Understanding Cruise Control

Actually, I believe this is tech is quite old now.
We've been talking about driverless cars. Wait, there ARE driverless cars, that are running just fine.

Anyways, coming to the topic, this post explains it beautifully: http://www.team-bhp.com/forum/techni...ml#post3476176

I think the correct terminology is Adaptive Cruise Control.
I think vagtune offers retrofit of ACC in VW cars like Passat and Jetta that don't get the feature as standard in india.

Adaptive Cruise Control has been around for a while along with features like lane departure warning, steering hold reminder, speed limit warning identifier, etc. However these are not really useful in the few cars available in India as they depend heavily on the traffic patters, uniform lane markings, uniform road signage's all through the camera.

So hoping to use such a system reliably in India is still a distant dream. What exactly is the point of this thread?

It is indeed Adaptive Cruise Control. Even with most advanced version of ACC, it is not automatic driving as car cannot turn or take diversions on it's own.
ACC has been around for fairly long time though it's been constantly improving. I have been using such cars on and off for a while now here in Netherlands. There are many flavours of how it usually works. Most cars with ACC will have a way to manually adjust the distance between the car and vehicle in front while cruising. Most advanced ones can deal anything from stop and go traffic to 150+ Kmph. Lesser advanced ones can do cruising above a certain speed limit, but goes off automatically when speed goes below a certain limit. Having automatic shift makes it more meaningful as otherwise the level of automation and range to what ACC can operate gets limited.

Here is a demo video.

Here is a video by Ford showing Adaptive Cruise control:

Basically, ACC uses radar sensors which detect the vehicle in front and mantain a safe distance and brake within the distance.

Here is a detailed Wikipedia article about Adaptive Cruise Control:

I use ACC very often in my car. In the Indian context, I think owners need to keep a couple of things in mind when trying ACC for the first time. First, ACC maintains about 2-3 car lengths distance to the car in front, especially at highway speeds. In Indian traffic, this is an open invitation to others to barge in and occupy the space. Secondly, once someone has barged in, ACC slows the car down to maintain a lower speed due to reduced distance to the car in front. This might catch the guy behind off guard, if he is following too close behind.
