One pedal drive - Jerk motion

[Cjpayne]

I think it is wise for you to use Whisper until you get to the "feathering". Then progress to Unbridled. OPD is one of my most favorite features over ICE. I love it! I am confident it will get better for you over time.

Gotcha. I will try this and see the behavior. Thank You!

Agree with the others, don't lift your foot off the accelerator abruptly. That isn't really the intended use and will result in wasted energy. Ease up when you want to slow down and continue gradually as long as it is safe to do so. In an emergency, you can always use the regular brake pedal.

You might try checking to see if auto hold is enabled and if so, try disabling if you continue to have issues. 1PD was very rough with auto hold enabled in my car. In fact, that was the first thing I thought of when I read the title of your post.

I really don't like 1PD in this car at all. Love it in the Wrangler and Polestar 2 but the Mach-E does not work well for me. I have tried and tried to get used to it but it just feels very poorly executed for me. Many like it though. You might be part of that group.

If not, try disabling 1PD and use L. That is a nice compromise for some of us. I drive in D on the highway and use L frequently on surface streets. Works okay for me. Good luck!

I lift my my foot off the pedal completely and quickly when I want max braking without pressing the brake pedal and don’t experience anything I’d call a “jerk”.
I wonder if your auto hold is engaging in prematurely? You might try turning it off and see if it makes a difference.

You make a good point with auto-hold. I will try that too. Thank You!

I will try doing just that. Thank you!

It shouldn’t make a difference. 1PD is doing the same thing as auto hold once it engages the brakes.
I only notice a slight jerk on inclines if I didn’t feather the pedal.

I know it shouldn’t. I’m suggesting to him that perhaps there’s a problem with how it’s functioning. Turning it off should eliminate or confirm that possibility.

I'm surprised more folks haven't come forward to voice their opinion re: the "lurch" at the end when you take your foot off the accelerator pedal in 1-PD [or push the brake pedal] to come to a complete stop. To me, it is the most annoying aspect of driving the MachE. I do have Auto Hold enabled as well, but I should not have to keep the accelerator pressed ever so slightly to avoid this jarring effect (not unlke the response when engaging the clutch too early in a stick-shift). Maybe an OTA can/will fix it, but it does diminish an otherwise pleasing driving experience.

Has anyone observed that when One pedal drive is engaged and the vehicle is about to come to complete stop, there is a jerk that rocks the vehicle front and back ?

Not I. I find the one-pedal drive stops to be remarkably smooth, better than a human driver (present company excepted, of course).

My passengers are uniformly impressed - they find it difficult to believe the car stops so smoothly all by itself.

Agree. My experience is pretty much the same. It's much improved with auto hold turned off but the lurch is still there. Barely noticeable when slowing to a stop from a forward motion but very disturbing in reverse. Jarring actually. With practice it can be minimized for sure but it's really just one of the many reasons why I don't use 1PD in this car. The foot fatigue is what is most off putting to me. My foot and calf get tired after 50 or 60 miles and then I have to switch it off for the remainder of my day. So, I just stick with regular D and use L from time to time and I am less exhausted at the end of my day.

unfortunately this is all due to Ford Poor tuning of the transition between regenerative braking and mechanical brakes. Feathering the pedal is a poor substitute.

With tesla, you can let go of the GO pedal and it will come to a smooth, non jerking stop every time. No so with the MME. The good news is that FORD should be able to tune this in software. Hope there are updates in the future.

I love 1 PD in the tesla, but detest it so much in the MME that I turned it off.

My Mom told me decades ago to stop trying jerk-off

That is one point of view and makes sense from a driver's perspective.
I have strong reason to believe there are other factors at play here. Tesla's method can be considered irresponsible and reckless in regards to the thermal and mechanical stresses placed on the system. There are other EV manufacturers that don't even offer 1PD for those very reasons.
The Ford system is a good compromise. You get 1PD for those that like it but the software doesn't allow the driver to abuse the system. Dropping throttle at speed is very hard on the system. There are EVs out there that allow more kW via regen than via DCFC! That is kinda crazy in my opinion.

But it’s not turning anything off is what I’m saying, 1PD holds the brakes... Only difference might be not holding when in neutral.

Excuse my ignorance, but why would this be irresponsible? I'm assuming that after having sold over 1mil Evs, all with aggressive regen, I don't hear any reports on problems with battery overheating from regen. With Tesla, they do limit regen on cold battery or if the battery is near 100%.

I think the problem with FORD is not the amount of regen, but rather the transition point between regen and mechanical braking.
