To clarify, ELKA and LKA are two different systems. Emergency Lane Keep Assist (what is shown in the picture) can be manually disabled when your first start the vehicle. It will always reset after the car has been turned off. We can't tell when drivers switch and we can't permanently allow people to disable important safety systems. That's a lawsuit waiting to happen.

Lane Keep Assist is what's accessible on the steering wheel controls and your dashboard menu. This allows you to toggle the system on and off with a simple button press.

If you're experiencing problems with the system it's important to remember that it's a camera based system (located in front of rear view mirror). If the windscreen/windshield is cracked, stone chipped or dirty in this particular area it can cause issues. Also note that sunlight at certain angles during the day can create some system confusion in the system.

If everything appears to be 100% and you system is not responding to your steering wheel controls or operating in an erratic manner it could be the case there is an issue with the camera or calibration. However, in many cases that are escalated we often find that user error or poorly maintained road systems are a key factor.

Hope this helps.

 

Basically in a two-way traffic double line situation you're trusting your life to sensors and camera systems that can and do sometimes malfunction. Sometimes you need to go outside of lines abruptly to avoid other vehicles that are swerving into or are stalled in your lane etc. Though I'm sure it handles some things properly it's unlikely you're going to have 'code' that accounts for when to take control of the wheel automatically in all of these situations. Your code may sense what I do but it's the other cars you need to worry about, these situations can be unpredictable. I'd rather die by my own hand. fwiw. I know having to disable this every day is not the answer I wanted hear, and that goes for any feature really.

 

@Chief65 - You make a lot of good points. In my mind, this is one of consumer preference. So I think there should be sufficient CYA for JLR to put out disclaimers and then let people choose which way they want to roll the risk dice. On one hand, I would NEVER ride on the back of someone else's motorcycle. No way would I risk my life like that. On the other hand, I volunteered as an EMT for almost 30 years. The most carnage I ever worked on was always because of auto accidents. There's a 1:6,000 chance you are going to die in a car wreck. I always drive nervous. So when everyone talks about autonomous vehicles I'm always entertained. Everyone is "shocked" when one has an accident after a million miles. Or if a lunatic driver does something and it still wrecks. Frankly, I'm not looking for a perfect AI/machine driven vehicle or safety system. I'm just looking for something twice as good as a person. If the chances improved to 1:20k, sign me up every day of the week. I've seen first hand the gore and tried to wipe it up and put humpty dumpty back together. I get that my auto, emergency feature isn't perfect but it's a LOT better than our imperfect selves. There are many drivers better than me and I accept that they can dig in there and turn it off. But for the vast majority of drivers, I'm also good with all the safety features starting in the "on" state and deep in the bowels of menus to change.

 

Our systems (and pretty much everyone else's in luxury) are meant to try and step in when it appears you have missed your opportunity to do so. You don't put your life in our systems hands because we are not offering you an autonomous vehicle.

So far though, we've saved a lot of lives and prevented many accidents (typically with forward collision and adaptive cruise). Many people looking down for a moment or texting suddenly crash into the rear of a vehicle. That's going to be a thing of the past in the coming years as more and more newer vehicles with these systems get on the roadway.

We partnered with universities to test these systems and observed thousands of miles of driving with consumers. We watched (with special cameras) how the average driver behaves in their vehicle and in traffic (along with their choices) and it's downright frightening. People eating bowls of cereal, going 80mph in "breakdown" lanes, people watching movies, people running lights, driving on sidewalks, fumbling around in the backseat, etc etc. Driving behavior in certain countries (and the licensing process) is dreadful.

The systems work very well in general and are improving at a rapid rate as we learn more. However, it's a challenge when some roads resemble something from a Mad Max movie.

 

Lol it sounds like youre describing NYC? Its the wild west out here. I find that im constantly driving in a defensive state.
I also prefer to turn it off. The roads where i live are not maintained and the system intervenes very frequently. Its dangerous. Id be more than happy to submit my vehicles data to further refine it but in its current state, its a liability. I recall reading, on here, regarding the defender that drove off of a road rolling itself and its occupants because of these so-called “safety features”.

 

Sounds like someone who wouldn't take responsibility for their own crappy driving.

It doesn't steer. It just nudges and is easy to override. No different than changing lanes without a signal. It makes itself known and you just keep aiming the wheel.

 

One reason why I enjoy my BMW's, it allows you to setup your driving features and they stay in what they call individual mode, or full on or full off..... I might have to consider this as we are looking to order and really do not enjoy a wheel being yanked around while driving. It's not a lawsuit waiting to allow the owner to disable a feature, because it is not a required feature by law to be on the vehicle say like the safety belts.

 

How are the two systems we’re talking about in this thread different? What’s the purpose of having both of them?

 

You can most definitely disable LKA and not worry about it with a simple press of the button on the steering wheel. However, LKA and emergency LKA are two different things. Both systems will only operate above 40mph. LKA is meant to be a helpful minder if you get distracted and start to drift giving you a gentle tug. ELKA only activates when the computer has calculated that an emergency situation is imminent. In summary, LKA= a helpful reminder, ELKA= we think you're about to have an accident.

Both can be disabled, LKA being permanently (last I checked) and ELKA defaulting on. Honestly, unless you have unique circumstances (are on a track, doing high speed off-road rallying, etc) you really should just leave it on.

In theory, ELKA should not be interfering with everyday driving. However, it does err on the side of caution and unusual features can cause it confusion. In fact, I've only experienced it a handful of times-most recently when entering a tunnel with merging lanes and road construction debris strewn in between lanes. That said, if you have ELKA popping up daily something isn't right.

 

I've been teaching my 16yo how to drive and we're at the point where we're into accident avoidance, debris on the road, losing traction, tire blows out at high speed, right side of the vehicle goes into the grass... I'm taking him to a teen lesson on this same stuff at the Porsche Experience in Atlanta tomorrow.

That begs the question, does ELKA behave like LKA in that I can overcome those ELKA inputs with my own steering or does it take over more and nullify my inputs?

I want to know what to expect at that worst-case moment so I'm not surprised by the way the vehicle responds.

First time I drove a car with anti-lock brakes for example, I was surprised by the vibration at a hard stop on a wet road. I ended up instinctually fighting the ABS and made it all worse. Now I know what they do and I know how to work with them.
