Cruise Control vs One Pedal Drive?

[InTheHills]

On highway driving I always use Adaptive Cruise Control when I get a good auto controlled steering (UK hands-on required). That is only when camera picks up road marking both side of the lane. To slow down quicker after acceleration to pass, or approaching curve, or roundabout, I simply temporarily engage ‘L’ button on the selector switch. The amount of speed reduction depends on drive mode. It works a charm usually without using the brakes. L actually engages some regen similar to OPD.

Regarding using OPD, I highly suggest try doing the same drive same conditions using it and not using it, and compare your mls/kW!

Speaking from experience since April 2021 I’ve done this many many times over the past three years rate is consistently better without OPD on my AWD ER. in all sorts of driving.
Only occasionally I see a better rate with OPD around town with a lot of stopping starting over five or 6 miles.

The other problem with using OPD is especially on earlier models there is a consistent problem confirmed with scoring of the right rear brake disc.

One way to help this is to occasionally do hard breaking from 60 mph from N as advised by several Ford EV technicians.

It sounds like you know this system pretty well. Someone in this thread mentioned that the Mach e has "blended brakes" where the car uses the motors when I use the brake pedal. Do you have any info about that or know where I can find some? I goggled around a but but did not find anything.

Yes, it does. Regen until end of stop.

Not to my knowledge.

I have no idea. Both Mach-E and Lightning do.

Hopefully James III will see the thread, he seems to know his stuff!

I don't know what else you need. Blended braking on these vehicles is an established fact.

Hi it just from being an early adopter ? and 3 yrears+ of driving. yes breaking regens without OPD similar to soft hybrids. But this blended breaking especially applies when using adaptive cruise control, in maintaining distance from vehicle in front, and speed limit changes. In Active Mode you can see the break coach % regen captured from breaking on driver display. ??

I believe there is a misunderstanding here. While the car is in 1PD, having the Go pedal at its Origin signals to the car’s systems to slow down to a stop. For most people, having the car in Cruise Control also means having no contact with the Go pedal (it’s at its Origin point). This would make CC and 1PD in direct conflict with each other. The simplest thing for the engineers to do is disable 1PD while CC is active. ??

If you wish for the car to negatively accelerate in a quicker fashion, you will either need to apply the brake pedal or place the car in Unbridled mode. ??

Unless you have been in this areas you would not understand. The options are to sit behind someone doing 10 under for an hour or pass when legal, which very often means a very short passing zone followed by a curve. This is an example that is very close to me. It is 8+ miles in either direction to the next passing zone. So you come around the curve, get to a point where you can verify there is no oncoming traffic, have less than a 1/2 mile to pass and slow down for a serious curve. And of course the complicating factor is that flat landers will go 5-15 under in the curves but then haul ass in any straight section. It is maddening!!!

I recommend just chilling. You live where you do for your own reasons but you can't change the transportation infrastructure. Maybe you need to leave earlier to make an appointment, arrive at work, etc. We used to live in very rural Illinois farm country. We would be 'stuck' behind cultivators, school buses picking up or letting off kids, etc. that moved slow. I realized that I CHOSE to live there for the pace of life, the peace and quiet, etc. The farmers use those roads as part of their business and I needed to respect that. We adopted the attitude to relax, chill, wait until a SAFE opportunity to move around vehicles or after slow vehicles turned onto another road. Also, I never used cruise control unless the vehicle could maintain the speed for several miles. My simple strategy. Just too many adjustments during a short interval.
All the best. Drive safe.

My RAV4, which i liked, was pretty kludgy going from Adaptive CC to CC, parking brake (really kludgy) to using the brake and accelerator. I use CC, BlueCruise, 1Pedal, parking brake and also using the brake/accelerator when I want in Whisper mode. It transitions well, easily and predictably. I probably should try using the other two modes but have not.

With the exception of Tesla, pretty much every EV and hybrid uses a blended braking system. When you hit the brake pedal it attempts to use regenerative braking to satisfy the braking request and when that isn't enough, it starts engaging the friction brakes.

My Bolt EV had a blended system. As have all 3 hybrids from Toyota that I've owned (2005 Prius, 2012 Plug-in Prius, 2016 Highlander Hybrid). I only know of one automaker that doesn't do blended braking: Tesla.

Thanks for the life advise lol

Another adrenaline inducing scenario:
Say you set the cruise control for 75 and you're predominantly traveling in the middle lane. You come up on traffic that is traveling 60 to 65 and the safety system slows you down. You pass a bit of slow-lane traffic and notice your offramp is coming up in less than a quarter mile. You turn on your blinker to move right and exit while the car notices a wide-open lane and tries to accelerate with EV torque up to the preset cruise control speed right as you're trying to slow down and merge onto the exit ramp.
