oh, just the basic gauge indicator on the dash.   

 

seems like when it shows about 20% left on the dash it will hardly allow any pedal pressure without the engine starting.   My thought at first was that in cooler temperatures the car (even with hvac off) knows that the battery is super low, so it might as well turn engine on to get temperature up even without a demand for more power.    But that doesn't jive with the noted sequence above or efficiency.

Smart Gauge 20% = ScanGauge II 38% approx. ;)  In normal use EV works between 38% and 50%, you go much above that and EV assist comes on. :)

If I understand correctly, in S1a the ICE is not supposed to power the wheels. However, in my car this doesn't seem to be the case. Immediately after a cold start my Engage screen shows that the ICE is driving the wheels, and the upper arrow above the battery gauge is displayed while the car is moving.

The electric motor drives the wheels if I happen to be reversing, but as soon as I switch to D the blue bar disappears, and the ICE takes over.

Maybe there was a change in the algorithm in the meantime? Could the latest models be programmed differently? Or am I missing anything?

It is physically impossible for the ICE to move the car in reverse.

 

If the HVB charge level is too low then the ICE must be used.  They will never let the HVB get below a minimum level.  The HVB is what starts the ICE.  If the HVB got discharged the car would be dead since there would be no way to start the ICE.

Don't get too carried away with all of this. All of those states (S1a, for instance) are from Toyota documentation. Our Camry Hybrid and Fusion Hybrid are programmed completely different even though the basic design of the engine/drive train are the same!
