Eyesight question

[yuppiescum]

I’m thinking of getting into a legacy. I’m really hoping to get a vehicle that handles congested traffic like a champ. Does eyesight do “Low Speed Follow?” That is, how does it work when you come to a complete stop? Does it restart itself or do you have to tap the gas or the resume button to get going again? Thanks!

[Pronto]

If you come to a complete stop it will restart and follow traffic in front of you. I tried it out on a highway during some stop and go traffic, works great. Its a great system and I'm very happy I have it.

[yuppiescum]

That’s terrific thanks! I think I’m gonna go for a test drive this weekend.

If you come to a complete stop, 0 MPH on the speedo, for more than a half second (not the exact value, but you get the point) you either have to tap the gas or push up on the steering wheel ACC control. But if you are crawling at even 1 mph, it will happily follow. Its great for rush hour commutes.

I guess I'll have to test that out on mine. I'm certain that when I came to a stop before I didn't need to press the gas or touch the controls. But maybe I didn't stop for long enough for the system to register a long stop.

One of the coolest things the car (Follow) does and I have only used it once. I think I have forgot how but I'll try it again here if I hit a highway or traffic. (I'm usually on back roads vs traffic) Love RAB and what I really appreciate is Cross Traffic Alert. I'm parked and can't see by the bleeping truck parked next to me but right when I throw it in reverse, I get a alarm if someone is heading across / behind me exiting the parking lot. Since this all happens before I can even see the car, it''s pretty cool. No more creeping out slowly to see if anyone's coming..

Try it out when you are driving around town with traffic lights. Just be watchful till the thing on the dash changes from Set to Hold; else if the guy in front turns, it will try to speed forward.

Yea, definitely want to try this out. Either way its an amazing system. I've had the car for over two years now and I'm still amazed by Eyesight.

I’ve heard that when you use the follow function, especially in stop and go traffic, your brakes will wear out a lot sooner. Anyone have any experience with early wear brake pads

I don't see that it's going to be a major issue, I have used it quite a bit and it's not really different from the ordinary driving you do.

 

And if you have been stopped for more than a few seconds then you have to resume, like with a flick on the +/- switch on the steering wheel. But it's a safety matter since what would happen if you'd get disturbed at a temporary stop? People has a tendency to do the weirdest stuff when stopped in a queue waiting for it to get moving again.

If it goes full stop three times during your drive does EyeSight disable itself? The manual seems to suggest that.

There's a guy on youtube that tested eyesight with cardboard boxes. It did disable after 3 panic stops in one drive.

No.

No, it doesn't. Pre-collision braking is not the same thing as normal ACC operation.

[Pilot1226]

Gotcha. Why would it disable itself after 3 PCB events? Liability thing, like if someone was under the influence and shouldn’t be on the road?

[ehsnils]

If the queue you are in is stopped for too long it turns off but keeps the car stopped.

[ammcinnis]

I don't know, so I won't speculate.

 

I will say, based on personal experience, that even one PCB event is highly unusual. Three PCB events in a single driving session would indicate to me that something ... most likely the nut behind the wheel ... has gone terribly wrong. I will repeat that PCB is, by definition, a last-moment emergency intervention. It's not at all the same as ACC's usual mild braking to maintain safe vehicle separation.

that's where eyesight says "eff it, I'm outta here before I die"

I’ve been playing around with the adaptive cruise (it’s new to me). It’s fairly sophisticated but I still won’t use it for my regular commute. There are too many sudden stops and lane cuts by other cars. I’ve had regular cruise control I virtually never used the past twenty years. I’ll use it more often now, but only in more widely spaced traffic than I get in rush hour.

[ammcinnis]

If you've read the manual, you already know that's exactly what it's designed for ... and not for congested, urban, or stop-and-go traffic. Just because ACC will work ... most of the time ... in a congested driving environment doesn't mean that it's a good idea to do so.

And it's in congested traffic that it's most useful and works really well.

[ammcinnis]

To you, perhaps. I agree that ACC is useful and that it works remarkably well in those circumstances, but that is also the traffic regime that's most dangerous if the driver relinquishes control, expecting EyeSight to function as an autopilot rather than as a driver assist system. There is substantial personal responsibility associated with using a safety system outside of its design limits.

 

The laws of physics are rigidly enforced, and ignorance of the law doesn't grant any exceptions.

When I picked up my car from my mechanic after getting my suspension work done he said something like the rear brake calipers are electronically controlled but the front are normal. That would lead me to believe that the rear brakes are what activates under Eyesight. That being the case you're only using half your brakes and not even the set with the biggest workload. It makes sense that you'd wear through them quicker than normal.

[ammcinnis]

... my mechanic ... said something like the rear brake calipers are electronically controlled ...

 

Only half true. The parking brake is electrically actuated, but the regular braking is hydraulic, under control of the ABS and VDC systems.

I thought so too for the first few months of ownership. Now I never use ACC in congested traffic. The system knows two things- go or stop. I don't enjoy the car pounding the gas to immediately slam on the brakes every few feet.

My experience is the opposite - when traffic starts again it's not keeping up very well and I have to support it with added throttle.

 

Not sure if it's a question of market or model year behavior though.
