Standard cruise control

[f1eng]

I see quite a few posts recommending adaptive cruise or Innodrive.

I didn’t like the way, and when, adaptive cruise took control of my Prius and had for decades used a normal cruise control and got used to disengaging it when necessary. I like to travel at a steady speed so I didn’t specify ACC on my Taycan and on the few motorway trips I have taken was delighted to be back to “normal” for me.

While my Taycan is broken I have used the Prius for a motorway journey and again hated adaptive cruise and ended up not using it because even in fairly light traffic it slowed too early and travelling at a steady speed was impossible.

Mind you I again noticed a string of cars hogging the centre lane all speeding up and slowing down in tandem, so I suppose a lot of people use it but it makes driving in the correct lane and cruising at steady speed quite difficult.

So I not only dislike it myself I dislike others using it…

I’m totally with you on this @f1eng ! I could never understand why Porsche’s ACC system was not designed to enable you to run it in active or passive modes but this is exactly why I don’t want it either.

Even the best forum members aren't right all the time.

I'd be lost without ACC (and Active Lane Keep) on my long road-trips. It works remarkably well – using the Audi zFAS technology (sensor fusion) to combine inputs from the radar, camera and ultrasonic sensors to build up a picture of the environment around the car.

You can control the distance between you and the car in front and it will slow you down to a halt in stop-and-go traffic.

One of my favourite features, is the little triangle it places on the speedometer to tell you the speed of the vehicle in front. Even if you aren't using ACC, its really useful to be able to tell that – so you know if you should match them or plan on overtaking.

In heavy rain and/or fog – the radar is an additional aid to keep you back from cars in front even when visibility is very poor.

Nothing is perfect – and I'm sure they are more sophisticated ACC systems out there – but it has become a must have feature for me in a road-trippin' Porsche.

For me the only time it isn’t a PITA is in very heavy traffic with stop-go traffic jams.

I do my best to never use a route where they may be possible, not always successfully.

Generally I find having the driving taken over from me disconcerting and stressfull.

It works for me and on particularly long journeys it is far more relaxing. The only gripe i have is when people cut across you forcing probably a more dramatic response reaction, than what a driver controlled response might be, i.e. a more blended response, perhaps even without any braking intervention.

When it comes to stop-start traffic (increasingly everywhere) it also manages the whole process without any need to interfere in accelerating/braking, other than a nudge on the stalk if you have been stopped for a while.

Finally and I don't know if this applies to the normal cruise control but with ACC it also recognizes speed limit changes and adjusts accordingly. That's also pretty useful on longer journeys. For anything other than longer journeys its all irrelevant...

Personally, I didn't like InnoDrive when trying it. It decelerated and accelerated in ways I was somewhat uncomfortable with, and I did not always feel sure that it would "brake" in time. I feel much better doing these adjustments myself, the right foot isn't overly occupied anyway. Accelerating just the way I like it is also one of the enjoyable aspects of driving.

I did include ACC and use it from time to time on long journeys when the right foot can make use of a break (it happens), and it was worth the money for this I think. But driving feels more like transport then.

Active Lane Keeping I regard in quite the same way. As long as I drive (and am not merely being transported), steering is not a bother but part of the enjoyment.

Exactly.

I find normal cruise control best for long journeys. The adaptive seems to never get it right unless, I suppose, one joins the peloton of cars hogging the centre lane of the motorway.
I had normal cruise on cars for 30+ years and my first experience of an adaptive system was a disappointment.

Maybe I argue against myself (in other contexts) now, but when I use ACC I think of it as standard cruise control with the added safety feature of helping avoiding cars ahead of me. I don't expect more from it than that.

This could open up for the argument that ALK hinders me in leaving my lane. But when I tried ALK it felt rather intrusive (I don't remember the details now), while ACC is not intrusive until it has a job to do. This way of arguing makes sense in my head, at least.

I do like ACC. More on B roads than on the highway. On the highway I would probably rather drive with CC like you describe.

second reason I always have it is the long distance radar for emergency braking. It saved me twice last 5 years in two different cars. Should have been more attentive my self of course.

I agree with @tigerbalm and use ACC a lot on long road trips. Very useful also on German autobahns, where it detects changes in speed quite early. It is not as smooth as human input when catching up to slower traffic etc, but overall one of the better systems I have tried.

I have the full Innodrive, but have switched off the automatic speed settings. That has a lot of flaws, reads the incorrect speed signs, incorrect speed data in the map data, unworkable after short term road works etc. And can adapt abruptly to a lower speed when it reads off a side road! Dangerous!

Easy to use to do a manual confirmation for adapting speed if needed.

Even my son found it extremely useful in the stop and go traffic into Silverstone for the race weekend. The traffic was quite heavy.

But with so many other things in life it is a personal preference

I quite like it for the reasons others give above. But I would like to be able to revert to standard cruise control in some settings - however I don’t think this is possible. If it is, please post how! The nearest you can do is reduce the distance to the car in front down to the minimum. The biggest annoyance is the over reaction it produces when someone cuts in

 

[jonjon808]

The other feature that I like is the dynamic speed limiter, particularly for UK roads where the speed limit change change without apparent change in road circumstance. If you're just about 60 mph on a great bit of road and don't spot it has reduced to 40 you can be in trouble. Still disconcerting that the car will slow itself down to 40 though

I've only used ACC on a long road trip since I don't have a daily commute but found it to be great. For those that want it to act like normal cruise control on occasion, doesn't using the pause/ resume feature accomplish that?

When traveling at high speeds, I increased the follow distance and in stop and go traffic, I used the closest setting. Changing lanes in traffic can cause a surge and getting cut off can result in abrupt braking, but once you figure those scenarios out and use pause/ resume, I think the safety benefit of ACC is well worth it.
