Eco Asisst

Finally, I see some new vehicle management system in the new Honda Insight. Eco Assist. I wonder how effective is this.

Besides morning start up, I find that the Civic Hybrid "drinks" the most during acceleration from rest. I have always wondered at what rate of acceleration is best to obtain the highest mpg. For example, accelerate too fast, the mpg is extremely low, but will reach the target cruising speed quicker. On the other hand, accelerate slowly may give a higher mpg, but reaching the cruising speed slower.

It would be nice if the Eco Assist manage this effectively even if drivers floor the accelerator.

Re: Eco Asisst

I have wondered the same thing as well. I try to keep the RPMs at 3000 rpm until I reach cruising speed when possible. In the city, I just try to read the traffic situation far enough ahead to minimize my acceleration needs and maximize my glide.

I think I found the answer here

on tip 9 and 14

Quote:

The Assist/Regen Gauge. This gauge will help us assess the use or creation of electric energy stored in the battery pack. The key to greater fuel economy is to keep the electric assists as low as possible and to reduce the number of Regen bars when stopping. This approach may appear counter-intuitive for many new owners but it represents the single most important factor in helping calibrate one’s foot whether accelerating or decelerating

like, keeping the rpms way below 2000???

Re: Eco Asisst

Daily driving, I try to keep it around 2000, and cap it at 2500 (the electric motor's max torque is somewhere around 2650), but if the situation calls for WOT, it's done.

Re: Eco Asisst

I tend to use the i MPG meter more than the RPM meter (or for that matter - any other meters) to achieve better mileage.

For example, if I accelerate at say 10 MPG for 10 seconds, I may try driving (cruising) at more than 75 MPG for 10 seconds to compensate for the low MPG. So on average, I would achieve (10+75)/2 = 42.5 MPG for the 20 overall seconds.

Of course, this also depends on traffic and terrain conditions.
