Traffic Jam Assist

[Ozsko]

Can you ask the service advisor what software is needed to do this upgrade please. He likely won't know and a tech will have to provide the answers. Thanks.

Yep, I fiddled with it quite a bit. 60kph is the magic number. At least for the AU implementation... perhaps it varies from country to country according to the prevailing speed limits on urban roads?
What I did notice is in urban areas, and single lane roads, the markings are not as clearly delineated in Sydney and it freaks out and asks me to take over... intersections and turning lanes in particular.

did some playing today, at 10mph (16kph) it did in fact ask me to take over steering after 12 seconds in traffic, but if the car in front broke down to 0 then sped back up a few times it didn't seem to, in the UK it seems to be 38mph (61kph),

Yes, you are right. I’ve begun to suspect that TJA also needs to see a car in front, otherwise it asks me to take over steering under 60kph.
So that would mean 4 conditions need to be met for TJA to activate:
1. ACC on and active
2. Adaptive Lane Assist on and lanes detected
3. Following/traffic speed <60kph/38mph
4. Vehicle in front present (presumably there is a range/max distance

I must say I’m not sold on the steering assistance. It tends to wander out of the lane from time to time and freaks out the cars around me. It’s hard work for me playing chicken with the Lane Assist and not intervene... in the interest of learning the system limitations.
It seems to be geared towards avoiding serious injury accidents, and appears it would do a great job of that, but it’s not necessarily up to avoiding every bingle.
Same with the ACC breaking down to zero. A couple of instances (say, 5% of the time) it seems a little late to brake for my liking.
There’s no way you can let your attention wander... at least further than the infotainment system or AID.
What I do enjoy very much is flipping on the ACC in any traffic delays and just keeping my foot close to the brake in case. It makes traffic jams slightly more relaxing. And probably easier on the DSG clutch pack than if I was on and off the throttle/break.

Curious if others think so too...
Looking forward to hearing from the MY17 guys getting theirs enabled... fingers crosssed for you guys, good luck!

The more I see of what TJA can't do the less advantage it presents for me. When I started my campaign I presumed it totally managed the car under 60kph but it seems to me to do nothing of the sort. It does not remove the 3 second delay, the 12 second delay is still there so all it is is ACC enabled under 60kph. if it totally took over the car as I thought it should and did then I am all for it, as it stands it is hardly worth all the hoopla to get it working IMHO.

I feel the same which is why I haven’t played around more with trying to get it activated. I am hopefully going to get some scans of dmnz car before and after it gets enabled for him which we will share but I don’t see too much advantage of it at the moment.

Hi Neal

Yeah, that was my post. Didn't actually work. Thought it did, but didn't work as expected.

Back to the old drawing board.

I certainly would not knock back the opportunity to activate it but I am not going to be disappointed if that doesn't happen. They will want to do a lot better before it becomes a sought after feature by me. I am sure Bosch and VW can supply a total management traffic assist but the Bosch themselves reckon the market is not ready yet.

Just to say, I've had a car in front and no car in front of me at various speeds below 60 (3 and the car asked me to take over steering, couldn't get in a situation where the cars in front were traveling at a crawl (Tickover and couldn't recreate because minimum for cruise is 20mph) for more than a few seconds

ACC down to zero is the winning feature for me. Hitting ‘resume’ with my thumb is not a big deal when the 3 second timeout has paused ACC.
If the feature wasn’t already there, I’d probably want it... but now I already have it, it’s a bit ‘meh’.

Bosch and VW have been in the hot seat over dieselgate and are both risk averse at the moment. Recall the media frenzy when a Tesla drove under a turning truck on Level 2 autonomy.
Technically TJA is L2 (I think)...

Perhaps my next vehicle will be able to park itself neatly in my garage and meet me at the front door when paged. That’d be a good start... I also look forward to change in legislation that lets me have a couple of drinks and let the car see me home safely and legally 😂

[Ozsko]

Bosch stated their position prior to Dieselgate (why is everything "Gate"?) Anyway back on topic, if I am in a stream of traffic ACC controls the car down to zero, the steering goes away under 60kph but that is the only thing that TJA brings to the car and requires constant attention. Apart from 12 seconds of steering there is no advantage.
