provide, which 1pd drive wont' do automatically but you can do with the brake pedal, however in both cases if you wanted to slow at that rate you would need to apply the brake pedal to a set level that engaged the mechanical brakes. Provided you do not exceed the ability of regen to slow the truck you get exactly the same energy back.

4. Again, the vehicle response to drive inputs. If that input is releasing the accelerator a set amount or pressing the brake pedal a set amount the vehicle responds the same way. There is no one or the other in charge depending on what mode is used, they BOTH use the driver inputs.

5. Where do you get gravity here? Do you only parallel park backing downhill in reverse. OUtside of 1pd drive the computer is automatically applying throttle to move the truck, it isn't "coasting", its being driven. That is a computer function designed to mimmic an automatic transmission. If that wasn't there the truck would be like a manual vehicle in neutral.

The rest of that is just trying to make an argument by claiming "I'm so smart", if your counterpoint is just to claim you are smarter than everyone and everybody else is just dumb....Bottom line I think you feel you are so far ahead of everyone they can't keep up, in truth you seem to be way behind the conversation, which is causing the issue. I mean, your not grasping that 1pd drive isn't "drag", its regenerative braking, the same regenerative braking that pushing the brake pedal provides. Or that how much you release the accelerator is the exact same thing as how much you push the brake pedal. So maybe stow the condescending garbage and provide real inputs.

You’re losing the plot.

You claimed that there is no material difference between 1 and 2 pedal driving.

Then proved that there is.

The question asked was why are people not using 1pd, the reason you are now giving “regenerative braking” is what I said when I called in “drag”, in order to simply and describe the feeling users experience.

I’m not smarter than anyone, I’m just answering the questions.

With 1 pedal driving, you no longer have the free coast aspect of driving, which makes the driving experience different.

This is the core of the answer.

Stop trying to make this a typical internet back and forth and simply accept the facts, it’s really not that big of a deal.

I believe nearly every EV does it this way. Bolt, rivian, Tesla, they all do it this way.

I highly doubt any evidence manufacture is going to just throw away massive amounts of "free" energy

I am pretty sure all Teslas to date only do regen from one pedal driving and their brake pedals only activate the friction brakes.

Not sure about other brands, but Rivian also did not have any regen from the brake pedal that I could figure out during a test drive.

Tesla has done regen on the brake pedal only in the last few years - Originally it was only in 1PD but they have evolved the system to include regen on 2PD. Not all Teslas have this. Some Tesla owners say it isn't as good since the brakes don't feel as solid. With Ford, most can't even tell it is doing regen with 2PD on braking.

I think you are correct with Rivian. I believe is all 1PD regen and you can't turn it off. I don't think they have a 2PD like Ford - It is a deal breaker for some.

Porche uses regen on 2PD similar to Ford's 2PD. To my knowledge, they don't offer 1PD.

Chevy started in 2011 with 1PD regen on the Volt and has progressed through a number of iterations including regen paddles on the steering wheel. Current EVs like the Silverado EV give you a choice of 1PD regen or paddles but to my knowledge it isn't used on the brake pedal.

I believe Hyundai only does regen on 1PD (i-Pedal) mode. I'm not sure if it can be turned off, the level can be adjusted.

I quite like the simplicity of 1PD and 2PD from Ford. While it would be nice to have a setting to adjust the regen strength in 1PD, we know we can increase by using Sport mode. 2PD works as it should leaving regen complexities to the technology in the truck with no impact to driver style coming from ICE F150.

1PD or 2PD is simply a preference.

Digging into this some more, there is some confusion about Tesla, because they have something they added in the past couple of years called "Blended Braking", but its actually kind of the reverse - it applies the friction brakes when you let off the accelerator if needed to make sure you always slow down the same predictable amount when regen is not available.

Chevy Bolt (and the old Volt) is reported to have good blended braking from the brake pedal.

There are also many hybrids that only support 2-pedal driving. The Prius hybrid seems to get mixed reviews that the transition from regen to friction brakes is not smooth.

Fused ankle prevents the 1 pedal driving. I found that the constant pedal adjustment cramped up the leg as I cannot just adjust the ankle. Adaptative cruise control is now a must have and Blue Cruise is amazing!

I started off with 1PD and switched it off after it engaged the break on snow and skidded a bit. With 2PD, I'm actually coasting when able, using regen to slow, and the big improvement...not flashing my brake lights every time I take my foot off the gas. not sure if I'll go back when the roads clear.

Our 24 year-old Sears garden tractor has a brake pedal, a power pedal and an infinitely variable forward reverse shifter. Battery powered ignition too! I can drive circles around the Lightning. I probably get many hundreds of miles per charge unless I forget to disconnect the battery. Vampire drain or my neighbors stealing electrons. I’ll get 3-4 years out of a battery. Electric clutch. No shroud so it’ll break a window at 50 yards. Narrow track. A hoot to mow with. The Lightning pouts. Probably wants a mower too. It could tow a gang 8, probably at 110 mph too. Gives new meaning to 40 acres and a Ford. But I‘ve a ‘41 9N for the back 40. It’s 3 pedal.

I don’t believe the Ford 1PD mode ever engages the friction brakes at all. But the regen is aggressive so it might feel that way on ice. We are either going to have to feather the throttle in 1PD or the brake in 2PD. Pick your poison.
I just wish it was easier to switch between them, like our i4.

Has anyone tried switching drive modes via voice command?

On my 2015 Tesla model S the one pedal will not completely stop the car. It slows it down to a couple of mph and then I have to apply the brake. On my EV6 the one pedal, they call it I-pedal (eye pedal) one pedal must be a registered trade mark, anyhow it works the best of all. The brake light does not automatically come on as soon as you let off the pedal. They have figured out an algorithm that only turns on when you are actually stopping. The regen is not quite as aggressive as the F150.

The Lightning 1pd drive will use the mechanical brakes instead of regen if it detects the tires slipping.

Traction control will definitely use the brakes when it feels slippage in both 1PD and 2PD.

 

[CavRider]

The Lightning 1pd drive will use the mechanical brakes instead of regen if it detects the tires slipping. I monitored the brake line pressure during our last snowstorm and when in 1pd drive and aggressively releasing the throttle you could see the brake line pressure spiking the instant the wheels started slipping. I have done similar tests in dry weather and 1pd drive only used regen.

Ford did a remarkable job keeping the feel of the truck consistent regardless of which method is slowing the vehicle.

OK good info, thanks. I was wondering if they had incorporated ABS in some way but alas, here in central Minnesota we do not have typical winters anymore so I have been challenged to find a low traction surface on which to test.

I'm envious . . would die for a lil JD 20something, just don't have the property for it . .

I would try one pedal drive in a heartbeat if I didn't also regularly drive a gasser. I think it would be difficult going back and forth from 1 vehicle to the other

I have seen in some threads that some don't use the 1 pedal driving and I wonder why. I took a 60 mile drive yesterday and only had to use my breaks twice. At the rate I will likely never have to do a brake job. Plus a little energy recovered.

Whether it's ice or EV you still slam on your breaks either way if you have to stop fast their both the same in that since I can't see not taking advantage of one of the best attributes of an EV for several reasons for
