Lane keep assist annoying beep

Middle steering wheel button on right side. Right of heated steering wheel left if dynamic cruise control spacing.
It’s sticky so you need to turn it on yourself.
Or
Use turn signals when changing lanes.
Or
Actually stay in your lane?

 

You can adjust detection sensitivity too.

 

On my 2016, there is an on/off button on the right side of the steering wheel next to the cruise control adjustment. This pic is not correct, but shows the arrangement of the buttons. Maybe later models/Primes don't have this switch...

 

It’s a toggle. Press once off. Press again on. There is an indicator light on the right lower dash that toggles on and off as well.

 

The prime has a button on the right side of the steering wheel with a car veering off the lane press it and the M.I.D should say that its off. If that doesn't work the dealer shouldn't charge u to fix it.

 

For me, it almost never goes off unless I really am creeping over lanes. The only reason I can think of for why it might beep a lot at you would be if you’re not using turn signals...? (Not criticizing; just suggesting a possible explanation.)

 

If driving on reasonable roads, I wouldn't mind it. However, driving in Houston it drives you nuts. Our lane markers look more like spaghetti than lane markers. This is due to all the construction going on here. They redraw the lane markers, but don't mark out the old ones. This, the lane change warning is always going off.
Brings to mind a question I have: Do those self driving cars use lane markers to do their navigation? If so, self driving cars would never work here.

 

Having recently taken a Thanksgiving trip to Houston (and having grown up there), I saw one especially-bad case of that myself, although most lane markings were pretty clear. All in all, it doesn’t seem like I got beeped at a lot during that trip. Then again, I didn’t take a really careful tally of times when it may have “thrown up its hands,” and turned off the LDA system.

As for self-driving cars, two things: There’s a lot of different kinds of self-driving technologies, each with its own advantages and disadvantages. Generally speaking though, damaged or otherwise unclear markings are among the biggest challenges for autonomous-vehicle designers.

Even here, I see places with three contradictory sets of lane markings. One only is current, and probably best visible in dry daylight. But in construction zones. the previous two will be painted over but still visible from glossy wet reflections, sometimes even the most visible when facing into a low sun after a rain burst. Even after construction is complete, some of these obsolete markings take a very long time to wear away. The ones removed by pavement grinding can remain detectable for years. And the concrete pad lines remaining after old lanes are realigned, will never go away.

In heavy traffic, this can be hard enough for humans to figure out, and not all of them get it right even when paying full attention.

 

I'm not at all surprised. In certain light and weather conditions, the old (and now incorrect) marks sometimes show up better to my eyes too.

 

Sadly, there is little logic in the lane keeping assist system. It fails to recognize the location of adjacent cars to keep a wider birth when they are close to the lane edges (still staying in your lane, of course). It also fails to prioritize lane position by the lane you are traveling. For example, in a 2 lane road it should hold you close to the shoulder side away from the oncoming cars. Driving in the far left lane of a divided highway it should hold you closer to the inner shoulder line. These can all be done simply with programming, and greatly increase safety. Instead, being a defensive driver, you are constantly fighting the lane assist. Another fail by Toyota engineers. Hope they fix these flaws in future generations.

 

To me, that sounds more like consumer expectations getting ahead of current product reality. These products are still at the Level 2 stage, far short of self driving cars. I don't believe the programming is as simple as some believe.

 

My Prime has the beeping. My other car has the steering wheel shake. I like that a lot more. I agree mine rarely goes off. Usually when I am avoiding a pot hole. Using the turn signals help.

 

For me the question is not turning off Lane Keep Assist, but it is USING Lane Keep Assist without the annoying lane departure beep.

Can you use the system without the beep?

 

I don't think so, but that would be nice. I had LKA turned off on my previous PPs with TSS1.0. But with my new 2021, TSS2.0 has improved the LKA with a much better steering correction response. Yeah, the beep is annoying enough to keep it turned off, but if I can use it without the beep... Humm, that may be good.
