LANE KEEP ASSIST/Centering - do you use it?

Mine does the same. It’s pretty cool though as it will actually negotiate a curve if the lines on the road are well defined. I’m somewhat disappointed with the cruise control as well as it seems to be somewhat jerky and not well controlled; not smooth in traffic.

 

I think you can also adjust the sensitivity too guys

 

True, I’ve tried those settings and didn’t see much difference. Someone suggested to possibly have the system recalibrated but I’m not sure if that’s the issue.

 

I love the Lane Assist feature. I've only tried the Lane Centering once and I wasn't a fan. Don't get me wrong it did its job well even on a good curve. However, I couldn't stand having my hand/fingers on the steering wheel while it was on. It just rocked back and forth way too much for me, yet you couldn't leave your hands off but a few seconds. I felt like an actor "driving" a car with exaggerated movement.

 

NO.....HATE IT

 

I use it on the highway. I have about 10 minutes on the interstate every day to work where the adaptive cruise is nice when traffic gets busy; I can sit back and relax and it does the stop - go work for me.
I do the I-95 trip between Florida and New York several times a year. Lane centering is nice when I get bored and start to drift, so it keeps me in my lane. My only concern is that it does so much of the driving that I will fall asleep and won't know it.

 

It really doesn't work well. Once in awhile on some roads it is just OK, but on others that seem to be marked just as well, not. You just really can't count on it enough to benefit from the feature. And the way it requires you to "fight" it just a bit to show that you are holding the wheel is a PITA. It would be better to have some sort of touch sensing technology... or make the current technology a bit more sensitive to driver inputs. I have not driven a Honda with their implementation but most reports say it takes you right down the center. I was hoping the Tundra would do that. But, no.

 

I have a 2020 1794. I have driven several newer vehicles (including Toyotas) as rentals. I may be Old School, but I am an ACTIVE driver. That means I pay attention to the road and what's going on around me. I've used the Adaptive Cruise Control and like it for long, medium speed, two-lane roads in town, but I hate it on the interstate. It is too easy to be driving along and realize that I am driving 10 mph slower than I set the cruise for because of a slow driver in front of me. That tells me that the ACC is lulling me into not paying attention like I should. Regular cruise control forces me to decide whether/when to pass based on traffic in the left lane.

I absolutely hate the lane assist features. Some roads have potholes that I actively avoid, requiring me to cross the center line from time to time. I'm obviously paying attention to traffic, but when it's clear to avoid rough pavement, I don't use blinkers. I also don't like it on the interstate for some of the same reasons I don't like the ACC. I think the more I depend on the nannies, the less aware I will be when something starts to go wrong, and my reaction time will be slowed.

 

I turned lane assist off. It was too sensitive and it would exaggerate and overcorrect.

 

I like these on the open interstate , thats about it.

I found you have to turn down the sensitivity to get it to not move you back and forth too much.

In general, I just like to drive myself, these new tundras steering is weighted really well and it fun to drive

 

I tried both lane assist and centering for the first time on a recent long road trip. I hated both features. At one point while using lane centering, my wife asked why I was swerving back and forth. It was actually making her car sick. Adjusting the sensitivity didn't help. I won't ever use either feature again.

 

It’s very clear many of you never bothered to read the manual to understand the settings, capabilities or limitations of this system. Please stop making sweeping negative generalizations when you can’t be bothered to spend 2 minutes learning how these features are supposed to work.

You remind me of my mother in law claiming “you know four wheel drive is a total waste of money it doesn’t actually help.”
Yes that is how you sound. You probably were the same ones that said you’ll keep you mapsco and CD’s as early GPS and MP3 systems didn’t work for you either.

If you ever bother to read the manual you will find these systems work just as advertised within their well stated limitations. No it is not Ford’s Blue cruise or GM’s Supercruise or Tesla Autopilot nor does it claim to be. Having driven all of those I would be far more dissatisfied as an owner with GM and Fords offerings as their advertising would have you believe the tech is far more capable than it is. I took an Escalade on a 400 mile interstate trip and the supercruise worked ok for all of 40 miles, then threw a code and all driver aids were unavailable for entire rest of the trip. Was I surprised? Not really.

Toyota is rolling this driver aid tech out just like everything else they do, prioritizing dependability and safety above all else.

 

The reflector pucks or discs on some highways will cause Lane Centering to the steering wheel to go back and fourth, I’m not sure of exact wording in owners manual off top of my head. My truck does it, but it also works as advertised in manual and without those pucks works nice.
I leave lane assist on all the time, pretty nice once your used to it.
So you simply switch back and fourth if you want with the touch of switch. Those reflector pucks are on almost all the highways where I live.

 

Get off your soap box. I know how the features work. I just don't like them and don't use them.

 

Thanks for your take on the latest Automotive technology. Might I also confirm your prior comment saying you can’t be bothered to use your turn signals? If correct, maybe you can start a new thread questioning Toyota’s decision to include blinkers?

 

I fire people who twist the truth the way you do. First, you accuse those who don't like certain features of ignorance in their proper use, then you twist what I said into an entirely different statement to try to paint me in a bad light. Not everyone uses all of the features on these trucks, and there is absolutely nothing wrong with that. In fact, the title of this thread prompts exactly the kind of discussions that make up most of the thread. Your magnanimous accusation that those who don't like the way those features work do not know how they are supposed to work is arrogant, condescending, presumptuous, and adds nothing to the conversation. Again, get off your soapbox.

 

So specifically what is it you don’t like about how the features work? (Magnanimous minds would like to know)

**reminder: failure to monitor your speed, the speed of other vehicles and/or failure to signal are not issues Toyota is currently claiming to fix for you with these features. However, a good salesman will tell you that exact technology can be found at your local wife store.**

 

No. I don’t need the system to respond if I forget to signal during lane change.

 

As if on cue, you verify and validate my previous response. Thanks.

 

Ok boomer.

Love your Thomas Sowell quotes BTW.

 

I agree that a "hey stupid" alert would likely be helpful on a very long road trip where you could get tired and drift. My 21 is the first vehicle I've had with any type of lane assist system. Next road trip, I will likely activate it.
Otherwise, no. I can actually drive, I pay attention and I'm coordinated. If I need my car to drive for me, then I shouldn't be driving, I should be on a bus.

 

A number of you are mentioning that the truck is weaving between the lane markers "like a drunk" and the system is annoyingly beeping at you and therefore you are "disappointed" or "never use it anymore".

You are in Lane Departure Alert with steering assist mode.
You are NOT in Lane Centering mode.
The truck is doing exactly what you told it to do!

Here it is direct from the manual along with the previously mentioned limitations.


Lane departure alert function
When the system determines that the vehicle might depart from its lane* , a warning is displayed on the multi-information display, and either a warning buzzer will sound or the steering wheel will vibrate to alert the driver. When the warning buzzer sounds or the steering wheel vibrates, check the area around your vehicle and carefully operate the steering wheel to move the vehicle back to the center of the lane.
Steering assist function When the system determines that the vehicle might depart from its lane, the system provides assistance as necessary by operating the steering wheel in small amounts for a short period of time to keep the vehicle in its lane.


Lane centering function: This function operates ONLY when all of the following conditions are met.
• LTA is turned on.
• Setting for “Lane Center” in of the multi-information display is set to “ON”. (P.573)
• This function recognizes a white (yellow) lane lines or the position of a preceding vehicle (except when the preceding vehicle is small, such as a motorcycle).
• The dynamic radar cruise control with full-speed range is operating in vehicle-to-vehicle distance control mode.
• Width of traffic lane is approximately 10 to 13 ft. (3 to 4 m).
• Turn signal lever is not operated.
• Vehicle is not being driven around a sharp curve.
• No system malfunctions are detected. (P.255)
• Vehicle does not accelerate or decelerate by a fixed amount or more.
• Steering wheel is not operated with a steering force level suitable for changing lanes.
• ABS, VSC, TRAC and PCS are not operating.
• TRAC or VSC is not turned off.
• Hands off steering wheel warning is not displayed. (P.254)
• The vehicle is being driven in the center of a lane.
• Steering assist function is not operating.
• When your vehicle is not towing a trailer or during emergency towing.

 

My lane centering definitely bounces from side to side. Haven't tried to adjust sensitivity though. Glad I saw this, because I have thought its just annoying and not super helpful, but maybe bumping it up will improve it.

 

Oh my god, the boomer energy is strong here lmfao.

I started using the adaptive cruise control on the freeway recently and it's pretty cool. Still hover over the brake pedal and I agree the braking is more aggressive than me. I like to cruise nice and easy for those high 2 digit MPG numbers. I wouldn't trust any of the assistance with my life, and shouldn't have the expectation since it isn't advertised as such.

 

Not sure what generations have to do with the fact that Lane centering on these trucks is a joke. It pinballs back and forth in the lane just like a drunk driver. Adjusting sensitivity doesn’t help. I found myself way more on edge while using it If that’s considered “driving assist” to some of you, then perhaps you should get a chauffeur. And, yes, I’m a boomer who knows how to drive smoothly between the lines without even thinking about it.

There's an entire section in the owners manual on things LTA can't figure out - here's a sample. And a good idea when NOT to use it. See the manual for all the cases. and there's probably some it doesn't cover...

 

I read all of the disclaimers in the manual. So I made a point of only using Lane Centering where the lines were clearly visible on straight roads, and there wasn't any other traffic around. It still sucked. The problem is, when the system detects the truck getting too close to a line, it over-corrects the steering abruptly, causing the truck to jump too close to the line on the other side, then it does it all over again. This causes an annoying "pinball" effect, which is very noticeable to both the driver and passengers. Like I said, it made my wife wake up from a nap and ask me why I swerving so much.

Not all of the driving assist features are bad. I love the adaptive cruise control. The LTA features, on the other hand, need a lot of refinement, IMO.

Matt

 

The US road system needs a few refinements.

 

I agree 100% with you on this (I use the ACC all the time, it actually gets me better mileage then I can get on my best days. LTA is not there yet) - I'd mentioned the ping-pong ball affect way back earlier in this thread. I was just pointing out all the places (and prob more) where it has issues.

 

Once again all of you folks describing the truck “pinballing” or “swerving” between lane markers ” even on a straight road with clearly visible lane markers are in lane departure with steering assist mode. You are not in lane centering mode.

However boomers take heart, in other news Toyota is releasing a new trim level, the Tundra SE! Official marketing reveals this will be the “special edition for special people”. However internal memorandums indicate the internal code name is the “ silver edition”.

Unique features limited to to the SE trim package include the following:

- New Jitterbug infotainment system with “Classic LCD”. Dealerships hard programing of preset a.m. radio stations and emergency family contacts included!

- Two speed power wipers. Regular and Turbo speed.

-Available Luxury velour seating

- Two sets of keys included

-Enrollment in your first year of AARP with roadside assistance including checking your tire pressure, oil and water level.
