No regenerative braking!!!!!!!

[roitan]

As as scout and tesla model y owner I sold shortly after , this was what i hated most! Or atleast be able to turn it off. I control the car and what features it has, not the other way around!!

Fair that it takes getting used to and the ability to adjust it is available on most EVs. It seems though that most people seem to really like it once they get used to it.

We have a Rivian R1S and the regenerative braking took some getting use to, but overall its great. I would ask that the Scout have the ability to turn it off. It's our first winter with the Rivian. The roads in Michigan were quite icy the other day and I took my foot of the accelerator as I would in my 4Runner. My intention wasn't to brake, but to coast through the icy stretch. The regenerative brakes nearly put me in the ditch. I understand now that there is a way to turn them down but not off. Please offer an option for turning regenerative braking off.

3 things I would consider, since you're in a Rivian:

1. Use SNOW MODE in those conditions
2. If you are not in snow mode & have normal settings and want to cruise through ice, do not take your foot all the way off the accelerator
3. Dedicated snows in winter make a tremendous difference in traction (in any truck - ICE or EV)

Thank you. Yes, the Rivian was in SNOW Mode. The tires are great, so its more of an issue of regenerative braking too hard. My coworker has the R1S and spun his out the same day because of the braking. He's the one that passed along the tip of dialing the regenerative braking all the way down. I wish we could just turn it off in bad weather.

Right, but SNOW mode automatically sets REGEN to "LOW" and softens throttle response...

Not sure what your co-worker was saying, because the truck would have already been in the lowest Regen setting:

here for regen braking. If it wasn’t being included, I’d have serious reservations about the design and engineering.

#2 and #3 are fundamental to good driving any vehicle on ice. Snow tires are essential. Using the accelerator as a modulator provides far more control with an electric motor. But it doesn't matter what the power source is, suddenly changing the power to the wheels will open up the possibility of loss of control on ice. Fortunately EVs can recover from that much, much more quickly with >1kHz wheel torque modulation through the electrical traction control and ABS.

I won't buy a vehicle without regen and I won't buy a vehicle without 1PD.

Personally, I like regenerative braking, but having the option to reduce the force would be great for those who don't like it or haven't had time to adjust to driving with one pedal. Not sure how difficult it would be for Scout to implement.

Hopefully it'll be easy to add as a option in the drive settings or something with a low, medium and high setting or something like that. I'm used to full regen all the time so that's what I'd be having mine set on. I'm hoping there's not any regen paddles that some vehicles have. Just controlling it through the accelerator (gas) pedal is good for me.

Interesting. I selected SNOW mode at lunch and Brake Regen is set to High. Should the default be low?

I would agree. On a sports sedan or sporty car I love the paddle shifters but on a truck/suv not as critical. That said our Honda pilot has them and I instinctively find myself using them in some situations so if you are used to them it’s nice but certainly not a necessity

Please pardon me for sticking my nose in and asking dumb questions, but I wanted to see if what I’m thinking of as regenerative braking from my Prius experience is the same as the EV experience, just kind of more customizable?

In my experience, I’m pretty much always going to charge the battery from braking (or charge it from the engine, but let’s just keep that out of the equation because that’s a Toyota thing), and sometimes from coasting depending on the laws of physics (speed, slope, drag, whatever else factors in). Is that the agreed-upon definition of regenerative braking? Am I going to get into an EV and be completely thrown off from by it based on my Prius experiences?

If I’m on the same page as everyone else, I guess my next question is why regenerative braking is bad? Is it just the weirdness of fly-by-wire brakes or the fact that electric engines don’t do that whole gear-shifting thing (thus we have stuff like “snow” modes, or on my car there’s a “brake” mode when you know you’ll be going downhill for a bit)?

I read through this thread, but it felt like I was watching the third part of a movie series without being around for parts one and two and missed some important plot development.

I drove a Prius since 2002 until about 2018. The differences will be negligible between driving the Prius in "B" mode and driving an EV in 1PD. When driving an EV with 1PD off, you'll be coasting in a similar way to how the Prius would coast when you lifted off the accelerator in normal drive mode. It still uses regen, it's just not as aggressive.

To me, the difference is basically 1PD is like using a clutch on a manual shift transmission and 1PD off is like driving an automatic.

There's nothing bad about regenerative braking. It's bad not to have regenerative braking. People just don't understand how it works so take the worst thing they read or experience about it (usually once) and apply that to all of it.

That was helpful. My accord has some regen but it’s from direct braking only. Appreciate the knowledge

Yes, tap the lower right circle / arrow icon that you can see in your picture (under SNOW MODE) to refresh your settings for that drive mode, and you will then see REGEN is set to LOW.

Oh, excellent! Thank you for confirming. That’s a relief. I was worried that this was wildly different from my expectations and it doesn’t sound like it is. I don’t think I’ve ever made use of B mode, honestly. I live adjacent to a steep hill (it’s narrow and two-way, but it does takes me to the road I most use to get to points south of me… ), but I’m usually driving up it, not down. Hmm…

Call me crazy but I regulate m driving 90% of the time with ICE just using the gas pedal unless it’s heavy stop and go traffic. I avoid brakes as much as possible to reduce wear on my brake pads and rotors. Do most people use their brakes constantly? I’m a mix of rural and city driving so I get braking in the city but even rural driving I’ll use my paddle shifters rather than brakes I just don’t get the benefit of regen.
Maybe I’m overthinking this process.
As for paddles-if m driving long distance than yeah-my hands are on the wheel as @Bodie mentioned but in heavier traffic I naturally keep two handed on the wheel. Prior to my hybrid Honda I had higher performance cars so I tended to drive very spiritedly so two hands on wheel was about safety and control

Same here, I use my brakes as little as possible. So in a way I’m driving “one pedal” as often as possible until I need to decelerate quicker or come to a stop even though I’m not in an EV. It’s just how I drive. I find the “gas or brake only” style of driving very inefficient and even to the point of being annoying - I can’t really be a good passenger with people who drive that way. Not surprisingly, I get much better gas mileage than other people I talk to with the same vehicle. I don’t have regen but I’m also not constantly on and off the accelerator or using my brakes to lose (waste) momentum. I feather the accelerator and coast to my advantage a lot.

Perhaps one pedal driving wouldn’t be an enormous shift for me. However, I would still like everyone to have options to configure the experience to their liking.

I used to have a Camry Hybrid. The regen in it was about how an EV set in its low to medium regen settings feel. But, I utilize max regen in EVs to facilitate one pedal driving. After getting used to it I find it much smoother and easy to operate and modulate.

Thanks, yes, I should have maybe said a bit more.

With many EVs one can change the drive profile that basically adjusts what the accelerator position means. Usually 0% and 100% always mean the same thing, but manufacturers can do very different things between those end members, and they can also look at the speed at which the accelerator is moved between positions to change driving behavior.

With aggressive 1PD, lifting off on the accelerator engages the regenerative braking almost as if one were moving their foot over to press on the brake pedal, while with gentle 1PD, lifting off the accelerator can engage the regenerative braking much less aggressively. Lifting quickly might have one response while taking one's time lifting may create a different response. The manufacturer will usually program several profiles for this and the driver will choose the one they prefer.

Overall, everyone I know who has an EV has played with the 1PD options and chosen the one they prefer. I seriously doubt Scout will program only one accelerator profile, especially given that they're marketing this as an off-road vehicle, which will necessitate a different profile from highway driving.

I agree, not to mentioned the free energy one gets to recoup from regen. I keep mine on HIgh. I do have the option to turn it off on EV.

EVs should have a configurable system to pick their preference. But note that turning turning it from high to fully off really won't make that much difference in energy recovery.

If you turn off Accelerator pedal regen, you will still get regen as you gently apply the brakes. So you can just set Accelerator pedal regen to the level you prefer and you still get regen on stops.

It makes no difference to energy recovered if it's triggered by the brake pedal or by the Accelerator pedal.

On top of that at highway speed, it's generally more efficient to coast:
