Curious why some do not use 1 pedal driving.

[Jseis]

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 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.

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?

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.

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.

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.

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

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

I might be missing something, but on my truck there is no option for 2 pedal driving. There is only an on/off toggle for one pedal driving. Also when I miscalculate the distance required to stop with one pedal driving and have to use a little brake, not often but, I loose a percentage of my regen. Did the 2024 get rid of the 2 pedal?

I've driven a BMW i3 for almost 10 years. It has regenerative braking that can be manually adjusted from mild to aggressive depending upon the driving mode: Comfort; ECO; and ECO Pro +. Throttle responsiveness and gradients also adjust. Both help increase range. We also have an Escape Hybrid, which has regenerative braking, although not adjustable or as aggressive. Coasting is easy once you understand how to modulate the accelerator.

Enabling 1-pedal driving on our Lightning was one of the first things I did.

I guess few with Lightnings have driven a manual transmission and understand how to downshift and use engine braking on downhill stretches. While it serves a different purpose, the concept is similar.

Well, if there exists a physical brake pedal then odds are the '24 still has 2PD as the default mode.*

Manual driver here, in fact my vehicle before my lighting was a 2021 Tacoma manual. I always slowed by downshifting.

I still don't like 1pd driving (for my use).

Turning 1pd drive OFF is the same as turning 2pd drive ON. 2pd drive is just NOT 1pd drive.

Lots of people talking about the fact that if you need more braking, you can always use the brake pedal when driving using just the 1 Pedal.

But I think that introduces delay and brain confusion in the driver that can increase the chances of under-braking when needed. The problem being that the driver gets accustomed to using just the accelerator to brake. Several people have even mentioned they never even touch the brake pedal. But what happens when the driver has let off the accelerator all the way and it turns out that is not enough braking? It may even lead to a moment of confusion to even realize that. Then they have to find the brake pedal which also takes time.

If the driver is accustomed to driving in 2 pedal mode, whenever braking, the driver already has their foot on the brake and they can modulate braking to the max that the vehicle is capable of without any further thinking about it.

In Teslas, the situation may be even made worse because in a Tesla, every time you touch the brake pedal its friction braking which cuts into your efficiency. Drivers train themselves to avoid using the brake pedal. So they may be hesitant to engage the brake pedal when they really should have started braking sooner and harder.
