Traffic Jam Assist

Ozsko, I have a 132 Comfortline with DAP and yes, it has "active lane assist" but not TJA. Dissapointed but there you go

Does your Tig keep itself in the middle of the lane without any steering input from you? Or does it only take control of the steering when it notices you about to cross a lane without indicating?

If it has active lane assist it will have TJA from what I know. If it actually says active lane assist on the menu selection item and not simply lane assist I would think the spec of the vehicle is a mistake on someones part. I only say that as no one else seems to have it on any spec of vehicle in Oz. Does it have ACC, if it doesn't that would be a show stopper.

Well it's active in that it steers back in the lane...but you are correct in VW speak it's only ACC.

As I understand it (but I'm wrong more often than I'm right!) ACC just speeds up or slows down the car to maintain the distance between you and the car in front. It does not do any steering.

ACC needs to be functioning in conjunction with active lane assist (guidance) for TJA to work. ACC starts/stops/controls the distance to the car in front and ALA or guidance steers the car and positions it in the lane and between the two they totally control the car under 37KPH with no input from the driver. Without any additional first hand user information from an owner who has actually used it that is my understanding. For some curious reason I don't understand there has been very little comment or user experience on this forum and there must be quite a few cars out there with it fitted. The only reason I can think of for no comment is people simply do not use it or are possibly aware it is there and how it functions.

I don't think what you've said is right. There's a whole thread on this somewhere. I'll find it in a minute. For TJA to work ACC needs to be functioning in conjunction with Adaptive Lane Guidance

EDIT - Some discussion of this in this thread, from Post 35 onwards.

Just steers back into the lane if you touch the line. Still a very useful feature IMHO

I've found the terminology for the safety tech across models really confusing. To have TJA, the car has to have Adaptive Lane Guidance, which the UK and NZ models have but not the Aussie. ALG keeps you in the centre of your lane in the freeway. As you said, Active Lane Assist just 'bounces' you off the lane markings.

Let me clear up something, I haven't seen a car with these features so my terminology might be incorrect, note the brackets in my previous post. I might be wrong but in the handbook it calls it "active lane assist", I will check later. The emphasis in either case is the "Active".
