- Hey everyone, Adam Lovelady here,
with Toyota Motor North America,
and I'm here to talk to you about one of our
new technologies, Lane Tracing Assist or LTA.
I'm here with the all new 2019 Corolla Hatchback,
the first vehicle in Toyota's lineup
to receive Lane Tracing Assist here in the US,
but we'll be adding it to several other Toyota vehicles
in the near future.
Let's take a look.
(gentle upbeat music)
(car door shutting)
LTA's one of six advanced active safety systems
in our Toyota Safety Sense 2.0 Suite.
It's designed to work automatically
when two other TSS systems are active.
Those two systems are
Full Speed Range Dynamic Radar Cruise Control or DRCC,
and Lane Departure Alert with Steering Assist,
or LDA with SA.
Lane Tracing Assist combines LDA and DRCC technologies
to create an all new feature.
So both LDA and DRCC have to be on
and active for LTA to work.
This new system uses Lane Departure Alert's
camera technology to monitor the lane markings ahead.
It also uses Dynamic Radar Cruise Control's
Millimeter-Wave Radar to keep the vehicle at a set speed.
And to maintain a pre-set distance
from a vehicle ahead, if there is one.
So by combining these technologies we were able
to add Lane Centering Technology.
This technology is designed to make constant steering inputs
if needed, to help to help the driver preemptively keep
the vehicle in it's visibly marked lane.
As well as help reduce driver fatigue.
The motivation behind developing LTA
is to help prevent unwanted lane departure accidents,
which can often be serious.
So as the system is constantly trying
to keep you within your lane,
it will hopefully help you avoid accidents
that may occur from unintended lane departure.
That said, LTA is still a Driver Support System,
not a Driverless Technology.
It requires the driver's hands to remain
on the steering wheel at all times.
In fact, if they are not,
you'll get a visual alert, like this,
reminding you to put your hands back on the wheel.
And if you still don't place your hands on the wheel
after that, LTA will automatically be disabled
until you put your hands back on the wheel.
(soft beeps)
As I mentioned earlier, LTA defaults to active
when DRCC and LDA are enabled and on.
But it can be disabled
through the multi-information display.
Or simply by canceling DRCC or LDA.
(soft beeps)
There you have it.
I hope this video helped familiarize you
with the new LDA system.
But before I sign off, there are some limitations
to this system that I want to make you aware of.
The lane centering technology is just that,
it is trying to keep the vehicle
in the center of the visibly marked lanes.
So if your lane branches out to add another lane,
or to form an exit lane,
the system may try to stay centered between
the two lane markers as they expand.
Potentially pulling you out of the center
of your intended lane.
Another item to keep in mind,
is that the system is designed
for use on relatively straight roadways.
This means it may not be able to keep the vehicle centered
in it's lane if the curve is too sharp.

Again, please remember, LTA is only meant
to assist the driver,
and does not replace normal steering input.
LTA is not a collision avoidance system,
and the drivers are responsible
for their own attentive safe driving.
There are also some situations
that might cause LTA not work as intended.
Such as if the vehicle has been modified,
or if you're driving in inclement weather
that could be blocking visibility.
LTA is not offered on all TSS 2.0 vehicles,
and it's not offered on any manual transmission vehicles.
Refer to toyota.com or your owners manual
for more details on LTA and it's possible limitations.
