Hybrid vehicle edification?
Posted by: RAMd®d

It's my base understanding that most if not all hybrid electric-ICE vehicles, the motor launches the vehicle and is the sole power at low speed (<25mph?) for as long as the battery (or software?) permits, Then the ICE takes over. Going up a hill or passing, the motor might kick-in to aid in passing, or maintaining speed uphill.

As I say, a very base understanding.

There are different configurations/methods to accomplish this, but the concept is the same?

And yes, I know the Volt isn't a hybrid, at least not in this context.


Also, hybrids are no longer exempt from CA HOV restrictions. To get decals, a hybrid now has to be of the plug-in variety. And yes, I know that all-electrice vehicles qualify for a decal, and that electric motorcycles are already exempted.)

So why does the plugin hybrid get dispensation? Plugin model years as far back as 2011 qualify for a 2020 decal, where a 2020 and older non-plugin hybrid does not.

Probably because plug-ins can go a number of miles on battery alone. There are more and more models of PHEVs coming out all the time.

For our Prius V at least, the ICE will start up whenever the engine is cold to comply with emissions standards which is kind of dumb if you are just moving the car a short distance at low speeds.

Assuming the engine is warm, it will use only the battery up until a certain amount of power is needed to keep moving at the desired speed, and then it will switch to the ICE. This change could happen anywhere from 8 mph to 40 mph depending on the slope and how hard you are attempting to accelerate.

I would imagine the CA HOV restrictions are evolving to encourage more non-ICE type vehicles.

Motorcycles are usually allowed in HOV lanes whether they are electric or not. Toll lane regulations for motorcycles can vary by state.

...because they're motorcycles already.

All of which is funny, because ICE motorcycles actually pollute more than a modern car (per a Mythbusters episode). But I don't think they did the calculation to see if the time saved riding a motorcycle during a commute might make up for the extra pollution.

I noticed that with my Mom's Prius V when I was just backing it out of her carport to park it elsewhere. I flipped it into EV mode for the couple minutes I was in it.

I think it's due to congestion and traffic delay considerations, not strictly pollution.

I don't remember that episode, I will have to see if it's online. The vast majority of motorcycles get over 30 mpg. My 86 Civic Si used to get about 38 mpg and my 1993 motorcycle gets about 41 mpg. At least for raw carbon emissions, the car they compared to would have the same barrels of oil consumption while getting the same mileage. In many ways, motorcycle engines are 15 to 20 years behind cars in emissions and engine controls so I could see CO, HC, and particulates for the motorcycle being higher per mile if they were both made the same year.

My bike easily manages 44mpg, but it's mpp (miles per passenger) potential is much less.

Being in the HOV lane around here seldom gives me a commute speed advantage.

There's far too many violators in the HOV lane.

HOV violator issue is very easy to solve. IR camera slaved to white light camera capturing the plate. Have software count the heat blobs. Mail out $1000 ticket, problem will fix itself FAST.

So personal privacy issues as you won't even try and look at faces, just heat sources. Sure, large enough dogs will register as a human, but honestly, how many, percentage wise would do that on a daily basis?

In Seattle, the vast majority of full time lift and uber drivers have limo tint of cars like Prii and other Toyotas so no one can see they are empty in the car pool lane.

There's no reasonable expectation of privacy on a public road in CA.

I think there would be some outcry if non-violator data was saved, just as there is with the ALPRs.

Yes, thermal imaging would assuage most reasonable people. But the expense... Red light cameras, which I like, when properly set up, have all but disappeared.

For now, it's - too bad, put these on and get in the back of the car.

I don't know how all the hybrids work, but on the Prius it's not that simple. The computer manages the combination of the ICE and electric. As mikebw said, the engine always runs when it (the engine) is cold. The engine also always runs above 40MPH (technically it always rotates but doesn't always burn fuel). And generally, any decent amount of acceleration will run the ICE.
