Active Cruise Control with Stop/Go question

[SameGuy]

That sucks. Maybe there’s a software change that could fix this because, well, it’s dumb. If the car’s speed is unchanged, there is absolutely no need for the brake lights to be coming on. How does it work on every other car other than my Subaru?

Totally agree, I was looking through Bimmercode the other day but unless there are advanced settings I do not know about, we will look like 2-footed drivers. In the perfect world, the brake lights came on when in high regen, not low. Low regen is no different than mild downshift in a stick car and the brake lights don't turn on then.

I'm still not convinced that the lights are triggered solely by the charging. My chief mechanic believes the trigger is an accelerometer, which may also trigger the charging. And if the speed is unchanged, there won't be any regen.

That’s exactly what I’m on about. If there’s no deceleration (or reduction of velocity, or an increase in the rate of reduction of velocity), the brake lights shouldn’t light. Ok, I think I’ve beaten this dead horse enough.

I am skeptical of the accelerometer theory. My brake lights still illuminate when the needle enters the regen zone at very slow speeds (slowly creeping up to a stop sign in my low speed limit neighborhood), with negligible amounts of negative acceleration.

I'm sure that accelerometers can be very sensitive. My chief mechanic told me this after he had been to a week-long training session for working on the SE. He took me on my demo drive (and we then compared the drive with one in a Countryman JCW).

I have doubts about an accelerometer triggering the lights on the SE. Our previous Volt and current Kia have the G sensing lights, only activating with noticable regen or deceleration. The SE will trigger with the slightest regen with zero deceleration... at least from our experience.

It's a bit frustrating knowing the lights are frequently flashing, especially in our hilly terrain. Though I adapted towards feeling for that "coasting sweet spot" without eyeballing the gauge frequently, at least after a few thousand miles. All bets are off with cruise control.

.... still, if anyone knows of a software fix, I'm all ears.

AND it won't activate the brake lights under any amount of deceleration when not in regen.

This is the way.

Had my first of the oft-reported ACC shutdowns early Saturday morning (before dawn): as I descended the back side of an overpass, ACC “saw” an overhead pair of red traffic lights two intersections away and flagged off. The behavior repeated at the same time early Sunday morning at the same location.

No, Subarus (and other brands, I’m sure) offer the follow-distance controls on the steering wheel just like the ACC on the MINI; you can delve into the Subaru’s settings (using the silly paddles beneath the left spoke on the wheel) to adjust the rate of acceleration upon resumption of cruise.

Thanks for this! I have a 2015 Legacy and would love to adjust this. Although on balance the active cruise in the Subaru is my favorite (primarily comparing to ‘19 Honda Odyssey and Tesla model 3, plus a few rentals), especially in how it doesn’t panic brake at shadows and reacts quickly to lane changes. How does the MINI’s system compare to the Subaru’s overall?
