Replying to: dunwoody (Jun 10, 2006 12:21 pm) I no longer try consciously to avoid the ICE kicking in. I just avoid hard acceleration and braking (a difficult task at times in NYC). I get 19-21mpg on 5 minute trips in the neighborhood. On the highway I get 29-32mpg. What I would like is more battery power so I could run longer on electric. |

Replying to: nomorebenz (Jun 10, 2006 4:19 pm) The best is still to recharge by coasting and coasting in "B" mode if at all possible. When coasting and coasting in B mode are difficult, we beliberately blend full-electric run with low-speed (25-35) ICE-assisted run if possible. This is so we recharge the batteries every time it drops to four bars. It seems four bars is the minimum meaningful threshold on our HH. Over four bars of charge, our HH can easily run on full-electric at 38-39 MPH for 1+ mile. Below four bars, it can reliably maintain 25-MPH for close to 0.5 mile before sinking to 2 bars (Pink). Maintaining four bars seems to help us run on electric more often.

Replying to: cdptrap (Jun 11, 2006 1:20 pm) I suspect it will do the same thing if you simply release the accelerator pedal and not apply the brakes. Unless, of course, the batteries are already "full".

Replying to: wwest (Jun 12, 2006 9:17 am) Unlike previous very precise Toyota Cruise control, the HH Cruise leans towards fuel-efficiency (just a guess) so it always lags a bit upon start of a climb. This always causes the engine to growl and surge to rocket the car up the grade. On a long climb, this is acceptable because there is plenty of distance and time for the computer to adjust its power so the car has room to settle back to set-speed. On a short climb like up an overpass, this surge in power easily shoots the car up to the top at over the set-speed before the computer has time to adjust. This is too dangerous when there are cars in front. So we no longer use cruise in such area. We had a close call last summer when we first got our HH. We let an impatient H2 passed us on a 1-lane rural road. It was probably doing 55 in a 45 zone and we were crusing at 45 so it zipped by and kept going. As we entered a hilly portion, there was a sharp steep climb after a sharp turn. We came around the corner, felt the HH engine kicked in and the car shot up the grade and right in front of us was the H2 grunting to climb the grade. Luckily, there was room to pass so a quick move took us pass the H2 and kept going to the top. There was little time to even think about it. The speed had surged past 45 to around 47-48 before it settle down to 45. After that experience, no more Cruise control on narrow mountain roads or freeway overpasses and we observe the 5-second (not 3-second) rule religiously. |
