I have a Gen2 and feel like the engine tries really hard to crawl / creep when I am going very slow or slowly starting. Honestly, I'd like to turn it off. I come from a stick shift vehicle so this creeping is not natural to me. That said, I hope that if I have my foot firmly on the brake or perhaps if I have been braking for 2 seconds that the engine wouldn't keep trying to push because that is a huge waste of energy IMO. Are there other things that this feature integrates with like hill-hold or something else? Is there a good reason Chevy does not allow us to turn it off? I wouldn't feel so turned off by it if I knew that it served ulterior purposes.

It turns off when you are stopped with your foot on the brake pedal, so no big waste of energy. Many people find it helpful when parking so they can do it with one pedal. Also safer to have that foot covering the brake instead of adding power.

Makes sense @Barry. Thanks

I find it somewhat humorous that EV manufacturers artificially induce "creep," because people are so used to it, when it's an unintentional artifact of the implementation of the automatic transmission's hydrostatic clutch.

This!!! The creep/crawl is all artificial. The electric motor isn't really pushing gains your brakes like and automatic transmission. But if you want to stop at a light and really be in neutral like a stick sift out of gear, then justill put the car into N

Personally I like CREEP but I wonder what prevents GM from implementing a system like Tesla - switchable?

 

[Norton]

Can you imagine parallel parking a Tesla or an i3 with creep turned off?

A friend of mine is the one who implemented it, back in Roadster days. He once told me that they didn't have it at first. But got so many questions/complaints that he added the feature. User-selectable of course.

I'm sure some GM design engineer could set some value to zero and spit new software into some system and crawl would be gone, but we don't have access to those tools.

I've always wondered with all the complex gearing between the ICE and 2 electric motors/generators why we can't have some cvt to the drive wheels to adjust the fixed 7:1 gear ratio. Certainly cruising down the highway could be made more efficient with gearing.

'Tis the beauty of over the air updates. Get feedback from customers, add a menu option or a new screen, push it out in the next update.

Gen 2 does some of this.

I drive in city traffic 99% of the time. Only once or twice a month I take a highway to another city. But it does tire me to keep my foot on the brake to hold my Equinox still in city traffic. I do shift it into "N" at stoplights and the Equinox is heavy enough to stay still. If there is a slight incline while in "N", I step on the brake lightly to hold it, but I am not fighting against the engine.

So I would love to remove the "creep" because it prevents me from shifting that much, and I rarely need thet "creep" to move in traffic. In real life stop and go traffic, you have to move faster than a "creep" when the vehicle in front moves because the car in the side lane will accelerate quicker and take up your space. Since I have to accelerate to keep up, I don't use or need "creep" at all.

If the Bolt EV doesn't have a switchable "creep", I will try to do it myself.

 

[OneMatt]

The Bolt is supposed to have true 1-foot driving, so no creep at all (user selectable).

That said, this is why they have creep:

Driver says the car did it all by itsrlf, but Tesla engineers found driver input on the pedal. Looks like creep off, with insane/Ludicrous Mode on. Accidentally hit the throttle instead of the brake and zoom zoom boom!

Creep using brake only would prevent this.
Yah yah you are expert and would never do this, but average driver is far from expert.

 

[2017voltowner]

That video says it all. See, with a manual, you generally have your foot depressing the clutch pedal as you park. In fact, the entire parking muscle memory is totally different. It would have been very unlikely for a person to accidentally push the gas and plow like that, maybe some smoked clutch but that is ok.
Now I realize that the mental gymnastics to go between brake and gas is not worth the feature. It could even be worse for someone used to a clutch because you'd be searching for the non existent clutch at first.

I think I can safely predict that the next model year for Volt will employ the Bolt EV system in which there is creep in L but not D (or is it vice versa?) Shucks, ya missed it by a year or so.

Actually, unlike with an ICE, it would make very little difference in efficiency...

[mr_raider]

Lack of creep is probably what caused a number of Tesla accidents. When going from F to R the little shudder and creep is what tells your brain which direction you are going in. I don't see GM removing it as the vast majority of drivers are coming from auto transmissions.

If creep bothers you, put it in neutral.

I must be missing some appreciable advantage. Most "cruising down the highway" situations are within a reasonable RPM range for the ICE anyway (through the 7:1), so that's a matter of just clutching in, adjusting the throttle to meet the speed and take on the pulling. Adding in a CVT would add some RPM flexibility, but at the cost of more friction losses and a lot more tiny bits of metal to go wrong, and that'd probably amount to a net loss overall.

Never underestimate the power of expectation.

New car smell has not actually existed for a long time, it was offgassing of volatile organic compounds from new interior components. OSHA regs required their elimination (because assembly line workers were exposed every day for 25 years), and people had a fit because their new car didn't smell like a new car.
So the carmakers made a spray that simulates the smell of formaldehyde and various other toxic gases, and spray it in because that's what we want a new car to smell like.

The same thing with console shifters for auto transmissions.
The same for a burst of static when my XM radio loses signal, or the static on my TV when tuned to a channel with no signal (both are artificially created in the box, there is no static in digital transmission).
Your cellphone generates DTMF tones when you are dialing a number you are about to call. They are only for your benefit, they are the expected feedback when you are dialing a number.

There are all kinds of things, all around you, that work the way they do because that's what we expect. They are the "standards" that we have all learned to use and live with. Start looking around, and you'll be amazed at all the things that are done simply because that's the expectation.

The ICE in gen1 already does have an eCVT. Gen2 is a little different, but effectively has a similar result. Haven't you ever noticed your ICE operating at all sorts of different RPMs while on the highway while your speed is held constant? That is only possible with the eCVT. It even does this in CD mode at higher speeds, to reduce the speed of the motors to be more efficient. That 7:1 fixed gearing is only at low speeds. It becomes unfixed when you unclutch the ring gear.

One of the first things I noticed with GM products is lack of a brake hold option. Having this would allow the driver to stop the creeping as needed or desired. Brake hold is a system where the brake pressure is locked, normally by pressing extra hard on the brake pedal, allowing you to take your foot off the brake pedal at lights, etc. It is disabled by pressing the brake or accelerator. I had this on a previous car and loved it.
