Traffic Jam Assist

**latearrival** · 08-03-2017, 10:37 AM

I don't have my Tig yet either, so I could be talking out of my backside. But here's what someone else posted from the UK manual:

Traffic Jam Assist function
At speeds under 60 km/h (35 mph) Traffic Jam Assist can maintain a time interval, set by the driver, to a vehicle in front, and help the vehicle to stay in lane. The system automatically controls acceleration, braking, steering and, if required, will decelerate to a stop behind a vehicle that is stopping, and then drive away again automatically.

Adaptive Lane Guidance
Activating or deactivating adaptive lane guidance, the lane keeping system does not just provide assistance when the vehicle is at risk of leaving the lane. If the system detects both lane markings to the left and right of the vehicle, the function provides permanent assistance while the vehicle is in motion. The system adopts the preferred position within the lane in which the vehicle is travelling. For example, if the vehicle is being driven slightly off-centre in the lane, the system will learn to adopt the new position within a short period of time.

EDIT - @TungstenR from NZ said his Tig has TJA & ALG

Has he ever commented on his experience with it? Do you know of any comments of users with TJA?

I think you're right. The handbook does call it Active Lane Assist. I assume the "Active" bit means it actively controls the steering. But only to bounce you off the lane markings. It's still the poor cousin to the Adaptive Lane Guidance, which is also needed for TJA.

No to both. But I just sent TungstenR a message and asked.

IIRC and this is a big maybe, am I correct in thinking that TJA is not standard fit in the UK but either comes with certain models or is an option requiring spending money to get it?

Sorry, I have no idea. Perhaps someone else can chime in?

OK, the experience... Considering TJA,...nada, as I don't live in a congested area. Considering Adaptive Lane Assist, that's a different story, almost nada too however, but I must explain;

the vehicle data sheet says I have
- lane change assist and lane keeping system, code 7Y5 SPU
and
- Adaptive cruise control (with "follow to stop") and speed limiter, code 8T8 GRA
and
- Lane change system Side assist Plus incl. lane keeping system Lane Assist (ROW), code PSL

I see all this information in the Head Up Display, complete with the pictures for "Adaptive Lane Assist" as explained in the car manual, but in actual drive I feel a gentle push when driving towards any of the lines, not for staying in the middle of the lane.

I've had a few electronic issues though, out of the blue 1. emergency assist once displayed it was not available, 2. ABS once displayed it was not available (when the car was at the dealer, but they could not find what was at fault), 3. during a long drive the display suddenly said that lane assist wasn't available, and indeed it showed as being de-activated in my HUD. After we stopped, and re-started, everything seemed OK again.

When I have time they'll have a look at it at the dealership...

Thanks for taking the time to share your experience. Unless your car has been misconfigured, it's beginning to sound like NZ doesn't get Adaptive Lane Guidance (and therefore TJA) after all. Perhaps the only thing NZ gets that Australia doesn't is the HUD.
