Lane Keep Assist Explained

[Tideland Prius]

ok first off, I apologise if I've confused anyone. I was under the impression that LKA only helped in sudden lane change manoeuvres (as you can see in the demonstration by Nihon Car & Bike) but it is also Toyota's lane departure warning system with the added benefit of the car nudging you back into your lane.

Thanks for the link and the added info. I've been wondering about the full capabilities and uses of the LKA option.

yeah, thats exactly it... warning is LDW, not LKA... they are calling it different things as they do operate in different conditions.

I haven't seen that before. That's really cool. I just wonder why the written comments say that "the movement towards automated driving makes me nervous". I think that would be and may be the eventuality, of course with the ability to disable the feature when needed.

I'd take this whole LKA system over a sunroof any day; especially the adaptive cruise control, and especially if it comes with the 17 inch wheels (I want a stable car this time!).

I would take it too if it didn't cost an arm and a leg. The big problem for me are the roads where I live. Mostly we can't use cruise control, let alone this level of automation. If I lived near highways and multi-lane roads I would be more interested. It would also be more useful if our roads were visible during the winter. I use mailboxes and trees to find the road. I don't imagine LKA does very well with that.

One remarkable thing I saw at the Detroit Auto Show was a diagnostics video from the Denso lane following system showing how it recognizes pedestrians:






As this sequence shows, the system identifies pedestrians at a distance and follows them until they leave the field of view. This is a remarkable system that could result in a significant reduction in vehicle-pedestrian accidents. It also recognizes vehicles and the lane.

Does it have an override, so that we can still hit blind pedestrians? What good is stealth mode if we can't hit people?

Any form of automated driving will make people nervous until they learn to trust them, and trust will come with use and experience. I had not heard of LKA and ACC until the threads of the past few days. I recall a post some time back about a test in a parking garage that ended with the car crashing into a pillar. Clearly, they had not gotten the bugs out of that one yet.

I guess all in all I like both ACC and LKA. I wonder what ACC does in curves where the car ahead moves out of the direct-in-front position. But I'm sure they've taken some measures to deal with it. I'd probably pay for such features, but not if I have to take all the other high-end features (such as 17" wheels and factory NAV and leather seats) along with them.

To add to daniel's sentiment, Cruise Control still scares my wife - she won't use it. Her hwy FE shows too :-(
