AWS

[DCIV]

I’m gonna start out with I do not understand the aws steering at all. I was always curious if we could somehow implement the wheels turning the opposite way at speeds less than 5 or 10 mph. I know some preludes did this and I drove one once and it was amazing!

So someone school me about the entire system.

AWS for the 3/S platform or AWS in general?

[DCIV]

The 3/s platform. I figure since the stuff is already there then maybe parts could be modified or made to make the system work like I asked. But again, no idea of the complexity I am asking.

If I remember correctly the 3/S rear wheel turning is very little, correct? Like not enough to even notice until pushing it at higher speeds? The last AWS steering I was in was an off-road vehicle so completely different.

Because of the way the factory system works the entire system would likely have to be reengineered.

See I don’t think so, the wheels already turn, it’s just what tells them which way and at what speed that would need to be modified. I may be wrong but I don’t think that’s all being reengineered.

Did anyone else have the knee jerk response of "why is Coop asking about Amazon Web Services" ?

Ours sucks. Nissan 300zx’s did it right with electric hicas. Theirs go alternate directions depending on speed.

.015* if I remember correctly. Maybe it's just wishful thinking, but I 'felt' like I could notice it on high speed lane changes as well as taking hard corners. It just felt different than anything else I'd driven.

I'm with you Brian.

The minimal amount that the wheels actually turn, I don't think the roi of re-engineering the whole rear suspension geometry would be worth it and could likely end up being very dangerous...

It’s 1.5* I believe.

The way the system works there is no way to make the wheels turn at low speeds. The rear system is fed from the rack and it goes to a separate hydraulic pump on the back that is run off the diff. The pump only provides enough pressure to turn the wheels above 35mph. There is no way to make it work below that(as the pressure is not high enough). Also with the way the lines are plumbed from the front rack is how it controls the direction the wheels turn. There is nothing in place to change how that works.

It is an absolutely terrible idea to try to reengineer an AWS system that was designed in the late 80s. And making the system work below 5-10mph is pointless, unless you want to be able to pull into parking spots easier. Think about how many corners you take at 5-10 mph and below, and tell me how a better turning radius would be worthwhile in those situations?

[DCIV]

So hypothetically if you wanted to do it then you would want to do it like the 300’s with an electric pump to have pressure when you needed it and then just need a way to control them which way you want them to turn.

Late HICAS are run by individual electric motors. No hydraulics.
