Your concern is valid. I worked with programming hybrids and I did it like this: Engage ICE until operating temperature. Allow auto-turning it off for EM only.

Your concern is valid. I worked with programming hybrids and I did it like this:
Engage ICE until operating temperature. Allow auto-turning it off for EM only. Hysteresis to like 2/3 operating temperature.
There is a "force electric" button for like a short ride on all EM.
The reason was to keep engine wear down as well as emission demands.
- WirelessGigabit 4y agoOkay so you started to drive, on ICE + EM. When ICE is on temp you allow auto-turning off. When engine fell back to 2/3 of operating temp you went back to mandating the ICE to remain on. Did I get that correct?
- rightbyte 4y agoYes. 2/3 is not exact but kinda from distant memory. Was plenty of factors. Of which emission control was the most "annoying" when optimizing for fuel consumption with the hybrid strategy. It was heavy vehicles, so dunno if car engines need different long term temperature operating ranges.
