Re: Anyone else notice more aggressive assist when fuel low?
I was hoping others had seen the same behavior, in part, because I would like to figure a way to cheat it into working that way all the time.
I love when I can use the assist for all the heavy work, and save the gas for just the light load of cruising. And I was getting good drivability for those miles that it was "low fuel". The only time I worry about saving the assist is when I have to climb the hill at Stony Brook Park, south of Letchworth on NY Rt. 36 southbound. Coming back, that hill can recharge the batteries from about 40% discharged (60% capacity) to full with regen cutting out just before the bottom of the hill.

If you know there is an opportunity to capture regenerative braking, it's better to be "assist-happy" as you will replenish that using braking energy, rather than trickle-charging from the engine. Likewise, if you know you will be climbing for a while, it would be better to lower the threshold for calling assist, or lower the amount of assist given at a time to 'stretch' the pack out. This is where having some sort of manual control--such as a switch between different assist algorithms built into the car--would have been a very handy feature for Honda to implement (similar to how many modern automatic transmissions have different shift algorithms the driver can choose).
as well as hurting the battery pack by over-using it.
