I could swear the HCH has one, too. Keeping my foot absolutely still, I swear the car will kick in a little assist and/or increase RPMs if a hill I am going up suddenly gets steeper. I have trained myself pretty thoroughly to drive with the load, so I'm keeping my right foot absolutely still up most of these hills. I realize this is a HAH forum, but have any other HCH pilots noticed this phenomenon? Am I making this up?

Now that you mentioned that, I've seen the same thing in the HAH. But, instead of driving with 'manual' speed control, I use the CC. As I approach my radar site, there's a very slight incline. But, the HAH, will show a few bars of blue just as I go up it. Don't know if it's related to the vehicle speed dropping, or that the car senses the incline and starts to compensate.

Okay, where are our Honda techies? Care to shed some light? Now I am even MORE curious!

In the HAH, it's a programmed process called Grade Logic Control and it senses when the car is climbing or descending a hill and eliminates "gear hunting". See and play the Flash demo that fully explains how it works here: http://automobiles.honda.com/models/...=Accord+Hybrid

Speaking of CC, has anyone noticed that the CC in the HAH actually starts working at 25 miles per hour? Most other CC implementations I've seen only start at 40 miles per hour. Makes me think that the Honda Engineers intend for us to use the CC for most of our driving.

Every car with cruise control I've ever driven starts at 25 miles per hour.
