Charge / Save / default

IMHO "non deterministic" and "fuzzy" are both different wordings for "not fully understood". Does randomness really exist, or is the order in which events happen so complex that we do not understand it? Or do we simply fail to appreciate one or two parameters? :mrgreen:

I think they're firing up the Large Hadron Collider soon. Perhaps that'll help?

Well, you certainly can argue that anything implemented in a computer is ultimately deterministic, but Fuzzy Logic is a well developed approach to control systems and implements systems in a way that is difficult to analyse deterministically. You can certainly see a PHEV (and a Prius, for that matter) apparently behaving in significantly different ways under apparently identical conditions at different times. I have a moderately steep hill to climb a short distance from my house and usually approach it with a almost fully charged battery. On successive days under what would appear to be identical conditions, I can find the car cruising up it with the engine little more than ticking over one day and screaming its way up with the engine revving hard another day. I'm sure it is down to how hard I'm accelerating as I start the climb and how fast I'm going in the first few yards, but once it decides to push the revs up high, nothing is going to convince it to go back to a gentle ascent.

Equally, I'm pretty sure that the strategy you discovered recently to force it to charge quickly under engine power is exploiting some quirk in the control systems. No Mitsubishi programmer sat there thinking "now, I'll put in the code to catch a momentary cancellation of Cruise Control while the regen braking is set in this way and interpret that as GO INTO FAST CHARGE MODE". This is the sort of behaviour that is often associated with fuzzy control systems - some unexpected factor can make it flip between two significantly different patterns of behaviour.

This is a monster that my travels away from a computer made me miss.

As only one of a known 2 PHEV's that can now default power ON in SAVE, or CHARGE mode, I have 5000+ km of my PHEV default power ON, in SAVE mode.

In the 5000 or so km, the PHEV generally maintained over 50%SOC with only 2 overnight top ups of corded electricity and one CHARGE mode to 3/4 following full depletion to reach a refuel stop with almost empty petrol tank.

If the road conditions demand high power needs and the PHEV is powered OFF before a chance to replace battery SOC, then the stored energy does deplete.

All PHEV owners who drive a mix of long and short trips, or towing needs would benefit from a default power ON of not just NORMAL mode. The drivers only doing short trips probably would not benefit.

My drives seem to favour the deferred use of the battery, or controlled use of the battery, so I benefit greatly from my PHEV powering ON in SAVE mode. Not having to remember to press a button is so good. Battery is depleted very quickly at highway speeds.

RE my driving lights. Yes they do provide excellent night time driving vision. Over 4km for road signs and cats eyes on a straight road. Only use spot lights away from towns and traffic. I can select which lights are ON, and they only work with the high beam. City and town driving are not real different to a std PHEV. I just have only white light, and no yellow. Animals are very easy to see in white light, and I much prefer to drive past an animal slowly, having seen it and taken action rather than saying "That was close", having whizzed past a kangaroo having not seen it, as had happened before I upgraded.

Hello! How can be SAVE mode made default? Thanks!

It can't.

Neither would you want it to be when you start off with a full battery as there'd be nowhere for your regen to go.
