Super ECO mode ideas

Now we know we have the ECO mode, which apart for re-mapping the gas pedal response, only really modifies 2 strategies for improving fuel economy - a) lowers maximum output of compressor (reducing battery draw) and b) lowers engine temperature threshold for engine on when in EV region of HSI, (reducing engine on time). Fan speed is also reduced for both strategies.

For Super ECO mode, here are some possible ideas I was thinking about for a "Super ECO Mode" with the understanding that it would be for those willing to endure a little more sacrifice.

So when in "Super ECO mode" the following strategies are set.

-Releasing gas pedal allows a glide (no regen fake drag)
-Heat auto switches off when coolant temperature drops to 51 C and HSI is not in "engine on" region, and auto switches on when HSI is back in "engine on"
-During regen braking, electric seat heat is maximized or max A/C cooling is implemented, depending on car temperature, and when regen stops, is set back to much lower output. (Rear and side mirror heaters should also auto swicth on to absorb the excess regen power)
- Cruise control cannot allow HSI to go beyond middle of PWR region, or go into low load region of HSI
-Instant off of engine once engine temp reaches 51 C, regardless of vehicle speed, when foot is off gas
- Remove hysteresis effect that requires gas pedal to be fully released for engine to go off
- Tire inflation warning comes on at higher pressure threshold
- Less power assistance provided to electric steering
- Modify traction battery SOC algorithm to depend more on the engine for acceleration

 

Of course no regen would be best, except for the typical driver behind me, honking at me wondering why I did a 30 second glide to the one of sixty or so stops I encounter everyday. But for the conservatively 95%+ of drivers that do at least some regen, it is more efficient to have the generated power used right away as it's generated rather than after it's gone through the losses of charging and discharging the traction battery. Of course if the regen roundtrip losses could be reduced substantially, it would benefit the more average driver more. Not sure if Toyota has looked into Super Caps to capture the sudden blips of regen, or a small version of a flywheel energy recovery system connected to the rear wheels would capture the excess energy that the HSD doesn't capture.
The goal here with Super ECO mode is that it would give the average (non-expert) driver an efficiency improvement - The expert Prius driver looking for max efficiency probably already doesn't use CC, and turns off the heat at extended red light stops, puts the A/C on full output when going down a longer decline in steeper terrain in summer, and doesn't use their seat warmers or rear defrost.

It's a pity Google maps or other providers don't have stop sign data, or traffic light data showing the % of time the light is green for a given travel direction, and speed limit data, as it could help optimize the best route for both hybrid and non-hybrid drivers. It's also a pity that many city's put 4 way stops in places that could have 2 way stops or even 2 way Yield signs so one can do a rolling stop.
