Adaptive Lane Guidance

[Jondalar]

Hi,

My car came standard with Adaptive Lane Guidance activated but it was turned off. I've tried it a few times now and every time I end up turning it off again. Without the adaptive feature active it gently nudges the wheel when you get too close to the sides of the lane and mostly leaves the steering wheel alone. In adaptive mode mine seems to weave it's way down the lane first veering to one side of the lane then the other, as if the lanes are not wide enough for it or something.

Has anyone else experienced this? It's happened to me on pretty decent roads such as the M1 / Bruce Hwy to the north of Brisbane.

Thanks,
Karl

MY18?

You loss TJA if you disable ALG.

Nothing is perfect regarding how ALG and ACC are performing.

That’s how it is.

Yeah MY18 Passat Alltrack Wolfsburg. No TJA in these yet. Pretty happy with ACC and normal lane assist just not the ALG.

MY18 all comes with TJA

You need to enable ALG to use ACC at low speeds.

No problem with mine, even on roads with only a centre line and the pavement on the left.

I just wish it didn't tell me to put my hand back on the wheel after a couple of minutes, it'd drive itself then

Nope it doesn't, as per brochure and actually driving it has no TJA. Also wrong about ACC, it is fine with slowing to a stop and commencing again with a tap on the accelerator with ALG turned off. TJA is an option on Golf 7.5 but has not come to Passat yet.

From the brochure:

Adaptive Cruise Control (ACC)
Adaptive Cruise Control (ACC) is an extension of the conventional cruise control system
with advanced capabilities based on a radar sensor. When ACC is activated, the vehicle
automatically brakes and accelerates to a speed and distance set by the driver.
If the Passat approaches a slower vehicle, the ACC brakes the car to the same speed and
maintains the pre-selected distance. Even when a vehicle pulls into the same lane in front
of you or slows, your vehicle is automatically decelerated to the pre-selected distance.
If the vehicle ahead moves out of your lane, the Passat then accelerates up to the preset
desired speed.
Deceleration of the vehicle may take place via intervention in the engine management
system. If deceleration via engine torque is not sufficient, brake intervention takes
place, braking the vehicle to a standstill if the traffic situation necessitates in vehicles
equipped with a DSG transmission. ACC can be reactivated automatically by depressing the
accelerator pedal. In vehicles fitted with a manual transmission, the system is automatically
deactivated at speeds below 30 km/h and the driver is prompted to take charge by visual
and acoustic signals.
The dynamics of the ACC system can by individually varied by selecting one of the driving
programs from the driver profile selector also available as part of the driver assistance
package.

Interesting.

You may check the PDF SPEC of Passat from VW website.

If yours doesn’t come with it, unfortunate mate.

Well I've downloaded the specs for the Passat sedan and Alltrack wagon from VW Australia, nothing in either about Traffic Jam Assist.

Just checked.

VW updated The SPECs recently.

No TJA info anymore.

Probably they left TJA for Arteon and Rs only now.

No ideas.

Really sorry if you don’t have it mate.

Try activating ACC when you drive under 60KM/H with ALG enabled.

If the car follows front car, you have TJA.


Tried TJA with MY18 Passat for replacement when my car got serviced.

ACC will take the car down to zero km/h, and will accelerate away again if the vehicle in front moves within the short timeframe reqd by the system - that is not TJA, that is just the way ACC works.

What I mean was whether ACC will work at lower speed as well as the lane assist ALG.

You can’t set ACC speed lower than 60 (can’t remember exactly) if you don’t have TJA.

Anything lower than 60 with ALG is TJA

yes, you can set ACC speed lower that 60 - works on both our cars. ALG drops out below 60 on both our cars. Neither mine, nor my wife’s cars have TJA.

Below 40 then maybe.

ive seen 32km/h on mine once, when I was lazy, pulling away from the lights I decided just to accelerate using cruise....hit the ‘set’ button, then used the increase button to bring it up to the speed limit. Just happened that I was doing 32km/h when I hit the set button.

I have not read anything in any of the user manuals to indicate that there is a difference “minimum set speed” for ACC and TJA. I just can’t be bothered walking out to the car and reading the manual.
