its a concept yangwang U8 ，display the system used in U8 now
I never thought we’d see a Voronoi car, but here we are
I’ve been riding electric skateboards for almost a decade, no mechanical brakes, only regen
Did it go wrong a few times? Yep, not a good moment
It works really well, but even with all this riding time under my belt I don’t trust it in situations it’s failure would end really bad, for example, in a steep downhill, I will go slow so I can have time to jump off if needed
I know the system on them isn’t even close to automotive grade
It’s a different system. The engines here can output more than 250 hp to each wheel, and it goes reverse if necessary. And each wheel is individually controlled by the computer.
I remember something from the early Roadster development days where they were able to lock up the tires on dry pavement just with strong enough regen.
The point is that it’s easy enough to stop the tire from spinning, but traction control (and quality of tires) is what matters the most in stopping the car.
As someone who works with state of the art industrial servo motors, there is no way in hell I would drive this on the streets. Conventional steering has a very safe failure mode. There is still a mechanical link to the driver that works without power.
Yes it will have redundancy. Likely 2 motors per side. But it’s those edge cases…
So it’s like a tank. I think the tire wear is bad on this no?
BYD is having some fun!
allowing each wheel to rotate at a different torque to control the vehicle’s trajectory.
That reminds me of how robot vacuum cleaners turns
