don't listen to him, he's a TL driver

 

They do not have TL's in the UK. Sounds like a Legend. I wish we had LKAS here in US.
Pint - Do you use LKAS? Let us all know how it works and if its useful please.

 

No, we don't, you are right. In fact we don't have Acura either. Honda only. :wink: Legends are no longer available. Honda decided to withdraw them from model range available for sale from this year. Latest second hand can be found 2009 production, but rather rare.
I am using all systems, buttons, everything it has. LKAS rather interesting. As warning system, it does great job, correction abilities are not superbly effective, but helpful. It seems to me the system has been limited by Honda with intention. It is obvious, that system can do more intensive steering, but manufacturer decided to minimise its involvement, may be not to scare some drivers, may be for some other reason. It rotates steering wheel to approx. 15 deg to each side (visual observation). Capable to do mild bend on around 70mph on its own. But hands must be on wheel all the time anyway. When it detects hands off, it is beeping and asking to put hands back on the wheel by flashing special amber sign on information screen. Checking is going every 10 seconds approx. On long motorways trips LKAS+CMBS+ACC are extremely valuable. It backs up you vigilance greatly. It is like another pair of eyes attached to the brain with much quicker reaction that humans.
I was travelling through Europe, where they have left hand driving roads and LKAS was doing its job with the same effectiveness as at home with right hand driving roads. So, I do not really follow, why LKAS is not available on left hand cars.

 

Here in the US, where blame is paramount, the lawyers would bankrupt American Honda in a heartbeat after the first accident if they knew LKAS was enabled.

 

I agree with that. I can just see it being used on roads that do not have clearly painted lines, with curves less than 230 meters radius and the accident happening, and Honda getting the crap sued out of it. I think that you also won't see infrared camera option that looks for pedestrian like shapes. It does not work in extremely hot ambient temperatures, where it becomes difficult to distinguish body heat from the background. First accident and another law suit.

The LKAS technology was announced in 2002
http://world.honda.com/news/2002/4021010.html,

and here is a diagram from 2003 that explains with some pictures

It is pretty cool technology but a cold day in hell before we see it in the US.

 

It beeps and produce warning on the information screen immediately as lines are lost. And when it picks it up again, screen and beep inform you about that system is back “on line”. It is very informative, all you need to do just pay attention to what it tells you. From my experience it tracks lines very well, even if they are barely painted, even, which is mostly the case in UK, on wet road.
But I agree, if someone wanted to pump out some cash from the manufacturer, then there is always something to be blamed.

 

What does it do if you have to suddenly swerve to avoid animal, etc.?

 

LKAS won't do that. Driver must do it himself as on any other car. As I explained steering is not that sharp. It is up to CMBS then to avoid collision. But I'm not sure about animal. With sudden vehicle in front of you it works following way. First thing is amber brick on info screen "BRAKE", then it starts braking itself at the critical moment it also tightens seat belts. Auto brake is extremely efficient. Reaction & action taken, just in blink of eye. From 40 mph to 7-8mph few seconds. Also it works not only with distance to the car in front of you, but it works out speed of approach one to another. That is the impression, I have got.

 

I understand that LKAS won't swerve. Also understand passive systems that give warning, but I was wondering about the active LKAS that applies torque to steering when it senses a change out of the lane without blinker. I'm assuming that it does not try to steer car back into lane in certain maneuvers.

 

When you steer, LKAS does not interfere. In other words, you do not need to apply additional force to overcome force applied by LKAS. It is very gentle.

 

I see, thanks

 

If LKAS requires a blinker for a lane change to deny intervention then that is another reason that LKAS will not be in the US. Most US drivers do not know that blinkers exist yet alone use them. There is also a theory that BMW's in California do not even come with blinkers!
