Crawl mode?

It's like the difference between ABS and pumping your brakes. You can do it yourself but the computer can be much more precise. The area I see Crawl Control really benefiting is in down hill decent... I'd like to try it out though and mess with it myself.

 

Stupid gimmick nothing new.... Hummer H1 also had a version of called TT4..

 

Just because it's not new doesn't mean it's a gimmick. Does it work? From all the videos I've seen of this on other Toyota vehicles, I'd say it does work pretty well.

 

In the hummer application the driver controls the throttle so, not at all like the Toyota version.

 

I give up.

Had some time at lunch... As stated beware of audio pollution. Good demonstration of CC working and getting out in less than two minutes.

 

I don't care if it's a gimmick. That was pretty awesome. I've seen trucks with lockers on both ends unable to get out of being stuck in shallower sand than that.

 

Yea and you control crawl mode with the button... You still have to turn it on. Plus the Gearing in the hummer is so low.. You don't have to press the gas or the breaks.. Pretty much does it for you. I know from first hand experience. It's mechanical vs technology.. It's not all what it's cracked up to be.. To me it's being lazy... woohoo!!! Your computer got you to the top of the mountain..

 

Jetboy from mud on crawl control...

As for lockers vs crawl control - I'll take mechanical lockers any day. No matter how good traction control is, it's not as good at going the last mile offroad as real lockers, but it might be better at cruising around logging roads. The reason is that crawl control still requires wheel slip to engage, and that means you've lost static friction and now have kinetic friction on the tire that slips. Static friction is much greater in most situations than kinetic friction. So with crawl control you can achieve essentially the maximum static friction on the tire with most traction and kinetic friction with the other. With a locker you can get the absolute maximum static friction from both tires on the axle. So for me, ARBs would be my choice over crawl control - or any other traction control system.

 

I'm pretty sure it's the other way around. With Crawl Control the computer is identifying which tire is slipping and moving power to the other wheels. It's trying to maximize the static friction by stopping tires that are spinning. With a locker, both locked wheels are turning the same whether they have traction or not. If only one wheel has traction, the other could be digging in deeper.

 

This is a contrived test under special conditions. During the ice storm years ago, a Army Guard Humvee broke through the ice into the snow below and had to be winched out. No fancy electronics will help you there or deep mud or wet snow. You can move dry sand at times.......otherwise, have a cell phone handy.

 

Few if any of these traction aids are as good as open front and rear differentials and chains in deep snow. On ice, regular traction control in 4 wd high with the trac off so the engine shut off is best. Winter conditons are differnt then traditional off road. If you have deep wet snow and you can't spin your tires to keep your treads clear, you will stay stuck. You can leave crawl control on for an hour and co me back 30 days later and it will still be stuck in some winter conditions. This is why on off road model that I have, and I hope the new ones, you can defeat all your off road traction aids and just use 4 wd with open differentials and little to no help from traction aids. Some times...old is better. Bouncing through deep mud, like wet snow works better this way too. Well, at least you get to spray mud everywhere. The advantage is, when I parked my Tacoma at work after a weekend of mud work, few would park next to me.....

 

I would

I would think , ideal conditions , are needed.

 

can i do a manual crawl control on a 4x4 with auto lsd(no rear locks). and how?

 

you get TRAC, a weak form of ATRAC. It won't control its speed, but it will try to control the speed of each tire

 

and this is done with L4?

 

I love these threads...

I try to keep life simple.. if front and rear lockers were better than Crawl Control, the Land Cruiser would come that way, but it doesn't.
So, since Toyota's offroad flagship vehicle has had crawl control since 2008, one can only reasonably conclude crawl control works better under the majority of off-road situations. Crawl Control is not new technology, it's just new to the Tacoma. It's been on the 4Runner Trail since 2010.

I know change is hard but sometimes, it's for the best.

I can't wait to hear what people on this forum say about when the Tacoma gets KDSS... wait for it, it's coming for sure in this generation at some point.

 

I want to see it do something when its in mud or stuck in boghole.

They always show it being used in their own set up.
I want to see some videos of it out on the trails to see how well it actually works.

 

This is my opinion only, it comes down to what each person considers "offroading". If you want every modern convenience to keep you and the family from getting stuck at a muddy campsite, then crawl control is for you.

If you think getting stuck and the ensuing extraction is part of the fun of offroading, then maybe crawl control isn't for you.

For me, I like to keep the systems I truly depend on as simple as possible. Mechanically and electrically simple. Will crawl control keep me from getting stuck once or twice on the trail? Sure, but it's still not a system that I think will replace a winch. More than likely, that winch will be used to get me out of something during the day, so what's one extra time. Plus, the challenge of figuring out how to get myself out of a sucky situation part of the fun of offroading for me.

 

I see a lot of off road videos in Australia where they use the Land Crusier from the 80s. Actually remember watching a review where the guy was comparing it to the new ones and said he much rather have the old one than the new.
