One pedal braking

[pinhead]

I've driven an EV for 6 years now (Bolt then Mach-E). One pedal driving gives the best range, since friction breaking will not be used at all. Blended regenerative breaking on Mach-E will return some power to battery, but any friction breaking is lost. I use the break pedal only in emergencies.

Do most of the knowledgeable members use this? Does it have safety data suggesting it is as safe as regular braking? It is a little scary to me as sometimes it is hard not to brake more quickly than I meant to. Is it worth it?

I wonder why you think it's not as safe? Because you're having trouble getting used to it?

Just move your foot over to the brake at the times when you need to stop a little quicker....

I use it in "normal" mode because I get the best responsiveness. I prefer 2PD in whisper. You might want to try a few settings to see your preference.

Can we dispell this rumor that you're always in regen when using 1PD and not using the brake pedal?

It's false.

If you turn on the "power meter" that shows when you run out of regen and start using the physical brakes (requires a mod using ForeScan discusses elsewhere on this forum), you can absolutely see that limit with just easing up on the accelerator pedal in normal.

If I'm going 60mph++ on the freeway, and lift the accelerator completely, I absolutely see the limits of regen.

Are you saying that at times the brake pads are activated in 1PD?

All things being equal, you will use less brake pad material with 1PD driving.

I make sure I periodically use 2 PD driving so the brake pads and rotors get used.

Based on the number of posts here and elsewhere, our Mach-E's seem to have a pretty high rate of getting rear-ended. It happened to me, too.

And to me, but I was standing still and I know for sure that the brake lights are on in this situation.

I think that people behind us admire the beauty of our cars so much that they forget to slow down and stop

Not exactly true. If you modulate the brake pedal properly (due to blended braking), you engage the electric motors as generators And can avoid using the hydraulic brakes until the car reaches 4mph. This performs exactly like the regenerative braking in 1PD On the MME. You can see this at work on the power meter or in Car Scanner. It takes some practice, but it is eminently possible. ??

Come on. How may people do you think do, or even know how to, modulate the brake pedal properly?But even if you are the king of brake pedal modulation, to come to a complete stop you have to bring the pads in contact with the rotors. You don't have to do that with 1PD. Ergo, 1PD uses less brake pad material.

I exclusively drive in 2pd mode and the friction brakes aren't engaged until just before the car comes to a complete stop. As others have said, the power meter in the GT will show you when regen is happening. I still regularly have to shift car into neutral and use friction brakes to clean them off because they rarely get used in my day to day driving.

"...they rarely get used in my day to day driving." Rarely used? They get used every time you stop.

The friction brakes are only used to hold the car once the regen brakes bring it to a complete stop. The point is that in either 1pd or 2pd mode, the friction brakes are generally not used to actually stop the car. The regen brakes stop the car and the friction brakes kick in at the end to hold the car stopped at a stoplight, stop sign, etc.

This is untrue. 1PD applies the brakes in order to come to a complete stop. The regenerative braking is pretty much done at 4mph. 1PD lightly applies the brakes in order to stop and in order to hold. ?‍?

Thank you for the correction. However, I have looked extensively for any non-anecdotal reference that states 2PD preserves the brakes as well as or better than 1PD. If you have a cite for that proposition please post it.

Sorry for the confusion, I'm not saying that 2pd preserves the brakes more or less than 1pd, just that 2pd still uses the regen brakes most of the time.
