Yes, I wish they would use them to build so EVs soon.
Do the auto majors have cross-patent agreements ? Players in many major industries do - so that they don't spend time fighting each other in courts. That also keeps new comers from ever competing effectively.LTLFTcomposite wrote:And perhaps a bunch of patents?EVDRIVER wrote:I would venture that Toyota has more expertise here, in many areas.
The Prius does not have a CVT in any conventional sense of the term. It has a patent on the planetary gear system used in the transaxle (though not w/o dispute).LEAFer wrote:And Toyota has licensed Nissan's CVT (not sure if the Prius uses that one).
It has a 80 kW motor that gives a VERY powerful acceleration. The regeneration I only very little when you take the foot of the accelerator and it goes to maximum when you apply the brake.

Much as I respect you and your opinions Daniel, I have to disagree. I LIKE the 'dead band' glide in the Prius, I just wish it was easier to find and hold. I use it all the time as I'm sure many other Prius owners do as well. If someone ahead starts to slow, I don't want to have to take my foot off the accelerator and move it to the brake for light 'slow down'. When traffic allows me to leave reasonable gaps, I don't touch the brake pedal until I need to physically stop the car at a light or stop sign. So I *want* a '3 position' accelerator pedaldaniel wrote: The only thing the Prius does wrong is putting a small amount of regen on the accelerator pedal to mimick an automatic. This results in making it very difficult to coast when you want to, since you have to find exactly the right pedal position. Separating the functions means you can go faster when you want to, go slower when you want to, and coast when you want to. With hard braking (regen) on the accelerator pedal, coasting is very difficult.
Not necessarily. Using NO energy means you aren't losing kinetic energy that you have paid for. Using 'minus' regen means losses going into and out of the battery. The best possible is maintaining speed or slowing very gradually due to rolling resistance AND using NO energy. 'Glide' a quarter mile to the red light rather than using fuel to travel 1/8th mile then regen to slow the next 1/8th. You will never recover as much energy regening the last half as you used to travel the first half (presumig no significant downhill slope of course).planet4ever wrote:Using minus energy is a lot better than no energy.
