So I'm a little confused. I was aware of a feature called Traffic Jam Assist that's available in Passats. It's described in this video:
https://www.youtube.com/watch?v=O2jAwRAXu6Q
I think it's awesome, I sit in a stretch of bumper to bumper traffic every morning (literally only moving every few minutes, and gaining about 20 meters each movement) . It takes about 20 minutes to get through a particular intersection.
That feature isn't listed in VW's glossary though: Technical glossary < Volkswagen Technology & Service | VW Australia (http://www.volkswagen.com.au/en/technology_and_service/technical-glossary.html)
The latest Volkswagen magazine describes the following in the new Tiguan article (page 13): "Volkswagen's latest Adaptive Cruise Control (ACC) system is an optional extra that can help take the frustration our of stop-start traffic. It works in league with an improved Lane Assist feature that can steer errant cars back onto the right path." Now, the way they describe that in the first sentence sounds a lot like Traffic Jam Assist, which I've always pictured as a combination between ACC and Lane Assist (i.e. maintain a distance between the car in front, and automatically steer the wheel to stay within the lane)."
Anyone know if that actually translates to the traffic jam assist feature? I thought ACC only worked over certain speeds like traditional cruise control, but according to the glossary "brake intervention takes place, braking the vehicle to a standstill if the traffic situation necessitates ". Although, the Lane Assist feature apparently doesn't activate vehicle speed of less than 65km/h.
From the glossary:
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 in a speed range set by the driver. If the vehicle 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 vehicle 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 (Automatic Models).
Lane Assist:
Lane Assist is a lane departure warning system that is designed to help reduce the likelihood of the vehicle leaving the road or crossing into an oncoming lane and therefore the risk of accident as a result of driver distraction or a lapse in concentration. The Lane Assist system monitors the road ahead with the aid of a camera (located near the interior rear-view mirror) which recognises lane markings and evaluates the position of the vehicle. If the vehicle starts to leave the lane, the Lane Assist system takes corrective steering action or vibration depending on model. If this is not sufficient the driver is warned about the situation by a steering vibration and is asked to take over the steering. Additionally, if no active steering movements by the driver are recognised for longer than approximately 8 seconds, a message will appear in the Multi-Function Display in conjunction with a warning tone. The corrective steering function can be overridden by the driver at any time and the system does not react if the turn indicator is set before crossing a lane marking. Lane Assist cannot replace the driver’s attentiveness. The driver is still legally responsible for the vehicle and therefore staying in the lane at all times. The system will not work if there are no recognisable lane markings. The camera vision can be reduced by rain, snow, heavy spray or oncoming lights. This and vehicles in front of you can lead to the lane markings not being recognised by the Lane Assist system. The Lane Assist system does not activate at a vehicle speed of less than 65km/h.
