(UN)Intelligent Cruise Control
(UN)Intelligent Adaptive Cruise
The cruise control in our new Corsair can be configured to be in one of three modes: Normal, Adaptive, and Intelligent.
Intelligent mode sounds like it should be pretty nifty. After all, it detects speed limit signs (and maybe/maybenot also uses map data) to determine the current speed limit, and sets the cruise control speed to that +/- a user-specified tolerance, which could be as high as 20 mph over the limit.
The first issue with this is that what's a good number for tolerance under one condition isn't necessarily a good number for others. For example, one might be of a mind to set the tolerance to +10 or more to try to keep up with traffic on I-95, while using 0 to +5 on a more local road. It would be useful to have a rocker switch (like the cabin temp ones) to change tolerance, but there isn't one. Instead, to change tolerance, here's what the manual says:
1. Select Settings. See Settings (page 468).
2. Select Driver Assist.
3. Select Cruise Control.
4. Select Tolerance.
5. Use + and - to set the tolerance.
So, if you do any local driving where cruise control is useful for its traffic jam assist, you probably want a pretty low setting for tolerance. Especially if you don't want the cruise taking you to speed limit +10 when the slow car in front of you turns off.
You'd think that you could just keep the tolerance low, and when appropriate just set the speed higher yourself. Well, you can. But, if you are in intelligent mode, and you use the speed+ button to increase your speed above the car's calculated value (detected speed limit +/- tolerance) the speed limit sign next to the speedometer will constantly flash until the car is once again happy with your speed.
After a short trial with the so-called intelligent mode, I've switched back to adaptive for now. Perhaps someday someone will identify which bit to flip with forscan to turn off the "too fast" blinking speed limit nag sign.
I suppose intelligent mode would be useful for someone who would never even think about exceeding the posted limit, although even they might be frustrated by the system detecting 15 mph school zone signs outside the hours they are in effect.
