No - MG1 is the one driven from the sun gear. MG2 is the larger one driving the ring gear and final drive. Its RPM just depends upon road speed...
The Gen4 limit for running in EV mode is 68mph - this is about 110km/h. Beyond that speed MG1 would exceed it's 17,000 RPM limit. kevin
The value of "most" is decreasing pretty rapidly. My wife's 2009 Mazda Miata doesn't have a spare, neither did my Spark EV or my current Prius....
I don't know the specific details of the Toyota implementation but in general these systems try to predict whether the car is on a collision path...
It also depends upon the drive mode - Eco, Normal or Power modes progressively accelerate faster. kevin
Only if a the transmission changed gear due to the load. When driving the flat sections of I5 in my Mazda 3 with cruse control the engine speed...
The usual reason for not running an engine at constant speed is that it will build up a ridge of wear and deposits on the cylinder wall at the end...
It's 75 mph in Ca on highway 5 but a lot of Oregon is 55 mph. I did San Jose to Eugene recently in about 9 hours total with about 65mph average....
In front wheel drive cars (not just Prius) this is usually a symptom of wear in the constant velocity (CV) joints. They wear especially quickly...
Bob Wilson has posted a lot of good information on Priuschat from experiments he has done. You should review those: Such as: Updated MPG vs MPH...
With a conventional Otto cycle engine at the end of the power stroke when the exhaust valve opens there is still unused energy left in the...
What tires did you have on your previous Prius? I had a 50.1 mpg lifetime average on my Gen2 after 67k miles. When I renewed the tires at ~35k...
The problem I see with that is that when the PM part is not running synchronously it may not produce any torque at all - if the magnetic field is...
Although you could put an induction rotor on the same shaft as a permanent magnet rotor it would need a different stator, so it would be in...
Most permanent magnet motors for EVs get a significant amount of their torque from switched reluctance in addition to that form the permanent...
During engine warm-up it is better to leave the engine unloaded than attempt to extract power from it as a generator. To do so will result in...
One part of the regime where induction motors may give benefit is at high-speed where permanent magnet motors will require field weakening,...
These are just the nominal voltage. The actual terminal voltage on the NiMH pack varies from ~170-270v depending upon SOC and current flow. I...
The Prius and others that have seen all use resolvers - usually a planar design. kevin
You cannot easily use sensorless motors where you need to easily reverse or start from zero speed with a significant inertial load. To get any...
