Winter/snow driving & one pedal mode

[Maquis]

If you lose traction while letting off the accelerator pedal in 1PD, ABS kicks in just as it would in 2PD.

You should definitely practice more so you gain confidence in the truck and your ability to tell it what to do. Any time you are driving in slick conditions you should be smooth and drive slow. Never "hit the brakes hard" as you could disrupt the balance of the vehicle which might induce an unnecessary slide.

Exactly!
What folks fail to acknowledge is that the regen is exactly the same whether in 1PD or not. The difference is the method of user input. Over years of driving, when slippery conditions are encountered, the first reaction is to completely let off the “go” pedal. Doing so in 1PD can result in over-braking for the conditions. It’s no different than stepping on the brake pedal too hard.

I do not trust 1PD if it’s super slick. Letting off the accelerator in very slick conditions has led to me almost going sideways because the regen is too aggressive in slowing you down. It was very similar to when I downshifted (in an old Camry) too aggressively trying to slow down going down a slick hill—lost traction for a scary second there too before I went back up a gear.

I didn’t leave 1PD turned on so I could test different things, but for people who do use 1PD in slick-as-hell conditions—do I hit the brakes hard enough so that antilock kicks in? Or do I need to feather the gas pedal ever so slightly to regain traction, but still get it to regen? I don’t think either is a great solution, but I’d like to do some more testing when I can find a safe place with these conditions.

Bottom line, as soon as slipping is detected "regen" stops and the mechanical brakes and ABS take over. Your slipping and sliding is from trying to slow too quickly, not from regen.
