Reduce aggressive braking when autopilot or TACC is engaged by increasing the stopping distance.
This is similar to the Chill feature provided by reducing sudden acceleration.
We’re going to close this one out as implemented. The braking today (June-2021) is quite smooth as compared to years ago when this was created. In addition, you can set the following distance further away to act as a “Chill” mode.
First, I think we all follow too closely, whether driving manually or selecting a distance setting with an adaptive cruise control. You will get a lot more smoothness in both deceleration and acceleration if you just move that number from a 2 to a 5. Also I have found it a great idea to actively change the following distance setting as the situation unfolds.
Having said that, there are still situations where the AP could do better. When you are in the right lane or next preparing for an exit, you often will have traffic accelerating and merging in from the right ahead of you. I like the idea of the AP detecting a turn signal from a car in an adjacent lane that would bring it into yours, and moving slowly back before the car actually starts changing lanes.
AP1 is an example of well behaved autopilot. AP2 never achieved the smooth acceleration/braking of AP1. AP2 also is more apt to use ABS, which pumps the brakes and causes a shuddering noise during aggressive braking. I keep the distance setting to five or more to avoid the noise.
