Adaptive cruise control question

Post by JohnSais » Fri Jun 14, 2019 11:13 am

I have found an annoying niggle in an otherwise perfect system. When using adaptive cruise control and coming up behind a car, which then pulls over to let me pass, the car will match the speed of the car in the inner lane until I have passed it, then accelerates away. This is especially annoying if the car on the inside has to brake, as this can cause my car to brake too! Has anyone else noticed this, and is there any way to overcome it, apart from pulling out into the next lane and putting the other car out of sight of the sensors?
Apart from this the system is incredibly good and makes long trips a whole lot less stressful.

I never noticed it with my Golf GTi and so far haven't noticed it on the Tig. The ACC on my new Tig is much better than the Golf, Its a lot smoother and not as harsh breaking when coming to a stop in traffic. Maybe this is a new thing that i haven't noticed yet. I'll have a look.

I would say just override it with the accelerator and once past let it do it's job again.

I have noticed it when the car in front is moving off onto the slip road and I start to pass. Sometimes my car will hesitate and slow down. I just override with the accelerator.

I have ACC on both my Tig and Passat and yes you have to use the accelerator to override this feature

I agree with the others that this is how it works, and I, too, just accelerate.

I also occasionally find the car slowing down when a car in front moves over to the right (UK) to overtake the car in front of it, and the system suddenly sees a car appear in the next lane and brakes.

Clearly, fully autonomous driving has a long way to go, and will probably only ever work when ALL cars are autonomous, and can 'talk' to each other and so predict movement rather than just react. So, not in my lifetime!

It can do some scary things on its own

I frequently use this function. It is rare but does happen, that traffic in adjoining lanes cause the car to slow. If it does happen i usually get a display between the dials as to what might happen.

I noticed that when my car detects a vehicle in the left lane it is nearly always when both are in a right hand change of direction, a very shallow right hander is the worst, it happened yesterday, a B Double semi in the right lane well into the bend and I was entering the bend and the big red light came on. I instantly nailed the throttle and the warning went away very quickly. As for the vehicle moving over scenario I can't say I have found that to be a problem but that could be influenced by distance settings so a play with them might change things. I have mine set to the shortest possible distance.
