ICE shutdown for the FEH/MMH?
In reading about the MIMA for the Insight, and considering my own wishes for improving the FE of my Mariner Hybrid, it got me to thinking that an extremely useful "mod" would be an ICE shutdown switch/button. Not an "EV only" mode like for the Prius, rather a button that would allow me, the driver, the ability to institute an ICE shutoff in certain situations. I don't want an override, and would want the computer controls to be able to restart ICE as soon as conditions required it. I would just like the ability to instantly shutoff ICE when I know I don't need it....for example: on long downgrades where I can coast, or as I am approaching a stop sign/light, or if I am idling at a stop due to a low SOC, etc. Turning off the key isn't safe or probably legal either. Having to shift to L and tap the brakes seems like wasted steps and requires slowing down and makes drivers behind you think you are braking.
I'm just wondering if anyone out there in Hybrid land has considered such a project and/or the feasibility of doing so.
