Calculating Wheel Torque for Vehicle Dynamometer Design

I am trying to come up with a formula to use with my labview program that will calculate wheel torque required to move a vehicle with some given variables. I have vehicle speed, vehicle weight, % grade or angle, tire diameter. I am trying to create a dynamometer that can determine proper motor selection based off these vehicle characterics. So if i put in a certain grade and speed, the motor will either accelerate through it or it will start back driving based off what torque my dynamometer is holding back the motor.

Thanks for any help!

- Thanks for the website, but I am not trying to create that type of dyno. I am running 2(100HP) electric motors into my differential. I am trying to replicate road conditions to spec. out a motor. The Varaiable Frequency Drives for the Motors can regulate speed or torque. I am trying to regulate torque based off road conditions. So by having the mass of the vehicle, tire coef. of friction, wheel rad, and % grad I am trying to come up with a formula that takes those varialbes and turnes it into a force that fights my motor as i am throttling up and down.
