Learn more about Porsche 911 Adaptive Cruise Control

Posted: March 24, 2021 Updated:

Porsche's Adaptive Cruise Control works at speeds below 30km / h

On this day, my Porsche 992 finally reached a mileage of 2,100km, and it was about 900km to leave the break-in.

So I went out in a good mood for some errands, saying, "I wonder if I'll run about 150km today." It's like we're in front of us.

I had no choice but to take a leisurely ride while thinking about things like "Hey, I can see Mt. Fuji from such a place" that I didn't usually notice.

On the way, it seems that there was an accident in the other side, and for a while, I passed by leisurely, and the traffic became so congested that the car might stop completely.

Then I suddenly remembered a question that was in me. The question is

"Porsche 911 Adaptive Cruise Control "Can be set at 30-210km / h"Does this mean that the car will not work or start unless it is running at speeds of 30 km / h or faster? "

That is.

In that case, if you suddenly get stuck in a traffic jam when ACC is not turned on, you will not be able to use the ACC you want to use when there is a traffic jam (unless you proceed at a speed of 30 km / h or more).

I decided to take this opportunity to try it, "Isn't that supposed to be the case?"

Here, when ACC is OFF, I got stuck in a traffic jam, and the speed of the car is 0 km / h and it is completely stopped ↓

In this state ... I pressed the ACC switch ...

a! It's turned on!

I was able to turn on the adaptive cruise control function even when the car was completely stopped.

Next, try setting the running speed while it is stopped.

Click.

Ah.

So that's it! !!

You may have already understood this, but I was completely misunderstood / misunderstood.

This "ACC is 30-210km / h" means "the speed you want to drive is 30-210km, which can be set as the speed to drive"!

In other words, ACC "functions (can be turned on)" regardless of whether it is 0 km / h or 300 km / h. However, the running speed setting that can be set at that time is in the range of 30 to 210 km.

Haha ~.

Therefore, even when ACC was turned on and the speed was set at this full stop, the speed displayed first was "30 km".

When I tried to understand it in this way, I was talking about "it is natural", but I completely misunderstood the explanation of the ACC setting, so at this time it was a one-person car. I was impressed with "Ah !!!! That's it !!!!"

It's embarrassing because the level of emotion is always low.

What is Traffic Jam Assist?

One more question I had about this adaptive cruise control.

There were two ACC options, just "ACC" and this "ACC with traffic jam assist".

I'm not sure what it is, but I thought it would be better to have it, so I decided to use it with traffic jam assist, but I didn't really know what this function was.

I always research Porsche about car options that I don't buy, but when I actually buy it, I don't care about it (laughs).

When I looked it up, it was explained as follows ↓

What is Traffic Jam Assist?:
A function that the adaptive cruise control system automatically starts and stops the car even in heavy traffic.

I see.

So, I also experienced this.

While looking at my 992 in the car in front of me and thinking "Oh, it's cute" (I don't need this information (laughs)), I'm trying ACC on a general road during heavy traffic.

When I tried it, depending on the driving situation of the car in front, I followed the car in front at a slow speed of "almost this, creep", or if the car in front stopped completely, 992 is also automatic It stopped completely at.

And it's an automatic return after a stop, but it feels like I've tried:

  • If the time when the car was completely stopped is short, if the car in front restarts, it will automatically restart and follow the front without doing anything with 992.
  • If the time when the car was completely stopped becomes longer to some extent, the 992 will not move even if the car in front restarts. So, if you step on the accelerator a little, the 992 will continue ACC as it is (even if you do not mess with anything) with the feeling that "Oh, sorry, I slept a little" and follow the car in front. Become

★ Addition (2022.2.28) ★

Differences between Adaptive Cruise Control (ACC) and ACC Traffic Jam Assist

I have investigated it a little more, so I would like to add it.

In the case of just adaptive cruise control, if the vehicle in front stops, your car will also stop. Then, when you want to start running again, lightly step on the accelerator and ACC will resume while maintaining the set speed and distance.

If it is with ACC Traffic Jam Assist, it is the same until your car stops when the vehicle in front stops, but the movement after that is a little different."If the stop time is within 15 seconds, it will automatically restart when the vehicle in front starts running."To do.

If the "stop time is 15 seconds or more", ACC will be restarted by lightly stepping on the accelerator as with normal ACC.

In other words, this traffic jam assist is that "when the time that is automatically stopped during ACC is within 15 seconds, it will stop and go without permission".

Assisting traffic jams that stop and run just a little ^^

Here is a Porsche video explaining that (official).(Video around 3:25)

On this day, I knew that I could start using the adaptive cruise control function even at full stop and what traffic jam assist was, so it was very refreshing ^ ^

Moreover ~.

After refreshing, after all the scenery when running with ACC in a sloppy driving is Porsche ~ ↓

With ACC, I was able to drive while looking at the Porsche in front of me leisurely (rather than driving everything myself), which was also good.

Before ordering 992

"It's impossible to use ACC with Porsche 911! I never use it, so I don't need it."

I used to say that, but when I tried using it, it was so convenient that I couldn't stop (laughs). I use it frequently when it's crowded ^^
