wheel velocity
(OP)
Assume a vehicle with four independently driven in-wheel motors on slope.
How can I calculate each wheel velocity? By knowing, the vehicle velocity, slope angle and each wheel torque.
thanks,

RE: wheel velocity
There is a slippage for each wheel on the slope.
(Wheel Traction force – wheel resistance force – wheel mass * g* sine (slope angle))/ Wheel mass= wheel acceleration
So I can find wheel velocity by integration of acceleration.
Is there more to consider?

RE: wheel velocity
I am wondering , why sensors have a difficulty to measure linear velocity online?
traction force is the result of motor torque.
if you think the question is too easy and don't want to answer it, plz dont write spam.

Really?
I get infinity for the speed of the slippig wheels and you can't get vehicle speed from slipping wheel speed.
This sounds like a ridiculous homework problem. Ask your professor what he thinks the answer should be.

How do you know you don't have the right number? What have you tried? What resources have you used to arrive at your answer?
When I check calculations, I frequently ask for the source of any equations used -- so that I can verify that they're being used correctly. I'd have a hard time with "someone on this free internet site told me that this was the way to calculate wheel velocity." (I'd also question anyone using wikipedia as their source, even if it was correct ...)
