New Feature Request: full regenerative breaking when pressing the break slightly

[eprosenx]

This is a tough one for me.

I do think Tesla's implementation is brilliant (extremely smooth), but I do wish I could just let off the accelerator pedal and just "coast" without regen. Sometimes you just want to coast...

But then other times I want to engage max regen but not use the brakes.

So I really made heavy use of the regen handle in my Gen 2 Prius. When going down the West Hills (my commute route into Portland) I would engage regen mode and the prius would do mad regen braking. Normally when letting off the accelerator it would do a little regen, but not full regen (the handle gave you full regen).

What was interesting was that once I made it most of the way down the hill, the puny prius battery would be full and it could no longer regen brake. But they wanted to keep the user experience consistent and so it would shove the CVT ratio all the way over so the ICE was rotating rapidly and providing some amount of compression braking. It was just funny to me (the noise kind of freaked out my wife since it was unexpected).

So yeah, if Tesla is listening: I want a third control. Not just the accelerator and the brake, but also perhaps a hand control to engage regen.

how about just slowly releasing the accelerator when you want slight "braking"

The Bolt's 1 pedal driving setup is superior to any other regen braking setup out there IMO (admittedly a bit biased). You can get max regen at any time simply by pressing the regen paddle down, and it will bring the Bolt to a full stop without your foot being anywhere near the brake pedal. Pressing the regen paddle down while in "L" drive mode (heavier regen setting), regen is so strong that I still sometimes have to press the accelerator down to creep up to the stoplight. I can literally go days at a time without ever touching the brake pedal, driving local roads as well as the highway.

I heard/read that Nissan e-pedal also provides true one pedal driving.

Maybe TACC with AP3 has the power to full stop you without friction brakes?

No.
My understanding is that the regen cutting out under about 5mph is due to the type of electric motor.
If Tesla changed to permanent magnet motors, you could have regen all the way to 0 mph. I don't think it is worth the cost.

Yes, I was of the opinion that the Bolt’s was the best blended implementation until I drove an ‘18 Leaf. E-pedal is really slick and doesn’t require futzing with any paddles or L mode or anything. Absolutely one-pedal driving outside of extreme edge cases.

That said after living with Toyota, GM, Kia, and Nissan’s blended braking systems I’ve come to really like Tesla’s setup. I used to think it was just a cost cutting thing but it’s nice to gave actual brake feel again and efficiency hasn’t suffered.

.... huh?

The Model 3 has a permanent magnet motor in the rear of every car.

i picture everyone getting car sick...

so you're saying if you press on the brakes just ever so slightly, it will slam it down a lot just to try and regen? this can't be good for stop and go traffic

It isn't a traditional PM motor. It is called a Hybrid Switched Reluctance motor which uses, as I understand it, less mass of permanent magnets. It also doesn't have regen all the way to 0mph

Yes, but it blends in friction brakes. I like being able to 100% not use the friction brakes unless absolutely necessary.

Yep... No bended braking in the Bolts.

It would be nice if it blended in friction braking when regen is reduced to keep the experience consistent at least. I was a bit surprised at 100% for a road trip when there was no regen at all. Luckily I remembered quickly why that was and hit the brakes.

Blended braking discussions seem to come up frequently, people not see other threads or ?

Personally I like non-blended braking as it seems much more obvious to me what will happen, even in the cases where regen is less or disabled due to battery SOC or temp etc

I hope Tesla never complicates the braking by making it a blended system - I know not everyone agrees.. Once you master the way it works though, it is my belief you would come to love it as it is..
